Description

The present invention relates to a wheel for holding a tire of a motorcycle or an automobile (hereinafter referred to as a vehicle).

As a vehicle wheel, there are a spoke wheel in which a rim is supported by a large number of spokes, and a wheel in which a spoke portion and a rim portion are made of steel or aluminum alloy.
Further, since the wheel is very conspicuous as an exterior part of the vehicle, each wheel has a design property in addition to a function for traveling.

However, if the owner of the vehicle wants to change the design of the wheel and claim personality, the wheel itself has to be replaced, resulting in a high cost burden.
Furthermore, exchanging wheels requires a dedicated device such as a tire changer, and it is also necessary to adjust the rotational balance, which is not an easy task for the individual vehicle owner.

Low-priced commercially available wheels include a wheel cap and a resin or metal cover attached, but this is intended to hide the rust of the steel wheel and could not be called a design.
In addition, because the wheel cap is fitted using the frictional force of the leaf spring, it may come off due to an impact caused by running on uneven terrain, which may put the following vehicle in danger.

There are various types of vehicles, and power sources include internal combustion engines and electric motors. Naturally, there are a variety of functions required for wheels, but existing technologies satisfy all of these requirements. It was impossible to do.

It is an object of the present invention to easily solve all the following problems at low cost.
1. The design of the wheel can be changed without detaching the wheel from the vehicle.
2. In a quiet vehicle such as an electric vehicle, a sound is generated to inform the pedestrian of the approach of the vehicle.
3. Force the wind to the brake disc in the wheel.
4. Continue to generate sound and wind for a certain time after the vehicle stops.
5. Change the strength of sound and wind according to the running speed.
6. Stop the generation of sound and wind according to the running speed.
7. Balance the wheel without using the balance weight.
8. Generates power with inertial force even after the vehicle stops. Moreover, a sound is generated with the electric power.

When the wheel is attached to the vehicle, a decorative plate is detachably mounted on the outer surface that can be best seen, and the design of the decorative plate can be changed to change the design of the entire wheel.

The decorative plate is provided with through-holes and whistles to generate sound, and a wing shape is provided to forcibly send wind to the brake disc in the wheel to cool the heated brake disc. In addition, by changing the size and shape of the whistle and wing or providing a plurality of specifications, it is possible to generate sound and wind only at a predetermined rotational speed.

According to the present invention, the design of the wheel can be changed without removing the wheel itself from the vehicle, and the convenience is greatly improved.
In addition, not only the design but also the sound and cooling air can be generated according to the characteristics of the vehicle, which can contribute to industrial development widely.

FIG. 3 is a cross-sectional view of the present invention in which a rim, a disk, and a decorative wheel are integrated with a through bolt. 1 to 8 are schematic diagrams for explaining the function of the present invention. It is a front view of FIG. 1, and represents the design surface (outer surface) of a wheel. The rim and the disk are integrated with a through bolt, and the cross section of the present invention is shown in which the disk and the decorative wheel are integrated with a through bolt. still, It is a front view of FIG. 3, and represents the design surface (outer surface) of a wheel. FIG. 3 is a cross-sectional view of the present invention in which the rim is separated into left and right parts and flute and wings are provided on a decorative plate in the configuration of FIG. It is a front view of FIG. 5, and represents the design surface (outer surface) of the wheel. FIG. 3 is a cross-sectional view of the present invention in which the outer peripheral portion of the decorative plate is rotatably held by a roller provided on the disc so that the disc and the decorative plate can be rotated relative to each other. It is a front view of FIG. 7, and represents the design surface (outer surface) of the wheel.

An embodiment for carrying out the present invention and solving all the above-mentioned problems is as detailed in claims 1 to 4, and an example thereof will be described with reference to the drawings.

1 and 2 show a wheel equipped with the decorative plate of the present invention. FIG. 1 is a sectional view and FIG. 2 is a front view. In a typical wheel, a disc 2 is mounted on a rim 1 and fastened to a hub attached to an axle through a through hole 4. Further, the axle and the rotation center are aligned with the through hole 6 at the center of the disk as a guide.
However, with this configuration, the design of the wheel cannot be easily changed. Therefore, if the decorative plate 3 is fastened together with the bolt 5 and the decorative plate is used as a design surface, the design can be easily changed while minimizing an increase in cost. Since the rim 1 is provided with a female screw 22, it can be fastened with a bolt. The above is the embodiment of the present invention described in claim 1.

3 and 4 show a wheel equipped with the decorative plate of the present invention. FIG. 3 is a sectional view and FIG. 4 is a front view. In FIG. 1, the decorative plate 3 is fastened together with the rim and the disk, but the decorative plate cannot be easily replaced. Therefore, as shown in FIGS. 3 and 4, only the rim 1 and the disk 7 are fastened with the bolts 9, and the decorative plate 8 is attached to the disk 7 with the bolts 10. With this configuration, the decoration plate can be exchanged even when the wheel is attached to the vehicle. Since the disk 7 has a female screw 23, it can be detachably fastened with a bolt. The above is the embodiment of the present invention described in claim 2.

5 and 6 show a wheel equipped with the decorative plate of the present invention. FIG. 5 is a sectional view and FIG. 6 is a front view. The decoration plate 14 is attached to the disk 13 with bolts 10 as in FIG. 3, but since the whistle 15 is attached to the decoration plate, sound is generated by the air flow caused by the rotation of the wheel.
Further, by adjusting the size and shape of the whistle, it is possible to set so that sound is generated only at a predetermined rotational speed and no sound is generated in other rotational speed ranges. In addition, 11 and 12 show the right-and-left division type rim | limbs, and represent the structure of what is called a 3 piece wheel fastened with the volt | bolt 9 using the internal thread 24. FIG.

Reference numeral 16 denotes a wing provided on the decorative plate 14, which is formed by cutting out a part of the decorative plate and bending it. If a through hole is provided in the vicinity of the portion of the disk 13 where the wing 16 contacts, the wing generates wind by the rotation of the wheel, and air is passed through the through hole of the disk to the inside of the wheel, that is, the left side of FIG. I can send it. In FIG. 5, when there is a part that generates heat, such as a brake disk, on the left side of the disk 13, the cooling air can be sent as described above. The above is the embodiment of the present invention described in claim 3.

7 and 8 show a wheel equipped with the decorative plate of the present invention. FIG. 7 is a sectional view and FIG. 8 is a front view. Although the above-described decorative plate is fixed to the wheel, in this configuration, the decorative plate 18 is held rotatably with respect to the wheel. The bolt 21 that fastens the rim 1 and the disk 17 together is fastened by a female screw 22 provided on the rim. At this time, a roller 19 and a washer 20 are interposed. With this configuration, the decorative plate 18 can be freely rotated without being removed by the washer, with its outer periphery held by the roller. If the bolt has a stepped bolt or has a double structure with inner and outer cylinders, the roller can rotate freely even when the bolt 21 is tightened, and the roller may be changed to a bearing. With this structure, even after the vehicle stops and the wheel stops rotating, the decorative plate rotates for a certain period of time due to the inertial force of the decorative plate 18, so that it is possible to continue generating sound and wind. . The above is the embodiment of the present invention described in claim 4.
