A vehicle driving apparatus can handle a variety of car ranks and ensures reliability of a vehicle motor. The apparatus includes an axle housing, to which a differential-side housing of a driving unit housing is linked and integrally accommodating drive shafts of driving wheels. A first support allows elastically linking a first rotary support shaft linked to a vehicle body of the vehicle to the axle housing and the axle housing to swing around the first rotary support shaft as the center of rotation so that the axle housing is supported by the vehicle body. A second support allows a second rotary support shaft linked to the vehicle body to be elastically linked to a motor-side housing of the driving unit housing and the motor-side housing to swing around the second rotary support shaft as the center of rotation so that the motor-side housing is supported by the vehicle body.

A differential assembly includes a side gear configured to receive torque and a wedge clutch. The wedge clutch includes a hub configured to connect with a shaft and a wedge element radially disposed between the hub and the side gear. The wedge element has an inner surface seated on the hub and an outer surface engageable with the side gear. The wedge element is radially expandable and has a rested state in which the side gear and the hub are rotatable relative to each other and an expanded state in which the side gear and hub are rotationally locked to each other.

An electric drive assembly for driving a motor vehicle, comprising a housing, an electric machine with a motor shaft designed as a hollow shaft which is rotatably drivable about an axis of rotation; a planetary gearing; a differential unit with a differential, a disc clutch for adjusting a locking effect of the differential and a controllable ball ramp mechanism for actuating the disc clutch, wherein a side gear of the differential has an inner spline for inserting a shaft and a disc carrier portion which at least partially have an axial overlap; wherein the disc clutch is arranged inside and the ball ramp mechanism is arranged outside the differential carrier.
