ABSTRACT:
An apparatus for motor vehicles having traction control and/or anti-lock brakes. In a known apparatus, a distinction can be made between an unregulated and a regulated operating stage. In the regulated operating state, the position of a control device is determined by means of a control motor. In the unregulated operating state, a position of an operating element is transmitted to a control device with the aid of the transmission device. When the operating element is adjusted and the control device is restored by a restoring spring, however, a rotor of a control motor is adjusted along with them. This requires great actuation forces and a strong restoring spring. In this system, a third rotary element is provided. In the unregulated operating state, the third rotary element returns to a position of repose. In that case there is then no longer any operative connection between the transmission device and the control motor. The control device can thus be adjusted by the operating element with relative slight actuating forces. Nor is a relatively strong restoring spring necessary. Even if an electronic control system should fail, the control device can be adjusted without problems via the operating element. The apparatus is particularly suitable for motor vehicles having traction control and/or anti-lock brakes.
