Description

Technical Field

[0001] This utility model relates to the field of design and manufacturing technology of brake components for commercial vehicles, and specifically to a novel brake chamber. Background Technology

[0002] For the driving safety of commercial vehicles, the reliable operation of the braking system is particularly important. It mainly relies on external mechanical power such as air pressure and hydraulic pressure to convert power into braking force, thereby realizing the action of the brake and the braking of the vehicle. Among them, air pressure braking has been widely used in the field of heavy commercial vehicles due to its advantages of fast braking response, large braking torque and simple braking principle and structure.

[0003] Air brakes rely on the spring force and air pressure in the brake chamber to actuate the brake. The brake chamber includes a driving actuation chamber and a parking actuation chamber that are connected and fixed by an intermediate connecting device. Under the action of external air pressure, parking or driving braking is achieved. However, during the braking process, due to the tiny air gap between the driving chamber and the parking chamber, a small amount of gas will surge at high speed, which can easily generate braking noise or abnormal sounds, seriously affecting the vehicle's driving quality and driving safety. Utility Model Content

[0004] Therefore, this utility model provides a novel brake chamber that can overcome the defects of conventional brake chambers in the prior art, which cause abnormal braking noise or audible noise due to abnormal gas movement between the parking chamber and the driving chamber.

[0005] To address the aforementioned problems, this utility model provides a novel brake chamber, comprising a parking chamber, a driving chamber, and an intermediate connecting body that are arranged in a continuous manner. The intermediate connecting body is disposed between the parking chamber and the driving chamber and is connected and fixed by a clamp. An air inlet is provided on the periphery of the intermediate connecting body. A parking brake piston is disposed inside the parking chamber. The parking brake piston is pushed by a built-in spring or by high-pressure gas entering through the air inlet to realize parking braking or release parking braking. A venting device connected to the parking chamber is provided on the outer peripheral wall of the parking chamber to allow high-pressure gas to escape from the brake chamber to the outside of the brake chamber.

[0006] In some embodiments, the ventilation device is a vent plug, a three-way conduit, or a spiral ventilation hose.

[0007] In some embodiments, the ventilation device is mounted on a pipe support.

[0008] In some embodiments, the pipe support is disposed on the top of the braking chamber for securing the three-way conduit or the spiral ventilation hose.

[0009] This utility model provides a novel brake chamber in which the parking chamber and the driving chamber are connected by an intermediate connector, allowing for independent operation. Furthermore, by adding a venting device to the parking chamber of the brake chamber, high-speed gas surges generated during braking can be quickly discharged without altering the existing chamber structure, reducing braking noise or abnormal sounds caused by high-speed gas surges, thus effectively improving vehicle ride quality and driving safety.

[0016] See also Figures 1 to 4 As shown in the figure, according to an embodiment of the present invention, a novel brake chamber is provided, including a parking chamber 1, a driving chamber 2, and an intermediate connecting body 3 that are arranged through each other. The intermediate connecting body 3 is disposed between the parking chamber 1 and the driving chamber 2 and is connected and fixed by a clamp 5. An air inlet 6 is provided on the periphery of the intermediate connecting body 3. A parking brake piston is disposed in the parking chamber 1. The parking brake piston is pushed by a built-in spring or high-pressure gas entering through the air inlet 6 to realize parking braking or parking brake release. A venting device 4 is provided on the outer peripheral wall of the parking chamber 1 and communicates with the parking chamber to exhaust the high-pressure gas inside the brake chamber to the outside of the brake chamber. The parking chamber 1 and the driving chamber 2 are connected by the intermediate connecting body 3, which can realize independent operation of each other. Furthermore, by adding a ventilation device 4 to the parking chamber 1 of the brake chamber, the high-speed gas generated during braking can be quickly discharged without changing the existing chamber structure, thereby reducing braking noise or abnormal sounds caused by high-speed gas movement and effectively improving the vehicle's driving quality and safety.

[0017] Specifically, a built-in spring pushes the piston forward, extending the air chamber push rod 7 to achieve parking brake operation. High-pressure gas entering through the air inlet 6 pushes the piston in the opposite direction, causing the air chamber push rod 7 to retract and releasing the brake.

[0018] In one specific embodiment, the ventilation device 4 is a vent plug, a three-way conduit, or a spiral ventilation hose.

[0019] In one specific embodiment, the ventilation device 4 is mounted on the pipe support 8.

[0020] In one specific embodiment, the pipeline support 8 is disposed on the top of the braking chamber and is used to fix the three-way conduit or the spiral ventilation hose.
