[0005] The disadvantage of a close analogue is its lack of reliability due to the possibility of warping and deformation of the wall and roof cladding.

[0007] The technical result achieved by the utility model is an increase in the reliability of a freight car.

[0038] A freight car comprises a frame 1, a body with a roof 5, end 8 and side 7 walls, a chassis 2, automatic coupling devices 3, braking equipment 4, the roof 5 and side walls 7 are connected via an upper frame 6, the roof 5 comprises a skin 5.1 and transverse arches 5.2. The roof skin 5.1 is made of corrugated sheets. The transverse arches 5.2 are fixed to the upper frame 6 and the skin 5.1. The skin 5.1 and the transverse arches 5.2 of the roof are connected to each other via brackets 9 containing shelves 9.1 and walls 9.2. The width of the shelf 9.1 of the bracket is less than the width of the corrugation 5.3 of the corrugated sheet of the skin. The shelves 9.1 of the brackets are installed in the corrugations 5.3 of the roof sheathing 5.1, and the walls 9.2 of the brackets 9 are connected to the transverse arches 5.2 of the roof.

[0039] The shelf length of 9.1 bracket can be 30÷100mm.

[0040] Bracket 9 can be made in the form of a bent sheet.

[0041] Bracket 9 can be made in the form of a corner.

[0042] Shelf 9.1 of bracket 9 can be made rectangular.

[0043] Bracket 9 in the development may have a mushroom shape.

[0044] The transitions from shelf 9.1 to wall 9.2 of bracket 9 can be made radial.

[0045] The thickness of the shelf 9.1 of the bracket 9 may not be less than the thickness of the sheathing 5.1.

[0046] The wall thickness 9.2 of bracket 9 may not be greater than the wall thickness of transverse arch 5.2 of roof 5.

[0047] The shelves 9.1 of the brackets 9 with the corrugation 5.3 of the roof sheathing, as well as the walls 9.2 of the brackets with the transverse arches 5.2 of the roof can be connected by welding, while the length of the welded seams connecting the shelf 9.1 with the corrugation 5.3 of the sheathing and the length of the welded seams connecting the wall 9.2 with the transverse arch 5.2 can differ by no more than 30%.

[0048] Unlike its counterpart, in which the skin and pillars are directly welded together without intermediate elements, in the proposed utility model, the skin and roof transverse arches are connected via brackets containing shelves and webs. The width of the bracket shelf is smaller than the width of the corrugation of the corrugated skin sheet. The bracket shelves are installed in the roof skin corrugations, and the webs of the brackets are connected to the roof transverse arches. The bracket contains a shelf and a web, allowing the shelf to be installed in the side wall skin corrugation, and the web of the bracket to be connected to the roof transverse arch. Installing the bracket in the corrugation prevents the skin from deforming, as the shelf supports the upper section of the corrugation and serves as a stiffening rib. Taken together, this design increases rigidity, eliminates the possibility of warping and deformation of the roof skin, and thus improves the reliability of the freight car.

[0049] In this particular case, the length of shelf 9.1 of bracket 9 can be 30–100 mm. A length of less than 30 mm may result in insufficient rigidity, while a length of more than 100 mm will increase the weight of the carriage, leading to operational inefficiencies.

[0050] In special cases, bracket 9 can be made in the form of a bent sheet, in the form of a corner, shelf 9.1 of bracket 9 can be made rectangular, bracket 9 in the development can have a mushroom shape, while in all these special cases, a technical result can be obtained, since these designs allow you to install the bracket in the corrugation of the sheathing, rigidly (for example, by welding) connect the sheathing and the arch of the roof through the bracket, increase rigidity and eliminate the likelihood of deformation of the sheathing.

[0051] In special cases, the thickness of shelf 9.1 of bracket 9 may be no less than the thickness of the skin 5.1. Calculations have shown that this design allows for additional enhancement of the bracket fastening reliability and, consequently, further enhancement of the freight car's reliability.

[0052] In special cases, the wall thickness 9.2 of bracket 9 may not exceed the wall thickness of transverse arch 5.2. Calculations have shown that this design further reduces the likelihood of roof deformation and, therefore, further increases the reliability of the freight car.

[0053] In special cases, the shelves 9.1 of the brackets with the corrugation 5.3 of the side wall sheathing, as well as the walls 9.2 of the brackets with the transverse arcs 5.2 can be connected by welding, while the length of the welded seams connecting the shelf 9.1 with the corrugation 5.3 of the sheathing and the length of the welded seams connecting the wall 9.2 with the transverse arc 5.2 may differ by no more than 30%. Calculations have shown that this design can further reduce the likelihood of roof deformation and, therefore, further increase the reliability of the freight car.

[0054] A freight car was manufactured in which the skin and roof transverse arches were connected to each other via brackets containing shelves and webs. The width of the bracket shelf was smaller than the width of the corrugated skin sheet corrugation. The bracket shelves were installed in the roof skin corrugations, and the webs of the brackets were connected to the roof transverse arches. The length of each bracket shelf was 50 mm. The bracket was made in the form of a corner from a bent sheet, made with a radius bending. The bracket shelf was rectangular. Each bracket in the developed pattern had a mushroom-shaped form. The transitions from the shelf to the web of each bracket were made with a radius. The thickness of the shelf of each bracket was not less than the thickness of the skin. The thickness of the web of each bracket was not greater than the thickness of the web of the roof transverse arch.The bracket shelves with the roof sheathing corrugation, as well as the bracket walls with the roof transverse arches, were welded together. The weld lengths between the shelf and the sheathing corrugation and the weld lengths between the wall and the transverse arch differed by no more than 10%. Testing and operational trials confirmed that sheathing deformation was eliminated.

[0055] Therefore, the claimed utility model allows for the technical result to be achieved, which consists in increasing the reliability of a freight car.
