Abstract: A two-speed transmission for an electric vehicle includes a planetary gear set selectively coupling an input shaft and an output shaft. The planetary gear set is configured to provide two forward gear ratios and neutral. The planetary gear set includes at least one sun gear, at least one pinion in meshing engagement with the at least one sun gear, at least one ring gear meshingly engaged with the at least one pinion, and a carrier. The carrier supports the at least one pinion and is connected to the output shaft such that rotation of the carrier drives the output shaft. The two-speed transmission also includes one or more elements that rotatably couple the at least sun gear, the at least one pinion, the at least one ring gear, the input shaft, and the carrier with one another and/or a ground. Examples of such elements include clutches, brakes, and mechanical diodes.

Abstract: A torque converter for coupling an engine to a manual transmission and a method of controlling the same are provided. The torque converter includes a housing rotating with the engine, a cover abutting the housing, a stator, a pump circulating fluid within the torque converter, and a turbine driven by the circulating fluid. An integrated disconnect clutch controls pump speed and a torsional damper attenuates vibrations transmitted through the housing. A first output shaft is coupled with the turbine and drives a first forward gear of the manual transmission while permitting slip. A second output shaft is coupled with the torsional damper, the integrated disconnect clutch, and the pump and drives at least one other forward gear of the manual transmission without slip. An output connection member rotatably couples the pump with the torsional damper, the integrated disconnect clutch, and the second output shaft.
