ABSTRACT:
A modular vehicle includes a frame having three main sections; a front section, a rear section and a center section. The front and rear sections may be displaced vertically with respect to center section prior to being assembled. Each section is separately assembled and standardized so that various devices may be incorporated to each section and each section may be otherwise modified to allow a specific vehicle to be easily and quickly manufactured.
Another aspect of the invention is a drive assembly that includes at least two electric motors, each having different operating characteristics. Each motor is connected to a common drive shaft through a controllable clutch. A drive system controller selectively activates each motor in response to power demand, as determined by a relative position of an accelerator pedal, by engaging the clutch of a selected motor and simultaneously providing power to the selected motor.
Another aspect of the invention is a quick-release wheel assembly that includes a rim having an inner wall which defines an adjacent central opening. The opening is sized and shaped to snugly receive a cylindrical hub so that the inner wall lies flush to an outer wall surface of the hub. Radially directed pins are positionable through both inner wall and outer wall surface of the hub so that the wheel may be selectively engaged to the hub.
