Patent number: 8808134Abstract: An automatic transmission includes an input shaft, an output member, a first planetary gear system, a second planetary gear system, a third planetary gear system, a fourth planetary gear system, and an engagement mechanism. The input shaft is configured to be rotated with power of a driving source relative to the transmission case. The output member is to output rotation of the input shaft using multiple gear-shifting. The multiple gear-shifting is provided by setting at least three of first to third clutches and first to third brakes in a connection state.Type: GrantFiled: October 26, 2011Date of Patent: August 19, 2014Assignee: Honda Motor Co., Ltd.Inventors: Noriaki Saitoh, Soichi Sugino, Toshikazu Kouno, Kohei Iizuka, Mariko Shibamura, Shoji Machida, Jorg Muller, Rico Resch, Mirko Leesch

Patent number: 7222552Abstract: A controller for a transmission capable of preventing an occurrence of a gear squeak caused by a malfunction of a synchronization mechanism. The voltage determination section 24 performs a shift operation of a transmission by determining a control input Vin to a shift motor 13 so as to match an actual position Psc of a coupling sleeve 6 grasped by an actual position grasping section 21 with a target position Psc_cmd of the coupling sleeve 6 set by a target position setting section 22.Type: GrantFiled: April 18, 2005Date of Patent: May 29, 2007Assignee: Honda Motor Co., Ltd.Inventors: Toshikazu Kouno, Eijiro Shimabukuro, Yuji Yasui, Junya Tachikawa

Patent number: 6432888Abstract: The present invention is directed to a grease for a rolling bearing containing poly-&agr;-olefin synthetic oil or diphenyl ether synthetic oil, a diurea thickening agent, and an organic antimony compound or an organic molybdenum compound. The present invention is also directed to a rolling bearing in which the grease for a rolling bearing is sealed. The organic antimony compound or the organic molybdenum compound reacts with a metal composing inner and outer bearing rings and a rolling element to form a compound film contributing to the reduction of the force in the tangential direction on a raceway surface of the bearing rings and a surface of the rolling element, thereby preventing an excessively large force in the tangential direction under high-speed rotation. This enables to lengthen the life of the rolling bearing used under particularly severe conditions such as high temperature, high-speed rotation and high road.Type: GrantFiled: June 19, 1997Date of Patent: August 13, 2002Assignees: Koyo Seiko Co., Ltd., Nippon Grease Co., Ltd.Inventors: Hiroshi Komiya, Toshikazu Kouno, Masayuki Kitamura, Toshihiro Kawaguchi, Seiji Okamura, Hiroki Iwamatsu
