主动转向系统汽车转向系统发展的标志是引入液压伺服机构和用轻便、廉价的齿轮齿杆式转向器代替轿车上的循环球式转向器。在紧凑和轻便的轿车上,液压伺服机构又受到最新的机电伺服转向器替代。真正的线控转向(steer by wire)系统由于受到汽车法规的限制至今还未被允许使用。转向系统的这些发展都是追求易于转向和转向力限制在适当的范围这 Active Steering System The hallmark of the automotive steering system is the introduction of a hydraulic servo and the replacement of a recirculating ball steering gear on a sedan with a lightweight, inexpensive gear-toothed steering gear. In the compact and lightweight sedan, the hydraulic servo is replaced by the latest electromechanical servo steering gear. The true steer by wire system has not yet been approved due to vehicle regulations. These developments in the steering system are the pursuit of ease of steering and steering forces limited to the proper range of this
