Title:
WHEEL DISC FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/153577
Kind Code:
A1
Abstract:
Provided is a wheel disc for a vehicle equipped with a spoke part (15) comprises a spoke top wall (15a), a spoke peripheral side wall (15b), and a pair of spoke circumferential direction side walls (15c). Moreover, a top wall peripheral side bent part (15a2) of the spoke top wall (15a) curves in the disc radial section of the spoke part (15), with a larger curvature than the curvature of a top wall inner circumference bent part (15a1) of the spoke top wall (15), a top wall stating part (15a4) of the spoke top wall (15), and the spoke peripheral side wall (15b). Therefore, the shape of the spoke part (15) approaches more easily the shape of a box as compared with the conventional technology, and as a result, it is possible to improve the bending strength and flexural rigidity of the spoke part (15) in the disc radial direction.
