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.

Actuator for a vehicle steering device

A gear for vehicle steering systems, in which, by pivoting a shaft of a pinion in the radial direction by means of a spring element, play-free transmission of the rotary motion from the shaft to a power takeoff shaft is assured.

Play-free steering gear

A final control element for superimposed steering engagement of a vehicle steering system with a superposition gear having two input shafts and one output shaft, in order to attain a radial freedom from play, the superposition gear is provided with a two-stage, modified planetary gear, having a planet carrier, at least one stepped planet comprising two axially aligned planet wheels connected to one another fixed against relative rotation, and two sun wheels or ray wheels; the first input shaft is connected to one sun or ray wheel, and the output shaft is connected to the other sun or ray wheel, fixed against relative rotation, while the planet carrier is drivable via the second input shaft, and the at least one stepped planet and the sun wheels are biasing toward provided for suppressing a tooth flank play that occurs between.
