摘　　要：依据RZS盘式制动器的工作原理,建立了其机构运动简图;计算和比较了该机构在有无制动盘情况下的自由度;考虑闸调机构伸长量的影响,研究了该制动器在闸片间隙等于设定值和闸片间隙补偿后制动倍率的变化情况。研究结果表明:RZS盘式制动器的制动倍率符合工程设计要求;闸调机构的伸长量与闸片磨损量存在线性变化关系;在闸片的整个服役周期内,制动倍率几乎不变。Firstly,according to the working principles of the braking unit RZS,the kinematic dia-gram was built up.Then,the DOF of RZS with and without the brake disc was analyzed and com-pared.The braking rate and its change rules were calculated and analyzed respectively under two con-ditions：the pad clearance was equal to the setting value and another the pad clearance was reset after braking operation.It is found that：the braking rate of RZS meets the design requirements and there is a linear relationship between the increment of the self-adjustment mechanism and the amount of the pad’s wear.During the entire service life of the pad,the braking rate of RZS barely changes.
