Mechanism for limiting angular movement in steering systems for motor

Abstract

An angular movement limiting mechanism is incorporated in a steering system for a motor vehicle includes a steering handle, a pair of steerable wheels, a pair of knuckles on which the steerable wheels are rotatably supported, a pair of knuckle supporting members on which the knuckles are angularly movably supported, and a pair of tie rods operatively coupled between the steering handle and the knuckles for transmitting angular movement of the steering handle to the knuckles. The angular movement limiting mechanism comprises a pair of stoppers mounted on the knuckle supporting members, respectively, and engageable with the knuckles, respectively, for limiting angular movement of the knuckles. The stoppers and the knuckles are relatively positioned such that when the steering handle is turned through a maximum angle, there is a clearance kept between the knuckle coupled to the tie rod being pushed and the stopper associated therewith.
