Document Type and Number:
WIPO Patent Application WO/2021/051452
Kind Code:
A1
Abstract:
Provided is an anti-collision structure for the front end of a railway vehicle chassis, the structure comprising an end beam (1), a side beam (3), a buffer beam (2) and a coupler mounting beam (4). The end beam (1) is a box-shaped structure and is provided with a mounting beam (110), a back plate (111), an upper cover plate (18) and a lower cover plate (19). The mounting beam (110) is provided with mounting holes (11) through which guide pipes (91) of anti-creepers (9) pass, bolt holes (15) are arranged around the mounting holes (11), and the thickness is increased at regions of the mounting beam (110) around the mounting holes (11). Guide cylinders (17) and bolt mounting pipes (14) which are mounted on the mounting beam (110) and the back plate (111) are provided at the interior of the end beam (1); the front ends of the guide cylinders (17) abut against the mounting holes (11), and the front ends of the bolt mounting pipes (14) abut against the bolt holes (15); oblique rib plates (16) are further provided at the interior of the end beam (1); and outer ends of the mounting beam (110), the upper cover plate (18) and the lower cover plate (19) are welded with the side beam (3). The described structure has a compact design, the means of force transmission is ingenious, the weight of an anti-creeper mounting structure (end beam) is reduced due to the lightweight design in which weight reduction holes are additionally provided on internal rib plates, and 400 KN of longitudinal force may be effectively borne and said structure will not yield under 200 KN of vertical force.
