Automotive Electronic Ball Screw

According to the "Research on Parking Force of Automotive Electronic Parking Brake System (EPB)", EPB drive components include electric motor, deceleration mechanism and parking brake.

According to the "Research on Parking Force of Automotive Electronic Parking Brake System (EPB)", EPB drive components include electric motor, deceleration mechanism and parking brake. When the driver presses the button of the electronic parking brake system, the electronic parking brake system control module receives the signal from the button, and the control module will apply current to the motor of the actuator to make it rotate.

The torque released by the motor reduces the speed of the motor and increases the torque through the deceleration and torque increase mechanism, and then converts the output torque of the electric brake unit into linear thrust through the output shaft thread pair or Ball Screw pair, thereby promoting the brake piston movement and converting the thrust into the pressure of the brake block pressed to the brake disc, thus achieving vehicle reduction or parking braking.
