  • Vehicle wheel disk and a manufacturing method thereof
    Patent number: 9511623
    Abstract: A vehicle wheel disk and a manufacturing method thereof is provided. The vehicle wheel disk is manufactured from a disk material of a flat plate. The vehicle wheel disk includes a hub coupling portion, a disk flange and a hat. The hat includes a hat top protruding outwardly in an axial direction of the disk, a radially inner hat portion connecting the hat top and the hub coupling portion, and a radially outer hat portion connecting the hat top and the disk flange. In the vehicle wheel disk, a first thickness-reduced portion is smaller in thickness than the disk material that is formed at the radially outer hat portion.
    Type: Grant

  • Lightened disk for a wheel and a method for manufacturing the same
    Patent number: 6839967
    Abstract: A lightened disk for a wheel has a flange having an axially inboard edge. The inboard edge includes a general portion which is located in a plane perpendicular to an axis of the disk. The flange portion has a thickness less than 90% of a thickness of a disk material at at least the general portion of the inboard edge. A method for manufacturing a lightened disk for a wheel includes a drawing step during which the flange portion is drawn such than the flange portion has a thickness less than 90% of a thickness of a disk material at at least the general portion of the inboard edge.
