  • Publication number: 20170057797
    Abstract: A forklift truck brake system includes a drive, a gear box, a traction motor connected to the gear box, wheels and tires rotatably mounted on opposed ends of the drive axle, the gear box being connected to the drive axle, and the traction motor causes rotation through the gear box to rotate the wheels and tires. The system also includes a brake disc installed on an output shaft of the traction motor, and a brake is configured to clamp the brake disc and stop it from rotating. The brake is used to make the brake disc on the output shaft of the traction motor stop rotating, so that the traction motor stops rotating, and the brake force of the motor is amplified by the gear box and drive axle, to achieve quick braking and reduce the braking distance.
