Abstract
A differential (2) for a vehicle is proposed for the apportionment of a drive torque conducted via a drive shaft on a crown gear (7). The drive torque is engendered by a motor (1) onto two output shafts (3, 4) and differential is to serve for the compensation of a difference in speed of rotation between the two output shafts (3, 4). The crown gear (7) is located in an area between the motor (1) and a drive wheel (6) of a vehicle (29) while a semi-independent suspension assembly (10) is to be found between the output shafts (3, 4) in the area between the motor (1) and the other drive wheel (5) of the vehicle, whereby the crown gear (7) and the semi-independent suspension assembly (10) are bound together via a shaft (8).

A differential (2) for a vehicle for the apportionment of a drive torque of a drive motor (1) between a first output shaft (4) supporting a first driven wheel (6) and a second output shaft (3) supporting a second driven wheel (5), the differential (2) comprising:
- a crown gear receiving a drive torque via a drive shaft connected to the drive motor (1) and the crown gear (7) is positioned on a first side of the drive motor between the drive motor (1) and the first driven wheel (6);
- a front shaft coupling assembly (10) is spaced from the crown gear (7) and positioned on a second opposite side of the drive motor (1) between the drive motor (1) and the second driven wheel (5) for compensation of rotational speed differences between the first and second output shafts (3, 4);
- and
- wherein the crown gear (7) is non-rotatably supported on a torque shaft (8) extending from the first side of the drive motor (1) transverse to the drive motor (1) to the second side of the drive motor (1) to connect with the front shaft coupling assembly (10).
A vehicle drive train having a prime mover, the drive train comprising:
- a front differential (2) for apportioning a drive torque from the prime mover (1) between a first half-shaft (4) and a second half-shaft of a vehicle drive train, the front differential (2) comprising;
- a crown gear positioned on a first side of the prime mover for receiving a drive torque;
- a front shaft coupling assembly (10) is positioned on an opposite second side of the prime mover from the first side for compensation of rotational speed differences between the first and second half-shafts (3, 4);
- and
- a torque shaft (8) supporting the crown gear on the first side of the motor extends from the first side of the prime mover (1) transverse to the prime mover (1) to the second side of the prime mover (1) to connect with the front shaft coupling assembly (10).
