ABSTRACT:
A power transfer system including a variable speed electric motor and a single speed transmission is disclosed for transferring power from a source of power to a pair of driven wheels. This arrangement is particularly adapted for use in electric vehicles incorporating a high speed electric motor. In a preferred embodiment, the single speed transmission includes a housing, an input shaft for receiving drive torque from the electric motor, at least one output shaft and an intermediate shaft supported for rotation of the housing between the input shaft and the output shaft. The single speed transmission further includes a parking sprag arrangement for preventing rotation of the output shaft when a park mode is selected. In one embodiment, the single speed transmission further includes a transfer mechanism for selectively transmitting the source of drive torque from the input shaft to the output shaft which includes a shift member movable between a first position for preventing relative rotation between the input shaft and the output shaft and a second position for establishing relative rotation between the input shaft and output shaft.
