Abstract
The invention relates to a device for the prevention of slippage on one side of a wheel on a motor vehicle driving axle with differential gearing. The device contains a sensor unit for detection of the slippage of a driving wheel and an electronic processing and control unit installed downstream. By means of an actuating element, braking or locking of a rotating part of the drive system can be effected, the actuating element being capable of being triggered by means of an electric control line. There is provided in this control line a mechanically actuatable switch that can be actuated as a function of the engine transmission position and that is deactivated when higher drive speed ranges are engaged. As a result, the device for prevention of slippage on one side, especially brake application on one side, can be activated by the safety switch as a starting assistance in performing a cross-lock function only at low speeds, preferably in first gear or first transmission speed range. Consequently, malfunctions in the electronic circuit at higher speeds in particular cannot result in hazardous and uncontrollable driving conditions.
