The shock absorber module includes the elastic pneumatic element assembly, the upper support and the shock absorber assembly. The shock absorber and elastic pneumatic element are subject to service only as single units.
Shock absorber
The shock absorber assembly has a two-tube design, in which the usual spring is replaced by an elastic pneumatic element. The lower end of the shock absorber has a bushing that is attached to the lower control arm with a bolt and nut.
The damping capacity of the shock absorber is determined by limiting the flow of the working fluid through the internal channels of the shock absorber. The movement of the rod along the axis of the shock absorber is limited by the flow of fluid through the channels. This ensures the damping of vibrations that occur when the car is moving on an uneven road. At the point where the shock absorber rod exits the shock absorber body, a seal is installed that does not allow the fluid to leak out of the shock absorber and prevents dirt and moisture from penetrating into the shock absorber. In addition, this seal contains a rod cleaner.
Pneumatic elastic element
The pneumatic elastic element includes an aluminum cylinder, an upper support, an auxiliary device of the elastic element, an air cylinder and an internal support sleeve.
The air spring is made of a flexible rubber material that folds and unfolds to provide vertical movement of the pneumatic spring piston as the vehicle height changes. The air spring is secured to the cylinder and support sleeve by compression rings to ensure a tight seal. The support sleeve contains a seal housing containing two O-rings that seal the support sleeve and two O-rings that seal the shock absorber housing. The upper portion of the air spring is secured to the upper support mounted on the chassis frame by three integral studs and self-locking nuts.
The auxiliary device of the elastic element is installed on the shock absorber rod. It prevents contact of the upper support with the upper part of the shock absorber when the suspension is fully compressed, and also helps to adjust the suspension. The lower part of the elastic pneumatic element is installed above the shock absorber housing and is seated on the machined surface of the shock absorber housing. The air cylinder is rigidly attached to the seating surface with a fixing pin. The shock absorber rod passes through the central hole of the upper support. The outer end of the rod has a thread. A self-locking nut serves to attach the pneumatic elastic element to the shock absorber rod.
The upper support is an integral part of the pneumatic elastic element and is equipped with a bushing and an elastic washer. A buffer washer is installed between the upper support plate and the shock absorber rod. The upper support is secured to the shock absorber rod with a self-locking nut. The upper support is attached to the body on the chassis with 3 built-in studs and self-locking nuts. The upper plate also has a 6 mm Voss-type nipple for connecting the air line.
A cover can be installed by the dealer upon request. The cover has the same design as the cover installed on the rear air shock absorber module. It can be installed if dirt and debris get between the air spring and the cylinder under certain road conditions.
