[0044] The insulated car comprises a frame 1, a body with end 11 and side 10 walls, a roof 13 and a floor (not designated by position), 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, an internal 10.4 and an external 10.1 skin, wherein the external skin 10.1 is made of corrugated sheets, and the vertical posts 10.2 are secured to the side beams 9 and the external skin 10.1. The outer sheathing 10.1 and the vertical posts 10.2 of the side wall 10 are connected to each other through 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 outer sheathing 10.1 of the side wall 10, and the walls 12.2 of the brackets 12 are connected to the vertical posts 10.2 of the side wall 10.

[0045] The length of shelf 12.1 of bracket 12 can be 30÷100 mm.

[0046] Bracket 12 can be made in the form of a bent sheet.

[0047] Bracket 12 can be made in the form of a corner.

[0048] Shelf 12.1 of bracket 12 can be made rectangular.

[0049] Bracket 12 in the development may have a mushroom shape.

[0050] The transitions from shelf 12.1 to wall 12.2 of bracket 12 can be made radial.

[0051] The thickness of the shelf 12.1 of the bracket 12 may not be less than the thickness of the outer cladding 10.1.

[0052] 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.

[0053] Shelves 12.1 of brackets with corrugation 10.3 of the outer cladding of the side wall, 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 of the connection of shelf 12.1 with corrugation 10.3 of the cladding and the length of the welded seams of the connection of wall 12.2 with post 10.2 can differ by no more than 30%.

[0054] Unlike its counterpart, in which the exterior cladding and vertical posts are directly welded together without intermediate elements, in the proposed utility model, the exterior cladding and vertical posts 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 corrugation of the corrugated cladding sheet. The bracket shelves are installed in the corrugations of the exterior cladding of the side wall, and the webs of the brackets are connected to the vertical posts of the side wall. The bracket contains a shelf and a web, allowing the shelf to be installed in the corrugation of the exterior cladding of the side wall, and the web of the bracket to be connected to the vertical post of the side wall. Installing the bracket in the corrugation prevents the cladding from deforming, as the shelf supports the upper section of the corrugation and serves as a stiffener.Taken together, this design allows for increased rigidity, eliminates the possibility of warping and deformation of the wall cladding, and thus increases the reliability of the isothermal car.

[0055] 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.

[0056] 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.

[0057] In special cases, the thickness of shelf 12.1 of bracket 12 may be no less than the thickness of the outer skin 10.1. Calculations have shown that this design allows for additional enhancement of the bracket fastening reliability and, consequently, further enhancement of the insulated car's reliability.

[0058] In special cases, the thickness of the wall 12.2 of the 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, consequently, an additional increase in the reliability of the isothermal car.

[0059] In special cases, the shelves 12.1 of the brackets with the corrugation 10.3 of the outer skin of the side wall, 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 skin 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 can further reduce the likelihood of wall deformation and, therefore, further increase the reliability of the isothermal car.

[0060] An insulated railcar was manufactured in which the outer skin and vertical side wall struts were rigidly connected to each other via brackets containing shelves and webs. The width of each bracket shelf was less than the width of the corrugated skin sheet corrugation. The bracket shelves were installed in the corrugations of the outer skin of the side wall, and the webs of the brackets were connected to the vertical side wall struts. 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 side wall strut.The bracket shelves with the corrugated outer skin of the side wall, as well as the bracket webs with the vertical side wall posts, were welded together. The weld lengths between the shelf and the corrugated skin and the web and post welds differed by no more than 10%. Testing and operational trials confirmed that the skin deformation was eliminated.

[0061] Therefore, the claimed utility model allows for the technical result to be achieved, which consists in increasing the reliability of an insulated wagon.
