Abstract
Abstract A novel transmission is provided for use with a vehicle having a drive train and an engine with a rotary drive output shaft. The transmission comprises a housing having a driven member rotatably mounted to the housing and the driven member is coupled to the engine drive shaft. A drive member is also rotatably mounted to the transmission housing and is adapted for connection to the vehicle drive train so that rotation of the drive member in one direction propels the vehicle forwardly while the opposite rotation of the drive member propels the vehicle in reverse. A plurality of coupling members including at least one annulus are contained within the housing and selectively couple the driven member to the drive member in different gearing ratios in order to propel the vehicle. In addition, the annulus is driven by the engine in a predetermined direction of rotation. An electric motor is selectively coupled to the annulus to rotatably drive the annulus in the opposite direction and thereby propel the vehicle rearwardly.
