Along with automobile electronic technology swift and violent development, the people also day by day enhance to the motor turning handling quality request. The motor turning system changed, the hydraulic pressure boost from the traditional machinery changes (Hydraulic Power Steering, is called HPS), the electrically controlled hydraulic pressure boost changes (Electric Hydraulic Power Steering, is called EHPS), develops the electrically operated boost steering system (Electric Power Steering, is called EPS), finally also will transit to the line controls the steering system (Steer By Wire, will be called SBW).

The machinery steering system is refers by pilot's physical strength achievement changes the energy, in which all power transmission all is mechanical, the automobile changes the movement is operates the steering wheel by the pilot, transmits through the diverter and a series of members changes the wheel to realize. The mechanical steering system by changes the control mechanism, the diverter and major part changes the gearing 3 to be composed.

Usually may divide into according to the mechanical diverter form: The gear rack type, follows round the world -like, the worm bearing adjuster hoop type, the worm bearing adjuster refers sells the type. Is the gear rack type and follows using the broadest two kinds round the world -like (uses in needing time big steering force).In follows round the world -like in the diverter, the input changes the circle and the output steering arm pivot angle is proportional; In the gear rack type diverter, the input changes the turn and the output rack displacement is proportional. Follows round the world -like the diverter because is the rolling friction form, thus the transmission efficiency is very high, the ease of operation also the service life are long, moreover bearing capacity, therefore widely applies on the truck. The gear rack type diverter with follows round the world -like compares, the most major characteristic is the rigidity is big, the structure compact weight is light, also the cost is low. Because……

随着汽车电子技术的迅猛发展,人们对汽车转向操纵性能的要求也日益提高。汽车转向系统已从传统机械转向、液压助力转向(Hydraulic Power Steering,简称HPS) 、电控液压助力转向( Electric Hydraulic Power Steering, 简称EHPS) , 发展到电动助力转向系统(Electric Power Steering,简称EPS) ,最终还将过渡到线控转向系统(Steer By Wire,简称SBW)。

机械转向系统是指以驾驶员的体力作为转向能源,其中所有传力件都是机械的,汽车的转向运动是由驾驶员操纵方向盘,通过转向器和一系列的杆件传递到转向车轮而实现的。机械转向系由转向操纵机构、转向器和转向传动机械3大部分组成。

通常根据机械式转向器形式可以分为：齿轮齿条式、循环球式、蜗杆滚轮式、蜗杆指销式。应用最广的两种是齿轮齿条式和循环球式(用于需要较大的转向力时)。在循环球式转向器中,输入转向圈与输出的转向摇臂摆角是成正比的；在齿轮齿条式转向器中,输入转向圈数与输出的齿条位移是成正比的。循环球式转向器由于是滚动摩擦形式，因而正传动效率很高,操作方便且使用寿命长,而且承载能力强,故广泛应用于载货汽车上。齿轮齿条式转向器与循环球式相比，最大特点是刚性大,结构紧凑重量轻,且成本低。由于……
