FIELD: railway transport. ^ SUBSTANCE: proposed blind-bottom open-top car running parts, frame with body. Cantilever parts of center sill 17 are made up to level of bolsters 3 to which automatic couplers 5 transmit load. Tops of first pair of V-shaped struts 18 start in places of connection of cantilever parts of center sill 17 with lower binding of end face walls, and bases of struts are arranged in places of connection of bolsters with binding of frame. Tops of second pair of V-shaped struts 19 are arranged at reverse side of bolsters and they rest of central parts of central sills, and their bases rest on places of connection of cross beams with frame binding, thus protecting bolsters from loads which cause side bending. Lower thickened sheets of sides play the part of frame binding closed and end faces by lower binding of end face wall. ^ EFFECT: increased capacity of body and reduced weight of body. ^ 3 cl, 4 dwg |
