Abstract: An independent suspension and drive system comprising a transverse power shaft mounted on a vehicle frame and having a differential connection with a power source; at least one pivot shaft mounted on the vehicle frame; at least one cantilevered swing- or trailing- or pivot arms mounted on each of the at least one pivot shafts; at least one drive wheel, one each mounted on each of the respective at least one pivot arms via respective axles; and at least one chain or belt or equivalent member operatively connecting power shaft driver sprockets to respective wheel driven sprockets; wherein the centerline of the power shaft is substantially coincident with the centerline of each of the at least one pivot shafts, and wherein the pivot shafts are independent of the power shaft.

Abstract: An improved electrically powered vehicle and associated method of the type having a mobile electrical storage device for providing electrical power electrically connected to a switching device, for selectively controlling the flow of electric power. The switching device is electrically connected to an electric motor. It selectively allows the flow of electrical power to the motor. The motor is mechanically connected to a belt type continuously variable transmission with the transmission mechanically connected to a drive wheel of the vehicle. It is improved by the motor, being of the direct current type, that is electrically connected to a continuously variable power supply control device responsive to an operator input. Further, the motor is mechanically connected to the continuously variable transmission, with the transmission adapted to respond to the rotational speed of the motor by varying in speed ratio.

Abstract: A belt drive differential with an output shaft, two planet sprockets rotatably mounted to a carrier to orbit in a circular path about a carrier axis coaxial with the output shaft, a first output sprocket attached to the output shaft, a second output sprocket coaxial with the output shaft, and a toothed power transmission belt connecting the sprockets.

Abstract: A chassis for a single seat dirigible electric battery-powered personal transportation vehicle is formed by a central elongated beam having a front end and a rear end. A wheeled drive mechanism is mounted on the rear end of the beam. A swivel seat is mounted on the frame in overlying relation to the drive mechanism. A front battery support frame is mounted on the front end of the beam. Spaced apart side plates secured to the front battery support frame support a wheel suspension and steering mechanism. Side battery support frames are mounted on the beam rearwardly adjacent the front battery support frame and extending rearwardly and outwardly from the beam. Batteries mounted in the battery support frames provide electric power to the vehicle and provide a counterbalance to the seat and drive mechanism.

Abstract: A belt and reinforcement for a V-block of a V-block belt is provided. The reinforcement has a generally U-shaped member with a lower beam member that interconnects diverging diagonal side members that each form a cantilevered portion. A means is provided in the cantilevered portion for retaining an upper beam member. The means is in the form of deformable sides that define a slot for receiving end portions of the upper beam member.

Abstract: A power transmission belt of the V-block type with polymeric portions that define frictional driving surfaces. Extended polymeric portions are oriented transversely to the belt and are deflected such that successive blocks are in pressing contact with each other.

Abstract: A sprocket wheel with a generally equilateral polygonal rim and a plurality of spaced axially aligned teeth extending from at least one side of the rim.
