Abstract
A traction slip control device for motor vehicles is disclosed including a sensor responding to a beginning slip of the driving wheels. The sensor operates via a control circuitry, the accelerator pedal-operated throttle valve at the vehicle engine, in a manner for reduction of the engine's driving power. The accelerator pedal is overriden by means of a hydraulic control element connected in. Parallel to the accelerator pedal is a piston rod arranged in a bore within a stepped piston associated with the hydraulic control element. The piston rod is, via a ball lock, adapted to be axially coupled with the stepped piston such that the piston rod is entrained by the stepped piston and shifts the throttle valve in the direction of closure in opposition to the force acting upon the accelerator pedal.
