Abstract
A steering gear for a steer-by-wire steering system of a motor vehicle may include a coupling rod which is supported in a steering gear housing and on which a threaded spindle is formed, with the threaded spindle being surrounded by a spindle nut. The threaded spindle and the spindle nut may be part of a helical gearing, and the coupling rod is movable along a longitudinal axis by way of the helical gearing. The coupling rod is movably mounted in the steering gear housing along the longitudinal axis by way of a pressure piece having two bearing elements arranged on opposite sides of the coupling rod in a circumferential direction of the longitudinal axis.

A steering gear for a steer-by-wire steering system of a motor vehicle, the steering gear comprising:
- a pressure piece that includes two bearing elements;
- a coupling rod movably mounted in a steering gear housing along a longitudinal axis by way of the pressure piece, wherein the two bearing elements of the pressure piece are disposed on opposite sides of the coupling rod in a circumferential direction of the longitudinal axis;
- and
- wherein for receiving the pressure piece the steering gear housing includes:
- a dome that extends in a radial direction;
- and
- a recess that is aligned with the dome, the recess being disposed on an inner face that opposes the dome,
- wherein a first bearing element of the two bearing elements is disposed in the recess and a second bearing element of the two bearing elements is received in the dome.
A steering gear for a steer-by-wire steering system of a motor vehicle, the steering gear comprising:
- a pressure piece that includes two bearing elements;
- and
- a coupling rod movably mounted in a steering gear housing along a longitudinal axis by way of the pressure piece, wherein the two bearing elements of the pressure piece are disposed on opposite sides of the coupling rod in a circumferential direction of the longitudinal axis;
- and
- a threaded spindle of a helical gearing disposed on a first end region of the coupling rod, wherein the coupling rod is movably mounted in the steering gear housing by way of the pressure piece in a second end region that opposes the first end region along the longitudinal axis, and wherein a profile of the coupling rod in the second end region is non-circular, and wherein a diameter of the profile in the second end region is smaller than a diameter of the first end region.
