Problems solved by technology

[0004] However, although the existing muffler has a certain noise reduction effect, the noise reduction effect is not obvious; and the airflow directly impacts the metal casing, causing the metal casing to vibrate greatly, resulting in a large noise caused by the vibration of the metal casing, which affects the motorcycle. overall performance of the car
At the same time, the structure of the existing muffler is relatively complicated, and the volume of the muffler used to achieve the same noise reduction effect is relatively large and the cost is relatively high.

Embodiment 1

[0041] In this embodiment, the noise reduction assembly includes a porous pipe, a noise reduction pipe, a partition 1, a partition 2, a partition 3 and connecting pipes as an example to describe the following.

[0042] The structure schematic diagram of motorcycle muffler in the present embodiment is as figure 1 As shown, the muffler includes an elbow piece 1 , a muffler cylinder 2 , a muffler assembly arranged in the muffler cylinder 2 , a tailpipe 3 and a tail cover 4 which are connected in sequence. Wherein, the muffler assembly includes a clapboard 1 , a clapboard 2 6 , a clapboard 3 7 , a porous pipe 8 with several muffler holes 15 on the pipe wall, a muffler pipe 9 and a connecting pipe 10 . The first partition 5 , the second partition 6 and the third partition 7 divide the muffler cylinder 2 into a first cavity 11 , a second cavity 12 , a third cavity 13 and a fourth cavity 31 in sequence. The porous pipe 8 is inserted on the partition plate 5, and one end thereof is c...

Embodiment 2

[0050] In this embodiment, the noise reduction component includes a porous pipe, a noise reduction pipe, a partition plate 1, a single-hole plate, a three-hole plate, an air guide tube 1 and an air guide tube 2 as an example to describe the following.

[0051] The structure schematic diagram of motorcycle muffler in the present embodiment is as Figure 5 As shown, the muffler includes an elbow piece 1 , a muffler cylinder 2 , a muffler assembly arranged in the muffler cylinder 2 , a tailpipe 3 and a tail cover 4 which are connected in sequence. Among them, the muffler assembly includes a porous pipe 8 with several muffler holes 15 on the pipe wall, a muffler pipe 9, a clapboard 5, a single-hole disc 23, a three-hole disc 24, an air guide tube 25 and an air guide tube 2 26. . The muffler cylinder 2 is divided into the first cavity 11 , the second cavity 12 , the third cavity 13 and the fourth cavity 31 by the first partition 5 , the single-hole plate 23 and the three-hole plat...

Embodiment 3

[0059] The difference between the present embodiment and the first embodiment is that the noise reduction component only includes the porous pipe, the noise reduction pipe and the partition one, and the other structures are consistent with the first embodiment.

[0060] The porous pipe of the muffler in this embodiment is inserted on the first partition, one end of which is connected to one end of the muffler pipe, and the other end is connected to one end of the elbow; the other end of the muffler pipe is provided with a blocking cover to form a blind end; the tail pipe One end is set inside the muffler cylinder, and the other end is the exhaust end, which is set outside the muffler cylinder.

[0061] The working principle of the motorcycle muffler in this embodiment is as follows: the airflow discharged from the motorcycle directly enters the porous pipe from the elbow, and most of the main flow of the airflow enters the muffler pipe through the porous pipe for consumption. ...

Abstract

The invention provides a silencer of a motorcycle. The silencer of the motorcycle is simple in structure and low in cost. The silencer of the motorcycle comprises an elbow piece, a silencer cylinder, a silencing assembly arranged in the silencer cylinder, a tail pipe and a tail cover, wherein the elbow piece, the silencer cylinder, the silencing assembly, the tail pipe and the tail cover are sequentially connected. The silencer of the motorcycle is characterized in that the silencing assembly comprises a first separating board, a perforated pipe and a silencing pipe; the perforated pipe penetrates through the first separating board, one end of the perforated pipe is connected with one end of the silencing pipe, and the other end of the perforated pipe is connected with one end of the elbow piece; the other end of the silencing pipe is provided with a blocking cover, so that a blind end is formed; one end of the tail pipe is arranged in the silencer cylinder and the other end of the tail pipe is an air exhausting end and arranged outside the silencer cylinder. According to the silencer of the motorcycle, energy carried by a pulse air stream is consumed through mutual hedging between air streams, the silencing effect of the silencer is good, the generality is high, and popularization is facilitated.

Description

technical field [0001] The invention relates to a mechanical muffler, more specifically, to a motorcycle muffler. Background technique [0002] With the development of science and technology and the improvement of people's living standards, various motor vehicles are widely used in people's daily life as a common means of transportation, such as the widely used motorcycle. Because the power factors of motorcycles can produce relatively large noises, various mufflers are widely used on motorcycles to achieve the purpose of reducing noise. [0003] A muffler is a device that allows airflow to pass through to attenuate noise, and is one of the important parts on a motorcycle. The performance of the muffler not only affects the noise of the motorcycle, but also has a great influence on the performance of the engine, such as power, fuel consumption, and torque. The muffler principle of the motorcycle muffler is to use the appropriate combination of the cavity and the tube to pr...
