Technical realization elements of lightweight traction beams for heavy-duty trucks

Technical implementation elements:

3. The present invention discloses a lightweight tractor beam composition for heavy-duty trucks according to the requirements of the railway freight car for the design of the traction beam. The traction beam of the invention has a reliable composition structure and convenient maintenance, and can meet the requirements of a longitudinal load of not less than 3500kn and the application requirements of a 10,000-ton marshalling train.

4. the present invention provides following technical scheme realization:

5. A lightweight traction beam composition for heavy-duty trucks, comprising an impact seat, a rear follower plate, and a center plate partition, and is characterized in that:

6. The traction beam is composed of a lower cover plate, two webs symmetrically assembled on both sides of the lower cover plate along the length direction, the top surface and the truck floor are welded into a box-shaped structure;

7. The impact seat is welded and fixed to the front end of the traction beam to form the box-shaped structure, the rear panel is welded and arranged in the middle of the traction beam to form the box-shaped structure, and the center plate partition is arranged on the traction beam to form the box-shaped structure. The rear end and lower part are connected and fixed with the upper center plate;

8. The front part of the lower cover plate is provided with a notch groove suitable for the installation of the impact seat, and the rear part is arranged with a large oblong hole for welding; transition.
