Abstract

An anti-derailment apparatus for a bogie of a rail vehicle of the disclosure comprises at least one mounting seat and an anti-derailment slide plate. The transverse orientation of the anti-derailment slide plate on the mounting seat and the extending length of the anti-derailment slide plate in the vertical direction meet the following requirements simultaneously: 1) making the anti-derailment slide plate located at the inside of the ground rail when the rail vehicle runs normally; 2) when at least one wheelset of the rail vehicle climbs rail, the anti-derailment slide plate acts on the ground rail to form lateral limitation points so as to limit the freedom of the rail vehicle and make it still constrained by the ground rail.
