1-20. (canceled)
An actuator assembly comprising:
- a first shaft;
- a single torsion bar providing only electromagnetic torque responsive to a torque input to said first shaft;
- a tooth assembly having an inner tooth and an outer tooth connected to a second shaft;
- and
- a magnet disposed between said inner tooth and said outer tooth, said magnet operative to interact with said tooth assembly to induce torque between said first shaft and said second shaft.
2 more elements
A steering system having an assembly for providing torque between a handwheel and a shaft comprising:
- a handwheel operative to receive a torque input from a user;
- an actuator assembly having a first shaft connected to said handwheel;
- a single torsion bar providing only electromagnetic torque responsive to said torque input, including a tooth assembly having an inner tooth and an outer tooth connected to a second shaft and a magnet disposed between said inner tooth and said outer tooth, said magnet operative to interact with said tooth assembly to induce torque between said first shaft and said second shaft.
