摘　　要：电力液压块式制动器在使用中会出现推动器推杆推不起来,制动器不能正常松闸的现象。本文以常闭式电力液压块式制动器为基础,从设计方法和结构形式等方面分析了制动器不松闸的原因,并提出了改进措施。It is found in the practice of electro-hydraulic shoe brake, that hydraulic thruster sometimes fails to push out its lifting rod to release the brake. On the basis of a normally applied brake, this paper analyses reason for that in terms of design method and construction of the brake. Measures of improvement are also presented in the paper.
