Abstract
A steering system includes a first wheel and a second wheel laterally spaced apart from the first wheel, and a third wheel and a fourth wheel laterally spaced apart from the third wheel. The first wheel is rotatably coupled to a first knuckle and the second wheel is rotatably coupled to a second knuckle. The third wheel and the fourth wheel are both pivotally fixed in a forward-aligned orientation. The steering system includes a first tie rod having a first end pivotally coupled to the first knuckle and a second end pivotally coupled to a mechanical linkage, a second tie rod having a first end pivotally coupled to the second knuckle and a second end pivotally coupled to the mechanical linkage, and an electrical actuator coupled to the mechanical linkage. The mechanical linkage is arranged in front of the electrical actuator relative to a travel direction.
