Abstract
Abstract Independently mounted wheel supports on opposite sides of a vehicle are each mounted by a pair of upper and lower links. Corresponding main links of each pair are pivoted on a single common axis on the vehicle. The other link of each pair is pivoted to the main link of the opposite pair, at a point vertically displaced from said common axis, to hold the wheels parallel and coaxial at all times with their camber unaffected by lateral forces on the vehicle. The system is equally applicable to steerable or driven wheels.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
A vehicle wheel suspension system for a vehicle having a frame, comprising: wheel-mounting members on opposite sides of said frame and having wheel-mounting axle means thereon; pairs of upper and lower links having their outer ends pivoted, respectively, to upper and lower portions of said mounting members, about generally fore-and-aft axes, one of said upper and lower links of each pair comprising a major link; each of said major links being mounted to said frame for pivotal movement about a common fore-and-aft major axis fixed relative to said frame generally centrally thereof; each of said major links having pivot-defining means fixed thereon, vertically displaced from said major axis; and, each of the other of said links of each pair being pivoted at its inner end to the pivot defining means on the major link of the other pair.
