An axle drive block for a motor vehicle, comprising a first and a second differential in a driven housing. Both of the differentials are coaxially aligned planetary spur gears, the sun wheels of which are drivably connected to the semiaxes of the first driven axle. The planet wheels of both differentials mesh the joint ring gear of the sun wheels. In order to lock the interaxle differential, the housing is provided with a first striking surface interacting with a second striking surface which is pressed thereto by ball ramps.

Axle drive block with a differential lock

An all-wheel drive with hybrid drive has an internal combustion engine (), a first drive train () for a first driven axle (), a second drive train () for a second driven axle (), an electric machine () in the second drive train (), and a first clutch () upstream of the electric machine () and a second clutch () downstream of the electric machine (). In order to improve all the electrical functions and to provide an all-wheel drive which meets all requirements, the electric machine () is composed of a stator () and of a rotor () which is connected to a first element () of a three-element planetary gear mechanism (), whose second element () is connected to the first clutch () and whose third element () is connected to the second clutch ().
