Description

[Detailed description of the invention] The present invention relates to the invention of a wheel for a vehicle, which ensures both sufficient lightness and aesthetics than when the wheel is made of aluminum alloy material, and also provides appropriate strength at the rim part. It was designed to tighten it.

Ensuring lightweightness for vehicle wheels is essential in order to achieve energy-saving effects, and for this reason, aluminum alloys have traditionally been used to form wheels. Wheels made of such aluminum alloys have an oxide film formed on their surfaces, and are inferior in brightness, and even if an alumite film or the like is formed, it is not possible to obtain a sufficient aesthetic appearance. In other words, it is important for such vehicles to have a sense of speed, and this is especially strongly required for wheels, which are the means of driving.However, oxide films such as aluminum oxide or alumite exhibit a dull feeling, and do not have a sense of speed or strength. I can't help but feel that it lacks sex. Although the use of step-alloyed material may be superior to pure aluminum in terms of strength, it is not sufficient.
In particular, since it is a soft metal, it is susceptible to friction scratches and other damage, and from this point of view it cannot be used as a desirable wheel.

The present invention was devised through research to eliminate the disadvantages of the conventional ones as described above.
The specific embodiment shown in the attached drawings will be explained. This embodiment shows a case where it is formed by three members: a disk part 1, an inner rim part 2, and an outer rim part 3, In such a case, in the present invention, a stainless steel material layer 3a is polymerized and bonded to at least the inner circumferential surface (outer surface) side of the outer rim portion 3, and the specific manufacturing method thereof is to bond an aluminum alloy plate and It goes without saying that the clad material may be formed from a stainless steel plate, but in some cases, a stainless steel plate and an aluminum alloy plate may be bonded together by polymerization. In any case, the rim base layer made of an aluminum alloy plate is approximately 3 to 4 mm thick, whereas the stainless steel plate layer 3a is less than one tenth of this thickness (0.2 mm).
A thickness of about 0.3 mm is sufficient. Disk part 1
As shown in the figure, a shaft mounting hole 5 and the like are formed in the mounting seat 2b of the inner rim portion 2 and the mounting seat 3b of the outer rim portion 3 as described above.
As shown in the figure, it is fastened to the mounting seat 1b of the disk portion 1 by the screws. Note that the outer rim part 3
Regarding the inner rim portion 2, the stainless steel plate layer 3a may be polymerized and bonded to the outer circumferential surface as well as the inner circumferential surface as shown in the figure, and the stainless steel plate layer 3a may be bonded to either the inner circumferential surface or the outer circumferential surface or both of the inner circumferential surface of the inner rim portion 2. May be formed. In addition, in the illustrated tire, a sealing material 6 made of silicone rubber or other material is filled between the outer rim portion 3 and the inner rim portion 2, so that the tire can be mounted using a tubeless method. .

According to the present invention as described above, the outer rim portion 3 has at least its inner peripheral surface (outer surface) as described above.
Since it is formed by polymerizing and adhering a stainless steel plate layer on the side, sufficient shine is obtained from stainless steel, and the sense of shine is similar to that of the wheels of vehicles, which are the actual means of driving. This stainless steel plate layer naturally has excellent hardness and strength, sufficiently preventing damage from friction scratches, etc., and the aluminum alloy base. The strength of layer 3 is improved at the rim portion, and even if a stainless steel plate is used, the thickness relationship is less than 1/10 as described above, and thereby the strength is improved as described above. This makes it possible to reduce the thickness of the rim portion, sufficiently maintain the lightweight characteristics of the rim portion, and provide a high-quality vehicle wheel with excellent aesthetics. This is a great idea.
