What is the air chamber rubber diaphragm?

The air chamber rubber diaphragm is a seal that transmits the power of compressed air in the spring brake air chamber. The compressed air pushes the push rod through the air chamber rubber diaphragm to provide a key component of the vehicle with braking torque. The air chamber rubber diaphragm is mainly used in the braking systems of commercial vehicles, subways, and high-speed railways. In April 2016, the company signed an agreement with CSR Qingdao Sifang to jointly develop rubber diaphragms for air brake chambers for high-speed railways.
