Abstract
The present disclosure relates to a steering system comprising a rotatable steering wheel hub; a steering system support column including an off-axis section and an aligned section that are connected by a connection portion. The steering wheel hub is rotatably mounted on the aligned section, while the off-axis section is axially spaced from the steering wheel hub. The steering system comprises a torque feedback device including an electric machine having a rotor and a stator, the 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 aligned section of the steering system support column.
Claims19
A steering system for a vehicle, comprising:
- a steering wheel hub configured to be directly or indirectly connected with a steering wheel, the steering wheel hub being rotatable about an axis of rotation;
- a steering system support column comprising:
- an off-axis section having a first longitudinal axis that is off-set to the axis of rotation;
- and
- 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
- a torque feedback device comprising an electric machine having a rotor and a stator, the 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 aligned section of the steering system support column,
- wherein the rotor is an outer rotor and the stator is an inner stator,
- wherein the off-axis section and the aligned section are connected by a connection portion, the connection portion extends transversally to both the first longitudinal axis and the second longitudinal axis.
