FRICTION CONTROLLED BRAKE SHOE

摘要

PROBLEM TO BE SOLVED: To prepare a synthetic material transferring a substance to a wheel and giving a sufficient brake by providing a flange member as a part of a backing plate, and providing a second friction material generating a frictional level in a specific range on the flange member. SOLUTION: This friction controlled brake shoe 10 is provided with a backing plate 2 having a flange member 8, and a brake lining is fitted to the backing plate 2. The brake lining includes a first friction synthetic material containing at least one of a solid high-positive friction modifier and a solid ultrahigh- positive friction modifier 12 generating the frictional level required for stopping a train between a wheel tread and a rail track. A flange section 14 having a frictional face couplable with the flange of the wheel of a railway rolling stock is fitted to the flange member 8 of the backing plate 2. The flange section 14 is formed with a second friction material containing a solid low-friction coefficient modifier generating the frictional level of about 0.08-0.15 on the faying face between the wheel flange and the rail track.
