  • Wheel having spokes with V-shaped cross-sections
    Patent number: 6913323
    Abstract: A wheel for a motor vehicle has a wheel hub connected with a wheel rim by spokes. In order to create a wheel for a motor vehicle which has low weight and high stability, spokes arranged between the wheel hub and the rim are constructed such that, in first areas connected with the wheel hub, the spokes have solid cross-sections and, in second areas connected with the rim, the spokes have V-shaped cross-sections. Transitions between the two areas are progressive; that is, along a longitudinal course of each spoke from the wheel hub toward the rim, the cross-section of a spoke is changed from an initially solid cross-section, which preferably has an elliptical construction, to a triangular cross-section, which then further changes to a V-shaped cross-section while forming a groove arranged in its center.
