制動器維護注意事項
制動器是具有使運動部件（或運動機械）減速、停止或保持停止狀態等功能的裝置。是使機械中的運動件停止或減速的機械零件。是利用摩擦力矩降低機器運動部件的轉速或使其停止回轉的裝置。
制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)器工作(zuo)原理(li)：當(dang)施(shi)加制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)時，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)踏板作(zuo)用(yong)力(li)(li)經真空助力(li)(li)器助力(li)(li)后傳(chuan)遞到制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)主缸。制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)主缸將液(ye)壓(ya)(ya)油壓(ya)(ya)送入(ru)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)管和制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)軟(ruan)管，在(zai)液(ye)壓(ya)(ya)壓(ya)(ya)力(li)(li)的(de)作(zuo)用(yong)下，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)輪缸活塞(sai)推動(dong)(dong)(dong)(dong)(dong)(dong)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)蹄外(wai)張，使(shi)之與(yu)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)鼓(gu)接觸(chu)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)蹄與(yu)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)鼓(gu)之間的(de)摩(mo)擦(ca)力(li)(li)迫使(shi)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)鼓(gu)的(de)轉(zhuan)速(su)下降，從(cong)而降低(di)車速(su)，最終使(shi)車輛停止行駛。當(dang)解(jie)除制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)時，液(ye)壓(ya)(ya)系統的(de)液(ye)壓(ya)(ya)壓(ya)(ya)力(li)(li)下降，在(zai)回位彈簧的(de)作(zuo)用(yong)下，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)輪缸活塞(sai)回位，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)蹄與(yu)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)鼓(gu)分離，兩者間的(de)摩(mo)擦(ca)力(li)(li)消失。
制動器設備必須滿(man)足的條件(jian)：
1、能產(chan)生足夠胡制動力矩。
2、結構簡單，外(wai)形緊湊。調整、維修方便(bian)。
3、制動(dong)迅速(su)、平穩、可靠。
4、零件有足夠(gou)的(de)(de)強度(du)和(he)剛度(du)，制(zhi)動(dong)帶、鼓應具有較高的(de)(de)耐(nai)磨性和(he)耐(nai)熱性。
制動器維(wei)護注意事項：
1、需(xu)要經(jing)常在設備的可動部分添加潤(run)滑(hua)劑。
2、檢修要點定期檢查(cha)銜鐵(tie)行程的長度。
3、如(ru)果更換了(le)磨損(sun)的(de)制動(dong)面，應(ying)重新適當調整制動(dong)面與轉(zhuan)盤之間的(de)至小間隙(xi)。
4、定(ding)期檢查可動部(bu)件的機械(xie)磨損情況，并清掉(diao)電磁鐵零(ling)件表面的灰塵，花毛和污垢。
