Camber adjustemnt device

A camber adjustment assembly for adjusting the camber of a wheel in a vehicle suspension system of the type ordinarily including 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 hole therein adapted to closely, axially slidingly receive a first bolt therein which also passes through a first pair of coaxially aligned holes in the strut flanges in close axially sliding relationship and with a second hole therein adapted to closely, axially slidingly receive a second bolt which also passes through a second pair of coaxially aligned holes in the strut flanges in close axially sliding relationship, 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 first and second pair of holes in the strut flanges having axes positioned in substantially perpendicular relationship with the axis of rotation of a wheel supported on the wheel knuckle assembly, the camber adjustment assembly comprising:
• (a) parallel laterally extending slot means provided in said pair of strut flanges by lateral extension of said first pair of holes therein;
• (b) cam bolt means having a central longitudinal axis for providing adjustable pivotal movement of said wheel knuckle about said axis of said second hole in said wheel knuckle mounting portion, said cam bolt means being received in said parallel slot means in said strut flanges and in said first hole in said wheel knuckle with said central longitudinal axis thereof positioned coaxially with said axis of said first hole in said wheel knuckle assembly and being adjustably laterally movable in said parallel slot means in a first relatively loosened state of said cam bolt means and being relatively fixed with respect to said parallel slot means in a second relatively tightened state of said cam bolt means;
• (c) cam plate means mounted on at least one of said strut flanges and adapted to coact with said strut flange and said cam bolt for causing said relative lateral displacement of said cam bolt in said strut flange parallel slot means during rotational movement of said cam bolt means about said cam bolt means central longitudinal axis in said first relatively loosened state;
• (d) whereby the camber of a wheel mounted on said wheel knuckle assembly is adjustable through rotation of said cam bolt means about said cam bolt means central longitudinal axis.
