Problems solved by technology

[0004] However, this existing vehicle wheel has a problem
That is, there is a problem that, in a wheel in which the vertical wall is formed so as to stand up from the wheel well, it is necessary to combine a plurality of bulkheads and cover members with high precision by welding, bonding, embedding, and coupling in order to maintain airtightness. , when consideration is given to airtightness assurance, manufacturing man-hours, and increased manufacturing costs, it is not suitable for mass production
[0006] However, in the case of using resin as a material, compared with the case of using metal, since the surface rigidity of the wall material constituting the sub-air chamber is lower, in the tire air chamber, the positive side and the negative side are generated by air column resonance. When the air pressure fluctuates sideways and alternately, the volume of the sub-air chamber slightly increases or decreases, and the sound-absorbing performance as a Helmholtz resonator may not be sufficiently obtained.
[0007] In this case, it is considered to increase the rigidity by increasing the thickness of the above-mentioned wall material, but when the wall thickness of the wall material increases, the weight of the sub-air chamber member increases, and the centrifugal force acting on the sub-air chamber member also increases. The members for fixing the sub-air chamber members to the wheel wells also need to increase in strength, resulting in heavier and heavier vehicle wheels.

Abstract

The present invention provides a vehicle wheel, wherein a sub air chamber (13C) is provided with a plurality of grooves (31) concavely facing the sub air chamber (SC) side and extending along wheel circumferential direction, and a plurality of grooves (32) concavely facing the sub air chamber (SC) side and extending along wheel width direction on a bottom plate (25a) of a sub air chamber component (13A), in addition, a fovea is formed locally from the bottom plate (25a) to an upper plate (25b), and an upper butt-jointing portion (binding portion) (33A) is formed on several positions of the fovea bottom for jointing the bottom plate (25a) and the upper plate (25b). In the sub air chamber (13C) of the transfiguration embodiment, in the center of the wheel width direction, at least one of the bottom plate (25a) and the upper plate (25b) of the sub air chamber (13) is formed with grooves (31) in a direction crossed with a first longitudinal wall surface (15) and a second longitudinal wall surface (16) extending in a row along the circumferential direction of the wheel, and the butt-jointing portion (33A) is divided into eleven parts with equal interval.

Description

technical field [0001] The present invention relates to a vehicle wheel for reducing noise accompanying air column resonance (cavity resonance) in a tire air chamber. Background technique [0002] Vehicle wheels that reduce noise associated with air column resonance in a tire air chamber are known. Generally, air column resonance generated in an air chamber of a tire (hereinafter, referred to as a "tire air chamber") is a main cause of road noise of an automobile. Air column resonance is a phenomenon in which random vibration transmitted from the road surface to the tire causes the air in the tire air chamber to vibrate, resulting in a resonance phenomenon near the air column resonance frequency of the tire air chamber and resonance sound. [0003] (Japanese) Unexamined Patent Publication No. 2004-90669 discloses a vehicle wheel for reducing noise accompanying the air column resonance. This vehicle wheel has a plurality of sub-air chambers in the circumferential direction ...
