Abstract
A control arm for vehicle suspensions includes an arm structure having first and second elongated portions that extend from a central portion to form a U or V shaped structure. The arm structure includes a spindle mount at the central position for mounting a spindle. A cross member extends between the first and second elongated portions, and one or more self-aligning ball bearings pivotably interconnect the arm structure to the cross member.
Claims18
A control arm assembly for a motor vehicle suspension, comprising:
- a substantially rigid arm structure having a central portion configured to attach to a spindle, and front and rear portions extending from the central portions and defining first and second end portions, respectively;
- a cross member configured to be mounted to a vehicle frame structure, the cross member extending between the first and second end portions;
- first and second angularly misaligning ball bearings pivotably interconnecting the front and rear portions, respectively, of the rigid arm structure to the cross member at spaced-apart locations and defining a pivot axis about which the arm structure pivots relative to the cross member;
- and wherein:
- the first and second angularly misaligning ball bearings each include an outer race, an inner race, and a plurality of rolling bearing elements movably engaging the inner and outer races, and wherein the inner race rotates about a first axis and the outer race rotates about a second axis, and wherein the inner and outer races rotate freely relative to one another even if the first and second axes are significantly misaligned.
2 more elements
