A wheel casing includes: a central portion including a planar surface; a first arcuate portion surrounding the central portion and including a first arcuate surface having a first radius of curvature; and a second arcuate portion surrounding the first arcuate portion and including a second arcuate surface having a second radius of curvature. The second radius of curvature is different from the first radius of curvature. The planar surface, the first arcuate surface, and the second arcuate surface form a continuous and uninterrupted outer surface from a center of the wheel casing to an outermost peripheral edge of the wheel casing.
一种轮罩包括:中心部分,所述中心部分包括平面表面;第一弓形部分,所述第一弓形部分包围所述中心部分且包括具有第一曲率半径的第一弓形表面;以及第二弓形部分,所述第二弓形部分包围所述第一弓形部分且包括具有第二曲率半径的第二弓形表面。所述第二曲率半径不同于所述第一曲率半径。所述平面表面、所述第一弓形表面和所述第二弓形表面从所述轮罩的中心到所述轮罩的最外周边边缘形成连续且不间断的外表面。
