US Classification:

188235, 188250 B, 188250 R

Abstract:

Disclosed is an end stabilized backing plate for an extended length brake shoe for use in a railway braking system. The backing plate includes an elongated main portion extending along a longitudinal axis. This main portion has a front face, a back face, a first end portion and an opposed second end portion. A first and second pair of tab members are provided on each of the first and second end portions. These tab members extend in a substantially perpendicular direction with respect to the main body and function to stabilize the end portions of the extended length brake shoe which extend beyond the length of a brake head and reduce and/or eliminate cracking of these end portions of the brake shoe. A method of stabilizing end portions of an extended length brake shoe is also disclosed.

US Classification:

188/25100A, 188/25000B, 188/26400R

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.

US Classification:

188/252000, 188/25100A, 188/26400B

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.

International Classification:

F16D065/04

US Classification:

188/25000B

Abstract:

A brake shoe for use on a railway vehicle for reconditioning a wheel tread surface during a normal braking application including a backing plate and a first friction material extending over the brake surface of such brake shoe. It further contains a second friction material, formed as a discrete insert molded into such first friction material. Such second friction material initially is completely embedded. One surface of the insert is incrementally exposed as the first friction type material is eroded away. Such second friction material exhibits abrasive properties and is bonded to such backing plate. A third friction material is disposed as another discrete insert imbedded in the first friction type material. One surface of the abrasive third friction material being disposed as part of the brake surface of the brake shoe.

International Classification:

F16D069/00

US Classification:

188/25000R

Abstract:

A brake shoe is used on a railway vehicle for both applying a braking force and simultaneously reconditioning a wheel tread surface of a wheel disposed on such railway vehicle during a normal braking application on such vehicle. The brake shoe comprises a backing plate having a predetermined configuration and a first friction type material formed into a brake shoe and having a predetermined shape. There is a brake surface for engaging a wheel tread having a predetermined configuration and having a predetermined surface area. A second friction type material is formed as a discrete insert, having a predetermined shape and a predetermined width, and molded into first friction type material. One surface of the discrete insert being disposed coincidently as part of the brake surface of the brake shoe. The second friction type material exhibits greater abrasive properties than does the first friction type material.

International Classification:

F16D 65/02
F16D 69/00

US Classification:

188234

Abstract:

The invention is directed to an insert for a backing plate assembly for a composition friction brake shoe. The insert is particularly useful in the formation of a universal brake shoe for use with a trolley car braking system. The insert includes a central member having a first and second set of attachment posts extending from the respective ends thereof. These first and second sets of attachment posts are adapted for securing a first and second backing plate strap, respectively, thereto. A key bridge extends through a back portion of the central member and is configured for attachment to a brake shoe. A flange guide support extends from a side portion of the insert and includes legs defining a channel that runs parallel to the insert. The flange guide support is adapted for contacting a wheel flange to align a brake shoe with the wheel during braking of the vehicle.
