スクホイールに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc wheel in which at least the disc portion is made of a light alloy material such as a magnesium alloy or an aluminum alloy.

The rim portion 2 into which the rim portion 2 is fitted and the disk portion 4 inside the rim portion 2 are joined by welding or the like, or the two are integrally molded. The disk portion 4 is divided into a hub attachment portion 8 that is attached to a hub 7 of the vehicle body by a plurality of hub bolts 5 and nuts 6, and spoke portions 9 that extend approximately radially outward from the hub attachment portion 8.

問題が生じる。Incidentally, recently, light alloy materials such as magnesium alloys have been increasingly used for disc wheels for the purpose of reducing vehicle weight and the like. On the other hand, iron is usually used for the hub on the vehicle body side, so when using a disc wheel whose disc part is made of a light alloy material such as magnesium alloy, it is necessary to use a light alloy material for the hub mounting part. There will be direct contact between the material and the iron of the hub. However, in the contact area between iron and light alloy materials, especially iron and magnesium alloy, corrosion due to the potential difference between the two metals, that is, so-called electrolytic corrosion due to the local battery formation effect, tends to progress, so in the above configuration, the hub Corrosion of the contact portion between the mounting portion and the hub progresses rapidly, which not only impairs the appearance but also causes problems in terms of strength.

て容易に剥離してしまい、したがって前述のような電食
を有効に防１トすることは困難であった。In order to solve this problem, it is possible to paint or coat the surface of the hub attachment part of the disc wheel with an insulating material, but the hub and the hub attachment part come into contact with a strong pressure contact, and moreover, when driving, Because large stresses are applied, and insulation materials and light alloy materials usually have extremely different coefficients of thermal expansion, in reality, simply painting or coating insulation materials will peel off extremely easily due to repeated stress and thermal cycling. Therefore, it has been difficult to effectively prevent electrolytic corrosion as described above.

The part is made of a light alloy or a composite material, and a ceramic sprayed layer is formed on the surface of the hub contacting side of the hub attachment part. The sprayed layer electrically insulates between the hub attachment part and the hub, and the base of the ceramic sprayed layer is a light alloy/fiber composite material, which effectively prevents the ceramic sprayed layer from peeling off. .

It is desirable to use a material with a small coefficient of expansion, but the coefficient of thermal expansion of ceramic I fibers is usually smaller than that of light alloy materials, so from the perspective of the coefficient of thermal expansion, it is better to use either ceramic type 111t. You may do so. In addition, when selecting fibers, please be sure to

ない。When a disc wheel like the one described above is installed on a vehicle body, the ceramic sprayed layer comes into contact with the hub. Because of this ceramic sprayed layer (or insulator C), even if magnesium alloy is used as the base material of the disc wheel,
There is complete insulation between the magnesium base and the W4 hub, thus preventing corrosion. In addition, the thermal sprayed layer has a high bonding strength with the base, and the base is a light alloy/fiber composite layer, so the coefficient of thermal expansion of the base layer is smaller than that of the light alloy alone, in other words. Since the coefficient of thermal expansion is close to that of the ceramic sprayed layer, the ceramic sprayed layer will deteriorate due to repeated stress and thermal cycles during use. There is little risk of peeling off from IW4.

Then, as shown in FIG. 4, the fiber molded body 15 is placed in a predetermined position in the high-pressure casting mold 16, that is, in a position corresponding to the hub attachment part, and a molten magnesium alloy, etc. is placed in the mold. A molten light alloy of 500 to 1500 k (1/c
So-called high-pressure casting is performed by applying a high pressure of approximately ♂, thereby densely filling the molten light alloy into the voids between the fibers of the fiber compact, and after maintaining the pressure of the molten metal until the end of solidification, it is cast from the mold. Remove and heat treat as appropriate. Next, a ceramic material is thermally sprayed onto the hub contact side surface of the hub attachment portion, in which the fibers and the light alloy are compositely integrated, to form a ceramic thermally sprayed layer.

It is also possible to fill the voids between the fibers with a molten light alloy, or it is also possible to use the other oxidizing method described in A above.

It is also possible to apply the high-pressure VJ manufacturing method, centrifugal casting method, or other pressure casting method after coating, blowing, or J-casting.

Set it in the position corresponding to the hub mounting part in the high-pressure casting mold 16, and place it in the 690°C magnesium alloy
MC7) The molten metal was poured into the mold, and then pressurized with a pressure plunger 17 at a pressure of 1800 kg/cIIr and held until solidification. After T6 heat treatment, the rolled disc wheel material was heated to 5.5 J It was processed into a 14-inch shape, and then SiC was thermally sprayed to a thickness of 100 mm on the hub contact side surface of the hub mounting portion by plasma spraying.

It has been recognized that this can be done.

。As is clear from the above explanation, since the disc wheel of the present invention is insulated from the hub by the ceramic molten fJJ layer, the disc wheel is made of a light alloy such as magnesium alloy, which is prone to electrolytic corrosion at the contact surface with the steel hub. Despite using IF, it is possible to effectively prevent corrosion on the hub contact surface, and the bonding strength between the ceramic sprayed layer, which is the main insulating layer, and the underlying light alloy and fiber composite layer. Since the difference in coefficient of thermal expansion between the two layers is high and the difference in coefficient of thermal expansion between the two layers is relatively small, there is little risk that the ceramic sprayed layer will separate due to N return stress or thermal cycles, thus maintaining the electrolytic corrosion prevention function for a long period of time. ′jfJ results such as can be obtained.
