Abstract
The utility model relates to a noise insulation of turbosupercharged engine shock attenuation belt pulley lacks the problem of control driving source vibration noise in order to solve current vehicle to engine NVH, include and expose the sound -proof housing body that some cooperations have the accommodation space, characterized by with the shock attenuation belt pulley sound -proof housing body accommodation space inboard be equipped with the soundproof cotton layer, the sound -proof housing body still is equipped with the fixing base of being connected with turbosupercharged engine, be equipped with in the fixing base with connecting bolt complex bush, bush and sound -proof housing are equipped with the rubber packing ring between physically. Have lockingly move, the installation fixing base of reliable and stable, vibration isolation function, overall structure intensity is high, inhales the sound and gives sound insulation obviously, the cost of manufacture is low, the practicality is strong.
Description
Technical field
The utility model relates to automobile component technology, especially a kind of sound arrester of turbosupercharged engine damper pulley.
Background technique
Car comfort is the major criterion embodying vehicle mass, and noise, vibration and sound vibration roughness are the composite targets weighing automobile making quality, and it is the most direct and most surface to the impression of user vehicle.The NVH problem of vehicle is one of problem of international automobile Ye Ge great car load manufacturing enterprise and parts enterprises concern; Even car load about has the failure problems of 1/3 to be have relation with the NVH problem of vehicle.Pass-by noise controls relevant environmental protection rule and standard also increasingly stringent.The research of NVH characteristic is not only applicable to the development process of whole automobile new product, and is applicable to the research improving existing vehicle riding comfort.This is that a some system for automobile or assembly carry out modeling analysis, find out the factor that riding comfort is had the greatest impact, improve riding comfort by improving excitation source vibration state (range of decrease or shift frequency) or controlling excitation source vibration noise to the transmission of car indoor.At present, NVH problem has become one of subject matter paid close attention in automobile development process Zhong Ge great car load enterprise and parts enterprises, domestic present actual conditions also just pay close attention to the aspect such as Security, fuel economy of vehicle, and to the NVH of context engine do less, indivedual automobile did design to motor in damper pulley, and this sound-insulating cover scheme is less to the noise generated elimination of radiation near crankshaft front end damper pulley, and device is comparatively large, and cost is higher.
Summary of the invention
The purpose of this utility model motor NVH is lacked to the problem controlling excitation source vibration noise to solve existing vehicle, provides a kind of reasonable in design, soundproof effect obviously, the sound arrester of the turbosupercharged engine damper pulley of low cost.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of sound arrester of turbosupercharged engine damper pulley, comprise the sound insulation cover body coordinating with damper pulley exposed parts and there is containing space, it is characterized in that being provided with Sound-proof material layer inside described sound insulation cover body containing space, sound insulation cover body is also provided with the fixed base be connected with turbosupercharged engine, be provided with the lining coordinated with connecting bolt in fixed base, between lining and sound insulation cover body, be provided with rubber washer.The technical program is optimized design for two themes: one, damper pulley---for reducing the impact shock because producing during engine combustion, mainly reduce crankshaft torsional vibrations, be accessory system transferring power, rotary inertia is provided, stored energy, increases mechanical work loss; Two, belt is driven---the power that bent axle exports is passed to air condition compressor, water pump, generator etc. by damper pulley.This case carries out sound arrester design to damper pulley, Sound-proof material is studded with inside cover body, and by being provided with lining, the fixed base of shockproof shock-absorbing measure of rubber washer is arranged on timing chain cover, the noise produced due to radiation near crankshaft front end damper pulley in engine running work is carried out effectively every sound-absorbing.
As preferably, the outer surface of described sound insulation cover body is provided with loose sound grid.Increase sound-absorbing and fall apart audio really, strengthen cover body self structure intensity.
As preferably, described lining is T-shaped cover, and intermediate throughholes coordinates with connecting bolt, lining cylindrical shell external diameter and rubber washer internal diameter interference fit.T-type structure major diameter one end of lining as the pad function of attachment screw, and protects rubber washer not to be damaged.
As preferably, the barrel lenght of described lining is less than the thickness of rubber washer.Be conducive to the fastening of attachment screw, sound insulation cover body is contacted with the mating face seal between timing chain cover.
As preferably, the containing space of the described sound insulation cover body respectively face of wrapping up is curved surface.Take damper pulley as parcel object, leave and drive belt breach, curved-surface structure not only makes cover body structural strength increase, and also makes cover body compact appearance light and handy.
As preferably, described Sound-proof material layer thickness is 1 ~ 10mm.Best Sound-proof material layer thickness is selected according to product specification.
Effective effect of the present utility model is: have mounting-fixing base that is anti-loosening, reliable and stable, vibration isolation function, overall construction intensity is high, and sound-absorbing sound insulation is obvious, and fabricating cost is low, practical.
