The invention discloses a power-assisted steering device for a new energy automobile, and relates to the technical field of steering systems. According to the power-assisted steering device for the new energy automobile, a third gear correspondingly meshes with a first gear and a second gear on the two sides of the third gear, a first electromagnetic damper is installed at the top of an installation plate 1, a central processing unit gives resistance to an output shaft of a first speed reducer after sending a signal, a second electromagnetic damper is installed at the top of the installation plate 1, and the central processing unit gives resistance to an output shaft of a second speed reducer after sending a signal. According to the power-assisted steering device for the new energy automobile, the mode of meshing of the two sets of gears is adopted, a meshing tooth direction gap of one set of gears can be eliminated, the hysteresis quality of assisting power during direction changing is eliminated, so that the power-assisted system is more reliable, safer and more stable, the adopted gears are cylindrical gears, processing is easy, and cost is low.
本发明公开了一种新能源汽车用转向助力装置,涉及转向系统技术领域。一种新能源汽车用转向助力装置,包括所述第三齿轮分别与第一齿轮和第二齿轮在第三齿轮两侧啮合,所述第一电磁阻尼器安装于安装板1的顶部,中央处理器给出信号后,给与第一减速器输出轴阻力,所述第二电磁阻尼器安装于安装板1的顶部,中央处理器给出信号后,给与第二减速器输出轴阻力。本发明转向助力系统为两组齿轮啮合的方式,可以消除一组齿轮啮合的齿向间隙,消除变向时助力的滞后性,让助力系统更加可靠、安全和稳定,而且采用的齿轮为圆柱齿轮,加工容易,成本低。
