隨著車輛技術的進步及道路條件的改善，汽車的行駛速度越來越高，這就對汽車製動性能提出越來越高的要求，因而製動器本身的設計及在整車上的匹配問題就是保證製動性能一個十分重要的問題。製動器在整車上製動力的配置涉及兩個方麵的問題
，一是前、後hou軸zhou製zhi動dong器qi製zhi動dong力li分fen配pei比bi的de選xuan擇ze
，一yi般ban設she計ji時shi選xuan擇ze合he理li的de分fen配pei比bi，使shi理li想xiang製zhi動dong力li分fen配pei線xian與yu實shi際ji製zhi動dong力li分fen配pei線xian攝she接jie近jin，這zhe涉she及ji到dao整zheng車che製zhi動dong效xiao率lv的de高gao低di及ji製zhi動dong穩wen定ding性xing的de好hao壞huai，這zhe也ye往wang往wang是shi大da家jia注zhu意yi的de重zhong點dian，這zhe方fang麵mian已yi有you諸zhu多duo文wen章zhang
