Technical field
The utility model relates to rolling stock, refers to that particularly a kind of to be used at gauge be the dual brakes system system narrow gage railway box car that moves on the 1067mm circuit.
Background technology
At present, box car in the world has 30t, 50t, 60t, 70t level box car by load carrying ability classification, and gauge is arranged is the standard gauge box car, gauge of 1435mm greater than the broad gauge box car of 1435mm, the gauge narrow gauge box car less than 1435mm by gauge type branch.The load carrying ability of box car is big more, and its gauge is wide more, and the brake equipment that is adopted is also different.Generally speaking, load carrying ability is at the vacuum brake equipment often of 50t or the outfit of the narrow gauge box car below the 50t, and load carrying ability is at the air brake equipment often of 50t or standard gauge more than the 50t or the outfit of broad gauge box car.For example, in South East Asia and area, Africa, gauge is generally narrower, the railroad track in area, Africa is the narrow gauge of 1067mm, and the railroad track of south east asia part country is a meter rail, and box car mostly adopts vacuum brake equipment, vehicle load is below 50t, and running velocity is lower than 80 kilometers.In developed countries such as America and Europe, Japan, box car mostly adopts air brake equipment, and vehicle load is more than 70t, and running velocity is up to 120 kilometers.In China, railway is the standard distance of 1435mm, has load carrying ability to be respectively all kinds of box cars of 30t, 50t, 60t, 70t level, and the box car below 50t or the 50t is too little because of load carrying ability, can not adapt to China's needs of economic development.
The rolling stock vacuum brake equipment be a kind ofly early occur, relatively backward brake equipment, can not adapt to the requirement that the weight of train increases and speed improves, will progressively eliminate by stages, the substitute is the air brake equipment of performance requriementss such as can satisfying train speed raising, heavy duty, period of inspection and repair length.But present stage two kinds of brake mode vehicle and deposit, brought difficulty to coupling of vehicles marshalling, if the vehicle that adopts vacuum brake equipment is transformed, will inevitably expend a large amount of vehicle technology improvement costs again, lose more than gain.Thereby, need a kind of vehicle that has vacuum brake and two kinds of brake mode of air brake simultaneously in a period of transition, it can be satisfied and the existing coupling of vehicles marshalling of adopting vacuum brake equipment, can satisfy again and the coupling of vehicles marshalling of adopting air brake equipment in the future.
Summary of the invention
The purpose of this utility model be to provide a kind of be applicable to operation on narrow gage railway, simultaneously have two kinds of brake mode of vacuum and air, can satisfy the dual brakes system system narrow gage railway box car that coupling of vehicles mixes the marshalling needs.
For realizing this purpose, the dual brakes system system narrow gage railway box car that the utility model is designed, comprise car body, be lifted on air brake equipment, vacuum brake equipment and hand brake device on the car body underframe, the forward and backward narrow gauge bogie truck of supported cart running body, and the coupler and draft gear that is arranged on the car body end.
The shared cover braking leverage of above-mentioned air brake equipment, vacuum brake equipment and hand brake device, this overlaps shared braking leverage by forward and backward brake lever, brake slack adjuster, forward and backward top rod constitutes.The two ends of brake slack adjuster are hinged on respectively on the intermediate support of forward and backward brake lever, the push rod of the one side force arm end of front brake lever and the sealing brake cylinder of air brake equipment is hinged, the same side arm of force end and a fixed bearing of back brake lever are hinged, the opposite side arm of force end of forward and backward brake lever is hinged with forward and backward top rod respectively, and the other end of forward and backward top rod links to each other with the foundation brake rigging of forward and backward narrow gauge bogie truck respectively.
The lever connection of above-mentioned vacuum brake equipment is also hinged with a side force arm end of above-mentioned front brake lever, the other end of lever connection then is hinged on the end of vacuum brake axle of vacuum brake equipment fixedly on the fork, and the vacuum brake axle links to each other with the push rod of the vacuum brake cylinder of vacuum brake equipment by the center fixed fork.
Above-mentioned hand brake device respectively is provided with a cover in I, the IV parallactic angle of car body, and the hand brake device that is located at the I parallactic angle directly is hinged on the fixedly fork of vacuum brake axle by connection arm-tie, pull bar; The hand brake device that is located at the IV parallactic angle then is hinged on the fixedly fork of vacuum brake axle by connecting arm-tie, pull bar, break-in lever and reverse pull bar.
The utlity model has following advantage: one, adopted this two covers brake system of air brake equipment and vacuum brake equipment on the box car car body simultaneously, avoided when adopting advanced air brake technology, the existing vehicle of vacuum brake equipment that adopts is transformed, saved a large amount of existing vehicle technology improvement costs.Its two, the pilot piping part of air brake equipment that is adopted and vacuum brake equipment is separate, the brake lever components of system as directed is shared, and is simple and compact for structure, the parts that adopted are few, can effectively reduce manufacturing cost.Its three, box car car body two ends respectively establish one the cover hand brake device, all can implement hand braking, convenient and practical to vehicle at arbitrary end of vehicle.Its four, have the box car of air brake equipment and vacuum brake equipment simultaneously, can with the existing coupling of vehicles marshalling of adopting vacuum brake equipment, again can with the coupling of vehicles marshalling of adopting air brake equipment, significantly improved the conveying efficiency of box car.
