Abstract

A vehicle suspension arrangement includes a mounting bracket, a trailing arm, an air spring assembly configured to bias a second end of the trailing arm from a vehicle frame member, an axle assembly couple to the trailing arm, and a trailing arm connection assembly that includes a connector having a first portion received within an aperture of the mounting bracket, and a second portion extending outwardly from the first portion and including an aperture, a bushing member received within a first end of the trailing arm, a pin member received within the bushing member and including a first aperture, and a first mechanical fastener received within the first aperture of the pin member and within the aperture of the second portion of the first connector, thereby pivotably securing the trailing arm to the mounting bracket.

First claim

The invention claimed is:

1. A vehicle suspension arrangement, comprising:
a mounting bracket configured to be secured to a vehicle frame member;
a trailing arm having a first end and a second end;
an air spring assembly configured to bias the second end of the trailing arm from the vehicle frame member;
an axle assembly coupled to the trailing arm along a length thereof; and
a trailing arm connection assembly pivotably coupling the first end of the of the trailing arm to the mounting bracket, the trailing arm connection assembly comprising:
a first connector having a first portion received within a first aperture of the mounting bracket, and a second portion extending outwardly from the first portion and including an aperture;
a bushing member received within the first end of the trailing arm;
a pin member received within the bushing member and including a first aperture; and
a first mechanical fastener received within the first aperture of the pin member and within the aperture of the second portion of the first connector, thereby pivotably securing the trailing arm to the mounting bracket

wherein the first connector engages the mounting bracket such that the first connector is prevented from rotating with respect to the mounting bracket.

2. The vehicle suspension arrangement of claim 1 , wherein at least one of the aperture of the second portion of the first connector and the aperture of the pin member is threaded.

3. The vehicle suspension arrangement of claim 1 , wherein the mechanical fastener includes a bolt.

4. The vehicle suspension arrangement of claim 1 , wherein the first portion of the connector is cylindrically-shaped.

5. The vehicle suspension arrangement of claim 4 , wherein the first connector includes a first engagement portion and the mounting bracket includes a second engagement portion that prevents misalignment of the first connector with respect to the mounting bracket during assembly.

6. The vehicle suspension arrangement of claim 5 , wherein the first engagement portion includes a tab and the second engagement portion includes a relief.

7. The vehicle suspension arrangement of claim 1 , wherein the first connector is welded to the mounting bracket.

8. The vehicle suspension arrangement of claim 1 , wherein the trailing arm connection assembly further comprises a second connector having a first portion received within a second aperture of the mounting bracket, and a second portion extending outwardly from the first portion of the second connector and including an second aperture, the pin member including a second aperture, and a second mechanical fastener received within the second aperture of the pin member and within the aperture of the second portion of the second connector.

9. The vehicle suspension arrangement of claim 8 , wherein the second portion of the first connector extends only partially about a circumference of the first connector, the second portion of the second connector extends only partially about a circumference of the second connector, and wherein the second portion of the first connector is rotationally offset from the second portion of the second connector about a longitudinal axis of the pin member.

10. The vehicle suspension arrangement of claim 1 , wherein the pin member includes a circular cross-sectional configuration.

11. A vehicle suspension arrangement, comprising:
a mounting bracket configured to be secured to a vehicle frame member;
a trailing arm having a first end and a second end;
an air spring assembly configured to bias the second end of the trailing arm from the vehicle frame member;
an axle assembly coupled to the trailing arm along a length thereof; and
a trailing arm connection assembly pivotably coupling the first end of the of the trailing arm to the mounting bracket, the first trailing arm connection assembly comprising:
a first connector having a cylindrically-shaped first portion received within a first aperture of the mounting bracket, and a second portion extending outwardly from the first portion and including an aperture;
a second connector having a cylindrically-shaped first portion received within a second aperture of the mounting bracket, and a second portion extending outwardly from the first portion of the second connector and including an aperture;
a bushing member received within the first end of the trailing arm;
a pin member received within the bushing member and including a first aperture located proximate a first end of the pin member and a second aperture located proximate a second end of the pin member;
a first mechanical fastener received within the first aperture of the pin member and within the aperture of the second portion of the first connector, and a second mechanical fastener received within the second aperture of the pin member and within the aperture of the second portion of the second connector, thereby pivotably securing the trailing arm to the mounting bracket; and

wherein the first and second connectors each engage the mounting bracket such that both the first and the second connectors are prevented from rotating with respect to the mounting bracket.

12. The vehicle suspension arrangement of claim 11 , wherein at least one of the aperture of the second portion of the first connector and the first aperture of the pin member is threaded.

13. The vehicle suspension arrangement of claim 11 , wherein the first mechanical fastener includes a bolt.

14. The vehicle suspension arrangement of claim 11 , wherein the first connector includes a first engagement portion and the mounting bracket includes a second engagement portion the prevents misalignment of the first connector with respect to the mounting bracket during assembly.

15. The vehicle suspension arrangement of claim 14 , wherein the first engagement portion includes a tab and the second engagement portion includes a relief.

16. The vehicle suspension arrangement of claim 11 , wherein the first connector is welded to the mounting bracket.

17. The vehicle suspension arrangement of claim 16 , wherein the second portion of the first connector extends only partially about a circumference of the first connector, the second portion of the second connector extends only partially about a circumference of the second connector, and wherein the second portion of the first connector is rotationally offset from the second portion of the second connector about a longitudinal axis of the pin member.

18. The vehicle suspension arrangement of claim 11 , wherein the pin member includes a circular cross-sectional configuration.

19. A connector assembly, comprising:
a connector member configured to pivotably couple a vehicle suspension component to a mounting structure of a vehicle suspension arrangement, comprising:
a cylindrically-shaped first portion configured to be received within an aperture of a mounting structure, the first portion including a longitudinally extending bore;
an arm portion extending in an axial direction from the first portion and including an aperture configured to receive a mechanical fastener therein; and
at least one tab member extending radially outward from the first portion, wherein the at least one tab member is configured to be received within a notch of the aperture of the mounting structure thereby preventing misalignment of the connector member with the mounting structure;
a pin member received within the bore of the first portion of the connector member and includes an aperture; and
a first mechanical fastener received within the aperture of the
