ABSTRACT:
A clutch mechanism includes a housing adapted to be rotated by an automotive engine, a shaft having first and second sections and a first end adapted to be an input to a transmission, and first and second clutch devices positioned with the housing. The first clutch device, which includes a planetary gear set, can be connected to the first section of the shaft to rotate the shaft. The second clutch device can be connected to the second section of the shaft to rotate the shaft. The planetary gear set provides a gear splitting system for use in doubling the number of gear ratios supplied by the transmission.
