Abstract
An air spring air intake seat comprises an air intake seat body and is characterized in that pipe openings with conical internal threads are respectively arranged on two sides of the air intake seat body. One pipe opening on one side of the air intake seat body is connected with an additional air cylinder after being connected with a pipeline in threaded mode. The other pipe opening on the other side of the air intake seat body is connected with an air spring differential valve after being connected with the pipeline in threaded mode. The air spring air intake seat is connected with the pipeline in threaded mode, convenient to disassemble and replace, simple and convenient to operate and good in maintainability. The air spring air intake seat not only solves the problem of air intake of a bogie air spring, but also completely considers maintainability and has good application prospects.
Description
Technical field
The utility model relates to a kind of air bellow air inlet seat, belongs to the body construction design field.
Background technology
One of important component part in passenger train running part (bogie truck); Supporting car body; For the traveling comfort that improves passenger in passenger vehicle traveling comfort, the car, the conformability of floor level in the car when keeping empty and load; In recent years, the bogie truck of most of passenger vehicle has adopted air bellow to support the mode of car body.The weight of car body drops on the air bellow of bogie truck through sleeper beam.Air bellow needs inflation, could keep certain working pressure, and this just needs the air intake structure of design from auxiliary chamber (giving the reservoir of air bellow air feed specially) to air bellow.After having a lot of air intake structures and sleeper beam to form at present, be not easy to take out.If air intake structure leaks air, when needing to change, shovel falls the many places weld seam earlier, perhaps changes sleeper beam.Waste time and energy, not only cost is high, also is not easy to realize very much, and is maintainable poor.
Summary of the invention
The utility model technical matters to be solved is, overcomes the above-mentioned shortcoming of prior art, and a kind of air bellow air inlet seat is provided.
In order to solve above technical matters; The air bellow air inlet seat that the utility model provides; Comprise the air inlet seat body, it is characterized in that the both sides of said air inlet seat body are offered the mouth of pipe with circular cone negative thread respectively; Link to each other with supplementary reservoir after wherein a side pipe mouth is connected with pipeline thread, the opposite side mouth of pipe is connected the back and links to each other with the air bellow differential pressure valve with pipeline thread.
Further, the bottom of said air inlet seat body be provided with the sleeper beam lower cover on the breach that matches of the hole shape opened.This breach plays the effect of location, spline.
Air bellow air inlet seat and pipeline be through being threaded, and be convenient to dismounting and change, and simple, convenient, maintainable good.The utility model had both solved the air inlet problem of bogie truck air bellow, had also taken into full account the maintainability of air inlet seat, had good utilization prospect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model air bellow air inlet seat sectional structure scheme drawing.
The specific embodiment
The air bellow air inlet seat of present embodiment; As shown in Figure 1; Comprise air inlet seat body 1; The both sides of air inlet seat body 1 are offered the mouth of pipe with circular cone negative thread respectively, and wherein a side pipe mouth is threaded with (B end) pipeline 2 and then links to each other with supplementary reservoir, and the opposite side mouth of pipe is threaded with (A end) pipeline 3 and then links to each other with the air bellow differential pressure valve.The bottom of air inlet seat body be provided with the sleeper beam lower cover on the breach that matches of the hole shape opened.
Below be the sequence of erection of air inlet seat:
1) after mount pad machines, must do the 1600kPa water test, pressurize 20 minutes must not crack, phenomenon seeps water.Do the 900kPa pressure decay test then, pressurize 20 minutes must not be revealed.
2) mount pad is screwed on the underframe lower cover through the counterbore of bottom.
3) pipe gets into and the mount pad assembling through the slotted hole of opening on the body bolster diaphragm.
4) the outer taper pipe thread of pipe and the endosiphuncular tube screw thread fit on the mount pad.
5) being threaded of pipe and mount pad adopted the sealing of Loctite 577 thread locking adhesives.
6) after the assembling of pipe and mount pad is accomplished, must do the 900kPa pressure decay test, pressurize 20 minutes must not be revealed.
Leakage phenomenon is arranged or need maintenance if run into, as long as bogie truck is removed in unwheeling.
1) can turn on pipe, connect again;
2) unclamp screw on the air inlet seat base plate, take out air inlet seat;
3) mount pad that more renews or pipe.
More than simple, convenient, maintainable good.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
1. air bellow air inlet seat; Comprise the air inlet seat body; It is characterized in that; The both sides of said air inlet seat body are offered the mouth of pipe with circular cone negative thread respectively, link to each other with supplementary reservoir after wherein a side pipe mouth is connected with pipeline thread, and the opposite side mouth of pipe is connected the back and links to each other with the air bellow differential pressure valve with pipeline thread.
2. according to the said air bellow air inlet seat of claim 1, it is characterized in that: the bottom of said air inlet seat body be provided with the sleeper beam lower cover on the breach that matches of the hole shape opened.
