3.2.2 AXLE SYSTEM WITH AIR SUSPENSION

FIGURE 3.2

Air suspension

(1) rigid axle, (2) steering axle, (3) rocker arm, (4) air bellows

Axle system with air suspension consists of a front rigid axle (1) and a rear steering axle (2).

Axles shock absorbing function is performed by a cylindrical rubber bellows (4) with front

elements made of metal. The upper element is fixed to the vehicle's main frame. The lower

element is attached to the end of trailing rocker arm (3) connected with a telescopic hydraulic

shock absorber featuring suitable shock absorbing characteristics.

The system maintains the trailer on the same level thanks to the use of a levelling valve (3) -

figure (3.3). Elasticity of air bellows changes according to the trailer load. In case of trailer

load increase, air is supplied from air tank (2) to air bellows (4) that are interconnected with

pneumatic conduits. Consequently, pressure inside the air bellows increases. If the trailer

load decreases, air is released from the system in order to maintain a specified trailer height.

Pressure inside the air bellows decreases.
