Patent number: 9068645Abstract: A method of controlling a level of fluid in a main sump of a transmission includes opening an auxiliary reservoir with a first valve when fluid temperature in the main sump is at or below the predetermined temperature. The first valve is opened to increase the level of fluid in the main sump to at least a predetermined height so that transmission rotating components contact the fluid and generate splash lubrication. When the transmission is transmitting torque and the fluid is above the predetermined temperature, the level of fluid in the main sump is maintained below a predetermined height with closed first valve, such that the rotating components do not contact the fluid inside the main sump. A fluid pump alone is sufficient to lubricate the rotating components above the predetermined temperature and sufficient to lubricate the rotating components at or below the predetermined temperature only with splash lubrication.Type: GrantFiled: February 15, 2013Date of Patent: June 30, 2015Assignee: GM Global Technology Operations LLCInventors: Goro Tamai, Norman Schoenek, Anthony J.

Electrically actuated rotating band torque transmitting mechanism for hybrid and other transmissions
Patent number: 9062719Abstract: A torque transmitting mechanism includes a drum attached to one of a first member and a second member, and a shell attached to another of the first member and the second member. The drum and the shell are concentrically disposed about a longitudinal axis, with the shell concentrically disposed about the drum. An electric motor includes a stator, and a first rotor rotatable about the longitudinal axis relative to the stator. A band is coupled to the shell, wrapped around the drum between four and twelve complete revolutions, and includes a first end attached to the first rotor for rotation with the first rotor. The band includes a second end attached to a reaction member. Rotation of the first rotor tightens the band against the drum to bias the drum against the shell, to transmit torque between the first member and the second member.Type: GrantFiled: July 11, 2013Date of Patent: June 23, 2015Assignee: GM Global Technology Operations LLCInventors: Alan G.
