1.隨車(che)(che)吊車(che)(che)輪的(de)受力(li)(li)分析主要從三個方面(mian)(mian)(mian)來(lai)講：地(di)(di)面(mian)(mian)(mian)制(zhi)(zhi)(zhi)動(dong)(dong)力(li)(li)、制(zhi)(zhi)(zhi)動(dong)(dong)器制(zhi)(zhi)(zhi)動(dong)(dong)力(li)(li)、地(di)(di)面(mian)(mian)(mian)制(zhi)(zhi)(zhi)動(dong)(dong)力(li)(li)，制(zhi)(zhi)(zhi)動(dong)(dong)器制(zhi)(zhi)(zhi)動(dong)(dong)力(li)(li)和附著力(li)(li)的(de)關系。首(shou)先，我(wo)們(men)來(lai)講一下(xia)地(di)(di)面(mian)(mian)(mian)制(zhi)(zhi)(zhi)動(dong)(dong)力(li)(li)，當拖車(che)(che)制(zhi)(zhi)(zhi)動(dong)(dong)時，由于制(zhi)(zhi)(zhi)動(dong)(dong)盤與制(zhi)(zhi)(zhi)動(dong)(dong)蹄摩(mo)擦(ca)片之(zhi)間(jian)的(de)摩(mo)擦(ca)作用，形成了摩(mo)擦(ca)力(li)(li)矩，此力(li)(li)矩與車(che)(che)輪轉動(dong)(dong)方向相反。車(che)(che)輪在摩(mo)擦(ca)力(li)(li)矩的(de)作用下(xia)給地(di)(di)面(mian)(mian)(mian)一個向前的(de)作用力(li)(li)，與此同時地(di)(di)面(mian)(mian)(mian)給車(che)(che)輪一個與行駛方向相反的(de)切向反作用力(li)(li)。

2.在隨(sui)車(che)吊制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器制(zhi)(zhi)(zhi)動(dong)(dong)(dong)力(li)(li)方(fang)面，當制(zhi)(zhi)(zhi)動(dong)(dong)(dong)時，阻止車(che)輪轉(zhuan)動(dong)(dong)(dong)的(de)是(shi)(shi)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器摩擦力(li)(li)矩(ju)。將制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器的(de)摩擦力(li)(li)矩(ju)轉(zhuan)化為車(che)輪周(zhou)緣的(de)一個切向力(li)(li)，稱(cheng)其為制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器制(zhi)(zhi)(zhi)動(dong)(dong)(dong)力(li)(li)。制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器制(zhi)(zhi)(zhi)動(dong)(dong)(dong)力(li)(li)是(shi)(shi)由制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器的(de)結構參(can)數決定的(de)，并與制(zhi)(zhi)(zhi)動(dong)(dong)(dong)踏板(ban)力(li)(li)成正比。要想(xiang)獲得好的(de)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)效果，必(bi)須同(tong)時具備兩個條件，即汽車(che)具有足夠的(de)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器制(zhi)(zhi)(zhi)動(dong)(dong)(dong)力(li)(li)，同(tong)時又要有附著系(xi)數較(jiao)高的(de)路面提高提供足夠的(de)地(di)面制(zhi)(zhi)(zhi)動(dong)(dong)(dong)力(li)(li)。

3.如果(guo)不考慮隨車(che)吊制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)過(guo)程中(zhong)附著(zhu)(zhu)系數(shu)變化(hua)的(de)(de)地面制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)力(li)(li)(li)(li)、制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)動(dong)(dong)(dong)(dong)力(li)(li)(li)(li)以及附著(zhu)(zhu)力(li)(li)(li)(li)三者的(de)(de)關系。拖車(che)在制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)過(guo)程中(zhong)，齒輪(lun)(lun)泵，車(che)輪(lun)(lun)的(de)(de)運動(dong)(dong)(dong)(dong)只有減速(su)(su)滾動(dong)(dong)(dong)(dong)和抱死滑移兩種狀態，當駕(jia)駛員踩制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)踏板的(de)(de)力(li)(li)(li)(li)較小，制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)摩擦(ca)力(li)(li)(li)(li)矩較小時，車(che)輪(lun)(lun)只作(zuo)減速(su)(su)滾動(dong)(dong)(dong)(dong)，并(bing)且隨著(zhu)(zhu)摩擦(ca)力(li)(li)(li)(li)矩的(de)(de)增加，制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)力(li)(li)(li)(li)地面制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)力(li)(li)(li)(li)也隨著(zhu)(zhu)增長(chang)，且在車(che)輪(lun)(lun)未(wei)抱死前地面制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)力(li)(li)(li)(li)始終等(deng)于制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)的(de)(de)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)力(li)(li)(li)(li)。此(ci)時，制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)的(de)(de)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)力(li)(li)(li)(li)可全(quan)部轉化(hua)為地面制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)力(li)(li)(li)(li)。但(dan)地面制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)力(li)(li)(li)(li)不可能超過(guo)附著(zhu)(zhu)力(li)(li)(li)(li)。

在(zai)所(suo)有(you)機(ji)構運行過(guo)程中，液(ye)(ye)(ye)壓(ya)系(xi)統起(qi)著至關重要的(de)作(zuo)用，液(ye)(ye)(ye)壓(ya)系(xi)統的(de)關鍵(jian)件包(bao)括(kuo)主(zhu)液(ye)(ye)(ye)壓(ya)泵、主(zhu)控制(zhi)閥、支腿(tui)操(cao)(cao)(cao)縱(zong)閥、主(zhu)副卷(juan)揚和(he)回轉(zhuan)減速機(ji)等，主(zhu)液(ye)(ye)(ye)壓(ya)泵由底盤發動機(ji)驅動，主(zhu)控制(zhi)閥分別控制(zhi)回轉(zhuan)、伸縮(suo)、變(bian)幅及卷(juan)揚作(zuo)業(ye)動作(zuo)，齒輪(lun)泵銷售，支腿(tui)操(cao)(cao)(cao)縱(zong)閥通過(guo)底盤單(dan)側或(huo)兩(liang)側操(cao)(cao)(cao)縱(zong)桿控制(zhi)支腿(tui)同時或(huo)單(dan)獨工作(zuo)。上(shang)車(che)操(cao)(cao)(cao)縱(zong)方式有(you)手柄操(cao)(cao)(cao)作(zuo)和(he)電液(ye)(ye)(ye)先導(dao)控制(zhi)，電液(ye)(ye)(ye)先導(dao)控制(zhi)是目前國內為的(de)操(cao)(cao)(cao)縱(zong)方式。

到隨車吊為(wei)什么要保養(yang)，我(wo)們得先從車保養(yang)和修理的區(qu)別和關系說起(qi)。

保養與修理的關系

隨(sui)車(che)吊保養和(he)車(che)修理(li)(li)是密切相關的。修理(li)(li)中(zhong)(zhong)有(you)保養，保養中(zhong)(zhong)有(you)修理(li)(li)。在車(che)輛保養過程中(zhong)(zhong)可能發現某(mou)一部位或機件(jian)將要發生故障或損壞的前兆，因(yin)而可利用保養時(shi)機，對其進行修理(li)(li)。而在修理(li)(li)的過程中(zhong)(zhong)，對一些沒有(you)損壞的機件(jian)也要進行保養，這是很自(zi)然(ran)的事情。

因此，車保(bao)(bao)養和車修理(li)的(de)(de)關(guan)系是辯證的(de)(de)。在日常(chang)活動(dong)中，一定(ding)要處理(li)好兩(liang)者之間的(de)(de)關(guan)系，齒輪泵(beng)廠家，堅持以(yi)保(bao)(bao)養為重點，克(ke)服“重修輕保(bao)(bao)”“以(yi)修代保(bao)(bao)”的(de)(de)不良傾向。“三分修七分養”說的(de)(de)就是這(zhe)個道理(li)。

車(che)養護(hu)中心針對目前(qian)車(che)養護(hu)行(xing)業中的(de)情況，科學的(de)將車(che)保養系(xi)統(tong)分為六大部分，并可對下(xia)列的(de)六大系(xi)統(tong)進(jin)行(xing)特(te)別養護(hu)。3噸(dun)(dun)隨車(che)吊(diao)(diao)，3.2噸(dun)(dun)隨車(che)吊(diao)(diao)，5噸(dun)(dun)隨車(che)吊(diao)(diao)，齒輪泵生產(chan)廠家(jia)，6.3噸(dun)(dun)隨車(che)吊(diao)(diao)，8噸(dun)(dun)隨車(che)吊(diao)(diao)，10噸(dun)(dun)隨車(che)吊(diao)(diao)。
