Abstract

A steering booster configuration for motor vehicles has a shaft rotatable about a longitudinal axis. An electric disk armature motor with a coaxially disposed planetary gearing is connected to the shaft for stepping up the motor power. The motor has a rotor disk which is supported on the shaft, and is offset parallel with respect to the axis. A hollow toothed gear is fastened to the rotor and wobbles about the axis.
