Steering wheel unit for generating a feedback force on a steering wheel for an electromechanical steering system

摘要

The invention relates to a steering wheel unit (1) for an electromechanical steering system of a motor vehicle (24). The steering wheel unit (1) has a force generating means for loading the steering wheel (4) with a mechanical feedback force via the current steering and / or driving condition to the driver and a compensator (10) for generating an additional feedback force depending on the current transverse force which the motor vehicle (24) acts on. The force generating means has an internal gear (12) which rotates in the same direction as the steering wheel (4), and first and second radial springs (16a, 16b), the first and second radial springs (16a, 16b) each having the internal gear (12) and a housing (2) of the steering wheel unit (1) are connected and apply force to the steering wheel (4) via the internal gear (12) in such a way that with increasing adjustment of the steering wheel (4) which deviates from driving straight ahead, the feedback force increases can be generated on the steering wheel (4) for reporting back a steering angle-related steering state to the driver. The equalizer is connected to the steering shaft (3) via an equalizing pinion (22) and is set up to exert the additional feedback force on the steering wheel (4) depending on the lateral force.
