DISC BRAKE BLOCK Russian patent published in 2009 - IPC F16D65/92 F16D69/00 B61H5/00 

FIELD: machine building.

SUBSTANCE: invention is related to the field of railway transport, namely to disc brake mechanisms used in railway rolling stock. Brake block consists of frame and friction element that is monolithically connected to it. There are mounting lugs installed on back side of frame. Friction element consists of 1-4 inserts. Inserts are arranged as integral or composite. Integral inserts are installed in frame chambers and are arranged in the form of truncated pyramids with base in the form of trapezoid or polygon that are inverted with their lower base to working surface of brake block, with inclination of side walls of α=10°-15°, with provision of "dovetail" joint to frame chambers. Composite inserts are made of parts, parts are installed in cells of frame chambers and are arranged in the form of truncated pyramids or cones inverted with their smaller base to working surface of brake block with inclination of side walls of α=10°-15°, with provision of "dovetail" joint to cells of frame chambers. Frame material additionally covers internal side walls of integral inserts or internal side walls of composite insert parts. There are windows provided in external side walls of frame, at least on two sides opposite to every insert, and inserts have protrusions that correspond to windows. There are heat resistant elastic damper bushings placed in mounting lugs.

EFFECT: increased heat resistance of block, operational durability, reliability and mechanical strength.
