A spring arrangement for suspending a wheel suspension element relative to a vehicle body includes a spring element extending along a torsion axis and having a multiplicity of torsion portions arranged one around another in radial succession. Adjacent tors...

The actuating device has electric motor (26) for preloading a transmission gear (22) acting on a wheel guide for a torsion bar suspension (12). The electric motor is arranged at a radial distance (r) to the torsion bar. The electric motor is drifted throug...

The gearbox (6) is formed as a curved track gearbox with coupling element which engages in different curved tracks (9, 10) of two separate curved track supports (13, 14). The coupling element has an element for engaging in the curved tracks which is biased...
