PCT No. PCT/EP98/05640 Sec. 371 Date May 6, 1999 Sec. 102(e) Date May 6, 1999 PCT Filed Sep. 4, 1998 PCT Pub. No. WO99/12791 PCT Pub. Date Mar. 18, 1999A steering device for a motor vehicle is proposed, with an actuating member to introduce a steering movement and with a steering linkage to transfer the steering movement to the wheels. The steering device is characterized according to the invention in that the actuating member consists of a non-rotatable "steering wheel" (1), in the rim (2) of which a band-shaped or chain-like actuating ring (3), movable relative to the rim (2), and a measured value transmitter (4) for generating an electrical or electronic position signal for the actuating ring (3) are arranged, and that the steering linkage is actuated by an adjustment drive which is controllable by an electrical or electronic regulating device as a function of the position signal. The proposed mechanical uncoupling between "steering wheel" and "steerable wheels" in combination with the electronic or electrical transmission of the specified steering values on an adjustment drive brings considerable advantages as regards the formation of the transmission ratio between the incipient steering movement and the turning angle of the steered wheels and also for the transmission of the signals between the display and actuating devices on the "steering wheel" and the bodywork.
