Abstract
Abstract The hydraulic strut assembly and the wheel support knuckle of a vehicle strut type suspension are mounted in the vehicle such that the vehicle sprung mass imposes a force couple tending to drive the suspension parts toward a maximum negative camber position, and an adjustable set screw device is threadably mounted in the knuckle to abut the strut lower end and oppose the force couple to hold a selected camber position.

Claim 1
Independent Claim
350 words
In a vehicle wheel suspension including a wheel support means, a wheel thereon, a strut arranged on a generally upright axis and connected at its upper end to the vehicle sprung mass and at its lower end adapted for connection to the wheel support means, and a lateral arm member swingably mounted at an inner end on the sprung mass and connected at its outboard end by joint means to a lower end of the wheel support means, the improvement which comprises, said axis of said strut being so disposed relative to the median vertical plane of said wheel as to create a force couple urging the top of said wheel inboard of the vehicle sprung mass, a pair of bracket walls on said strut lower end and including upper and lower sets of horizontally aligned bolt holes, a portion of said wheel support means received between said bracket walls and including upper and lower bolt-receiving apertures each registered in combination with a corresponding said set of bolt holes, bolt fasteners extending through each said bolt hole sets and registered apertures, one of said aperture or bolt hole set of one of said bolt hole set and registered aperture combinations being of enlarged size in direction inboard and outboard the vehicle sprung mass relative the size of said bolt fastener to permit a limited range of relative movement between said strut lower end and said wheel support portion for wheel camber adjustment, and a set screw otherwise unconstrained but threadedly mounted in one of said wheel support portion or strut lower end adjacent said enlarged aperture or bolt hole set and extending transversely of the vehicle sprung mass, said set screw having its inboard end exposed to be abutted under the urging of said force couple against the other of said strut lower end and wheel support portion whereby to provide thereat a physical stop resisting said force couple, said set screw being threadable transversely to locate said wheel support means at a selected camber setting within the range of movement permitted by said enlarged aperture or bolt hole set.
