Abstract
A fore-aft self-balancing personal transportation device having a single wheel structure with multiple air chambers and air pressure equalization between the air chambers. Embodiments include dual tires on a single rim structure, or a single tire structure with multiple lobes, etc. Air passage between the air chambers may be internal through the rim or external via an air hose or related structure. The air chambers may be tubed or tubeless. Several different embodiments are disclosed.
Claims22
A personal transportation device, comprising:
- a single wheel structure having a rim structure and first and second air chamber defining members, respectively defining first and second air chambers, mounted to the rim structure;
- first and second foot supports provided on opposite sides of the wheel structure;
- a drive motor that drives the wheel structure;
- a positioning sensor that determines fore-aft position;
- and
- electronic control circuitry that causes the drive motor to drive the wheel structure towards fore-aft self-balancing based on position data from the position sensor;
- wherein the device is configured such that air passes between the first air chamber and the second air chamber.
