Abstract

The invention relates to a device for adjusting the height of a vehicle body, having two components, which can be moved longitudinally relative to each other, and a movement thread, which is arranged between these components. The movement thread includes a partial thread which is designed as a spindle paired with a first component and a partial thread which is designed as a spindle nut paired with the other component. The partial threads are designed to be axially movable relative to each other by a rotational drive. The device also includes a locking device which bridges the movement thread in at least three longitudinal positions and which comprises an axially fixed locking ring that is arranged on the spindle in a rotatable manner and has locking cams distributed over the circumference and a shifting gate that is rigidly connected to the spindle nut in an axial manner, receives the locking cams, and includes locking stops, which are arranged at end positions of the at least three longitudinal positions and are distributed over the circumference, and switching ramps, which lie axially opposite the locking stops, are provided with slopes that decrease in the circumferential direct…
