蘇(su)州和上(shang)海2018年11月23日電(dian)(dian) /美通社/ -- 在“2018舍弗勒大中(zhong)華區技術(shu)研討會”期間，新(xin)成立的(de)電(dian)(dian)驅動(dong)(dong)業務部展示了針對未來電(dian)(dian)動(dong)(dong)車及混(hun)(hun)合動(dong)(dong)力車應用的(de)創(chuang)新(xin)解決方案(an)，包(bao)括集(ji)成了三(san)離合器的(de)超(chao)緊湊型混(hun)(hun)合動(dong)(dong)力模塊(kuai)、新(xin)一代電(dian)(dian)驅動(dong)(dong)橋(qiao)以(yi)及專用混(hun)(hun)動(dong)(dong)變速箱。

未來十年，全球主要汽(qi)車(che)(che)市場對(dui)二氧化碳排放的(de)限制(zhi)(zhi)將進一步加(jia)強。比(bi)如說(shuo)，歐盟計劃到2030年，將2021年每公里(li)95g的(de)汽(qi)車(che)(che)碳排放目(mu)標(biao)再降低(di)30%。中國市場也(ye)針對(dui)新能(neng)源汽(qi)車(che)(che)出(chu)臺(tai)了許(xu)多不(bu)同(tong)(tong)(tong)的(de)政策。考慮到各(ge)國法(fa)規要求和客戶(hu)偏好各(ge)不(bu)相同(tong)(tong)(tong)，舍弗(fu)勒新成(cheng)(cheng)立的(de)電(dian)驅動(dong)業務部(bu)可針對(dui)各(ge)種需求提供不(bu)同(tong)(tong)(tong)的(de)驅動(dong)解決(jue)方(fang)案。此外，為了幫(bang)助汽(qi)車(che)(che)制(zhi)(zhi)造(zao)商降低(di)電(dian)動(dong)車(che)(che)及混合動(dong)力車(che)(che)的(de)成(cheng)(cheng)本，這些(xie)解決(jue)方(fang)案的(de)電(dian)子(zi)電(dian)氣零(ling)部(bu)件(jian)都(dou)采(cai)用了相同(tong)(tong)(tong)的(de)開發平(ping)臺(tai)。該平(ping)臺(tai)包括硬件(jian)部(bu)分比(bi)如電(dian)機和功率電(dian)子(zi)零(ling)部(bu)件(jian)，還包括用于控(kong)制(zhi)(zhi)驅動(dong)裝置的(de)關鍵軟件(jian)模塊。

舍(she)(she)弗(fu)勒(le)憑借(jie)雙(shuang)離(li)(li)合(he)(he)器(qi)和(he)(he)可(ke)用于混(hun)(hun)(hun)合(he)(he)動(dong)(dong)力(li)(li)車的(de)混(hun)(hun)(hun)合(he)(he)動(dong)(dong)力(li)(li)模(mo)(mo)塊(kuai)(kuai)已經取得了巨(ju)大(da)的(de)市場成(cheng)(cheng)功。在(zai)這種被稱為“P2架構(gou)”的(de)混(hun)(hun)(hun)合(he)(he)動(dong)(dong)力(li)(li)方(fang)案中(zhong)，電(dian)(dian)機(ji)(ji)位于發動(dong)(dong)機(ji)(ji)和(he)(he)變速箱中(zhong)間(jian)。在(zai)目(mu)前的(de)第二代(dai)混(hun)(hun)(hun)合(he)(he)動(dong)(dong)力(li)(li)模(mo)(mo)塊(kuai)(kuai)中(zhong)，舍(she)(she)弗(fu)勒(le)已經成(cheng)(cheng)功將分離(li)(li)離(li)(li)合(he)(he)器(qi)集(ji)(ji)成(cheng)(cheng)到(dao)(dao)了電(dian)(dian)機(ji)(ji)中(zhong)。該離(li)(li)合(he)(he)器(qi)負責切斷電(dian)(dian)機(ji)(ji)與發動(dong)(dong)機(ji)(ji)的(de)連(lian)接，從而實(shi)現純電(dian)(dian)行(xing)駛。在(zai)本(ben)次研(yan)討(tao)會上，舍(she)(she)弗(fu)勒(le)展示了第三(san)(san)代(dai)混(hun)(hun)(hun)合(he)(he)動(dong)(dong)力(li)(li)模(mo)(mo)塊(kuai)(kuai)。在(zai)新的(de)模(mo)(mo)塊(kuai)(kuai)中(zhong)，整套雙(shuang)離(li)(li)合(he)(he)器(qi)被集(ji)(ji)成(cheng)(cheng)到(dao)(dao)電(dian)(dian)機(ji)(ji)中(zhong) -- 更準確(que)地說，被集(ji)(ji)成(cheng)(cheng)到(dao)(dao)電(dian)(dian)機(ji)(ji)的(de)轉子中(zhong)。為保證結合(he)(he)力(li)(li)，第三(san)(san)代(dai)混(hun)(hun)(hun)合(he)(he)動(dong)(dong)力(li)(li)模(mo)(mo)塊(kuai)(kuai)采(cai)用了高(gao)性能跑車上標配的(de)多片離(li)(li)合(he)(he)器(qi)，同(tong)時搭配了同(tong)樣高(gao)度集(ji)(ji)成(cheng)(cheng)的(de)執行(xing)機(ji)(ji)構(gou)來驅動(dong)(dong)三(san)(san)個離(li)(li)合(he)(he)器(qi)。舍(she)(she)弗(fu)勒(le)打造了一(yi)款超緊湊型混(hun)(hun)(hun)合(he)(he)動(dong)(dong)力(li)(li)模(mo)(mo)塊(kuai)(kuai)，使整個動(dong)(dong)力(li)(li)總成(cheng)(cheng)的(de)長度非常(chang)緊湊，僅稍(shao)長于純內(nei)燃機(ji)(ji)版(ban)的(de)車型。

此(ci)外，隨著插電式混合(he)(he)動(dong)(dong)(dong)(dong)力汽車(che)市場份額的不斷增加，汽車(che)制造(zao)商開始重(zhong)新(xin)審視(shi)車(che)輛(liang)變(bian)(bian)(bian)(bian)速箱(xiang)(xiang)的設計(ji)。除(chu)了將電機(ji)放在變(bian)(bian)(bian)(bian)速箱(xiang)(xiang)的前面(mian)或(huo)后(hou)面(mian)，他們開始考慮將這(zhe)兩(liang)者組(zu)合(he)(he)成(cheng)一(yi)個(ge)(ge)整(zheng)體結(jie)構(gou)和功能(neng)單元。舍弗勒在本次研討會上(shang)展示了一(yi)個(ge)(ge)具有(you)革新(xin)意義(yi)的概(gai)(gai)念 -- “專用(yong)混動(dong)(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速箱(xiang)(xiang)”。這(zhe)種被稱為“DH-ST 6+2”的專用(yong)混動(dong)(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速箱(xiang)(xiang)基于(yu)機(ji)械式自動(dong)(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速箱(xiang)(xiang)（AMT）開發(fa)(fa)而成(cheng)，具有(you)兩(liang)個(ge)(ge)電機(ji)擋(dang)位和6個(ge)(ge)發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)擋(dang)位。與發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)并聯運(yun)行的電機(ji)被整(zheng)合(he)(he)到變(bian)(bian)(bian)(bian)速箱(xiang)(xiang)結(jie)構(gou)中，具有(you)兩(liang)個(ge)(ge)速比。這(zhe)種結(jie)構(gou)的優勢是可(ke)以(yi)(yi)大(da)大(da)提高電機(ji)在包括高車(che)速下的效率。發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)擁有(you)兩(liang)個(ge)(ge)獨(du)立(li)的擋(dang)位。在變(bian)(bian)(bian)(bian)速箱(xiang)(xiang)的兩(liang)個(ge)(ge)部(bu)分(fen)中間還有(you)一(yi)組(zu)“復合(he)(he)”齒輪(lun)，使發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)也能(neng)夠利(li)用(yong)電機(ji)部(bu)分(fen)的齒輪(lun)，這(zhe)樣就額外增加了兩(liang)個(ge)(ge)擋(dang)位。該概(gai)(gai)念通過兩(liang)次使用(yong)同一(yi)排齒輪(lun)，僅(jin)用(yong)5組(zu)齒輪(lun)便實(shi)現了6個(ge)(ge)發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)檔位。仿真結(jie)果表明，通過“DH-ST 6+2”專用(yong)混動(dong)(dong)(dong)(dong)變(bian)(bian)(bian)(bian)速箱(xiang)(xiang)不僅(jin)可(ke)以(yi)(yi)幫助(zhu)車(che)輛(liang)實(shi)現運(yun)動(dong)(dong)(dong)(dong)性(xing)能(neng)以(yi)(yi)及220kW的系統性(xing)能(neng)，還可(ke)以(yi)(yi)獲(huo)得較低的WLTC油耗，百公里僅(jin)為4.5L。

早在2011年，舍(she)(she)弗(fu)勒(le)就推出(chu)了(le)(le)一款概念車，在前后(hou)橋(qiao)(qiao)(qiao)(qiao)分別安裝了(le)(le)一個(ge)電(dian)(dian)(dian)(dian)驅(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)，同(tong)時還(huan)在兩個(ge)驅(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)上(shang)實現了(le)(le)扭(niu)矩(ju)矢(shi)(shi)量(liang)(liang)分配。之后(hou)，舍(she)(she)弗(fu)勒(le)不僅開(kai)(kai)始(shi)批量(liang)(liang)生產電(dian)(dian)(dian)(dian)驅(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)的(de)關鍵零部件(jian)，還(huan)開(kai)(kai)發(fa)了(le)(le)一個(ge)完整的(de)電(dian)(dian)(dian)(dian)驅(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)家族譜系。該譜系包括平行軸(zhou)式(shi)和(he)同(tong)軸(zhou)式(shi)電(dian)(dian)(dian)(dian)橋(qiao)(qiao)(qiao)(qiao)，可(ke)選擇搭配的(de)系統(tong)(tong)包括差速(su)器(qi)、可(ke)換擋的(de)兩擋變速(su)箱和(he)扭(niu)矩(ju)矢(shi)(shi)量(liang)(liang)分配單元。在本次研討(tao)會上(shang)，舍(she)(she)弗(fu)勒(le)通(tong)過一款新(xin)的(de)產品概念向客(ke)戶(hu)展示，未來(lai)如何(he)根據空間(jian)要求、駕(jia)駛性能和(he)功(gong)能來(lai)定制化開(kai)(kai)發(fa)電(dian)(dian)(dian)(dian)驅(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)，滿足電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車和(he)混合動(dong)(dong)(dong)力(li)車的(de)應(ying)用需求。通(tong)過對比2011年和(he)新(xin)一代(dai)的(de)電(dian)(dian)(dian)(dian)驅(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)，可(ke)了(le)(le)解該產品在技術上(shang)取(qu)得(de)的(de)進步：第一代(dai)電(dian)(dian)(dian)(dian)驅(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)重達(da)90kg，較(jiao)大輸出(chu)功(gong)率(lv)為60kW，而最新(xin)一代(dai)電(dian)(dian)(dian)(dian)驅(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)的(de)較(jiao)大輸出(chu)功(gong)率(lv)高達(da)145kW，重量(liang)(liang)卻降低了(le)(le)10kg。“我們(men)從系統(tong)(tong)的(de)角度(du)出(chu)發(fa)來(lai)開(kai)(kai)發(fa)電(dian)(dian)(dian)(dian)驅(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)的(de)電(dian)(dian)(dian)(dian)氣、機(ji)械和(he)電(dian)(dian)(dian)(dian)子零部件(jian)，也只(zhi)有通(tong)過這(zhe)種方式(shi)，才能取(qu)得(de)這(zhe)一成果，”舍(she)(she)弗(fu)勒(le)汽車主機(ji)事業部首席執行官馬迪斯·青(qing)克解釋道。

“作(zuo)為(wei)各種形式電氣化解決方(fang)案的(de)開發合作(zuo)伙伴，舍弗勒提供豐富且全面(mian)的(de)產品和(he)技術，用(yong)于(yu)實現傳統動(dong)力總成系統電氣化。舉例(li)來說，針對P2混(hun)合動(dong)力解決方(fang)案，我們(men)提供的(de)模塊可以(yi)(yi)搭(da)配液力變(bian)(bian)矩(ju)器、無級變(bian)(bian)速(su)器和(he)雙離合器。在這(zhe)方(fang)面(mian)，舍弗勒擁有強大的(de)優勢，我們(men)在機械領域的(de)技術專長讓我們(men)的(de)客戶(hu)也從中受益，”青克先(xian)生補充道。“這(zhe)樣，我們(men)可以(yi)(yi)根據客戶(hu)不同(tong)的(de)要求(qiu)和(he)驅動(dong)需求(qiu)提供理想的(de)解決方(fang)案。”
