Abstract

A split bushing torque strut isolator assembly for a vehicle is provided. The assembly includes a lower bushing configured to be disposed in a vehicle structural component, a bushing housing configured to be coupled to the vehicle structural component, an upper bushing disposed at least partially within the bushing housing, the upper bushing being separate from the lower bushing, and a torque rod having a first end and a second end, the second end being disposed between the upper and lower bushings. A method of assembling the split bushing torque strut isolator assembly is also provided.

First claim

What is claimed is:

1. A split bushing torque strut isolator assembly for a vehicle, the assembly comprising:
a lower bushing disposed in a bushing receiving aperture formed in a vehicle structural component;
a bushing housing coupled to an upper surface of the vehicle structural component;
an upper bushing disposed at least partially within the bushing housing, the upper bushing being separate from the lower bushing, the bushing housing positioned over the lower bushing such that the upper bushing is positioned over the lower bushing and the upper bushing is not positioned in the bushing receiving aperture; and
a torque rod having a first end and a second end, the second end being disposed between the upper and lower bushings.

2. The assembly of claim 1 , wherein the vehicle structural component is a vehicle cradle and the torque rod first end is configured to be coupled to a vehicle engine; and
the bushing housing is coupled to the upper surface of the cradle and positioned over the bushing receiving aperture while remaining outside of the bushing receiving aperture.

3. The assembly of claim 1 , wherein the lower bushing comprises a first notched portion, and the upper bushing comprises a second notched portion.

4. The assembly of claim 3 , wherein the torque rod second end is disposed between the first and second notched portions and is at least partially supported by the upper and lower bushings.

5. The assembly of claim 1 , wherein the upper and lower bushings are elastomeric bushings.

6. The assembly of claim 1 , wherein the lower bushing comprises an inner diameter configured to receive a fastener.

7. The assembly of claim 6 , wherein the torque rod comprises an aperture configured to receive the fastener.

8. The assembly of claim 7 , wherein the upper bushing comprises an inner diameter configured to receive the fastener.

9. A method of assembling a split bushing torque strut isolator assembly, the method comprising:
providing a cradle having a bushing receiving aperture;
inserting a lower bushing into the bushing receiving aperture;
lowering a torque rod vertically onto the lower bushing without requiring horizontal movement of the torque rod;
providing a bushing housing having an upper bushing disposed at least partially in the bushing housing;
orienting the bushing housing over the torque rod such that the torque rod is disposed between the upper and lower bushings; and
coupling the bushing housing to an upper surface of the cradle.

10. The method of claim 9 , wherein orienting the bushing housing over the torque rod includes orienting the bushing housing over the torque rod such that the torque rod is disposed in notched portions of the upper and lower bushings and the upper bushing is not positioned in the cradle.

11. The method of claim 9 , further comprising disposing the upper bushing in the bushing housing.

12. The method of claim 9 , further comprising inserting a fastener through the lower bushing, the torque rod, and the upper bushing.

13. The method of claim 9 , further comprising coupling the torque rod to a vehicle engine before lowering the torque rod vertically onto the lower bushing such that the engine and torque rod coupled thereto are lowered vertically to position a second end of the torque rod onto the lower bushing without requiring any horizontal movement of the engine and torque rod.

14. The method of claim 9 , further comprising coupling the torque rod to a bracket coupled to a vehicle engine.
