Force transmitting system for steering wheel of motor vehicle, has passive force transmitting device occupying clutched state in which it applies torque to steering wheel, and declutched state in which it does not apply torque to wheel

摘要

The system has an active force transmitting device (16) applying a force transmitting torque to a steering wheel (12). A passive force transmitting device (18) applies a restoring torque to the steering wheel towards its reference position. The passive force transmitting device occupies a clutched state in which the device (18) applies the restoring torque to the steering wheel, and a declutched state in which the device (18) does not apply the restoring torque to the steering wheel.
