Masses road view is the SUV model with popular nowadays, road watchs a space capacious, motive force is powerful, omnibus price is more compact than home model the count as one of the best in SUV market, be like person meaning very much however on the processing of certain details nevertheless, especially sound insulation processing, a lot of cars advocate reflective road watchs noise very big, how that should solve noise problem?
In watching process of Che Youliao day with masses road understanding arrives, the car that the end of the year shifted last year, which embryo a confusion of voices calls then big, open the concrete route, monarch that listens to tire to give out especially, engine also is unusual noise, do not know how to do all the time, never also have in the heart change one's costume or dress soundproof concept, ran to wade with the friend after high speed, discovering wind a confusion of voices also is to be raided in succession, bear hard. Also get cicada to change one's costume or dress from inside the friend's mouth sound insulation can solve this problem, the home was not answered lose the car to beautiful to close consummate music to change one's costume or dress directly inn, undertake sound insulation changes his costume or dress.
Next my door sees beautiful close masses road to watch the solution of car friend.
Sound insulation uses industry position: Lid of chassis, mothball box, engine, cistern, 4 the door, four-wheel sound insulation.
Will see the sound insulation construction that sees door plank position first, lining of primary vehicle door plank is very pallet, make step of what sound insulation hardly, as a result of the characteristic of structure of car door plank, when drive a vehicle, once speed accelerates noise of wind a confusion of voices, air,can pass a crack between a door and its frame to pass into railroad car inside. Because this uses sound insulation of become known shark to stop first,shake glue did ground floor to car door plank stop brace up processing, did the 2nd sealed processing to its again next, to make sound insulation effect more outstanding, shark of reuse become known is sound-absorbing cotton makes three-layer construction on lid of door plank act the role ofing.
The engine of the front that sees a car again then covers a part, the resonance noise that the noise of this part includes engine to build and the noise that engine work produces, and the lacquer face that the quantity of heat in the generation in working process still meets engine be built to engine is formed roast, so silver-colored shark of shark of use become known is opposite first engine lid did the car to stop brace up processing, used adiabatic film to do the 2nd sealed processing again next, reducing noise while still cut off what quantity of heat covers lacquer range to engine is roast.
Cistern is engine and car are indoor have a common boundary also is engine noise is passed into indoor " bridge " , so cistern is sound insulation falls the significant position of a confusion of voices.
The car is in the process of travel, chassis and end box can produce resonance already, at the same time fetal a confusion of voices, road a confusion of voices is passed into very easily also come in, because this changes this costume or dress,the sound insulation that deadening did double deck to the batholith of the car and mothball box handles shark of technician use become known. This reduced all sorts of noise of chassis generation not only, return effective buildup at the same time the tigidity of Ban gold.
Tire is a place that the car contacts exclusively with the ground, all sorts of noise can produce in process of drive a vehicle (for example: Cobble knock iron piece and attrition of generation of ground of contact of leaf board, tire waits noise a moment) pass into indoor, so fetal a confusion of voices also is cannot of oversight.
