Publication number: 20100132504Abstract: The present invention provides a hybrid transmission with two motor/generators, one being “on-axis” and sharing an axis of rotation with an input and output shaft of the transmission, and another being “off-axis” with a distinct axis of rotation from that of the first motor/generator. The transmission is adapted for cooling and lubricating the off-axis motor/generator, and includes a case at least partially defining a manifold. A transmission cover is mounted to the case such that the off-axis motor/generator is retained therebetween. The transmission cover at least partially defines an oil passage. The manifold is adapted to transfer oil onto a bearing device so that the bearing device is lubricated. Oil is also transferred through the oil passage and onto a torque transfer device such that the torque transfer device is lubricated.Type: ApplicationFiled: February 8, 2010Publication date: June 3, 2010Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Kent A. Miller, Henryk Sowul

Publication number: 20090241714Abstract: The present invention provides a three position hydraulic piston assembly for a gear ratio change mechanism for a transmission exhibiting reduced gear shift noise. The three position hydraulic piston assembly includes a master piston and motion retarding assemblies that act near both travel limits of the master piston. The master piston includes symmetrical passageways that provide hydraulic fluid flow to small chambers at each end of the piston that are closed off as the piston approaches its travel limits. Hydraulic fluid trapped in the chambers decelerates the piston and is bled off through an orifice allowing the piston to reach its travel limit and quickly and quietly engage a gear ratio.Type: ApplicationFiled: March 26, 2008Publication date: October 1, 2009Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INCInventors: HENRYK SOWUL, TEJINDER SINGH, BRIAN W.
