Off-axis cam adjustment system and method
View Patent ↗A system and method for adjusting at least one of a camber and a caster of a suspension system. The system includes a lower control arm and a suspension member coupled to the lower control arm. The system also includes a plate or plates defining a slot, the slot having a cam retaining element. In addition, the system includes one or more cams retained by the cam retaining element, the cam or cams defining an off-axis opening. The system also includes a bolt extending through the slot and through the off-axis opening in the cam. Upon rotation of the cam, the at least one plate is caused to move relative to the suspension member, which in turn causes the suspension member to move relative to the lower control arm.
1. A system for adjusting at least one of a camber and a caster of a suspension system, comprising:
a control arm;
at least one plate including an opening, a slot, and a cam retaining element;
a suspension member coupled to the control arm;
at least one cam retained by the cam retaining element and including an off-axis opening; and
a bolt extending through the slot and through the off-axis opening, and
a second bolt extending through at least one opening in the control arm, at least one slot in the suspension member, and the opening in the at least one plate,
wherein a rotation of the cam causes the plate to move relative to the suspension member to cause relative movement between the suspension member and the control arm.
2. The system of claim 1 , wherein the plate includes a pair of plates, each plate including an opening, a slot, and cam retaining elements, the at least one cam including a pair of cams retained by the cam retaining elements, each cam including an off-axis opening, a rotation of the cam causes the plates to move relative to the suspension member to cause the suspension member to move relative to the control arm.
3. The system of claim 2 , wherein each cam retaining element includes a pair of elements that are elevated relative to a surface of the plates.
4. The system of claim 3 , wherein the elevated element are disposed at a distance from each other that is slightly less than or equal to an outer diameter of the cams.
5. The system of claim 1 , wherein the cam is round.
6. The system of claim 1 , wherein the the plate has a threaded connector, the second bolt receivable in the threaded connector to fixedly couple the plate to the control arm.
7. The system of claim 1 , further comprising a second suspension member coupled to the control arm.
8. The system of claim 7 , wherein the system is configured such that the relative movement of the control arm with respect to both the suspension member and the second suspension member causes an adjustment to the camber of the suspension system.
9. The system of claim 7 , wherein the system is configured such that the relative movement of the control arm with respect to one of the suspension member and the second suspension member causes an adjustment to the caster of the suspension system.
10. A method for adjusting at least one of camber and a caster of a suspension system, the suspension system including a control arm having at least one opening, a suspension member coupled to the control arm, at least one plate including an opening, a slot and a cam retaining element, at least one cam retained by the cam retaining element and including an off-axis opening, a bolt extending through the slot and through the off-axis opening in the cam, and second bolt extending through the at least one opening in the control arm and the opening in the plate, comprising the steps of:
loosening the bolt and the second bolt;
rotating the cam so as to cause the plate to move relative to the suspension member to cause relative movement between the suspension member and the control arm.
11. The method of claim 10 , wherein the plate includes a threaded connection, the second bolt receivable in the threaded connection, the method further comprising the step of engaging the second bolt with the threaded connection such that the plate is fixedly coupled to the control arm.
12. The method of claim 10 , further comprising the step of coupling a second suspension member to the control arm.
13. The method of claim 12 , further comprising the step of adjusting the camber of the suspension system by causing relative movement of the control arm with respect to both the suspension member and the second suspension member.
14. The method of claim 12 , further comprising the step of adjusting the caster of the suspension system by causing relative movement of the control arm with respect to one of the suspension member and the second suspension member.
