摘　　要：介绍了双回路气制动系统在内燃牵引车如何有效地应用。该系统通过使用液压元件和气压元件,保证当一个制动回路失灵后,第二个制动回路能正常工作。同时在两套管路中设置比例阀,分别调节前后制动器分泵压力,使每个车轮有合适的制动力,充分利用整车附着力,使得工程车辆既能达到最大的制动力,保证整车安全可靠性。气源通过气制动控制系统与制动泵相连接,能够实现牵引的挂车制动的远程集中控制。同时利用重型卡车成熟的气制动控制元件和叉车成熟的液压制动执行元件,满足了港口牵引车的制动安全性、结构的紧凑性,又能够实现牵引的挂车制动的远程集中控制,具有很好的拓展性。This article introduces the effective implication of two-circuit braking system in internal combustion tractor. This system uses hydraulic components and pneumatic components to make sure the second circuit braking system is in working order when the first fails. Meanwhile, proportional valves are installed in both circuits to adjust the pressure of front and rear brakes. Therefore, each wheel has appropriate brake force. By taking advantages of friction, the vehicle can achieve the maximum braking force which ensures safety and reliability. Air source is connected with the brake pump through air braking control system, thus to realize the remote centralized control of the braking of trailer. Moreover, it applies mature air brake components of heavy truck and mature hydraulic components of forklift truck. So that it satisfies braking safety and structural compactness, which has favorable expansibility.
