Between in shuttle, utilize the continuous change of divergence ratio, suppress Low Medium Frequency noise.Front end-plate depression is respectively equipped with front and rear end plate
Buffering is played a part of in area and end plate depressed area, front end-plate depressed area and end plate depressed area, further suppresses noise.
Preferably, be equipped with described front end-plate and dividing plate mutually corresponding to air inlet pipe mounting hole, air inlet pipe pass through into
Tracheae mounting hole；Described dividing plate is provided with mutually corresponding breather pipe mounting hole, and breather pipe passes through breather pipe mounting hole；It is described
Dividing plate and end plate on be equipped with blast pipe mounting hole, blast pipe passes through blast pipe mounting hole.
Preferably, every piece of dividing plate and end plate are provided with two blast pipe mounting holes, corresponding described automobile row
Gas-pipe muffler is provided with two blast pipes.
Preferably, the sectional dimension of the rear and front end of described muffler shell is gradually reduced.Different space sizes have
Help eliminate the sound wave of different frequency.
Using technical scheme provided by the utility model, compared with prior art, have the advantages that：
When suppressing the noise of vehicle exhaust using the utility model, air-flow constantly shuttles by dividing plate, air inlet pipe, escape pipe
With the micropore on breather pipe, noise is reduced using the continuous change of divergence ratio；And before being respectively equipped with front end-plate and end plate
End plate depressed area and end plate depression, front end-plate depressed area and end plate depression enter row buffering to air-flow, and increase reduces noise
Effect；Muffler shell uses the structure type that rear and front end size is gradually reduced, and is advantageous to eliminate the sound wave of different frequency.
