ABSTRACT:
A spring leg with load proportional limited damping for use on a vehicle, includes a telescoping shock absorber including a piston and cylinder and a load bearing air suspension connected to a gas pressure system and having the walls surrounding the air space thereof comprising an elastic jacket and two rigid walls fixed to the body and the axle gear of the vehicle wherein the binding units of the shock absorber are partly arranged in the air space of the air suspension. An auxiliary diaphragm has an inner rim fixed to the cylinder of the shock absorber and an outer rim fixed to one of the two rigid walls of the air suspension to define the auxiliary diaphragm as one of the bordering walls, of the air space of the air suspension. A pilot ring limits the outward movement of the cylinder of the telescopic hydraulic shock absorber from the air space of the air suspension and is fixed to the rigid wall bearing the outer rim of the auxiliary diaphragm. A bearing ring is arranged on the cylinder of the shock absorber with the piston rod of the shock absorber and is fixed to the other rigid wall of the air suspension.
