Abstract

An electric vehicle which has motor wheels of the direct-drive outer-rotor type which permit simplification and compaction of the motor wheels. Current regulating covers introduce ambient air for cooling the motors and reduce air resistance, and batteries and control devices are disposed symmetrically relative to the axial line of the vehicle body and to axial lines of the axles so as to reduce and uniformly distribute the weight of the vehicle. All these devices contribute jointly to increasing the range of the electric vehicle.
