Abstract:
A one mode, front wheel drive continuously variable transmission includes a transmission input member interconnected to an engine of the motor vehicle, a transmission output member, a continuously variable unit having a first pulley pair, a second pulley pair, and a chain wrapped around the first pulley pair and the second pulley pair. A planetary gear set includes a first member, a second member, and a third member. The first member is connected to the first pulley pair and the third member is connected to the transmission input member. A clutch is selectively engageable to connect the first member of the planetary gear set with the transmission input member. A band brake selectively engageable to connect the second member with a stationary member. The transmission output member is interconnected to a differential supported by sets of ball bearings.

Abstract:
A transmission assembly for use in a motor vehicle is provided. The transmission assembly has a case for housing components of the transmission and an electromechanical device operable to convert mechanical energy to electrical energy. The electromechanical device is disposed within the transmission case. The case may have a main housing portion and a bell housing portion, with the electromechanical device housed in the main housing portion, in some variations. A transmission shaft may be rotatably supported within the case and configured to be connected to an engine of the motor vehicle. A connecting device may continuously interconnect the electromechanical device with the transmission shaft.
