Description

The utility model relates to the field of railway technology, namely to isothermal cars, in particular to refrigerated cars.

It is not known from the prior art to close the empty space formed in the frame area at the connection between the outer skin of the cargo compartment and the engine room skin in the bodies of isothermal cars.

(date of last access to Internet links: 11/14/2023). In these cars, at the junction of the cargo compartment skin and the engine room skin on each side of the body, there is an intermediate side wall post, the vertical sheet of which reaches only the upper level of the car frame.

The disadvantage of such car bodies is that the location of the intermediate sheet of the side wall of the body to the upper level of the car frame is not rigid enough for the body, which reduces the reliability of the car during operation.

This type of car was chosen as the closest analogue.

The technical problem solved by the proposed utility model is insufficient body rigidity.

The technical result achieved by the utility model is an increase in structural rigidity and, accordingly, an increase in the reliability of the proposed car.

The technical result is achieved due to the fact that the refrigerator car contains a body with a frame, a chassis, automatic coupling devices, brake equipment, doors, at the end part of the body there is an engine room in which refrigeration and heating equipment is installed, the body contains a frame mounted on the frame, intermediate and end posts, sheets of inner and outer skin and insulation between these sheets, while the intermediate sheet of the side wall of the body is connected to the outer skin of the cargo compartment and the skin of the engine room; according to the utility model, the intermediate sheet of the side wall of the body has a bend located at the level of the frame wall and rigidly connected to it, while the empty space formed between the intermediate sheet of the side wall of the body and the frame is closed by an insert rigidly connected to the frame and the intermediate sheet of the body, thereby forming a closed box-shaped structure.

The insert can be made in the form of a U-shaped profile.

The insert can be a power element.

The bend of the intermediate sheet of the side wall of the body can be connected to the frame wall by welding.

The insert can be connected to the frame wall by welding.

The inventive refrigerator car contains a body 1 with a frame 2, a chassis 3, automatic coupling devices 4, braking equipment 5, doors 6. At the end of the body 1 there is an engine room 7, in which refrigeration and heating equipment is installed. Body 1 contains a frame (side and end walls) mounted on frame 2, intermediate (not designated by position) and end posts 8, sheets of inner (not shown) and outer skin 9 and insulation between these sheets. Each intermediate sheet 10 of the side wall of the body 1 in its lower part has a bend 10.1 in the form of a shelf, which is located at the level of the wall 2.1 of the frame 2 and is rigidly connected to this wall 2.1. frames 2. Intermediate sheets 10 are located on both sides of the car. The intermediate sheets 10 are connected to the outer skin 9 of the cargo compartment 11 and the skin 14 of the engine room 7. An empty space 12 is formed between the top flange of the frame 2 and the bend 10.1 of the intermediate sheet 10. The distance L from the top flange of the frame 2 to the bend 10.1 of the intermediate sheet 10 is 40- 180 mm. In this case, this space 12 is closed by insert 13 (plug). Insert 13 is a power element, rigidly connected to frame 2 and intermediate sheet 10, forming a closed box-shaped structure. Insert 13 may have a U-shaped profile.

Insert 13 allows you to completely cover the empty space 12, while having an extremely minimal effect on the increase in metal consumption and allows you to increase the rigidity of the connection between the intermediate sheet 10 and frame 2.

In the stated technical solution, in comparison with a close analogue, the difference between the width of the frame and the body is due to the need to increase load capacity and reduce metal consumption.

An experimental refrigerated car was manufactured in which the intermediate sheets 10 are connected by their sides to the outer skin 9 and the skin 13 of the engine room 7, while an empty space 12 is formed between the upper flange of the frame 2 and the lower flange 10.1 of the intermediate sheet 10, which is closed by a U-shaped box 13. Calculations have shown that, in comparison with the case if the intermediate sheets are placed to the level of the top flange of the frame, then such a connection does not have sufficient rigidity indicators, as if the intermediate sheets were lowered from the level of the top flange of the frame below by a distance L of at least 40 mm , but no more than 180 mm, so as not to go beyond the bottom flange of the frame. This distance L optimally satisfies the provision of a more rigid connection of the car body. Above 180 mm, the intermediate sheet may extend beyond the bottom flange of the side frame, which will negatively affect the rigidity of the structure. It is not advisable to use distances L less than 40 mm, since the smaller the distance the intermediate sheet is placed on the side wall of the frame, the greater the chance of obtaining an unreliable structure in terms of the rigidity of the body frame.

Consequently, the claimed utility model makes it possible to provide a technical result consisting in increasing the rigidity of the structure and, accordingly, increasing the reliability of the claimed car.
