Description

Technical Field

[0001] The utility model relates to the technical field of spring brake air chambers, in particular to an inner breathing piston type spring brake air chamber. Background Art

[0002] A spring brake chamber is a device used in a braking system, usually in large vehicles or mechanical equipment. It includes a spring device and an air chamber to control the operation of the braking system. The working principle of the spring brake chamber is to generate braking force by compressing and releasing the spring. When the brake pedal is pressed, the gas in the air chamber is compressed, thereby compressing the spring. When the pedal is released, the spring releases energy and pushes the brake to apply braking force. This braking system has the advantages of quick response, large braking force, and high reliability. It is suitable for occasions that require high-intensity braking. It is usually used in large trucks, tractors, construction machinery and other vehicles and equipment.

[0003] In the prior art, during the use of the spring brake air chamber, the air pipe input thereto may fall off due to intense driving of the vehicle, which may cause a change in the braking effect. Based on this problem, we propose an internal breathing piston spring brake air chamber. Utility Model Content
