Abstract
A drive system for motor vehicles having a motor which has an axis that is transverse to the direction of travel of the vehicle comprises either a manually operable change-speed transmission which is disposed substantially beside the motor, or an automatic change-speed transmission which is coaxial to the drive shafts of the front axle. The change-speed transmission is operatively connected to the front axle differential of the vehicle, optionally via idler gears, and is operatively connected by an angle drive to a shaft which leads to and is operatively connected to the rear axle. The front axle differential is driven in known manner by a planetary gear train which has three torque-transmitting members, one of which is restrained by a preferably controllable liquid friction coupling, one coupling half of which is held against rotation, and the front axle differential, the planetary gear train, the liquid friction coupling and the angle drive are combined in a subassembly, which in dependence on the kind of the change-speed transmission is driven by idler gears having different transmission ratios.
