Brake system for steering feedback

Abstract:

A brake system for providing tactile feedback in a vehicle steering system. The brake system includes an input shaft, and a rotor responsive to the shaft to rotate in response to input steering wheel inputs. A friction element imparts a base load to the rotor, and an electromagnetic coil imparts a variable load to the rotor. A housing of the brake system includes a fixed component and an intermediate component threaded together to set the base load. An adjustable component of the housing is threaded to the intermediate component to calibrate the variable load. The friction element is disposed between, and engages, both the rotor and the intermediate housing to impart the feedback loads.
