Abstract
The utility model relates to a rear silencer assembly which comprises an air inlet pipe, an air outlet pipe and a noise elimination cavity assembly. The noise elimination cavity assembly is composed of a barrel body, a front cover board, a rear cover board, an inlet air buffering pipe and an outlet air buffering pipe, and the noise elimination cavity assembly is divided into a first cavity chamber, a second cavity chamber and a third cavity chamber through a front separating board and a rear separating board. The inlet air buffering pipe penetrates through the front separating board and the rear separating board from the front cover board and stretches into the third cavity chamber, the outlet air buffering pipe penetrates through the rear separating board and the front separating board from the rear cover board and stretches into the first cavity chamber, the air inlet pipe is connected with the inlet air buffering pipe which is placed on the front cover board, and the air outlet pipe is connected with the outlet air buffering pipe which is placed on the rear cover board. By means of a reinforcing rod, reliability and durability of the rear silencer assembly are improved. In addition, an independent pothook which is arranged is connected with a car body, vibration of the car body is transmitted to the silencer assembly to produce the structure noise, and the structure noise is reduced.
Description
Technical field
The utility model relates to a kind of rear muffler assembly, belongs to the silencing apparatus technology.
Background technique
Use on the automobile at present disappear after can increase air-flow velocity, thereby increased the difficulty of noise reduction, soundproof effect is undesirable, simultaneously because the operatic tunes is by three pipes, i.e. suction tude, steam outlet pipe and transition tube, and cylindrical shell, front and rear cover form.Air-flow is delivered on the silencing apparatus by hangar system by the vibrations of transition tube automobile, the construct noise that causes the vent systems body vibration to produce.
The model utility content
The model utility purpose: the purpose of this utility model is for the deficiencies in the prior art, a kind of rear muffler assembly is provided, improve mechanism's intensity of rear muffler assembly, effectively reduce engine exhaust noise, reduce simultaneously the construct noise that the vibrations from car body cause vent systems.
Rear muffler assembly of the present utility model comprises suction tude, outlet pipe, noise elimination cavity assembly; The noise elimination cavity assembly is made of cylindrical shell, front shroud, back shroud, air inlet separator tube, exhaust separator tube, aforesaid noise elimination cavity assembly is separated into the first chamber, the second chamber, the 3rd chamber by front dividing plate and rear bulkhead, the air inlet separator tube passes front dividing plate by front shroud and rear bulkhead stretches into the 3rd chamber, state that the exhaust separator tube passes rear bulkhead by back shroud and front dividing plate stretches into the first chamber, the air inlet separator tube tube wall that is positioned at the first chamber has vent, the exhaust separator tube tube wall that is positioned at the second chamber has vent, all has vent on front dividing plate and the rear bulkhead; Suction tude is connected with air inlet separator tube on being positioned at front shroud, and outlet pipe is connected with exhaust separator tube on being positioned at back shroud.
Aforesaid suction tude downside has the suction tude reinforcing bar that is connected with front shroud, and the outlet pipe downside has the outlet pipe reinforcing bar that is connected with back shroud.
Aforesaid cylindrical shell upper surface middle part has the cavity hook of a pair of symmetry, and outlet pipe has aft hook near the exhaust port side downside.
The beneficial effects of the utility model are: (1) increases noise reduction by three resonant cavities of design; (2) by adopting reinforcing bar to improve mechanism's intensity of rear muffler assembly.

Embodiment
The below is elaborated to technical solutions of the utility model, but protection domain of the present utility model is not limited to described embodiment.
Embodiment:A kind of rear muffler assembly that present embodiment provides, structure comprise suction tude 8, outlet pipe 9, noise elimination cavity assembly as shown in Figure 1; As shown in Figure 2: the noise elimination cavity assembly is by cylindrical shell 2, front shroud 1, back shroud 3, air inlet separator tube 4, exhaust separator tube 5 consists of, aforesaid noise elimination cavity assembly is separated into the first chamber I by front dividing plate 6 and rear bulkhead 7, the second chamber II, the 3rd chamber III, air inlet separator tube 4 passes front dividing plate 6 by front shroud 1 and rear bulkhead 7 stretches into the 3rd chamber III, state that exhaust separator tube 5 passes rear bulkhead 7 by back shroud 3 and front dividing plate 6 stretches into the first chamber I, air inlet separator tube 4 tube walls that are positioned at the first chamber I have vent, exhaust separator tube 5 tube walls that are positioned at the second chamber II have vent, all have vent on front dividing plate 6 and the rear bulkhead 7; Suction tude 8 is connected with air inlet separator tube 4 on being positioned at front shroud 1, and outlet pipe 9 is connected with exhaust separator tube 5 on being positioned at back shroud 3.
Aforesaid suction tude 8 downsides have the suction tude reinforcing bar 10 that is connected with front shroud 1, and outlet pipe 9 downsides have the outlet pipe reinforcing bar 11 that is connected with back shroud 3.
Aforesaid cylindrical shell 2 upper surface middle part have the cavity hook 12 of a pair of symmetry, and outlet pipe 9 has aft hook 13 near the exhaust port side downside.
When specific operation are used, with air inlet separator tube 4, front dividing plate 6, rear bulkhead 7, exhaust separator tube 5 assembly weldings become core assembly, core assembly are welded in the cylindrical shell 2 again, and the cylindrical shell two ends are encapsulated with front shroud 1 and back shroud 3, suction tude 8 and air inlet separator tube 4 are assembled into one, outlet pipe 9 and exhaust separator tube 5 are assembled into one.
As mentioned above, although the specific preferred embodiment of reference has represented and has explained the utility model that it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make in the form and details various variations to it.
