摘 要: In response to demands in recent years for steering systems enabling improved fuel efficiency and featuring compatibility with active safety technology, we have developed a high-powered Rack-Direct Electric Power Steering System (RD-EPS) with integrated Variable Gear Ratio Steering System (E-VGR) for full-sized passenger vehicles. RD-EPS consists of a ball screw type reduction gear, a rack-coaxial Brushless motor and an ECU with separated voltage booster, and in development of this new steering, we achieved higher-power performance of each of these parts. The E-VGR unit has been integrated on the EPS pinion gear upper area to achieve a compact, highly efficient structure.

为满足近年来对提升燃油效率并兼容主动安全技术的转向系统的需求,我们针对全尺寸乘用车开发了高功率齿条直驱电动助力转向系统(RD-EPS),并集成可变齿轮比转向系统(E-VGR)。RD-EPS由滚珠丝杠减速齿轮、齿条同轴无刷电机以及带独立电压升压器的ECU组成。在新系统的研发过程中,我们实现了各部件更高功率的性能表现。E-VGR单元被集成在EPS小齿轮的上部区域,以实现紧凑且高效的设计结构。
