只有施(shi)加外力(li)才能(neng)(neng)解(jie)除制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)狀(zhuang)態。起重機(ji)械中的提(ti)升機(ji)構(gou)常采(cai)用(yong)常閉式制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)答(da)，而(er)各種車輛的主(zhu)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)則采(cai)用(yong)常開(kai)式。常見(jian)的制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)多(duo)采(cai)用(yong)摩(mo)擦制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)，按其結構(gou)特(te)征可分(fen)(fen)(fen)為(wei)塊式、帶式和盤(pan)式。它們都是利(li)用(yong)摩(mo)擦元件之(zhi)間(jian)產生摩(mo)擦阻(zu)力(li)矩(ju)來消耗機(ji)械運動(dong)(dong)(dong)(dong)部(bu)件的動(dong)(dong)(dong)(dong)能(neng)(neng)，以達(da)到制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)的目的。主(zhu)要由(you)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)架、摩(mo)擦元件和驅動(dong)(dong)(dong)(dong)裝置(zhi)三(san)部(bu)分(fen)(fen)(fen)組(zu)成(cheng)。制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)架是制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)其他(ta)部(bu)分(fen)(fen)(fen)安裝和支(zhi)承的基礎。

摩擦(ca)元件與制(zhi)(zhi)動輪為面接(jie)觸，以(yi)產生制(zhi)(zhi)動摩擦(ca)力(li)矩。驅(qu)動裝置(zhi)則(ze)將作用于(yu)制(zhi)(zhi)動器的驅(qu)動力(li)放大(da)并(bing)傳遞(di)給(gei)章擦(ca)元件以(yi)實現(xian)制(zhi)(zhi)動（緊閘）或使康擦(ca)元件與制(zhi)(zhi)動輪脫離接(jie)觸而松閘。n液壓制(zhi)(zhi)動(dong)(dong)器是由濕式、多片(pian)行車(che)制(zhi)(zhi)動(dong)(dong)器依靠(kao)液壓驅動(dong)(dong)，制(zhi)(zhi)動(dong)(dong)平順，使用(yong)成本低(di)。在每個串(chuan)聯車(che)輪上(shang)設置了液壓制(zhi)(zhi)動(dong)(dong)器，因此，機具有(you)大的制(zhi)(zhi)動(dong)(dong)面積，并傳遞可靠(kao)的剎車(che)動(dong)(dong)力(li)。

延長(chang)制(zhi)動壽命。使(shi)用方便的制(zhi)動磨損(sun)指示/補償系統維(wei)(wei)持著(zhu)不(bu)變(bian)的制動(dong)(dong)性(xing)能，無(wu)需(xu)拆卸即可指示(shi)制動(dong)(dong)磨損情況。該系統減(jian)少了(le)維(wei)(wei)護，延長(chang)了(le)液壓(ya)制動(dong)(dong)器服務壽命。通(tong)過卡特(te)信控(kong)器駕駛(shi)員可以方(fang)便地設置各種(zhong)換擋參數(shu)，以滿足特(te)殊的使用要求(qiu)。這一特(te)性(xing)可在(zai)佳點自動(dong)(dong)換擋，從而使駕駛(shi)員能夠把注意(yi)力集中(zhong)到(dao)作業上，提高了(le)安(an)全(quan)性(xing)、生產(chan)率和操作方(fang)便性(xing)。

n塊(kuai)式(shi)制(zhi)動(dong)(dong)器是(shi)因為其(qi)工(gong)作原理(li)而得名，在工(gong)作時是(shi)通過制(zhi)動(dong)(dong)塊(kuai)壓(ya)緊制(zhi)動(dong)(dong)輪來達到制(zhi)動(dong)(dong)目的(de)(de)的(de)(de)制(zhi)動(dong)(dong)器，今天要為大家介(jie)紹的(de)(de)是(shi)塊(kuai)式(shi)制(zhi)動(dong)(dong)器的(de)(de)結構與受(shou)力彎矩。根據塊(kuai)式(shi)制(zhi)動(dong)(dong)器的(de)(de)驅(qu)動(dong)(dong)器到制(zhi)動(dong)(dong)壁(bi)之間(jian)杠桿系(xi)統傳(chuan)動(dong)(dong)比大小(xiao)，塊(kuai)式(shi)制(zhi)動(dong)(dong)器分長行程(cheng)和短行程(cheng)兩種。前者杠桿系(xi)統傳(chuan)動(dong)(dong)比大，為了保(bao)證松閘時制(zhi)動(dong)(dong)瓦離開制(zhi)動(dong)(dong)輪有足(zu)夠的(de)(de)距離（退距），需要驅(qu)動(dong)(dong)裝置(zhi)有較長的(de)(de)工(gong)作行程(cheng)（一般在20mm以上）。
