Patent number: 7690455Abstract: A hybrid driving unit (7) is mounted to a vehicle by coupling a coupling section (14d) at the front end of a casing member (14) with an internal combustion engine (5) and by mounting a mounting section (14c) at the rear end of the casing member (14) to a part (4a) of a body (4). Still more, a second electric motor (23), i.e., a heavy device, is disposed in the rearmost part among a first electric motor (20), a power splitting planetary gear (21), the second electric motor (23) and a transmission disposed on an axis (13) in the casing member (14). Thereby, the vibration occurring in the casing member (14) is suppressed.Type: GrantFiled: June 30, 2004Date of Patent: April 6, 2010Assignees: Toyota Jidosha Kabushiki Kaisha, Aisin AW Co., Ltd.Inventors: Seigo Kano, Kenji Omote, Satoru Wakuta, Tomochika Inagaki, Masatoshi Adachi, Masahiro Kojima

Patent number: 7621359Abstract: An output shaft is divided into a first output shaft and a second output shaft. Torque from a motive power distributing planetary gear is transferred to the first output shaft. The first output shaft is supported on partition walls by a both-end support structure via bearings. Assist torque from a transmission is applied to the second output shaft. The second output shaft is also supported on partition walls by a both-end support structure via bearings.Type: GrantFiled: September 19, 2005Date of Patent: November 24, 2009Assignees: Aisin AW Co., Ltd, Toyota Jidosha Kabushiki KaishaInventors: Seigo Kano, Satoru Wakuta, Kazuhisa Ozaki, Toshiharu Ikeda, Atsushi Ishibashi, Masahiro Kojima, Masatoshi Adachi

Patent number: 7614466Abstract: A front end portion of an output shaft is supported by a bearing mounted to an inner peripheral surface of a partition that separates a power distributing planetary gear and a speed change unit. A rear end portion of the output shaft is supported via a bearing which is interposed along a portion of the same plane along which also lies a mounting surface of a bearing in a rear wall that supports a rear end portion of a rotor of a second motor. As a result, the output shaft is supported by a twin support structure via the bearings by the partition and the rear wall.Type: GrantFiled: October 14, 2005Date of Patent: November 10, 2009Assignees: Toyota Jidosha Kabushiki Kaisha, Aisin AW Co., LtdInventors: Seigo Kano, Satoru Wakuta, Kazuhisa Ozaki, Toshiharu Ikeda, Atsushi Ishibashi, Masahiro Kojima, Masatoshi Adachi

Patent number: 7426971Abstract: A hybrid driving unit in which a first electric motor (20), a second electric motor (23), a transmission (22) and a power splitting planetary gear (21) are disposed in order from the front side (the side of an internal combustion engine) on an axis within a casing member (14). Since the first electric motor (20) and the second electric motor (23) are disposed adjacently to each other, partial cases for storing these first and second electric motors (20) and (23) may be combined, thus facilitating the accommodation for producing the unit in series.Type: GrantFiled: June 30, 2004Date of Patent: September 23, 2008Assignees: Toyota Jidosha Kabushiki Kaisha, Aisin Aw Co., Ltd.Inventors: Seigo Kano, Kenji Omote, Satoru Wakuta, Tomochika Inagaki, Masatoshi Adachi, Masahiro Kojima

Patent number: 7393296Abstract: A hybrid driving unit (7) in which a second electric motor (23) is disposed on the side closer to the front of a vehicle (the side closer to an internal combustion engine (5)) than a first electric motor (20). A casing member (14) is formed such that an inner diameter of a part thereof, in which a stator (28) of the second electric motor (23) is fixed, is larger than that of a part in which a stator of the first electric motor (20) is fixed. This allows the second electric motor (23) to be constructed so as to have a large radial dimension and, to that extent, allows the length thereof in the longitudinal direction to be suppressed. Accordingly, this allows the length of the whole hybrid driving unit (7) to be shortened.Type: GrantFiled: June 30, 2004Date of Patent: July 1, 2008Assignees: Toyota Jidosha Kabushiki Kaisha, Aisin AW Co., Ltd.Inventors: Seigo Kano, Kenji Omote, Satoru Wakuta, Tomochika Inagaki, Masatoshi Adachi, Masahiro Kojima
