本発明は、自動車等の車両用ホイールに関し特に繊維強
化樹脂製のホイールに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to wheels for vehicles such as automobiles, and particularly to wheels made of fiber reinforced resin.

おいては、ディスク部のナツトによって締付けられる部
分にクリープが生じないように配慮する必要がある。1ffLJ In recent years, in order to reduce the weight of vehicles, it has been proposed that wheels be made of fiber reinforced resin (FRP). Generally, a vehicle's disc wheel is attached to the axle hub by inserting a hub bolt installed on the axle hub into a hub bolt insertion hole provided in the disc part and tightening it with a nut, but resin materials are compared to metal materials. Therefore, in fiber-reinforced resin wheels, care must be taken to prevent creep from occurring in the portion of the disk portion that is tightened by the nut.

The metal sleeve is insert-molded concentrically into the disc wheel body, and the tightening force from the nut is received by the metal sleeve.

It has been shown to strengthen the

製作も面倒になる。However, if an elastic washer is inserted between the nut mounting surface and the nut as in the above-mentioned Utility Model Application No. 60-182202, it is necessary to attach a washer to each nut, so the installation is difficult. The work is troublesome, the wheel becomes heavier by the weight of the washer, and the shape of the seat surface and the shape of the washer must match, making the manufacture of the wheel and the washer complicated.

の界面において剥離を生じ易い。In Japanese Utility Model Application Publication No. 63-51801, a large diameter metal insert member is insert-molded into the disc wheel body, so the weight of the wheel becomes considerably heavy. Further, since the elastic modulus of the resin and metal is significantly different, the mutual followability between the resin part and the metal part is poor during deformation, and peeling is likely to occur at the interface between the two.

コストの上昇を招く。Furthermore, according to the above-mentioned Japanese Utility Model Application No. 62-121921, a large number of long fibers must be oriented around the bolt through hole in the axial direction of the through hole, which increases the manufacturing process and increases the manufacturing cost. .

In the present invention, in an m#I71 reinforced resin wheel having a hub bolt insertion hole in the disk portion, fibers having higher creep resistance than the fiber reinforced resin constituting the disk portion are provided in the hub bolt insertion hole portion of the disk portion. An insertion piece made of reinforced resin is inserted and fitted over the entire thickness of the disk portion, and the hub bolt insertion hole is formed in the insertion piece.

Next, this molded material is pressed against the lower mold by an upper mold and heated to be fluidized, and the insert piece is inserted and fixed into the molded material, thereby producing the molded material.

ので、両省の連結を極めて強固にすることができる。According to the present invention, since the portion of the disk portion that is tightened by the nut is formed by an inserted piece of fiber-reinforced resin having particularly high creep resistance, the occurrence of creep can be effectively prevented. Therefore, there is no need to use a large washer plate to reduce the surface pressure caused by the nut tightening force, and the insertion piece itself is made of fiber-reinforced resin, which is lighter than metal. , the wheel fuffi becomes lighter. Further, since both the disk portion and the insertion piece are made of raN reinforced resin and there is no significant difference in their elastic modulus, the followability between the two is good during deformation, and no peeling occurs at the interface between the two. Since the rough disk portion and the insertion piece can be integrally molded by heat and pressure molding, the connection between the two parts can be made extremely strong.

強化ＰＥＳ樹脂で作られている。The wheel 1 is fixed to the axle hub 2 by passing the hub bolt 3 through the hub bolt insertion hole 6 and tightening the nut 7 screwed onto the hub bolt 3 via the washer 8. It is not provided directly in the carbon fiber reinforced nylon 6 to be formed, but is provided in the insertion piece 9 fitted into the wheel body at the attachment portion. The insert piece 9 is made of a fiber-reinforced resin that forms the wheel body, that is, in this embodiment, a fiber-reinforced resin that has significantly higher creep resistance than the carbon fiber-reinforced nylon 6, such as PES (polyethersulfon) resin, reinforced with carbon fibers. Made of carbon reinforced PES resin.

樹脂でできているのでクリープを生ずることはない。The insertion piece 9 passes through the wheel body in the thickness direction, and both side surfaces thereof are flush with both side surfaces of the wheel body. One side surface contacts the surface of the axle hub 2, and a pressing force is applied to the other side surface by tightening the nut 7 via the washer 8. In this way Natsuto 7
The tightening force is applied only to the insertion piece 9, and this insertion piece 9
As mentioned above, carbon fiber reinforced PES with high creep resistance
Since it is made of resin, it does not cause creep.

能である。In addition, since the insert piece 9 can withstand high surface pressure, the washer 8 can be made relatively small in diameter, and together with the fact that the insert piece 91 is made of lightweight fiber-reinforced resin material, it is possible to prevent the wheel from turning into pumice. Contribute. The washer 8 is formed with a spherical tightening seat surface 8a, and the spherical tightening portion 1 of the nut 7 is attached to the seat surface 8a.
a is in pressure contact. It is of course possible to use a normal tightening nut in place of such a nut 7.

It is manufactured by heating and pressure molding using a mold consisting of. Pins 14 having substantially the same diameter as the hub bolts 3 are provided in the lower die 11 at positions corresponding to the hub bolt insertion holes 6, respectively. First, as shown in FIG. 2, a preformed insert piece 9 is positioned on the lower mold 11 by passing its hub bolt insertion hole through the pin 14, and a carbon fiber-nylon 6 composition is placed on the upper part of the insert piece 9. A wheel body molding material 15 consisting of the following is placed. Next, the molds 11, 12, and 13 are closed as shown in FIG. 3 after they are sufficiently heated, and when the molding material 15 is heated and pressurized, the thermoplastic nylon 6 becomes fluid, and the carbon fiber- The nylon 6 composition spreads throughout the mold cavity and wraps around the insert 9 along its outer circumferential surface. When this is taken out from the mold after being cooled and solidified, an inserting piece 9 is inserted into a predetermined position of the disk portion 5 to obtain a wheel 1 integrally molded, as shown in FIG.
