Patent number: 9021907Abstract: A housing slidably guides a slider, which is driven in response to selection of a shift range of an automatic transmission. Upper and lateral sides of a movable range of the slider are covered with the housing. Thereby, application of hydraulic fluid and foreign objects to guide rails is limited to limit malfunction of the slider. Furthermore, even when the hydraulic fluid and foreign objects adhere to the guide rails, the hydraulic fluid and foreign objects can be collected at ends of the movable range of the slider and can be expelled to an outside of the housing through open ends of the housing.Type: GrantFiled: June 29, 2011Date of Patent: May 5, 2015Assignees: Denso Corporation, Mazda Motor CorporationInventors: Akira Takagi, Mikio Kanefusa, Shigeki Hirakawa, Takahiro Kimura, Akihiro Mitani, Shotaro Nagai, Keiichiro Sueshige, Takenori Kawano

Patent number: 8733210Abstract: There is provided, in one aspect of the present description, an automatic transmission. In one example, the automatic transmission comprises a transmission case, a valve body which is arranged in the transmission case, a control valve mechanism which controls oil pressures in parts of the automatic transmission and is installed in the valve body, and a solenoid valve which is attached to the valve body and is arranged at a first side of the valve body and in the transmission case. The automatic transmission further comprises an electronic control unit which controls the solenoid valve, is attached to the valve body, and is arranged at a second side of the valve body that is opposite to the first side across the valve body.Type: GrantFiled: November 2, 2010Date of Patent: May 27, 2014Assignee: Mazda Motor CorporationInventors: Keiichiro Sueshige, Akihiro Mitani, Tatsutoshi Mizobe, Shotaro Nagai, Takenori Kawano, Takahiro Kimura

Patent number: 8210975Abstract: An automatic transmission is provided. One embodiment of the automatic transmission may include a valve body including control valves for hydraulically controlling a friction engaging element provided within said transmission. The automatic transmission may further include an electric control unit located on said valve body for controlling gear shifting of said automatic transmission. The automatic transmission may further include a transmission case having a peripheral wall for at least partially enclosing a gear shift mechanism and an outer wall provided adjacent to said peripheral wall, wherein said electric control unit is located within a containing space surrounded by said peripheral wall, said outer wall and said valve body.Type: GrantFiled: August 27, 2008Date of Patent: July 3, 2012Assignee: Mazda Motor CorporationInventors: Tatsutoshi Mizobe, Junichi Doi, Shinya Kamada, Keiichiro Sueshige, Akihiro Mitani
