Problems solved by technology
Scribing and cutting are required, and the straightness and roughness are difficult to guarantee; and due to the long spliced weld seam, welding deformation is prone to occur during assembly welding, so special tooling and fixtures are required to clamp during assembly welding, and further inspection is required after welding. Adjustment and repair; before and after installation, the 24 holes of Φ22 from the plate base are respectively drilled by a radial drilling machine, and there is a certain deviation in the size of the hole distance
The traction beam of this structure has low production efficiency and poor quality

The invention discloses an integral chassis towing beam of a railway carriage. A first upper airfoil and a second upper airfoil are successively arranged from a sleeper beam side to an end beam side above a main board. A first lower airfoil, a second lower airfoil, a third lower airfoil and a fourth lower airfoil are successively arranged from the sleeper beam side to the end beam side below the main board. The upper airfoils and the lower airfoils are outwards bent and are vertical to the main board. Notches are arranged between the first lower airfoil and the second lower airfoil, and between the second lower airfoil and the third lower airfoil, respectively. The adjacent end surfaces of the first upper airfoil and the second upper airfoil and the adjacent end surfaces of the third lower airfoil and the fourth lower airfoil are respectively welded and fixed. The notches between the first lower airfoil and the second lower airfoil, and between the second lower airfoil and the third lower airfoil are welded to be fixedly connected with each other respectively through a first additional board and a second additional board. The towing beam adopts the integral structure and is bent and shaped through the material all in one piece. Therefore, the quality of the towing beam is greatly improved.
Description
technical field [0001] The invention relates to a steel structure assembly tire for a railway vehicle underframe, and belongs to the technical field of railway vehicle underframe tooling. Background technique [0002] The traction beam is an important part of the bus chassis and is the main carrier of longitudinal and lateral loads, and its shape is relatively complicated. The traction beam of the chassis of ordinary railway passenger cars is formed by splicing 30a channel steel made of Q235B. Scribing and cutting are required, and the straightness and roughness are difficult to guarantee; and due to the long spliced weld seam, welding deformation is prone to occur during assembly welding, so special tooling and fixtures are required to clamp during assembly welding, and further inspection is required after welding. Adjustment and repair; before and after installation, the 24 Φ22 holes from the plate base are respectively drilled by a radial drilling machine, and there is...
