针对目前国内轮胎式装载机气顶油钳盘式制动和全液压湿式制动系统做了具体的介绍,分析了单管路和双管路气顶油钳盘式制动系统的组成、工作过程和特点;同时,对气顶油钳盘式制动系统和全液压湿式制动系统的特点进行了比较。与气顶油钳盘式制动系统相比,全液压湿式制动系统具有以下优点:系统可直接与液压系统合用一泵,发动机上不用装空压机,省去了一套气路,具有一定的节能作用;由于该系统选用湿式制动器,制动摩擦片在封闭的冷却油内,抗污染能力强,使用寿命长,使整车制动更为安全可靠;由于液压油的可压缩性比空气低得多,因此全液压湿式制动系统的响应时间比气顶油钳盘式制动系统短,制动性能更加安全可靠。
Aiming at the present situation of disc brake and full hydraulic wet brake system of gas wheel oil-filled caliper in domestic tire loaders, the composition and work of disc brake system of gas pipe and double-pipe gas-top clamp are analyzed Process and characteristics; at the same time, compared the characteristics of gas-topped oil-disc type disc brake system and full hydraulic wet brake system. Compared with gas-topped caliper disc brake system, the full hydraulic wet brake system has the following advantages: the system can be directly combined with a hydraulic pump system, the engine without air compressor, eliminating the need for a set of gas, with A certain amount of energy-saving effect; as the system uses wet brakes, brake friction plates in the closed cooling oil, anti-pollution ability, long life, making the vehicle more secure and reliable braking; hydraulic compressibility than The air is much lower, so the full hydraulic wet brake system response time is shorter than the gas cap type caliper disc brake system, brake performance more safe and reliable.
