Patent Images
1. A device for a level adjustment of a motor vehicle comprising:
- a damping device having a piston-cylinder unit and a screw drive that includes a spindle and a nut that is mounted on the spindle via rolling elements, to which a disc that is carrying a spring of the damping device is coupled, wherein the nut can be moved axially along the spindle, wherein an adapter sleeve axially supports the spindle and is provided with a flange that is directed radially inwards and which is axially supported on a cylinder of the piston-cylinder unit via the flange, wherein the adapter sleeve and the cylinder that is mounted on a wheel-carrier side are secured to one another so that the adapter sleeve and the cylinder cannot rotate, and wherein the adapter sleeve is decoupled in relation to the cylinder via at least one elastic element.
