ABSTRACT:
Apparatus comprising a part of a shock absorbing wheel suspension system of a motorcycle sidecar which is adjustable for securing the sidecar wheel at both different toe-in positions and offset positions. The suspension system includes an elongate swing arm that is pivotally secured to the sidecar frame at one end and carries the wheel assembly at its other end. In one embodiment, the swing arm comprises two elongate members that may be secured together at different relative angular positions corresponding to different sidecar wheel toe-in positions. Means are also provided so that the wheel-carrying one of the two members may be secured at different locations along the length of the other elongate member corresponding to different wheel offset positions. The means provided for securing the members together at different angular positions also functions to secure them together at different relative longitudinal positions. In another embodiment, the apparatus for adjusting the toe-in includes means for securing a swing arm pivot axle to the sidecar frame at different relative angular positions corresponding to the different wheel toe-in positions.
