Airplane wheel brake system capable of selecting slipping braking mode according to braking pressure

Provided is an airplane wheel brake system capable of selecting a slipping braking mode according to braking pressure. The airplane wheel brake system comprises a hydraulic brake valve, an electro-hydraulic servo valve, a control box, a magnetic valve, a pressure sensor and an airplane wheel speed sensor. The control box, the electro-hydraulic servo valve and the airplane wheel speed sensor form a brake slipping prevention control part. The magnetic valve, the pressure sensor and the control box are used for achieving braking selection for a brake airplane wheel. The pressure sensor is installed on a hydraulic pipeline at a brake opening of the electro-hydraulic servo valve. The hydraulic pipeline delivered from the brake system to an airplane wheel brake device is divided into two paths, and the two paths communicate with a small brake device oil inlet and a large brake device oil inlet correspondingly. By controlling the two paths of the hydraulic pipeline, only a small brake device operates when an airplan
