Air Spring Applied on Bogie

Product Description

1.Product Description
  Air springs are used in the secondary suspensions of rail vehicles. The air spring system is usually composed of a bellow, top plate, sliding plate and auxiliary spring. The bellow consists of cord layers, rubber layers and steel wire to improve strength. These three materials together increase the inflated performance of the bellow.
  The air spring's main functions include supporting the weight of the vehicle, and providing vertical, lateral, and bogie rotation flexibility. The air spring also levels the car to the correct height under varying passenger loads. A height adjustment system installed with the air springs ensure that the car will be level with the railway platform no matter how many passengers get on or off the rail car.
