摘要： A multi-speed transmission includes a first power transmission module driven by an input shaft. A second power transmission module is driven by the first power transmission module. A third power transmission module is driven by the second power transmission module and drives an output shaft. Each power transmission module includes an actuation mechanism and a planetary gearset. Each actuation mechanism controls the output of its respective planetary gearset to one of a first gear ratio and a second gear ratio. One of the actuation mechanisms includes a clutch and a spring biasing a member to rotate and cause a corresponding actuation of the clutch. The clutch causes two members of the respective planetary gearset to rotate at substantially the same speed and provide the first gear ratio. The actuation mechanism selectively restricts the member from rotating and prevent actuation of the clutch to provide the second gear ratio.

摘要： A hybrid transmission providing multiple modes of operation in a compact arrangement is provided and includes first and second planetary gear sets and first and second electric machines. An electric machine shaft directly couples the first planetary gear set to the second planetary gear set and the second electric machine to the second planetary gear set. The second electric machine is selectively directly coupled to an output shaft via a first clutch mechanism, and indirectly coupled to the output shaft via the second planetary gear set and a drive shaft, which extends parallel to the electric machine shaft and external to the second electric machine. A second clutch mechanism selectively couples the first electric machine to a carrier of the second planetary gear set and a third clutch mechanism selectively couples a ring gear of the second planetary gear set to a hybrid drive unit housing.
