Abstract
The utility model discloses an automobile muffler, comprising a casing, an air inlet pipe welded on the casing, an air outlet pipe and perforated baffle plates mounted in the casing, wherein the number of the baffle plates is three and the part of the air outlet pipe in the casing perforates the three baffle plates and one end of the air inlet pipe in the casing perforates the first, second baffleplates in turn along the air inlet direction and is connected with the third baffle plate and a gap for air outlet is arranged on the pipe wall at the connection end. The automobile muffler is mounted on the automobile and more attenuates the high frequency noise of the engine exhaust and the total noise is reduced to 2dv.
Description
Technical field
The utility model relates to automobile technical field, particularly a kind of exhaust silencer of motor car engine.
Background technique
The exhaust silencer of automobile is used for reducing a critical component of automobile engine to exhaust noise, it eliminates noise by the pulsation of reduction, decay exhaust pressure, the exhaust silencer of a superior performance, it can the effective attenuation exhaust sound, can also influence the output power of motor again to greatest extent.The exhaust silencer of existing a kind of minicar, the exhaust silencer of it and other automobile also has the housing of the sealing of suction tude of being provided with and steam outlet pipe, and the separated by spaces in the housing is become to have dilating effect and three chambers of toot effect altogether by two orifice plates, wherein suction tude and steam outlet pipe all pass three chambers in the housing, in the expansion chamber of centre, suction tude and steam outlet pipe are equipped with the tube wall vent, the automotive muffler noise elimination effect of this structure is still good inadequately, and is particularly bad for the decay of high-frequency noise.
Summary of the invention
Problem to be solved in the utility model provides a kind of noise elimination effect automotive muffler preferably.
The scheme that the utility model is taked is: this automotive muffler, include housing, be welded on suction tude, the steam outlet pipe on the described housing and be contained in the interior dividing plate with holes of described housing, described dividing plate has three, the part of described steam outlet pipe in described housing all passed described three dividing plates, the end of described suction tude in described housing passes the described dividing plate of first, second piece successively along airintake direction, and be connected, and on the tube wall of connecting end, be provided with as the breach of giving vent to anger with the 3rd dividing plate.
Such scheme can be more specifically: along airintake direction, in the 4th chamber that is separated out by described dividing plate in the described housing acoustical cotton is housed, the tube wall vent of described suction tude and steam outlet pipe all is located in second chamber that is separated out by described dividing plate; The inner of described suction tude is welding with being connected of described the 3rd dividing plate.
Owing to adopted such scheme, the utility model compared with the prior art, it is the attenuate high frequency noise better, global noise reduces and reaches 2 decibels.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the I-I sectional view of Fig. 1.
Fig. 3 is the II-II sectional view of Fig. 1.
Embodiment
Automotive muffler as shown in Figure 1 has a housing 1, front end at housing 1 is welded with a suction tude 2 that stretches into housing 1 inside, be welded with a steam outlet pipe 6 that stretches into housing 1 inside in the rear end of housing 1, have three dividing plates with holes 3,4,5 that the space in the housing is separated into first, second, third and fourth totally 4 chambers successively along airintake direction in housing 1, the part of steam outlet pipe 6 steam outlet pipes in housing 1 all passed whole dividing plates 3,4,5; Suction tude 2 is passed dividing plate 3,4 successively along airintake direction in housing, its end is welded on the dividing plate 5, and is provided with on its end tube wall as the breach of giving vent to anger.Along airintake direction, acoustical cotton 7 is housed in the chamber behind the dividing plate 5; In the chamber between dividing plate 3 and dividing plate 4, the tube wall of suction tude 2 and steam outlet pipe 6 is equipped with vent.
