The invention relates to a wheel decoration cover, a wheel assembly and a vehicle. The wheel decoration cover comprises a wheel decoration cover body. The wheel trim cover body protrudes in the direction away from a wheel to form a curved surface, a connecting structure used for detachably connecting the wheel trim cover body to the wheel is arranged on the face, facing the wheel, of the wheel trim cover body, the maximum chord length of the curved surface is c, the distance between the maximum protruding height of the curved surface and the outer edge of the same side of the wheel trim cover body is X, and the relation between c and X meets the condition that X/c is larger than or equal to 0.2 and smaller than or equal to 0.5. The relation between the maximum protruding height t of the curved surface and the width W of the tire meets the condition that t/W is larger than or equal to 0.1 and smaller than or equal to 0.5, when the connecting structure and the wheel are connected in place, the outer edge of the opening end of the curved surface is located between the face, facing the outside of the vehicle, of the tire and a rim of the wheel, and the smooth streamline-shaped curved surface has the good aerodynamic configuration and the low wind resistance coefficient; air resistance borne by the wheel in the running process is reduced, the wind resistance coefficient and wind resistance of the wheel are reduced, and the pneumatic resistance reduction effect is improved.
本公开涉及一种轮饰盖、车轮组件及车辆,轮饰盖包括轮饰盖本体;轮饰盖本体朝向远离车轮的方向凸出成为曲面,轮饰盖本体朝向车轮的一面设有用于将轮饰盖本体可拆卸连接在车轮上的连接结构,曲面的最大弦长为c,曲面的最大凸出高度与轮饰盖本体同侧外缘之间的距离为X,c和X的关系满足0.2≤X/c≤0.5,曲面的最大凸出高度t和轮胎的宽度W的关系满足0.1≤t/W≤0.5,连接结构与车轮连接到位时,曲面的开口端外缘位于轮胎朝向车外的一面和车轮的轮辋之间,平滑流畅的流线形曲面具有较好的气动外形和较低的风阻系数,减少了车轮在行驶过程中所受到的空气阻力,降低了车轮的风阻系数和风阻力,提升了气动减阻效果。
