Abstract
The utility model discloses a kind of air spring and add mat structure.Described air spring adds mat structure and includes for installing air spring architecturally；Equipped with utilizing propulsive thrust jack-up air spring to form the thrust reverser mechanism in cushioning space between the base and framework of air spring on the base of air spring.The how problem of cushioning under air spring of adding when mat structure especially solves the equipment not having space mounting jack-up air spring below air spring alignment pin of the present utility model.
Description
Technical field
This utility model relates to a kind of air spring and adds mat structure, belongs to rail vehicle auxiliary equipment field.
Background technology
Air spring is a kind of to utilize compressed air as a kind of form of springs of elastomer, currently mainly applies in the secondary suspension system of city rail vehicle and EMUs.Owing to needing to ensure the vehicle floor face height after wheel wear, then need to add pad below air spring.
It is body framework that tradition adds pad mode, then cushioning below air spring.This method inconvenient operation.
Chinese patent ZL200920259227.2 discloses one and adds mat structure, and it, by arranging a circular hole below the location of air spring, when needing cushioning, inserts a guide rod, and guide rod of jack-uping can complete cushioning, it is not necessary to unwheeling.This method has benefited from below air spring the installing space not having miscellaneous part to take guide rod.If guide rod is blocked by truck transom pipe, this pad mode that adds just cannot be suitable for.
Utility model content
This utility model aims to provide a kind of air spring and adds mat structure, and this adds when mat structure especially solves the equipment not having space mounting jack-up air spring below air spring alignment pin the how problem of cushioning under air spring.
To achieve these goals, this utility model be the technical scheme is that
A kind of air spring adds mat structure, including for installing air spring architecturally；It is structurally characterized in that, equipped with utilizing propulsive thrust jack-up air spring to form the thrust reverser mechanism in cushioning space between the base and framework of air spring on the base of air spring.
Thus, the base being made air spring by thrust reverser mechanism forms cushioning space between the base and framework of air spring relative to moving on framework, it is simple to cushioning.After cushioning, thrust reverser mechanism is unloaded.
According to embodiment of the present utility model, it is also possible to make this utility model further to optimize, below for the technical scheme formed after optimizing:
Preferably, described thrust reverser mechanism includes the multiple tapped through holes being vertically arranged being opened on the base of air spring, at each tapped through hole built with the bolt utilizing propulsive thrust that described air spring is formed between air spring base and framework cushioning space relative to framework jack-up.Thus, during solving air spring cushioning, need not erect car body or bogie of dismantling, air spring base is offered two or more screwed hole, offering of screwed hole needs the carrying center of guarantee air spring need to fall on the line of screwed hole or in the polygon of screwed hole line composition, then in screw thread, it is screwed into screw bolt jack-up air spring, then adjusts the height of air spring by adding pad below air spring.
Certainly, described thrust reverser mechanism can also is that screw-nut body, core point are, by counter pushing away, air spring jack-up is formed cushioning space.
Preferably, described tapped through hole is two, and the center of gravity of air spring is positioned at the perpendicular that the centrage of two tapped through holes is formed, thus, it is possible to ensure to ensure the balance of air spring when anti-pushing and withstanding plays air spring.
Described tapped through hole is more than three, and the center of gravity of air spring is positioned at, in the projection of horizontal plane, the polygonal region that the projection in the horizontal plane of tapped through hole centrage is formed, thus, it is possible to ensure to ensure the balance of air spring when anti-pushing and withstanding plays air spring.
Place pad for convenience, have for by the groove of bolt for the pad being placed in cushioning space.It is highly preferred that described pad has U-type groove.
Compared with prior art, the beneficial effects of the utility model are: this utility model need not unwheeling, easily operate, and provide cost savings, and are particularly suited for below air spring alignment pin the occasion during equipment not having space mounting jack-up air spring.
Below in conjunction with drawings and Examples, this utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of one embodiment of this utility model.
Detailed description of the invention
A kind of air spring adds mat structure, as shown in Figure 1, the base 2 of air spring 1 offers screwed hole 5, the polygon of the line of screwed hole 5 or screwed hole 5 line composition ensures that the carrying center of air spring falls on this line or in polygon, and this structure thoroughly solves and installs the occasion that jack is limited.
When needing cushioning, by being screwed into bolt 3 in screwed hole 5, produce support force between bolt 3 and framework 6 and support air spring, leave the cushioning space 7 installing pad 4.Then the pad 4 i.e. height of adjustable air spring of U-type groove is had by addition.After pad 4 installs, bolt 3 of reversely back-outing.
The content that above-described embodiment illustrates should be understood to that these embodiments are only used for being illustrated more clearly that this utility model, rather than limit scope of the present utility model, after having read this utility model, those skilled in the art each fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
