In the example shown above of a Drag Link system, we see why it is designed as it is with angled steering arms. The system inside the steering arms will produce Ackermann effect which needs to be canceled. 1) The driver turns the steering wheel left. 2) The drag link moves to the left. 3) As the drag link moves to the left, the ends move forward as the Pitman arm and the idler arm rotate around fixed points. 4) The inner tie-rod ends move forward with the drag link. 5) The outer tie-rod ends (at the ends of the steering arms) are forced wider apart by the motion of the drag link and inner tie-rod ends creating additional toe-out. The angled steering arms produce reverse Ackermann which cancels the systems attempt to spread out the wheels, thus this system as a whole provides us with neutral steering.
