Abstract
The invention discloses an exhaust barrel which comprises a silencing tube, a front tube and a rear tube, wherein the front tube and the rear tube are connected together through the silencing tube, the outer surface of the silencing tube is winded with a cooling water pipe, and the outer side of the cooling water pipe is wrapped with heat-resistant sound insulating cotton. Optimally, the sound insulating cotton is sleeved with a metal fixing sleeve. The exhaust barrel has the advantages of being good in sound insulating effect, simple in structure and low in cost.
Description
Technical field
The present invention relates to motor vehicle fittings technical field, especially relate to a kind of exhaust pipe.
Background technique
Exhaust pipe is the indispensable vitals of Motor Vehicle.Usually, exhaust pipe includes hush pipe, and by front and rear tube that hush pipe links together.Certainly, front pipe is used for connecting engine, rear pipe is used for Exhaust Gas.But people expect that the effect of sound insulation tube constantly promotes.
Summary of the invention
The object of this invention is to provide a kind of exhaust pipe, it is better that it has soundproof effect, and simple, the lower-cost feature of structure.
The technical solution adopted in the present invention is: exhaust pipe, comprises hush pipe, and by the front and rear tube that hush pipe links together, described hush pipe outer surface is wound with water-cooling tube, and the outside of this water-cooling tube is enclosed with heat resistant type Sound-proof material.
The outer cover of described Sound-proof material has the fixed cover of metal.
The present invention is compared to the prior art advantageously: soundproof effect is better, and structure is simple, cost is lower.Obviously, outside sound insulation tube or inside Sound-proof material is set, good soundproof effect can be played.But, even if the Sound-proof material of heat resistant type, when being used to exhaust pipe, be also faced with the bottleneck problem that serviceability temperature is too high.Exhaust pipe of the present invention improves for cooling, that is, be wound around water-cooling tube in the outside of hush pipe.Like this, under the effect of water-cooling tube, the operating ambient temperature residing for Sound-proof material obtains very big reduction, thus Sound-proof material can be applied on exhaust pipe.Meanwhile, the parts that such exhaust pipe increases are easy to obtain, and do not make larger change relative to the structure of original exhaust pipe, thus structure is simple, and cost is lower.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the front sectional view of embodiments of the invention.
In figure: 10, front pipe; 20, hush pipe, 21, water-cooling tube, 22, Sound-proof material, 23, fixed cover; 30, rear pipe.
Embodiment
Embodiment, as shown in Figure 1: exhaust pipe, comprises hush pipe 20, and to be linked together front pipe 10 and rear pipe 30 by hush pipe 20.In the present invention, this hush pipe 20 outer surface is wound with water-cooling tube 21, and the outside of this water-cooling tube 21 is enclosed with heat resistant type Sound-proof material 22.Certainly, water-cooling tube 21 can utilize the cooling water system of Motor Vehicle.Like this, water-cooling tube 21 reduces the temperature of hush pipe 20 outer surface, thus for using Sound-proof material 22 to provide possibility, and then the erasure effect improving this exhaust pipe that this Sound-proof material 22 is fabulous.
Optimize, the outer cover of this Sound-proof material 22 has the fixed cover 23 of metal.Like this, the fixing of Sound-proof material 22 is convenient to.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
