Estimating the term…
The invention elates to an electric drive assembly for a multi-axle driven motor vehicle which comprises an internal combustion engine, a multi-step transmission with an output shaft for driving a rear axle, as well as an optionally driveable front axle. The drive assembly comprises an electric machine (6), a reduction gearing (7) drivingly connected to the electric machine (6), a driveshaft (9) drivingly connected to the reduction gearing (7) and drivingly connectable to a front propeller shaft (65) for driving the front axle, and a housing 5 in which the electric machine (6) and the reduction gearing (7) are arranged. The housing (5) comprises connecting means (16) for connecting the drive assembly (2) to the multi-step transmission. The electric drive assembly is designed such that, with the electric drive assembly mounted at the multi-step transmission (56), a rear propeller shaft (57) can be connected at least indirectly to the output shaft of the multi-step transmission for driving the rear axle. Furthermore, the invention relates to a motor vehicle with such a driveline assembly.

An electric drive assembly for a multi-axle driven motor vehicle that comprises an internal combustion engine, a multi-step transmission with an output shaft for driving a rear axle, and an optionally driveable front axle, said electric drive assembly comprising:
The electric drive assembly of claim 5, wherein an actuator is provided for actuating the coupling, which actuator is actuated one of electro-mechanically and electro-magnetically.
The electric drive assembly of claim 1, wherein the reduction gearing is a single-step cylinder gearing and comprises a reduction ratio of four to six.
The electric drive assembly of claim 1, wherein the electric machine comprises a nominal voltage of 60 Volts maximum.
The electric drive assembly of claim 1, wherein the housing comprises a torque support mechanism.
A multi-axle driven motor vehicle, having a rear axle driveable via a rear propeller shaft, a front axle driveable via a front propeller shaft, a longitudinally mounted internal combustion engine, a multi-step transmission drivingly connected to the internal combustion engine and an electric drive assembly, the electric drive assembly comprising:
The motor vehicle of claim 12, wherein the electric drive assembly comprises a through-driveshaft for transmitting torque through the housing, wherein an input part of the through-driveshaft is connected to the output shaft of the multi-step transmission and wherein an output part of the through-driveshaft is connected to the rear propeller shaft.
The motor vehicle of claim 12, wherein the front axle comprises a front-axle differential and two sideshafts arranged to drive front wheels, wherein the front axle differential distributes a torque introduced by the front propeller shaft to the two sideshafts, wherein a coupling is arranged in the power path between the driveshaft of the electric drive assembly and the two front wheels.
The motor vehicle of claim 12, wherein the electric machine is integrated into an on-board power supply of the motor vehicle.
