Muffler exhaust pipe with high use ratio

Abstract

The invention discloses a muffler exhaust pipe with the high use ratio. An air pipe body is set to be in a bending shape according to an automobile chassis wiring direction; a support plate is sleevedon an outer shell of the air pipe body; a first vent pipe and a second vent pipe penetrate through the support plate; a support plate through hole is formed in the support plate; a muffler is connected to the air pipe body part near an air outlet head and is connected with the air pipe body through a connecting part; two reducers are arranged on the air pipe body near the air outlet head; the muffler is arranged at a position between the two reducers; the air pipe body is provided with an auxiliary muffler; and three to five bulges are uniformly arranged on an outer surface of the air pipe body along a circumference of a cross section. The replacement of a whole muffler system is prevented, in addition, cutting can be carried out in a groove between each two adjacent bulges in the reducers, damaged parts can be cut, the support plate plays a role in supporting, maintenance personnel can conveniently and accurately judge failed components through the three to five bulges, and the use ratio of the exhaust pipe is improved.

Description

technical field [0001] The invention belongs to the technical field of exhaust pipe equipment, and in particular relates to a high-utilization muffler exhaust pipe. Background technique [0002] The automobile exhaust pipe is an important part of the automobile. Its function is to make the entire exhaust system flexibly connected, so as to reduce vibration and noise, facilitate installation and prolong the life of the exhaust muffler system. Most of the existing automobile exhaust pipes adopt a straight pipe structure. Although the exhaust gas produced by the automobile is silenced by the muffler, the exhaust gas still produces very loud noise when passing through the straight pipe, causing noise pollution. The auxiliary muffler on the side branch of the exhaust system is easily damaged due to the corrosion of acid condensed water, and the existing automobile exhaust pipe does not have any mechanism designed to deal with the corrosion damage. The muffler exhaust system is a...

Problems solved by technology

Most of the existing automobile exhaust pipes adopt a straight pipe structure. Although the exhaust gas generated by the automobile is silenced by the muffler, the exhaust gas still produces very loud noise when passing through the straight pipe, causing noise pollution.

The auxiliary muffler on the side branch of the exhaust system is easily damaged due to the corrosion of acid condensed water, and the existing automobile exhaust pipe does not have any mechanism designed to deal with the corrosion damage. The muffler exhaust system is all replaced with new ones, so that other parts of the exhaust system cannot be used due to tiny corrosion damage, resulting in a great waste
