Patent ID: 7434823

Claim:
A suspension arrangement for a wheel of a vehicle comprising: upper and lower links of equal pivotal length displaced from each other and rotatably attached to a chassis or body of the vehicle at first ends to respective upper and lower chassis attachment points separated by a first spacing; and an axle support link locating a wheel axle at an axle end of the axle support link and attached at a link end of the axle support link to second ends of the upper and lower links by link attachment points separated by a second spacing, in which the first spacing is double the second spacing, and a centre distance between the wheel axle and each of the link attachment points is the same as the length of the upper and lower links, such that the geometry of said arrangement constrains movement of the axle and wheel rectilinearly between the chassis attachment points and the angular displacement of the axle support link focuses to an axis or centre point exhibiting rectilinear displacement at 90° to that of the wheel.
