More Information
Summary:A steering column assembly includes a column jacket extending along a longitudinal axis and a steering shaft rotatably supported by the column jacket. A power assist module includes a housing coupled to the column jacket and a motor. The motor applies a torque to the steering shaft. An isolator connection interconnects the housing and the column jacket to permit rotational flexure of the power assist module relative to the column jacket, i.e., the power assist module may rotate relative to the column jacket, thereby preventing undesirable rotation of a lever mounted to the column jacket in response to the motor applying the torque to the steering shaft.
