Abstract

Disclosed is an improved variable speed transmission system adapted for, in particular, an electrically powered vehicle. The system is operated by a common manual gear shift.
The manual gear shift has a power source made up of a specially designed electric motor having a rotatable outer shell which is relatively moveable with respect to a core rotor so that the power from the rotatable outer shell and from the core rotor of the electric motor can be output respectively to front and a rear differential gear devices, and the vehicle can be powered to move via the differential gear devices. Respective transmission shafts between the electric motor and the front and rear differential gear devices can be selectively locked so that the power from the motor to the differential gear devices can be selectively varied so that the rotational speed of the wheels of the automobile can be varied.
