Spare tire carrier vibration damper
View Patent ↗An apparatus for damping vibration in a vehicle structure via a mass of a spare wheel includes a bar. The bar has a first end elastically coupled to the vehicle structure, wherein the first end is arranged for vertical movement relative to the vehicle structure. The bar also has a second end pivotably coupled to the vehicle structure, wherein the second end is arranged to facilitate the vertical movement of the first end. The bar additionally includes an arrangement for mounting a spare wheel, wherein damping of vibration in the vehicle structure is provided when the spare wheel is mounted on the bar.
1. An apparatus for damping vibration in a vehicle structure via a mass of a spare wheel, comprising
a bar having
i) a first end fixedly coupled to a first cross-member, the first cross-member elastically coupled to the vehicle structure and arranged for vertical movement relative to the vehicle structure;
ii) a second end pivotably coupled to the vehicle structure and arranged to facilitate the vertical movement of the first end; and
an arrangement on the bar for mounting a spare wheel;
wherein damping of vibration in the vehicle structure is provided when the spare wheel is mounted on the bar,
wherein the vehicle structure comprises a second cross-member to which the second end is pivotably coupled for relative motion between the second cross-member and the second end.
2. An apparatus of claim 1 wherein the vehicle structure comprises a frame, and the first cross-member is elastically coupled to the frame.
3. An apparatus of claim 1 wherein the arrangement for mounting the spare wheel is positioned between the first end and the second end to optimize damping.
4. An apparatus of claim 1 wherein the coupling of the second end is via a hinge.
5. An apparatus of claim 1 wherein the arrangement for mounting the spare wheel comprises a bolt and a wing-nut arrangement.
6. An apparatus of claim 1 wherein the vehicle structure comprises a frame and the bar is arranged on an underside of the frame.
7. A vehicle having an apparatus for damping vibration in the vehicle using a spare wheel, the vehicle comprising
a frame;
a first cross-member mounted on the frame;
a second cross-member elastically mounted on the frame relative to the first cross-member and arranged for vertical movement relative to the vehicle structure;
a spare wheel; and
a bar arranged for mounting the spare wheel, the bar having a first end and a second end, the first end pivotably coupled to the first cross-member and the second end coupled to the second cross-member, the first end being arranged to facilitate the vertical movement of the second cross-member;
wherein damping of vibration in the vehicle structure is provided when the spare wheel is mounted on the bar.
8. An apparatus of claim 7 wherein an arrangement for mounting the spare wheel to the bar is positioned between the first end and the second end to optimize damping.
9. An apparatus of claim 7 wherein the coupling of the first end is via a hinge.
10. An apparatus of claim 8 wherein the arrangement for mounting the spare wheel to the bar comprises a bolt and a wing-nut arrangement.
11. An apparatus of claim 7 wherein the bar is arranged on an underside of the frame.
12. An apparatus for damping vibration in a vehicle structure via a mass of a spare wheel, comprising
a bar having
i) a first end fixedly coupled to a first cross-member, the first cross-member elastically coupled to the vehicle structure and arranged for vertical movement relative to the vehicle structure;
ii) a second end pivotably coupled to the vehicle structure and arranged to facilitate the vertical movement of the first end; and
an arrangement on the bar for mounting a spare wheel;
wherein damping of vibration in the vehicle structure is provided when the spare wheel is mounted on the bar,
wherein the vehicle structure comprises a first cross-member to which the second end is pivotably coupled.
13. An apparatus of claim 12 wherein the vehicle structure comprises a frame, wherein the first cross-member is elastically coupled to the frame, and wherein the second cross-member is fixedly coupled to the frame.
14. An apparatus of claim 12 wherein the arrangement for mounting the spare wheel is positioned between the first end and the second end to optimize damping.
15. An apparatus of claim 12 wherein the coupling of the second end is via a hinge.
16. An apparatus of claim 12 wherein the arrangement for mounting the spare wheel comprises a bolt and a wing-nut arrangement.
17. An apparatus of claim 12 wherein the vehicle structure comprises a frame and the bar is arranged on an underside of the frame.
