Abstract
The utility model embodiment discloses a kind of double tail pipe silencing apparatus, divide the distribution of upper and lower double shell balanced, symmetrical, be separated out 3 noise reduction cavitys in every bar cylindrical shell, air-flow is vented by the netted air outlet hole in 3 cavitys, after motor discharge air-flow leads to silencing apparatus first cavity, second netted air outlet hole of cavity is flow into by netted air outlet hole, again by the 3rd the netted air outlet hole of cavity, often through a cavity, air-flow all changes, from large to small, thus reach erasure effect; Adopt netted shunting mode of giving vent to anger, make discharge air-flow by focus on shunting, again concentrate shunt again, finally concentrate and discharge cylindrical shell, silencing apparatus sound set is made to synthesize powerful explosive force sound, the present embodiment solves the method reducing silencing apparatus noise, change loopback sound-deadening and noise-reducing sound method in air flow collection, effectively reduce noise, promote the explosive force of motorcycle engine.
Description
Technical field
The utility model relates to silencing apparatus field, particularly relates to a kind of double tail pipe silencing apparatus.
Background technique
Silencing apparatus, is mainly configured on motorcycle and plays elimination engine sound effect, and in existing silencing apparatus, hush pipe air outlet hole order number is many, and hole is less than normal, and during exhaust, sound is larger.
Model utility content
The utility model embodiment technical problem to be solved is, provide that a kind of durable, explosive force is strong, environmental protection, good heat dissipation effect double tail pipe silencing apparatus.
Described double tail pipe silencing apparatus, comprise upper and lower distribution two cylindrical shells, one end of described cylindrical shell is connected with car body exhaust port respectively, the other end is exit orifice, multiple noise reduction cavity is arranged at intervals with in described each cylindrical shell, adjacent two noise reduction cavity joints are provided with air outlet hole, and described air outlet hole is netted air outlet hole.
As the further improvement of the technical program, in described each cylindrical shell, be arranged at intervals with three noise reduction cavitys.
Described netted air outlet hole is the cylindrical cavity along cylindrical shell radial projection, and described cylindrical cavity is provided with the netted hole for being vented on the surface.
Implement the utility model embodiment, there is following beneficial effect:
The double tail pipe silencing apparatus of the utility model embodiment, divide the distribution of upper and lower double shell balanced, symmetrical, in every bar cylindrical shell, be separated out 3 noise reduction cavitys, air-flow is by the netted air outlet hole exhaust in 3 cavitys, after motor discharge air-flow leads to silencing apparatus first cavity, flow into second netted air outlet hole of cavity by netted air outlet hole, then by the 3rd the netted air outlet hole of cavity, often through a cavity, air-flow all changes, and from large to small, thus reaches erasure effect; Adopt netted shunting mode of giving vent to anger, make discharge air-flow by focus on shunting, again concentrate shunt again, finally concentrate and discharge cylindrical shell, silencing apparatus sound set is made to synthesize powerful explosive force sound, the present embodiment solves the method reducing silencing apparatus noise, change loopback sound-deadening and noise-reducing sound method in air flow collection, effectively reduce noise, promote the explosive force of motorcycle engine.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
The double tail pipe silencing apparatus of the utility model embodiment, comprise upper and lower distribution two cylindrical shells 1, one end of cylindrical shell 1 is connected with car body exhaust port 2 respectively, the other end is exit orifice 3, three noise reduction cavitys 5 are arranged at intervals with in each cylindrical shell, adjacent two noise reduction cavity joints are provided with netted air outlet hole 4, and netted air outlet hole is the cylindrical cavity along cylindrical shell radial projection, and described cylindrical cavity is provided with the netted hole for being vented on the surface.
The double tail pipe silencing apparatus of the utility model embodiment, divide the distribution of upper and lower double shell balanced, symmetrical, in every bar cylindrical shell, be separated out 3 noise reduction cavitys, air-flow is by the netted air outlet hole exhaust in 3 cavitys, after motor discharge air-flow leads to silencing apparatus first cavity 6, flow into second netted air outlet hole of cavity 7 by netted air outlet hole, then by the 3rd cavity net 8 shape air outlet hole, often through a cavity, air-flow all changes, and from large to small, thus reaches erasure effect; Adopt netted shunting mode of giving vent to anger, make discharge air-flow by focus on shunting, again concentrate shunt again, finally concentrate and discharge cylindrical shell, silencing apparatus sound set is made to synthesize powerful explosive force sound, the present embodiment solves the method reducing silencing apparatus noise, change loopback sound-deadening and noise-reducing sound method in air flow collection, effectively reduce noise, promote the explosive force of motorcycle engine.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
