Thus, as conflicts between different parts tend to increase the complexity and thus the time necessary for assembly, and also potentially reduce the quality of the assembled vehicle, the different parts of the vehicle need to be separated during the assembly operation. keep a gap between
Avoiding collisions with other components is especially important for heavier components, such as all-wheel drive systems, because heavier components are more difficult for assemblers to guide and fit into place
Also, it would be nice for the assembler to assemble the vehicle without having to reach for parts that are hidden behind other parts, as this is time consuming and potentially dangerous for the assembler

Embodiment Construction

[0036] The invention will now be described in further detail for illustrative purposes by way of example and with reference to the accompanying drawings.

[0037] figure 1An exemplary vehicle 1 is shown in . Vehicle 1 is equipped with an all-wheel drive system 2 , an engine 3 , front wheels 4 and rear wheels 5 . The all-wheel drive system comprises a power acquisition unit 6 at its front, half shafts 7 extending to the front wheels 4 respectively, and a prop shaft 8 extending from the power acquisition unit 6 to a rear drive module 9 substantially in the longitudinal direction of the vehicle.

[0038] The drive shaft also includes a constant velocity joint 19 . The rear drive module 9 is connected to the rear wheels 5 via half shafts 10 via a torque converter and a differential (not shown), respectively.

[0039] In use, such as from figure 2 It can be seen schematically that the engine 3 generates driving force, which is transmitted to the power acquisition unit through ...

Abstract

The present invention relates to a drive system and an interconnection unit for an all wheel drive vehicle (1), said drive system comprising a power take-off unit, a propshaft (8) and a rear drive module (9), said power take-off unit (6) being adapted to be attached to a vehicle's powertrain, and said propshaft (8) being adapted to transmit drive to the rear drive module (9), wherein the propshaft (8) and the power take-off unit (6) are connected by a joint for transmitting drive force from the power take-off unit (6) to the propshaft, wherein said joint between said power take-off unit (6) and said propshaft (8) comprises a female-male engagement, wherein the female (12) and male (11) engagement portions are non-rotatable in relation to each other when said joint is engaged.

Description

technical field [0001] The present invention relates to a drive system for an all-wheel drive vehicle, the drive system includes a power take-off unit, a propshaft and a rear drive module, the power take-off system is adapted to be installed on the power train of the vehicle, And the propeller shaft is adapted to transmit drive to the rear drive module, wherein the propeller shaft and the PTO module are connected by a joint for transmitting drive force from the PTO module to the propeller shaft. Background technique [0002] A vehicle's all-wheel drive (AWD) system typically includes a power take-off unit, propshaft and rear drive module. The power take-off system is mounted to the powertrain, ie, the engine and transmission, and transmits driving force from the powertrain to the rear wheels. As mentioned above, the driving force is transmitted from the engine to the power acquisition unit and further to the propshaft and the rear drive module which distributes the driving ...
