Abstract
The utility model discloses a motorcycle muffler, which is arranged on an exhaust port of a motorcycle exhaust tube, comprising three muffling chambers of a first chamber, a second chamber and a third chamber; wherein, the third chamber is arranged between the first chamber and the second chamber. A plurality of baffles are arranged among the muffling chambers, and a plurality of air vents are arranged on the baffle between the second and the third chambers. The inlet of the first chamber is connected to the exhaust port of the exhausting pipe. The length of the first chamber is one third to a half of the whole muffler length. The first chamber and the second chamber are connected through the vent pipe passing cross the third chamber which is equipped with a vent pipe passing through the second chamber and out of the muffler. Compared with the prior art with the same profile, the utility model has the advantages that the device increases the space of the first chamber, by which the air flow produces a large amount of interference flow in the chambers to reduce the air flow speed, vibration and noise, and the waste gas exhausted from the engine makes fully chemical reaction in the position to reduce the exhausting effectively. The utility model increases the airflow passing area to relieve the noise as possible.
Description
Technical field
The utility model relates to a kind of noise eliminator of motorcycle.
Background technique
The motorcycle baffler is installed in the outlet pipe air outlet to eliminate the noise of motor.The working principle of baffler is to reduce low frequency by sympathetic response and reflection, and the result of this reduction reduces vibration and noise exactly.As shown in Figure 1, general motorcycle baffler is the system of one 2～4 chamber, air-flow is discharged silencing apparatus by the breathing pipe on the dividing plate between each chamber successively, and the flow-disturbing effect by dividing plate reduces flow velocity gradually, vibration and noise that sympathetic response and the reflection by each chamber reduces silencing apparatus.But its erasure effect is not satisfactory.
The model utility content
The utility model technical issues that need to address just are to overcome the defective of existing noise eliminator of motorcycle, and a kind of noise eliminator of motorcycle is provided, its novel structure, and it is effective to eliminate the noise.
For addressing the above problem, the utility model adopts following technological scheme:
The utility model noise eliminator of motorcycle, it is installed in the motorcycle exhaust pipe air outlet, described silencing apparatus comprises a chamber, three noise elimination cavities in two chambeies and three chambeies, be three chambeies between one chamber and two chambeies, be respectively arranged with dividing plate between each noise elimination cavity, be respectively arranged with the hole of the breathing pipe that is welded to connect each noise elimination cavity on the dividing plate, the inlet end in one chamber is connected with the air outlet of outlet pipe, the length in one chamber accounts for the 1/3-1/2 of silencing apparatus total length, breathing pipe between one chamber and two chambeies passes three chambeies and is fixed on and is communicated with a chamber and two chambeies on the dividing plate between a chamber and three chambeies and two chambeies and three chambeies, breathing pipe between two chambeies and three chambeies is fixed on and is communicated with two chambeies and three chambeies on the dividing plate between two chambeies and three chambeies, and three chambeies are provided with the breathing pipe that passes two chambeies and stretch out silencing apparatus.
Outlet pipe described in the utility model is a bimetallic tube, and in order to make full use of the space of outlet pipe, the vestibule between the utility model outlet pipe inner and outer pipe is the silencing apparatus primary barrel, and the interior pipe of outlet pipe is provided with the primary barrel suction port that is connected with primary barrel.
In order to help passing through of air-flow, the air inlet port of breathing pipe described in the utility model is the cone expansion mouth.
Innovative point of the present utility model is:
1, the utility model has increased the space of first chamber under the profile identical with existing silencing apparatus, make air-flow produce a large amount of flow-disturbings on the one hand at this chamber, reduce air-flow velocity, reduce vibration and noise, the waste gas that motor is discharged carries out sufficient chemical reaction, can reduce discharging effectively;
2, the chamber of the utility model silencing apparatus is not to pass through silencing apparatus successively, has increased air communication like this and has crossed area, and pneumatic noise is eliminated as much as possible;
3, in the bimetallic tube of outlet pipe, increased primary barrel, made full use of the space of outlet pipe, this layout can improve the ability that whole system reduces low frequency, and the most direct result reduces noise and level of vibration exactly.
4, the air inlet port of the breathing pipe on each dividing plate has adopted the cone expansion mouth, helps passing through of air-flow.

Embodiment
As shown in Figure 2, the utility model noise eliminator of motorcycle, it is installed in motorcycle exhaust pipe 1 air outlet, described silencing apparatus comprises a chamber 2,4 three noise elimination cavities in two chambeies 3 and three chambeies, be three chambeies between one chamber and two chambeies, be respectively arranged with dividing plate 5-1 between each noise elimination cavity, 5-2, be respectively arranged with the hole of the breathing pipe that is welded to connect each noise elimination cavity on the dividing plate, the inlet end in one chamber is connected with the air outlet of outlet pipe, the length in one chamber accounts for the 1/3-1/2 of silencing apparatus total length, breathing pipe 6-1 between one chamber and two chambeies passes three chambeies and is fixed on the dividing plate between a chamber and three chambeies and two chambeies and three chambeies, breathing pipe 6-2 between two chambeies and three chambeies is fixed on the dividing plate between two chambeies and three chambeies, and three chambeies are provided with the breathing pipe 6-3 that passes two chambeies and stretch out silencing apparatus.
As shown in Figure 3, outlet pipe described in the utility model is a bimetallic tube, in order to make full use of the space of outlet pipe, the vestibule between the utility model outlet pipe inner and outer pipe is a silencing apparatus primary barrel 7, and the interior pipe of outlet pipe is provided with the primary barrel suction port 8 that is connected with primary barrel.
In order to help passing through of air-flow, the air inlet port of breathing pipe described in the utility model is the cone expansion mouth.
The utility model is not limited to above-mentioned preferred forms, and other any identical with the utility model or akin products that anyone draws under enlightenment of the present utility model all drop within the protection domain of the present utility model.
