An improved steering apparatus is utilized to turn a steerable wheel of the vehicle. The apparatus includes an axially movable push rod or force transmitting member which is connected with the steerable wheel of a vehicle. A screw thread is formed on the push rod and cooperates with a nut which is rotated by a bevel gear connected with an input member. In order to effect a change in the steering ratio, a cam track is formed in the push rod. A cam follower or pin cooperates with the track to effect rotation of the push rod relative to the nut as the push rod is moved axially due to the rotation of the input member and nut. |
