Abstract

A brake assembly adapted to be mounted to the flange of an axle housing. The brake assembly includes a stationary plate having a plurality of threaded holes therein. The brake assembly also includes a mounting sleeve positioned adjacent to the axle housing flange opposite the stationary plate. A plurality of holes are provided through the mounting sleeve and are aligned with the threaded holes in the stationary plate. A bolt is received through each of the holes in the mounting sleeve and the aligned holes in the axle housing flange and the threaded holes in the stationary plate to secure the brake to the axle housing. The mounting sleeve may be provided in two or more separate pieces in order to facilitate installation.

Claims

1. A brake assembly adapted to be mounted to an axle housing flange including a plurality of holes therethrough, the brake comprising a stationary plate, a plurality of threaded holes in said stationary plate, a mounting sleeve positioned adjacent the axle housing flange on a side opposite said stationary plate, a plurality of holes through said mounting sleeve, and a plurality of bolts, said bolts having a threaded portion and a head, said bolts being received in said holes in said mounting sleeve, said holes through the axle housing flange, and said threaded holes in said stationary plate to secure the brake to the axle housing.

2. The brake of claim 1, wherein said threaded channels extend only partially through said stationary plate.

3. The brake of claim 1, wherein said mounting sleeve is generally annular in shape and includes an interior diameter approximately equal to but slightly larger than an exterior diameter of the axle housing adjacent the axle housing flange.

4. The brake of claim 1, wherein said mounting sleeve is formed from two or more pieces to facilitate installation.

5. The brake of claim 4, wherein each of said pieces includes at least two holes therethrough, and wherein a bolt is received in each of said holes in said pieces to secure said pieces of said mounting sleeve to said axle housing flange and said stationary plate.

6. The brake of claim 1, further comprising a cover plate that engages said stationary plate to form an inner chamber, and a seal positioned between said cover plate and said stationary plate to form a fluid-tight seal.

7. The brake of claim 6, further comprising a cooling and lubricating fluid within said inner chamber.

8. The brake of claim 7, further comprising a disc stack including alternating rotating discs and stationary discs, said rotating discs being rotationally coupled to a hub.

9. A wheel hub assembly comprising an axle, an axle housing having a flange, and a brake assembly secured to said axle housing flange, said brake assembly including a stationary plate, a plurality of threaded channels in said stationary plate, a mounting sleeve positioned adjacent said axle housing flange on a side opposite said stationary plate, a plurality of holes through said mounting sleeve, and a plurality of bolts, said bolts having a threaded portion and a head, said bolts being received in said holes in said mounting sleeve, said holes through the axle housing flange, and said threaded channels to secure the brake to the axle housing.

10. The wheel hub assembly of claim 9, wherein said threaded channels extend only partially through said stationary plate.

11. The wheel hub assembly of claim 9, wherein said mounting sleeve is generally annular in shape and includes an interior diameter approximately equal to but slightly larger than an exterior diameter of the axle housing adjacent the axle housing flange.

12. The wheel hub assembly of claim 9, wherein said mounting sleeve includes at least two separate arcuate pieces that together form a generally annular mounting sleeve.

13. The wheel hub assembly of claim 12, where each of said arcuate pieces include at least two holes therethrough, and wherein a bolt is received in each of said holes in said arcuate pieces to secure said arcuate pieces of said mounting sleeve to said axle housing flange and said stationary plate.

14. The wheel hub assembly of claim 9, further comprising a cover plate that engages said stationary plate to form an inner chamber, and a seal positioned between said cover plate and said stationary plate to form a fluid-tight seal.

15. The wheel hub assembly of claim 14, further comprising a cooling and lubricating fluid within said inner chamber.

16. The wheel hub assembly of claim 15, further comprising a disc stack including alternating rotating discs and stationary discs, said rotating discs being rotationally coupled to a hub.

17. A brake assembly adapted to be mounted to a flange of an axle housing, the brake assembly comprising a brake housing including a stationary plate, a plurality of threaded holes extending partially through said stationary plate, a generally annular mounting sleeve adapted to be positioned around the axle housing on a side of the flange opposite said stationary plate, the mounting sleeve including more than one pieces, a plurality of holes through said mounting sleeve aligned with said threaded holes in said stationary plate, and a plurality of bolts having a threaded end, the bolts being received in said holes in said mounting sleeve and said threaded holes in said stationary plate to secure said brake housing to said axle housing.
