微型汽车转向系统毕业设计外文文献翻译 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 (Elect ric Hydraulic Power Steering， is called EHPS)， develops the electrically operated boost steering system (Elect ric 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 pilots 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 l
