Description
Technical field
The present invention relates to field of automobile, especially a kind of automobile exhaust muffler.
Background technique
The main function of automobile exhaust muffler is the exhaust noise for reducing engine, and high-temp waste gas is enable to have safely
The discharge of effect ground, the superiority and inferiority of performance directly influence the size of the inside and outside noise of vehicle vehicle.Automobile exhaust muffler used at present
Including the silencer interpolation pipe equipped with noise reduction pipe portion, bloop is distributed on the tube wall of noise reduction pipe portion, is covered on silencer interpolation pipe
Equipped with suppressor case, the both ends of suppressor case and silencer interpolation pipe are welded, in suppressor case and silencer interpolation pipe
Between be equipped with silencing cotton.This automobile exhaust muffler has the disadvantage that the intensity of silencer interpolation pipe in use
Lower, silencer interpolation pipe is coupled with vehicle normal revolution frequency, and vibration transmitting for a long time causes silencer interpolation pipe fatigue disconnected
Failure is split, to generate abnormal sound.
Summary of the invention
The problem to be solved by the invention is to provide a kind of automobile exhaust mufflers, it can solve silencer interpolation pipe
Intensity is lower, and vibration transmitting for a long time causes silencer interpolation pipe fatigue fracture to be failed, to lead to the problem of abnormal sound.
To solve the above-mentioned problems, the technical solution adopted by the present invention is that: this automobile exhaust muffler, including be equipped with disappear
The silencer interpolation pipe in sound tube portion is distributed with bloop on the tube wall of the noise reduction pipe portion, is set on the silencer interpolation pipe
There is suppressor case, silencing cotton is housed between the suppressor case and the silencer interpolation pipe；The silencer interpolation
Pipe is equipped with reinforcing rib equipped with the reinforcement pipe portion that the noise reduction pipe portion is divided into two sections, the reinforcement pipe portion.
In above-mentioned automobile exhaust muffler technical solution, more specific technical solution may also is that the suppressor case
Both ends be respectively equipped with the choke connecting with the silencer interpolation pipe, the outlet side of the silencer interpolation pipe with it is corresponding
Damping, buffering component is housed between the suppressor case choke.
Further, the damping, buffering component is damping, buffering gasket ring, and the damping, buffering gasket ring uses high temperature resistant not
Rust steel wire is made.
Further, the middle part for reinforcing pipe portion forms the contraction that diameter is less than the noise reduction pipe portion diameter to contract
Portion, the reinforcing rib are located at the centre of the contraction flow region.
Further, the reinforcing rib ring is wound on the outside of the contraction flow region.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages:
1, silencer interpolation pipe of the invention reinforces pipe portion and is equipped with reinforcement equipped with the reinforcement pipe portion that noise reduction pipe portion is divided into two sections
Muscle；The integral strength for improving silencer interpolation pipe avoids silencer interpolation pipe from coupling with vehicle normal revolution frequency, for a long time
Vibration transmitting causes silencer interpolation pipe fatigue fracture to be failed, to eliminate generation abnormal sound.
2, damping, buffering component is housed between the outlet side of silencer interpolation pipe and corresponding suppressor case choke；It is logical
Resonance and vibratory impulse that damping, buffering component reduces engine and exhaust silencer are crossed, when preventing switch-off, silencer
Shell and silencer interpolation pipe because wall thickness, intensity, inside and outside cooling velocity it is inconsistent due to generates and cools down noise.
3, damping, buffering component is damping, buffering gasket ring, and damping, buffering gasket ring is made of high temperature resistant stainless steel silk；Structure
Simply, manufacturing cost is low.
4, the middle part for reinforcing pipe portion forms the contraction flow region that diameter is less than noise reduction pipe portion diameter to contract, and reinforcing rib, which is located at, to be received
The centre in contracting portion；The intensity for further enhancing silencer interpolation pipe, prolongs the service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings:
A kind of automobile exhaust muffler as shown in Figure 1, including the silencer interpolation pipe 2 with noise reduction pipe portion 2-1, noise reduction pipe portion
Bloop is distributed on the tube wall of 2-1, suppressor case 1 is set on silencer interpolation pipe 2, in suppressor case 1 and eliminates the noise
Silencing cotton is housed between device interpolation pipe 2.Silencer interpolation pipe 2 has the reinforcement pipe portion 2-2 that noise reduction pipe portion 2-1 is divided into two sections,
Reinforce that reinforcing rib 4 is housed on pipe portion 2-2；The middle part for reinforcing pipe portion 2-2 forms diameter to contract and is less than noise reduction pipe portion diameter
Contraction flow region, reinforcing rib 4 are located at the centre of contraction flow region and are looped around the outside of contraction flow region.The both ends of suppressor case 1 are respectively set
There is a choke connecting with silencer interpolation pipe 2, the outlet side of silencer interpolation pipe 2 and corresponding 1 choke of suppressor case
Between be equipped with damping, buffering component 3, discharge directions are as shown by arrows in figure.The damping, buffering component 3 of the present embodiment is slow for damping
Gasket ring is rushed, damping, buffering gasket ring is made of high temperature resistant stainless steel silk.
Silencer interpolation pipe 2 of the invention has the reinforcement pipe portion 2-2 that noise reduction pipe portion 2-1 is divided into two sections, reinforces pipe portion
Reinforcing rib 4 is provided on 2-2；The integral strength for improving silencer interpolation pipe 2 avoids silencer interpolation pipe 2 and vehicle common
Speed-frequency coupling, vibration transmitting for a long time causes 2 fatigue fracture of silencer interpolation pipe to be failed, to eliminate generation abnormal sound.Disappear
Damping, buffering gasket ring is housed between the outlet side of sound device interpolation pipe 2 and corresponding 1 choke of suppressor case；Pass through damping, buffering
Gasket ring reduces the resonance and vibratory impulse of engine and exhaust silencer, when preventing switch-off, suppressor case 1 and noise elimination
Device interpolation pipe 2 because wall thickness, intensity, inside and outside cooling velocity it is inconsistent due to generate cooling noise.
