Pitman arm
The pitman arm is a component of the steering in vehicles. It transfers the steering movement from the steering gear to a steering lever (via a steering rod) or the tie rods . In the case of individually suspended wheels, the tie rod is often divided into three parts, the middle and an outer part of the tie rod are connected on one side via the pitman arm and on the other via an additional power steering lever.
The rack and pinion steering used in modern cars do not require a pitman arm. The tie rods are attached directly to the rack, either together in the middle or outside on the left and right.
