Definitions
- the present invention relates to a tire wheel rim that is useful for lowering the temperature of a mounted tire and improving the durability of the tire or the wheel itself.
- the tire bead portion undergoes large and repeated deformation during running. For this reason, the temperature of the bead part during driving rises. Such a temperature rise causes rubber deterioration of the bead portion and sometimes breaks. Therefore, in order to improve the durability of the tire, it is necessary to prevent the temperature of the bead portion from increasing.
- the present invention has been devised in view of the above circumstances, and provides a wheel rim for a tire that is useful for suppressing the temperature rise of a mounted tire or wheel itself and improving the durability of the tire or wheel.

And a convex portion extending in a direction crossing the circumferential direction on the outer surface in the rotational axis direction of the flange and / or the inner surface in the radial direction of the rim body that does not contact the tire. It is characterized by being spaced apart in the direction.
- convex portions extending in a direction crossing the circumferential direction are provided in the circumferential direction on the outer surface of the flange that does not contact the tire and / or the inner surface of the rim body.
- a convex part increases the surface area of a rim
- the convex portion disturbs the air flowing on the surface of the rim portion by the rotation of the wheel rim, generates a turbulent flow, and further improves heat dissipation.
- FIG. 1 is an overall perspective view of a tire / rim assembly showing an embodiment of the present invention. It is the fragmentary sectional view. It is an expanded view of the inner surface of the rim
- FIG. It is a diagram which shows the air flow by a fluid analysis. It is an expanded view of the inner surface of the rim

- FIG. 2 shows a partial cross-sectional view thereof.
- the pneumatic tire 2 includes a tread portion 2a, a pair of sidewall portions 2b and 2b extending inward in the tire radial direction from both ends thereof, and a pair of bead portions 2c and 2c provided at the inner ends thereof.
- a tubeless type radial tire for a passenger car having the following is shown.
- the pneumatic tire 2 includes a radial carcass 2e extending in a toroidal manner between the bead cores 2d and 2d embedded in the bead portion 2c, a belt layer 2f disposed outside the tire radial direction and inside the tread portion 2a, and including.

And a groove-shaped well portion 5b extending in the circumferential direction with a depth and width for dropping the bead portion 2c.
- the flange 6 extends at a small height outward in the tire width direction along the outer surface in the tire axial direction of the bead portion 2c of the pneumatic tire 2 attached to the seat portion 5a.
- Such a rim portion 1A is formed in a cylindrical shape having substantially the same cross-sectional shape and continuous in the circumferential direction.
- the disk portion 1B is composed of a plurality of (five in this embodiment) spokes extending inward in the tire radial direction from the inner peripheral surface of the rim portion 1A.
- the disk portion 1B may literally be configured in a disc shape.
- FIG. 3 shows a developed view of the inner surface of the rim portion 1A.

- a plurality of convex portions 9 extending in a direction crossing the direction are provided in the circumferential direction.
- Such a convex portion 9 increases the heat dissipation of the rim portion 1A by increasing the surface area of the rim portion 1A. Furthermore, as a result of various experiments by the inventors, as shown in FIG. 5, the convex portion 9 disturbs the air flowing on the surface of the rim portion 1A generated by the rotation of the tire / rim assembly 3 to generate turbulent flow. It was found that this turbulent flow effectively removes heat from the rim portion 1A. That is, the air in contact with the surface of the rim is the hottest temperature, and the air temperature decreases as the distance from the rim surface increases, but the turbulent flow leads to the high temperature layer by guiding the low temperature air away from the rim surface to the rim surface. Therefore, the surface temperature of the rim can be efficiently reduced.
- the wheel rim 1 of the present embodiment is efficiently cooled by the convex portion 9 during traveling.
- the heat of the air filled in the bead portion 2c of the tire 2 and the tire lumen i in contact with the wheel rim 1 is efficiently released to the outside through the rim portion 1A having excellent heat dissipation. .

- the convex portion 9 having such a rectangular cross section helps to effectively dissipate the air passing through the vicinity of the inner surface of the rim portion 1A and enhance the heat dissipation.
- the cross-sectional area perpendicular to the longitudinal direction of the convex portion 9 is not particularly limited, but if it is too small, the increase in the surface area of the wheel rim 1 is small, and as a result, the cooling effect may not be sufficiently obtained. If it is too large, it causes an excessive increase in the rim mass, which is not preferable.

There is a possibility that the heat dissipation of the rim 1 may not be sufficiently increased. Conversely, if it is excessively small, the surface of the rim portion is not sufficiently exposed to air between the convex portions 9 and 9, and the heat dissipation may be reduced. From such a viewpoint, the arrangement pitch P of the protrusions 9 is preferably 60 degrees or less, more preferably 12 degrees or less, and more preferably 12 degrees or less when represented by a center angle (center angle centered on the rotation center of the wheel rim).

図1には、第1の実施形態のタイヤ用ホイールリム(以下、単に「ホイールリム」ということがある。)1に空気入りタイヤ2を装着したタイヤ・リム組立体3の全体斜視図が示される。また、図2には、その部分断面図が示される。
上記第1の実施形態では、いずれも凸部9がリム部1Aの実質的に外側領域A1だけに設けられていた。しかし、図9に示されるように、凸部9は、リム部1Aの内側面のうち、実質的に一対のシート部5a、5a間の中央領域A2だけをのびるように設けられても良い。
さらに、凸部9は、図14に示されるように、リム部1Aの実質的に全域(即ち、外側領域A1及び中央領域A2)をのびるように設けられても良い。このような実施形態の凸部9は、リム部1Aの全体を効果的に冷却できる。従って、ビード部2cのみならず、タイヤ内腔iに充填された空気の昇温をより確実に防止し、ビード部2cのゴム部の温度上昇を抑制して耐久性を向上させることができる。
リムの重量バランス、均一性などを考慮すると、上記各実施形態のように、前記凸部9は、周方向に一定の配設ピッチPで設けられるのが望ましい。しかしながら、凸部9が一定の配設ピッチPで設けられた場合、凸部9の大きさ及び/又は断面形状等によっては(例えば、凸部9を大型化した場合)、各凸部9で生じる特定周波数の風切り音が互いに重畳し、車両の乗員に耳障りな異音を感じさせるおそれがある。
図19(a)、(b)には、リム部の周方向に沿った断面の展開図を示している。この実施形態では、周方向に隔設された凸部9は、断面形状が異なる複数種類が周方向に隔設されている。この例では、凸部9は、第1の凸部9Aと、この第1の凸部9Aよりも高さH及び幅Wが大きい第2の凸部9Bとを含んでいる。これらは、同図(a)のように一定の配設ピッチPで隔設されても良いし、同図(b)のように、非一定の配設ピッチで隔設されても良い。このような実施形態でも、特定周波数の風切り音の重畳を防止して、耳障りな異音の発生を減らすことができる。
