Abstract
An assembly for use with an electric motor, including a shaft with on a first end and on a second end a rotatable gear. Each gear is fixedly connected to a first clutch member that can slipping engage a second clutch member extending around the shaft and connected to the shaft in a fixed angular position. A force member is axially situated between the clutch members for moving second clutch members relative to the first clutch members in an axial direction such that the first clutch members and the second clutch members can engage and disengage in a slipping manner at relative circumferential speeds.
