  • Light alloy cast wheel
    Patent number: 5292182
    Abstract: A light allow cast wheel includes a disk portion and a rim portion integral with the disk portion. The rim portion includes a first flange located closer to the disk portion and a second flange located farther from the disk portion. The second flange includes a radially extending portion which has an outboard surface and an inboard surface. The second flange has a plurality of grooves recessed from the outboard surface of the radially extending portion. Since a thickness of the second flange is reduced due to the grooves, a thermal thickness shrinkage of the second flange which occurs during casting is small. As a result, generation of blow holes in the second flange during casting is prevented.
