Independent suspension steering system

This invention relates to a steering system for an independent suspension, and more particularly, the invention relates to a so-called steer-by-wire steering system. A steering system is provided for a vehicle including a frame. Upper and lower control arms have first end portions that are pivotally supported on the frame at first spaced apart connections. The control arms also each include second end portions that are pivotally connected to an intermediate support member at second spaced apart connections. A steer knuckle is pivotally supported by the intermediate support member at third spaced apart connections that define a king pin axis. A drive motor is mounted on the intermediate support member and is coupled to the steering knuckle to rotate the steering knuckle about the king pin axis relative to the intermediate support member. A gear set may also be used in conjunction with the drive motor and steering knuckle. The intermediate support member is constrained against forward and aft movement, but is permitted to move upward and downward with the control arms.
