Abstract

A seal assembly for an assembly of a vehicle is provided. The seal assembly comprises a seal configured to create a seal between first and second components of the vehicle assembly and a retaining element configured to couple the seal to the first component prior to assembly of the vehicle assembly, wherein at least a portion of the retaining element is deformable and is configured to deform from a first state to a second state during installation or use of the seal assembly, such that after said deformation the retaining element no longer couples the seal to the first component.

Claims

1. A seal assembly for an assembly of a vehicle, the seal assembly comprising:

a seal configured to create a seal between first and second components of the vehicle assembly; and

a retaining element configured to couple the seal to the first component prior to assembly of the vehicle assembly, wherein at least a portion of the retaining element is deformable and is configured to deform from a first state to a second state during installation or use of the seal assembly, such that after the deformation the retaining element no longer couples the seal to the first component.

2. The seal assembly of claim 1, wherein the retaining element or portion thereof is configured to deform from the first state to the second state due to the operating temperature of the seal assembly.

3. The seal assembly of claim 1, wherein the retaining element or portion thereof is frangible and is configured to break when the seal assembly is installed into the vehicle assembly.

4. The seal assembly of claim 1, wherein the retaining element is configured to be at least partially received within a bore formed in the first component.

5. The seal assembly of claim 1, wherein the retaining element is configured to extend through a bore defined in the first component.

6. The seal assembly of claim 1, wherein the seal defines a seal aperture configured to receive a fastener for coupling the first component to the second component, wherein the retaining element extends through the seal aperture.

7. The seal assembly of claim 6, wherein the retaining element defines a retainer aperture configured to receive a fastener.

8. The seal assembly of claim 7, wherein the retainer aperture is aligned with the seal aperture.

9. The seal assembly of claim 7, wherein the retaining element further comprises a grip member, wherein the grip member is configured to couple to the fastener received within the retainer aperture and provide resistance against the removal of the fastener from the retainer aperture.

10. The seal assembly of claim 9, wherein at least a portion of the grip member is configured to deform between a first state and a second state by virtue of the operating condition of the seal assembly such that the fastener is removed from the retainer aperture when the grip member or portion thereof is in the second state.

11. The seal assembly of claim 10, wherein the grip member or portion thereof is configured to deform under substantially the same conditions as the retaining element of portion thereof

12. The seal assembly of claim 1, wherein the retaining element is integral with the seal.

13. The seal assembly of claim 1, wherein the retaining element comprises a first flange, a second flange and a body portion extending between the first and second flanges.

14. The seal assembly of claim 13, wherein the body portion of the retaining element is configured to extend through a bore of the first component such that the first flange is arranged on a first side of the bore, and the second flange is arranged on a second side of the bore, and wherein the first flange and/or the body portion is flexible.

15. The seal assembly according to claim 13, wherein the first flange and/or the body portion comprise a plurality of slits configured to reduce the diameter of the first flange.

16. An assembly for a vehicle comprising:

a seal assembly with a seal, and a retaining element configured to couple the seal to a first component of the vehicle assembly prior to assembly of the vehicle assembly, wherein at least a portion of the retaining element is deformable and is configured to deform from a first state to a second state during installation or use of the seal assembly, such that after the deformation the retaining element no longer couples the seal to the first component; and

wherein the retaining element comprises a first flange, a second flange and a body portion extending between the first and second flanges.

17. The assembly of claim 16, wherein the first component comprises a counter-bore, and wherein the first flange of the retaining element is at least partially received within the counter-bore, and wherein the seal is arranged between the second flange of the retaining element and the first component.

18. The assembly of claim 16, wherein the vehicle assembly further comprises a second component, and a fastener configured to couple the first component to the second component of the vehicle assembly;

wherein a head of the fastener has a larger diameter than the first flange of the retaining element; and

wherein the fastener comprises a shank having a mid portion and a distal portion, the mid portion having a smaller diameter than the distal portion, and the mid portion and the distal portion being separated by a shoulder, wherein the retaining member acts against the shoulder in order to provide resistance against removal of the fastener.

19. The assembly of claim 16, wherein the first component comprises a drain channel configured to allow a melted portion of the retaining element to drain away from the seal;

wherein the first component comprises a chamber, the chamber being configured such that the melted portion of the retaining element is received within the chamber;

wherein the first component comprises a bore configured to receive a fastener to couple the first component to the second component of the vehicle assembly, and wherein the retaining element is at least partially received within the bore.

20. The assembly of claim 16, wherein the second component comprises a bore configured to receive a fastener to couple the first component to the second component;

wherein the second component comprises a counter-bore configured to receive a portion of the retaining element; and

wherein the second component comprises a drain channel configured to allow the melted portion of the retaining element to drain away from the seal.
