Abstract
A feedback actuator for a steering mechanism for motor vehicles may include a steering adjuster that acts on the steered wheels and is controlled electronically based on steering commands of a drive of the motor vehicle. The feedback actuator may transmit feedback from a road to a steering wheel via a steering shaft. Further, the feedback actuator may have a preloaded belt drive and an electric motor configured as torque-generating means. The feedback actuator may generate a torque to simulate the feedback of the road. The torque may be formed by a sum of a torque from the preloaded belt drive applied to the steering shaft and a torque from the electric motor applied to the steering shaft.
Claims18
A feedback actuator for a steering mechanism for a motor vehicle, the feedback actuator comprising:
- a steering adjuster that acts on steered wheels and is controlled electronically based on steering commands of a driver of the motor vehicle;
- a steering shaft via which feedback from a road is transmitted to a steering wheel;
- and
- a preloaded belt drive and an electric motor configured as torque-generating means,
- wherein the preloaded belt drive comprises a spring-loaded cable pull.
A steer-by-wire steering mechanism for a motor vehicle comprising:
- a steering adjuster that acts on steered wheels and is controlled electronically based on steering commands of a driver of the motor vehicle;
- and
- a feedback actuator that transmits feedback from a road to a steering wheel via a steering shaft, wherein the feedback actuator includes a preloaded belt drive and an electric motor configured as torque-generating means,
