Abstract
In order to be able to use a four-wheel drive of a motor vehicle for different vehicle types without significant changes, it is combined into a compact drive unit. For that purpose, a four-wheel-locking mechanism and a free-wheel device with by-pass clutch are arranged adjacent one another and coaxially to one another inside of a housing surrounding the same which is adapted to be flangedly connected to an axle housing of the motor vehicle.
