VARIATIONS
The tie rods are either directly or indirectly connected to the
steering gear box:
- Recirculating ball type steering requires additional
steering linkages to be connected between the tie rods and steering gear box.
These additional components are Pitman arm,
center link,
idler arm, and frame bracket.
These linkages covert rotary output motion of the steering gear box to sideways
motion that the tie rods utilize.
- Rack-and pinion type steering permits direct connection
of the tie rods to the rack since the rack already moves in a sideways motion.
No extra linkage components are needed.
