ABSTRACT:
A drive mechanism for a lever propulsion wheelchair includes at least one clutch and at least one gear set contained within a central hub housing operatively coupled to the drive surface of the main wheel being driven. In the preferred embodiment, there are additional clutches and gear sets contained within the hub housing and coaxial to the wheel. By locating the transmission components within the hub housing and providing the coaxial arrangement, various user capabilities may be enabled without a significant increase in wheelchair width, as compared to the width of conventional pushrim propulsion wheelchairs. Transmission components are cooperatively arranged to provide capabilities that may include forward, rearward and neutral “gears,” braking, anti-rollback, and quick-release removal.
