起動繼電器簡介

起動繼電器：保護線路，點(dian)火開關。

汽車啟動繼電器的作(zuo)用：

1、主要是通過控制低壓(ya)線(xian)(xian)路(lu)的(de)(de)電流(liu)來(lai)控制高壓(ya)線(xian)(xian)路(lu)的(de)(de)電流(liu)，起到(dao)電流(liu)開關的(de)(de)作(zuo)用。啟動(dong)繼電器(qi)是啟動(dong)系統組成部件(jian)之一，在汽(qi)車上主要作(zuo)用為小電流(liu)；

2、控制(zhi)大電(dian)(dian)流方式啟(qi)動馬(ma)達轉(zhuan)動，從而帶動發電(dian)(dian)機內部磁電(dian)(dian)機轉(zhuan)子轉(zhuan)動，給點火(huo)器(qi)輸入點火(huo)脈沖信號，使(shi)點火(huo)器(qi)產(chan)生(sheng)電(dian)(dian)火(huo)花，點燃(ran)汽缸內的混合(he)燃(ran)氣并做功(gong)。繼電(dian)(dian)器(qi)屬于開關類，它是利用電(dian)(dian)磁原(yuan)理、機電(dian)(dian)原(yuan)理使(shi)接點閉合(he)或斷開來驅動或控制(zhi)相關電(dian)(dian)路的；

3、繼電(dian)(dian)器(qi)為一種控(kong)(kong)制(zhi)器(qi)件，它有(you)受控(kong)(kong)系統(tong)（輸入回(hui)路）和(he)控(kong)(kong)制(zhi)系統(tong)（輸出回(hui)路）兩部分(fen)。當(dang)輸入量(liang)（電(dian)(dian)、磁、光(guang)、熱等物理量(liang)）達到某一定(ding)值(zhi)(zhi)時，輸出量(liang)躍變(bian)式地由零變(bian)化到一定(ding)值(zhi)(zhi)（或由一定(ding)值(zhi)(zhi)跳(tiao)變(bian)到零），從而(er)實現對電(dian)(dian)路的(de)控(kong)(kong)制(zhi)、保護、調節和(he)傳遞信(xin)息等目的(de)。

啟(qi)動(dong)(dong)繼電(dian)(dian)(dian)器是(shi)單(dan)(dan)獨部件(jian)，其(qi)作用(yong)是(shi)接通(tong)、斷開(kai)吸(xi)引線圈(quan)和保持線圈(quan)電(dian)(dian)(dian)路。在(zai)電(dian)(dian)(dian)冰箱、空(kong)調器這類小型(xing)制(zhi)冷(leng)設備中，制(zhi)冷(leng)壓(ya)縮(suo)機多采用(yong)單(dan)(dan)相分(fen)相式異步電(dian)(dian)(dian)動(dong)(dong)機，啟(qi)動(dong)(dong)繼電(dian)(dian)(dian)器的作用(yong)是(shi)幫助電(dian)(dian)(dian)動(dong)(dong)機啟(qi)動(dong)(dong)，啟(qi)動(dong)(dong)完成(cheng)后自動(dong)(dong)斷開(kai)副繞(rao)組，避免燒壞副繞(rao)組線圈(quan)。

金冠簡介

承襲梅賽德斯-奔馳對安全(quan)的(de)極致追求，6個安全(quan)氣囊全(quan)面(mian)保障駕(jia)駛(shi)員的(de)安全(quan)，配備注(zhu)意(yi)力輔助系(xi)統(tong)(tong)、主(zhu)動(dong)駐車(che)輔助系(xi)統(tong)(tong)、碰(peng)撞預防(fang)輔助系(xi)統(tong)(tong)增強版等，為駕(jia)駛(shi)者(zhe)提供支(zhi)持以減輕他們(men)的(de)駕(jia)駛(shi)強度。值得一提的(de)是(shi)，國(guo)產(chan)GLA 還搭(da)載了盲(mang)點輔助系(xi)統(tong)(tong)、主(zhu)動(dong)駐車(che)輔助系(xi)統(tong)(tong)，為駕(jia)乘帶(dai)來(lai)更多便利。
