Abstract
A recirculating-ball steering system for transmitting a steering movement to a steering arm, includes: a housing having a steering piston arranged inside the housing, wherein the steering piston includes a ball screw drive and is displaceable along its longitudinal axis, and an electrical actuator for assisting the movement of the steering piston. Also described is a vehicle having the recirculating-ball steering system.

A recirculating-ball steering system for transmitting a steering movement to a steering arm, comprising:
- a housing having a steering piston arranged inside the housing, wherein the steering piston includes a ball screw drive and is displaceable along its longitudinal axis, and
- an electrical actuator for assisting the movement of the steering piston;
- wherein the steering piston includes the ball screw drive, which is a first ball screw drive, so as to provide a first attack point by which a rotational movement is converted into a translational movement, and
- wherein the electrical actuator includes a stator arranged around a steering worm screw of the first ball screw drive and fixedly connected to the housing, and a rotor fixedly connected to the steering worm screw, so as to provide a second attack point via which a torque is transmitted to the steering worm screw.
