Description
Technical field
The present invention relates to tire arts, are a kind of Tire noise reducing flow spoiler in detail.
Background technology
It is well known that tire cavity resonance, i.e. cavity noise, between resonant frequency about 200 ~ 250Hz.Tire internal cavity
Gas is one of the factor for generating tire standing wave, and tire standing wave can interact with wheel rim, and vibrational energy is made to pass through suspension system
System is transferred in driver's cabin in the form of a sound wave, and cavity noise has become the importance of optimization tire/vehicle drive performance.
The main reason for tyre cavity bulk noise generates is that the basic friction angle of the cavity of axial symmetry tire experienced single wave
It is long, minimum and maximum pressure point is respectively present in tire opposite location, nodel line is between minimum and maximum pressure point.When
When tire carrying rolls, ground connection mark causes gas in cavity to disturb, and causes cavity noise.
Part tiremaker reduces tyre cavity bulk noise by the method for being bonded sound-absorbing material in tire tread inner surface,
Although this method can effectively absorb tire cavity resonance sound, it is the increase in Tire production cost, and complete tire
The waste of material is caused after service life.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of Tire noise reducing flow spoiler, can change tire cavity
Interior air column mode solves to cause the resonance of vehicle suspension system because of the vibration of tire cavity, increase comfort by bus with it is mute
Property；Do not increase Tire production cost simultaneously, and reusable, is suitable for same specification all tire.
The technical solution adopted by the present invention to solve the technical problems is：A kind of Tire noise reducing flow spoiler is equipped with wheel rim,
It is characterized in that, flow spoiler hold-down support identical with well width is set on wheel rim, is distributed on flow spoiler hold-down support
There is not equidistant card slot, flow spoiler blade is fixed in card slot, there is certain angle in card slot direction with rim width direction.
The present invention can be also achieved by the following measures：Flow spoiler blade is made of petiole and leaf fan, and petiole is used for leaf
Fan couples with the card slot of flow spoiler hold-down support, and leaf fans width and is no more than deflected width of tyre, and leaf fan height is disconnected no more than tire
Face height.
The number of flow spoiler blade should be the odd number not less than 3.
Flow spoiler hold-down support is cassette structure, and the both ends of cassette tape are machined with claw and buckle respectively, and claw is inserted into
Cassette tape is set to form circular ring structure in buckle.
Card slot direction and the angle in rim width direction are less than 30 degree.
The invention has the advantages that it is simple in structure, under the premise of not changing tire construction, by tire and wheel rim
The mode for increasing turbulence blades in total member changes tire cavity mode of oscillation, what reduction was resonated with vehicle suspension system
Possibility increases driver comfort and quietness.Meanwhile the present invention be completely it is detachable, can after re-type and wheel rim
Repeated removal uses.

Specific implementation mode
The present invention is equipped with wheel rim 3 in the figure, and flow spoiler identical with well width is set on wheel rim 3 and fixes branch
Seat 2 is distributed with not equidistant card slot 2-3 on flow spoiler hold-down support 2, flow spoiler blade 1 is fixed in card slot 2-3, in order to
Increase the seating surface of turbulence blades 1, there is certain angle in the directions card slot 2-3 with 3 width direction of wheel rim.Flow spoiler blade 1 is by leaf
Handle and leaf fan composition, petiole is used to fan on leaf to be coupled with the card slot 2-3 of flow spoiler hold-down support 2, and leaf fans width and is no more than tire
Section width, leaf fan height are no more than tire section height.Leaf is fanned gas barrier in tyre cavity body, and discontinuous length is formed
Different gas chambers change cavity mode of oscillation.The number of flow spoiler blade 1 should be the odd number not less than 3, and such as 3,5,7 ..., flow-disturbing
Distribution spacing of the device blade 1 on 3 circumferencial direction of wheel rim should be not equidistantly, is conducive to disperse resonance spectrum, avoids single frequency
The resonance mode of rate.Flow spoiler hold-down support 2 is cassette structure, and the both ends of cassette tape are machined with claw 2-2 and buckle 2- respectively
1, claw 2-2, which are inserted into buckle 2-1, makes cassette tape form circular ring structure.
As shown in Figure 1, Figure 2, Figure 3 shows, flow spoiler blade 1 of the present invention is fixed on flow spoiler hold-down support 2 by snap
Card slot 2-3 in, the similar waistband after being unfolded of flow spoiler hold-down support 2, after flow spoiler hold-down support 2 is wound on rim gutter bottom, by card
Pawl 2-2 passes through buckle 2-1, the artificial flow spoiler hold-down support 2 that tenses to be fixed in rim gutter bottom.
Flow spoiler blade 1 is fanned by leaf and petiole forms, and leaf fan height H is for 1 peak of flow spoiler blade to wheel rim 3 and directly
The distance of diameter.Meet H=0.5Hs~0.7Hs, the 4 design section height of Hs finger wheels tire.It is the most wide position of blade that leaf, which fans width W,
Set the distance at place.Meet W=0.7Ws~0.8Ws, Ws finger wheel tire design section width.
Flow spoiler hold-down support 2 is the cassette tape for being distributed several not equidistant card slot 2-3, and claw 2-2 passes through buckle 2-1, shape
At circular ring structure.Cassette tape width Wb meets Wb=Wg, the width of Wg finger wheel rim slot bottoms.Cassette tape length Lb meets Lb=1.01*PI*
Dg, PI are pi, and Dg is the diameter at rim gutter bottom.The directions card slot 2-3 should have certain angle A b with 3 width direction of wheel rim,
Meet Ab≤30 °.
After flow spoiler is packed into tire 4, the air column for being divided into length different tire cavity gas, tire 4 is in rolling process
In, irregular movement is presented due to the blocking of flow spoiler blade 1 in empty intracavity gas, avoids the formation of the vibration mould of fixed frequency
State reduces the possibility to resonate with vehicle suspension.
Flow spoiler material should be selected with some strength and flexible high molecular material, because breaking the barriers in tire
Or when complex road surface, tyre deflection can have a greater change, and tire inner surface has the possibility hit with flow spoiler blade
Property.Flexible material fractures when can be to avoid they strike, scratches tire inner surface, destroys tyre air tightness.
