Patent number: 8388479Abstract: An automatic transmission having an improved lock up torque converter configuration includes two drive members: a first quill or tubular drive member which carries the output of the torque converter to the transmission gearbox and a second co-axial shaft or drive member which is driven by the torque converter lockup clutch and thus directly carries the engine output to the transmission gear box and bypasses the torque converter. The transmission gearbox includes two planetary gear assemblies having certain elements which are selectively grounded to the transmission housing by two friction brakes. This transmission, torque converter and torque converter clutch configuration prevents torque converter clutch engagement in its lower gear and forces torque converter clutch lockup in its upper gear.Type: GrantFiled: April 28, 2011Date of Patent: March 5, 2013Assignee: GM Global Technology Operations LLCInventors: Andrew W. Phillips, Donald L. Dusenberry

Patent number: 7992695Abstract: A selectable one-way clutch (SOWC) assembly uses hydraulic-actuation to select operating modes within a rotating housing. Two races of the SOWC assembly can rotate at disparate speeds, i.e., one race is not grounded prior to actuation. The SOWC assembly has a pair of races keyed to different housings and hubs. The housing and hub can be attached to different elements of a gear train, for example, which can be rotating during the various gear states. A hydraulic actuator or multiple actuators can be keyed to the housing, with axial motion of the actuator or actuators selecting a state or operating mode of the SOWC assembly. The actuator has axially-extending tabs that engage radially-extending fingers of the selector plate, thus rotating the selector plate in different directions when applied or released. Multiple actuators can be used in conjunction with multiple selector plates to provide additional SOWC operating modes.Type: GrantFiled: December 8, 2008Date of Patent: August 9, 2011Assignee: GM Global Technology Operations LLCInventors: Scott H.
