The system can automatically measure Riss hardness of steering gear rack, and then transform it into corresponding Rockwell, Brinell and Vickers hardness.

该系统可自动测试转向器齿条的里氏硬度，可转换成相应的洛氏、布氏、维氏值，并按生产要求自动进行分选。

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）。

Another distinguishing feature is the speed-sensitive power steering with rack-and-pinion steering gear: the power assistance is implemented electrohydraulically rather than just hydraulically.
