Abstract
The vehicle steering system includes front vehicle motive members, rear vehicle motive members, a steering input device, a front steering subsystem, a rear steering subsystem and a rear steering control mechanism. The front steering subsystem is operably coupled to the steering input device and coupled to the front motive members to steer the front motive members. The rear steering subsystem is coupled to the rear motive members to steer the rear motive members. The rear steering control mechanism includes a movable input member coupled to the steering input device so as to move in response to input from the device and a movable output member coupled to the rear steering subsystem. The rear steering subsystem adjusts steering of the rear motive members in response to movement of the output member. The control mechanism operates in a rear steering state in which force is transmitted from the input member to the output member to move the output member and a dwell state in which the output member does not move in response to movement of the input member.
