Device for active suspension of a motor vehicle wheel on the body of a motor vehicle

摘要

Device for active suspension of a motor vehicle wheel on a vehicle body with a load-bearing spring (2) to an upper support point on the vehicle body (1) and a lower support point to a wheel carrier (5) is supported, as well as with a parallel to the spring (2) acting electric linear drive (6), characterized in that the upper support point (3) of the formed as a helical spring load bearing spring (2) by means of a rotary drive (7) with respect to the vehicle body (1) is adjustably supported on it, and this rotary electric drive (7) to the level control and roll angle stabilization of the vehicle body is driven, while one of the damping function of the sensing loop electric linear drive (6) in the case of higher frequency of stroke movements of the wheel carrier (5) is activated.
