ABSTRACT:
A steering gear for turning steerable wheels of a vehicle comprises a member movable in opposite directions. The member has first and second portions. The first portion comprises a rack having gear teeth extending transverse to the direction of movement of the member. A manually rotatable pinion engages the rack for applying a first force to the rack. An electric motor applies a second force to the second portion of the member. The electric motor encircles the member and rotates a ball nut. The ball nut cooperates with a screw portion of the member to effect linear movement of the member in response to actuation of the motor.
