盤式製動器定義

    盤式製動器

    有鉗盤式和全盤式兩種

，前者更為常用。鉗盤式製動器的特點是：摩(mo)擦(ca)副(fu)中(zhong)的(de)旋(xuan)轉(zhuan)元(yuan)件(jian)是(shi)製(zhi)動(dong)盤(pan)，製(zhi)動(dong)盤(pan)與(yu)車(che)輪(lun)輪(lun)轂(gu)一(yi)同(tong)旋(xuan)轉(zhuan)，以(yi)兩(liang)端(duan)麵(mian)為(wei)工(gong)作(zuo)表(biao)麵(mian)，固(gu)定(ding)元(yuan)件(jian)是(shi)製(zhi)動(dong)鉗(qian)，製(zhi)動(dong)鉗(qian)在(zai)製(zhi)動(dong)輪(lun)缸(gang)作(zuo)用(yong)下(xia)將(jiang)製(zhi)動(dong)塊(kuai)壓(ya)向(xiang)製(zhi)動(dong)盤(pan)
，從(cong)而(er)產(chan)生(sheng)製(zhi)動(dong)摩(mo)擦(ca)力(li)矩(ju)。鉗(qian)盤(pan)式(shi)製(zhi)動(dong)器(qi)廣(guang)泛(fan)用(yong)於(yu)乘(cheng)用(yong)車(che)和(he)輕(qing)型(xing)客(ke)車(che)。

    盤式製動器有液壓型的，由液壓控製，主要零部件有製動盤
、分泵

、製動鉗
、油you管guan等deng。製zhi動dong盤pan用yong合he金jin鋼gang製zhi造zao並bing固gu定ding在zai車che輪lun上shang，隨sui車che輪lun轉zhuan動dong。分fen泵beng固gu定ding在zai製zhi動dong器qi的de底di板ban上shang固gu定ding不bu動dong，製zhi動dong鉗qian上shang的de兩liang個ge摩mo擦ca片pian分fen別bie裝zhuang在zai製zhi動dong盤pan的de兩liang側ce，分fen泵beng的de活huo塞sai受shou油you管guan輸shu送song來lai的de液ye壓ya作zuo用yong

、重量輕、構造簡單
、調整方便。很多轎車采用的盤式製動器有平麵式製動盤、打孔式製動盤以及劃線式製動盤，其中劃線式製動盤的製動效果和通風散熱能力均比較好。

    盤式製動器沿製動盤向施力
，製動軸不受彎矩

，徑向尺寸小，製動性能穩定。

    盤(pan)式(shi)製(zhi)動(dong)器(qi)摩(mo)擦(ca)副(fu)中(zhong)的(de)旋(xuan)轉(zhuan)元(yuan)件(jian)是(shi)以(yi)端(duan)麵(mian)工(gong)作(zuo)的(de)金(jin)屬(shu)圓(yuan)盤(pan)，被(bei)稱(cheng)為(wei)製(zhi)動(dong)盤(pan)。其(qi)固(gu)定(ding)元(yuan)件(jian)則(ze)有(you)著(zhe)多(duo)種(zhong)結(jie)構(gou)型(xing)式(shi)，大(da)體(ti)上(shang)可(ke)分(fen)為(wei)兩(liang)類(lei)。一(yi)類(lei)是(shi)工(gong)作(zuo)麵(mian)積(ji)不(bu)大(da)的(de)摩(mo)擦(ca)塊(kuai)與(yu)其(qi)金(jin)屬(shu)背(bei)板(ban)組(zu)成(cheng)的(de)製(zhi)動(dong)塊(kuai)，每(mei)個(ge)製(zhi)動(dong)器(qi)中(zhong)有(you)2～4個ge。這zhe些xie製zhi動dong塊kuai及ji其qi促cu動dong裝zhuang置zhi都dou裝zhuang在zai橫heng跨kua製zhi動dong盤pan兩liang側ce的de夾jia鉗qian形xing支zhi架jia中zhong，總zong稱cheng為wei製zhi動dong鉗qian。這zhe種zhong由you製zhi動dong盤pan和he製zhi動dong鉗qian組zu成cheng的de製zhi動dong器qi稱cheng為wei鉗qian盤pan式shi製zhi動dong器qi。另ling一yi類lei固gu定ding元yuan件jian的de金jin屬shu背bei板ban和he摩mo擦ca片pian也ye呈cheng圓yuan盤pan形xing，製zhi動dong盤pan的de全quan部bu工gong作zuo麵mian可ke同tong時shi與yu摩mo擦ca片pian接jie觸chu，這zhe種zhong製zhi動dong器qi稱cheng為wei全quan盤pan式shi製zhi動dong器qi。鉗qian盤pan式shi製zhi動dong器qi過guo去qu隻zhi用yong作zuo中zhong央yang製zhi動dong器qi，但dan則ze愈yu來lai愈yu多duo地di被bei各ge級ji轎jiao車che和he貨huo車che用yong作zuo車che輪lun製zhi動dong器qi。全quan盤pan式shi製zhi動dong器qi隻zhi有you少shao數shu汽qi車che(主要是重型汽車)采用為車輪製動器。這裏隻介紹鉗盤式製動器。鉗盤式製動器又可分為定鉗盤式和浮鉗盤式兩類。
