Claims27
A brake beam assembly comprising:
- a generally V-shaped tension member having a first end portion and a second end portion opposite the first end portion and an apex portion located between the first end portion and the second end portion, the first end portion of the generally V-shaped tension member having a first aperture and a second aperture, and the second end portion of the generally V-shaped tension member having a first aperture and a second aperture;
- a compression member having a first end portion and a second end portion opposite the first end and a central portion positioned between the first end portion and the second end portion, the first end portion of the compression member having a first aperture and a second aperture, and the second end portion of the compression member having a first aperture and a second aperture;
- a strut member positioned between the generally V-shaped tension member and the compression member, the strut member having a first end portion and a second end portion opposite the first end portion, the first end portion of the strut member attached to the apex portion of the generally V-shaped tension member, the second end portion of the strut member attached to the central portion of the compression member;
- a first end extension having a pocket guide coupling portion and a brake head coupling portion, the brake head coupling portion having a first opening and a second opening, the pocket guide coupling portion sized and configured for attachment to a portion of a railway car;
- a second end extension having a pocket guide coupling portion and a brake head coupling portion, the brake head coupling portion having a first opening and a second opening, the pocket guide coupling portion sized and configured for attachment to a portion of a railway car;
- a first brake head having a cavity sized and configured to receive the first end portion of the tension member, the first end portion of the compression member and the brake head coupling portion of the first end extension, the cavity being in communication with a first hole and a second hole formed in the first brake head, the first end portion of the compression member, the first end portion of the tension member and the brake head coupling portion of the first end extension positioned within the cavity of the first brake head such that the first aperture of the first end portion of the tension member, the first aperture of the first end portion of the compression member, the first opening of the brake head coupling portion of the first end extension and the first and second holes of the first brake head are aligned to receive a first fastener attaching the first end portion of the compression member, the first end portion of the tension member and the brake head coupling portion of the first end extension to the first brake head;
- and
- a second brake head having a cavity sized and configured to receive the second end portion of the tension member, the second end portion of the compression member and the brake head coupling portion of the second end extension, the cavity being in communication with a first hole and a second hole formed in the second brake head, the second end portion of the compression member, the second end portion of the tension member and the brake head coupling portion of the second end extension positioned within the cavity of the second brake head such that the first aperture of the second end portion of the tension member, the first aperture of the second end portion of the compression member, the first opening of the brake head coupling portion of the second end extension and the first and second holes of the second brake head are aligned to receive a second fastener attaching the second end portion of the compression member, the second end portion of the tension member and the brake head coupling portion of the second end extension to the second brake head,
- wherein the first end extension, the first end portion of the tension member and the first end portion of the compression member are aligned such that the second opening of the brake head coupling portion of the first end extension, the second aperture of the first end portion of the tension member and the second aperture of the first end portion of the compression member are aligned to receive a third fastener attaching the first end extension, the first end portion of the tension member and the first end portion of the compression member together at a position external to the first brake head cavity and positioned closer to the central portion of the compression member than the first brake head,
- wherein the second end extension, the second end portion of the tension member and the second end portion of the compression member are aligned such that the second opening of the brake head coupling portion of the second end extension, the second aperture of the second end portion of the tension member and the second aperture of the second end portion of the compression member are aligned to receive a fourth fastener attaching the second end extension, the second end portion of the tension member and the second end portion of the compression member together at a position external to the second brake head cavity and positioned closer to the central portion of the compression member than the second brake head,
- wherein the first end extension and first brake head are independent structures, and
- wherein the second end extension and the second brake head are independent structures.

A brake beam assembly comprising:
- a compression member having first and second end portions;
- a tension member having first and second end portions;
- a strut member attached between the tension member and the compression member;
- a first end extension having first and second portions;
- a first brake head having a generally U-shaped retaining member;
- and
- first and second fasteners,
- wherein the generally U-shaped retaining member of the first brake head receives the first end portion of the tension member, the first end portion of the compression member and the first portion of the first end extension such that the first fastener extends through apertures formed in the generally U-shaped retaining member, compression member, tension member and first end extension to attach the first brake head, tension member, compression member and first end extension together,
- wherein the second portion of the first end extension extends beyond the generally U-shaped retaining member and is positioned external to the generally U-shaped retaining member of the first brake head such that the second portion of the first end extension is closer to the strut than the generally U-shaped retaining member of the first brake head, and
