The invention provides a spherical shell part of an automobile chassis. The spherical shell part is mainly formed by connecting a first connection plate arm and a second connection plate arm through a middle connection convex column in an L shape, wherein a first connection convex column and a second connection convex column are arranged at respective outer end parts of the first connection plate arm and the second connection plate arm respectively; the first connection plate arm and the second connection plate arm form arc-shaped bent arms respectively; after the first connection plate arm and the second connection plate arm are connected through the middle connection convex column, a transitional continuous arc-shaped inner edge is formed on the inner edge, and a transitional continuous arc-shaped outer edge is formed on the outer edge; convex ribs are formed on the front and back surfaces of the first connection plate arm and the second connection plate arm by the arc-shaped inner edge and the arc-shaped outer edge respectively; the two ends of the convex ribs of the arc-shaped inner edge and the arc-shaped outer edge are connected onto the corresponding edges of the first connection convex column and the second connection convex column respectively; and at least one concave plane formed by enclosing of convex bars is arranged on each of the front and back surfaces of the first connection plate arm and the second connection plate arm.
