Abstract

The utility model discloses an exhaust silencer for a high-capacity automobile, which comprises a barrel body, an air-inlet end cover plate and an air-outlet end cover plate, wherein the air-inlet end cover plate and the air-outlet end cover plate are arranged at two ends of the barrel body. Four core pipes and three separating discs are parallelly arranged along the axial direction of the barrel body. One end of a second core pipe is connected with the air-inlet end cover plate, a sleeve pipe is arranged on the second core pipe, sound-absorbing materials are installed between the sleeve pipe and first small holes, a blocking sound-absorbing cavity is formed, and accordingly the good effect of eliminating high frequency is achieved. The other end of the second core pipe sequentially penetrates through a first separating disc and a second separating disc to be arranged corresponding to a third separating disc. One end of a first core pipe is connected with the air-outlet end cover plate, and the other end of the first core pipe sequentially penetrates the third separating disc, the second separating disc and the first separating disc to be arranged corresponding to the air-inlet end cover plate. A third core pipe penetrates through the third separating disc, and two ends of the third core pipe are arranged respectively corresponding to the air-outlet end cover plate and second separating disc. The third core pipe is provided with another sleeve pipe, and sound-absorbing materials are installed between the sleeve pipe and second small holes, another blocking sound-absorbing cavity is formed, and accordingly the high-frequency noises are further lowered. A fourth core pipe penetrates through the three separating discs, and two ends of the fourth core pipe are arranged respectively corresponding to the air-inlet end cover plate and the air-outlet end cover plate.

Description

A kind of big volume automobile exhaust muffler
Technical field
The utility model relates to vehicle, relates in particular to the vent systems of automobile, particularly a kind ofly is used for petrolic big volume automobile exhaust muffler.
Background technique
The effect of automotive muffler is the noise that reduces engine producing, reduces vibration, improves the travelling comfort that automobile uses; The protection environment, the structure of silencing apparatus is in the middle of the silencer cylinder core body pipe to be arranged in the existing technology, core body pipe two ends connect steam outlet pipe and suction tude respectively; Suction tude is connected inlet flange more respectively and gives vent to anger flange with steam outlet pipe, is uniformly distributed with circular hole on the core body pipe, and air communication is crossed circular hole turnover core body pipe; Flow each other, collide and reduce acoustic energy, but the core body pipe is single in the existing technology, the air current flow collisional quenching is little; Thereby cause sound deadening capacity little, low-frequency noise is bigger, influences the travelling comfort of car load.
The model utility content
The utility model purpose is to the defective that existing technology exists a kind of big volume automobile exhaust muffler to be provided.
The utility model adopts following technological scheme for realizing above-mentioned purpose:
A kind of big volume automobile exhaust muffler of the utility model; The inlet end cover plate and the outlet side cover plate that comprise cylindrical shell and be arranged at the cylindrical shell two ends; In cylindrical shell along drum shaft to being set up in parallel four core pipes; And to three separated dishes are set barrel is divided into four cavitys along drum shaft in the cylindrical shell, wherein an end of the second core pipe is connected with the inlet end cover plate, and the other end passes first, second successively at a distance from dish back and the corresponding setting of the 3rd separated dish; One end of the first core pipe is connected with the outlet side cover plate, and the other end passes the 3rd, second, first successively at a distance from the dish corresponding setting with the inlet end cover plate in back; The 3rd core pipe pass the 3rd at a distance from the dish, two ends respectively with the outlet side cover plate and second at a distance from the dish corresponding setting; The four-core pipe pass three at a distance from the dish, two ends respectively with the corresponding setting of inlet end cover plate and outlet side cover plate.
Be positioned at first, second at a distance from dish first, second, along the circumferential direction evenly be provided with a plurality of apertures on the four-core pipe.
Around said second the above aperture of core pipe first sleeve pipe is set, the cotton of eliminating the noise is set between first sleeve pipe and the aperture.
Be positioned at second, third and on the four-core pipe of dish, along the circumferential direction evenly be provided with a plurality of apertures.
Around the aperture on the said four-core pipe second sleeve pipe is set, between second sleeve pipe and the aperture glass fibre is set.
Being positioned at second, third first core pipe at a distance from dish is circular arc.
The utility model air-flow flows into four core pipes, and in four Seal cages back and forth in the process of flowing, air-flow bumps against, and produces friction with pipe fitting, attenuating acoustic energy, thereby reducing noise.
