Abstract
An electric commercial vehicle power steering system includes an input shaft, an electric motor, and a planetary gear set, a drive coupling, and an output shaft. A first one of a sun gear, a planet carrier, and a ring gear of the planetary gear set is connected to and rotatable with a rotor of the electric motor, and a second one of the sun gear, the planet carrier, and the ring gear of the planetary gear set is connected to and rotatable with a first gear of the drive coupling. A second gear of the drive coupling is connected to and rotatable with the input shaft. A globoidal worm drive is arranged between the input shaft and the output shaft. The globoidal worm drive couples the input shaft to the output shaft such that the output shaft is rotatable with the input shaft via the globoidal worm drive.
