に関する。This invention relates to a resin wheel that has excellent mechanical properties such as bending strength, rigidity, heat resistance, fatigue resistance, and creep resistance, and is lightweight and easy to mass produce.
[従来の技術]
従来、ホイールのうち、例えば自動車用ホイールは、一
般にスチール又は軽合金(アルミ合金。[Prior Art] Conventionally, among wheels, for example, automobile wheels are generally made of steel or light alloy (aluminum alloy).

のビードシート部の真円度に狂いが生じ易いという欠点
があり、また、重量が重いため重量の点でも自動車部品
の軽量化の面で好ましいものではない。Steel wheels are manufactured by press or roll forming, but there are many variations in forming dimensions, and the disadvantage is that the roundness of the bead seat part of the rim tends to be easily distorted. This is also not preferable in terms of weight reduction of automobile parts.
これに対し、軽合金製ホイールは成形寸法が安定してお

軽量化がなされているものの、スチール製ホイールに比
し材料コストが3〜5倍と非常に高価なものであるとい
う欠点がある。On the other hand, light alloy wheels have stable molded dimensions and are significantly lighter than steel wheels at 173 mm, but the material cost is 3 to 5 times that of steel wheels. The disadvantage is that it is very expensive.
ところで、近年重視されている省エネルギーの観点から
、自動車部品の軽量化は極めて重要な要件となるが、と
りわけ、ホイールのようなバネ下部材は、燃費の改善1
機動性の向上の点から、より一層の軽量化が望まれてい
る。Incidentally, from the perspective of energy saving, which has been emphasized in recent years, reducing the weight of automobile parts is an extremely important requirement, and unsprung parts such as wheels are especially important for improving fuel efficiency.
In order to improve maneuverability, further weight reduction is desired.
このような背景のもとに、最近になって、軽量性、成形

法の安定性に優れる上に、生産性も良好で製品のコスト
ダウンが図れ、しかも彩色等のデザイン性の面において
も極めて優れるものと期待がよせられる。Against this background, resin wheels have recently been proposed as lightweight, molding stable, and low-cost wheels. Resin wheels are molded mainly from FRP, which is a mixture of resin and reinforcing short fibers or long fibers, and are lighter than metal wheels and have superior stability in molded dimensions, as well as higher productivity. It is expected that the product will be of good quality, reduce the cost of the product, and be extremely superior in terms of design such as coloring.
このような樹脂製ホイールに要求される特性としては、 ■ 破壊防止の面から、衝撃強度が高いこと。The characteristics required for such resin wheels are as follows: ■ High impact strength to prevent destruction.
■ ホイールからのタイヤの脱離防止の面から、クリー
プが小さいこと。■ Creep must be small to prevent the tire from coming off the wheel.
■ ブレーキドラムの熱に対して耐熱性に優れること。■ Excellent heat resistance against the heat of the brake drum.
■ ユニフォーミティに優れること。即ち、ホイールは
自動車にとって重要な部品の一つであるため、成形品に
不均一部や欠陥部があるものは、ホイールとして使用す
ることはできない。■ Excellent uniformity. That is, since wheels are one of the important parts for automobiles, molded products with uneven or defective parts cannot be used as wheels.
■ 量産化が可能であること。■ Mass production is possible.
ところで、一般にホイールは、第4図(上半分の断面図

体に成形される1ピースホイールと、リム部1とディス
ク部2が各々独立に成形された後両者を金属ボルトで接
合して一体化された2ピースホイールとに大別される。By the way, a wheel generally consists of a rim part 1, a disc part 2 in which a hub bolt hole 3 is formed, etc., as shown in Fig. 4 (cross-sectional view of the upper half), but commercially available aluminum wheels are classified from the structural point of view. Then, a one-piece wheel in which the rim part 1 and the disc part 2 are integrally molded, and a two-piece wheel in which the rim part 1 and the disc part 2 are molded independently and then joined together with metal bolts to be integrated. It is broadly divided into.

その部分を金属ボルトで接合するため、1ピースホイー
ルよりも重量が増加するという短所を有する。A two-piece wheel has a great advantage over a one-piece wheel in that by changing the design of the disc part 2 while keeping the rim part 1 the same, it is possible to provide wheels with a variety of combinations. has. On the other hand, in order to join the rim part 1 and the disc part 2, it is necessary to provide an overlapping part between them, and furthermore, this part is joined with metal bolts, so it has the disadvantage that it is heavier than a one-piece wheel.
これに対して、樹脂製ホイールは当然その軽量性を大き
なセールスポイントとするため、できるだけ重量増加に
つながる構成が避けられる。このため、従来の樹脂製ホ
イールは射出成形によるものでも圧縮成形によるもので
も、1ピースホイールとすることを前提として開発され
ているのが現状である。On the other hand, a plastic wheel naturally has its light weight as a major selling point, so structures that increase weight can be avoided as much as possible. For this reason, the current situation is that conventional resin wheels, whether made by injection molding or compression molding, are developed on the assumption that they will be one-piece wheels.
【発明が解決しようとするaIMコ

点がある。[aIM to be solved by the invention] Of the conventional molding methods for resin wheels, wheels manufactured by compression molding have relatively minor fiber damage during molding, so they are superior in terms of rigidity, strength, etc. . Furthermore, since the resin used is mainly a thermosetting resin, the heat resistance and creep resistance are also good. However, it is not suitable for molding complex-shaped objects (for example, objects with significant changes in wall thickness).
Furthermore, the molding cycle is long, resulting in poor productivity.

のところ、射出成形による樹脂製ホイールが完成され、
市販された事実はない。On the other hand, injection molding has extremely high productivity and is superior in terms of production cost, but injection molded products generally have the disadvantage that the strength is 1/3 to 115 lower than that of compression molded products. This is due to fiber breakage during resin kneading and flow.
This is due to the orientation of fibers and molecules caused by flow, the occurrence of felt lines at resin confluence points, etc., which cause the physical properties of the material constituting the molded product to become uneven or deteriorate, resulting in a decrease in strength. Particularly in the case of wheels, there are many knot holes in the disc part for design purposes and to increase the air cooling effect during rotation, and there are also bolt holes for joining the drum of the car body. Therefore, the shape is such that weld lines occur frequently. For this reason, to date, resin wheels made by injection molding have been completed.
There is no evidence that it has been commercially available.

The objective is to provide a resin wheel that has excellent mechanical properties such as fatigue resistance and creep resistance, and can be mass-produced at low cost.

め、補強繊維の直径は0.1〜100μm、特に0.5
〜50μmの範囲とするのが好ましい。In the present invention, examples of the reinforcing fibers to be added to the synthetic resin include fibers of glass, carbon, graphite, aramid, polyethylene, ceramics (S i C, AJ2203, etc.), metals (boron, stainless steel, etc.), and the like. Such reinforcement! If the diameter of the a-fibers is too small, a sufficient reinforcing effect cannot be obtained; on the other hand, if the diameter is too large, injection compression molding becomes difficult and moldability deteriorates. For this reason, the diameter of the reinforcing fibers is 0.1 to 100 μm, especially 0.5 μm.
It is preferable to set it as the range of 50 micrometers.
このような補強繊維の配合量が少な過ぎると十分な補強

。If the amount of such reinforcing fibers is too small, a sufficient reinforcing effect will not be obtained, and if it is too large, the matrix resin will be insufficient, resulting in poor moldability. For this reason, the blending amount of reinforcing fibers is preferably 5 to 70% by volume, particularly preferably 10 to 60% by volume, relative to the molding material.

補強樹脂を混合して使用することは極めて有効である。In the present invention, particularly preferred molding materials include granules obtained by cutting rod-shaped bodies with a diameter of 2.5 to 3 mm into lengths of, for example, 10 mm, which are formed by pultrusion molding using continuous fibers and thermoplastic resin. In this case, as mentioned above,
The length of the reinforcing fibers contained can be arbitrarily adjusted by changing the cutting length. Furthermore, since it is formed by pultrusion molding, resin impregnation between the fibers is sufficient despite the long fibers. In addition, as mentioned above, although the mechanical properties of this type of long fiber reinforced resin are significantly improved compared to ordinary short fiber reinforced resin, there is almost no loss in moldability or processability, and the same level of Good moldability and workability can be obtained. In addition, in order to improve the processability of these long fiber reinforced materials, it is extremely effective to mix and use ordinary short fiber reinforced resins.

法を組合せて成形されてもよい。In the present invention, any of the compression molding method, injection molding method, or injection compression molding method may be used as a method for molding each segmented molded body using such a molding material. The weld line is made into two pieces (
In view of the fact that this can be avoided by dividing the mold into two or more parts, it can be said that the present invention is particularly effective when molding is performed by injection molding or injection compression molding. Of course, each divided molded body of the resin wheel that is molded separately may be molded by any one of the three molding methods described above, or may be molded by a combination of a plurality of different molding methods.

される成形方法が好適である。The injection compression molding method described in the present invention is a method in which the mold is opened slightly in advance or the mold is closed with a weak mold clamping force, and after the material is injected into the mold, the mold clamping force is increased. This method involves compression molding. In particular, the injection compression molding method described in the present invention involves injecting molten resin into upper and lower molds installed between presses using an injection cylinder or an extruder. A molding method in which the mold is closed is preferred.
ところで、近年、社会環境的な要請から省エネルギーが
さけばれ、前述の如く、自動車部材にも軽量化が望まれ
ている。特に、バネ下部材はその効果が大きく、また機
動性の点からも軽量化が要求されている。Incidentally, in recent years, energy conservation has been avoided due to social and environmental demands, and as mentioned above, weight reduction in automobile parts is also desired. In particular, unsprung members are highly effective and are required to be lightweight from the viewpoint of maneuverability.

The parts to which these structures are introduced may be the entire wheel, only the rim part, only the disc part, or can be used in other necessary parts as appropriate.
補強構造としては、例えば第12図に示す如く、ある種

適である。By the way, a wheel is usually attached to a disc adjacent to a brake drum or a brake disc via hub bolts. Therefore, the area around the hub bolt hole is directly affected by brake heat generation, and during long-term use, stress relaxation occurs as the resin softens and creeps, causing the hub nut to loosen. In order to solve this problem, for example, Fig. 13(a) (cross-sectional view near the hub part), (b) (enlarged view of section B in Fig. 13(a)), and (C) (Fig. 13(
As shown in the cross-sectional view taken along line C-C in b), the hole 22 of the hub bolt 21 of the resin wheel 10 has high rigidity, high strength,
It is preferable to use a structure in which a heat-resistant member 20 is fitted and the force for tightening the hub nut 22 is transmitted to the brake drum 24 through this fitted member. (In the figure, 25 is a tire.) In this case, the material of the member 20 to be fitted is metal, heat-resistant plastic, and FRP thereof.

In this case, the locations where such improvements are made are, for example, as shown in Figure 14.
Partial surface 31 of the disk portion 2 or the entire surface 3 of the disk portion 2

For example, by embedding and integrally molding an abnormality warning device such as a tire bank warning device into a wheel, a safe automobile suspension component can be provided in which the wheel and tire are integrated. It is also easy to integrally mold a fail-safe mechanism, such as a rib on the rim of the wheel, with the wheel.
