Description
Technical field
The utility model relates to a kind of anti-side rolling torsion rod mounting structure being applicable to articulated bogie.
Background technology
In rail traffic vehicles, for regulating vehicle floor face height and obtaining horizontal and vertical performance preferably, rail traffic vehicles generally adopts air bellow to support between bogie truck.In this context, guideway vehicle usually between bogie truck and car body center a set of torsion bar mechanism for preventing side rolling of train carriage is set, to suppress car body relative to the motion of bogie truck.Anti-side rolling torsion rod and mount pad are the important links between bogie truck and car body, have higher requirement of strength.
Because articulated bogie has more advantage relative to conventional bogie, increasing guideway vehicle tends to use articulated bogie.The position of articulated bogie, generally between two joint compartments, because of the change of the connection location of bogie truck and car body, causes link therebetween to change accordingly.One of them needs the installation site just having anti-side rolling torsion rod changed.
Traditional mode installs a set of anti-side rolling torsion rod in the middle of bogie truck; Need now installation two to overlap anti-side rolling torsion rod at bogie truck two ends, connect the compartment that two joints are different respectively.Therefore, corresponding mount pad and anti-side rolling torsion rod mounting structure will be designed, to solve the connectivity problem of anti-side rolling torsion rod and bogie truck and car body.
Utility model content
For solving the anti-side rolling torsion rod of articulated bogie and the connectivity problem of bogie truck and car body, the utility model aims to provide a kind of safe and reliable anti-side rolling torsion rod mounting structure.
The technical scheme that the utility model is dealt with problems is: a kind of anti-side rolling torsion rod mounting structure being applicable to articulated bogie, comprise the T slot at edge beam of underframe C shape groove, edge beam of underframe C shape groove top, also comprise and be installed on slide block in T slot and the chimeric mount pad be arranged in the C shape groove of edge beam of underframe, the slide block in the top of mount pad and T slot removably connects;
Mount pad lower end is connected with the connecting rod of torsion bar mechanism for preventing side rolling of train carriage.
As a kind of concrete mode, mount pad and slide block are bolted; Described slide block can move in T slot, slide block at least has a stepped hole, and the first order hole of this stepped hole is identical with bolt cap shape and size is greater than bolt cap external diameter, and the aperture in hole, the second stage is greater than the screw diameter of bolt and is less than bolt cap external diameter;
Mount pad top has the through hole corresponding with the stepped hole of slide block, and bolt is inserted through the through hole of mount pad upper top from the stepped hole of slide block, by mount pad and slide block fastening.
Described mount pad cross-sectional plane is inverted U-shaped, and vertical portion lower end, mount pad both sides respectively horizontal expansion is provided with flange, and described flange is provided with tapped bore, the connecting rod of torsion bar mechanism for preventing side rolling of train carriage by bolt and tapped bore fastening.
As the further improvement of such scheme, be provided with sleeve between flange and connecting rod, this sleeve set is at the screw rod of the bolt for flange connector and connecting rod.The object arranging sleeve is: the predetermincd tension can strengthening the bolt for flange connector and connecting rod first; Second the gap between mount pad and connecting rod can be adjusted, in order to avoid interfere therebetween.
For ensureing working accuracy and the intensity of mount pad, described mount pad adopts integrated mode to make.Abandoning welded structure is motion due to the relative bogie truck of car body in operation process, and the reversed fatigue stress that connecting rod produces causes the problem of weld cracking.
For making the weight of mount pad little as far as possible, the non-bearing part of the both sides vertical portion of described mount pad has oblique angle, to excise excess stock.
Further, for ensureing assembly precision, the through hole at described mount pad top is waist shaped hole, reduces adjustment assembly error to facilitate.
Stepped hole on described slide block is provided with three; Accordingly, the through hole at described mount pad top is provided with three.
Preferably, the material of described mount pad is 42CrMo, and this ultra-high-tensile steel is enough to the intensity and the reliability that ensure mount pad.
The utility model devises a kind of brand-new anti-side rolling torsion rod mounting structure, efficiently solves the connectivity problem of anti-side rolling torsion rod and articulated bogie and car body.This structure devises the mount pad that can mate with edge beam of underframe according to the profile structure of edge beam of underframe, be fastened on edge beam of underframe by mount pad, and be connected with mount pad by anti-side rolling torsion rod by slide block.
Adopt the mode that slide block and mount pad are fastening, can be reliable and stable be connected with edge beam of underframe by mount pad, avoid employing tommyhead bolt and cause the problem of insufficient strength.
Mount pad structure is simple, easy for installation, is easy to processing and detects, reliability and maintainable high.
