Abstract
An actuator for superimposed steering engagement in a vehicle steering system having first and second input shafts, an output shaft coaxial with the first input shaft, and a superposition gear disposed between the shafts. The superposition gear has a two-stage, modified planetary gear that has respective sun wheels fixed on the first input shaft and the output shaft, respectively, a satellite carrier that can be driven by the second input shaft, and at least one stepped planet with two respective planet wheels that mesh with the sun wheels. The planet wheels are, spaced apart axially from one another, one on each end portion of a smaller-diameter shaft portion with which they are integral.
