The invention concerns the structural elements of the body of isothermal transport vehicle, in particular, the isothermal freight railroad car. A body of isothermal transport vehicle includes a frame, lateral and end walls, a roof and a floor of multilayer structure. In accordance with the invention, the floor includes a bottom, a through centre sill with heat-insulating backings fastened thereon, side beams, stringers with fixed metallic strips and heat-insulating backings, frontal sheets, body bolster beams, cross beams with stiffeners welded to them, an upper coating and an insulation in the spaces between the elements of frame, bottom and upper coating. In the case between the upper coating and insulating material an insulating cardboard is located, and the upper coating itself is metallic and is fastened on the elements of frame. The invention provides for increase of working volume of the body within the limits of set overall size of rolling stock, increase of the service life of the isothermal transport vehicle, lowering of its centre of weight and increase of the stability during motion. |
