The support has an opening through which the brake lining can be inserted or removed.EFFECT: enhanced reliability.13 cl, 15 dwg

Damping rotor for disk brake // 2260725
FIELD: mechanical engineering.SUBSTANCE: surface of the rotor is subjected to electric-spark grinding or electro-erosion treatment. The part of the rotor of the braking mechanism to be treated by electro-erosion is made of a conducting material, preferably of ferrous metal, iron, and gray cast iron. The braking disk of the rotor is solid or ventilated.EFFECT: enhanced reliability.60 cl, 4 dwg

Disc for clasp brake // 2260151
FIELD: mechanical engineering.SUBSTANCE: disc has assembly bulge for fastening to nave of transportation vehicle wheel and back band connected with bulge and having opposite surfaces of braking to provide interaction with brackets of brake's support to have an breaking effect onto transportation vehicle. At least one braking surface has at least one pair of channels, which have to be reflectively symmetrical to radius of disc. Channels pass in such a manner to embrace the whole thickness of back band, which intends for interaction with brackets. Continuity of each channel is provided along its total length. All four channels of at least one pair of channels pass the route which has at least one straight part and one curved part. Each channel of any pair of channels has at least a part of its route, which is located close to inner edge of back band and is oriented at radial direction mainly. Moreover mentioned channels of at least one pair of channels do not cross each other. All four channels pass the route without being damaged. Any channel passes the route from head or inner end to tail or inner end. The end mentioned is closed with dead edge where side walls of channel connect to each other.EFFECT: improved efficiency of operation; improved reliability of operation of baking system.27 cl, 7 dwg

Ventilated disk for disk brake // 2253057
FIELD: transport mechanical engineering.SUBSTANCE: ventilated disk comprises friction ways connected with the bearing hub of the disk through connecting members made of studs distributed over the periphery of the bearing hub of the disk. One end of the stud is provided with a gripping device embedded in the material of the friction way. The opposite end of the stud is made of an insert which slides in axial direction in the material of the bearing hub of the disk. The friction ways and bearing hub of the disk are cast with the use of the common casting rod with studs.EFFECT: improved performance.7 cl, 7 dwg
