Problems solved by technology

[0015] However, since the automobile wheel disclosed in Patent Document 1 has a U-shaped arm, although the lateral rigidity is definitely improved, its longitudinal rigidity is insufficient.
In addition, although this document also discloses an automobile wheel with a W-shaped arm, since the part inside the connecting part with the bead seat part is too large, it may collide with the suspension, and it is composed of a composite material of synthetic resin. so not practical
[0016] In the rim for a wheel disclosed in Patent Document 2, since it cannot be integrally formed even if it is bent, it is difficult to say that the rigidity of the rim is sufficiently improved.
[0017] The vehicle wheel disclosed in Patent Document 3 has excellent longitudinal rigidity, but insufficient lateral rigidity.

Abstract

Disclosed is a wheel made of lightweight alloy having superior rigidity in the vertical and horizontal directions. A wheel made of lightweight alloy (10) for use with vehicles comprises a disc portion (6); and an inner rim portion (8) arranged in a standing state upon the rim of the disc portion (6). The inner rim portion (8) further comprises a well portion (11) arranged in a standing state vertically upon the rim of the disc portion (6); a rim center portion (12) that is serially connected to the well portion (11); and an inner rim flange portion (13) that is connected to a connecting portion (15) of the leading edge of the rim center portion (12). The inner rim flange portion (13) further comprises a perimeter flange (13a), which extends outward from the connecting portion (15); and an inner circumference flange (13b), which extends inward from the connecting portion (15). The edge of the perimeter flange (13a) curves in the axial direction.

Description

technical field [0001] The invention relates to a light alloy wheel which strengthens the rim and improves the rigidity. Background technique [0002] Vehicles traveling on the road generally have metal wheels on which tires are mounted and which support the tires. [0003] In recent years, wheels that are as light as possible and offer great designability have been favored. Especially in passenger vehicles, the diameter of wheels is increasing day by day in order to reduce vibration during driving and improve maneuverability. [0004] However, as the diameter of the wheel increases, the substantially cylindrical inner rim tends to warp. [0005] For such defects, some studies have proposed a method of strengthening the inner rim flange of the inner rim. [0006] For example, there is known an automobile wheel whose rim has a bead holding flange made of a composite material having a U-shaped cavity extending along the entire circumference of the rim (for example, refer to...
