Description
Technical Field
The utility model relates to an automobile parts specifically indicates an automobile exhaust system silencer structure.
Background
The state limits the particulate matter emission of gasoline vehicles, so that the particles in the exhaust gas need to be treated. At present, in an exhaust system of a gasoline vehicle, a particle trap is added to trap particles in exhaust gas, and then the trapped particles are ignited again after a certain condition is reached, so that the emission of the particles is reduced. However, due to the structural limitation of the particle catcher assembly, a large arrangement space of the exhaust system is required to be occupied, the exhaust system has a good silencing effect, the volume of the silencer is often large, the occupied space is large, and the particle catcher assembly and the silencer are often arranged in series, so that a longer and larger space is required to be arranged.
Disclosure of Invention
The utility model aims at providing an automobile exhaust system silencer structure, this silencer structure has noise elimination and tail gas particle entrapment function concurrently, can save current particle catcher assembly structure, has saved the arrangement space by a wide margin.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides an automobile exhaust system silencer structure, includes the barrel, the barrel front end even has the front end awl, the barrel rear end even has the rear end awl, the front end is equipped with the particle catcher in the barrel, the rear end is equipped with the baffle in the barrel, even have the perforated pipe for the noise elimination on the baffle.
Further, a liner is plugged between the outer wall of the particle catcher and the inner wall of the cylinder body.
Further, the particle catcher is cylindrical.
Furthermore, the partition plate is arranged on the cross section of the cylinder body, a fixing hole is formed in the partition plate, one end of the porous pipe penetrates through the fixing hole, and the other end of the porous pipe is fixed on the rear end cone.
Furthermore, the perforated pipe is in a hollow cylindrical shape, fine holes are densely distributed on the periphery of the perforated pipe, a flaring is arranged at one end, fixed on the rear end cone, of the perforated pipe, and the diameter of the flaring is larger than that of the front end of the perforated pipe.
The utility model has the advantages of as follows:
the utility model discloses arrange under the limited circumstances in space at exhaust system, provide a new silencer structure, in limited arrangement space, contain the particle catcher promptly, can play the effect that reduces exhaust particle and discharge, contain noise-abatement structure again, can reduce the noise, solved and arranged the not enough problem in space, especially provided a feasible solution of taking into account noise and exhaust particle and discharging under the condition that the length direction in space can not satisfy the requirement of arranging.
Drawings
FIG. 1 is a schematic diagram of an external structure of a muffler structure of an automobile exhaust system.
Fig. 2 is a schematic view of the internal structure of fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, which are not intended to limit the scope of the present invention.
As shown in fig. 1 and 2, the muffler structure of the automobile exhaust system comprises a cylinder 4, wherein the front end of the cylinder 4 is connected with a front end cone 1, the rear end of the cylinder 4 is connected with a rear end cone 7, the front end in the cylinder 4 is provided with a particle catcher 3, the rear end in the cylinder 4 is provided with a partition plate 5, and the partition plate 5 is connected with a porous pipe 6 for muffling.
The particle catcher 3 is cylindrical, and a liner 2 is plugged between the outer wall of the particle catcher 3 and the inner wall of the cylinder 4. The partition plate 5 is arranged on the cross section of the cylinder 4, a fixing hole 5.1 is formed in the partition plate 5, one end of the porous pipe 6 penetrates through the fixing hole 5.1, and the other end of the porous pipe is fixed on the rear end cone 7. The perforated pipe 6 is hollow and cylindrical, the periphery of the perforated pipe 6 is densely distributed with fine holes 6.1, one end of the perforated pipe 6 fixed on the rear end cone 7 is provided with a flaring 6.2, and the diameter of the flaring 6.2 is larger than that of the front end of the perforated pipe 6.
The assembly process of the silencer structure of the automobile exhaust system comprises the following steps: the liner 2 and the particle catcher 3 are plugged into the cylinder 4 and are compressed; then pressing the porous pipe 6 into the fixing hole 5.1 of the clapboard 5; then pressing the assembly of the porous pipe 6 and the baffle 5 into the cylinder 4; respectively welding the front end cone 1 and the rear end cone 7 with the cylinder 4; and finally, flaring the perforated pipe 6, and welding the flared perforated pipe with the rear end cone 7 to form the silencer structure of the automobile exhaust system.
The working process of the silencer structure of the automobile exhaust system is as follows: when exhaust tail gas passes through the structure and firstly passes through the particle catcher 3, particulate matters in the tail gas are adsorbed in the particle catcher 3, and then the tail gas passes through the silencing element consisting of the partition plate 5 and the perforated pipe 6, so that high-frequency noise of the tail gas is weakened, and the silencing effect is achieved.
