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.
