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 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.
　隨著汽車電子技術的迅猛發(fā)展,人們對汽車轉向操縱性能的要求也日益提高。汽車轉向系統(tǒng)已從傳統(tǒng)機械轉向、液壓助力轉向(Hydraulic Power Steering ,簡稱HPS) 、電控液壓助力轉向( Elect ric Hydraulic PowerSteering , 簡稱EHPS) , 發(fā)展到電動助力轉向系統(tǒng)(Elect ric Power Steering ,簡稱EPS) ,最終還將過渡到線控轉向系統(tǒng)(Steer By Wire ,簡稱SBW)。
機械轉向系統(tǒng)是指以駕駛員的體力作為轉向能源,其中所有傳力件都是機械的,汽車的轉向運動是由駕駛員操縱方向盤,通過轉向器和一系列的桿件傳遞到轉向車輪而實現(xiàn)的。機械轉向系由轉向操縱機構、轉向器和轉向傳動機械3大部分組成。
