Abstract

A first axle, such as the front axle of a motor vehicle, is directly driven by the vehicle engine or its gear shift transmission. The vehicle wheels of the rear axle can be connected automatically via two limited slip differential systems that are assigned to them and are arranged on the rear axle. The limited slip differential systems comprises a planetary transmission with a through drive ratio that deviates slightly from 1:1 and a centrifugal brake that engages at the planetary transmission with a significantly higher ratio.
