Abstract

Disclosed is a lorry with a vacuum brake system arranged at the end, which comprises a lorry body, vacuum brake devices and an air brake device. The vacuum brake devices are arranged at one end of the lorry body. The vacuum brake devices are arranged at the end of the lorry body, so the bearing load of the middle part of the lorry body is reduced, thus reducing potential safety hazard during the running of the lorry. The vacuum brake devices are arranged together, which is convenient for repair and maintenance.

Description

Railway truck is arranged in a kind of vacuum brake system end
Technical field
The utility model relates to a kind of railway truck, is specifically related to a kind of vacuum brake system end and arranges railway truck.
Background technology
At present, along with China's international influence increases gradually, middle home made article participates in the competition of world market comprehensively, and the railway product is no exception.The vehicle that operates on Tanzania-Zambia's railway must configuration air brake and two kinds of brake system of vacuum brake.If Pneumatic brake systems and vacuum brake system are arranged in the tank base of no underframe tank car, because the vacuum brake system own wt is very big, add Pneumatic brake systems, make tank body and car body force-bearing situation abominable, in operational process, can have potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of vacuum brake system end to arrange railway truck, and it has solved big, the abominable technical matters of car body force-bearing situation of car body middle part load-bearing in the background technology.
Technical solution of the present utility model is:
Railway truck is arranged in a kind of vacuum brake system end, comprises car body 1, vacuum brake equipment 2 and air brake equipment 3, and its special character is: described vacuum brake equipment 2 is arranged at an end of car body 1.
Above-mentioned vacuum brake equipment 2 comprises 2 vacuum brake cylinders 201,2 double branch pipe release valves 202,2 vacuum reservoirs 203, vacuum hose 204, empty and load change-over cock 205, empty and load adjusting shaft 206, vacuum shaft 207, parking brake lever 208, vacuum is responsible for 209, cut out cock 210 and connecting line 211 is characterized in that: each parts centralized arrangement of described vacuum brake equipment 2 together.
Above-mentioned air brake equipment 3 can also be arranged at car body 1 middle part or the other end.
The utlity model has following advantage:
1, vacuum brake system is arranged at the car body end, alleviates car body middle part load-bearing.
2, vacuum brake equipment adopts centralized arrangement, makes things convenient for repair and maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vacuum brake equipment structural representation;
Fig. 3 is a vacuum brake equipment plan structure scheme drawing.
The drawing reference numeral explanation:
The 1-car body, 2-vacuum brake equipment, 201-vacuum brake cylinder, 202-double branch pipe release valve, 203-vacuum reservoir, 204-vacuum hose, the 205-empty and load change-over cock, 206-empty and load adjusting shaft, 207-vacuum shaft, 208-parking brake lever, the 209-vacuum is responsible for, the 210-cut out cock, 211-connecting line, 3-air brake equipment.
The specific embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, railway truck is arranged in a kind of vacuum brake system end, comprise car body 1, vacuum brake equipment 2 and air brake equipment 3, vacuum brake equipment 2 is arranged at an end of car body 1, referring to Fig. 2 and Fig. 3, vacuum brake equipment 2 comprises 201,2 double branch pipe release valves 202 of 2 vacuum brake cylinders, 2 vacuum reservoirs 203, vacuum hose 204, empty and load change-over cock 205, empty and load adjusting shaft 206, vacuum shaft 207, parking brake lever 208, vacuum is responsible for 209, cut out cock 210 and connecting line 211, each parts centralized arrangement of vacuum brake equipment 2 together, air brake equipment 3 is arranged at car body 1 middle part.
Vacuum pump (air pump) and vacuum brake valve on the locomotive of manipulation vacuum brake train, when vacuum brake activation valve handle places the alleviation position, vacuum pump is communicated with vacuum train pipe, vacuum pump is taken away in the vacuum person in charge 209, the vacuum brake cylinder 201 and the air of vacuum reservoir 203 by vacuum hose 204, the piston rod of vacuum brake cylinder 201 is because deadweight is protruding, lever on the vacuum shaft 207 does not stress, and vehicle is eased.When the train pipe communicates with atmosphere, atmosphere enters the train pipe, enter vacuum brake cylinder 201 bottoms by vacuum hose 204 and connecting line 211, and vacuum brake cylinder 201 tops are to link to each other with vacuum reservoir 203 still to keep vacuum, bar pressure promotion piston rod is upwards withdrawn in the vacuum chamber, give parking brake lever 208 by the lever on the vacuum shaft 207 with brake-force transmission, make vehicle generation brake action thereby be passed to foundation brake rigging at last.
Vacuum brake cylinder 201 directly links to each other with double branch pipe release valve 202, two outlets on the double branch pipe release valve 202, the one tunnel leads to vacuum reservoir 203, another road be responsible for 209 by connecting branch and vacuum and link to each other, form one and overlap vacuum brake mechanism.Two cover vacuum brake mechanisms are responsible for vacuum brake by same connecting branch and are connected, be provided with empty and load change-over cock 205 at this root arm middle part, cut out cock and one road vacuum mechanism can be closed, thereby make braking force reduce the requirement that half adapts to empty wagons, the required braking force of loaded vehicle; This arm and brake pipe junction are provided with cut out cock 210, can close two cover vacuum brake mechanisms.Vacuum is responsible for 209 two ends and is linked to each other with vacuum hose 204.Vacuum brake cylinder 201 piston rods are connected with lever on the vacuum shaft 207, and to vacuum shaft 207, vacuum shaft 207 and then power passed to parking brake lever 208 is passed to foundation brake rigging at last with brake-force transmission.
