Patent number: 8905881Abstract: A hybrid drive system includes an input member, a rotating electric machine, a power distributing apparatus that distributes and transmits torque transmitted to the input member to the rotating electric machine and an output member, an output gear capable of outputting torque transmitted to the output member, an output bearing that rotatably supports the output member, and a rotor bearing that rotatably supports the rotor. The entire apparatus is arranged overlapping with the output member at a position in an axial direction on a radially inner side of the output member, and a ring gear of the apparatus is integrally provided with the output member, on an inner peripheral surface of the output member. The output gear is integrally provided with the output member, on an outer peripheral surface of the output member. The output bearing and the rotor bearing are arranged overlapping at a position in the axial direction.Type: GrantFiled: February 10, 2011Date of Patent: December 9, 2014Assignees: Aisin AW Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Natsuki Sada, Tomoo Atarashi, Hirotaka Yata, Tomoaki Nishizuru, Michitaka Tsuchida
