Abstract

The embodiment of the present application provides an end corner post and an end wall of a rail train, a rail train. The end corner post includes: a support post, the cross section of the support post has a concave structure; and a cover plate, the cover plate is fixed on the end of the concave structure of the support post. The end wall includes the aforementioned end corner posts. The rail train includes the above-mentioned end wall. The embodiments of the present application are used to solve the technical problem of high integrity of the traditional corner post structure.

Description

technical field [0001] The present application relates to the technical field of electric locomotives, in particular, to an end corner post and an end wall of a rail train, and a rail train. Background technique [0002] Rail transit is an important mode of transportation in my country, carrying a huge amount of traffic. The end corner posts are the key skeleton components of high-speed trains, which play an important bearing role and affect the aerodynamic performance of the vehicle. The traditional end corner columns generally use thin-walled rectangular steel pipes, and the ends are sealed and welded. The compression and load-carrying capacity of conventional end-corner columns is determined by the rectangular steel tube. If the end corner column adopts a rectangular steel pipe with a bearing capacity limit of 200 kN, then any position of the end corner column can only carry 200 kN. [0003] Therefore, the integrity of the traditional corner post structure is relativel...
