Abstract
A device () for adjusting the height of a vehicle body, including a movement thread () which is arranged between vehicle body and a wheel carrier and shifts two components () which are displaceable in relation to each other between an upper and a lower adjustment position, wherein the movement thread () is provided with two threaded parts which are rotatable relative to each other, are formed from a spindle () and a spindle nut () and are in operative engagement with each other. The one threaded part is accommodated on one component in a manner fixed axially and rotationally driven by a rotary drive (), and the other threaded part is accommodated on the other component non-rotatably and in an axially displaceable manner. In order to protect the movement thread (), in particular the operative engagement, against high mechanical loads, a switchable locking device () spanning the operative engagement of the threaded parts (A, B) of the movement thread () is provided.
