Title:
WHEEL RIM FLANGE CROWN
Document Type and Number:
WIPO Patent Application WO2001087645
Kind Code:
A3
Abstract:
A wheel (11) having a rim (12) with a pair of flanges (17, 19) including a peripheral potential roll surface (33) on at least one flange for contacting the ground in the event of tire failure has a convexly contoured roll surface with a finite cross-sectional radius of curvature (42) at the outermost radius of the wheel to provide an optimized shape of the contact surface and an enhanced contact area without introducing any flat regions in the contact area. The roll surface is formed to have a finite radius of curvature throughout the potential roll surface. The roll surface radius of curvature and may be formed in cross-section as a central circular segment (40) blending smoothly into two circular segments (44, 50) of lesser radii at the central circular segment extremities, or may be formed in cross-section as a portion of an ellipse (57) having a semi-minor axis (63) extending generally radially along the respective annular rim portion.
