Steering device for motor vehicle, steer-by-wire steering system and motor vehicle

Abstract

A steering device for a motor vehicle, in particular for use in a steer-by-wire steering system, comprises a steering handle rotatable about an axis of the steering device, and a restoring torque generating arrangement coupled to the steering handle and configured to generate a torque that at least partially counteracts rotation of the steering handle. The restoring torque generating arrangement comprises a motor having a hollow core coaxial to the axis of the steering device, and a gear coupled to the motor and configured to transmit a torque produced by the motor to the steering handle. The gear has a hollow central region coaxial to the axis of the steering device and a gear ratio within the range from 20:1 to 100:1.
