The invention relates to a wheel decoration cover, a wheel assembly and a vehicle. The wheel decoration cover comprises a circular cover body. The cover body is provided with a plurality of ventilation holes formed in the circumferential direction of the cover body at intervals, and the side, facing the outside of a vehicle, of each ventilation hole is covered with a rectification structure. The side wall, facing the circle center of the cover body, of the rectification structure and the cover body are spaced to form rectification holes. The other side walls of the rectification structure are in sealed connection with the hole walls of the corresponding ventilation holes. The rectification holes are perpendicular to the radial direction of the cover body, the corresponding rectification holes, the rectification structure inner cavities and the ventilation holes jointly define rectification channels arranged in the radial direction of the cover body, and when wheels run, airflow flows out of the rectification holes located in the leeward side and flows in of the rectification holes located in the windward side. The direction of airflow flowing in or out of the wheel trim cover is basically parallel to the incoming flow direction in front, the flowing direction of the airflow is controlled in order, the phenomena of turbulent flow and turbulent flow around a wheel are avoided to a certain extent, the wind resistance of the wheel is reduced, and the resistance reduction effect of the wheel trim cover is improved.

    本公开涉及一种轮饰盖、车轮组件及车辆,轮饰盖包括圆形的盖本体;盖本体上开设有沿盖本体的周向间隔设置的多个通风孔,各通风孔朝向车外的一侧分别罩设有整流结构;整流结构朝向盖本体圆心一侧的侧壁与盖本体间隔形成整流孔,整流结构其它侧壁与对应的通风孔孔壁密封连接;整流孔与盖本体的径向垂直,对应的整流孔、整流结构内腔、通风孔共同限定出沿盖本体的径向布置的整流通道,车轮行驶时气流从位于背风侧的整流孔中流出,从位于迎风侧的整流孔中流入,从轮饰盖流入或流出的气流方向与前方的来流方向基本平行,有序控制了气流的流动方向,在一定程度上避免了在车轮周围产生乱流、紊流的现象,降低了车轮风阻,提升了轮饰盖的减阻效果。
