Friction management brake shoe |
摘要 |
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.
