Abstract

An improved bracket assembly for receiving a brake assembly and a brake actuator is provided. The bracket assembly includes a tube configured to receive a camshaft of the brake assembly and an actuator mounting bracket disposed proximate a first end of the tube. The actuator mounting bracket is configured for coupling to the actuator and defines an aperture configured to receive the tube. The bracket assembly further includes a brake spider mounting bracket disposed proximate a second end of the tube. The spider mounting bracket includes a body defining inboard and outboard sides, is configured to receive a brake spider on the outboard side and defines an aperture configured to allow the tube to extend therethrough. The spider mounting bracket further includes a neck extending from the inboard side of the body that is configured to receive the tube and positions the weld away from the body to reduce stress.

First claim

1 . A bracket assembly for receiving a brake assembly and a brake actuator, comprising:
a tube configured to receive a camshaft of the brake assembly; an actuator mounting bracket disposed proximate a first end of said tube, said actuator mounting bracket configured for coupling to said actuator and defining an aperture configured to receive said tube; and, a brake spider mounting bracket disposed proximate a second end of said tube, said brake spider mounting bracket including:
a body defining inboard and outboard sides, said body configured to receive a brake spider on said outboard side and defining an aperture configured to allow said tube to extend therethrough; and,
a neck extending from said inboard side of said body, said neck configured to receive said tube
wherein said brake spider mounting bracket is joined to said tube with a weld at an inboard end of said neck distant from said body.

2 . The bracket assembly of claim 1 wherein said body and said neck form a unitary structure.

3 . (canceled)

4 . The bracket assembly of claim 1 wherein an outer diameter of said neck varies along a length of said neck.

5 . The bracket assembly of claim 1 , further comprising a first rib extending from said inboard side of said body to a first point on said neck distant from said body.

6 . The bracket assembly of claim 5 wherein a depth of said first rib continually increases moving from said body to said first point on said neck.

7 . The bracket assembly of claim 5 wherein said brake spider mounting bracket further comprises a second rib extending from said inboard side of said body to a second point on said neck distant from said body.

8 . The bracket assembly of claim 7 wherein said first and second ribs are circumferentially spaced less than one hundred and eighty degrees from one another about said neck.

9 . The bracket assembly of claim 7 wherein said first and second ribs are not identical in shape.

10 . The bracket assembly of claim 1 wherein said brake spider mounting bracket is joined to said tube with a weld at an outboard end of said neck.

11 . A brake and bracket assembly, comprising:
a brake assembly, comprising:
a brake spider;
first and second brake shoes having first ends coupled to said brake spider; and,
a camshaft extending through said brake spider and having a cam at a first end configured to engage second ends of said first and second brake shoes, rotation of said cam causing said first and second brake shoes to move between positions of engagement and disengagement with a braking surface; and,
a bracket assembly for receiving said brake assembly and a brake actuator, comprising:
a tube configured to receive said camshaft;
an actuator mounting bracket disposed proximate a first end of said tube, said actuator mounting bracket configured for coupling to said actuator and defining an aperture configured to receive said tube; and,
a brake spider mounting bracket disposed proximate a second end of said tube, said brake spider mounting bracket including:
a body defining inboard and outboard sides, said body configured to receive said brake spider on said outboard side and defining an aperture configured to allow said tube to extend therethrough; and,
a neck extending from said inboard side of said body, said neck configured to receive said tube

wherein said brake spider mounting bracket is joined to said tube with a weld at an inboard end of said neck distant from said body.

12 . The brake and bracket assembly of claim 11 wherein said body and said neck form a unitary structure.

13 . (canceled)

14 . The brake and bracket assembly of claim 11 wherein an outer diameter of said neck varies along a length of said neck.

15 . The brake and bracket assembly of claim 11 , further comprising a first rib extending from said inboard side of said body to a first point on said neck distant from said body.

16 . The brake and bracket assembly of claim 15 wherein a depth of said first rib continually increases moving from said body to said first point on said neck.

17 . The brake and bracket assembly of claim 15 wherein said brake spider mounting bracket further comprises a second rib extending from said inboard side of said body to a second point on said neck distant from said body.

18 . The brake and bracket assembly of claim 17 wherein said first and second ribs are circumferentially spaced less than one hundred and eighty degrees from one another about said neck.

19 . The brake and bracket assembly of claim 17 wherein said first and second ribs are not identical in shape.

20 . The brake and bracket assembly of claim 11 wherein said brake spider mounting bracket is joined to said tube with a weld at an outboard end of said neck.

21 . The bracket assembly of claim 1 wherein said neck encircles said tube.
