Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tire wheel ring, and more particularly to a tire wheel ring for correcting unbalance of a wheel with a tire in a rotating state.
[0002]
[Prior art]
Conventionally, in order to correct the unbalance of a wheel with a tire in a rotating state, the balance is mainly made of lead and using a metal fitting for attachment to the rim end surface of the wheel or a weight having an adhesive layer adhered to the rim surface. It is attached at a position that balances the unbalanced amount of the tire measured with the measuring device.
[0003]
[Problems to be solved by the invention]
However, in such a conventional technique, in order to reuse the weight at the time of balance correction, it is necessary to remove and replace the mounting bracket or the fixing adhesive layer, which is difficult to reuse as it is. As a result, it is necessary to discard the used weight, but there is a problem in disposal because the material of the weight is lead.
[0004]
Further, the balance correction accuracy is required more than ever due to the demand for higher speed of the vehicle and the comfort of the user, and it is not possible to cope with the increment of 5 g which is a general weight supply unit. For this reason, the weight is cut and adjusted, but in this case, the fraction of the weight that has become a fraction is almost always a small piece that cannot be diverted and must be discarded. In some cases, the material is lead, which causes disposal problems.
[0005]
In addition, since the weight is fixed at an appropriate mounting location for correcting the unbalance of each wheel with tire, it is difficult to specify the mounting location, and it is both expensive and labor intensive to remove the wheel when it is discarded.
[0006]
In addition, it is known that when there is an imbalance in the rotating body, if an object that flows into the rotating body is put inside, it will gather at the place where the imbalance is corrected and has the effect of reducing vibrations. It is conceivable to place a diffuser made of powder or granules that can move freely inside the tire in the air chamber, but this is mixed with the diffuser in the air that mainly supports the tire load Means that. However, tire air pressure varies depending on the season and a minute leak from the air seal layer or valve of the tire necessitates replenishment of compressed air. Under general conditions, compressed air contains moisture. In many cases, the moisture impedes the fluidity of the diffuser inside the tire, or solidifies to reduce the effect of correcting the imbalance or to become a new cause of imbalance.
[0007]
The present invention has been made in view of the above problems, and the amount of unbalance correction of a wheel with a tire can be reduced to reduce the amount of balance weight necessary for correction, and balance weight waste generated at the time of rim assembly and rim assembly can be reduced. It is an object to provide a ring for a tire wheel that can be reduced.
[0008]
[Means for Solving the Problems]
The ring for a tire wheel of the present invention according to claim 1 is disposed on the inner side of the rim of the wheel, and a ring-shaped ring body extending in the tire circumferential direction;
A ring-shaped filler formed in the ring body and extending in the tire circumferential direction;
A balance fluid filled in the filling portion;
A diffuser mixed in a predetermined amount in the balance fluid and having a greater specific gravity than the balance fluid;
Stirring means provided on the inner peripheral surface of the filling portion for stirring the balance fluid;
It is characterized by having.
[0009]
Therefore, when the tire is rotated, the balance fluid flows in the ring-shaped filling portion formed in the ring body of the tire wheel ring disposed on the inner side of the rim of the wheel, and in the balance fluid. A diffuser, for example, granules, powder, and liquid, mixed in a predetermined amount and having a higher specific gravity than the balance fluid, diffuses uniformly into the balance fluid due to the flow of the balance fluid, and then the tire assembled on the wheel is unbalanced. In this case, the diffuser gathers at a place where the imbalance in the filling portion is corrected, thereby reducing the vibration of the tire. As a result, the unbalance correction amount of the tire assembled on the wheel is reduced, the amount of balance weight required for the correction can be reduced, and the balance weight waste generated at the time of rim assembly and rim assembly can be reduced. In addition, since this tire wheel ring is filled with a balance fluid in the filling portion, the diffuser is solidified compared to the prior art in which the diffuser is mixed in the air mainly supporting the tire load. No problems occur. In addition, the tire wheel ring can be attached to a conventional wheel and can be removed from the wheel and reused. Further, when the balance fluid flows in the ring-shaped filling portion, the balance fluid is effectively stirred by the stirring means formed on the inner peripheral surface of the filling portion. As a result, the diffuser in the balance fluid that has settled on the tire contact surface side in the filling portion before the tire-equipped wheel rotates is quickly squeezed into the balance fluid by the agitation of the balance fluid performed simultaneously with the rotation of the tire-equipped wheel. To spread. Therefore, after that, since the diffuser gathers at a place where the unbalance in the filling portion is corrected, the unbalance correction during the rotation of the wheel with the tire is completed in a short time.
[0010]
As the balance fluid, a gas such as air, a liquid such as water or oil, and preferably a gel-like liquid with low flow resistance can be used.
[0013]
The stirring means may be provided on one, a plurality, or all of the outer inner peripheral surface, inner inner peripheral surface, and inner peripheral side surface of the filling portion, but the diffuser moves outside the filling portion by centrifugal force. Therefore, in order to effectively diffuse the diffuser, it is preferable to provide it on the outer peripheral surface of the filling portion.
[0014]
According to a second aspect of the present invention, in the ring for a tire wheel according to the first aspect , the ring body and the filling portion extend in the rim width direction, and both end portions reach the vicinity of both end portions in the rim width direction. It is characterized by.
[0015]
Therefore, in addition to the contents of claim 1 , the dimension of the filling portion in the rim width direction can be increased, and the dimension of the rim radial direction can be decreased. That is, since the balance fluid and the diffuser can be disposed as far as possible in the rim radial direction, the balance correction effect is improved.
[0016]
According to a third aspect of the present invention, in the tire wheel ring according to any one of the first and second aspects, the filling portion is divided into a plurality along the rim width direction.
[0017]
Therefore, in addition to the contents of any one of claims 1 and 2 , by dividing the filling portion into a plurality along the rim width direction, the amount and material of the balance fluid and the diffuser in each filling portion can be changed. This improves the balance correction accuracy.
[0018]
According to a fourth aspect of the present invention, in the ring for a tire wheel according to any one of the first to third aspects, the ring main body is filled to fill the filling portion with the balance fluid and the diffuser. It has a mouth and an air vent.
[0019]
Therefore, in addition to the content described in any one of claims 1 to 3 , the balance fluid and the filling portion can be supplied to the filling portion through the filling port while air is extracted from the filling portion through the air removal port at the time of manufacture. Since the diffuser can be filled, the filling operation can be performed smoothly.
[0020]
According to a fifth aspect of the present invention, in the ring for a tire wheel according to any one of the first to fourth aspects, the ring body is a filling for filling the filling portion with the balance fluid and a diffuser. It has a mouth and an air vent.
[0021]
Therefore, in addition to the content described in any one of claims 1 to 4 , when the diffuser gathers in a place where the imbalance in the filling portion is corrected, the diffuser is disposed on the rim outer peripheral side of the filling portion. It is possible to prevent biasing to one side in the rim width direction.
[0022]
The ring for a tire wheel of the present invention according to claim 7 is disposed on the inner side of the rim of the wheel and has a ring-shaped ring body extending in the tire circumferential direction,
A ring-shaped filler formed in the ring body and extending in the tire circumferential direction;
Stirring means provided on the inner peripheral surface of the filling portion for stirring the balance fluid;
A filling port and an air vent port formed in the ring body and for filling the filling portion with a balance fluid and a diffuser having a larger specific gravity than the balance fluid;
It is characterized by having.
[0023]
Therefore, in this ring for a tire wheel, it is possible to fill the filling portion of the ring body with the balance fluid and the diffuser through the filling port, and at this time, the air in the filling portion can be extracted through the air vent port. . Therefore, when the tire wheel ring is attached to the wheel, and the tire-equipped wheel with the tire attached to the wheel is rotated, the balance is formed in the ring-shaped filling portion formed in the ring body and extending in the tire circumferential direction. As the fluid flows, a predetermined amount of diffuser mixed in the balance fluid and having a specific gravity greater than that of the balance fluid is uniformly diffused in the balance fluid by the flow of the balance fluid, and then the tire wheel is unbalanced. In some cases, the diffuser collects at a location that corrects the imbalance in the filling, reducing the vibration of the tired wheel. As a result, the unbalance correction amount of the wheel with tire is reduced, the amount of balance weight required for the correction can be reduced, and the balance weight waste generated at the time of rim assembly and rim assembly can be reduced. In addition, problems such as solidification of the diffuser do not occur as compared with the conventional technique in which the diffuser is mixed in the air mainly supporting the load of the tire. In addition, the tire wheel ring can be attached to a conventional wheel and can be removed from the wheel and reused. Further, when the balance fluid flows in the ring-shaped filling portion, the balance fluid is effectively stirred by the stirring means formed on the inner peripheral surface of the filling portion. As a result, the diffuser in the balance fluid that has settled on the tire contact surface side in the filling portion before the tire-equipped wheel rotates is quickly squeezed into the balance fluid by the agitation of the balance fluid performed simultaneously with the rotation of the tire-equipped wheel. To spread. Therefore, after that, since the diffuser gathers at a place where the unbalance in the filling portion is corrected, the unbalance correction during the rotation of the wheel with the tire is completed in a short time.
