Camber adjustment device with finite camber adjustment settings

Claim 1

A camber adjustable, vehicle wheel suspension system comprising: a generally vertically extending strut assembly having an upper end attached to a vehicle frame assembly and having a pair of strut flanges positioned in parallel relationship with one another and projecting laterally outwardly from a lower end portion of the strut assembly; a wheel knuckle assembly mounted on the strut assembly and having a mounting portion positioned between the two strut flanges with a first bolt hole therein adapted to closely, axially slidingly receive a first bolt therein which is also laterally displaceably received in a pair of oppositely positioned, laterally extending slots in the two strut flanges and with a second bolt hole therein adapted to closely, axially slidingly receive a second bolt which also passes through a pair of coaxially aligned bolt holes in the strut flanges, the first and second holes in the wheel knuckle mounting portion being vertically spaced apart, the first and second bolt holes in the wheel knuckle mounting portion and the pair of slots and pair of holes in the strut flanges having axes positioned in transverse relationship with the axis of rotation of a wheel supported on the wheel knuckle assembly; cam plate means for stably holding said first bolt in a plurality of discrete, relatively laterally shifted positions within said slots; a different wheel camber position being provided by each of said discrete, relatively laterally shifted positions of said first bolt; said cam plate means comprising a discrete peripheral surface portion associated with each of said plurality of different wheel camber positions; said cam plate means being mounted in freely rotatable radially nondisplaceable relationship relative said first bolt central longitudinal axis; cam engaging means stationarily mounted on one of said strut flanges for selectively engaging different ones of said discrete peripheral surface portions of said cam plate means for preventing slipping rotation of said cam plate means about said first bolt central longitudinal axis and for holding said cam plate means at a fixed lateral location relative said strut flange slots, which is associated with the selected one of said can means peripheral surface portions engaged by cam engaging means; said cam engaging means comprising a reaction plate which is adapted to be secured to said one of said strut flanges by said first bolt; said reaction plate comprising a cam engaging portion adapted to engage said cam plate means and further comprising a lateral stabilizing means for preventing relative lateral movement of said reaction plate relative said laterally extending slot in said strut flange.
