Abstract

A steering system with an electric motor includes a hollow shaft through which a rod is passed, the rod being drivable in the longitudinal direction by the electric motor through a worm gear. An intermediate transmission is provided, which reduces the rpm of the electric motor. The hollow shaft is connected torque-proof with a driving outer contour, which transfers torque to the intermediate transmission. The intermediate transmission has a first gear wheel, an axle of which is supported so as to be stationary, and the outer contour of which transfers torque. The worm of the worm gear is formed on the rod. A nut of the worm gear is drivable by the intermediate transmission. For greater economy of construction of the steering system, a second gear wheel with a torque-transferring outer contour, connected over an intermediate shaft torque-proof with the first gear wheel. The intermediate transmission transfers torque to an outer contour, which is connected torque-proof with the nut.
