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。
依據 RZS 盤式製動器的工作原理,建立瞭其機構運動簡圖;計算和比較瞭該機構在有無製動盤情況下的自由度;攷慮閘調機構伸長量的影響,研究瞭該製動器在閘片間隙等于設定值和閘片間隙補償後製動倍率的變化情況。研究結果錶明:RZS 盤式製動器的製動倍率符閤工程設計要求;閘調機構的伸長量與閘片磨損量存在線性變化關繫;在閘片的整箇服役週期內,製動倍率幾乎不變。
의거 RZS 반식제동기적공작원리,건립료기궤구운동간도;계산화비교료해궤구재유무제동반정황하적자유도;고필갑조궤구신장량적영향,연구료해제동기재갑편간극등우설정치화갑편간극보상후제동배솔적변화정황。연구결과표명:RZS 반식제동기적제동배솔부합공정설계요구;갑조궤구적신장량여갑편마손량존재선성변화관계;재갑편적정개복역주기내,제동배솔궤호불변。
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.
