Abstract

Provided is the structure of a vehicle drive device provided with a fluid transmission device, an electric motor and a transmission, said vehicle drive device being capable of improving the cooling performance of the electric motor. Even in a configuration in which an engine (12) and a first electric motor (MG1) are linked to a pump impeller (16p) of a torque converter (16), the engine (12) and the first electric motor (MG1) are positioned in a location where the torque converter (16) is sandwiched in the axial direction, thus enabling the first electric motor (MG1) to be positioned in a space (89) (inside an oil chamber) in which an automatic transmission (18) is housed. Moreover, housing the first electric motor (MG1) inside said space (89) allows the first electric motor (MG1) to be cooled by oil, thus enabling the cooling performance of the first electric motor (MG1) to be improved.

Description

technical field [0001] The present invention relates to a fluid transmission device comprising: an input-side rotating member for inputting power from a prime mover; an output-side rotating member for outputting power to drive wheels; an electric motor connected to the input-side rotating member; A structure of a vehicle drive device for a transmission of the above-mentioned output side rotary member. Background technique [0002] There is known a fluid transmission device having an input-side rotating member for inputting power from a prime mover and an output-side rotating member for outputting power to drive wheels, an electric motor connected to the input-side rotating member, and a fluid transmission device connected to the above-mentioned fluid transmission device. A vehicle drive device for a transmission of the above-mentioned output side rotary member. The drive device for a hybrid vehicle disclosed in Patent Document 1 is an example of this. In the drive device f...
