Abstract

A combined spring/damper system for the support of wheel suspensions or axles on a vehicle body, with a tubular concertina which is mounted between an outer bell and a rolling piston and the meniscus of which is guided on a cylindrical inner-wall region of the outer bell and a cylindrical outer-wall region of the rolling piston. The outer bell or the rolling piston of the displacer is supported between the vehicle body and the chassis in at least one articulated support. The concertina space is filled with a fluid and communicates with a hydraulic accumulator mounted on the chassis side or on the vehicle-body side. Thus, a combined spring/damper system is provided, which includes a low-friction and virtually maintenance-free displacer.
