Abstract
A propulsion system for a manual wheelchair includes a mounting clamp and a propulsion drive unit having a drive wheel assembly and a support suspension. The support suspension is configured to provide linear movement of the drive wheel and drive hub assembly relative to the manual wheelchair. The support suspension includes a linear bearing and slide member assembly having at least one linear bearing and a slide member for accommodating the linear movement of the drive wheel assembly and further includes a resilient suspension member that provides a tractive effort force to the drive wheel. The drive wheel assembly is supported on a carriage that is attached to one of the at least one linear bearing or the slide member and a mounting block is attached to the other. The mounting block has a clamp interface with a locating tab that engages a corresponding mounting slot in the mounting clamp.
