Abstract
A ball joint assembly for control arm. The ball joint assembly has an upper portion with a ball socket and stud centered about a first centerline. A radial extension that is connected to the upper portion supports a mounting body with a second centerline and an outer diameter that fits within an aperture in the control arm. A threaded shaft depends from the mounting body and receives a nut to tighten against the control arm until the first centerline of the ball joint assembly is fixed in a desired position.
Claims1
A vehicle control arm assembly comprising:
- a control arm frame having an aperture with a first diameter;
- a ball joint assembly that is configured for assembly with the control arm frame in the aperture with the first diameter, the ball joint assembly having:
- a ball joint cup that is centered about a first centerline and has a radially extending portion with a mounting body that is centered on a second centerline;
- the mounting body has an outer diameter that complements the first diameter and a dependent threaded stud;
- a first lock washer with an inner diameter that is at least equal to the diameter of the mounting body;
- a second lock washer with an inner diameter that is at least equal to an outer diameter of the dependent threaded stud;
- and,
- an internally threaded closure that complements the threaded stud;
- whereby the ball joint assembly is fixed to the control arm frame at a desired position by tightening the first lock washer and the second lock washer against opposite surfaces of the control arm frame.
