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.9 cl, 8 dwg

Brake shoe equalizing support // 2323376
FIELD: automotive industry; vehicle disk brakes.SUBSTANCE: one or more brake shoes of disk brake are arranged on fastening plates or on other supports for shoes and/or caliper or like device. Caliper or like device and support for shoes are made for taking up resultant counteracting forces at braking in plane perpendicular to surface of contact between caliper or like device and each support for shoes. Calculated point of action of resultant counteracting forces is within the limits of said surface of contact to provide balancing of brake shoes, thus excluding tendency of turning of shoe supports from caliper or to center of brake. Said calculated point of action of counter acting forces is found from following equation where Heq is perpendicular distance from plane through center of brake disk in which point of action of counteracting forces is found; Ry and Ri are radii from center of brake disk to outer and inner sides of brake shoe; α is angle between line passing through center of brake shoe and center of brake disk and corresponding end of brake shoe.EFFECT: optimization of position of point of action of counteracting force and taking up of counteracting force in one plane.10 cl, 4 dwg

Brake member // 2295661
FIELD: mechanical engineering.SUBSTANCE: brake member comprises ring provided with at least one face ring friction surface made of a carbon material and aspiration grooves made in the friction surface. The aspiration grooves are oriented transversally to the peripheral round contours of the face ring friction surface to define cross-pieces from the side of one of the peripheral round contours. The brake member is provided with additional grooves that are interposed between the cross-pieces of the aspiration grooves and whose exits face the peripheral round contour of the friction surface opposite to the direction of the exit of the aspiration grooves.EFFECT: enhanced reliability and prolonged service life.12 cl, 8 dwg, 1 tbl

Wheeled vehicle // 2273570
FIELD: transport engineering; brake systems of wheeled vehicles.SUBSTANCE: proposed wheeled vehicle contains brake mechanisms, brake mechanism liquid cooling device, stop signaling electric system and windshield washer including reservoir with liquid, pump and pump drive motor electrically coupled with supply source through switch. Washer is furnished with two-position electromagnetic valve whose input is connected with pump, and normally open output, with washer, and normally closed output, with brake mechanism cooling device through normally-closed electromagnetic valve. Electromagnet of two-position valve is connected to stop signaling circuit, electromagnet of normally-closed valve, to threshold device electrically coupled with supply source and brake mechanism temperature sensor, and switch is furnished with electromagnetic switching drive connected to stop signaling circuit. Friction pads are secured on brake disks, and brake shoes are made hollow, with partitions inside. Input of brake shoe space is hydraulically connected with pump of brake mechanism cooling device, and output, with reservoir with liquid.EFFECT: improved efficiency of braking and traffic safety.1 dwg
