Abstract
A device for adjusting the height of a vehicle body includes a rotationally driven axially non-displaceable threaded spindle and a threaded nut, axially displaceable along the threaded spindle. A spring plate is arranged on the threaded nut for axially supporting a spring element. The threaded spindle is drivable by an actuator which is arranged at least partially within the threaded spindle. An axially displaceable additional nut is arranged axially adjacent to the threaded nut along the threaded spindle to absorb a pulse and to introduce it into the housing via the threaded spindle.

A device for adjusting a height of a vehicle body, comprising a rotationally driven threaded spindle, a threaded nut axially displaceable along the threaded spindle, a spring plate arranged on the threaded nut for axially supporting a spring element, the threaded spindle being drivable by an actuator, the actuator being arranged at least partially within the threaded spindle, wherein an additional nut, axially displaceable along the threaded spindle, is arranged to be axially adjacent to the threaded nut to receive a pulse and to introduce the pulse into a housing via the threaded spindle.
A device for adjusting a height of a vehicle body, comprising:
- a housing;
- a threaded spindle, supported for rotation with respect to the housing;
- a first threaded nut configured to move axially along the threaded spindle in response to rotation of the spindle;
- a spring plate arranged on the first threaded nut for axially supporting a spring element;
- a second threaded nut axially spaced apart from the first threaded nut and configured to move axially along the threaded spindle in response to rotation of the spindle;
- an end-stop arranged on the second threaded nut and configured to receive a pulse and to transmit the pulse to the housing, bypassing the first threaded nut.
