Abstract

The utility model relates to a coal flatcar, pertaining to a railway transporting vehicle, in particular to a railway freight flatcar. The coat flatcar is composed of an under-frame, side walls and side walls. The under-frame is composed of body bolsters, crossbeams, longitudinal beams, side sills and draught sills. The side sills and the side sills are respectively arranged at both sides and sides of the under-frame, forming a flatcar. The key technology is that a cupped concave bottom is positioned at the center of the under-frame. The utility model is characterized in that: 1, the flatcar capacity can be increased, the height of centre of gravity is lowered, more importantly a force framework is formed with the side walls and the draught sills by the cupped concave bottom to fully utilize the bearing capacities of various locations with a similar or identical rigidity or minimum stress gradient, obtaining a optimal transporting effect. 2, the high-intensity plate and roll forming light-duty steel are used, lowing the weight of the steel structure of the flatcar body under the premise that the rigidity is not lowered, enabling a greater bearing capacity of the structure and enhancing the curve negotiating capability and improving the driving quality of the flatcar.
