The invention relates to a traction sleeper for a tank car, which comprises a traction beam, cover plates at the lower side of a sleeper beam and a lower middle cover plate of the sleeper beam, wherein the cover plates at the lower side of the sleeper beam and the lower middle cover plate of the sleeper beam are arranged below the traction beam; the cover plates at the lower side of the sleeper beam are arranged at both sides of the lower middle cover plate of the sleeper beam; the lower middle cover plate of the sleeper beam is arranged into a flat-plate structure; and according to the traction sleeper for the tank car, which is disclosed by the invention, a local clearance between a lower wing surface of Z-shaped steel at one side of the traction beam and the lower middle cover plate of the sleeper beam is eliminated, the reliability of the fatigue strength of the structure is enhanced, bending residual stress existing in an original structure is eliminated, the reliability of the fatigue strength of the structure is enhanced, the problem of strong assembly of the original structure, which exists when the lower middle cover plate of the sleeper beam is welded and the cover plates at the lower side of the sleeper beam are in grouped welding, is solved, and the strength reserve of the lower middle cover plate of the sleeper beam is enhanced.
Description
technical field [0001] The invention relates to a railway tank car pulling pillow. Background technique [0002] At present, the existing tens of thousands of railway tank cars in our country have adopted the lower middle cover structure of the corbel beam, such as figure 1 and figure 2 As shown, it is located between the traction beam and the upper center plate, which are welded by two B-shaped steels. There is a bending area in the structure, and it is lap welded to the bottom surface of the lower side cover plate of the corbel. [0003] Due to the excitation of track irregularities, the railway tank car is subjected to complex dynamic loads, and the structure of the tank car pull pillow is subjected to complex dynamic stress. Since the structure of the lower middle cover plate of the bolster is located between the traction beam and the upper center plate welded by two B-shaped steels, taking the tank car body ups and downs as an example, the vertical vibration of the b...
