A suspension assembly couples a wheel assembly (16) and a brake assembly (60) to a frame (10). The suspension assembly includes a support (20) for receiving an axle (24). The axle carries the wheel assembly (16) at one end of the support (20) and forms a drum (46) at the other end of the support (20) for engagement with the brake assembly (60). Therefore, the support (20) separates the wheel assembly (16) from the brake assembly (60) so that the brake assembly (60) brakes the wheel assembly (16) via the axle (24).
