Some cars have variable-ratio steering, which uses a rack-and-pinion gear set that has a different tooth pitch (number of teeth per inch) in the center than it has on the outside.
有些车的转向系角传动比是可变的，这种转向器采用齿轮齿条式，它在中间而不是外部，有不同的齿密度（每寸齿数）。
In this paper, the meshing theory of rack and pinion steering gear with variable ratio is studied systematically.
