Rack an

31、d pinion steering is one of the oldest types of steering systems and is still used today. Inside the rack body a flat rack gear moves in a linear direction, driven by a circular gear called a pinion. The steering wheel is connected to the pinion gear (shaft). A worm gear box style of steering system is constructed of two main parts much like the rack and pinion style system. The main part is called a worm gear; the other is a selector shaft gear. The worm gear is connected to t
