ABSTRACT:
A tracked vehicle (10) propelled by a pair of direct current electric motors (35) operating through a power train to a pair of endless tracks (11). Each power train operates a track drive sprocket (14) through a state of the art torque hub. Electric energy is applied to the motors from a battery pack (13) carried by the vehicle, acting in conjunction with a power control and distribution unit which directs the electrical energy from the batteries as needed. Braking of forward motion of the vehicle is accomplished in part by regenerative use of the motors, each as a generator feeding electricity back to the battery pack and consequently braking the vehicle's motion by the resistance of rotation of the armature rotor.
