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

[0008] The technical result is achieved due to the fact that a freight car, comprising a body with a frame, end and side walls, a chassis, automatic coupling devices, braking equipment, the frame includes end beams, a center beam, kingpin beams, cross beams, the side wall contains sheathing and posts, wherein the sheathing is made of corrugated sheets, and the vertical posts are fixed to the side beams and sheathing, according to the utility model, the sheathing and posts of the side wall are connected to each other through brackets containing shelves and walls, wherein the width of the bracket shelf is less than the width of the corrugation of the corrugated sheet of the sheathing, the shelves of the brackets are installed in the corrugations of the sheathing of the side wall, and the walls of the brackets are connected to the vertical posts of the side wall.

[0040] 12.1 - bracket shelf,

[0041] 12.2 - bracket wall.

[0042] The freight car comprises a frame 1, a body with end 11 and side 10 walls, a chassis 2, automatic coupling devices 3, and braking equipment 4. The frame 1 includes a center beam 6, end 5, kingpin 7, cross 8, and side 9 beams. The side wall 10 comprises vertical posts 10.2 and a skin 10.1. The skin 10.1 is made of corrugated sheets. The vertical posts 10.2 are secured to the side beams 9 and the skin 10.1. The sheathing 10.1 and the vertical posts 10.2 of the side wall 10 are connected to each other via brackets 12 containing shelves 12.1 and walls 12.2, wherein the width of the shelf 12.1 of the bracket is less than the width of the corrugation of the corrugated sheet of the sheathing. The shelves 12.1 of the brackets 12 are installed in the corrugations 10.3 of the sheathing 10.1 of the side wall 10. The walls 12.2 of the brackets 12 are connected to the vertical posts 10.2 of the side wall 10.

[0043] The length of shelf 12.1 of bracket 12 can be 30÷100 mm.

[0044] Bracket 12 can be made in the form of a bent sheet.

[0045] Bracket 12 can be made in the form of a corner.

[0046] Shelf 12.1 of bracket 12 can be made rectangular.

[0047] Bracket 12 in the development may have a mushroom shape.

[0048] The transitions from shelf 12.1 to wall 12.2 of bracket 12 can be made radial.

[0049] The thickness of the shelf 12.1 of the bracket 12 may not be less than the thickness of the sheathing 10.1.

[0050] The wall thickness 12.2 of bracket 12 may not be greater than the wall thickness of vertical post 10.2 of side wall 10.

[0051] Shelves 12.1 of brackets with corrugation 10.3 of the side wall sheathing, as well as walls 12.2 of brackets with vertical posts 10.2 of the side wall can be connected by welding, while the length of the welded seams connecting shelf 12.1 with corrugation 10.3 of the sheathing and the length of the welded seams connecting wall 12.2 with post 10.2 can differ by no more than 30%.

[0052] Unlike its counterpart, in which the skin and vertical supports are directly welded together without intermediate elements, in the proposed utility model, the skin and vertical supports of the side wall are connected via brackets containing shelves and webs. The width of the bracket shelf is smaller than the width of the corrugated skin sheet. The bracket shelves are installed in the side wall skin corrugations, and the webs of the brackets are connected to the vertical supports of the side wall. The bracket comprises 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 vertical support of the side wall. 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 wall skin, and thus improves the reliability of the freight car.

[0053] In this particular case, the length of shelf 12.1 of bracket 12 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.

[0054] In special cases, bracket 12 can be made in the form of a bent sheet, in the form of a corner, shelf 12.1 of bracket 12 can be made rectangular, bracket 12 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 rack through the bracket, increase rigidity and eliminate the likelihood of deformation of the sheathing.

[0055] In special cases, the thickness of shelf 12.1 of bracket 12 may be no less than the thickness of the skin 10.1. 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.

[0056] In special cases, the thickness of wall 12.2 of bracket 12 may not be greater than the thickness of the wall of the vertical post 10.2 of the side wall 10. Calculations have shown that this design allows for an additional reduction in the likelihood of wall deformation and, therefore, an additional increase in the reliability of the freight car.

[0057] In special cases, the shelves 12.1 of the brackets with the corrugation 10.3 of the side wall sheathing, as well as the walls 12.2 of the brackets with the vertical posts 10.2 of the side wall can be connected by welding, while the length of the welded seams connecting the shelf 12.1 with the corrugation 10.3 of the sheathing and the length of the welded seams connecting the wall 12.2 with the post 10.2 may differ by no more than 30%. Calculations have shown that this design allows for an additional reduction in the likelihood of wall deformation and, consequently, an additional increase in the reliability of the freight car.

[0058] A freight car was manufactured in which the skin and vertical struts of the side wall were rigidly connected to each other through brackets containing shelves and webs. The width of each bracket shelf was less than the width of the corrugation of the corrugated skin sheet. The bracket shelves were installed in the corrugations of the side wall skin, and the webs of the brackets were connected to the vertical struts of the side wall. 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 vertical strut of the side wall.The bracket shelves were connected to the side wall corrugated sheathing, as well as the bracket webs to the side wall vertical posts, by welding. The length of the weld seams connecting the shelf to the corrugated sheathing and the length of the weld seams connecting the web to the post differed by no more than 10%. Testing and operational trials confirmed that the sheathing was free of deformation.

[0059] Therefore, the claimed utility model allows for the technical result of increasing the reliability of a freight car.
