Abstract
A handwheel actuator for a steering system includes a housing, a steering shaft supported by the housing and configured to be coupled to a handwheel for receiving driver input from a driver and transmitting feedback to the driver, a first spring for biasing the steering shaft in a first rotational direction, the first spring coupled to the steering shaft by a first static spring seat, a second spring for biasing the steering shaft in a second rotational direction opposite the first rotation direction, the second spring coupled to the steering shaft by a second static spring seat, a controlled spring seat coupled to the first spring and the second spring and rotatable to change a pre-load of at least one of the first or second springs. Rotation of the controlled spring seat changes a torsional load applied to the steering shaft via at least one of the first spring or the second spring.
