Description
Technical field
The present invention relates to railway truck technology, particularly relate to a kind of draught gear supporting seat and coupler and draft gear.
Background technology
Railway truck generally comprises the part compositions such as car body, bogie truck, brake equipment and coupler and draft gear.Wherein, coupler and draft gear is the connecting device between vehicle, and the longitudinal loading can born between vehicle plays buffer action simultaneously.The coupler and draft gear of 70 tonnes and following railway truck comprises hitch 1(16 or 17 type hitches) and the parts composition such as draught gear supporting seat 2, concrete structure is as shown in Figure 1.Wherein draught gear supporting seat 2 is positioned at the below of hitch 1, for supporting hitch 1.
Described draught gear supporting seat 2 comprises wearing plate 3, bearing 4 and is fixed on for supporting the bearing surface 5 of hitch 1 on bearing, as shown in Figures 2 and 3.The wearing plate that described wearing plate 3 is made for steel plate, is welded on the bearing surface 5 of draught gear supporting seat 2.Described wearing plate 3 has following effect: a, prevent bearing surface 5 from wearing away, when goods train vehicle runs, when hitch 1 is subject to longitudinal loading effect generation Tension and Compression, hitch 1 and bearing surface 5 produce abrasion, when bearing surface 5 wears away certain limit, just need to change draught gear supporting seat 2, cause the waste of human and material resources.Draught gear supporting seat 2 bearing surface 5 welds wearing plate 3, the abrasion of draught gear supporting seat 2 bearing surface 5 can be prevented, when draught gear supporting seat 2 wearing plate 3 exceed wear limit, need to change wearing plate 3 in time; B, play the effect of cushion block, the wearing plate 3 by changing different-thickness adjusts the height of hitch 1, to ensure the requirement of vehicle to hitch 1 height.
There is following shortcoming in existing draught gear supporting seat 2: a, wearing plate 3 are easy to wear, and existing wearing plate 3 adopts steel plate to make, and abrasion resistance is poor, and examine and replace is frequent, wastes a large amount of human and material resources; B, existing wearing plate 3 are steel plate because making material, and also the easy hitch 1 hook body to being in contact with it causes abrasion, in order to prevent the abrasion of hitch 1, the hitch 1 contacted with draught gear supporting seat 2 bearing surface is also provided with wearing plate; The maintenance of c, existing wearing plate, dismounting complexity, first need coupler and draft gear to decompose, excise, then plane on draught gear supporting seat bearing surface 5 polished flat on wearing plate 3 self-supporting face 5, be again welded with wearing plate 3 when changing wearing plate 3.
Summary of the invention
The object of the invention is to, for above-mentioned existing draught gear supporting seat problem, propose a kind of draught gear supporting seat, wear-resisting to realize, wearing plate assembly and disassembly advantage easily.
For achieving the above object, the technical solution used in the present invention is: a kind of draught gear supporting seat, comprise wearing plate, bearing and be fixed on for supporting the bearing surface of hitch on bearing, described bearing surface edge protrudes from bearing, and described bearing surface edge is provided with groove near the side of bearing; Described wearing plate is grooved wearing plate, and described grooved wearing plate sidewall is bent to form the projection with groove fit to the inside, and described wearing plate is fixed on the support surface with coordinating of groove by protruding, and described wearing plate adopts elastic fiber material to make.
Further, described groove is two or more.
Further, described elastic fiber material is nylon.
Further, described wear plate thickness is 8-14cm.
Further, the edge that described wearing plate deviates from bearing surface side is provided with chamfering.
Another object of the present invention also discloses a kind of coupler and draft gear, has the advantage of long service life, is applicable to 70 tonnes of railway trucks.
For achieving the above object, the technical solution used in the present invention is: a kind of coupler and draft gear, comprises above-mentioned draught gear supporting seat, and described draught gear supporting seat is arranged on below hitch, for supporting hitch.
Draught gear supporting seat of the present invention is simple and reasonable for structure, has the following advantages compared with existing draught gear supporting seat:
1, wear resisting property is good, and the wearing plate of this draught gear supporting seat adopts elastic fiber material to make, and improves wear resisting property, extends draught gear supporting seat service life;
2, adopt the wearing plate prepared of elastic fiber material, reduce its abrasion to hitch, draw gear wearing plate with it can be cancelled;
3, the wearing plate of draught gear supporting seat is fixed on the support surface with coordinating of groove by protruding, and be connected with bearing surface closely, assembly and disassembly are convenient.
