摘要： A transmission system for a vehicle that has multiple sets of driven wheels (18,24) is disclosed. The transmission system typically drives a first set (24) and a second set (18) of wheels. The transmission includes a disconnect unit (20) being operative, on application of a brake to the first set of wheels (24), to disconnect drive to the first set of wheels, while maintaining drive to the second set of wheels (18). The brake is typically a handbrake operative on the rear wheels. A disconnect unit is disclosed that can be operated by hydraulic pressure generated by manual operation of a handbrake lever, so avoiding the need to provide pump-generated hydraulic power. In a typical embodiment, the disconnect unit is disposed between a centre differential (14) and a rear differential (22). When the disconnect unit disconnects drive to the rear differential, the centre differential is preferably locked.

摘要： A transmission system for a hybrid vehicle is disclosed. The system comprises a primary input shaft (16) for receiving drive from a primary vehicle drive motor (21), such as an internal combustion engine. A secondary input shaft (42) receives drive from a secondary vehicle drive motor (34), such as an electric motor. An output shaft (14) of the system is connected to drive a final drive unit (12). A multi-speed gearbox (10) is provided to connect the primary input shaft (16) to the output shaft (14) at one of a plurality of gear ratios. There is provided input selection means (48) which, in a first configuration, connects the secondary input shaft (42) to drive the output shaft (14) and, in a second configuration, connects the secondary input shaft (42) to drive the primary input shaft (16). A clutch (21a) may be provided that can selectively connect or disconnect drive between the primary drive motor (21) and the gearbox (10).

摘要： A constant velocity (CV) joint assembly comprising a CV joint and an input member is disclosed. The CV joint that has a cage and a gear between which rotational drive can be transmitted. The input member is connected to the cage of the CV joint for transmission of rotational drive about an axis from an external component to the CV joint. The rotational drive is transmitted between the cage and the input member through interacting drive faces that are disposed in a plane that is generally parallel to the axis. The cage and the input member are retained in interconnection by fastening means that are not responsible for transmission of rotational drive between the cage and the input member. By separating the task of transmission of torque and retention of the connection between the cage and the input member, the fastening means required to perform the latter task can be comparatively light. An increase in torque capacity of the CV joint assembly does not lead to a corresponding increase in the strength requirement of such fastening means. The orientation of the drive faces ensures that there is minimal axial force between the cage and the input member.
