Abstract
The utility model relates to a railway vehicle car body traction beam device which at least comprises a car coupler plate, an upper cover plate and a lower cover plate, wherein the car coupler plate is arranged between the upper cover plate and the lower cover plate and vertically fixed on the upper cover plate and the lower cover plate, and the upper cover plate is open on one end or two ends. Longitudinal force between the railway vehicle car body traction beam device and a floor section bar is transmitted by the upper cover plate, due to a special H-shape of the upper cover plate, the longitudinal force can be dispersed and stress concentration is avoided. The upper cover plate of the railway vehicle car body traction beam and the floor section bar are connected in welding mode or riveting mode, and therefore the floor section bar can achieve a through-length structure. The lower cover plate and a rib plate of the railway vehicle car body traction beam device are provided with overlap joints and convenient to assemble, and welding deformation can also be absorbed conveniently.
