Embodiment Construction

[0029] figure 1 It is a top view of the vehicle drive train assembly. figure 1 A power unit (engine) 10 connected to a manual transmission 11 is shown. The transmission 11 includes a transmission housing 7 which may include a differential housing 12 and a gear housing 13 which may be bolted together. The transmission 11 is connected to a differential 3 ( figure 2 shown). The differential 3 is connected to a power transmission unit 8 . The transmission 3 and the power transmission unit 8 will be described in more detail below.

[0030] The power transmission unit 8 is connected to the drive rod 14 through a universal joint. The drive rods 14 may include a front drive rod 14a, a central traction shaft 14b and a rear drive rod 14c. The drive rod 14 may also include one or more support bearings 15 . Said drive rod 14 is connected to a coupling 16 at the rear axle. Specifically, in the illustrated embodiment, coupling 16 is a smart lockable multi-plate clutch coupling. Su...

Abstract

A vehicle drive train comprising a transmission (11) having a differential (3) mounted in a transmission case (7). The differential has a differential carrier (3a) and a power transfer ring gear (2), where the power transfer ring gear is mounted on, or integrally formed with, the differential carrier. The drive train further comprises a power transfer unit or PTU (8) having a pinion gear (4) which is rotatably mounted in the transmission case and meshes directly with the power transfer ring gear. The differential carrier may further comprise of a helical differential ring gear (1) mounted to, or integral with, the power transfer ring gear. The power transfer ring gear may be a bevel or hypoid ring gear and the differential may be the front differential of a commercial motor vehicle. The drive train can provide a compact assembly which minimises the space occupied by existing components.

Description

technical field [0001] The present invention relates to a power transfer unit for a motor vehicle drive train and in particular, but not exclusively, to a compact arrangement of a drive train and power transfer unit including a differential carrier and a power transfer ring gear. Background technique [0002] Motor vehicles are usually set up with two-wheel drive or all-wheel drive (usually four-wheel drive). In a two-wheel-drive configuration, drive is transmitted either through the front axle and the two front wheels or through the rear axle and the two rear wheels. In some cases, a motor vehicle may include an optional four-wheel drive assembly, where the vehicle includes a permanent two-wheel drive arrangement connected to one of the axles, and optionally, the wheels that may connect drive power to the other axle. [0003] As modern motor vehicles must support more technology and associated equipment on board, there is a need to make existing power trains more compact i...
