Gas exhaust tube noise reduction device for motorcycle

Abstract

The invention discloses an exhaust pipe noise reduction device for motorcycles, comprising a fixing device, one side of the fixing device is fixedly connected with an exhaust pipe, and the other side of the fixing device is fixedly connected with a connecting sleeve, the The side of the connecting sleeve away from the fixing device is fixedly connected with a first noise reduction chamber, and a first air guide pipe is arranged inside the first noise reduction chamber, and one end of the first air guide pipe is fixedly connected to the exhaust tube. Inside, the other end of the first air duct is fixedly connected with a second air duct, and the second air duct is arranged inside the second noise reduction chamber. The exhaust pipe noise reduction device for motorcycles, by setting multi-stage air guide pipes, can buffer or disperse the speed of exhaust gas, so that the speed of exhaust gas when discharged from the exhaust pipe to the air is reduced; multi-stage sound-absorbing layers are provided , to further buffer or disperse the velocity of the exhaust gas, so that the impact force of the low-speed exhaust gas entering the air is reduced, thereby achieving the purpose of noise reduction.

Description

technical field [0001] The invention relates to the technical field of motorcycle noise reduction, in particular to an exhaust pipe noise reduction device for motorcycles. Background technique [0002] Motorcycle is a very common means of transportation, and the exhaust pipe is an important part of the motorcycle. When the existing motorcycle is running, the exhaust pipe will generate a lot of noise, which will cause low driving comfort and produce Noise pollution, so the motorcycle noise reduction and noise reduction device came into operation. The motorcycle noise reducer is a device that allows airflow to pass through and attenuates noise. [0003] Exhaust tubes of existing motorcycle engines are provided with a damping tube in the outer tube, and a tailpipe is connected to the end of the outer tube. Through the cooperation of the damping tube and the outer tube, the noise generated when the engine exhaust is discharged can be appropriately weakened, but the engine The h...
