TRAIN SUSPENSION SYSTEM

摘要

A suspension system for a train vehicle comprises a primary lateral suspension system; and a secondary lateral suspension system, wherein the primary lateral suspension system is arranged to be connected, in use, between a bogie (g) of the train vehicle and at least one wheelset (w) of the train vehicle, the wheelset having an axle which defines a lateral direction, such that the primary lateral suspension system transmits forces between the bogie and the wheelset in the lateral direction; and wherein the secondary lateral suspension system is arranged to be connected, in use, between the bogie (g) and a body (v) of the train vehicle, such that the secondary lateral suspension system transmits forces between the bogie and the body in the lateral direction; the train suspension system further comprising at least one inerter in at least one of the primary lateral suspension system and the secondary lateral suspension system such that the movement of the body in the lateral direction is minimised.
