Abstract: An apparatus for toe and/or camber adjustment for a running gear of a motor vehicle, having a tie rod and/or a link which can be fastened at one side to a bearing fixed with respect to the car body and at the other side by a bearing can be fastened to the wheel carrier of a wheel of the motor vehicle, wherein one bearing has an adjustment element which is in the form of an eccentric and which has an eccentric shaft, which eccentric shaft can be adjusted by an adjustment drive and is assigned safety bearings arranged on both sides of the eccentric.

Abstract: A device (1) for adjusting the height of a vehicle body, including a movement thread (4) which is arranged between vehicle body and a wheel carrier and shifts two components (2, 3) which are displaceable in relation to each other between an upper and a lower adjustment position, wherein the movement thread (4) is provided with two threaded parts which are rotatable relative to each other, are formed from a spindle (7) and a spindle nut (3) 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 (6), 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 (4), in particular the operative engagement, against high mechanical loads, a switchable locking device (18) spanning the operative engagement of the threaded parts (A, B) of the movement thread (4) is provided.
