Abstract

PROBLEM TO BE SOLVED: To reduce the waste of a balance weight which is produced at the time of assembling and reassembling the rim of a tire by reducing the amount of the balance weight required for correction by reducing the unbalance correcting amount of the tire put on a wheel. SOLUTION: A rubber tube 26 is put on the internal surface 24 of a tire 10 faced oppositely to the central part of the tread 22 of the tire 10 in the width direction. The tube 26 is put on the internal surface 24 in a ring-like state along the peripheral direction of the tire 10 and filled up with water 28. Iron powder 30 having a heavier specific gravity than the water 28 has is scattered in the water 28 and, when the tire 10 is set to a rotating state, the scattered iron powder 30 gathers together at an unbalance correcting location in the tube 26 and works to reduce the vibration of the tire 10.

Field of the Invention The present invention relates to a tire provided with a self-unbalance correcting mechanism, and more particularly to a tire provided with a self-unbalance correcting mechanism for correcting an unbalance of the tire itself in a rotating state.

A metal fitting for attaching to the rim end surface of the wheel or a weight having an adhesive layer adhered to the rim surface is attached at a position where the weight is balanced with the unbalance amount of the tire measured by the balance measuring device.

It is difficult to reuse as it is. As a result, it is necessary to discard the used weight,
Since the weight is made of lead, there is a disposal problem.

It is not possible to deal with ticks. For this reason, weights are cut and adjusted, but in this case, the fractional weight part becomes a small piece in most cases and cannot be diverted and must be discarded. Even in this case, there is a disposal problem because the material is lead.

It is known that when a flowing object is placed inside it, it gathers at the place where the imbalance is corrected and has the effect of reducing vibration, and using this, it is possible to freely move inside the tire inside the air chamber inside the tire It is conceivable to include a diffuser consisting of powder or granules, which means that the diffuser is mixed into the air which mainly supports the load of the tire. However, the air pressure of the tire fluctuates depending on the season and small leaks from the air seal layer and the valve of the tire require replenishment of compressed air, but under general conditions, compressed air contains moisture. Is often contained, and this moisture inhibits the fluidity of the diffuser inside the tire or solidifies to reduce the effect of correcting the imbalance or become a new cause of the imbalance.

も発生しない。Therefore, when the tire is in a rotating state, the balance fluid flows in a ring-shaped filling portion provided inside the tread surface of the tire and extending in the circumferential direction of the tire, and is mixed with the balance fluid by a predetermined amount. A diffuser having a higher specific gravity than the balance fluid, for example, particles, powders, and liquids are uniformly dispersed in the balance fluid by the flow of the balance fluid, and thereafter, when the tire assembled to the wheel is unbalanced. Reduces the vibrations of the tires by gathering where the diffuser corrects the imbalance in the fill. As a result, the amount of unbalance correction of the tire mounted on the wheel is reduced, the amount of balance weight necessary for correction can be reduced, and the balance weight waste generated when assembling the rim and when replacing the rim can be reduced. In addition, since the filling portion is filled with the balance fluid, there is no problem such as solidification of the diffuser as compared with the related art in which the diffuser is mixed in air mainly supporting the load of the tire.

液体を用いるのが好ましい。As the balance fluid, a gas such as air, a liquid such as water or oil, preferably a gel-like liquid having low flow resistance can be used, but the pressure of the air filled in the tire does not affect the balance fluid. In order to achieve this, it is preferable to use a liquid that does not have the possibility that the filling portion is compressed by the pressure of the air filled in the tire.

As a result, the diffuser in the balance fluid that has settled on the ground contact surface side of the tire before the rotation of the tire quickly diffuses into the balance fluid due to the stirring of the balance fluid performed simultaneously with the rotation of the tire. Therefore, after that, since the diffusers gather at the place where the imbalance is corrected in the filling portion, the correction of the imbalance during the rotation of the tire is completed in a short time.
