Description

Resonator adhesion vehicle wheel

The present invention relates to a wheel for a vehicle with a resonator, and more particularly, to a wheel for a vehicle with a resonator with a resonator for reducing vibration and noise generated by air pressure in a tire when driving.

In general, an automobile tire has an inner circumferential surface coupled to a rim formed on a vehicle wheel to fill air to elastically support the vehicle. Tires mounted on the vehicle generate noise due to constant friction with the road surface while driving.

In particular, there are low frequency noises caused by compression and expansion of internal air due to the shape deformation of the tire due to tire and road surface contact, and high frequency noise caused by air or surface friction between the tread and the road surface.

These noises are reflected between the inner surface of the tire and the rim, causing resonance, and transmitted inside the vehicle, making the driver feel noise.

Korean Patent Publication No. 10-2008-0038312 (Publication No.) discloses a technique in which a fabric layer is attached to a rim so as to expand by heat generated from a tire as a vehicle travels to serve as a hollow chamber. However, this is a high sound absorbing effect, but due to the durability of the fabric layer is easily removed from the tire there is a disadvantage that does not effectively reduce the resonance.

In addition, there are technologies in which a resonator is formed on the rim of a vehicle wheel, but there is a problem in that the manufacturing time is long and the cost is increased because an additional process (for example, a welding process of a disc and a rim) is required when forming the resonator. . In addition, there is a problem that can lead to a car accident when a defect occurs in the weld.

In order to solve the above problems, the present invention is to provide a resonator-equipped vehicle wheel with a resonator for the reduction of vibration and noise generated by the air pressure inside the tire when driving.

In order to solve the above problems, the wheel for a vehicle with a resonator according to the first embodiment of the present invention, in the wheel for the car with a resonator attached to the rim, the rim is formed to protrude to the middle surface of the rim, And a locking portion spaced apart by a predetermined interval in the width direction of the middle surface portion, wherein the resonator has a space formed therein and is formed to have a length in the circumferential direction of the rim, and is mounted between the locking portions so that an outer circumferential surface of the middle surface portion is provided. A resonance tube installed to be in close contact with; It is possible to provide a resonator vehicle wheel including a resonance tube cover is formed to cover the resonance tube and is fixed to the engaging portion.

In addition, the engaging portion is formed to protrude in a 'b' shape, is formed symmetrically with respect to the center of the spaced interval, characterized in that formed in the same length as the length of the resonance tube in the circumferential direction of the rim.

In addition, the resonance tube may include a locking groove formed on both sides of the lower end of the resonance tube so that the locking portion is received from the lower side.

In addition, the resonance tube cover is formed to correspond to the shape of the resonance tube so that the bottom surface is open and the resonance tube, the cover is formed to be separated based on the width direction center of the resonance tube; Fixing protrusions are formed to protrude inward on both sides of the lower end of the cover is fixed to the engaging portion; Two coupling plates each formed on both sides with respect to the center separated from the upper end of the cover and installed to be engaged with each other; It may include a coupling hole formed to penetrate the two coupling plates and a coupling bolt inserted into the coupling hole to fix the two coupling plates.

In addition, the resonance tube cover is characterized in that the fixing projection is inserted into the locking portion from the outside of the locking portion is in contact with the lower surface of the locking portion and the upper surface of the fixing projection and the locking portion is accommodated inside the resonance tube cover.

In addition, the resonance tube cover of the wheel for a vehicle with a resonator according to the second embodiment of the present invention is formed to correspond to the shape of the resonance tube so that the lower surface is open and cover the resonance tube, to be separated based on the width direction center of the resonance tube A cover including a first cover and a second cover formed; Fixing protrusions are formed to protrude inward on both sides of the lower end of the cover is fixed to the engaging portion; First and second coupling plates respectively formed on upper ends of the first cover and the second cover to be engaged with each other; A coupling hole formed to penetrate the first and second coupling plates and a coupling bolt inserted into the coupling hole to fix the first and second coupling plates, wherein the first coupling plate has a length in the first cover.
