Abstract
The utility model discloses an automobile muffler assembly consisting of a cavity body, an air inlet pipe and an exhaust pipe. The cavity body is widthwise arranged. The air inlet pipe of the muffler is equipped at the middle portion of the cavity body of the muffler. The exhaust pipe is equipped at a side portion of the cavity body of the muffler. The utility model is suitable to widthwise arrange the cavity body of the muffler, can simplify the structure of the exhaust pipe, lowers the manufacturing cost and reduces the gas flow resistance.
Description
Technical field
The utility model relates to field of automobile, more specifically to a kind of muffler assembly of lateral arrangement.
Background technique
Assemblies such as the vent systems of existing automobile is managed before comprising exhaust, back pipe, purifier, silencing apparatus are formed.Mostly automotive muffler is to adopt the silencing apparatus of lateral arrangement can only make outlet pipe satisfy the turnover gas requirement of silencing apparatus by the form that adds bend pipe from its two ends turnover gas to part at present.Manufacture cost and gas circulating resistance have so just been increased.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of automobile sound absorber assembly that can reduce the lateral arrangement of manufacture cost and gas circulating resistance.
The utility model comprises cavity, suction tude, outlet pipe, and the cavity lateral arrangement is characterized in that: the suction tude of silencing apparatus is located at the middle part of silencing apparatus cavity, and outlet pipe is located at the end of silencing apparatus cavity.
Above-mentioned cavity is the multi-cavity chamber that order is communicated with, and the outlet side of outlet pipe is located on the end that occupy an end chamber, and the other end is located in the chamber that occupy the other end, and suction tude is led to the end and is provided with in the adjacent chamber of the chamber of outlet side.
The through hole that directly is discharged into next chamber with gas in the chamber that suction tude communicates is provided with the spring body valve, and valve body is on the dividing plate between two chambeies.
The spring body valve is made up of spring, rotating shaft, valve plate, and spring is the button spring that control rotating shaft is rotated, and valve plate is installed in the rotating shaft, and it is being attached on the through hole of the dividing plate between two chambeies under the effect of elastic force.
The utility model is located at the suction port of silencing apparatus at the middle part of silencing apparatus cavity at silencing apparatus cavity lateral arrangement.The structure of outlet pipe be can simplify, manufacture cost and gas circulating resistance reduced.If be provided with the state valve in the morning by spring body control folding in the silencing apparatus cavity, the cross section of pass through that door can be regulated air-flow automatically according to the different power of motor and air displacement reaches the effect of optimizing noise reduction and reduction exhaust back pressure.
Description of drawings
Accompanying drawing is the acoustic wave filter structure schematic representation among the embodiment.
Among the figure: 1, dividing plate with holes, 2, inlet end, 3, suction tude, 4, chamber II, 5, inlet hole, 6, spring body valve plate, 7, spring body, 8, chamber III, 9, outlet pipe, 10, the outlet side, 11, chamber I, 12, chamber IV, 13, the through hole on chamber III and the chamber II dividing plate, 14, the rotating shaft of band button spring.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment
Cavity among the embodiment in the silencing apparatus comprises four chamber I, II, III, IV, four chambeies are linked in sequence, be provided with dividing plate with holes 1 between chamber and the chamber, the suction tude 3 that is provided with inlet end 2 is positioned at chamber II4, and suction tude 3 is provided with inlet hole 5, is provided with spring body valve 7 on the chamber II4 of the side of chamber III8 and the dividing plate 1 between the III8 of chamber, spring body valve 7 has a valve plate 6, valve plate 6 can be equipped with the button spring around a rotating shaft 14 rotations in the rotating shaft 14, its rotary state is controlled by the button spring.Valve plate 6 correspondences the through hole on chamber III and the chamber II dividing plate, and through hole 13 is provided with the shirt rim of playing the valve plate leading role, and valve plate 6 is attached in the shirt rim of through hole 13 under the effect of button spring force.
The outlet side 10 of outlet pipe 9 is located on the I11 of chamber, and the other end is located in the IV12 of chamber.Pipe directly leads to the silencing apparatus that is positioned at automobile rear (fuel tank position) after the exhaust from the chassis, is connected with the suction tude 3 of the silencing apparatus of lateral arrangement, and air-flow enters silencing apparatus and eliminates the noise.And, making the exhaust pipe structure complexity if adopt the mode of an end air inlet will need outlet pipe is made U-shaped, manufacture cost increase and gas communication resistance are big.
Brief description is the working principle of silencing apparatus once.
Air-flow enters chamber II4 from the suction tude 3 that is positioned at the silencing apparatus middle part, and along with air-flow constantly increases, air-flow can enter III chamber 8 and IV chamber 12 by the inlet hole on the dividing plate 15; When gas capacity acquires a certain degree, can output to outlet side 10 by outlet pipe 9.When engine power or discharge capacity increase, the pressure that air-flow acts on chamber I, chamber II strengthens, when chamber II pressure acquires a certain degree, just can push spring body valve 6 open, air-flow enters in the III chamber 8, thereby passage section is increased, thereby reaches the effect of regulating noise and reducing exhaust back pressure.
