ABSTRACT:
Drive wheel axle assemblies (34) and caster wheel assemblies (94) are mounted to a wheelchair frame (4). Each axle assembly includes an axle adjustment tube (40) secured to the frame and an axle housing (56), defining an axle bore (58), toollessly mounted to the axle adjustment tube at any of several rotary orientations to determine the camber of the drive wheel (36) mounted to the axle assembly. The front to rear position of the axle housing can also be adjusted in a toolless manner using a quick release pin (66). The height of the front end (10) of the frame is changed, to ensure that the caster wheel pivot axis (96) remains vertical, without tools by mounting a caster wheel (98) at various vertical positions within a caster spool housing (100) using a quick release pin (122).
