Abstract
A suspension for a motor vehicle having a hollow suspension member including first and second spaced apart sidewalls and a pivot pin. In the preferred embodiment, the pivot pin is a locking assembly that includes a first retainer partially insertable through a first window formed in the first sidewall and a second retainer partially insertable through a second window formed in the second side wall. The first retainer engages the second retainer to present a pivot that receives a pivot arm between the sidewalls.

11-11. The suspension of claim 10 wherein one of the flanges is irregularly-shaped to correspond to a first irregularly-shaped window formed in the suspension link.
-
12-12. The suspension of claim 11 wherein the second retainer includes two radially extending and spaced apart flanges capturing a different portion of the suspension link therebetween.
-
13-13. The suspension of claim 12 wherein a fastener joins the first and second retainers.
-
14-14. The suspension of claim 2 wherein the pivot arm is formed from a single, contiguous material.
-
15-15. The suspension of claim 14, further including a split bearing positioned to support the pivot arm on the locking assembly.
-
16-16. The suspension of claim 1, wherein the pivot arm includes first and second end portions extending outwardly from the hollow portion, the first and second end portions being substantially centered between planes containing the first and second sidewalls.
-
17-17. The suspension of claim 16 wherein the first and second sidewalls are interconnected at one edge by a third wall and an opposite edge by a fourth wall.
-
18-18. The suspension of claim 17 wherein the first portion of the pivot arm extends through an aperture formed in the third wall and the second portion of the pivot arm extends through an aperture formed in the fourth wall.
-
19-19. The suspension of claim 1 wherein the pivot pin includes a first radially extending flange in engagement with one of the first and second sidewalls.
-
20-20. The suspension of claim 19 wherein the pivot pin includes a second radially extending flange spaced apart from the first flange, the second flange being in engagement with the other of the first and second shells.
-
21-21. The suspension of claim 20 wherein the pivot arm includes a first half secured to a second half, the first and second halves engaging one another along a plane that intersects the pivot pin.
-
22-22. The suspension of claim 21 further including a split bearing positioned between the first and second pivot arm halves and the pivot pin.
-
23-23. The suspension of claim 22 wherein the suspension further comprises a first link being coupled to a first end of the pivot arm, and a second link being coupled to a second end of the pivot arm.
-
24-24. The suspension of claim 23 wherein each of the first and second links includes a ball joint for coupling the first and second links to the pivot arm.
-
25. A method of making a suspension assembly having a tubular link with first and second spaced apart sidewalls, a pivot arm and a locking assembly having first and second retainers as well as a fastener, the method comprising:
-
positioning the pivot arm within a cavity formed in the tubular link; inserting a portion of the first retainer through a first window formed in the first sidewall; inserting a portion of the second retainer through a second window formed in the second sidewall; and interconnecting the first and second retainers with the fastener to present a pivot pin for rotatably supporting the pivot arm. - View Dependent Claims (26, 27)
