Abstract:
The present device is an integrated automotive wheel for electric vehicles which substantially reduces energy loss due to tire flex and energy loss from a conventional drive train. The wheel includes an axle, a hub, two composite sidewalls, a low pressure inner chamber with shock absorbing hub protector, and at least one outer high pressure pneumatic chamber with tread. The hub can contain an electric hub motor which rotates the wheel, propelling the vehicle. The sidewalls include at least one pressurized chamber which position the outer tread ring and enable the wheel to simulate an energy efficient high pressure pneumatic wheel, experiencing little deformation when under smooth road conditions. When road conditions are rough, the sidewalls can temporarily buckle in response to the increased road forces, simulating a low pressure conventional tire having ample space for deformation, with suspension and shock absorption capability built in. The sidewalls and outer ring chamber can be filled with high pressure closed cell foam to prevent flats.
