Patent number: 7955213Abstract: An automatic transmission in which first to third clutches which can couple an input shaft to a first element of a first multiple planetary gear set and second and fourth elements of the second multiple planetary gear set, respectively, are arranged on a front side of the first multiple planetary gear set. Thus, it is possible to prevent a situation in which disengaging of the third clutch in the first speed causes the fourth element of the first multiple planetary gear set to rotate in reverse and generate a large relative rotation with the first element.Type: GrantFiled: March 29, 2007Date of Patent: June 7, 2011Assignees: Aisin AW Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Takaaki Kato, Tsuyoshi Fukaya, Akihito Hongoya, Hiroyuki Tsukamoto, Masafumi Kinoshita, Masaru Morise

Publication number: 20090293470Abstract: In an over-loading prevention device including a hydraulic pump, a control valve, and a control lever, a discharge-quantity control unit performs constant-torque control which decreases a discharge quantity in proportion to an increase in a discharge pressure in the pump to control an input torque of the pump uniformly. An operation-state detection unit detects an actuation state of the control lever. A control unit outputs a control signal that sets the pump input torque to a minimum torque according to the constant-torque control, to the discharge-quantity control unit when the control lever is operated over a predetermined speed, and subsequently changes a level of the control signal to a maximum torque according to the constant-torque control in accordance with a predetermined control pattern to raise the pump input torque.Type: ApplicationFiled: April 27, 2007Publication date: December 3, 2009Inventors: Hiroyuki Tsukamoto, Takashi Nishi
