发明名称 Personal transporter having multiple independent wheel drive
摘要 A multiple wheel drive personal transporter includes a lightweight skeletal frame based on a single cylindrical fore-aft beam to which front and rear axle, motor drive and wheel assemblies are connected. Each wheel is driven by a battery powered electrical motor and transmission gear sprocket chain drive. All wheels, or by user control option just front wheels, are powered on in parallel and energized by PWM drive circuitry. Throttle, forward/reverse, steering and other controls are available on a single flight stick. The seat is mounted over the beam near the rear, with front and rear battery trays and the user's weight distributed for optimum stability and traction and the beam is made of telescoped tubular sections incorporating a seat tilt limiting differential that responds to differential rotation of the front and rear wheel assemblies as the transporter traverses uneven ground.
