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.

Spring-shock absorbing system with tubular rolled bellows

A combined spring-and-shock-absorber system for supporting wheel suspensions or axles on a vehicle body has a tubular roll bellows (U-bellows) arranged between a wheel-bearing or wheel-controlling connection and a connection on the vehicle body side, the bellows being arranged between an outer bell and a rolling piston, the outer bell and the rolling piston, in each case, having at least partially varying diameters over the height of the corresponding component, and having walls that contact the tubular roll bellows. Both ends of the tubular roll bellows being sealingly secured on the rolling piston at segments having different diameters, the lower mounting section having a larger diameter than the upper mounting section. For this purpose, a tubular roll bellows is used, which is configured as a differential roll bellows, whose interior is filled with a fluid and communicates with a hydraulic accumulator supported on the chassis and/or vehicle body. On the basis of the present invention, a combined spring-and-shock-absorber system is developed, which contains a friction-free displacement device in a thin construction.
