About Automotive Rubber Bellows

Automotive rubber bellows are usually made of rubber materials with good properties such as high temperature resistance, oil resistance, and weather resistance, such as nitrile rubber, neoprene, etc. These materials can resist the erosion of various chemicals, such as gasoline, lubricating oil, etc., thereby ensuring the stability and reliability of automotive rubber bellows.

Auto Rubber Bellows

Prinzip der Versiegelung

The sealing principle of automotive rubber bellows mainly depends on the elastic deformation characteristics of the bellows. When the bellows is subjected to external pressure or deformation, the sealing material filled between its inner and outer rings will deform accordingly following the deformation of the bellows. This deformation causes the sealing material inside the bellows to come into close contact with the pipe surface, forming an effective seal.

In addition, the realization of bellows sealing also relies on the sealing material filled between the inner and outer rings of the bellows. These materials usually have a certain degree of flexibility and elasticity, able to adapt to the deformation of the bellows and maintain close contact with the pipe surface.

Main Function

1. Vibration reduction and noise reduction: Rubber bellows has the characteristics of softness, acid and alkali resistance and sound insulation, which can effectively reduce vibration and noise generated during car driving.

2. Convenient installation: The installation method of rubber bellows is flexible and can easily connect various pipelines and equipment to improve installation efficiency.

3. Extend the life of the exhaust noise reduction system: Rubber bellows can be used as a connector for the automobile exhaust system, making the entire exhaust system flexible and extending the service life of the exhaust noise reduction system.

Application scenarios

1. Internal combustion engine: In automobile internal combustion engines, bellows are widely used in exhaust pipe systems as an important part of conveying high-temperature exhaust gas and reducing engine noise.

2. Turbocharger: Between the intake/exhaust air in the turbocharger and the exhaust gas turbine/middle exhaust system, leakage is prone to occur due to factors such as temperature, pressure and vibration. Automotive rubber bellows are installed in the exhaust pipe system, which can effectively alleviate vibration amplitude and reduce noise, and also have a certain degree of corrosion resistance.

3. Clutch: In the clutch system, the bellows is an important part of some automobile shock absorbers, which can alleviate the transmission of engine vibration to the transmission. Bellows are placed at both ends of the clutch piston rod to dampen vibration. At the same time, the excellent elastic properties of the bellows can reduce the noise from the engine.

4. Industrial field: Rubber bellows are widely used in the industrial field and can be used to transport various liquids, gases and granular materials. Due to its good elasticity, high temperature resistance and corrosion resistance, it can be used in petroleum, chemical industry, pharmaceutical, food and other fields. In the petroleum and chemical industries, rubber bellows are often used to transport various greases, acids, alkalis and other substances; in the pharmaceutical and food fields, rubber bellows are used to transport pharmaceuticals, food, beverages, etc.

Tägliche Wartung

1. Regularly check the joints of bellows: The joints of bellows are the main source of leakage. Therefore, it is necessary to regularly check the sealing condition of the joints of bellows, replace the sealing material or adjust the connection method in time.

2. Prevent corrugated pipe corrosion: During use, automotive rubber bellows must avoid contact with corrosive substances such as chemicals, water vapor, and long-term exposure to moisture, high temperature, high pressure, and other environments. At the same time, regular cleaning and anti-corrosion treatment of bellows can effectively extend the service life of bellows.

3. Control the frequency of use of corrugated pipes: Bellows are prone to fatigue during frequent bending and expansion. Therefore, it is necessary to control the frequency of use of corrugated pipes and reduce the number of bends and expansions.

4. Keep the bellows clean: Regularly clean the dirt and debris on the surface of the automotive rubber bellows to prevent it from affecting the normal operation of the bellows.

5. Regularly check the elasticity of the bellows: Regularly check the elasticity of the bellows to ensure that it can work properly. If the bellows is found to be insufficiently elastic, it should be replaced in time.

6. Avoid excessive bending and stretching: During installation and use, excessive bending and stretching of the bellows should be avoided to prevent deformation or damage.
