盤式制動器性能特點

　　盤式制動(dong)器性能特點

　　與鼓式制動器相比，盤式制動器工作表面為平面且兩面傳熱，圓盤旋轉容易(yi)冷卻，不易(yi)發(fa)生較大變(bian)形，制(zhi)(zhi)(zhi)動(dong)(dong)效能較為穩定，長時間(jian)(jian)使用后(hou)制(zhi)(zhi)(zhi)動(dong)(dong)盤因高(gao)溫(wen)膨脹(zhang)使制(zhi)(zhi)(zhi)動(dong)(dong)作用增強;而鼓(gu)(gu)(gu)式(shi)制(zhi)(zhi)(zhi)動(dong)(dong)器單面傳熱，內外兩面溫(wen)差較大，導致制(zhi)(zhi)(zhi)動(dong)(dong)鼓(gu)(gu)(gu)容易(yi)變(bian)形，同時長時間(jian)(jian)制(zhi)(zhi)(zhi)動(dong)(dong)后(hou)，制(zhi)(zhi)(zhi)動(dong)(dong)鼓(gu)(gu)(gu)因高(gao)溫(wen)而膨脹(zhang)，制(zhi)(zhi)(zhi)動(dong)(dong)效能減(jian)弱(ruo)。另外，盤式(shi)制(zhi)(zhi)(zhi)動(dong)(dong)器結(jie)構簡單，維修方便，易(yi)實現制(zhi)(zhi)(zhi)動(dong)(dong)間(jian)(jian)隙自動(dong)(dong)調整。

　　盤(pan)式制(zhi)動(dong)(dong)(dong)(dong)(dong)器(qi)的(de)不(bu)足之處(chu)在于摩擦片直接(jie)作用(yong)在圓盤(pan)上，無(wu)自動(dong)(dong)(dong)(dong)(dong)摩擦增力作用(yong)，制(zhi)動(dong)(dong)(dong)(dong)(dong)效能(neng)較低，所以用(yong)于液壓(ya)制(zhi)動(dong)(dong)(dong)(dong)(dong)系統時若所需(xu)制(zhi)動(dong)(dong)(dong)(dong)(dong)促動(dong)(dong)(dong)(dong)(dong)管(guan)路(lu)壓(ya)力較高(gao)，須另行裝(zhuang)設動(dong)(dong)(dong)(dong)(dong)力輔助裝(zhuang)置;兼用(yong)于駐車制(zhi)動(dong)(dong)(dong)(dong)(dong)時，加裝(zhuang)的(de)駐車制(zhi)動(dong)(dong)(dong)(dong)(dong)傳動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置比(bi)鼓式制(zhi)動(dong)(dong)(dong)(dong)(dong)器(qi)要復(fu)雜(za)，因而在后輪上的(de)應用(yong)受到(dao)***。
