Steering gear for a vehicle
View Patent ↗A steering gear for a vehicle includes a steering pinion and a master rack. A toothing of the master rack includes a constant helix angle and a toothing of the steering pinion includes a changing helix angle.
1. A steering gear assembly for a vehicle, comprising:
a toothed steering rack; and
a steering pinion configured to mesh with the toothed steering rack,
wherein a transmission ratio of the toothed steering rack and the steering pinion is configured to change with a rotation of a steering wheel of the vehicle,
wherein a rack toothing of the toothed steering rack has a constant helix angle, and
wherein a pinion toothing of the steering pinion has a helix angle that changes over a circumference of the steering pinion.
2. The steering gear assembly as claimed in claim 1 , wherein:
the pinion toothing includes at least two helix angle sections having different helix angles; and
the helix angle of each of the at least two helix angle sections is constant.
3. The steering gear assembly as claimed in claim 2 , wherein the helix angles of the at least two helix angle sections differ by at least 10°.
4. The steering gear assembly as claimed in claim 2 , wherein the helix angles of the at least two helix angle sections differ by at most 45°.
5. The steering gear assembly as claimed in claim 1 , wherein:
the steering pinion defines an axis of rotation; and
the steering pinion is mounted in a gear housing exclusively about the axis of rotation.
