Product overview

Railway car is equipped with spring suspension device to reduce vibration of the train. Spring suspension device determine whether a railway car can run stable and comfortable, whether railway vehicle can trough curve successful. Spring suspension device plays an important role in safety running of rail car.

There`re lots of springs for railway vehicles, Conical rubber spring is one of them. With the advantages of large unit volume and small specific gravity, the rubber spring can eliminate high frequency vibration and improve vibration performance. Because of its changeable rigidity, when it’s installed onto axle box spring suspension device, different positioning stiffness from vertical and horizontal generated. With character of non-linear, the running performance can be improved without extra friction shock absorber.
