Abstract

The invention concerns an engine-mounted fan shroud for use in a vehicle that has a shroud body supported by a vehicle engine, including an outer ring made of a first material having a first stiffness, and a bodyside seal extending from and being integral with the outer ring, with the bodyside seal being made of a second material having a second stiffness that is less than the first stiffness. The bodyside seal fits into and seals around a seal opening in a body-mounted shroud that is mounted to radiator support structure.

Claims (24)

1. An engine mounted fan shroud for use in a vehicle comprising:

a shroud body, adapted to be supported by a vehicle engine, including an outer ring made of a first material having a first stiffness; and

a bodyside seal extending from and being integral with the outer ring, with the bodyside seal being made of a second material having a second stiffness that is less than the first stiffness.

2. The engine mounted fan shroud of claim 1 wherein the bodyside seal is made of a thermoplastic elastomer.

3. The engine mounted fan shroud of claim 2 wherein the shroud body is made of nylon.

4. The engine mounted fan shroud of claim 1 wherein the shroud body includes a plurality of generally radially extending stators adapted to redirect air flowing thereacross.

5. The engine mounted fan shroud of claim 4 wherein the shroud body includes a central ring affixed to radially inner ends of each of the stators.

6. The engine mounted fan shroud of claim 1 wherein the shroud body further includes a plurality of mounting bosses extending therefrom.

7. The engine mounted fan shroud of claim 6 wherein each of the mounting bosses includes a grommet insert molded therein.

8. The engine mounted fan shroud of claim 1 wherein the outer ring includes a lip to which the integral bodyside seal is fused.

9. An engine fan shroud assembly for use in a vehicle comprising:

a body mounted shroud, adapted to be mounted to a support structure of a vehicle body, including a generally cylindrical seal opening; and

an engine mounted fan shroud, adapted to be supported by a vehicle engine, having a shroud body including an outer ring made of a first material and having a first stiffness, and a bodyside seal extending from and being integral with the outer ring and being in sealing surface contact with the seal opening, and with the bodyside seal being made of a second material having a second stiffness that is less than the first stiffness.

10. The engine fan shroud assembly of claim 9 wherein the bodyside seal is made of a thermoplastic elastomer.

11. The engine fan shroud assembly of claim 10 wherein the shroud body is made of nylon.

12. The engine fan shroud assembly of claim 9 wherein the shroud body includes a plurality of generally radially extending stators adapted to redirect air flowing thereacross.

13. The engine fan shroud assembly of claim 12 wherein the shroud body includes a central ring affixed to radially inner ends of each of the stators.

14. The engine fan shroud assembly of claim 9 wherein the outer ring includes a lip to which the integral bodyside seal is fused.

15. The engine fan shroud assembly of claim 9 wherein the shroud body includes a plurality of mounting bosses extending therefrom, and the engine fan shroud assembly includes a plurality of brackets each secured to one of the mounting bosses and adapted to mount to the vehicle engine.

16. The engine fan shroud assembly of claim 9 wherein the body mounted shroud has an upper shroud portion and a lower shroud portion mounted to the upper shroud portion.

17. An engine mounted fan shroud for use in a vehicle comprising:

a shroud body, adapted to be supported by a vehicle engine, including an outer ring, a central ring, and a plurality of generally radially oriented stators extending between the outer ring and the central ring and adapted to redirect air flowing thereacross, with the outer ring including a lip extending therefrom, and wherein the shroud body is made of a first material having a first stiffness; and

a bodyside seal extending from and being integral with the lip, with the bodyside seal being made of a second material having a second stiffness that is less than the first stiffness.

18. The engine mounted fan shroud of claim 17 wherein the bodyside seal is made of a thermoplastic elastomer.
