Damper used for noise silencer of the present utility model, comprises car body connecting plate, silencer anchor ear and suspension arm, alsoComprise the upper coupling assembling that suspension arm upper end is fixed on to the vertical side plate of car body connecting plate, described upper coupling assemblingArrange at least one group, coupling assembling includes upper connector and is arranged at the vertical of described car body connecting plate on every groupThe first damping body passing for vibration damping and by upper connector between side plate and suspension arm.
Further, upper coupling assembling also comprises vertical side plate suspension arm one side far away that is arranged on described car body connecting plateAnd form the second fastening damping body by described upper connector.
Further, suspension arm upper end face convexes to form the positioning boss being useful on the first damping body location.
Further, under also comprising described in lower connector for connecting suspension arm lower end and silencer anchor ear and overcoatConnector is for the vibration damping bush of vibration damping, and two both sides, engaging lug apportion suspension arm lower end of described silencer anchor ear alsoForm fasteningly by described lower connector, between two engaging lugs of described silencer anchor ear and suspension arm, be provided with oneFor the vibration isolator of vibration isolation.
Further, the one-body molded location being formed with for the engaging lug location to silencer anchor ear, suspension arm lower endPlate, location-plate and suspension arm body form decussate texture.
Further, vibration damping bush is made up of the lining body of two split settings, and each lining body is T word cover, lining bodyEnd flange is close to the lateral surface setting of corresponding engaging lug under the coupling mechanism force of lower connector.
The beneficial effects of the utility model: damper used for noise silencer of the present utility model, simple in structure, installation sideJust, the vertical side plate of car body connecting plate is connected by upper connector with suspension arm upper end, and by the first damping bodyForm vibration isolation effect, suspension arm is contacted completely and kept apart with the rigidity of car body connecting plate, thus capable to vehicleCross the vibration of transmitting from car body in journey and effectively isolate, reduce the vibration of silencer as far as possible, and vibration dampingBody has stronger fatigue resistance, can improve the service life of silencer.
