ヤのリム組み工程を省略できる。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of integrally forming a tire and a wheel at the time of molding a wheel to form a tire wheel. More specifically, a rubber tire is used as a resin wheel molding die. After setting in a part of the cavity, by filling the remaining part of the cavity of the mold with a molten resin containing glass, fibers such as carbon, etc., the tire and wheel are integrated, lightweight and uniform. The present invention relates to a method for forming an excellent tire wheel. In particular, in the present invention, in the tire wheel, the tire rim assembling step, which was conventionally disadvantageous for obtaining good uniformity, can be omitted.

まりつつある。2. Description of the Related Art From the viewpoint of energy saving, which has been emphasized in recent years, it has been strongly desired for automobiles to be lightweight, and unsprung members such as wheels are also required to improve fuel efficiency and mobility. Therefore, the demand for weight reduction is increasing year by year.

有し、また、軽合金製ホイールは、スチール製ホイール
に比べて、１／３程度の重量である反面、材料コストが
３〜５倍と非常に高価であるという欠点を有する。Wheels are generally made of steel or light alloys (eg, aluminum alloys, magnesium alloys), but steel wheels have the disadvantage of being heavy, and light alloy wheels are made of steel. Although the weight is about 1/3 of that of the wheel made, it has a drawback that the material cost is 3 to 5 times, which is very expensive.

という利点がある。Therefore, it is necessary to develop a lightweight wheel without increasing the material cost. Against this background, FRP (fiber reinforced plastic) resin wheels, in which short fibers or long fibers are mixed with resin, have recently attracted attention. Compared with metal wheels, this resin wheel is lighter in weight and excellent in moldability, and has the advantages of good productivity and cost reduction of the product, and also extremely excellent in designability such as coloring. is there.

動させてタイヤをリム組みする。[0006] A tire wheel is usually formed by a method in which the tire and the wheel are manufactured separately, and then the tire is assembled to the rim of the wheel. Explaining the rim assembly procedure of the tire by this method, first, a lubricant, for example, soap water or oil, etc., is applied to the rim flange portion and the bead seat portion, and the bead portion surface of the tire corresponding thereto, Next, while rotating the tire and the wheel, one tire bead portion is sequentially dropped into the center drop portion of the wheel, and then the remaining tire bead portion is similarly dropped into the center drop portion,
Finally, by utilizing the tire internal pressure by filling the inside of the tire, the tire bead part dropped into the center drop part is placed on the bead seat part of the rim in the width direction of the rim until it contacts the flange part. Slide the tire outward to rim the tire.

If the uniformity of tires and wheels is bad, the steering stability, vibration, and riding comfort of the automobile are adversely affected. Therefore, it was necessary to develop means for improving the uniformity of tires and wheels.

Another object of the present invention is to provide a method for forming a tire wheel that is lightweight and excellent in uniformity.

いたリム組み工程を省略できる利点がある。According to the present invention, a toroidal rubber tire in which the left and right bead portions are separated from each other is united with a rim member which is tightly fitted to the inner peripheral surface of the bead portion and the inside of the tire is filled with fluid. In this state, set it in a part of the cavity of the resin wheel mold that matches the outer contour of the rubber tire, and then fill the remaining part of the cavity with molten resin The tire does not deform due to resin pressure that sometimes occurs, and the bead portion of the tire can be evenly arranged on the rim of the wheel while maintaining the original design shape of the tire, and as a result, in the tire wheel, Vibration in the radial direction, the width direction, and the circumferential direction is reduced, good uniformity is obtained, and rolling resistance during load rolling of the tire is also reduced. Moreover,
There is an advantage that the rim assembling process, which has been a cause of deteriorating the uniformity of tire wheels, can be omitted.

によって、より強固に接合し一体化できる。Further, by firmly fixing the bead portion of the tire by surrounding the bead portion, specifically, by sandwiching the bead portion between the inner flange portion and the outer flange portion and firmly fixing the bead portion, Since it is possible to reduce the amount of the bead wire that is a constituent member of the tire and occupies a large proportion of the tire weight, the weight of the tire itself can be reduced, and the weight of the resin wheel can be reduced, and the weight of the tire wheel can be significantly reduced. In addition, by providing the protrusion or the depression on the inner peripheral surface of the rim member, the rim member and the resin can be more firmly joined and integrated by the so-called anchor effect.

(1) Role of rim member The rim member 11 mainly prevents the molten resin 3 from entering the inside 9 of the tire when the remaining portion 4b of the cavity 1 of the mold 2 is filled with the molten resin 3. And plays a role in positioning and supporting the bead portion and preventing the tire from being deformed by the resin pressure. The rim member 11 is
As shown in FIG. 3 (a), a tire 5 has a bead seat portion 12 tightly fitted to the inner peripheral surfaces 10 of both bead portions 7,
The tire bead portion 7 has an inner flange portion 13 that is higher than a normal hump for both positioning and support, and the rim member 11 is attached to the tire 5 (FIG. 3B). This attachment can be performed by a normal rim assembly method, but it may be difficult to attach because the inner flange portion 13 is raised. In this case, it is preferable that the rim member 11 is composed of several members cut in the width direction. As an example, a rim member 11 including four members 33a, 33b, 33c, 33d is shown in FIG. In this case, when these members 33a to 33d are assembled to the rim member 11,
In order to prevent the molten resin and the fusible core from entering and exiting through the abutting portion 34 between these members, the abutting portion 34 of each member is, for example, as shown in FIG.
It is preferable to make the cross-sectional shape as shown in (b). The attachment of the rim member 11 to the tire bead portion 7 has no functional problem even if only the frictional force due to fitting is utilized. However, when it is desired to increase the rigidity and strength of the bead portion 7, the tire 5 and the rim member are attached. It is preferable to apply a primer, an adhesive, or the like to a portion where 11 is in close contact before attachment so that this adhesive force is utilized together with the frictional force due to fitting.

Before being set in the mold 2, the inside of the tire is filled so as to have a sectional shape as shown in FIG. The following two methods are conceivable as the method for forming the fusible core. The first method is that the rim member described above is fitted to the tire bead portion, and the fusible material is injected into the inside of the closed space tire to solidify and then the rim member is removed to melt the fusible material. It is a method of forming a sex core. The second method is that a ring-shaped fusible core having a tire cavity cross-sectional shape is made of a fusible material in advance and divided into several parts like the ring member in FIG. Aside
This is a method in which a fusible core is formed in the tire cavity by sequentially inserting these. Therefore, in these cases, it is not necessary to attach the rim member 11 to the tire when the molten resin 3 is filled, and the tire wheel 8 in which the tire 5 and the wheel 6 are integrated is formed as shown in FIG. 6C. it can. As the material of the fusible core 17, a material that does not melt when the molten resin 3 is filled, for example, a low melting point alloy (tin / bismuth alloy or the like), a low melting point resin, a water-soluble resin, or the like is used.

If the diameter of such a reinforcing fiber is too small, a sufficient reinforcing effect cannot be obtained, and conversely if the diameter is too large, molding becomes difficult and moldability deteriorates. Therefore, the diameter of the reinforcing fiber is preferably in the range of 0.1 to 100 μm, particularly 0.5 to 50 μm. If the amount of such reinforcing fibers is too small, a sufficient reinforcing effect cannot be obtained. On the contrary, if the amount is too large, the matrix resin becomes insufficient and moldability deteriorates. For this reason, the amount of the reinforcing fiber blended is 5 in terms of the blending ratio with respect to the molding material.
It is preferably from 70 to 70% by volume, particularly preferably from 10 to 60% by volume.

In this case, as described above, the length of the reinforcing fiber contained can be arbitrarily adjusted by the cutting length.
In addition, since it is formed by pultrusion, the resin impregnation property between the fibers is sufficient despite the long fibers. In addition, this type of long fiber reinforced resin has substantially the same mechanical properties as the ordinary short fiber reinforced resin as described above, but the moldability and workability are hardly impaired, and the same degree is obtained. Formability and workability can be obtained. In order to improve the workability of these long fiber reinforced products, it is extremely effective to mix and use a normal short fiber reinforced resin. In this case, the mixing ratio of the short fiber reinforced resin is 70% of the total weight.
Hereafter, it is preferably 60% or less.
