Rolling stock unit brake cylinder Invention relates to railway transport, particular to brake cylinders with mechanisms for adjustment of clearances between brake shoes and rolling stock wheel rolling surfaces. Cylinder with automatic regulator of clearances comprises case, covers defining the pressure chamber accommodating spring-loaded piston and barometric chamber with rod. Rod extends through pressure chamber cover bore to behind the piston in barometric chamber and is composed by thrust screw of automatic regulator leverage. Spring-loaded nuts are fitted on regulator leverage screw as well as ear to transfer piston force to leverage. Rod end extending from cylinder rear cover has means to secure said cylinder to parking brake. |

Invention relates to railway transport, namely, to railway vehicle braking clamps. Disc brake comprises case, brake plates, brake shoes with plastic linings, leverage with two bell cranks and their hinge pins. Brake discs are secured at both sides of running wheel. Leverage is engaged with brake souse on one side and, on that other side, with controlled pneumatic brake cylinders and springs to pull brake shoes from brake disc. Disc brake is equipped with friction discs fitted on both sides of running wheel, at brake discs ends. Inner friction discs are composed of segments fitted on axles at the case while outer friction discs are composed of segment rings secured by pins at brake disc with plates to connection of segments by screws. Friction discs comprises extra springs fitted at axles to make clearance over friction surface. |

Invention relates to railway transport, particularly, to rolling stock braking equipment. Proposed brake comprises spindle and clevis. Said spindle can displace axially. Said spindle rests on said clevis to prevent spindle turn. First ring gear and second ring gear of said clevis have opposed fixed teeth are coupled with said clevis. Spindle ring gear with teeth of both sides is tightly engaged with said spindle between both said ring gears of the clevis. |

Rolling stock car brake system Invention relates to rolling stock car brake devices for separate braking of every bogie. Brake system consists of two parts, i.e. pneumatic and mechanical. Mechanical part is composed of lever gearing automatic regulator and leverage transmitting brake vertical lever to bogie shoes. Brake of every bogie incorporates cylinder to create pushing force at working stroke to act to vertical lever of said gearing via automatic regulator built in the brake cylinder body. |

Clamp brake is mounted at vehicle comprising body and wheel with brake surface to braking force to be applied to said wheel. Clamp brake comprises brake shoe, brake shoe holder, main clamping body, two support pins and drive. Support pins hold said holder at main clamp body to allow its displacement toward brake surface and therefrom. Drive allows pressing brake shoe to wheel brake surface by aforesaid holder. Said drive comprises diaphragm, drive pressure chamber, piston and connected gear. The latter comprises screws and screw bores made in said piston to receive screws to be screwed in through holder to attach the piston thereto. |

Device to adjust clearance in railway vehicle brake drive Invention relates to railway transport, particularly, to devices intended for adjusting clearance in railway vehicle brake drives. Proposed device comprises driving element, rod arranged displace axially inside the latter, adjusting nut engaged with aforesaid rod via threaded joint without self-locking function, means for engagement of driving element and adjusting nut, coil spring, first engagement and second engagement. Drive element features the shape of sleeve and is arranged to displace axially and to take up braking force acting in braking direction. First engagement comprises surface for engagement arranged on driving element and directed toward braking direction, and appropriate surface for engagement located on adjusting nut. Second engagement comprises surface for engagement arranged on driving element and directed toward braking direction, and appropriate surface for engagement located on adjusting nut sleeve. Adjusting nit sleeve is arranged to displace axially on said nut. |

Brake clamp comprises first braking lever arranged opposite vehicle wheel first friction surface and second braking lever arranged opposite second friction surface. Moving brake shoe is mounted on first braking lever to apply brake force to first friction surface. Brake clamp houses pistons to move moving brake shoe in response to membrane extension and guide frame to guide pistons in direction perpendicular to first friction surface. Moving brake shoe applies uniform brake force to vehicle wheel together with brake shoe secured to second braking lever. |

Automatic regulator for brake rigging Automatic regulator contains body where traction screw with self-releasing thread and spring-loaded jacknut and adjusting nut are installed. On jacknut and in other places of frictional contact, inserts in the form of rubber or composition elastomeric rings are installed. The inserts are locked against axial shifting. Friction factor and rigidity of the said inserts are less than these of body material. |

Train brake mains control device Invention relates to brake system devices designed to control air pressure in train brake mains in emergency. Proposed train brake mains control device contains units to check and control parameters of air pressure in brake mains and unit to transmit and receive check and control information by radio channel to/from locomotive. Said units are secured on last car of train. Pressure transmitters are connected by output to brake mains parameters check and control unit. Input of first transmitter is connected through hose of last car to train brake mains before electromagnetic valve which serves as actuating mechanism of control unit. Input of second transmitters is connected to expansion reservoir with throttling hole installed after electromagnetic valve. Device contains also electromagnetic valve communicating with atmosphere in open state and used as required at braking. Said valve is connected directly to expansion reservoir. |

Railway car bogie brake rigging Invention relates to brake systems of freight cars, namely, to design of brake riggings installed on bogies to transmit force of brake cylinder to brake shoes interacting with wheels. Proposed brake rigging includes vertical levers. Upper part of one of levers is connected with tie-rod of car brake system, and upper part of other lever, with shackle of dead point holder. Lower parts of vertical levers are connected by brace, and in middle parts brake beams are hinge secured being suspended through swinging suspension from brackets of side frames and connected by elastic rod installed parallel to longitudinal axis of bogie. One end of said elastic rod is secured in guide of first brake beam, and other end is mounted in guide of second brake beam for reciprocation. Novelty is that proposed brake rigging is furnished with second elastic rod connecting brake beams in mirror like manner, each elastic rod being provided with limiting head on one end and secured from side of one of brake beams by means of clamp with two coaxial holes feted on elastic rod and arranged inside guide. Bent-on wall of clamp encloses one of webs of brake beam guide and rod head. Elastic rods are installed in parallel on end parts of brake beams between brake shoe and spacer. One rod is secured in guide of first brake beam, and the other, in guide of second brake beam. |
