Patent number: 5026337Abstract: A ring gear of a dual planetary gear, or a big ring gear is fixed on a peripheral section of a disc type supporting member, and both sides of the supporting member are supported by thrust bearings situated in small radius section of the supporting member. The ring gear of the planetary gear unit is fixed on the peripheral section of the disc type supporting member. The supporting member is held and supported between a side of a carrier of the planetary gear unit and a boss section on a counter gear through thrust bearings. The ring gear rotates when an automatic transmission operates. Then the supporting member also rotates, but the bearings are situated at a portion where rotative speed is low, so that the bearings receive thrust force based on the low speed rotation. The supporting member has a groove and a step-like section to set the bearings.Type: GrantFiled: January 23, 1989Date of Patent: June 25, 1991Assignee: Aisin AW Co., Ltd.Inventors: Masakatsu Miura, Masahiko Ando

Patent number: 4942782Abstract: A reverse shift control device of an automatic transmission prevents reverse running of the automatic transmission, even though a manual shift lever is set to a reverse range, when the vehicle runs at more than a predetermined speed. Certain shift valves have ports to which line pressure is applied from the manual valve when set to reverse, and also have ports which communicate with a hydraulic servo of a frictional engaging component which is engaged when the vehicle travels in reverse. When the manual valve is set to reverse and the vehicle speed is more than a predetermined speed (for example, 7 km/h), respective pairs of the ports are disconnected due to the shifting of the shift valves based on the signal issued by a controller.Type: GrantFiled: March 1, 1988Date of Patent: July 24, 1990Assignee: Aisin-Warner Kabushiki KaishaInventors: Yoshinari Kuwayama, Fumitomo Yokoyama, Masakatsu Miura

Patent number: 4916977Abstract: Automatic transmission including a main-transmission-mechanism consisting of two planetary gear units (three speed or four speed transmission mechanism for example) and a sub-transmission-mechanism consisting of one planetary gear unit (underdrive mechanism, for example). One speed and two speed for the whole transmission are obtained, with a low speed stage of the main-transmission-mechanism lower than two speed, by shifting the main-transmission-mechanism to one and two speed, respectively, while the sub-transmission-mechanism is kept at low speed (underdrive). And three speed for the whole transmission is obtained by shifting the sub-transmission-mechanism to high speed (direct coupling) while the main-transmission-mechanism is left at the two speed state. Further, four speed or five speed for the whole is obtained by shifting the main-transmission-mechanism to three speed or, if it is of four speed type, to four speed, respectively, while the sub-transmission-mechanism is kept at the high speed state.Type: GrantFiled: August 6, 1987Date of Patent: April 17, 1990Assignee: Aisin-Warner Kabushiki KaishaInventors: Hideyuki Aoki, Masakatsu Miura
