There are two typical spring brake chambers, one is a double diaphragm spring brake chamber, and one is a combined spring brake chamber.
The use of double diaphragm spring brake chamber consists of two independent diaphragm chamber, respectively by the driving brake and parking brake or emergency brake components to operate independently, it is used to provide braking force for the wheel.
The combined spring brake chamber is used to provide braking force for wheels. It is composed of two parts, diaphragm brake part is used for driving brake, spring brake part is used for emergency brake and parking brake, and spring brake part and diaphragm brake part are completely independent of the work.
