Abstract
An all-wheel limited slip differential system in the power train of the front axle and the rear axle of a motor vehicle has an intermediate planetary transmission in the direct through drive and a braking device that is engageable at its planetary carrier. A braking member is connected with the planetary carrier and the counterbraking member interacting with it is connected with the output shaft to the rear axle in a torsionally fixed manner. In order to keep the required braking moment and the braking device small, the ratio of the gear to the braking device is significantly higher than the ratio for the direct through drive.
