The utility model discloses a connection assembly of a fulcrum seat and a bogie of a rail wagon. The connection assembly of the fulcrum seat comprises a swing bolster and the fulcrum seat, wherein the swing bolster is provided with a through hole; and the fulcrum seat is fixedly connected with the through hole of the swing bolster through a fastening member, or the fulcrum seat and the swing bolster are integrally cast and formed. By the technical scheme provided in the utility model, the fulcrum seat and the swing bolster can be connected through the through hole and the fastening member, or the fulcrum seat and the swing bolster are integrally cast and formed, therefore, the welding is avoided, and the influence on the life of the swing bolster is reduced.
Description
Technical field
The utility model relates to the railway truck structure technology, relates in particular to a kind of fulcrum block coupling assembling and railway goods train bogie.
Background technology
The dead lever fulcrum seat is a part on steering frame swing bolster of lorry is formed, the effect that the dead lever fulcrum seat is set is that the lever for the truck brake rigging device provides a fixing fulcrum, in order to guaranteeing vehicle in the release of brake process, the lever of foundation brake rigging have an attachment point can around rotation.Existing dead lever fulcrum seat directly is welded on the bolster on plane or the bolster sidewall, because when assembling, need weld, thus influence the fatigue life of bolster, and poor working environment.
Fig. 1 and Fig. 2 are the structural representation of existing fulcrum block coupling assembling.Existing dead lever fulcrum seat 2 fits together by plane on welding and the bolster 1 or bolster 1 sidewall, in order to guaranteeing vehicle in the release of brake process, the lever of foundation brake rigging have an attachment point can around rotation.There is following defective in dead lever fulcrum seat 2 under the prior art state: could be connected with bolster 1 after existing dead lever fulcrum seat 2 must weld, because of the welding scope bigger, and near main force part, influence the fatigue life of bolster 1, and produce a large amount of noxious gases, poor working environment in the welding process; Dead lever fulcrum seat 2 is welded on the bolster 1, removes difficulty during maintenance; Most of dead lever fulcrum seat 2 is not to be welded on the center of symmetry, when needing as shown in Figure 1 position and its that side position is installed simultaneously, then needs two bolster 1 to form, and dead lever fulcrum seat 2 is the mistake dress easily.

The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of fulcrum block 2 coupling assemblings, its structure can be referring to shown in Fig. 3 A-6, fulcrum block 2 coupling assemblings comprise bolster 1 and fulcrum block 2, and wherein: offer through hole on the bolster 1, fulcrum block 2 is captiveed joint with the through hole of bolster 1 by fastener 6.Concrete, can directly be provided with fastener 6 on the fulcrum block 2, also another through hole can be set, fastener 6 is connected fulcrum block 2 and bolster 1 by separately through hole on bolster 1 and the fulcrum block 2.
Preferably through hole is a screw 4, and fastener 6 is bolt or screw.
The technical scheme that the utility model embodiment is provided adopts bolted mode to assemble dead lever fulcrum seat 2, need not weld, and adopts bolt connecting mode just can carry out the assembling of bolster 1 and fulcrum block 2.Directly dead lever fulcrum seat 2 is connected on the bolster 1 by bolt, has avoided welding job, alleviated bolster 1 Fatigue Life, and improved working environment.And the utility model is removed difficult shortcoming at existing dead lever fulcrum seat 2, has adopted bolt connecting mode, and 2 need of dead lever fulcrum seat unscrew nut and can take off dead lever fulcrum seat 2, so remove easily.
On the basis of technique scheme, preferably, the quantity of through hole is a plurality of, is separately positioned on a plurality of positions of installing for fulcrum block 2.Preferably dead lever fulcrum seat 2 assembling through holes are all left in bolster 1 two side.Perhaps, specifically can be with position design plane or bolster 1 side-walls on bolster 1 of dead lever fulcrum seat 2.Further, through hole is at bolster 1 with respect to the longitudinal axis of bolster 1 and is symmetrical arranged or asymmetric setting.This technical scheme is not a situation about being welded on the center of symmetry at most of dead lever fulcrum seat 2, on bolster 1 two side, all keep the position that dead lever fulcrum seat 2 is installed through hole, can assemble dead lever fulcrum seat 2 as required at any time, adjust even if the mistake dress is also convenient.
By the enforcement of technique scheme, both can avoid adopting welding manner to assemble, can make things convenient for the dismounting of dead lever fulcrum seat 2 again, can also prevent the mistake dress of dead lever fulcrum seat 2 simultaneously to a certain extent.
The technical solution of the utility model, bolted connection formula dead lever fulcrum seat 2 changes existing dead lever fulcrum seat 2 needs welding to carry out the stack-mounted mode, adopted bolted mode to assemble, choose quantity, size and the distance of suitable bolt hole according to actual needs, and height as required and apart from bolster 1 centre distance determine between pin hole 5 centers and two screw 4 lines distance, angle and and assembling face between distance.So-called pin hole 5 is the mounting holes that are used to install lever.Angle between dead lever fulcrum seat 2 pin hole, 5 centers and two screw 4 lines can be adjusted.
Bolted connection formula dead lever fulcrum seat 2 assembly drawings as shown in the figure, the auxiliary hole of assembling binding bolt is reserved in casting during bolster 1 thereon on plane or the sidewall, adopts bolt to be connected plane on dead lever fulcrum seat 2 and the bolster 1 or sidewall also fastening.
In the utility model, through hole can also be unthreaded hole, and fastener can also be rivet or pin etc.Technique scheme also need not be welded, adopt rivet hot nail or pulling rivet or staking pin connection mode to assemble, riveted joint interconnection system dead lever fulcrum seat can directly be connected the dead lever fulcrum seat on the bolster by rivet, avoided welding job, alleviated the bolster Fatigue Life, and improved working environment.
Riveted joint interconnection system dead lever fulcrum seat only need be unriveted and can be taken off the dead lever fulcrum seat, and convenient the adjustment and maintenance removed easily.
The position that all keeps dead lever fulcrum seat mounting hole on the bolster two side can be assembled the dead lever fulcrum seat as required at any time, adjusts even if the mistake dress is also convenient.
The utility model embodiment also provides another kind of fulcrum block coupling assembling, comprises bolster and fulcrum block, wherein: fulcrum block and the moulding of bolster integrally casting.This technical scheme can be as required height, directly on bolster, cast out the dead lever fulcrum seat apart from requirements such as centre distance, angles of inclination.Also need not welding, avoid influence the bolster life-span.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
