Patent number: 11346409Abstract: A vehicle transmission includes a shaft; speed-changing gears; switching mechanisms; and a shifting mechanism. The shifting mechanism is provided with a double-meshing preventing mechanism configured to switch between a one-way state in which the switching mechanisms are hindered from moving in a downshift direction and allowed to move in an upshift direction and a free state in which the switching mechanisms are allowed to move in both the downshift direction and the upshift direction.Type: GrantFiled: June 29, 2021Date of Patent: May 31, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomoaki Yanagida, Yukihiro Inaba, Junichi Kato, Tomoyuki Kano, Tomomitsu Terakawa

Patent number: 7900741Abstract: The other end of a hub portion is located farther from an attachment portion at a lateral portion, which is located in a lateral direction with respect to the vehicle, than at a vertical portion, which is located in a vertical direction with respect to the vehicle. The vertical portion of the hub portion has a concave end face on the side of the other end of the hub portion, which is formed to get closer to the attachment portion as the concave end face approaches a portion closest to the attachment portion substantially at the center of the hub portion in the lateral direction.Type: GrantFiled: August 21, 2008Date of Patent: March 8, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takahiro Nakazato, Tomoyuki Kano

Patent number: 7769480Abstract: In an inspection procedure of a completed product of an automatic transmission main body at a unit factory, a control system transmits a control signal to an actuator to receive characteristic data (hardware performance information) output in response to operation of the automatic transmission main body according to the control signal. The hardware performance information of the automatic transmission main body is brought into correspondence with hardware identification information, and set in a database as learning value data. The learning value data of the automatic transmission main body is transferred to a vehicle factory to be aggregated in a database management system at the vehicle factory.Type: GrantFiled: May 24, 2005Date of Patent: August 3, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tomoyuki Kano, Masato Matsubara

Patent number: 5954173Abstract: There is disclosed a drive force transmission apparatus which includes a first pressing-force generation unit for generating a pressing force in accordance with a rotational speed difference between driving and driven shafts, and a frictional clutch which is brought into an engaged state by the pressing force generated by the first pressing-force generation unit in order to transmit torque in accordance with the rotational speed difference between the driving and driven shafts. The drive force transmission apparatus further includes a second pressing-force generation unit disposed opposite to the first pressing-force generation unit with respect to the frictional clutch. When needed, the second pressing-force generation, unit is operated to bring the frictional clutch into a firmly engaged state, thereby improving the traveling performance of the vehicle under severe traveling conditions, such as an attempt to extract a wheel trapped in a gutter or the like, traveling on a rough road, traveling on sand, etc.Type: GrantFiled: July 16, 1997Date of Patent: September 21, 1999Assignees: Toyoda Koki Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Toshifumi Sakai, Kunihiko Suzuki, Naoyuki Kokubo, Masayuki Shimada, Tomohiro Maruyama, Hisashi Fukuchi, Satoshi Ashida, Hirokazu Suzuki, Tomoyuki Kano
