起動繼電器簡介

起動繼(ji)電器：保護線路，點(dian)火開關。

汽車啟動繼電(dian)器的作用：

1、主要是通過控制(zhi)低壓線路(lu)(lu)的電流(liu)來控制(zhi)高壓線路(lu)(lu)的電流(liu)，起(qi)到電流(liu)開關(guan)的作(zuo)用(yong)。啟動繼電器是啟動系統組成部件之一(yi)，在汽(qi)車(che)上主要作(zuo)用(yong)為(wei)小電流(liu)；

2、控制(zhi)大電(dian)(dian)流方式(shi)啟動(dong)(dong)馬達轉(zhuan)動(dong)(dong)，從而帶(dai)動(dong)(dong)發(fa)電(dian)(dian)機(ji)內部磁電(dian)(dian)機(ji)轉(zhuan)子轉(zhuan)動(dong)(dong)，給點(dian)火(huo)(huo)器輸(shu)入(ru)點(dian)火(huo)(huo)脈沖信(xin)號，使(shi)(shi)點(dian)火(huo)(huo)器產生(sheng)電(dian)(dian)火(huo)(huo)花(hua)，點(dian)燃(ran)(ran)汽缸內的混合燃(ran)(ran)氣并(bing)做(zuo)功。繼電(dian)(dian)器屬(shu)于開(kai)關(guan)類(lei)，它是利用電(dian)(dian)磁原理、機(ji)電(dian)(dian)原理使(shi)(shi)接點(dian)閉合或(huo)斷開(kai)來驅動(dong)(dong)或(huo)控制(zhi)相關(guan)電(dian)(dian)路(lu)的；

3、繼電器(qi)為一種控(kong)制器(qi)件，它(ta)有受(shou)控(kong)系統（輸(shu)(shu)入回(hui)路(lu)(lu)）和控(kong)制系統（輸(shu)(shu)出回(hui)路(lu)(lu)）兩部分(fen)。當輸(shu)(shu)入量(liang)（電、磁、光、熱等(deng)物理量(liang)）達到(dao)某一定(ding)值時，輸(shu)(shu)出量(liang)躍變(bian)(bian)式地由(you)零變(bian)(bian)化(hua)到(dao)一定(ding)值（或由(you)一定(ding)值跳變(bian)(bian)到(dao)零），從(cong)而實現對電路(lu)(lu)的(de)控(kong)制、保護、調節和傳(chuan)遞信息等(deng)目(mu)的(de)。

啟(qi)(qi)動繼(ji)電(dian)(dian)器是單(dan)獨部件，其作用(yong)是接通、斷開吸引線(xian)圈(quan)和保持線(xian)圈(quan)電(dian)(dian)路。在(zai)電(dian)(dian)冰箱、空調器這類(lei)小型制(zhi)冷設備中，制(zhi)冷壓縮機多采(cai)用(yong)單(dan)相分(fen)相式異步電(dian)(dian)動機，啟(qi)(qi)動繼(ji)電(dian)(dian)器的作用(yong)是幫(bang)助(zhu)電(dian)(dian)動機啟(qi)(qi)動，啟(qi)(qi)動完成后自動斷開副(fu)繞(rao)組，避免燒壞副(fu)繞(rao)組線(xian)圈(quan)。

奧迪A6簡介

奧(ao)迪A6（Audi A6）是一(yi)款(kuan)由奧(ao)迪生產的(de)(de)豪華汽車(che)(che)，有轎(jiao)車(che)(che)和旅行車(che)(che)兩種車(che)(che)型。奧(ao)迪A6的(de)(de)multitronic無(wu)級(ji)/手動(dong)(dong)(dong)(dong)(dong)一(yi)體(ti)式(shi)變(bian)(bian)速箱(xiang)，在豪華轎(jiao)車(che)(che)歷史上，第(di)一(yi)次實(shi)現了真正的(de)(de)無(wu)級(ji)變(bian)(bian)速。它(ta)采用(yong)金屬(shu)鏈傳動(dong)(dong)(dong)(dong)(dong)方式(shi)，徹底取代了傳統的(de)(de)齒輪(lun)組變(bian)(bian)速方式(shi)，所以(yi)動(dong)(dong)(dong)(dong)(dong)力輸出全(quan)無(wu)頓(dun)挫感，比普通自動(dong)(dong)(dong)(dong)(dong)變(bian)(bian)速更(geng)(geng)順暢平滑，更(geng)(geng)擁有手動(dong)(dong)(dong)(dong)(dong)變(bian)(bian)速般的(de)(de)快(kuai)捷(jie)靈敏，同時(shi)還更(geng)(geng)節省燃油(you)，操控更(geng)(geng)舒適。新(xin)增設的(de)(de)S檔(dang)，提高加速能(neng)力，增加駕駛(shi)樂趣。multitronic無(wu)級(ji)/手動(dong)(dong)(dong)(dong)(dong)一(yi)體(ti)式(shi)變(bian)(bian)速箱(xiang)的(de)(de)最(zui)迷人之處，就(jiu)在于它(ta)最(zui)終(zhong)克服了自動(dong)(dong)(dong)(dong)(dong)變(bian)(bian)速箱(xiang)和手動(dong)(dong)(dong)(dong)(dong)變(bian)(bian)速箱(xiang)的(de)(de)一(yi)切不(bu)足，一(yi)舉超越二者的(de)(de)各(ge)項性能(neng)，實(shi)現了汽車(che)(che)變(bian)(bian)速箱(xiang)技術的(de)(de)大飛躍。
