Patent number: 8678780Abstract: A system for providing pressurized hydraulic fluid in a transmission of a motor vehicle includes a pump for providing pressurized hydraulic fluid having an inlet port and an outlet port. A bypass valve includes an inlet port in communication with the outlet port of the pump, a first outlet port in communication with the inlet port of the pump, and a second outlet port. The inlet port of the bypass valve is in communication with the second outlet port of the bypass valve when the bypass valve is in a first position and the inlet port of the bypass valve is in communication with the first outlet port of the bypass valve when the bypass valve is in a second position. A control device and accumulator are operatively associated with the bypass valve.Type: GrantFiled: February 26, 2010Date of Patent: March 25, 2014Assignee: GM Global Technology Operations LLCInventors: Kevin Michael Dougan, Fredrick R. Poskie, Edwin T. Grochowski, Bret M. Olson, James W. Haynes

Patent number: 8677852Abstract: A multiplexed electromechanical shift mechanism includes a single linear actuator with multiple independently selectable linkages actuating a clutch and multiple gears for use in motor vehicle transmissions such as a dual clutch transmission. The linear actuator may be a ball screw, a planetary roller screw or hydraulic or pneumatic operator capable of controlling bi-directional linear motion of an output member. A plurality of linear clutches selectively couple the output member to one of a plurality of linkages adapted to transfer the bi-directional motion of the output member. One of the linkages is coupled to and engages an input (main) clutch of the transmission and the remaining linkages are coupled to and bi-directionally translate shift forks and synchronizer clutches which achieve gear selection and engagement.Type: GrantFiled: February 23, 2010Date of Patent: March 25, 2014Assignee: GM Global Technology Operations LLCInventors: Vijay A. Neelakantan, Bret M. Olson, James W. Haynes, Clinton E. Carey

Patent number: 8328674Abstract: A hybrid powertrain for a vehicle is provided with a motor/generator for providing torque to a final drive input member. The powertrain includes an engine, a transmission having a transmission input member configured to receive power from the engine and a transmission output member. The powertrain further includes a final drive arrangement that has a final drive input member, and a motor/generator that has a motor shaft operatively connected to the final drive input member downstream of the transmission gearing arrangement. A drive system may operatively connect the transmission output member and the motor shaft to the final drive input member. A method of assembling a hybrid powertrain is also provided.Type: GrantFiled: January 25, 2010Date of Patent: December 11, 2012Assignee: GM Global Technology Operations LLCInventors: Shawn H. Swales, Leonid Basin, Fredrick R. Poskie, James W. Haynes

Patent number: 7837590Abstract: A transmission assembly includes a clutch housing, a gear arrangement disposed within the clutch housing, and a fixed component. A brake having a housing and a hub is also included. The housing is coupled to the fixed component and the hub is coupled to the gear arrangement. The brake is disposed external to the clutch housing and cooperates with the gear arrangement to provide at least one forward or reverse gear ratio.Type: GrantFiled: March 12, 2007Date of Patent: November 23, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Fredrick R.

Patent number: 7695399Abstract: A planet carrier assembly has a plurality of pinion gears rotatably mounted on pinion pins, each pin having a slot formed thereon. A locator ring is assembled onto the pinion pins and rotated in a manner such that the locator ring engages the slots in the pinion pins and a plurality of tabs and protuberances engage complementary components formed on a housing member of the planet carrier assembly. The locator ring ensures both axial and rotational positioning of the pinion pins within the planet carrier housing.Type: GrantFiled: January 11, 2005Date of Patent: April 13, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Henryk Sowul, Anatoly Filanovsky, Michael B. Solt, Fredrick R. Poskie, James W. Haynes

Publication number: 20090078082Abstract: A transmission casing adapter ring is provided that enables a transmission having a common outer casing to be operatively connected to an engine, thus enabling different engines to be used with the common transmission outer casing simply by changing the adapter ring. The adapter ring allows a novel method of assembling a powertrain that permits assembly of the transmission with a generic (i.e., common) type of casing prior to a determination of the engine type or types to be used with the transmission. The adapter ring is aluminum, the transmission case is magnesium, and the engine is cast iron.Type: ApplicationFiled: September 26, 2007Publication date: March 26, 2009Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Fredrick R.

Patent number: 7284313Abstract: A hybrid transmission including two electric motors and a plurality of planetary gear sets operatively connectable to the motors and to an engine is provided. Novel motor features are provided including structure adapted to improve reliability and to facilitate assembly. More precisely, a method is provided for locating and installing the components of a motor, including a rotor and a stator, within a covered housing to form a motor module. A plurality of rotor bearings and a position/speed sensor are also preferably added to the motor module. After the motor module is assembled, the motor may be tested and thereafter the motor module can be installed into a hybrid transmission as a single component utilizing conventional transmission assembly methods.Type: GrantFiled: February 18, 2005Date of Patent: October 23, 2007Assignees: General Motors Corporation, DaimlerChrysler AG, DaimlerChrysler CorporationInventors: James A.
