Embodiment Construction

[0030] Embodiments of the present invention will be described with reference to the drawings. figure 1 It is a schematic diagram which shows the schematic structure of the drive apparatus 1 of this embodiment. The drive device 1 is a drive device (hybrid drive device) for a hybrid vehicle that uses an internal combustion engine E and / or a rotary electric machine MG as a driving force source of the vehicle. This drive device 1 constitutes a so-called one-motor parallel type drive device for a hybrid vehicle. Next, the drive device 1 of this embodiment will be described in detail.

[0031] 1. The overall structure of the drive device

[0032] First, the overall configuration of the drive device 1 of the present embodiment will be described. like figure 1 As shown, the driving device 1 has an input shaft I drivingly connected to an internal combustion engine E as a first driving force source of the vehicle, an output shaft O drivingly connected to wheels W, and a rotary ele...

Abstract

To realize a vehicle driving apparatus with which an engagement device can be set in a partial engagement state easily and a responsiveness of the engagement device can be maintained at a favorable level, a vehicle driving apparatus in which a rotating electrical machine MG and an engagement device C1 are disposed on a power transmission path linking an input member I drive - coupled to an internal combustion engine E and an output member drive - coupled to a vehicle wheel is provided. The engagement device C1 includes an engagement input side member 31 coupled to the input member, an engagement output side member 32 that forms a pair with the engagement input side member 31 and is coupled to the rotating electrical machine MG5 a friction member 33 disposed between the engagement input side member 31 and the engagement output side member 32, and a pressing member 34 for pressing the friction member 33 in a pressing direction A2. A working oil pressure chamber H1 is formed between the engagement output side member 32 and the pressing member 34, and a biasing spring 35 for biasing the pressing member 34 in the pressing direction A2 when no working oil pressure is supplied to the working oil pressure chamber H1 is disposed on the exterior of the working oil pressure chamber H1.

Description

technical field [0001] The present invention relates to a vehicle drive device having a rotating electric machine and an engagement device on a power transmission path connecting an input member drivingly connected to an internal combustion engine and an output member drivingly connected to wheels. Background technique [0002] Such a vehicle drive device is known, for example, as described in Patent Document 1 below. As in this patent document 1 figure 2 as well as image 3 etc., in this vehicle drive device, between the engagement output side member (first member M11 ) and the pressing member (piston P) included in the engagement device (the first clutch CL1 in Patent Document 1; the same applies below) A working oil pressure chamber (the first hydraulic pressure chamber r1) to which the hydraulic pressure for the operation of the pressing member is supplied is formed between them. An urging spring (coil spring SPRING) that energizes the side of a friction plate F1) is ...
