Abstract

An mounting bracket 50 which attaches an alternator 18 to a vehicle engine 14 and which substantially reduces the amount of noise which is produced by the alternator 18 as the engine is idling.

Claims

1. An alternator mounting bracket having a relatively wide and generally planar body portion and a generally thin protruding portion which is selectively attached to the alternator.

2. The alternator mounting bracket of claim 1 wherein said body portion has a first width and wherein said protruding portion has a second width which is about one tenth of said first width.

3. The alternator mounting bracket of claim 2 wherein said protruding portion orthogonally projects from said body portion.

4. The alternator mounting bracket of claim 3 wherein said protruding portion includes a generally round attachment portion having an aperture which selectively receives a fastening member.

5. The alternator mounting bracket of claim 4 wherein said alternator includes a mounting flange and wherein said protruding portion is selectively disposed upon said mounting flange and wherein said fastening member selectively attaches said protruding portion to said flange.

6. A mounting bracket for use with an alternator of the type which is selectively deployed upon an engine which selectively occupies an idle state, the alternator producing a certain amount of noise when said engine selectively occupies said idle state, said mounting bracket comprising a first portion which is selectively attached to said engine;

and a second portion which is selectively attached to said alternator, thereby allowing said alternator to be attached to said engine without increasing said certain amount of noise.

7. The mounting bracket of claim 6 wherein said first portion is generally flat and relatively thick.

8. The mounting bracket of claim 7 wherein said second portion is relatively thin.

9. The mounting bracket of claim 8 wherein said first portion has a first width and wherein said second portion has a second width which is about one tenth of said first width.

10. The mounting bracket of claim 9 wherein said first portion has a first longitudinal axis of symmetry and wherein said second portion has a second longitudinal axis of symmetry.

11. The mounting bracket of claim 10 wherein said second longitudinal axis of symmetry is substantially orthogonal to said first longitudinal axis of symmetry.

12. The mounting bracket of claim 11 wherein said second portion includes a generally round portion which includes an aperture which selectively receives a fastening member.

13. The mounting bracket of claim 12 wherein said fastening member comprises a bolt.

14. The mounting bracket of claim 6 wherein said noise is reduced to a level which is substantially imperceptible to a vehicle occupant'"'"'s ear.

15. The mounting bracket of claim 6 wherein said noise is reduced to a level substantially identical to that produced by the alternator without the use of said bracket.

16. A method for reducing the noise produced by an alternator of the type which is selectively mounted to an engine by a bracket, said method comprising the step of:

selectively thinning a certain portion of the bracket.

17. The method of claim 16 wherein said bracket has a first portion which is selectively coupled to the engine and a second portion which is coupled to the alternator and wherein said second portion comprises said certain portion.

18. The method of claim 17 wherein said first portion has a first width and wherein said second portion has a second width, said method further comprising the step of causing said second width to be about one tenth of said first width.

19. The method of claim 18 further comprising the step of causing said second portion to orthogonally project from said first portion.

20. The method of claim 19 further comprising causing said first and second portions to have respective and longitudinal axes of symmetry and causing said longitudinal axis of symmetry of said first portion to be orthogonal to said longitudinal axis of symmetry of said second portion.
