用热容量作为制动容量的计算准则由来已久,这种方法对制动行程有严格要求的设备和车辆缺乏准确性.由于目前摩擦材料抗热衰退性能和容许压强的大幅度提高、已有可能完全从车辆的运行性能出发来准确计算制动容量了.本文企图按ISO标准,从对装载机运行性能的要求,结合对国内几个主要装载机制动性能的试验分析,提出了按最低限容量法设计制动钳,可以提高设计的经济性. The calculation of the heat capacity as a braking capacity has been a long term and this method lacks accuracy for equipment and vehicles that have severe demands on the brake travel.Due to the current substantial improvement in the resistance to thermal degradation and allowable pressure of friction materials, Completely from the vehicle performance to accurately calculate the braking capacity.This paper attempts to ISO standards, from the requirements of the loader performance, combined with several major domestic loader brake performance test analysis, proposed by the minimum capacity Design caliper brake can improve the design of the economy.
