Abstract
The utility model relates to a vehicle noise elimination system and vehicle. The vehicle noise elimination system comprises a post-silencer, a pre-silencer, an elbow pipe and a lifting hook, wherein one end of the elbow pipe is connected with the post-silencer, the other end of the elbow pipe is connected with the pre-silencer, and the elbow pipe is supported by the lifting hook. The lifting hook comprises an installation portion which is connected with a vehicle body and a support portion which is connected with the elbow pipe. The support portion is in the shape of a concave arc. The bottom of the elbow pipe is connected with the inner edge of the concave-arc shape. The vehicle noise elimination system not only enhances the connection intensity between the lifting hook and the elbow pipe, but also supports the elbow so as to reduce the vibration of an exhaust pipe of the post-silencer which is connected with the elbow, thereby extending the service life of the exhaust pipe of the post-silencer.
Description
Technical field
The utility model relates to vehicular field, is specifically related to a kind of vehicle sound-attenuating system and is provided with the vehicle of this vehicle sound-attenuating system.
Background technique
Generally all can be provided with sound-attenuating system on the engine exhaust system of automobile, to reduce the noise of vent systems.Fig. 1 and Fig. 2 show the sound-attenuating system in the correlation technique, the bend pipe 13 that it comprises rear class silencing apparatus 11, prime silencing apparatus 12 and connects rear class silencing apparatus 11 and prime silencing apparatus 12.Bend pipe 13 is fixed on the vehicle body by suspension hook 14.Suspension hook 14 comprises the first joint 141 and the second joint 142.The first joint 141 is connected with vehicle body, and the second joint 142 is cylindrical, is welded on the side of bend pipe 13.But, because the second joint 142 is the sides that are welded on bend pipe 13 with form of straight lines, thus its structural strength a little less than.Therefore, when Vehicle Driving Cycle, owing to reasons such as road bump and engine luggines, cause easily the outlet pipe of rear class silencing apparatus 11 to suffer larger vibration, directly have influence on the durability of the outlet pipe of rear class silencing apparatus 11, thereby affect Security and the working life of car load.
The model utility content
In view of this, the utility model aim to provide that a kind of intensity is high, the vehicle sound-attenuating system of long service life and be provided with the vehicle of this vehicle sound-attenuating system.
On the one hand, the utility model provides a kind of vehicle sound-attenuating system, comprising: the rear class silencing apparatus; The prime silencing apparatus; Bend pipe, the one end connects the rear class silencing apparatus, and the other end connects the prime silencing apparatus; And the suspension hook of the described bend pipe of support, described suspension hook comprises the assembly department that is connected with vehicle body and the supporting portion that is connected with described bend pipe, and described supporting portion is lower concave arc shape, and the bottom of described bend pipe is connected to the interior edge of described lower concave arc shape.
Preferably, described supporting portion is circular arc, and fits with the bottom of described bend pipe.
Preferably, the corresponding central angle of described circular arc is less than 180 degree.
Preferably, the bottom welding of described bend pipe is on described supporting portion.
Preferably, described assembly department is cylindrical, and is connected with hanging of vehicle body.
Preferably, described vehicle sound-attenuating system comprises two described rear class silencing apparatuss, and the suction tude of described two rear class silencing apparatuss all is communicated with described bend pipe.
Preferably, the suction tude of described two rear class silencing apparatuss is communicated with described bend pipe by tee union.
The utility model has not only strengthened the join strength of suspension hook and bend pipe, and bend pipe is also formed supporting effect, can reduce the vibration of the outlet pipe of the rear class silencing apparatus that is connected with bend pipe, thereby improves the working life of the outlet pipe of rear class silencing apparatus.
On the other hand, the utility model also provides a kind of vehicle, is provided with above-mentioned each described vehicle sound-attenuating system on the described vehicle.This vehicle obviously also has the technique effect that above-mentioned vehicle sound-attenuating system brings.
