Description

The utility model relates to the field of railway transport, in particular to coupling devices of railway transport, namely to articulated joints of freight cars.

Known from the prior art is a hinged joint for freight cars (RU 2778087 C1, B61G 5/02, publ. 08/15/2022), containing a fifth part with an upper flange and a lower support platform and a driving part with a mounting hole, hingedly connected to each other using a central the finger, installed with its lower end in the hole of the lower support platform of the fifth part, is connected at its upper end to the upper flange of the fifth part, and secured by a fixing element in the form of an overhead holder of the central finger with supporting ends and a hole.

The technical problem is the high metal consumption of the articulated joint of a freight car, namely the high metal consumption and weight of the overhead holder.

The technical result of the utility model is to reduce the metal consumption and weight of the overhead holder of the articulated unit for the articulation of a freight car, while maintaining the necessary strength characteristics of the articulation device for freight cars.

The specified technical result is achieved by a hinged unit for the articulation of freight cars, including a fifth part and a driving part, hingedly connected to each other using a central pin secured by an overhead holder containing support ends and a platform with a hole in which recesses with a depth of B are made in the supporting ends of the overhead holder 5 mm to 85 mm, with the distance N from the outer contour of the overlay holder to the outer contour of the recess ranging from 20 mm to 35 mm.

In embodiments of the utility model, it is preferable to make the depth B of the recess in the support ends of the overhead holder from 5 mm to 25 mm; the recesses in the supporting ends of the overhead holder can be made of variable width with an increase in the direction of the platform with the hole from the smallest width S _min of at least 10 mm to the largest width S _max of no more than 300 mm.

The utility model differs from the prototype in that the supporting ends of the overhead holder have recesses with a depth B from 5 mm to 85 mm, while the distance N from the outer contour of the overhead holder to the outer contour of the recess ranges from 20 mm to 35 mm; it is preferable to make the depth B of the recess in the support ends of the overhead holder from 5 mm to 25 mm; the recesses in the supporting ends of the overhead holder can be made of variable width with an increase in the direction of the platform with the hole from the smallest width Smin of at least 10 mm to the largest width _Smax of not more than 300 mm.

Such differences from the prototype give grounds to assert that the proposed technical solution meets the patentability criterion for a utility model - “novelty”.

The claimed technical solution is illustrated by graphic images, where

in fig. 1 shows a hinged joint for freight cars, isometric view;

in fig. 2 - overhead holder, isometric view;

in fig. 3 - overhead holder, top view;

in fig. 4 - overhead holder, side view.

The articulated unit for the articulation of freight cars includes a base part 1 with side walls 1.1 and a drive part 2, hingedly connected to each other using a central pin 3, and an overhead holder 4 with support ends 4.1 and a platform 4.2 with a hole.

The technical result, which consists in reducing the metal consumption and weight of the overhead holder of the articulated unit for the articulation of a freight car, while maintaining the necessary strength characteristics of the articulation device for freight cars, is ensured as follows.

The support ends 4.1 of the overhead holder 4 have recesses 4.3 with a depth B of 5 mm to 85 mm, while the distance N from the outer contour 4.1.1 of the overhead holder to the outer contour of the recess 4.3.1 ranges from 20 mm to 35 mm. The proposed implementation makes it possible to reduce the weight of the overhead holder 4 by making recesses 4.3 with a geometry corresponding to the nature of the stresses.

Going beyond the lower limits of the ranges does not provide an optimal reduction in weight and metal consumption of the overhead holder for the articulated joint of a freight car. Going beyond the upper limits of the ranges is not advisable, because sufficient strength of the overhead holder 4 will not be ensured and will require the fastening of additional reinforcing elements, which will lead to an increase in the mass and metal consumption of the articulated joint of the freight car.

A specific example of the implementation of a utility model is a hinged joint for freight cars, including a fifth wheel part 1 containing side walls 1.1 with landing recesses (position not shown), in which the support ends 4.1 of the overhead holder 4 are placed for fixing the central pin 3, which pivotally connects the fifth wheel part 1 and the driving part 2. The overhead holder 4 is a cast part, in the supporting ends 4.1 of which there are recesses 4.3 with a depth B, preferably from 5 mm to 25 mm, and a variable width with an increase in the direction of the platform with a hole from the smallest width Smin not less 10 mm to the greatest width S _max not more than 300 mm in areas with the lowest stress concentration. This design is preferable to achieve the technical result - reducing the metal consumption and weight of the overhead holder of the articulated unit for the articulation of a freight car, while maintaining the necessary strength characteristics of the articulation device for freight cars.
