Embodiment Construction

[0032] Embodiments of the vehicle drive device according to the present invention will be described with reference to the drawings. The vehicle drive device 1 according to the present embodiment is a vehicle drive device (hybrid vehicle drive device) for driving a vehicle (hybrid vehicle) including both the internal combustion engine E and the rotary electric machine MG as drive force sources for the wheels W. device). Specifically, the vehicle drive device 1 is configured as a drive device for a hybrid vehicle of a single-motor parallel system. However, in the following description, the terms related to the direction, position, etc. of each member are concepts including states having differences due to allowable manufacturing errors. In addition, the direction of each component shows the direction in the state in which they were assembled in the vehicle drive device 1. As shown in FIG.

[0033] like figure 1 As shown, the drive device 1 for a vehicle includes an input sha...

Abstract

The present invention relates to a vehicle drive device for reducing the overall size of the vehicle drive device including an inverter device and simplifying the sealing structure of an inverter housing chamber. A vehicle drive device includes a rotary electric machine (MG), a transmission (TM), a case (2), an inverter device (3), and a wiring member (40). An oil-tight space (Q) is formed by the first case part (21) and the second case part (23), and a rotating electric machine (MG) is accommodated in the oil-tight space (Q). An inverter housing chamber (P) is formed between the second case portion (23) and the cover member (51). The wiring member (40) is provided to penetrate through the second case part (23), and includes sealing members (61), (62) for sealing between the second case part (23) and the wiring member (40).

Description

technical field [0001] The present invention relates to a vehicle drive device including a rotating electrical machine and an inverter device that controls the rotating electrical machine. Background technique [0002] For example, in a hybrid vehicle, a rotating electrical machine provided in a driving device as a driving force source for wheels or a kinetic energy regeneration device generally requires an inverter device mainly composed of switching elements. Since the rotating electric machine and the inverter device are electrically connected using wiring members, they can also be arranged at different positions from each other. Considering the convenience of in-vehicle use, it is preferable to integrate them into one housing. From this point of view, Japanese Unexamined Patent Publication No. 2004-343845 (Patent Document 1) discloses an inverter device (inverter 41, 42) for controlling a rotating electric machine (generator 1, motor 2) and a storage rotating A drive de...
