The invention discloses an automobile hub capable of reducing wind resistance, and relates to the technical field of automobile hubs, the automobile hub comprises a hub body, the hub body comprises a rim, a wheel disc and spokes, a sealing part is arranged in the rim, the sealing part is arranged on the outer side of the wheel disc, and the sealing part is used for sealing a cavity of the rim to reduce the wind resistance of the rim during running. The sealing piece comprises an outer plate and an inner plate, and the outer plate is fixed to the outer side of the spoke. The invention aims to solve the problems that in the prior art, a cavity of an automobile hub is generally open, but the open hub cavity can be impacted by airflow when an automobile runs at a high speed, an internal cavity can form vortex or turbulent flow, aerodynamic resistance is increased, energy consumption is increased and the like. Compared with the prior art, the wheel hub has the advantages that the sealing piece capable of being opened and closed is arranged on the surface of the wheel hub, so that the sealing piece can seal the cavity and reduce aerodynamic resistance during high-speed driving, and the sealing piece can be opened and improve heat dissipation during braking.

    本发明公开了一种可减小风阻的汽车轮毂,涉及汽车轮毂技术领域,包括轮毂本体,轮毂本体包括轮圈、轮盘和轮辐,所述轮圈内部设置有封闭件,所述封闭件设置在轮盘外侧,封闭件用于将轮圈的空腔进行封闭降低其行驶的风阻,所述封闭件包括外板、内板,所述外板固定于轮辐的外侧。本发明针对现有技术中汽车轮毂的空腔一般都是开放式,但开放式的轮毂空腔会在车辆高速行驶时会受到气流冲击,内部空腔会形成涡流或湍流,增加气动阻力,增加能耗等问题进行改进。本发明具有通过在轮毂表面设置有可进行启闭的封闭件,使得在高速行驶时,封闭件可以对空腔进行封闭,降低气动阻力,而在刹车时,封闭件可以开启,提高散热等优点。
