汽車輔助電氣系統的作用
汽(qi)車(che)輔(fu)助電(dian)器(qi)(qi)系統主要向舒適、娛樂、保障安(an)全等(deng)方面(mian)發展。汽(qi)車(che)上的輔(fu)助電(dian)器(qi)(qi)除汽(qi)車(che)用音響設備、通信器(qi)(qi)材和(he)汽(qi)車(che)電(dian)視等(deng)服務性(xing)裝置外,都是一些與(yu)汽(qi)車(che)本(ben)身使用性(xing)能有關的電(dian)器(qi)(qi)設備。
汽車輔助電氣系統有哪些
汽(qi)車輔助電(dian)(dian)氣系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)包括照明與信號系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、電(dian)(dian)控車窗系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、中央(yang)門鎖系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、電(dian)(dian)控后視鏡(jing)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、電(dian)(dian)控座椅系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、儀(yi)表、報(bao)警(jing)及電(dian)(dian)子顯示系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、刮水器(qi)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)。
汽車輔助電氣系統故障診斷與維修
1、電器設備故障
電器設備故障是指電器設備自身喪失其原有機能,包括電器設備的機械損壞、燒毀、電子元件的擊穿、老(lao)化、性能減退等(deng)。
在實(shi)際使用(yong)和維修中,常常因線路故(gu)障而(er)造(zao)成(cheng)電器設備故(gu)障。
注意:電(dian)器設備故(gu)障一般(ban)是(shi)可修復的(de)(de),但(dan)一些不(bu)可拆的(de)(de)電(dian)子設備出現故(gu)障后只能更換。
2、線路故障
線路故障包括斷路、短(duan)路、接(jie)線松脫、接(jie)觸不良或絕緣不良等。
這一類(lei)故障有時(shi)容(rong)易出現一些假象(xiang),給故障診斷(duan)帶來困難。必要時(shi)可以(yi)參考電路圖(tu)排(pai)查解決。
