  • Motor vehicle wheel disc, in particular for a passenger vehicle
    Patent number: 7018000
    Abstract: Wheel disc, including a radially outer circular mounting part, a radially inner fixing and centering part with a bearing region comprising a specified number of fixing apertures and ending radially inwardly with a centering aperture, and spokes connecting the inner and outer parts. Each spoke is disposed substantially circumferentially between two adjacent fixing apertures and the radially inner free edges of the radially outer circular part defining perforations with the free lateral edges of the spokes. In order to mechanically reinforce each spoke, the central region of each spoke is deformed in order to house a swelling receding axially outwardly relative to the lateral regions of the spokes, including a yoke opening into the centering aperture.
