盤式製動器工作原理

    盤式製動器工作原理

    製動時
，油液被壓入內、外兩輪缸中
、其qi活huo塞sai在zai液ye壓ya作zuo用yong下xia將jiang兩liang製zhi動dong塊kuai壓ya緊jin製zhi動dong盤pan
，產chan生sheng摩mo擦ca力li矩ju而er製zhi動dong。此ci時shi，輪lun缸gang槽cao中zhong的de矩ju形xing橡xiang膠jiao密mi封feng圈quan的de刃ren邊bian在zai活huo塞sai摩mo擦ca力li的de作zuo用yong下xia產chan生sheng微wei量liang的de彈dan性xing變bian形xing。放fang鬆song製zhi動dong時shi
，活huo塞sai和he製zhi動dong塊kuai依yi靠kao密mi封feng圈quan的de彈dan力li和he彈dan簧huang的de彈dan力li回hui位wei。由you於yu矩ju形xing密mi封feng圈quan刃ren邊bian變bian形xing量liang很hen微wei小xiao，在zai不bu製zhi動dong時shi，摩mo擦ca片pian與yu盤pan之zhi間jian的de間jian隙xi每mei邊bian隻zhi有you0.1mm左右，它足以保證製動的解除。又因製動盤受熱膨脹時
，其厚度隻有微量的變化，故不會發生“托滯”現xian象xiang。矩ju形xing橡xiang膠jiao密mi封feng圈quan除chu起qi密mi封feng作zuo用yong外wai，同tong時shi還hai起qi到dao活huo塞sai回hui位wei和he自zi動dong調tiao整zheng間jian隙xi的de作zuo用yong。如ru果guo製zhi動dong塊kuai的de摩mo擦ca片pian與yu盤pan的de間jian隙xi磨mo損sun加jia大da
，製zhi動dong時shi密mi封feng圈quan變bian形xing達da到dao極ji限xian後hou
，活huo塞sai仍reng可ke繼ji續xu移yi動dong
，直zhi到dao摩mo擦ca片pian壓ya緊jin製zhi動dong盤pan為wei止zhi。解jie除chu製zhi動dong後hou，矩ju形xing橡xiang膠jiao密mi封feng圈quan將jiang活huo塞sai推tui回hui的de距ju離li同tong磨mo損sun之zhi前qian相xiang同tong，仍reng保bao持chi標biao準zhun值zhi。
