Problems solved by technology

[0006] In the conventional power transmission device, there is a problem that the vibration input of the stator is largely applied to the joint surface of the housing housing, so the rigidity of the joint surface of the housing is reduced, resulting in deformation of the joint surface, and sealing failure is likely to occur.

Embodiment approach 1

[0017] figure 1 It is a cross-sectional view of a first rotating electrical machine and a second rotating electrical machine as a power transmission device according to Embodiment 1 of the present invention. refer to figure 1 , the power transmission device 1 has: a first rotating electrical machine 100 extending axially from a first end surface 191 to a second end surface 192; a first housing 160 for accommodating the first rotating electrical machine 100; a first fixing member 150 in a second The end surface 192 side fixes the first rotating electrical machine 100 to the first housing 160; the second rotating electrical machine 200 extends axially from the third end surface 293 to the fourth end surface 294; the second housing 260 accommodates the second rotating electrical machine 200 and the second fixing member 250, which fixes the second rotating electrical machine 200 to the second casing 260 on the fourth end surface 294 side, and the first joint surface 169 on the fi...

Embodiment approach 2

[0027] figure 2 It is a cross-sectional view of a first rotating electrical machine and a second rotating electrical machine as a power transmission device according to Embodiment 2 of the present invention. refer to figure 2 , The power transmission device 1 according to the second embodiment of the present invention is different from the power transmission device according to the first embodiment in that a power distribution mechanism 300 is provided between the first rotating shaft 110 and the second rotating shaft 210 . The power distribution mechanism 300 is constituted by, for example, a planetary gear device. The power split mechanism 300 is used to divide the power from the engine into the power for driving and the power for power generation by the generator. That is, either one of the first rotating shaft 110 and the second rotating shaft 210 is connected to the engine. Noise and vibration are generated when the power distribution mechanism 300 constituted by the...

Abstract

Provided is a power dividing device capable of preventing the deformation of the mating face of a housing. A power transmission device (1) is used as a transmission for a hybrid vehicle embedding two rotating electric machines including a first rotating electric machine (100) and a second rotating electric machine (200). The first rotating electric machine (100) and the second rotating electric machine (200) both working as a motor and a generator are housed in independent first housing (160) and second housing (260) and are coupled to each other, constituting a transmission for a hybrid vehicle. A first stator (130) and a second stator (230) are fastened and fixed to the first housing (160) and the second housing (260) on the side opposite to a first mating face (169) and a second mating face (269).

Description

technical field [0001] The present invention relates to a power transmission device, more specifically, to a power transmission device provided with two rotating electric machines. Background technique [0002] Conventionally, power transmission devices are disclosed in, for example, JP-A-2009-149114 (Patent Document 1) and JP-A-2008-265517 (Patent Document 2). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2009-149114 [0004] Patent Document 2: Japanese Patent Laid-Open No. 2008-265517 Contents of the invention [0005] Patent Document 1 discloses a power transmission device incorporating two rotating electric machines, and at least one rotating electric machine has its stator fixed to the case on the joint surface side of a housing case that accommodates the respective rotating electric machines. Patent Document 2 discloses a power transmission device in which two rotating electrical machines are housed in one housing. [0006] In the conventional power tr...
