2、現(xian)有雙(shuang)(shuang)電(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)驅(qu)(qu)橋,大(da)(da)都為單(dan)擋(dang)(dang)或(huo)兩擋(dang)(dang)結構,雖然能降低對高性能電(dian)(dian)(dian)(dian)機(ji)的需求,但總成(cheng)占(zhan)(zhan)用空(kong)(kong)間(jian)(jian)大(da)(da)(例如申(shen)請(qing)號為202311731737.6,公開號:cn117755069a,名稱為一種電(dian)(dian)(dian)(dian)驅(qu)(qu)橋系統及其工作方(fang)法的中國發明專利申(shen)請(qing),就是一種雙(shuang)(shuang)電(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)驅(qu)(qu)橋,通過換(huan)擋(dang)(dang)機(ji)構一和換(huan)擋(dang)(dang)機(ji)構二進行換(huan)擋(dang)(dang),總成(cheng)占(zhan)(zhan)用空(kong)(kong)間(jian)(jian)相對比較大(da)(da)),無法適應(ying)動(dong)力(li)電(dian)(dian)(dian)(dian)池的更大(da)(da)容量(liang)/空(kong)(kong)間(jian)(jian)布(bu)置(zhi)。同(tong)時,在(zai)(zai)匹(pi)配6x4車(che)型(xing)時,雙(shuang)(shuang)驅(qu)(qu)動(dong)橋各布(bu)置(zhi)兩個電(dian)(dian)(dian)(dian)機(ji),共計四(si)個電(dian)(dian)(dian)(dian)機(ji),再加上與之匹(pi)配的電(dian)(dian)(dian)(dian)機(ji)控制(zhi)器,造成(cheng)整車(che)成(cheng)本高昂,電(dian)(dian)(dian)(dian)驅(qu)(qu)動(dong)橋系統所(suo)占(zhan)(zhan)空(kong)(kong)間(jian)(jian)較大(da)(da),在(zai)(zai)市場上毫無競爭力(li)。

3、現(xian)有技(ji)術中(zhong)也出現(xian)了(le)單電機多(duo)擋(三擋或四(si)擋)的(de)電驅橋方(fang)案,但軸向占用空間大,不能滿足不同車(che)架寬度的(de)車(che)型(xing),適配(pei)性差。
