A commercial electric vehicle power steering system (100) includes an input shaft (110), an electric motor (120), a planetary gear set (130), a transmission coupling (140), and an output shaft (150). A first of the sun gear (132), the planet carrier (136) and the ring gear (138) of the planetary gear set (130) is connected to and rotatable with the rotor (122) of the electric motor (120), and a second of the sun gear (132), the planet carrier (136) and the ring gear (138) of the planetary gear set (130) is connected to and rotatable with the first gear (142) of the transmission coupling (140). A second gear (144) of the transmission coupling (140) is connected to and rotatable with the input shaft (110). The toroidal worm drive (160) is arranged between the input shaft (110) and the output shaft (150). The toroidal worm drive (160) couples the input shaft (110) to the output shaft (150) such that the output shaft (150) is rotatable with the input shaft (110) via the toroidal worm drive (160).

    商用电动车辆动力转向系统(100)包括输入轴(110)、电马达(120)、行星齿轮组(130)、传动耦联部(140)和输出轴(150)。行星齿轮组(130)的太阳齿轮(132)、行星架(136)和齿圈(138)中的第一者连接到电马达(120)的转子(122)并且能够与其一起旋转,并且行星齿轮组(130)的太阳齿轮(132)、行星架(136)和齿圈(138)中的第二者连接到传动耦联部(140)的第一齿轮(142)并且能够与其一起旋转。传动耦联部(140)的第二齿轮(144)连接到输入轴(110)并且能够与其一起旋转。环面蜗杆传动机构(160)布置在输入轴(110)与输出轴(150)之间。环面蜗杆传动机构(160)将输入轴(110)耦联到输出轴(150),使得输出轴(150)能够经由环面蜗杆传动机构(160)与输入轴(110)一起旋转。
