Description

The utility model relates to railway transport and concerns the design of railway wagon bogies.

From the patent of the Russian Federation No. 2769028 for the invention, a wheelset of a three-axle bogie of a freight railway car is known, including an axle with wheels pressed onto it and bearing assemblies, balancers, each of which is a steel casting with asymmetrically made end parts and an arched opening closed in the middle part having support and thrust surfaces for the bearing assembly, while in each end part of the balancer there is an opening for accommodating the side frame of the bogie, limited by vertical walls with holes made in them for connecting the balancer with the side frames, while in the center of the lower part of the opening of each balancer is made a vertically oriented hole formed by means of inclined walls located opposite each other in the longitudinal and cross section of the balance bar, expanding the hole downwards.

From the patent of the Russian Federation No. 213129 for a utility model, a balance beam of a three-axle bogie of a freight railway car is known, which is a steel casting with asymmetrically made end parts closed in the middle part by a cylindrical opening for accommodating a bearing, while each end part of the balance beam has an opening for accommodating the side frame of the bogie , limited by vertical walls, with holes made in them for connecting the balancer to the side frames by means of rollers and a horizontal wall with a groove made in it for installing a wear-resistant element that serves as a support for the side frame of the bogie, while openings for installing the side frame are pressed into the holes of the vertical walls wear-resistant bushings; technological holes are made in the vertical walls of the balancer in their sections between the cylindrical opening for the bearing and the opening for the side frame.

The disadvantage of the known designs of balancers is their lack of strength and reliability.

The balancer according to patent No. 213129 is selected as the closest analogue.

The technical problem solved by the proposed utility model is the elimination of the shortcomings of analogues.

The technical result achieved by the utility model is to increase the strength and reliability of the balancer of a three-axle railway bogie.

The technical result is achieved due to the fact that in the balance beam of a three-axle railway bogie, which is a steel casting with asymmetrically made end parts, closed in the middle part by a cylindrical opening for accommodating the bearing, while in each end part of the balance beam there is an opening for accommodating the side frame of the bogie, limited vertical walls, with holes made in them for connecting the balancer with the side frames and the horizontal wall, on the vertical walls in their sections between the opening for placing the side frame of the bogie and the cylindrical opening, technological holes are made, according to the utility model, on the inner surfaces of the vertical walls in the areas between the technological holes and the surface limiting the cylindrical opening are stiffening ribs rigidly connecting the opposite vertical walls, each rib is also rigidly connected to the surface limiting the cylindrical opening.

The stiffening ribs can be located one above the other along the respective vertical walls.

The stiffening ribs can be connected to the vertical walls and the surface that bounds the cylindrical opening by welding.

The stiffeners can be made integral with the vertical walls and the surface that bounds the cylindrical opening.

The claimed utility model is illustrated by figures.

In FIG. 1 shows a general view of the proposed balancer.

In FIG. 2 shows the inventive balancer with a longitudinal vertical section of one end part.

In FIG. 3 shows a longitudinal horizontal section of the proposed balancer.

Positions on figures:

1 - end parts;

2 - cylindrical opening;

3 - opening for placement of the side frame;

4 - vertical walls;

5 - holes for connecting the balancer with the side frame;

6 - horizontal wall;

7 - technological holes;

8 - stiffeners.

The inventive balancer triaxial railway bogie is a steel casting with asymmetrically made end parts 1, closed in the middle part of the cylindrical opening 2 to accommodate the bearing; at the same time, in each end part 1 of the balancer there is an opening 3 for placing the side frame of the cart, limited by vertical walls 4, with holes 5 made in them for connecting the balancer with the side frames and the horizontal wall 6; technological holes 7 are made on the vertical walls 4 in their sections between the opening 3 for placing the side frame of the cart and the cylindrical opening 2. connecting opposite vertical walls 4; wherein each rib 8 is also rigidly connected to the surface bounding the cylindrical opening 2.

Stiffening ribs 8 are located one above the other along the corresponding vertical walls 4. Stiffening ribs 8 can be connected to the vertical walls 4 and the surface limiting the cylindrical opening 2 by welding or can be made integral with the vertical walls 4 and the surface limiting the cylindrical opening 2.

The vertical walls 4 in the area between the opening 3 for placing the side frame of the truck and the cylindrical opening 2 are weakened by technological holes 7. Therefore, the need to make technological holes 7 should not lead to weakening of the vertical walls 4 and, consequently, to weakening the balancer as a whole.

To strengthen the structure of the balancer, to strengthen the vertical walls 4, in the areas between the technological holes 7 and the surface limiting the cylindrical opening 2, stiffeners 8 are made to reinforce the vertical walls 4 in these areas.

Strengthening the vertical walls 4 increases the strength of the balance bar compared to the closest analogue (also made with process holes) and, accordingly, increases its reliability, by reducing, or even completely eliminating damage, deformation of the balance bar in the areas between the process holes 7 and the surface limiting cylindrical opening 2, during operation, i.e. in the process of impact on the balancer of dynamic loads.

The ribs 8 do not go inside the technological holes 8, therefore, they do not limit their functionality.

Thus, the claimed utility model fully ensures the achievement of the technical result, which consists in increasing the strength and reliability of the balancer of a three-axle railway bogie.
