Abstract
An all-wheel drive for a motor vehicle has a first transmission line which starts out from a change-speed gearbox and leads to the rear axle and a second transmission line branching off from the first transmission line and leading to the front axle. The second transmission line can be connected by a permanently acting all-wheel locking system as a function of the rotational speed difference between the drive shaft and the output shaft of the all-wheel locking system. In the first transmission line, a separating coupling is inserted behind the branch-off point to the second transmission line, this separating coupling being operable as a function of parameters of the motor vehicle.
