Steering Angle Actuator

Steering angle actuator mainly consists of the sub motor angle sensor (1), the sub reduction gear (2), the steering gear (3), main reduction gear (4), the main motor angle sensor (5), the steering angle main motor (6), the steering torque sensor (7), and the steering angle sub motor (8).

STEERING GEAR 

Steering gear converts the pinion torque into rack axial force and changes the direction of the tires by rotating the knuckle arms.

STEERING TORQUE SENSOR 

Steering torque sensor detects the pinion torque and outputs the toque signal to the steering angle main control module by converting into voltage.

STEERING ANGLE MAIN MOTOR 

Steering angle main motor generates a steering torque by the traction current from the steering angle main control module.

MAIN REDUCTION GEAR 

Main reduction gear increases the steering torque provided from steering angle main motor with worm gears, and outputs to the pinion.

MAIN MOTOR ANGLE SENSOR 

Main motor angle sensor detects the angular velocity of the steering angle main motor and outputs to the steering angle main control module by converting into voltage.

STEERING ANGLE SUB MOTOR 

Steering angle sub motor generates an assist torque by the traction current from the steering angle sub control module.

SUB REDUCTION GEAR 

Sub reduction gear increases the steering assist torque provided from steering angle sub motor with worm gears, and outputs to the steering rack.

SUB MOTOR ANGLE SENSOR 

Sub motor angle sensor detects the angular velocity of the steering angle sub motor and outputs to the steering angle sub control module by converting into voltage.
