Patent number: 8387665Abstract: A compact fluid accumulator both stores a relatively large amount of fluid and provides good fluid pressure stability. The accumulator includes a piston slidably disposed in a cylinder having a fluid inlet/outlet at one end which communicates with a first chamber and one face of the piston. Engaging the opposite face of the piston, and disposed in a second chamber, is a compression spring. The second chamber is filled with a gas which is at atmospheric pressure when the accumulator is relaxed. When pressurized hydraulic fluid fills the first chamber, the piston moves against the pressure of the spring and gas in the second chamber. The present invention thus provides an accumulator having the relatively small size of a gas filled accumulator without the leakage problem of a super-atmospheric gas charge—the extra force being provided by the compression spring.Type: GrantFiled: December 10, 2009Date of Patent: March 5, 2013Assignee: GM Global Technology Operations LLCInventors: Philip C. Lundberg, James B. Borgerson

Patent number: 8388485Abstract: A multispeed automatic transmission is provided having four planetary gear sets, a plurality of friction and synchronizer clutches and two chain drive assemblies. The transmission is arranged along two parallel axes of rotation: a first axis defined by the input shaft and a second axis defined by the output shaft. The chain drive assemblies transfer power between sprockets disposed on the two axes. Various combinations of clutches may be engaged to provide nine forward speed ratios and five reverse speed ratios.Type: GrantFiled: February 13, 2012Date of Patent: March 5, 2013Assignee: GM Global Technology Operations LLCInventors: Andrew W.

Patent number: 8375710Abstract: A hydraulic control system for a powertrain includes a sump for storing a hydraulic fluid and a pump having an inlet in communication with the sump and an outlet. A valve system is in communication with the outlet of the pump. An accumulator for storing and releasing the hydraulic fluid is in communication with the inlet of the pump and with the valve system. A first control device is disposed between the accumulator and the valve system. A second control device is disposed between the accumulator and the inlet of the pump. The accumulator is charged with the hydraulic fluid when the pump is powered, the accumulator stores the hydraulic fluid when the first control device and the second control device are in the closed condition, and the accumulator releases the hydraulic fluid and primes the pump when the second control device is in the open condition.Type: GrantFiled: July 20, 2009Date of Patent: February 19, 2013Assignee: GM Global Technology Operations LLCInventors: Edward W.

Patent number: 8342996Abstract: Various embodiments of electrically-variable transmissions are provided that have two motor-generators, two planetary gear sets, and two torque-transmitting mechanisms, including a rotating-type clutch and a stationary-type clutch. An input member is connected for common rotation with a ring gear of the first planetary gear set. Carriers of both of the planetary gear sets are connected for common rotation with one another, and with an output member. The first motor/generator is connected for common rotation with the sun gear of the first planetary gear set. The second motor/generator is connected for common rotation with the sun gear of the second planetary gear set. A drive transfer assembly transfers torque from components establishing the first axis of rotation through components establishing one or two additional axes of rotation to a differential establishing yet another axis of rotation.Type: GrantFiled: July 22, 2009Date of Patent: January 1, 2013Assignee: GM Global Technology Operations LLCInventors: Edwin T.
