Automobile exhaust pipe with good silencing function

Abstract

The invention discloses an automobile exhaust pipe with a good silencing function, and belongs to the technical field of automobile parts. The automobile exhaust pipe comprises a main pipe, an intake pipe arranged at the front end of the main pipe, and a tail pipe located at the tail end of the main pipe, wherein a tail gas purifier is arranged between the main pipe and the tail pipe; a gas flow buffer plate and filter units are arranged in the main pipe; the gas flow buffer plate is arranged at the front end of the filter unit and located at the axis of the intake pipe; the gas flow buffer plate is hooked with the inner wall of the main pipe through a spring; the filter units are alternately distributed in a vertically-staggered manner along the transversal direction; two exhaust branch pipes are arranged on the tail pipe; and each exhaust branch pipe is of a double-layer structure, and uniformly-distributed silencing holes are formed in the tail end of the inner layer. According to the automobile exhaust pipe disclosed by the invention, the tail pipe is divided into the two exhaust branch pipes, thus the gas flow impact of a tail gas is greatly weakened; and meanwhile, the double-layer structure of each exhaust branch pipe is matched with the silencing holes in the tail end, thus the noise of the tail gas can be effectively lowered, and noise pollution is reduced. The automobile exhaust pipe disclosed by the invention is simple in structure, novel in design and great in market competitiveness.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile exhaust pipe with good noise reduction function. Background technique [0002] With the continuous development of my country's economy, motor vehicles have become very popular, and automobiles have entered thousands of households, and motor vehicles are also widely used in industry and agriculture. Automobile exhaust bellows, also known as automobile exhaust pipe hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, and is convenient. The function of installing and prolonging the life of the exhaust muffler system. It is mainly used for light vehicles, miniature vehicles and passenger cars. Its structure is that the double-layer bellows is covered with steel wire mesh sleeves, and the straight edge sections at both ends ar...
