摘要：A motor vehicle having a front engine and all-wheel drive, wherein the wheels of the front axle are continuously driven, while the drive for the wheels of the rear axle is capable of being made either connectable or permanent via a lockable center differential or automatically by way of a viscous-coupling device arranged in the driveshaft line between the front axle and the rear axle. The coupling is arranged in such a way that the front and rear axles are coupled together essentially rigidly with regard to torque, there being provided in the train of the driveshaft line transmitting the torque between the front and rear wheels at least one free-wheeling mechanism with free-wheel lock. The free-wheeling mechanism is arranged so that-in the unlocked state-its free-wheel part coupled with the rear-axle drive is capable of overriding its free-wheel part coupled with the front axle drive, the free-wheeling mechanism being locked during drive operation and released upon actuation of the service brake.
