The invention belongs to the technical field of automobiles, and particularly relates to an automobile wheel cover lining plate capable of reducing wind resistance, which comprises a lining plate body which is mounted on an automobile body and covers a tire, the lining plate body is of an arc-shaped convex bulge structure, and an outer side plate is fixedly arranged on the outer side of the lining plate body; the contour line of the upper edge of the lining plate body is located below the contour line of the upper edge of the outer side plate, the distance L1 between the inner wall of the front side of the lining plate body and a tire is 10-35 mm, the distance L2 between the inner wall of the rear side of the lining plate body and the tire is 10-35 mm, and under the full load condition, the distance L2 between the inner wall of the top of the lining plate body and the tire is 10-35 mm. The wheel cover lining plate is divided into the lining plate body, the outer side plate and the inner side plate, and the shape of the lining plate body is changed under the conditions that the size of the outer side plate is not changed and the matching of the wheel cover lining plate and a wheel eyebrow is not influenced, so that the shape of a cavity between the wheel cover lining plate and a tire is optimized, the turbulence of a wheel cavity is reduced, and the service life of the wheel cover lining plate is prolonged. And the effect of reducing the wind resistance is further achieved.

    本发明属于汽车技术领域,具体涉及一种降低风阻的汽车轮罩衬板,包括安装在车体上、且罩设在轮胎上方的衬板本体,衬板本体为弧形的凸起鼓包结构,衬板本体的外侧固定设有外侧板,衬板本体上部边缘的轮廓线位于外侧板上部边缘的轮廓线下方,衬板本体的前侧内壁与轮胎之间的距离尺寸L1为10mm‑35mm,衬板本体的后侧内壁与轮胎之间的距离尺寸L2为10mm‑35mm,在满载情况下,衬板本体的顶部内壁与轮胎之间的距离尺寸L2为10mm‑35mm。其目的是:通过把轮罩衬板分为衬板本体、外侧板和内侧板,在外侧板尺寸不变,不影响轮罩衬板与轮眉造型的匹配的情况下,对衬板本体的形状进行更改,使得轮罩衬板与轮胎之间的空腔形状得到优化,轮腔乱流减少,进而起到降低风阻的效果。
