Abstract
A pneumatic-spring wheel-suspension leg for motor vehicles. The leg comprises a bellows () that can be rolled up over a jacket () and accommodates a pneumatics chamber (), a hydraulic dashpot inside the bellows or jacket, and a piston rod () that travels into and out of the dashpot and is attached axially and resiliently directly or indirectly at one end to the vehicle's chassis. The object is to relieve the dashpot of difficult attenuation tasks when a hard wheel suspension is necessary. The leg accordingly includes another pneumatics chamber () and the communication between the two pneumatics chambers can be partly or entirely blocked by a valve.
