Manual Steering Gear

This steering system converts rotary motion to linear motion as follows; when the steering wheel is turned, rotary motion is transferred to the steering shaft, shaft joint and rack pinion. The pinion teeth mesh with teeth on the rack and the rotary motion is transferred to the rack and changed to linear motion. The linear force is then transmitted through the tie rods and to the steering knuckles which steer the front wheels.
