The structural improved muffler for the automobiles solves the technical problems that an existing technical design is not reasonable enough and the like. The structural improved muffler for the automobiles comprises a muffler body with a cavity, a gas inlet pipe communicated with the cavity is arranged at one end of the muffler body, and an exhaust pipe communicated with the cavity is arranged at the other end of the muffler body. The structural improved muffler for the automobiles is characterized in that muffler pipes are arranged in the muffler body, the muffler pipes are located in the cavity and are communicated with the outlet end of the gas inlet pipe and the inlet end of the exhaust pipe respectively, two inclined sound insulation plates are arranged on the inner wall of the muffler body, the sound insulation plates are sleeved on the muffler pipes respectively, and a buffer plate is further arranged in the muffler body, wherein the buffer plate can divided the cavity into a first buffering cavity and a second buffering cavity and is located between the two sound insulation plates. Compared with the prior art, the structural improved muffler for the automobiles has the advantages of being simple in structure and good in sound reduction effect.
Description
Technical field
The utility model belongs to the auto parts machinery technical field, especially relates to a kind of structure-improved baffler for automobile.
Background technique
Development along with economy, people are also more and more higher to the quality requirement of environment, and automobile is a kind of comparatively common means of transportation, it has the effect of raising the efficiency, and the baffler of automobile its be important parts, the noise pollution that is conducive to reduce behind the baffler in the vehicle traveling process is installed, make sound become soft pleasing to the ear, in order to reduce noise, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of automobile muffler made of new material [application number: 200820227145.5], it comprises with stainless steel material or glass fiber reinforced plastics composite material making silencer casing, make the baffler inner bag with asbestos or pottery, glass fiber reinforced plastics composite material, and design different shapes according to the spatial depiction of various types of automobiles baffler position, do the volume of large baffler as far as possible, can improve significantly erasure effect.Inner bag vertically has at least two-layer, laterally has three layers at least, and some position of the inner bag of special shape can have more multi-layered.The inwall of shell has affixed ring plate, and ring plate is corresponding with the grooved steel disc on the inner bag, the inner bag shell of packing into from the rear portion, and the grooved steel disc namely inserts in the ring plate of outer casing inner wall.This scheme has been improved prior art to a certain extent, and still, at least still there is following defective in this scheme: complex structure, be difficult for manufacturing and cost high, and in addition, its erasure effect is undesirable, or has very large noise.
The model utility content
The purpose of this utility model is for the problems referred to above, and a kind of structure-improved baffler that is used for automobile of simple in structure and good muffling effect is provided.
For achieving the above object, the utility model has adopted following technical proposal: this structure-improved baffler that is used for automobile comprises the muffler body with cavity, end at muffler body is provided with the suction tude that is communicated with cavity, the other end is provided with the outlet pipe that is communicated with cavity, it is characterized in that, be provided with the hush tube that is positioned at described cavity and is communicated with suction tude outlet side and outlet pipe inlet end respectively in the described muffler body, be provided with two sound insulation dishes that are obliquely installed and are enclosed within respectively on the hush tube at the muffler body inwall, also be provided with in the described muffler body and described cavity can be separated into the first buffer cavity and the second buffer cavity and the buffer disc between described sound insulation dish.Obviously, the utlity model has simple in structure, low cost of manufacture and be easy to the advantage such as installation, in addition, noise is very little during its work, practicability is very strong, good muffling effect and meet the development trend of current social technology.
At the above-mentioned structure-improved baffler that is used for automobile, described hush tube is provided with some sound attenuation holes, is respectively equipped with some through holes at each described sound insulation dish.
At the above-mentioned structure-improved baffler that is used for automobile, described buffer disc be obliquely installed and true dip direction identical with sound insulation dish true dip direction.
At the above-mentioned structure-improved baffler that is used for automobile, weld between described sound insulation dish and the muffler body and be connected, weld between buffer disc and the muffler body and be connected.
Compared with prior art, this advantage that is used for the structure-improved baffler of automobile is: simple in structure, and low cost of manufacture and be easy to the advantage such as installation, in addition, noise is very little during its work, and practicability is very strong, good muffling effect and meet the development trend of current social technology.
