Abstract
An apparatus allows for the independent adjustment of caster and camber for vehicles utilizing MacPherson strut front suspensions. The apparatus has, in stacked arrangement, a fastener plate, a lower plate, and an upper plate. Camber adjustments are generally made by manipulation of the lower plate and caster adjustments are generally made by manipulation of the upper plate. The upper plate may be mounted in two different positions to allow for different camber adjustments, such as for competitive situations and non-competitive situations. The device utilizes a thrust bearing having a race in the upper face of the spring perch and an opposing race which mounts around the base of the bearing cup.
Claims20
An apparatus for adjusting caster and camber, the apparatus comprising:
- a fastener plate comprising a first face and a plurality of apertures for receiving threaded fastening members for attachment of the apparatus to a vehicle strut tower;
- a lower plate having a lower face thereof positioned adjacent the first face of the fastener plate with the threaded fastening members extending through the lower plate, the lower plate comprising a shaft housing depending from the lower face, the shaft housing having a bore configured for receiving an end of a strut shaft therethrough, wherein the lower plate is releasably adjustable with respect to the fastener plate along a first axis and a second axis, wherein the second axis is substantially non-parallel to the first axis;
- an upper plate having a downward face positioned adjacent to a top face of the lower plate wherein said threaded fastening members extend through the upper plate, wherein the upper plate and the lower plate are jointly configured for allowing the upper plate to be releasably adjustable with respect to the fastener plate along the second axis;
- wherein the lower plate comprises an upward face comprising a plurality of upwardly extending protruding members;
- wherein the upper plate comprises a plurality of elliptical apertures, an elliptical aperture of the plurality of elliptical apertures corresponding to and receiving one of each of said plurality of upwardly extending protruding members, wherein the receiving of one of each of said plurality of the upwardly extending protruding members with the corresponding elliptical apertures of the plurality of elliptical apertures allows relative movement between the upper plate and the lower plate along the first axis while inhibiting relative movement between the upper plate and the lower plate along the second axis.

An apparatus for adjusting caster and camber, the apparatus comprising:
- a fastener plate comprising a top face, the fastener plate comprising an interior cut-out portion defined by an interior peripheral wall of the fastener plate;
- a lower plate having a top side and a lower face thereof positioned adjacent the top face of the fastener plate, the lower plate comprising a plurality of elongated apertures, each elongated aperture adaptable for receiving a fastening member, the lower plate comprising a first side and a second side, the lower plate comprising a shaft housing depending from the lower face and extending through the interior cut-out portion of the fastener plate, the shaft housing having a bore configured for receiving an end of a strut shaft therethrough, wherein the lower plate is releasably adjustable with respect to the fastener plate along a first axis and a second axis, wherein the second axis is substantially perpendicular to the first axis and the plurality of elongated apertures are substantially parallel with the first axis;
- an upper plate having a forward side, a rearward side, a left side and a right side, the upper plate further comprising a lower face positioned adjacent to the top side of the lower plate such that the upper plate and the lower plate are jointly configured for allowing the upper plate to be moveable with respect to the fastener plate along the second axis;
- wherein the top side of the lower plate further comprises a pair of upwardly extending members;
- wherein the upper plate comprises a pair of elliptical apertures, an elliptical aperture corresponding to and receiving one of each upwardly extending members, wherein the engagement of each protruding member with the corresponding elliptical aperture allows relative movement between the upper plate and the lower plate along the first axis while inhibiting relative movement between the upper plate and the lower plate along the second axis;
- and
- a plurality of fasteners which extend between the fastener plate, the lower plate and the upper plate for attachment of the apparatus to a vehicle strut tower;
