Abstract: A wheel slip control system for motor vehicles is provided wherein when a given driven vehicle wheel spins this vehicle wheel is braked, and wherein when both driven wheels spin, the engine power is reduced. A spinning of the driving wheels is obtained by means of rotational speed sensors and a signal is fed to an electronic control unit. When a slip signal is present as a result of the exceeding of a differential speed threshold value between the driven and the non-driven vehicle axle, the engine power is controlled downward by the electronic control unit during the duration of the spin signal by means of a control element. When the slip signal drops, the engine power is again controlled upward to the desired gas pedal value set by the driver.

Abstract: A cover sleeve for the protective covering of a clearance for the passage of a steering column of a motor vehicle through a dashboard is disclosed. To accommodate adjustment of the steering column as to its inclination and length, the cover sleeve is fastened by one end to the dashboard and by the other end to a steering column casing. The cover sleeve is braced between its fastening ends by a displaceable frame which is mounted on the casing and is acted upon in its direction of displacement by a resilient tensioning element.
