Pneumatic suspension for Sable: description, photo, technical characteristics

"Sable" is a fairly common car inRussia. In fact, this is the "younger brother" of GAZel. This machine is produced from the late 90's. Suspension from the "Sable" is similar to the GAZelevskaya. Front springs or screw springs can stand. But behind the Sobol there is a purely spring, dependent suspension. She acts harshly on the pits. In addition, when fully loaded, the machine sags heavily. How to solve this problem? Many people decide to install air suspension. "Sable" 4x4, the characteristics of the patency of which are comparable with a jeep, also undergoes such tuning. Well, let's look at the features of this suspension and find out how it is installed.

Characteristic

Pneumatic suspension is an alternativeClassical suspension, where the elastic elements are springs or springs. On some machines it is put at the factory. But GAZ cars are not included in this list.

Therefore, the system must be mounted non-standardly. Installed on the "Sable" air suspension (photo of it you can see in our article) allows not only to expand the technical characteristics of the minibus, but also makes it possible to adjust the amount of clearance directly on the move. Management of such a system is carried out from the cabin.

What does it give?

Why put the air suspension on the Sobol 4x4. Specifications of this car do not allow to take on board more than 770 kilograms. If you load more than the norm, the suspension will rest against the bumpers - impacts from the pits will be transmitted directly to the frame. It is not safe. But how to increase the carrying capacity without the classic increase in the number of leaf springs? Now it can be done with the help of pneumatic cylinders.

Another plus of this suspension is the softness of the stroke. With the springs it will not be possible to provide such a smooth running, as with air tanks. The machine is very "goat" on bumps, which, undoubtedly, is displayed on the comfort of control and on the condition of the transported cargo. If the Sobol travels unloaded, the cylinders can be lowered (but not below the minimum norm - we'll talk about this at the end of the article). The pendant will be soft. With classic springs, this "maneuver" will not work.

Types

There are several types of air suspension:

• Single-circuit. The cheapest and most popular type. It is installed on one axis (usually the rear). It is usually used for small-capacity trucks.
• Two-circuit. In this case, four cylinders for each wheel are mounted. This system assumes an independent adjustment of the level of clearance and stiffness of the pillows on the front and rear axles.
• Four-circuit. As in the previous case, the car is equipped with four air cushions. However, thanks to the availability of additional valves and lines, the pressure can be adjusted on each pillow individually. Usually such a system is not put on commercial vehicles. The four-circuit air suspension on "GAZelle Sable" will cost more than 80 thousand rubles. It is very expensive. However, such a system is present on many premium cars - Audi, BMW and Mercedes.

What to choose on the Sable?

Which air suspension on the GAZ Sable is betterto put? The owners' comments say that the most optimal option is the installation of a single-circuit system. The cost of a set of such air suspension on the "Sable" is 15 thousand rubles. If the minibus and the front are spring, they can be supplemented with air tanks, too. In this case, the front air suspension "Sable" will have to pay 10 thousand rubles. This will be a two-circuit system.

What is noteworthy, the bundling of these products is the same. It differs only in the number of brackets and pneumatic elements. In addition to them, the kit includes:

• Compressor.
• Receiver (average capacity - about five liters).
• Fittings, futorki.
• Airways. Usually the diameter of such tubes is 6 millimeters.
• Protective corrugated hose.
• Swap nipple.
• Solenoid valves.
• Control unit (can be completed with an arrow gauge).
• Tie-down elements.
• Hardware (bolts, nuts, washers).

Specifications

Let's look at the technical characteristics of air springs that are installed on the Sable:

• The composition of the elastic elements is a rubber compound with a nylon cord. The latter is covered in three layers. The pillow itself is a triple bellows.
• The diameter of the cylinder is from 12 to 13.5 centimeters depending on the pressure.
• The minimum height under load is 9.5 centimeters.
• The maximum height is 24.5 centimeters.
• Working pressure is from two to eight atmospheres.
• The maximum pressure to failure is 25 atmospheres.
• Holes for fastenings - a stud (three pieces) and a fitting.
• The lifting force of one pneumatic element is more than 850 kilograms.

Thus, the total carrying capacity"Sable" easily increases twice. But it is worth remembering that the load will be removed only from the suspension elements. The bridge, engine and box will suffer heavy wear. Therefore, do not zealous with overloads.

Pneumosuspension, on the "Sable" installed,has the following size: 140/3. The minimum working pressure is 0.5 bar. This is an obligatory condition, without which the long working capacity of the pillow can not be guaranteed. Otherwise, when you hit the unevenness, the material of the pneumatic element will be damaged. The operating temperature ranges from minus 30 to plus 45 degrees Celsius. In such conditions, reliable and high-quality work of elastic elements is guaranteed. But there are some rules that should be followed when operating. We'll look at them at the end of the article, but for now, let's talk about how to install the air suspension on the Sable.

Installation technology

The air spring is assembled on a specialsite. It consists of several metal plates tightly fixed to each other at different angles. Triple bellows is installed in the space between the rear axle (the so-called stocking) and the frame. The structure is as follows:

To fasten pillows to the pads are usedbolted connections. In the upper part the platform is connected to the frame. Next to each pillow connect the air hoses. They are carried towards the compressor, fixing to the frame on the screeds. It is desirable to install the compressor in the cabin. How to conduct hoses in the cabin? You do not need to drill holes for this. Technological cutouts are already provided in Sobol. Laying elements in the salon is as in the photo below: Here are the nipples. From them we connect to the compressor itself. It is desirable that the latter be equipped with a receiver. This will allow you to quickly pump air into the cushions without engaging the electric motor. Solenoid valves are installed next to the receiver. They will let the air into one or two pillows at once. The compressor and valves are powered by 12 V. It is advisable to use an additional fuse in the circuit. This will eliminate the failure of the compressor in the case of increased voltage.

What's next?

The final stage is the installation of the control unit. It can be installed on the front panel or under the seat. It is desirable that he was in a prominent place. You can use a process plug for this, which is on the center console.

Rules of operation

To air suspension on the "Sable" served ascan be longer, you need to adhere to some rules of operation. So, the manufacturer does not recommend using the system when the pressure of the cushions is below 0.5 atmosphere. Do not exceed the maximum allowable rate. Ideally, the cushion should be used at pressures from one to eight atmospheres.

Every six months, check the system forleakage. Diagnosis of the pillows is similar to checking the old tire chambers. You need to squirt the soap solution on the surface and monitor the presence of bubbles. If the pillows "poison", it can adversely affect the resource of the compressor. He will be constantly in work.

In winter, treat the cushions with silicone. As the temperature decreases, the rubber material becomes harder. Even in the absence of dirt (the presence of which on the balloon is undesirable), there is significant friction. To eliminate stress, once a month use silicone in the form of an aerosol. This will significantly extend the life of the cushions and provide elasticity to the rubber casing.

These were the basic rules for the operation of air springs. By sticking to them, you will ensure the long and reliable operation of the entire pneumatic system.

Conclusion

So, we found out what the air suspension is, how it is installed on the car "GAZ Sable" and what types it is. This is a very useful kind of tuning.
