Description

Technical Field

[0001] The utility model belongs to the vehicle towing connection technology, and mainly relates to a trailer wear-resistant plate which is convenient for lubricating a towing pin. Background Art

[0002] Traditional trailer wear plates are made of ordinary steel plates and are installed between the lower part of the trailer traction disc and the upper part of the traction locomotive mounting seat in an extrusion support contact state. Due to the flat plate structure design, it is impossible to reliably and effectively inject lubricating oil, and there is no oil film. During the operation of the vehicle, especially during the turning process, a huge friction torque is generated, which not only wastes the traction power of the traction locomotive, but also causes serious wear of the trailer wear plate, short service life, and cumbersome replacement operation. In order to solve the above problems, with the improvement of scientific and technological level, new wear-resistant materials have been successfully developed. Therefore, trailer wear plates made of wear-resistant materials have begun to be produced and used, which has preliminarily solved the technical problems existing in traditional technologies. However, since the plate has no change in structural design, only the friction problem between the trailer traction disc and the traction locomotive mounting seat and the trailer wear plate is solved by using wear-resistant materials. However, the lubrication problem of the traction pin on the trailer and the traction pin axial locking mechanism on the traction locomotive has not been solved. Lubrication is impossible, and there is still dry friction between the traction pin and the traction pin axial locking mechanism on the traction vehicle, which has a short service life and is difficult to maintain. Summary of the invention

[0003] The purpose of the utility model is to address the problems existing in the above-mentioned prior art, combine with the actual needs of the current trailer and traction locomotive traction connection, and develop and design a trailer wear-resistant plate that is convenient for lubrication of the traction pin, so as to achieve and complete the purpose of sufficient and good lubrication between the trailer traction pin and the traction vehicle traction pin axial locking mechanism.

[0004] The basic design of the utility model is: an annular groove is arranged on the upper end surface of the trailer wear-resistant plate, located at the outer side of the circumference of the traction pin through hole; a radial inner groove and a radial outer groove are respectively arranged on the upper end surface of the trailer wear-resistant plate, located at the inner and outer sides of the annular groove; a vertical groove is opened on the inner wall surface of the circumference of the traction pin through hole of the trailer wear-resistant plate; the inner end and the outer end of the radial inner groove are respectively connected with the vertical groove and the annular groove; the inner end of the radial outer groove is connected with the annular groove; the outer end of the radial outer groove is open, thereby forming a trailer wear-resistant plate that is convenient for lubrication of the traction pin.

[0005] The utility model solves the lubrication problem of dry friction between the trailer traction pin and the traction pin axial locking mechanism of the traction vehicle by sequentially arranging mutually connected radial outer grooves, annular grooves, radial inner grooves and vertical grooves on the trailer wear-resistant plate, and injecting lubricating grease into the grooves when in use. The utility model has the characteristics of simple and reasonable structure, easy and convenient operation, good lubrication effect, extended service life of parts, reduced maintenance times and reduced use cost.

[0010] The following is a detailed description of the implementation scheme of the utility model in conjunction with the accompanying drawings. A trailer wear plate for facilitating the lubrication of a traction pin comprises a trailer wear plate 1, a traction pin through hole 1-1 is arranged at the central portion of the trailer wear plate 1, an annular groove 1-4 is arranged on the upper end surface of the trailer wear plate 1, located at the outer portion of the circumference of the traction pin through hole 1-1, a radial inner groove 1-3 and a radial outer groove 1-5 are arranged on the upper end surface of the trailer wear plate 1, located at the inner and outer portions of the annular groove 1-4, respectively, a vertical groove 1-2 is opened on the inner wall surface of the circumference of the traction pin through hole 1-1 of the trailer wear plate 1, the inner end and the outer end of the radial inner groove 1-3 are connected to the vertical groove 1-2 and the annular groove 1-4 respectively, the inner end of the radial outer groove 1-5 is connected to the annular groove 1-4, and the outer end of the radial outer groove 1-5 is open.

[0011] When in use, the trailer wear plate 1 is installed between the lower part of the trailer traction disc and the upper part of the traction locomotive mounting seat. After the traction pin on the trailer traction disc is inserted into the traction pin through hole 1-1 of the trailer wear plate 1, its lower end is axially locked with the traction pin axial locking mechanism of the traction vehicle. Lubricating grease is injected from the outer end opening of the radial outer groove 1-5 using an oil gun. The lubricating oil is injected into the traction pin on the trailer traction disc and the traction pin axial locking mechanism on the traction vehicle through the radial outer groove 1-5, the annular groove 1-4, the radial inner groove 1-3, and the vertical groove 1-2 in sequence, forming a lubricating oil film, which undertakes and completes the lubrication operation.
