ELASTIC AXLE FOR PREVENTING DERAILMENT OF RAILWAY VEHICLE

摘要

PURPOSE: A flexible axle for preventing derailment of a railway vehicle is provided to prevent the train from being derailed during high-speed traveling by reducing lateral force to the wheel in passing the curved line with installing an elastic support axle between separable axles. CONSTITUTION: An elastic axle comprises a rectangular installation frame(11) placed in the lower part of a bogie frame and composed of plural axle installation holes formed symmetrically at both sides; separable axles(2,2') separated in the center of the axle and mounted in the installation frame with forming a fixing unit(22) at the side of the wheel; and a support axle(3) having a set of symmetrical containing holes(31) for storing the separation portion of the axle, and an elastic body(4) installed in the containing hole. The derailment of the railway vehicle is prevented by decreasing lateral pressure in traveling on the curved line.
