Product overview
As a primary axle spring, chevron spring has the advantages of light weight, simple structure, high frequency vibration absorption, noise reduction etc. Therefore, it usually used on railway modern coach.
The primary suspension with chevron spring, because the chevron spring installed on the axle box slantly, its deviation of dimensions and hardness have important influence on the installation height of frame. In order to ensure the bogie with chevron spring can operate safety, the dimensions of primary suspension`s parts should be controlled strictly.
