TRACTION BUFFERING STRUCTURE FOR ALUMINUM ALLOY LOCOMOTIVE BODY

摘要

A traction buffering structure for an aluminum alloy locomotive body, in which a re-railing support plate (12) is provided on a lower cover plate (10), a coupler mounting base I (2) and a coupler mounting base II (3) that are perpendicular to an upper cover plate (1) are provided on the edge of the horizontal surface of the upper cover plate (1), the coupler mounting base I (2) and the coupler mounting base II (3) are fixedly connected to form a coupler mounting base (4), the coupler mounting base (4) is fixedly connected to the upper cover plate (1), the coupler mounting base (4) is provided with a square hole and a bolt hole and is provided with two wing plates (5) on both sides thereof, the coupler mounting base (4) and the two wing plates are fixedly connected to each other, the coupler mounting base (4) is fixedly connected, in the perpendicular direction thereof, to an inner vertical plate I (6), an inner vertical plate II (7), an outer vertical plate I (8) and an outer vertical plate II (9), said four vertical plates are fixedly connected to the upper cover plate (1), and the lower cover plate (10) is snap-fitted onto the two wing plates (5) and is fixedly connected to the wing plates (5). Said buffering structure has a simple structure, a high bearing capacity and a light weight, and requires a small amount of welding, being time-saving, labour-saving and cost-saving, solving the problem of strength, and enhancing the safety performance of said structure.
