Abstract
A device for level adjustment for a motor vehicle includes a ball screw. The screw nut of the ball screw is driven by an electric motor. The spindle of the ball screw is displaceable with respect to a housing. The ball screw is supported with respect to the housing using two axial self-aligning bearings with a common pivot point such that the housing can pivot with respect to the spindle, thereby avoiding loads on the balls of the ball screw.
Claims18
A device for level adjustment for a motor vehicle, comprising a ball screw with a threaded spindled and a spindle nut which interacts with the threaded spindle via rolling bodies and which is drivable by means of an electric motor and which is mounted by two axial self-aligning bearings with respect to a housing which is displaceable with respect to the threaded spindle.
A device for level adjustment for a motor vehicle, comprising:
- a housing;
- a threaded spindle displaceable with respect to the housing;
- and
- a spindle nut which interacts with the threaded spindle via rolling bodies, which is rotatable by means of an electric motor, and which is mounted relative to the housing by two axial self-aligning bearings, the two axial self-aligning bearings each having pivot points axially offset from the bearing in a first axial direction.
