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 clutching device engageable at its planetary carrier. The planetary transmission includes an inlet ring gear that is torsionally fixed with respect to the drive shaft, and an outlet ring gear having a slightly smaller number of teeth that is disposed coaxial and adjacent to the inlet ring gear and is torsionally fixed with respect to an output shaft. The planetary transmission also has several planetary wheels engaging jointly with both ring gears, the planetary wheels connected to planetary carrier and rotating together with it.
