ABSTRACT:
A vehicle, including a vehicle body, a chassis with wheels and tires on which the vehicle rests, a number of vehicle suspension springs and shock absorbers which are mounted between the wheels and the vehicle body and execute a change in their axial length as a function of the wheel spring travel in the form of a displacement between a piston fastened to a piston rod and a pressure tube of the shock absorber, and thereby displace a damping medium through a damping device, as well as an arrangement to fasten the piston rod and the pressure tube to the vehicle body and the wheel, characterized by the fact that the shock absorber has a damping force family of characteristics which consists of at least three individual damping force families of characteristics, the first damping force family of characteristics of which is designed so that it exerts a very low damping force, whereby this damping force family of characteristics is located in the vicinity of the normal spring deflection range of the shock absorber, and makes a transition in the decompression and compression directions respectively into damping force families of characteristics which entail a greater damping force in relation to the stroke length, compared to the first damping force family of characteristics.
