ABSTRACT:
In a drive-slip control system (ASR) for a motor vehicle with rear-axle drive, operating on the principle of retarding again a driven vehicle wheel having a tendency to spin by activating its wheel brake, the rear-axle differential is provided with a locking device which, as the difference in the propulsive torques which can be transmitted via the driven vehicle wheels, between the latter and the roadway increases, develops an increasing degree of locking. The locking device is constructed using multi-plate clutches, which provide a frictional, limited-slip coupling between the driving ring gears and the cage of the differential on which the differential bevel gears of the differential are also mounted. In addition, the multi-plate clutches can be applied hydraulically, controlled being exercised via a solenoid valve.
