Abstract:

A manual two-speed automotive transmission adapted to being driven by an electric motor. The transmission includes an input shaft assembly driven by the motor via its armature, a flywheel and a clutch, an input gear assembly axially aligned with and separated from the input shaft assembly, and a transfer shaft assembly parallel to the input assemblies. A two-gear speed reducer rotatably mounted on the transfer shaft assembly connects a fixed gear of the input shaft assembly to a fixed gear of the input gear assembly. Additional gears are rotatably mounted on the transfer shaft assembly and secured to the input gear assembly, such that a synchronizer assembly on the transfer shaft cooperates with the various gears to drive the transfer shaft and a final output gear mounted thereon at a low or high speed. Reverse is accomplished by reversing the electric motor.
