Abstract
The utility model discloses a dual exhaust pipe, comprising a three-way connecting pipe (1) and two exhaust pipes (2) which are respectively connected with the two outlet ends of the three-way connecting pipe (1). The dual exhaust pipe is characterized in that the outlet ends of the two exhaust pipes (2) are respectively provided with a curled edge (2.1) which bends inwards to the pipe and is used for reinforcement; a silencing mesh pipe (3) is arranged in each of the two exhaust pipes (2); the top end of the silencing mesh pipe (3) is connected with the curled edge of the outlet end of the corresponding exhaust pipe (2); and the bottom end of the silencing mesh pipe (3) is connected with the inlet end of the corresponding exhaust pipe (2). The dual exhaust pipe disclosed by the utility model has the characteristics of capability of reducing noises in the waste gas emission process and better strength of the outlet ends of the exhaust pipes.
Description
Technical field:
The utility model relates to a kind of body that is used to discharge automobile exhaust gas, specifically is a kind of twin exhaust pipes.
Background technique:
Twin exhaust pipes is a kind of tail pipe that is used to discharge automobile exhaust gas, and this twin exhaust pipes generally comprises right two outlet pipes of a first from left, and these two outlet pipes are connected on a three-limb tube two outlet end of (including two outlet end and an entry end).
In the actual exhaust air process; All discharge fast because of waste gas, can produce certain noise, and the outlet end of two outlet pipes is produced bigger impact dynamics from two outlet pipes of twin exhaust pipes; So in design process, it is particularly important that the noise reduction effect of twin exhaust pipes and intensity seem.
The model utility content:
The utility model technical issues that need to address are: a kind of noise and exhaust outlet end intensity twin exhaust pipes preferably that reduces is provided.
For solving the problems of the technologies described above; The utility model adopts a kind of like this twin exhaust pipes; It comprises a three-limb tube, two outlet pipes that are connected with two outlet end of three-limb tube respectively, and the outlet end of described two outlet pipes all forms the crooked crimping that plays reinforing function in body; Be equipped with the noise reduction webmaster in described two outlet pipes, the top of described noise reduction webmaster is connected with the crimping of corresponding exhaust outlet end, and the bottom of described noise reduction webmaster is connected with the entry end of corresponding outlet pipe.
Described noise reduction webmaster is the thin-walled body that an outer circle wall is provided with some noise reduction through holes.
The utility model compared with prior art; Have the following advantages: on the one hand the noise reduction webmaster is provided with the noise that is produced when waste gas discharged and can plays effective noise reduction effect; The setting of crimping can make the intensity of exhaust outlet end increase on the other hand, has prolonged the working life of the twin exhaust pipes of the utility model.
As improvement, described noise reduction webmaster is the thin-walled body that an outer circle wall is provided with some noise reduction through holes, and is in light weight, noise reduction effect good.
Description of drawings:
Accompanying drawing is the structural representation of a kind of twin exhaust pipes of the utility model.
Shown in the figure: 1, three-limb tube, 2, outlet pipe, 2.1, crimping, 3, the noise reduction webmaster, 3.1, the noise reduction through hole.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Shown in accompanying drawing, a kind of twin exhaust pipes of the utility model, it comprises a three-limb tube 1, two outlet pipes 2 that are connected with two outlet end of three-limb tube 1 respectively.The outlet end of described two outlet pipes 2 all forms the crooked crimping 2.1 that plays reinforing function in pipe, and this crimping 2.1 is formed rank street, crooked back face semicircular in shape in pipe.Be equipped with noise reduction webmaster 3 in described two outlet pipes 2, described noise reduction webmaster 3 is the thin-walled body that an outer circle wall is provided with some noise reduction through holes 3.1.The top of every noise reduction webmaster 3 all is connected through welding with the crimping of the outlet end of corresponding outlet pipe 2, and the bottom of every noise reduction webmaster 3 all is connected through welding with the entry end of outlet pipe 2 accordingly.
Twin exhaust pipes is on the one hand owing to all be provided with noise reduction webmaster 3 in two outlet pipes 2; And being an outer circle wall, noise reduction webmaster 3 is provided with the thin-walled body of some noise reduction through holes 3.1; When waste gas was discharged in outlet pipe 2, the noise when noise reduction webmaster 3 just can effectively reduce the waste gas discharge played the effect of noise abatement like this; On the other hand owing to the outlet end at two outlet pipes 2 all forms the crooked crimping 2.1 that plays reinforing function in pipe; The intensity that the outlet end that has strengthened outlet pipe 2 is set of this crimping 2.1 strengthens the shock-resistant dynamics of the outlet end of outlet pipe 2, has prolonged the working life of twin exhaust pipes.
Claims (2)
1. twin exhaust pipes; It comprises a three-limb tube (1), two outlet pipes (2) that are connected with two outlet end of three-limb tube (1) respectively; It is characterized in that the outlet end of described two outlet pipes (2) all forms the crooked crimping (2.1) that plays reinforing function in pipe; Be equipped with noise reduction webmaster (3) in described two outlet pipes (2), the top of described noise reduction webmaster (3) is connected with the crimping of corresponding outlet pipe (2) outlet end, and the bottom of described noise reduction webmaster (3) is connected with the entry end of corresponding outlet pipe (2).
2. a kind of twin exhaust pipes according to claim 1 is characterized in that: described noise reduction webmaster (3) is the thin-walled body that an outer circle wall is provided with some noise reduction through holes (3.1).
