  • Patent number: 11904696
    Abstract: Power is transmitted between the input shaft and the rotor shaft by the sun gear and the gear meshing. This eliminates the need for bearings to receive radial loads. Further, a thrust bearing disposed between the one axial end surface of the sun gear and the input shaft, and a second ball bearing abutting the other axial end surface of the sun gear are provided. This eliminates the need for a bearing for receiving a thrust load of the sun gear. A terminal block is arranged in a space opposite to the planetary gear device with respect to the electric motor caused by the reduction of the bearing. Therefore, it is possible to dispose the terminal block while suppressing or avoiding the increase in the size of the vehicle drive device.
