Description

Technical Field

[0001] The present application relates to the field of exhaust center pipes, and in particular to an automobile exhaust center pipe for improving exhaust efficiency. Background Art

[0002] Automobile exhaust pipe bellows (automobile flexible joint) is an important connecting component in the automotive field. It utilizes its own unique air tightness and adopts double-layer hydraulic pressure during molding. With water as the medium, the produced bellows is more conducive to the emission of automobile exhaust gas and reduces the environmental pollution caused by engine exhaust gas to the lowest point. It is used to absorb the vibration of the exhaust system and prevent excessive thermal deformation, thereby providing a comfortable ride. Stainless steel SUS304 is used as the main material of the flexible joint. It can withstand high temperature and salt corrosion. The inside of the bellows can be equipped with a mesh sleeve and an expansion joint, which can eliminate engine noise. Therefore, automobile exhaust pipe bellows (automobile flexible joint) has become the most ideal compensation element in modern industrial supporting pipes.

[0003] The structure of the product can refer to a kind of automobile exhaust bellows disclosed in Chinese patent document 202221419971.6, which includes a bellows body, an air intake pipe connected to one side of the bellows body, an exhaust pipe connected to one side of the bellows body, and a positioning mechanism arranged on the inner side of the bellows body, wherein the exhaust pipe includes an exhaust connection part, a first exhaust guide part, and a second exhaust guide part, wherein the exhaust connection part, the first exhaust guide part, and the second exhaust guide part are fixedly connected in sequence and are an integrated structure. The automobile exhaust bellows can be quickly installed on the air intake pipe part and the exhaust pipe part through the installation part, and the spot welding connector is arranged to effectively play a reinforcing role. The positioning mechanism enables the bellows body to have a positioning function in the case of extremely rapid expansion, reduces the problem of super deformation of the linear bellows, and improves the smoothness of the gas flow in the pipe. The automobile exhaust bellows has a reasonable structure, is easy to install, and has high protection, which improves the mission and performance of the product.

[0004] However, when the exhaust center pipe is connected to the corresponding connecting pipe, since no sealing component is provided, the sealing effect cannot be optimized.

[0005] A vehicle exhaust center pipe for improving exhaust efficiency is now provided. Utility Model Content
