Abstract: A low weight and low cost brake beam assembly having high static strength and fatigue resistance having two independent brake heads each including a receiving section for receiving and retaining an end of a tension member, an end of a compression member and a portion of an end extension.

Abstract: A lubricating arrangement for an end guide of a railcar truck mounted brake rigging includes at least one elongated groove provided in the at least one surface of the end guide in open communication therewith, the elongated groove having a length thereof disposed generally transverse to a direction of the sliding reciprocal movement of the end guide. A lubricating member is secured within the at least one elongated groove, the lubricating member has a thickness portion thereof protruding, a predetermined height at initial installation, above the at least one surface of the end guide. The predetermined height of the protruding thickness portion is reduced during the reciprocal movement of the end guide within the channel or pocket so that material removed from the predetermined height during the reciprocal movement substantially resurfaces the at least one surface of the end guide.

Abstract: An improved unit guide wear plate for brake beams, which provides a brake beam centering force and aligns the movement of a brake beam end guide within the side frame of a railroad car truck so that the brake shoes can provide the maximum amount of force against the wheels when stopping the railroad car, and which is less prone to fracture than current unit guide wear plates.

Abstract: A brake beam wear plate assembly for a railway car truck sideframe is provided. A brake beam wear plate is provided and adapted to be inserted in a brake beam guide which is typically an integral component of a railway car truck sideframe. The brake beam wear plate itself is comprised of a channel shaped body having an upper wall, a lower wall, and a bottom wall. The brake beam wear plate is typically comprised of a polymer or a high density plastic. The brake beam wear plate also includes a projecting locating tab and the brake beam guide itself includes a complimentary cutout section.

Abstract: A brake assembly for a mobile machine is disclosed. The brake assembly may have a stationary spindle, and a main brake housing annularly connected at a first axial end to the stationary spindle and at least partially forming a first control chamber. The brake assembly may also have a park brake housing annularly connected to a second axial end of the main brake housing and at least partially forming a second control chamber, and at least one piloting feature disposed between an inner annular surface of the park brake housing and an outer annular surface of the stationary spindle.

Abstract: A brake beam wear liner for receiving a brake beam assembly of a railway car truck includes a base wall having an inner surface and an outer surface extending between opposite side edges, and having a base wall thickness between the inner surface and the outer surface thereof. The brake beam wear liner also includes sidewalls extending from the opposite side edges. The sidewalls have inner surfaces and outer surfaces, and have a sidewall thickness between the inner surface and the outer surface thereof. The inner surfaces of the sidewalls and the inner surface of the base wall define an open ended trough configured to receive an end of the brake beam assembly. The brake beam wear liner also includes flanges extending outward from the sidewalls. The flanges have inner surfaces and outer surfaces, and have a flange thickness between the inner surfaces and the outer surfaces thereof. The base wall thickness is greater than the sidewall thickness.

Abstract: There is provided a protection clip for a torque receiving part. The protection clip is fitted into a concave portion of a torque receiving part of a caliper body, into which a lug part of a brake pad of a disc brake is inserted. The protection clip includes first and second separation preventing claws. The first separation preventing claw is bent from an outer periphery-side wall surface of the concave portion toward an upper attaching surface of the torque receiving part, and is configured to be fitted into one of a pair of recesses formed over an opening of the concave portion. The second separation preventing claw is bent from a lower attaching surface of the torque receiving part toward the concave portion, and is configured to be fitted into the other of the pair of recesses.

Abstract: A brake beam wear liner for receiving a brake beam assembly includes a base wall extending between a rear end and front end. The base wall has opposite side edges. The base wall has a tapered thickness between the rear end and the front end with the base wall being thicker proximate to the rear end and being narrower proximate to the front end. The brake beam wear liner also includes side walls extending from the opposite side edges and flanges extending outward from the side walls generally opposite the base wall. The side walls and the base wall define an open ended trough configured to receive an end of the brake beam assembly.

Abstract: A spare brake beam for railway cars which can be quickly and easily installed in a train car without the necessity of cutting the car from the train nor dismantling the car nor the truck.

Abstract: A truck mounted brake beam including at least a primary beam having a center section and a pair of end sections with guide feet. The center portion may include two opposed channel elements, each having a horizontal base and two vertical walls, joined by fasteners or weldments. The weldments are hollow and the bases include openings to the hollow of the weldments. The cross-section of the end portions of at least one of the channeled elements is smaller than the cross-section of a center portion of the at least one channeled element. A method of making a beam brake beam, comprising: obtaining two channeled elements each having a base and two vertical walls; separating an end portion of one of the walls from the base; removing a section of the base adjacent the separated wall; attaching the separated end to the end of the base; and, permanently joining the channeled elements.
