Abstract
A rear wheel steering is operated by a mechanical gear, which is connected on an input side to a front wheel steering. The gear has a controllable transmission ratio, a control element controlling the transmission being adjusted against spring force by a self locking free positioning motor. In the event of failure of a control unit operating the positioning motor as a function of the travelling speed, a maximum transmission ratio for deflection in the same direction of the front wheels and rear wheels is set by spring force.
