The invention discloses a large-torque electric power steering device and relates to the technical field of steering equipment. The output end of a motor drives a first-stage driven wheel to rotate, the first-stage driven wheel drives a first-stage speed reducing plate to rotate, the first-stage speed reducing plate drives a second-stage driving wheel to rotate, the second-stage driving wheel drives a second-stage driven wheel to rotate, and the second-stage driven wheel drives a second-stage speed reducing plate to rotate; the second-stage speed reduction plate drives the lead screw to rotate, so that the nut assembly drives the output shaft to reciprocate, large-torque output is achieved through two-stage speed reduction, the output end of the motor, the first-stage speed reduction plate, the second-stage speed reduction plate and the lead screw are coaxially arranged, accurate transmission of output power of the motor is achieved, the structure is compact, and the occupied space is small.
本发明公开了大扭矩电动助力转向装置,涉及转向设备技术领域,电机的输出端带动一级从动轮转动,一级从动轮带动一级减速板转动,一级减速板带动二级主动轮转动,二级主动轮带动二级从动轮转动,二级从动轮带动二级减速板转动,二级减速板带动丝杆转动,从而使螺母组件带动输出轴往复运动,通过两级减速实现大扭矩输出,电机输出端、一级减速板、二级减速板和丝杆同轴设置,实现电机的输出动力精准传动,结构紧凑,占用空间较小。
