pinion gear

基本解释

Amending the Shape of Pinion and Reducing the Round-gear Error;
根据齿轮啮合原理，建立了轮齿的精确齿形。
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）。
Amending the Shape of Pinion and Reducing the Round-gear Error;
环形齿轮或驱动小齿轮上齿磨损。

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.
