Centreless Hollow Wheel Drive System
A drive unit consists of an electrically powered motor connected to a right-angle drive into the centreless wheel. The drive unit is placed within the chassis to allow for steering and suspension. Within the hollow part of the wheel is fitted an electrically driven lift rotor. Because of advancement of technologies the steering, suspension, braking (ALL ELECTRIC) etc. can all be within the drive system therefore no conventional engine required – 4 drive-systems per vehicle.
