摘　　要：双向自增力鼓式制动器因其效能因数高,在越野车和轻型卡车上作为中央驻车制动器应用较多。就双向自增力中央制动器在开发过程中的几项设计要点进行了详述,解析了自增力鼓式驻车制动器效能因数的计算方法,并通过理论计算和试验对比,验证了方法的准确性。同时,分析了摩擦系数的选择方法,对制动间隙的设计和控制进行了研究。Bi-directional-servo drum brakes has been used on off-road trucks and light trucks commonly as central parking brake because of its high efficiency factor. Several designing points of the development for bi- directional-servo parking brake have been detailed in this paper, it analyzing the calculation methods of efficient factor for bi-directional-servo parking brake and having been proved the correctness through comparing between theoretical calculations value and test value, analyzing the method of choosing value for friction coefficient and also researching how to designing and controlling brake clearance.
