Operation
• The assist torque generated by the EPS motor is transmitted to the worm wheel via the worm shaft drives the steering column main shaft.
• The assist torque from the EPS motor is amplified by the reduction ratio (23.5:1) between the worm shaft and worm wheel, and is transmitted to the steering column main shaft.
