Abstract
A power transmitting device includes a front housing member, an inner shaft, and a main clutch that selectively permits and shuts off transmission of torque between the front housing member and the inner shaft. The power transmitting device is rotatably supported by a bearing arranged outside the front housing member. An intermediate member having a thermal expansion coefficient lower than the thermal expansion coefficient of the front housing member is arranged between the front housing member and the bearing.
Claims11
A power transmitting device comprising:
- a first rotor having a cylindrical shape;
- a second rotor having a shaft-like shape, the second rotor being provided inside the first rotor to be rotatable relative to and coaxial with the first rotor;
- a clutch mechanism that selectively permits and shuts off transmission of torque between the first rotor and the second rotor, the power transmitting device being rotatably supported by a bearing arranged outside the first rotor;
- and
- a relaxation member provided between the first rotor and the bearing, the relaxation member relaxing a stress applied to the bearing in a radially outward direction by thermal expansion of the first rotor.
