Which of the following is a part of the steering linkage? Correct Answer Pitman arm

Explanation:

Pitman arm is also called steering arm and it transmits the steering movement to the wheel.

  • The Pitman arm is a linkage attached to the sector shaft of the steering box and track rod it converts the angular motion of the sector shaft into the linear motion needed to steer the wheels.
  • The pitman arm is a linkage which joins the steering box through sector shaft at the bottom of steering wheel shaft and on the other side to the track rod which is attached at the other end to the idler arm.
  • When the steering wheel is turned left or right, a worm gear at the bottom of the steering shaft turns a set of teeth. That action moves a gear that activates the pitman arm, causing the steering linkage to move the wheels.

Function of pitman arm:

  1. precisely directs the movement of all the other steering links.
  2. limits wheel wobble on bumpy surfaces.
  3. assures full wheel turning radius.
  4. helps to reduce steering wheel vibration.
