Patent number: 11021187Abstract: A steering knuckle is used in a motor vehicle and is typically positioned adjacent a front wheel thereof. The steering knuckle includes a central portion, a steering knuckle arm, an upper portion and a lower portion. The steering knuckle arm, the upper portion and the lower portion may each be contoured with full or partial roulette contoured surfaces (i.e., surfaces defined by roulette curves), and the upper portion may transition from a hollow lower portion to a solid upper portion defining an I-beam. A dual-beam horizontal support is formed in the central portion. The steering knuckle is formed from a casting process, and the roulette curvature of the steering knuckle arm, the upper portion and the lower portion provide draft to the surfaces of the steering knuckle which are perpendicular to the parting line of the casting mold, allowing the steering knuckle to be easily removed from the casting mold.Type: GrantFiled: May 1, 2018Date of Patent: June 1, 2021Assignee: ILJIN USA CorporationInventors: Ron J. Johnson, Jeremy S. Mercer
