この発明は、車両用ホイール（以下、ホイール
という）に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a vehicle wheel (hereinafter referred to as a wheel).
近年自動車のF.F.（前輪駆動）化に伴い、ホイ
ールもオフセツトの大きいものが多く装着される
ようになつてきた。
In recent years, with the shift to front-wheel drive (FF) automobiles, many wheels with large offsets have been installed.
従つて、このようなホイールはデイスクをホイ
ールの表側に突出させた形状となるため、リムと
デイスクとの接合部が肉厚部とならざるを得なか
つた。そのためホイール全体の重量が増加するこ
ととなり、操縦性能の低下や燃費の増加に影響を
及ぼすものであつた。 Therefore, since such a wheel has a shape in which the disk protrudes from the front side of the wheel, the joint between the rim and the disk must be a thick portion. This resulted in an increase in the weight of the entire wheel, which had an impact on a decrease in maneuverability and an increase in fuel consumption.
そこで従来のホイールは、第１図に示すよう
に、ホイール１のリム２とデイスク３との接合部
４であつてリム内周面５側に凹状の空間部６が形
成されたものであつた。 Therefore, in the conventional wheel, as shown in FIG. 1, a concave space 6 was formed at the joint 4 between the rim 2 and the disk 3 of the wheel 1 on the rim inner peripheral surface 5 side. .
しかし、このようなホイールは、その空間部６

ツトスポツトとなるため、クサレ等の鋳造欠陥が
発生し易く、ホイールの強度低下、空気漏れの原
因となつていた。 However, such a wheel has a space 6
When forming by casting, as shown in FIG. 2, a core 8 is placed at a position corresponding to the joint 4 of the upper mold 7 that forms the inner circumferential surface 5 of the rim. Because the heat retaining effect of the core 8 causes the joint 4 to become a hot spot, casting defects such as cracks are likely to occur, resulting in a decrease in the strength of the wheel and air leakage.
この発明は、このような欠点を解決するために

The present invention has been made to solve these drawbacks, and has a structure in which a disk and a rim are integrally cast, and a molten metal removal member is disposed in the circumferential direction at a portion of the rim that is connected to the disk. The vehicle wheel is integrally cast in a state in which the molten metal removal member has a C-shaped cross section and an opening thereof is exposed on the back surface of the rim.
以下、図面に基づいてこの発明の実施例を説明

部まで延設される結果、広く採ることできる。 The one shown in FIG. 3 is a cast wheel made of aluminum alloy, and on the rim inner peripheral surface 5 side of the wheel 1, inside the joint 4 between the rim 2 and the disk 3, there is a cross-section C made of aluminum alloy. This is a ring-shaped molten metal removal member 9 that is cast inside, and its opening is exposed to the inner circumferential surface 5 of the rim. The C-shaped tip 19 of the molten metal removing member 9 is maintained flush with the rim inner circumferential surface 5. Therefore, since the wheel interior space extends to the inside of the molten metal removal member 9, it can be made wide.
次に、第３図に示された鋳造製ホイールの製造
方法を第４図に基づいて説明する。 Next, a method for manufacturing the cast wheel shown in FIG. 3 will be explained based on FIG. 4.

い）を形成させても良い。 The mold is made up of four metal molds. On the lower mold 13 that forms the disk surface side 12 of the wheel 1, on the rim outer peripheral surface 14 of the wheel 1.
Two horizontal molds 15, 15 for forming the rim are slidably opposed to each other, and an upper mold 7 for forming the inner peripheral surface 5 of the rim and the back side 16 of the disc is placed on the horizontal molds 15, 15. . first,
As shown by the two-dot chain line, the upper mold 7 is raised, and the cross section C
A molten metal expulsion member 9 made of aluminum alloy and formed into a ring shape is fitted into the mold with its C-shaped tip 19 in contact with the molten metal expulsion member 9, and the molten metal expulsion member 9 is lowered while being held by the upper mold 7. , molten aluminum alloy is poured into the casting space 18 of the wheel by matching the molds as shown by solid lines in the drawings. Thereafter, after waiting for the molten metal to solidify, the upper mold 7 and the horizontal molds 15, 15 are moved upward and horizontally to take out the wheel 1 from the mold.As described above, the rim 2 of the wheel 1 is removed.
A molten metal removal member 9 is installed inside the joint 4 of the disk 3.
The C-shaped tip 19 (of the molten metal removal member 9) is exposed flush with the inner peripheral surface of the rim. In addition, a molten metal removal member 9 is attached to the upper mold 7.
In order to make it easier to hold the upper die 7, a small protrusion (not shown) may be formed on the outer periphery 17 of the disk side tip.
また、溶湯排除部材９はリング状に形成したも

A vehicle wheel according to the present invention is a vehicle wheel in which a disk and a rim are integrally cast, and a molten metal removal member is disposed in the circumferential direction at a portion of the rim that is connected to the disk. , Since the molten metal removal member has a C-shaped cross section and its opening is exposed on the back surface of the rim, it is possible to prevent casting defects such as curls that occur in conventional cast wheels, and to reduce the space inside the wheel. It can be extended to the deep part of the inner peripheral surface of the part, and as a result, it is easy to install large brakes, which have been in increasing demand in recent years.
