Abstract
A lightweight wheel spoke for an automobile increases the strength around the heat dissipation holes by thickening the material around the heat dissipation hole on the inner wall of the spoke. The thinning of the material between the heat dissipation holes, that is where there is no heat dissipation holes on the tapered barrel, enables the tapered barrel of the spoke to form a unique concave-convex structure on the inner wall or the outer wall, thereby enabling the entire spoke to be secured.
Claims7
A wheel disc with thickened edges around heat dissipation holes, comprising:
- a mounting surface, and
- a tapered barrel, wherein:
- two opposite ends of the tapered barrel respectively comprise a first opening and a second opening,
- the mounting surface is disposed on the first opening of the tapered barrel,
- the heat dissipation holes penetrate a side wall of the tapered barrel,
- axes of the heat dissipation holes are perpendicular to the tapered barrel,
- portions of the tapered barrel disposed around the heat dissipation holes protrude to define a plurality of protruding portions in a thickness direction of the tapered barrel,
- every two adjacent protruding portions of the plurality of protruding portions are separated to define a concave portion, and
- the concave portion is gradually enlarged in a radial direction of the wheel disc extending towards the second opening.
