ABSTRACT:
A drive system for an electric vehicle, which can make the number of parts as small as possible and minimize the space for arranging the parts in a direction perpendicular to the axis. Between a motor acting as a prime mover and left and right output shafts, there are interposed toroidal type continuously variable transmissions which can individually control their gear ratios and their forces for thrusting power rollers. The RPMs and torques of left and right wheels can be individually controlled, and the differential rotation between the left and right wheels can be smoothly established by the continuously variable transmissions.
