Patent 11691662 was granted and assigned to Oshkosh Corporation on July, 2023 by the United States Patent and Trademark Office.
A steering system includes a first wheel and a second wheel spaced apart from the first wheel, a first tie rod, a second tie rod, and an electrical actuator. The first wheel is rotatably coupled to a first knuckle, and the first knuckle is pivotable about a first suspension post. The second wheel is rotatably coupled to a second knuckle, and the second knuckle is pivotable about a second suspension post spaced apart from the first suspension post. The first tie rod is coupled to the first knuckle and to a mechanical linkage. The second tie rod is coupled to the second knuckle and the mechanical linkage. The electrical actuator is coupled to the mechanical linkage so that movement of the electrical actuator translates the mechanical linkage axially, which adjusts the orientation of the wheels relative to the suspension posts.
