靠圓盤間的摩擦力實現製動的製動器，主要有全盤式和點盤式兩種類型。
①全盤式製動器：由定圓盤和動圓盤組成。定圓盤通過導向平鍵或花鍵聯接(見鍵聯接、花鍵聯接)於固定殼體內，而動圓盤用導向平鍵或花鍵裝在製動軸上，並隨軸一起旋轉。當受到軸向力時,動、dingyuanpanxianghuyajinerzhidong。zhezhongzhidongqijiegoujincou，mocamianjida，zhidonglijuda，dansanretiaojiancha。weizengdazhidonglijuhuojianxiaojingxiangchicun，kezengduopanshuhezaiyuanpanbiaomianfugaiyicengshimiandengmocacailiao。
