The invention relates to a cylindrical gear and planet wheel combined type electric power-assisted recirculating ball steering gear. The cylindrical gear and planet wheel combined type electric power-assisted recirculating ball steering gear is characterized in that a power unit assembly and a primary speed reducer assembly are fixed together with a mechanical recirculating ball steering gear assembly; the cylindrical gear reducer assembly is assembled between the gearbox side cover assembly and the mechanical recirculating ball steering gear; the gearbox side cover assembly and the mechanical recirculating ball steering gear assembly are fixed together; the inner gear ring and the mechanical recirculating ball steering gear assembly are fixed together; the steering arm shaft assembly with the planet wheel speed reducing mechanism is assembled on the mechanical recirculating ball steering gear assembly through an arm shaft input end bearing and an arm shaft output end bearing and then is axially fixed through a steering arm shaft fixing nut. A traditional mechanical recirculating ball steering gear is effectively combined with a gear and a planet wheel, electric power steering of a commercial vehicle can be achieved, and the electric power steering device has the advantages of being efficient, capable of saving energy and easy to arrange the whole vehicle.

    本发明涉及一种圆柱齿轮与行星轮组合式电动助力循环球转向器,其特征在于:动力单元总成和初级减速器总成与机械式循环球转向器总成固定在一起;圆柱齿轮减速器总成装配在齿轮箱侧盖总成及机械式循环球转向器之间;齿轮箱侧盖总成与机械式循环球转向器总成固定在一起;内齿圈与机械式循环球转向器总成固定在一起;带有行星轮减速机构的转向臂轴总成通过臂轴输入端轴承及臂轴输出端轴承装配在机械式循环球转向器总成上,然后通过转向臂轴固定螺母进行轴向固定。其有效的将传统的机械式循环球转向器与齿轮及行星轮结合在一起,可实现商用车的电动助力转向,具有高效、节能、易整车布置的优点。
