Problems solved by technology
The existing traditional methods for reducing tire noise have several defects, and cannot shield the noise generated by the wheels and the ground during the whole process of vehicle movement
In particular, those methods do not effectively absorb the energy associated with the shock waves that generate tire noise
While tires generate considerable energy, an effective tire noise absorber should reduce the noise generated by this energy, however, conventional methods do not adequately reduce this noise

The invention discloses a wheel acoustic hood. The wheel acoustic hood comprises a supporting rod, suckers, pull springs, square screw rods, first check nuts, second check nuts, adapter bearing components, acoustic hood component connecting pieces, acoustic hood components and bolt components; and the acoustic hood components comprise rubber blocks, side plates, hinges, left acoustic hoods, acoustic hood screws, right acoustic hoods, steering fixing screws, steering lugs, rotating shafts and so on. The wheel acoustic hood can shield noises generated by wheels and the ground in the whole automobile running process so that measurements of noises of other automobile body parts can be guaranteed and the wheel acoustic hood can adapt to passenger vehicle models with different wheel diameters, wherein the front wheel acoustic hood can move together with the tire, the rear wheel acoustic hood substantially does translation along with the automobile body and can effectively suppress side-to-side shaking generated by the whole acoustic hood in the automobile running process; and the wheel acoustic hood has the advantages of convenient assembling and disassembling, wide application range and strong operability.
Description
technical field [0001] The invention relates to a sound insulation cover, in particular to a wheel sound insulation cover. Background technique [0002] Car noise test is a test that must be done in the automotive industry. During the noise test, the movement between the car tires and the ground will generate noise. noise. The existing traditional methods for reducing tire noise have several defects, and cannot shield the noise generated by the wheels and the ground during the whole process of vehicle movement. In particular, those methods do not effectively absorb the energy associated with the shock waves that generate tire noise. While tires generate considerable energy, an effective tire noise absorber should reduce the noise generated by this energy, however, conventional methods do not adequately reduce the noise. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wheel sound insulation cover, which can s...
