Abstract

A steering system includes a steering column for rotation between at least a center position and a range of second positions and defining a central axis. The steering system also includes an actuatorassembly in operative communication with the steering column to provide steering assistance, the actuator assembly comprising a pair of plates, each plate including a first helical track and a secondhelical track. The steering system further includes a spring element arranged with the actuator assembly to bias movement of one of the pair of plates along the central axis to influence the steeringcolumn to move to the center position.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Provisional Patent Application Serial No. 62 / 838,123, filed April 24, 2019, the entire disclosure of which is incorporated herein by reference. technical field [0003] The invention relates to a rotational centering device for a steering column, in particular a rotational centering device for a steering column of a vehicle. Background technique [0004] The steering system may include an assembly for directing a set of wheels into a central orientation relative to a central axis of the vehicle unless steering input is applied to a steering wheel in mechanical communication with the set of wheels. This component assists in returning the set of wheels to the center position when there is no steering input or following the steering input. This assembly may include an electric actuator to help return the steering wheel to the center position. However, the electric ...
