Abstract

The invention belongs to the technical field of exhaust pipes, and particularly relates to an automobile exhaust pipe suspension damping device which comprises a first rubber shell, a second rubber shell, a fixing base, a hoop, a fastening sealing piece, a hoisting damping component and rubber sealing rings. The rubber sealing rings and the first rubber shell are driven by the vibrating silencer to vibrate together, so that the rubber sealing rings slightly move in a staggered mode, and meanwhile, the first rubber shell elastically deforms, so that flexible connection between the silencer andthe exhaust pipe is achieved while automobile exhaust is guaranteed, and meanwhile, the flexible joint between the silencer and the exhaust pipe is sealed through the first rubber shell and the secondrubber shell; flexible connection between the silencer and an automobile chassis is achieved by arranging a hoisting shock absorption part, and buffering and shock absorption are conducted on the vibrating silencer, so that vibration of the silencer is prevented from being transmitted to the vehicle body to generate resonance, noise generated by automobile exhaust is reduced, and then riding comfort is improved.

Description

technical field [0001] The invention belongs to the technical field of exhaust pipes, in particular to a suspension and damping device for automobile exhaust pipes. Background technique [0002] The exhaust pipe is installed between the engine exhaust manifold and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, facilitating installation and prolonging the life of the exhaust muffler system. For ordinary cars, because the exhaust gas of the car is under great pressure when it leaves the engine, the noise it produces may make people feel crazy. At this time, the main role of noise reduction is the exhaust pipe of the car. The device greatly reduces the noise of the car. [0003] The flexible connection in the existing automobile exhaust muffler system is mainly used for shock absorption and buffering the vibration transmitted from the engine, thereby preventing the engine vibration from resonating with the vehicle bo...
