Abstract

PURPOSE:To facilitate the water drain in a wheel so as to prevent the balance of the wheel from being broken by providing a drain hole at the end of the wheel outer circumference side in a cavity of a monocoque spoke to have the water drained. CONSTITUTION:A drain hole 4 is provided on the back side in the direction of wheel rotation near the wheel outer circumference side end 3 in the cavity 2 of a monocoque spoke 1. And a dam 5 is provided from the wheel inner circumference back side of the hole 4, to the wheel outer circumference side of the cavity 2 of the spoke 1. In this constitution, the water in the cavity 2 is discharged from the barrier 5 as the wheel rotates. This causes the cavity to be well drained so as to prevent the balance of the wheel from being broken.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vehicle wheel having a structure in which water accumulated in cavities in spokes can be easily removed by rotation of the wheel while the vehicle is running. .

(Prior Art) Most vehicle wheels are made of light alloy in order to reduce weight. Furthermore, in order to reduce weight while maintaining strength, spokes with a monoconc structure and cavities opened toward the rim have appeared [Japanese Utility Model Publication No. 80-78601].

When the cavities of the spokes are open toward the disk, water accumulates in the cavities, so when using such a wheel, drain holes must be provided in the spokes.

However, water that accumulates in the cavities of such spokes collects on the outer circumference of the wheel due to centrifugal force as the wheel rotates, but even if drain holes are provided near the outer circumference, water does not drain smoothly from the drain holes. In this case, the amount of water accumulated in each spoke often differs, and the weight differs depending on each part of the wheel, causing the wheel to become unbalanced. This unbalanced wheel is dangerous when the vehicle is driven at high speeds.

(Problems to be Solved by the Invention) In view of the above-mentioned circumstances, the present invention provides a mono-hook type vehicle wheel that drains water accumulated in the cavities in the spokes while the wheel rotates while the vehicle is running. The object of the present invention is to obtain a vehicle wheel having a structure that allows the wheel to easily come off and prevent the wheel from becoming unbalanced.

(Means for Solving the Problems) The vehicle wheel of the present invention has a water drain hole at the outer peripheral end of the wheel in the monohook and spoke cavities of the vehicle wheel, and water flows out from the water drain hole. It is essential to have a structure that drains water, and as an embodiment, there is a drain hole on the rear side in the direction of rotation of the wheel, at a position near the outer edge of the wheel in the monohook and spoke cavity of the vehicle wheel. A weir is installed from the back of the water drain hole on the inner circumference of the wheel toward the outer circumference of the wheel in the spoke cavity, and the water collected in the spoke cavity collects on the outer circumference of the spoke as the wheel rotates, further forming a weir. Particularly preferred is a structure in which the water is drained out from the drainage hole along the .

Further, it is preferable that the shape of the spokes be slightly arched in the direction of rotation of the wheel, and that the portions attached to the outer circumferential portion of the wheel be located further in the rotation direction than the root portions of the wheel.

(Example) As shown in FIGS. 1 and 2, the vehicle wheel of the present invention basically has a water drain hole at the outer peripheral end of the monocoque and spoke cavities of the vehicle wheel. The structure is such that water is drained out from the drain hole.One example of this is as shown in Figures 1 and 2. A water drain hole (4
).

From the back of the water drain hole <4) on the inner circumference of the wheel toward the outer circumference of the wheel in the cavity of the spoke (1) <2)
t5+ is provided, and the water collected in the cavity (2) of the spoke fi+ collects on the outer circumference side of the spoke (1) as the wheel rotates, and then drains water along f[f51].
We created a structure in which the water is discharged from 41 to the outside.

(Function) Ice accumulated in the spoke cavities (2) gathers on the outer circumferential side of the wheel due to centrifugal force due to the rotation of the wheel. As the wheel rotates, water flows along the outer periphery of the wheel in the cavity (2) to the rear of the spokes (behind the rotational direction).There is a drainage hole here, from which the water is drained.

However, when the wheel rotates quickly, water flows in the axial direction of the wheel and beyond the drain hole. However, in an uninvented vehicle wheel, a weir is provided on the shaft side of the wheel of this water drain hole, and this weir stops the water.
It is ejected without entering the shaft any further.

(Effects of the Invention) The vehicle wheel of the present invention has a structure in which water drain holes are formed at the outer circumferential end of the wheel in the monohook and spoke cavities of the vehicle wheel, and water is discharged from the three drain holes. As an implementation example, a water drain hole is formed on the rear side in the direction of rotation of the wheel at a position near the outer circumferential end of the monohook and spoke cavity of the vehicle wheel, and the A weir is provided from the back of the inner circumference of the wheel in the extraction hole toward the outer circumference of the wheel in the spoke cavity, and as the wheel rotates, water collected in the spoke cavity collects on the outer circumference of the spoke and drains along the weir. Since it is particularly preferable to have a structure in which the water is discharged from the holes, in a monocoque type vehicle water ejector, the water accumulated in the cavities in the spokes can be drained from the water when the wheel rotates while the vehicle is running. The vehicle wheel of the present invention has the advantage of being easily removed and resistant to corrosion, as well as having a structure that does not disrupt the rotational balance of the wheel. Vehicles equipped with wheels are safe even when driving at high speeds, and therefore have the advantage of improving vehicle maneuverability, and the present invention greatly contributes to traffic safety and, ultimately, to the development of industry. be.
