Embodiment Construction

[0112] Hereinafter, a drive device for a hybrid vehicle according to an embodiment of the present invention will be described with reference to the drawings.

[0113] like figure 1 As shown, in the drive device 100 for a hybrid vehicle according to the embodiment of the present invention, the engine 4 is arranged adjacent to the drive device case 40 that accommodates the generator 20 and the motor 30 in an engine room (not shown). A power control unit 60 for controlling the generator 20 and the motor 30 is mounted on the body 40 .

[0114] like figure 2 and image 3 As shown, an input shaft 1 , an intermediate shaft 2 , and an output shaft 3 are arranged in parallel inside the drive unit housing 40 , and an inner peripheral shaft 2 a of the intermediate shaft 2 is relatively rotatably surrounded by an outer peripheral shaft 2 b. In addition, in the following description, the axial direction refers to a direction parallel to the rotation axes of the input shaft 1 , the inte...

Abstract

A power control unit (60) is mounted on a drive device case (40) in such a manner that a unit-side generator connector (61) and a unit-side motor connector (62), which are arranged on the bottom surface of the power control unit (60), are directly connected to a case-side generator connector (51) and a case-side motor connector (52), which are arranged on the drive device case (40). The drive device case (40) is affixed to a vehicle body frame (80) through a mount member (70), and the point (K2) of affixation at which the drive device case (40) and the mount member (70) are affixed is disposed in the vicinity of both the case-side generator connector (51) and the case-side motor connector (52).

Description

technical field [0001] The present invention relates to a driving device for a hybrid vehicle, and more particularly to a driving device for a hybrid vehicle including an engine, a generator, and an electric motor. Background technique [0002] Conventionally, a drive unit for a hybrid vehicle having an engine, a generator, and a motor is provided with a power control unit (PCU) as a power control device for controlling the generator and the motor. [0003] The power control unit is configured to include: an inverter for a generator connected between the battery and the generator to convert the AC voltage into a DC voltage; an inverter for the motor connected between the battery and the motor to convert the DC voltage Convert to AC voltage, or convert AC voltage to DC voltage; and control unit (ECU) to control them. [0004] In conventional drive devices for hybrid vehicles, the housing housing the generator and the motor, and the power control unit are mounted separately o...
