The specific embodiment
Referring to Fig. 2 a and Fig. 2 b, the embodiment of the invention one provides a kind of column wearing plate, is used to be installed in the bogie side frame of bogie truck, and particularly, the bolster that is installed in bogie side frame is blocked.It comprises bottom land 51 this column wearing plate 5, and two ledges 52 that on bottom land 51, are oppositely arranged, and bottom land 51 and two ledges 52 form spills, and spill is used to coat the bottom surface and the side of bolster retaining.
The shape of bottom land depends on the bottom shape of bolster retaining, and in the prior art, the bottom surface of bolster retaining is generally rectangle, and bottom land also is a rectangle.Two ledges are oppositely arranged on two rectangular edges of bottom land, and whole column wearing plate is spill.Two ledges can be symmetricly set on the bottom land, also can be asymmetric, get final product so long as can be arranged on the side of bolster retaining.
Fixing between column wearing plate and the bolster retaining can be adopted following mode, and a kind of mode is that ledge and bolster retaining is fixing, and another kind of mode is that bottom land and bolster retaining is fixing.If adopt ledge fixing with the bolster retaining, adopt snap-in fixing more conveniently, particularly, be that two ledges directly are stuck on two sides of bolster retaining, certainly, also can adopt bolt, riveted and fixed or weld and fix.If adopt bottom land and bolster retaining fixing, can still adopt discount bolt of the prior art.
After ledge was set, the ledge retaining was on the side of bolster retaining, to play the effect that prevents that bolster retaining side is worn; In addition, ledge is set after, ledge plays certain restriction to bottom land, bottom land is not prone to warpage or breakage problem, has improved the service life of column wearing plate.
Preferably, each ledge 52 all is 90 degree with the angle of bottom land 51., can adopt following mode to form ledge and bottom land here, with two ends bending 90 degree of a square shaped steel plate, kink forms ledge, and the part that is not bent forms bottom land.The column wearing plate of said structure, compact conformation, it is convenient to make.
Referring to Fig. 2 a and Fig. 2 b, further, offer opening 53 on each ledge 52, opening 53 is used for fixing with the side of bolster retaining.Particularly, can keep off at bolster protruding location retaining is set on the side, opening 53 is stuck in this location and blocks, and to realize fixing between ledge and the bolster retaining side, the cooperation between opening 53 and the location retaining is for closely cooperating, such as transition fit or interference fit.Ledge can be referring to Fig. 3 a and Fig. 3 b with the scheme drawing that is connected between the bolster retaining.Fixed form with respect to using the discount bolt in the prior art offers opening on ledge, easy through the fixed form operation of open card on the side of bolster retaining; And Assembly &Disassembly is all very convenient; Discount bolt cost is high, uses cassette to fix, and need not to re-use the discount bolt.
The material of bottom land 51 and ledge 52 can be 0Cr18Ni9 corrosion-resistant steel or No. 45 steel, the bottom land 51 and ledge 52 long service life of above-mentioned material, and integrally-built good stability.
The column wearing plate that the embodiment of the invention one provides has ledge, and in the use, ledge is arranged on the side of bolster retaining, to work the purpose of the flank wear that prevents the bolster retaining; Adopt snap-in fixing between ledge and the bolster retaining, can avoid the use of the discount bolt, reduced productive costs, and be convenient to dismounting.
Fig. 3 a is the local structure scheme drawing of the bogie truck that provides of the embodiment of the invention two, and Fig. 3 b is that the B of Fig. 3 a is to view.The embodiment of the invention two provides a kind of bogie truck; Have bolster (scheming not shown) and two bogie side frames 1; Each bogie side frame 1 is provided with the bolster retaining 2 that is used to limit the bolster position, wherein, on the bolster of at least one bogie side frame 1 retaining 2 the described column wearing plate 5 of any embodiment of the present invention is installed.
After the installation, the column wearing plate is between bolster retaining and bolster.In the vehicle operating process, the ledge of column wearing plate irregularly contacts with bolster, and after using this column wearing plate on the bogie truck, the ledge of column wearing plate can effectively prevent the flank wear of bolster retaining.
Preferred immobilization mode between bolster retaining and the column wearing plate does, is formed with the location retaining 6 of evagination on the side of bolster retaining 2, and the opening 53 on column wearing plate 5 ledges 52 is stuck on the location retaining 6.The said fixing mode is simple and reliable, in the time of dismantling the column wearing plate, only needs to use crowbar that the column wearing plate is blocked to prize from the location and gets final product.
In the practical application, bolster retaining 2 can integrally casting moulding, bonded assembly reliability height between bolster retaining 2 and the location retaining 6 like this with location retaining 6.
The bogie truck that the embodiment of the invention two provides, the side of its bolster retaining is provided with ledge, and increase the service life of bolster retaining greatly.Existing for bogie truck of the prior art, bogie truck provided by the present invention is longer service life.
The embodiment of the invention also provides a kind of rail freight, and it comprises the described bogie truck of any embodiment of the present invention.The rail freight that the embodiment of the invention provides, its bolster retaining is longer service life, has reduced owing to changing expensive that bogie side frame causes.
What should explain at last is: above embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although with reference to previous embodiment the present invention has been carried out detailed explanation, 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 are revised or replacement, do not make the scope of the essence disengaging various embodiments of the present invention technical scheme of relevant art scheme.
