Described draught gear supporting seat 2 comprises wearing plate 3, bearing 4 and is fixed on bearing for the bearing surface 5 that supports hitch 1, 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, prevents bearing surface 5 abrasion, when goods train vehicle moves, when hitch 1 is subject to longitudinal loading effect generation stretching and compression, hitch 1 and bearing surface 5 produce abrasion, when certain limit is arrived in bearing surface 5 abrasion, just need to change draught gear supporting seat 2, cause the waste of human and material resources.Welding wearing plate 3, can prevent the abrasion of draught gear supporting seat 2 bearing surfaces 5 on draught gear supporting seat 2 bearing surfaces 5, when draught gear supporting seat 2 wearing plate 3 abrasion are transfinited, needs in time to change wearing plate 3; B, play the effect of cushion block, can adjust by the wearing plate 3 of changing different-thickness the height of hitch 1, to guarantee that vehicle is to the requirement of hitch 1 height.
Existing draught gear supporting seat 2 exists following shortcoming: a, wearing plate 3 easy to wear, and existing wearing plate 3 adopts steel plates to make, and abrasion resistance is poor, and maintenance is changed frequent, has wasted a large amount of human and material resources; B, existing wearing plate 3 are steel plate because making material, also easily the hitch 1 hook body that is in contact with it are caused abrasion, in order to prevent the abrasion of hitch 1, and also are provided with wearing plate on hitch 1 that draught gear supporting seat 2 bearing surfaces contact; At first c, existing wearing plate maintenance, dismounting complexity need when changing wearing plate 3 coupler and draft gear is decomposed, and with excision on wearing plate 3 self-supporting faces 5, then plane on draught gear supporting seat bearing surface 5 are polished flat, and again add weldering 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, the wearing plate assembly and disassembly are 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 bearing the bearing surface that is used for supporting hitch, described bearing surface edge protrudes from bearing, and described bearing surface edge is provided with groove near a side of bearing; Described wearing plate is the 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 bearing surface by projection and groove, and described wearing plate adopts elastic fiber material to make.
Further, described groove is more than two.
Further, described elastic fiber material is nylon.
Further, described wearing plate thickness is 8-14cm.
Further, the described wearing plate edge that deviates from bearing surface one side is provided with chamfering.
Another object of the present invention also discloses a kind of coupler and draft gear, has advantages 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, comprise above-mentioned draught gear supporting seat, and described draught gear supporting seat is arranged on below hitch, is used for supporting hitch.
Draught gear supporting seat of the present invention is simple and reasonable for structure, and comparing with existing draught gear supporting seat has the following advantages:
1, wear resisting property is good, and the wearing plate of this draught gear supporting seat adopts elastic fiber material to make, and has improved wear resisting property, has extended draught gear supporting seat service life;
2, adopt the wearing plate of elastic fiber material preparation, reduced its abrasion to hitch, can cancel draw gear wearing plate with it;
3, the wearing plate of draught gear supporting seat by projection and being fixed on bearing surface of groove, is connected with bearing surface closely, and assembly and disassembly facilitate.
