Abstract
The present disclosure relates to a steering system comprising a steering wheel mechanically attached to a steering wheel hub by fixing elements; a steering system support column, wherein the steering wheel hub is rotatably mounted on the steering system support column, so that the steering wheel and the steering wheel hub are rotatable); a torque feedback device including an electric machine having an outer rotor and an inner stator with stator windings, the outer rotor being attached to the steering wheel hub so as to be rotatable with the steering wheel hub, and the stator being non-rotatably fixed to the steering system support column; wherein, with respect to the axis of rotation, the fixing elements are arranged at different radial positions than the stator windings.
Claims17
A steering system for a vehicle, comprising:
- a steering wheel and a steering wheel hub, wherein the steering wheel is mechanically attached to the steering wheel hub by fasteners;
- a steering system support column formed integrally, wherein the steering wheel hub is rotatably mounted on the steering system support column, so that the steering wheel and the steering wheel hub are rotatable about an axis of rotation;
- and
- a torque feedback device including an electric machine having an outer rotor and an inner stator with stator windings, the outer rotor being attached to the steering wheel hub so as to be rotatable with the steering wheel hub about the axis of rotation, and the stator being non-rotatably fixed to the steering system support column,
- wherein, with respect to the axis of rotation, the fasteners are arranged at different radial positions than the stator windings,
- wherein the steering system support column comprises an off-axis section having a first longitudinal axis that is off-set to the axis of rotation and including an aligned section having a second longitudinal axis that corresponds to the axis of rotation, wherein the steering wheel hub is rotatably mounted on the aligned section, while the off-axis section is axially spaced from the steering wheel hub, and
- wherein the stator is non-rotatably fixed to the aligned section of the steering system support column.
