Abstract

The present invention relates to a corrugated pipe for national VI commercial vehicles, in particular to the technical field of corrugated pipes, comprising: a main body of the corrugated pipe, straight edge sections are provided at both ends, and a metal winding pipe is embedded in the inner wall of the main body of the corrugated pipe. The outer surface of the metal winding pipe is evenly wrapped with a metal knitted filter to form an insulation layer to reduce the heat conduction of the pipe body. The port of the bellows main body is provided with a metal lining ring to connect the port of the metal winding pipe to the The port of the main body of the bellows is fixed, and a metal outer ring with a protective cover is also provided at the port of the main body of the bellows to prevent the two ends of the main body of the bellows from being bumped by transitional waves, and the outer port of the outer metal ring is connected with a metal flange , the metal flange is used to connect with the exhaust manifold or the muffler; the shape of the inner wall of the bellows is determined by a shape curve formula. The invention effectively improves the treatment efficiency of the bellows for the exhaust of the automobile.

Description

technical field [0001] The invention relates to the technical field of corrugated pipes, in particular to a corrugated pipe for National VI commercial vehicles. Background technique [0002] National VI bellows for commercial vehicles is a device used on commercial vehicles, installed between the exhaust manifold and the muffler, to make the entire exhaust system appear sealed and flexible. The device plays the role of shock absorption and noise reduction, convenient installation, prolonging the life of the exhaust system, and increasing comfort. [0003] At this stage, such manufacturers at home and abroad all use "U" corrugated pipes, "2S", "3S" winding pipes and other structures. With the development of the automobile market, higher requirements are put forward for the device's breakage rate, high flexibility, assembly efficiency, cost reduction and efficiency increase, and the popularization and implementation of the National VI emission standard. Gas treatment efficie...
