Air Spring Bellow for trucks

Passenger cars are equipped with air suspension only if they belong to the elite class. Trucks are widely equipped with it. It has relatively light weight and contribute to ride comfort. In addition, this system provides an ability to adjust the distance between the floor of the body or platform and the road surface. This greatly simplifies loading operations. As a rule, single-circuit components are installed on trucks.

Types

Various types of elements are used in the units:

• With variable effective area. It is determined by shifting the bearing flanges.
• With constant effective area. These are piston type components.

These structures may be installed on both axles. However, in trucks, rear air suspension is more common than the front one.

Malfunctions and their reasons

There are no exact replacement deadlines; replacement is carried out if pneumatic cylinders loose integrity due to abrasive wear. This happens due to constant contact of the working surface with sand or dirt. Another common failure is destruction of compressor elements after long continuous operation.

How to identify faults in the truck air suspension

A malfunction may be indicated by the corresponding indicator on the dashboard. In addition, during parking, the body is often lowered down in the area of one of the wheels. A faulty compressor may produce extraneous sounds during operation. It may also happen that it takes more time than usual to develop required pressure. The unit is not always to be replaced entirely; in some cases, only faulty components may be repaired. For this purpose, it is better to contact professionals at a service station.
