Abstract

FIELD: machine building.

SUBSTANCE: invention relates to railway transport, in particular to friction wedges of freight cars and to methods of their marking. Friction wedge comprises hollow body with holes in sidewalls, inner rib and on thrust platform. Drain hole on support platform is divided by inner rib into two parts. Seal clamp is secured around the inner rib of the wedge in the drain hole. Surface of seal with marked marking is arranged inside wedge case.

Description

The invention relates to railway transport, in particular, to the design of a vibration damper of a freight wagon trolley and a method for its identification.

Standards governing the technical requirements for wedges of friction trolleys of freight cars require the use of markings for subsequent identification of the wedge during operation. The friction wedge is to be marked by casting in the manufacture by casting or by striking. Marking is applied to the surface not subject to wear during operation. However, these methods do not guarantee protection against the use of counterfeit products.

Known friction wedge made in the form of a hollow wedge-shaped body with a supporting platform and a protrusion, side walls, rear wall, upper and front walls, conjugated by an inclined wall having working surfaces separated by a recess, the inner ribs. Moreover, the side walls and the inner rib are made with through holes, and on the outer surface of the support platform there is an annular groove for installing the spring, the rear wall has an annular groove identical to the annular groove of the support platform, and a protrusion (according to patent RU186214, IPC B61F 5/12, publ. 11.01.19).

The closest technical solution is a friction wedge containing a housing with a supporting platform, front horizontal and inner ribs, an annular collar, horizontal and vertical walls, paired with an inclined wall having a working part, which includes a working one solid or two working separated by a recess from each other working convex surfaces. Moreover, the working part of the wedge is made integral with the wedge body and is a part in the form of a solid casting from a metal alloy (according to patent RU135300, IPC B61F 5/12, publ. 10.12.13).

The disadvantage of these wedges is that they can only be marked with the standard methods described above.

The technical result achieved by using the present invention is to simplify the method of identifying a friction wedge through the use of a plastic seal-clamp and design features of the wedge.

The specified technical result is achieved by the fact that a method for identifying a friction wedge is used, consisting of a hollow wedge housing with a support platform and a protrusion, side walls, a rear wall, an upper and a front wall, conjugated by an inclined wall having working surfaces separated by a recess, and an inner rib, moreover, the side walls and the inner rib are made with through holes, and an annular bead is made on the outer surface of the supporting platform, and differs in that inside the hollow housing aetsya plastic seal in the form of a clamp, comprising the marking which is fixed in the outflow opening of the support platform formed within the annular rib and the inner rib divided into two parts, the seal is located around the inner edge.

The proposed method is implemented using a friction wedge, which consists of a hollow wedge housing with a support platform and a protrusion, side walls, a rear wall, an upper and a front wall, conjugated by an inclined wall having working surfaces separated by a recess, and an inner rib, and the side walls and the inner rib is made with through holes, and an annular bead is made on the outer surface of the supporting platform and differs in that a drain opening is made in the supporting area inside the annular bead s divided by an inner edge, a through-hole in the inner edge has an area equal to at least 0.5 square inner edge and through holes in the side walls have an equal area of not less than 0.5 square through-hole in the inner edge.

The invention is illustrated by the following drawings:

FIG. 1 - friction wedge, side view;

FIG. 2 - friction wedge, top view;

FIG. 3 - friction wedge, longitudinal section;

FIG. 4 - friction wedge, bottom view;

FIG. 5 - friction wedge with seal;

FIG. 6 - friction wedge with seal, cut;

FIG. 7 - seal.

The friction wedge (Fig. 1) consists of a hollow wedge housing 1 with a support platform 2 and a protrusion 3, side walls 4, rear wall 5, upper wall 6 and front wall 7, conjugated by an inclined wall 8 having working surfaces 9 separated by a recess 10 , and the inner rib 11 (Fig. 2). The side walls 4 and the inner rib 11 are made with through holes 12 and 13, respectively. An annular bead 14 is made on the outer surface of the support pad 2 (Fig. 4).

In the reference area 2 inside the annular flange 14, a drain hole 15 is made, divided by an inner rib 11.

Inside the hollow body 1 is a plastic seal 16 (Fig. 5, 6) containing a marking, which is mounted in the drain hole 15 around the inner rib 11.

The through hole 13 in the inner rib 11 has an area equal to at least 0.5 of the area of the inner rib 11. The through holes 12 in the side walls 4 have an area equal to at least 0.5 of the area of the through hole 13 in the inner rib 11.

The seal 16 (Fig. 7) is a disposable clamp, which after installation cannot be removed without damage.

Application.

The seal 16 is installed inside the hollow body 1. With this arrangement, the seal does not interfere with the operation of the product during operation and does not mate with rubbing surfaces, which allows it to retain identification data throughout the entire life cycle of the product. This anchorage is also anti-vandal and protected from external influences, which increases its durability and the safety of identification information.

Enlarged through holes 12 in the side walls 4 provide a convenient installation of the seal 16.

With this fixing method, it is possible to use various types of seal clamps.

Thus, the application of the method for identifying a friction wedge with a seal in the form of a clamp, provided that the design of the wedge according to the invention is used, helps to achieve a technical result, which consists in simplifying the method for identifying a friction wedge.
