Utility model content
In order to solve an installation location difficult problem for existing triangle Tiebar structure pattern used for rolling stock, the utility model aims to provide a kind of triangle rod assembly and tie-rod type journal box positioning device, and this positioning device structure is simple, and fitting operation is easy.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of triangle rod assembly, comprises leg-of-mutton drag link body, and its constructional feature is, laterally offers at least one I end joint through hole at the I of drag link body end, offers at least two II end joint through holes the II end of drag link body is vertical.
Be below the technical scheme of further improvement of the utility model:
Further, in the through hole of described I end joint, interference is equipped with I end joint; The joint through hole interference of described II end is equipped with II end joint.
Preferably, described I end joint is rubber arthrosis or oscillating bearing; Described II end joint is rubber arthrosis.
Further, the utility model also provides a kind of tie-rod type journal box positioning device, its constructional feature is, comprise the triangle rod assembly as above that is arranged on journal box body bottom, the I end of described drag link body holds arthrodesis on described journal box body by I, the II end of this drag link body by II end arthrodesis on framework.
For the ease of installing, described journal box body is provided with the U-shaped groove that Open Side Down.
By said structure, tie-rod type journal box positioning device described in the utility model as shown in Figure 3, mainly formed by a triangle rod assembly 4 and other appurtenances, triangle rod assembly 4 is made up of as shown in Figure 4 4.2,2,4.1,1 I end joint of 1 triangle drag link body II end rubber arthrosis 4.3, the through hole of the I end of the triangle pull bar body of rod is mutually vertical with the through hole of II end, and I end joint 4.2 can be that rubber arthrosis can be also oscillating bearing.I end joint 4.2 is assemblied in I end through hole with interference fit, and 2 rubber arthrosis 4.3 of II end are assemblied in 2 through holes of II end with interference fit respectively.
Tie-rod type journal box positioning device installation process: first triangle rod assembly II end is inserted in framework groove, by II end binding bolt 5, II end rubber arthrosis 4.3 is fixed on framework; Because journal box body is provided with the U-shaped groove that Open Side Down, now triangle rod assembly I end still can move up and down certain distance with framework vertical, and deflection certain angle up and down, similar with simplex pull rod, correct position to be deflected to, can penetrate I end binding bolt 6, because I end is rubber arthrosis or oscillating bearing, can adapt to certain windup-degree, therefore tighten binding bolt 6 and can realize being connected of triangle rod assembly and journal box body, do not need, by external force or frock, framework is depressed into setting height(from bottom).
Compared with prior art, the beneficial effects of the utility model are:
1, effectively having solved prior art must be depressed into framework installation site and could realize a difficult problem of installing.
2, practicality is good, can realize the different demands of single stage suspension to located lateral rigidity and longitudinal register rigidity by adjusting the vertical, horizontal rigidity in I end joint and the radial rigidity of II end rubber arthrosis.
3, simple in structure, reduce the fixing required multiple parts of I end bearing pin of original design.
4, easy accessibility, has improved the maintainability of axle-box positioning device greatly.
5, safe, the bearing pin of effectively having avoided existing structure the to exist risk that comes off.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
