Abstract: A block for wheel brakes comprising a friction portion, in which a friction surface is defined, which, in use, acts upon a peripheral surface of a wheel in order to carry out the braking action, a support plate, which is fixed, in an irreversible manner, to a surface of the friction portion opposite the friction surface, and a base plate, which is fixed to the support plate and comprises a coupling element to fix the block as a whole to a brake system. The block comprises at least one elastic element placed between the support plate and the base plate. The presence of the elastic element creates a ventilation air space between the support plate and the base plate.

Abstract: A brake shoe without a metal backing has a metal insert comprising two spaced apart bodies, a connecting portion having a back face adjacent to the back surface of the brake shoe, and two generally parallel radially extending flanges integral with the connecting portion. The parallel extensions define a keyway, wherein when the brake shoe is emplaced on the brake head, the keyway extends through an opening provided in the brake head.

Abstract: A railroad brake shoe has a pad has a central axis with an arcuate front face which terminates at upper and lower edges. Normal forces at an edge define a line of action. The pad includes support material on the side of the line of action opposite the central axis. The support material resists edge chipping and the formation of edge cracks.

Abstract: The present invention provides a friction management brake shoe adapted to engage the tread and the flange of a railroad car wheel via which the railroad car is guidably supported on a railed track. The friction management brake shoe comprises a backing plate having a flange member. There is a brake lining affixed to the backing plate and having a braking surface engageable with the wheel tread of a railroad car wheel. The brake lining includes a first friction composition material formed with at least one of a solid high positive friction modifier and a solid very high positive friction modifier which establishes a required friction level between the wheel tread and the railed track for stopping a train. The brake shoe also has a flange part affixed to the flange member of the backing plate, such flange part having a friction surface engageable with the wheel flange of a railroad car wheel. The flange part includes a second friction material formed with a solid low coefficient of friction modifier which establishes a friction level of between about 0.08 and 0.15 at an interface between the wheel flange and the railed track.

Abstract: A brake shoe is adapted to engage the tread of a railroad car wheel via which the railroad car is guidably supported on a railed track for conditioning such car wheel thereby affecting adhesion between such wheel tread and railed track. Such brake shoe comprises a backing plate and a brake lining affixed to such backing plate. Such brake lining has a braking surface engageable with a wheel tread and further comprises a first and a second segment disposed on opposite sides of a midpoint of a key bridge of the hacking plate. There is a first material in the form of a friction composition suitable for braking such railroad car wheel. The first material is formed on each of the first and second segments and there is a second material dissimilar from the first material. The second material is disposed as an at least one discrete insert in the first material, such second material conditions the railroad car wheel tread so as to affect adhesion between said wheel tread and the railed track. The second material has a wear rate dissimilar to that of the first material.

Abstract: A backing plate for a railroad brake shoe includes side edges, ends, and an integral lug section located remote from the ends. The backing plate has a generally convex top surface, a generally concave bottom surface, and a longitudinal axis. Located transverse to the longitudinal axis, the lug section has an arcuate shape with an apex and legs and has a plurality of reinforcing members which are integrally formed as part thereof. The apex of the lug section forms a key or lug slot for insertion of a key which secures the backing plate to a brake head. The reinforcing members can take the form of at least one reinforcing rib which is laterally spaced from the lug slot and extends generally parallel to the longitudinal axis of the backing plate. The reinforcing member may also be comprised of an offset portion. Bores may be located on the periphery of the backing plate to impart additional strength thereto.
