Engine muffling component vibration attenuation mounting device

Abstract

The invention discloses an engine muffling component vibration attenuation mounting device which comprises a car body connecting plate, a muffler hoop and a suspension arm, and further comprises an upper connecting component for fixing the upper end of the suspension arm to a vertical side plate of the car body connecting plate, wherein the number of the upper connecting component is at least one; each upper connecting component comprises an upper connecting piece, and a first vibration attenuation body which is arranged between the vertical side plate of the car body connecting plate and the suspension arm, is used for vibration attenuation and penetrates through the upper connecting piece. The engine muffling component vibration attenuation mounting device is simple in structure and convenient to mount; the vertical side plate of the car body connecting plate is connected with the upper end of the suspension arm through the upper connecting pieces, and a vibration isolation effect is exerted through the first vibration attenuation bodies, so that rigid contact between the suspension arm and the car body connecting plate is isolated completely, the vibration from a car body when a car runs is isolated effectively, and the vibration of a muffler is reduced to the greatest extent; and the vibration attenuation bodies have higher fatigue resistance, so that the service life of the muffler can be increased.

Description

technical field

[0001] The invention relates to the field of auto parts, in particular to a vibration damping installation device for an engine noise reduction component. Background technique

[0002] Automobile muffler, also known as exhaust muffler, is a component installed at the end of the exhaust pipe of the automobile. Its function is to reduce the speed and pressure of exhaust gas discharged from the engine to reduce noise.

[0003] At present, the automobile muffler is generally assembled with a hook and a rubber hanger. The hook is generally made of ordinary steel, and one end of the hook is extruded into a pier head, which is connected and assembled with the rubber hanger. Although this structure is simple in process, there are the following problems after assembly: the posture of the rubber suspension cannot be adjusted, the rubber suspension is twisted and deformed, and the muffler will generate certain vibrations with the driving of the car, which will cause the...
