Abstract
The steering system for use in an automotive vehicle includes a pinion gear operatively connected to a steering wheel, an elongate rack member meshingly engaging the steering pinion gear and operative to move reciprocally in response to rotation of the steering wheel, a rack housing reciprocally supporting the rack member and a tie rod connected to the road wheel of the vehicle. The system further includes a lever means, such as an articulated link, pivotally mounted to the rack housing and directly drivingly engageable with the tie rod to effect reciprocal movement thereof in response to reciprocal movement of the rack member. In another embodiment, a spur gear is interposed between gear teeth disposed on the rack member and on the tie rod so that reciprocal movement of the rack member rotates the pinion gear resulting in simultaneous reciprocal movement of the tie rod.
