The air spring of the Volkswagen Touareg is an element of the air suspension. This spare part is involved in the process of changing the position of the body relative to the road surface, which reduces the amount of vibration and rolling, as well as improves the comfort of movement.
The pneumatic cylinder performs an important function, so you should definitely familiarize yourself with its design, signs and causes of failure .
Design features of the spare part
The pneumatic cylinder is a cylindrical spare part. It is mainly made of special power rubber, which can withstand high levels of load. However, the design may also include the presence of metal and plastic components.
On one side, the air spring is connected to shock absorbers, and on the other, to special lines through a nipple.
During operation, the compressor builds up a pressure level of air springs through these lines, which causes the spare part to put more pressure on the shock absorbers. This is how you can increase the ground clearance and the position of the body relative to the road.
Why do you need an air spring
The presence of an air spring in the design of a vehicle allows you to count on the following main advantages:
- increasing the maximum possible load, which is important if the car is used for commercial purposes;
- increasing ground clearance by several centimeters;
- increasing the level of suspension resistance to punctures;
- improving maneuverability;
- improving the efficiency of damping rolling, oscillations and vibrations.
Signs and causes of failure
Despite everything advantages The air spring has a number of vulnerabilities that can lead to its failure. The main reasons for this include:
- low temperatures - rubber hardens and loses elasticity in severe frosts, this leads to accelerated wear of the spare part;
- aggressive driving - increases the level of load on the part;
- poor road surface - also increases the load;
- dirt, dust, sand - such contaminants have abrasive particles; with prolonged exposure to the surface of the spare part, they leave damage that in the future will lead to breakdown.
As for the main signs of breakdown, these include:
- a sharp decrease in ground clearance after stopping;
- increase there is no clearance between the road and the body, or it takes a very long time to increase;
- the compressor runs longer than usual;
- the suspension makes strange sounds during operation.
