Problems solved by technology

[0005] According to the above, most of the motorcycle exhaust pipes used on the market today are iron pipes. Since the waste displacement of a single motorcycle engine is too large during use, conventional noise reduction exhaust pipes will add multiple layers of exhaust pipes in its inner cavity. Silencer, but as we all know, the speed of the motorcycle is related to the exhaust gas emission from the exhaust pipe. Because the waste contains an oil layer that is not fully burned, and the engine oil leaks due to engine problems, it will cause excessive carbon deposits in the inner cavity of the exhaust pipe. , which will cause the internal blockage of the exhaust pipe, which will cause the problem of engine power drop
[0006] Existing motorcycle exhaust pipes need to be replaced as a whole once there is too much internal carbon deposition in use, which often results in waste of preparing exhaust pipe titanium alloys. Therefore, how to improve the efficient utilization of motorcycle exhaust pipes is an important aspect of the present invention. Technical difficulties that people need to solve

Embodiment 1

[0055] combine Figure 4 , 5 , 8, 10 and 11, the motorcycle exhaust pipe muffler provided by the present invention includes a connecting mechanism 100, an exhaust gas displacement control mechanism 200, a noise reduction combination 300, a water circulation heat dissipation combination 400 and an assembled tail end mechanism 500, wherein the exhaust gas The displacement control mechanism 200 is fixedly installed on the connection mechanism 100, and the noise reduction combination 300 can be assembled on the exhaust gas displacement control mechanism 200. In addition, the water circulation heat dissipation combination 400 is installed outside the noise reduction combination 300 for the discharge of heat in the exhaust gas. The tail end mechanism 500 is installed on the sound-absorbing combination 300 .

[0056] The connecting mechanism 100 includes an arc pipe 110, a terminal head 120 and a tapered pipe 130, wherein the exhaust gas displacement control mechanism 200 includes a...

Embodiment 2

[0059] combine Figure 4 As shown, in the above embodiment, the connecting mechanism 100 includes an arc tube 110 , an end 120 welded on the arc tube 110 , and a tapered tube 130 installed at one end of the arc tube 110 .

[0060] By adopting the above-mentioned technical scheme, according to the use of motorcycle exhaust pipes today, a trapezoidal tapered pipe 130 is fixedly welded at one end of the arc pipe 110, and a trapezoidal pipe 130 is formed between the tapered pipe 130 and the inner cavity of the safety outer cylinder 210. The large volume space can make the exhaust gas generate enough negative pressure after entering the space, and can facilitate the rapid exchange of airflow during engine operation.

Embodiment 3

[0062] combine Figure 5 As shown, in the above embodiment, the fine-tuning part includes a screw rod 240 threadedly connected to the inner core ring 230, a soft screw rod 250 movable in the annular groove in the middle of the inner core ring 230, and teeth engaging with the soft screw rod 250. Article 260.

[0063] By adopting the above-mentioned technical solution, by penetrating the top ends of the two screw rods 240 to the outside of the safety outer cylinder 210, when the device is adapted to different types of engines, in order to quickly adjust the exhaust diameter of the internal cavity of the device on the exhaust gas load Therefore, the fan-shaped baffles are movably installed inside the inner core ring 230, and the diameter of the circular notch inside the inner core ring 230 for exhaust gas discharge is controlled by fine-tuning the two screw rods 240, thereby improving the performance of the device on different Model suitability.

Abstract

The invention discloses a muffler for a motorcycle exhaust pipe and its assembly, including a connecting mechanism, a waste gas displacement control mechanism, a sound-absorbing combination, a water circulation heat dissipation combination and an assembled tail end mechanism. The connecting mechanism has a built-in cavity, and the exhaust gas discharge The volume control mechanism includes a fine-tuning part and an exhaust part, and the exhaust part includes a safety outer cylinder, an inner core ring welded in the middle of the inner cavity of the safety outer cylinder, and an anti-seepage pad installed outside the safety outer cylinder, The sound-absorbing combination includes a jacket and an output pipe located in the middle of the jacket. By opening an inwardly recessed annular notch on the inner side of the outer end of the jacket, at this time, insert the external port on the inner side of the ring, and use the fixing piece to fix the jacket and the external port, and use the ring at the inner end of the cooling member to The protrusion pair interferes with the fixation of the inner cylinder, so that the exhaust pipe can be quickly disassembled, thereby solving the problem that the exhaust pipe is difficult to disassemble today.

Description

technical field [0001] The invention relates to the field of motorcycle exhaust pipes, in particular to a muffler for motorcycle exhaust pipes. Background technique [0002] The motorcycle exhaust pipe is a part of the motorcycle exhaust system. The exhaust system is connected to the exhaust port of the engine combustion chamber, through the exhaust manifold, the middle section of the exhaust pipe to the end of the exhaust pipe. The role of the exhaust pipe on the vehicle The reason is that it discharges the high-temperature exhaust gas after combustion to the rear or side of the vehicle to reduce the impact of the exhaust gas on the driver. Secondly, it uses its internal muffler to reduce the noise generated during the high-temperature and high-pressure exhaust gas discharge to an acceptable level. limit. [0003] With reference to publication number: muffler and motorcycle thereof shown in CN107605571A. [0004] With reference to publication number: a kind of motorcycle ...
