Recirculating Ball Electric Power Steering

RB-EPS is a special type of EPS whose rocker arm is connected to the steering knuckle of vehicle. 

The torque output by the RB-EPS motor is transmitted to the rocker arm shaft after three stages of deceleration, which respectively are worm & gear, ball screw pair and rack & pinion. The rocker arm shaft then drives the rocker arm to rotate and output torque.

The output torque range of RB-EPS is generally 300Nm~2000Nm. RB-EPS is generally used in mini-trucks and light trucks.
