一、三輪電車有電不走了怎么回事
三輪電車既輕便、又(you)環(huan)保節能,是農(nong)村中(zhong)非常好的(de)一(yi)種(zhong)交通(tong)工(gong)具,但(dan)是在使用的(de)時(shi)候,難(nan)免(mian)會遇到(dao)一(yi)些問題(ti),如出現有(you)電不(bu)走了的(de)情況(kuang),那么這是怎么回事呢?
1、制動原因
所有的三輪電車都有手剎,所以你一拉手剎,車肯定就不走了。此外,三個車輪大部分都有剎車斷電功能。一旦三輪電車剎車失靈,比如剎車不回來,剎車斷電起作用,三(san)輪電(dian)車沒有(you)電源就走不了路。
2、轉動手柄的原因
三(san)輪(lun)電(dian)車的(de)把手(shou)(shou)一(yi)般衍生出五根電(dian)線(xian)(xian)(xian)(xian)(xian),紅(hong)線(xian)(xian)(xian)(xian)(xian)、黑線(xian)(xian)(xian)(xian)(xian)、藍線(xian)(xian)(xian)(xian)(xian)是手(shou)(shou)柄(bing)線(xian)(xian)(xian)(xian)(xian),另外兩根是換(huan)向(xiang)線(xian)(xian)(xian)(xian)(xian)。使用(yong)萬(wan)用(yong)表檢測(ce)下手(shou)(shou)柄(bing)兩根導線(xian)(xian)(xian)(xian)(xian)間的(de)電(dian)壓。然后轉動手(shou)(shou)柄(bing),如果(guo)紅(hong)線(xian)(xian)(xian)(xian)(xian)和黑線(xian)(xian)(xian)(xian)(xian)的(de)電(dian)壓不變(bian),再測(ce)量(liang)黑線(xian)(xian)(xian)(xian)(xian)和信(xin)號線(xian)(xian)(xian)(xian)(xian)。最后,轉動手(shou)(shou)柄(bing)。如果(guo)電(dian)壓從0.8變(bian)化到4.2,則可以判斷手(shou)(shou)柄(bing)正常。
相反,如(ru)果手柄(bing)壞了,還有更快(kuai)的(de)方法。從控(kong)制器上找到(dao)手柄(bing)線,用手柄(bing)試(shi)了一(yi)下(xia),直接連(lian)上,表示(shi)手柄(bing)可能斷了。然后(hou),找到(dao)通向前(qian)方的(de)連(lian)接器,最后(hou),轉(zhuan)動手柄(bing)試(shi)一(yi)試(shi)。如(ru)果手柄(bing)壞了,如(ru)果不轉(zhuan),說明手柄(bing)中間手柄(bing)線開路,請更換。
3、電機原因
電機(ji)的霍爾經(jing)常壞。一旦大(da)廳出現(xian)問題(ti),工(gong)作時汽車可能會(hui)癱(tan)瘓或(huo)顫抖。如果電機(ji)的相線(xian)和霍爾線(xian)與控(kong)制器(qi)連接良好(hao),請(qing)打開電源(yuan)鎖打開控(kong)制器(qi),將萬(wan)用表(biao)調到DC+20V位置。
將萬用(yong)表(biao)黑色指針接到霍(huo)爾(er)(er)負極線(xian)上。用(yong)紅(hong)筆檢測(ce)電機(ji)三條霍(huo)爾(er)(er)線(xian)的電壓。測(ce)量三條霍(huo)爾(er)(er)線(xian)時(shi),輕輕轉動電機(ji)輪,看萬用(yong)表(biao)電壓是否有0-5伏的變化(hua)。如果沒有變化(hua),說明對應的霍(huo)爾(er)(er)元件有故(gu)障或者霍(huo)爾(er)(er)線(xian)開路(lu),更換;否則,霍(huo)爾(er)(er)元件正常。
4、控制器問題
控制(zhi)(zhi)器(qi)(qi)損(sun)壞,會導(dao)致電(dian)動(dong)(dong)車(che)跑(pao)不動(dong)(dong)或者運行速(su)度慢的情況。控制(zhi)(zhi)器(qi)(qi)是(shi)(shi)電(dian)動(dong)(dong)自行車(che)的驅(qu)動(dong)(dong)系(xi)統,是(shi)(shi)電(dian)動(dong)(dong)汽車(che)的核心部件。它(ta)的主要作(zuo)用(yong)是(shi)(shi)控制(zhi)(zhi)電(dian)機(ji)的轉(zhuan)速(su),控制(zhi)(zhi)器(qi)(qi)配(pei)合(he)調速(su)手柄控制(zhi)(zhi)電(dian)機(ji)的轉(zhuan)速(su),并能(neng)(neng)隨著制(zhi)(zhi)動(dong)(dong)開(kai)關的閉(bi)合(he)而關閉(bi)電(dian)機(ji)。如果控制(zhi)(zhi)器(qi)(qi)損(sun)壞,只能(neng)(neng)更換。
二、三輪電車常見故障及維修
1、整車沒電:檢查電(dian)源(yuan)是(shi)否(fou)充(chong)滿電(dian);保(bao)險(xian)絲(si)是(shi)否(fou)熔斷,更(geng)換保(bao)險(xian)絲(si);電(dian)源(yuan)鎖是(shi)否(fou)燒壞(huai),檢查并更(geng)換;查看內部電(dian)極連線是(shi)否(fou)松(song)動,按照要求連接。
2、有電不走:一般是(shi)(shi)(shi)電池連(lian)線問題,或(huo)者(zhe)剎車抱死,先查看(kan)剎把是(shi)(shi)(shi)否斷開,如果(guo)是(shi)(shi)(shi)需要用(yong)手(shou)頂住即可行駛,如果(guo)還不行要及時維修。
3、耗電大車沒勁:電池(chi)(chi)損壞,胎(tai)壓不足,更換電池(chi)(chi)即(ji)可(ke)。如果騎行(xing)噪音大(da)有頓挫感是因為控制器(qi)(qi)和電機的匹配有問題,處理方法(fa)是更換匹配的控制器(qi)(qi)。
4、推車有阻力:如果(guo)推(tui)車有(you)阻力可(ke)能是mos管損壞需要更換控制器。
5、充電器插電跳綠燈:一般(ban)是(shi)充電(dian)(dian)器的電(dian)(dian)壓較低,導致電(dian)(dian)池充電(dian)(dian)不足(zu),需要修(xiu)復充電(dian)(dian)器,或者是(shi)電(dian)(dian)池功能衰退,更換修(xiu)復電(dian)(dian)池即可。
