Mercedes was not the first: who and when was the first to invent gullwing doors? 

principle of operation, pros and cons, how to do it

When tuning a car, many car owners do not stop at installing alloy wheels, various body kits and adding spoilers. To add individuality to the vehicle, some car owners decide to equip the car with doors that open vertically instead of conventional doors. Such cars, whose doors open upward, always evoke admiring glances.

To install the lambo structure, it is necessary to alter the door mounting points. You can solve this problem on your own.

What types of lambo doors are there?

For the first time, the vertical principle of opening car doors was presented by Italian automakers more than half a century ago in one of the concept cars. The Lambo design was named after the Lamborghini company, whose engineers first developed a special door hinge. One part of the hinge is fixed in the corresponding part of the body with the help of fastening bolts, and the other holds the raised doors open.

Cars with doors that open upward have gained popularity among fans of “cool” tuning who want to make their car look like a sports car. Automatic Lambo doors are mounted on special hinges that secure the doors in the open state, regardless of their angular position.

Cars with doors that open upwards have gained popularity.

This design has several names - guillotine doors, scissor doors or lambo doors, and includes the following components:

Existing lambo devices are divided into the following types:

Fastening of special hinges is carried out both using electric welding and by bolting. The design of the hinges allows you to install Lambo doors on almost any car model.

Existing Lambo devices are divided into several varieties

The principle of operation of Lambo doors

Doors that open upwards function quite simply:

The secret to how a swing door works lies in the well-designed hinge design.

Pros and cons of an opening door

When planning to install Lambo doors on a VAZ 2114 or another car model, you need to familiarize yourself with the advantages and disadvantages of such doors.

Main advantages:

Along with the advantages, there are disadvantages:

It is also important to be careful when operating the swing door and open it carefully so as not to deform the hinges.

Lambo devices have many advantages

Purchased and self-made hinges

In order to tune a car, you will need to make Lambo hinges yourself or buy ready-made ones. It is advisable to first find out how much Lambo hinges cost in order to estimate the possible cost.

Making Lambo hinges for fastening doors

If you have the skills to perform plumbing work, you can try to make Lambo hinges with your own hands. To do this, you will need to find a drawing of a hinge suitable for a specific car model and purchase the necessary materials. You will need sheet metal and a gas shock absorber with the required rod length and load capacity.

How to make car doors open upwards - do-it-yourself installation

It is important to understand in detail how to make a Lambo door so that the hinge mechanism works smoothly and the doors fit snugly into the opening.

In order to install Lambo doors with your own hands, you will need to perform the following work:

You can install Lambo doors yourself

Let us dwell on the features of the main stages.

Drawing for universal Lambo hinges and other preparatory work

On specialized websites it is easy to find a ready-made sketch or diagram of a loop. You need to familiarize yourself with the drawing, transfer it to the metal, cut out the blank and fit it to the shape of the opening.

The material for assembling the mechanism is easy to purchase, and the tools for performing the work are always available in the arsenal of home craftsmen.

Installing and adjusting hinges on cars with doors that open upwards

Self-made or purchased hinges should be applied to the place of fixation and make sure that their size and shape match. If necessary, the mechanism should be adjusted. The loop can be secured using electric welding or ordinary bolts. It is worth giving preference to the second option, as it makes the adjustment easier.

Installation of car doors and door openers

Installing Lambo doors to a pre-attached hinge requires care. After screwing the door leaf, it is necessary to check how the hinge mechanism works, check the connection of the door to the seal and make sure that it can be opened easily. With an increased weight of the structure, additional reinforcement of the body will be required.

Types of mechanisms

The company is represented on the lifting equipment market with the following versions: T-105, F-20, T-75, L-80, T-70, S-35 and T-65. Each model is designed for a specific weight and types of facades.

Soft and easy door movement is achieved thanks to the Kinvaro F-20. And with the help of a stupor, you can set your own individual opening angle. It has a built-in special shock absorption system, thanks to which even the heaviest facades will close smoothly and silently. All this is achieved through detailed configuration settings. This model also has protection against accidental damage (to fingers), which will greatly protect its use, and its sophisticated design will fit any kitchen furniture.

Special qualities of the device:

• Easy and silent movement;
• Closing depreciation;
• Large selection of models for any weight and façade size;

• Works quietly;
• Like other models, it has great corrosion resistance;
• Many different models for any door options;
• Impact protection with built-in shock absorption.

After analyzing the information about the models of leading brands of manufacturers, you can draw the appropriate conclusions for yourself. Before buying lifting mechanisms, you need to measure everything, it is advisable to make a drawing of how your kitchen unit will be located and be sure to pay attention to the weight, size, and shape of the facades. All this will help you get the desired result and realize your design abilities.

10 cars with the most unusual doors

1. Alligator doors on the Koenigsegg CCR

2. Door-mounted seats on the Peugeot EX1 concept speedster

In 2010, for its anniversary, Peugeot showed the Peugeot EX1 concept speedster. An interesting feature of the prototype was the driver and passenger seats mounted on the doors.

3. Flip-up hood on Sterling Nova

Sterling Sports Cars, based in Pittsburgh, Pennsylvania, makes unusual kit cars. It does not have doors in the usual sense. Instead, the entire top section, along with the windshield, roof and part of the side walls, rises up, exposing the entire interior.

4. Downward sliding doors on the BMW Z1

There was a time at BMW when designers were not afraid to create. This is how the small BMW Z1 roadster appeared, whose doors were hidden in a niche under the doorway.

5. Gullwing doors on the Mercedes-Benz 300 SL

This is certainly an example of when a car became popular thanks to its unusual door mechanisms. Everyone knows this elegant supercar as Gullwing, which translates as “gull wing”. Indeed, you look at a car with open doors. Reminds me of a bird taking off, doesn’t it?

6. Microdoors on Smart Crossblade

7. “Butterfly wings” doors on McLaren P1

8. Suicide half-doors on the Mazda RX8

9. Guillotine doors on the Lamborghini Countach

10. Swan doors on the Aston Martin Rapide S

The doors of the Aston Martin Rapide S sedan are a variation of conventional doors. Only they do not open horizontally, but at a slight angle. Add to this the lack of door frames and you will understand why they were nicknamed “swan”.

Installation Features

The design of the Lambo door consists of a hinge attached to the car body and a shock absorber that ensures the door is lifted and held open. Based on this, when choosing parts, special attention should be paid to their quality and reliability.

Lambo door mounting kit

Before converting the VAZ 2109 model, the first thing you should take care of is strengthening the places under the wings where the doors will be attached. This cannot be avoided, since the initial thickness of the metal is not enough.

To install lambo doors you will need special hinges. They can be purchased at a specialized store or made independently. If you prefer to do everything yourself, then you will need powerful shock absorbers (you can borrow them from minibuses, in which they ensure the opening of the rear door). In addition to them, we need the same devices from Moskvich. They should be installed on top, and more powerful ones - on the bottom, since they will take on the main load. As a result, the doors will perform their functions properly.

During the installation process, it is necessary to ensure that in the closed position the door fits evenly against the seals, and when opening it cannot damage the trim and body.

There is one more nuance: the integrity of the car’s wings can only be ensured by cutting off a certain part of the rack, which will definitely need to be strengthened. To do this, it will be enough to weld a channel with a thickness of at least 3 mm to it.

There are several ways to fix the hinges to the body: using a bolted or welded connection. After this, they should be adjusted using movable bolts.

Using ready-made kits is much easier and more reliable, but no matter what method you choose, the result is the same - you will get an original car that stands out from the mass of stamped models of the same type.

Why do most cars' doors not open upwards?

Gullwing doors look amazing, but they have not become popular in the auto industry.

Many of us have heard more than once about “Gullwing” car doors, which are also called “Seagull Wings” or “Falcon Wings.” This name was not invented by chance. Gullwing doors do not open sideways like traditional doors, but upwards.

As a result, the car, with the doors open, looks like a bird in flight. Recently, for the first time in many years, attention to this door design has again become heightened. It all started after the premiere of the world's first electric crossover, Tesla X, which is equipped with this door system.

During the presentation of the car, the head of Tesla demonstrated the advantages of “Gullwing” doors for operating a car in an urban environment. For example, such doors are indispensable in hard-to-reach urban spaces (parking lots). With such doors it is especially convenient to place a child in a child seat without bending over.

We all know that the Mercedes company first began to use such a door design back in 1952, introducing the sports model Mercedes-Benz 300SL (W194).

Since then, many automobile companies have repeatedly produced cars that had a similar door design. But, nevertheless, such car doors have not become popular in the auto industry. Why haven’t practical, efficient and beautiful doors taken root in the real world? Let's try to answer this question.

1 Designing the perfect gullwing door is challenging

At first glance, Gullwing car doors do not present any particular design difficulties. But this is true when we are talking about ordinary doors. But when it comes to designing doors that open upward, designers and engineers face enormous challenges.

Firstly, the main feature of Gullwing doors is their heavy weight. Therefore, the door opening mechanism must be able to lift heavy doors up without any problems. Agree that lifting the door up is not the same as turning the door to the side on hinges or a hinge. Also, when designing gullwing doors, you need to take into account that the driver and passengers do not have to make much effort to open the doors upward.

Also, the complexity of the design is related to the issues of excessive load of doors on the roof. When creating the design of such doors, engineers usually face the problem of protecting the car roof from deformation. Including, as a rule, “Gullwing” doors are actually part of the roof of the car. As a result, when designing such doors, engineers must take into account the tightness of the doors, which should protect the car interior from moisture. That is why, during the debut of the Tesla Model X, Elon Musk repeatedly mentioned new door seals.

In general, of course, many of the difficulties in creating “Falcon Wings” or “Seagull Wings” doors are not insurmountable difficulties for engineers. But nowadays it’s easier to get around these difficulties by equipping cars with regular doors.

2 Doors that open upward can be annoying for drivers and passengers

Pay attention to the GIF photo. It speaks for itself. In the photo you can see how the driver of a Mercedes SLS AMG is faced with the problem of closing the door. Of course, such a problem can be solved with the help of an electric drive, as Tesla did by equipping its electric crossover with electric rear “Gullwing” doors. But when using such technology, the cost of the machine increases and the likelihood of door failure during operation increases. Still, mechanical systems are more reliable than any electronics.

Version in favor of Mercedes-Benz

These legendary W198 cars were in turn based on the MB W194 racing cars developed in 1952. They used an innovative tubular frame design with many interlocking triangular sections. The frame was extremely light (81 kg) and yet strong. The downside was that these pipes took up a lot of vertical space on the sides of the car, leaving very high sills.

In an open car like a convertible, this isn't such a big deal, but add a roof and you'll find that traditionally suspended doors (hinged at the front of the door) leave very little room for occupants to get in and out. It's simply impossible to use the car this way.

So, it is believed that the savvy engineers and designers at Mercedes decided to make the opening larger, extending it along with the door to the roof and attaching hinges at the top, creating those same “gull wings” that we all know and love.

What types of car doors are there? 5koleso.ru

An unusual door design is a great way to make any car more exclusive and attractive. Let's see what "non-standard" car doors can be

Lambo doors

Guillotine or scissor doors eventually became a hallmark of Lamborghini. However, the first guillotines appeared on the 1968 Alfa Romeo Carabo concept car. But the first production supercar with scissor doors is the Lamborghini Countach. Such doors were invented not so much for beauty, but for practical reasons: due to the poor visibility of some supercars, when driving in reverse, you often have to drive the car with the door open (with ordinary doors it is much more difficult to do this), in addition, Lambo doors do not extend beyond limits the width of the car track and is convenient when parking in a narrow place.

gull wing

Gullwing doors open upward and are hinged on the roof. The first and most famous owner of gull-wing doors is the Mercedes-Benz 300 SL. The main advantage of such doors is, again, saving parking space (for example, to fully open the side doors of the DeLorean DMC, only 27.5 cm is required). But there are other motives: in the Volvo YCC women's concept car, gull wings were necessary to easily accommodate children and shopping bags.

Butterfly wings

Butterfly wings are a hybrid of “guillotines” and gull-wing doors. They open upwards and outwards at the same time, so they provide even easier and faster exit by saving additional space. The most striking cars with butterfly doors are the McLaren F1, Alfa Romeo 33 Stradale, Enzo Ferrari supercars and the relatively affordable Toyota Sera compact.

Rear hinged doors

Rear-hinged doors (the hinge is fixed on the rear edge) are famous mainly thanks to Rolls-Royce products. They are often called suicide doors. The fact is that when the bolt is released while the car is moving, such a door can suddenly open and come off under the influence of a headwind.

Top hung doors

Top-hung doors are much less common than others. Actually, such a door is a roof with a windshield, which, as a rule, is raised and moved back to provide access to the passenger compartment and the driver. The absence of pillars provides a viewing angle of more than 180 degrees, but there are also disadvantages: in the event of a rollover, you can only get out of the car by knocking out the windshield, and in the event of rain or snow, it is impossible to get into or out of the car without getting the interior wet.

Door-seats

Doors paired with seats are a unique car door technology that has only been used on one concept so far. The Peugeot EX-1 high-speed electric car was created for the company's anniversary in 2010. Unusual doors are not the only advantage of the concept; the EX-1 set a bunch of records among cars under 1000 kg. It’s hard to imagine when something like this will appear in mass production: the door-seats, although beautiful, are terribly uncomfortable.

Types of guillotine type doors

To this day, several types of rising doors have been developed:

• Standard. Rising 90 degrees;
• VLS doors. Open upwards and not much outwards;
• Rising 130 degrees;
• Combined. They can open either upwards or in a standard way.

Features of installing Lambo doors on a VAZ

For those who are concerned about the question of how to make Lambo doors, first of all, you need to start by looking for Lambo hinges. Today, ready-made Lambo hinges for VAZ can be purchased for 10–20,000 rubles, and they are made quite professionally.

But if this price seems excessive to you, then you can make them yourself. And it will cost you no more than 5,000 rubles.

Advantages and disadvantages of scissor doors

The main advantage of such doors is their simply crazy appearance. A car with such exterior elements will always attract attention, which is what those who install them are trying to achieve.

Another important advantage is the ability to open doors in tight parking conditions. Another plus is the convenience of visibility to the rear when reversing, but today, in the age of rear-view cameras, this problem is solved in a different way.

There are also disadvantages to such doors:

1. First of all, Lambo hinges are less reliable than standard ones; due to high loads, they quickly weaken and the doors no longer hold in the open position.
2. The second disadvantage is the inability to open the door in rooms with low ceilings, for example, in garages or underground parking lots. Also, often, in case of an accident, especially with a rollover, the doors do not open at all.
3. However, the main disadvantage and obstacle to installing Lambo doors on a VAZ is their high cost.

Conclusion

Difficulty installing lambo hinges.

When installing lambo hinge kits, a number of technical issues arise that have to be resolved, and each car has its own problems, which only professionals can solve.

• Removing doors and fenders - already at this stage, some cars present surprises.
• Installation of the kit - if the kit is completely suitable, then the locations of the hinges are calculated and they are installed in their standard places. However, things don't always go so smoothly.
• If the hinges do not fit into the standard places, then the design of the kit requires modification. And refinement, in turn, requires specialists and special equipment.
• After the hinges are installed, you need to install shock absorbers. This requires calculating the correct installation location so that the load on the shock absorbers and the car body is distributed evenly.
• Some vehicles require body reinforcement.
• Finally, the wiring and fenders of the car are attached.

It's really an unusual project, isn't it? If at first glance it somewhat resembles a Lamborghini, then upon closer inspection, features of past years are visible. In fact, the car was created back in the late sixties. The Australian manufacturer designed the car for “research” purposes. Thus, I tried to study design trends.

The feature of this model was the complete absence of doors. But how can this be? Instead, the creators decided to use a special lifting mechanism that moved part of the body forward and upward. You can guess that this project was never destined to make it into the series. Only after a while, in the 2000s, the car was restored, which aroused great interest among classic car lovers at an exhibition in Melbourne.

How to make car doors open upwards

Lambo doors are a door design that opens vertically. The design received its name from a similar development on a Lamborghini car.

The mechanism of operation of the device is as follows: when opening, the car door first opens horizontally (about 30 degrees), and then the lambo hinges, due to the built-in shock absorbers, lift it to a vertical position (usually 90 degrees). The design itself, which allows you to open car doors in this way, consists of hinges and gas shock absorbers that are attached to the hinges. The shock absorber softens the operation of the mechanism, making it smooth and not requiring much effort to open the car. Its gas varieties, which are used for vertical doors, have increased wear resistance and stability even under constant and heavy loads. The installation of the device allows it to be installed at different angles.

Lambo doors on VAZ 2107

In Russia, such a service as installing lambo doors has only recently existed and is not yet very popular due to the high cost, as well as the mechanism, material or individual components. Therefore, drivers of domestic cars and some foreign cars are trying to make Lambo doors with their own hands.

The ability to find the drawings yourself simplifies the situation. Calculating how much you will need to pay for installation includes the cost of components, as well as the labor fee for the miller who will assemble the door.

Manufacturing process and features

In the process of making Lambo doors, the main nuance is the manufacture of hinges responsible for opening them. To make hinges for the Lambo door with your own hands, you will need to purchase shock absorbers from Ford Transit (those that raise the rear hatch) and luggage shock absorbers from Moskvich. Install a foreign shock absorber at the bottom of the structure, which will bear the main load. Attach the shock absorber of a domestic car on top - it will help the device stay in any position.

For ease of alignment, you will need to make marks on the door arch, as well as the door. When trying on, take into account the location of the lambo door - it will not touch the front window pillar.

Various versions of drawings for this kind of construction can be found on the Internet. The most popular drawing, which is used as a basis by many craftsmen, is a diagram with an opening angle of 30 degrees outwards and 90 degrees upwards.

The process of installing a lambo hinge
Some versions of the drawings indicate the need to screw an additional strictly vertical tube from the bottom of the structure, which provides better support.

Some blueprints suggest there is a button that will raise your car door, but it will still need to be opened manually to the side. To make it easier to open the doors, you can attach a handle to the bottom of the structure, which will allow you to close the door while sitting in the vehicle.

There are a number of other features that you need to consider when making and trying on devices:

• To avoid damaging the car fender, remove a piece of the door “goose” and cut out a part of the pillar for it. To do this, you will need a 3 mm thick stand, which is cut with a channel;
• You can also weld a reinforcement into the door to prevent damage to the mechanism and injury when opening or closing the structure;
• Car enthusiasts installing such a structure need to check the alignment of the holes and adjust the gaps. If necessary, they should be covered with a rubber or sealant seal;
• When operating in harsh climate conditions, shock absorbers may wear out ahead of schedule.

Classification

Depending on the type of installation, the following model drawings are distinguished:

The variety of mechanisms and possibilities of how many degrees the doors open has led to the existence of the following mechanisms:

Owners of domestically produced cars can install a similar mechanism. Many people are interested in how much effort it takes and how much it costs. If you have the skills of a turner-milling machine, have a friend with experience in this field, and also purchased the necessary materials yourself, then production will cost you several thousand rubles (purchased Lambo doors cost several tens of thousands, which is an exorbitant amount for a domestic car). Plus, due to the location of the hinges on domestic cars, you won't need to make a lot of adjustments to get the doors to open upwards.

Advantages and disadvantages

There is an opinion that homemade Lambos installed on the “nine” in rainy and snowy weather can cause moisture to leak into the car. These fears are not confirmed by anything: problems of this kind are excluded.

Despite this, there are still some disadvantages:

• shock absorbers involved in the door lifting process will require constant replacement. This is due to the harsh climate characteristic of Russia. And in order to carry out the replacement, you will have to disassemble the entire front part of the car, since otherwise you will not be able to get to this element;
• The installation of hinges for lambo doors is accompanied by filing the edges of the wings. This cannot be avoided, since an absolutely unacceptable situation will arise: the hinges will rest against the wings. Removing the edge, in turn, will cause deterioration in sound insulation. In addition, when driving at high speeds, the wind will blow into the cabin, and if in the summer this can be regarded as a plus, then in the winter it is unacceptable;
• the need for frequent door adjustments. It is a necessary measure, since otherwise the Lambo doors will sag, touching and knocking down the paintwork of the threshold and doorway. You should be prepared for the fact that such doors are unlikely to fit perfectly into place, as evidenced by the gaps;
• long-term addiction to opening/closing doors;
• significant material costs for tuning;
• restrictions on the height of the parking space, since the door will open upward;
• in the event of an emergency (for example, as a result of an accident, the car turned over on its roof), it may be difficult to exit the cabin.

Along with the disadvantages, there are also advantages:

• spectacular appearance that will not leave any motorist or ordinary passerby indifferent;
• ease of parking a tuned car. On the improved VAZ 2109 you can easily find a place even in cramped spaces, since there is no need to take into account the margin for opening the doors before parking;
• excellent visibility;
• the ability to convert Lambo doors into regular ones is ensured by the location of a special hinge on the Lambo (it is located in the same place as in the classic door design).

Which kit to choose for installation

For self-installation, it is better to choose one shock absorber. It is not so bulky and there will be no difficulties during installation.

Kits that include two shock absorbers have their own nuances. The whole complexity lies in the broad mechanism. Under such a kit you will have to “inflate” the wings, which requires more professional skills.

It is better to avoid expensive kits when installing them yourself.

Making lambo loops

How to make a folding mechanism yourself if you have no skills? To do this, you can make the drawing yourself. Another option that makes the work easier is to find a ready-made drawing.

They differ in connection types:

• welded - welded to the body using a welding machine;
• screwed - screwed to the car with bolts.

A 130-degree door has a different design than a 90-degree door, but can also be welded or bolted.

To make loops you will need:

• drilling machine;
• screwdrivers;
• drills of the required size;
• metal plate 0.5cm thick, thickness is key as the loop will hold a heavy
• design;
• marker for drawing a picture on the plate;
• drawing of a loop on paper.

Work order:

• apply the contours of parts to the metal, mark holes and recesses;
• drill out the spare part along the contour - taking your time with the drill to go through every centimeter;
• then drill the finished part for fastenings with bolts; how many there will be is decided by the car owner, depending on the location of the fastening;
• process the metal - clean and paint.

Purchased and self-made hinges

In addition to store-bought Lambo mechanism kits, there are homemade options.

Purchased hinges

The advantages include:

• precision manufacturing of parts;
• strong metal, designed to hold a certain weight;
• tested loops that have been certified;
• guarantee.

The disadvantages of mechanisms made using professional equipment include:

• price, store-bought ones are more expensive than home-made ones;
• small selection for the model range of cars.

Self-made guillotine loops

How to make Lambo doors yourself if you like them? Guillotine doors on cars have their advantages:

• you can make them in your garage and choose the metal and its thickness yourself;
• it is possible to actually manufacture all the mechanisms and hinges to suit the desired design of the car.

The disadvantages include:

• manufacturing inaccuracy;
• no warranty.

Most car owners who decide to do tuning install self-made parts.
