無級(jí)變速拖拉機(jī)賽道之上,中外差距依然較大

2022-09-27 14:46:10 來源:農(nóng)機(jī)網(wǎng)整理發(fā)布 閱讀量:49400 評(píng)論

導(dǎo)讀:在我國(guó),動(dòng)力換擋、無級(jí)變速技術(shù),還屬于比較高端的技術(shù),僅有幾家大企業(yè)掌握并能夠產(chǎn)業(yè)化應(yīng)用。

  【農(nóng)機(jī)網(wǎng) 編輯視角】百余年來,隨著工業(yè)制造能力和科學(xué)技術(shù)的不斷發(fā)展,拖拉機(jī)技術(shù)已經(jīng)發(fā)生了翻天覆地的變化。變速箱作為拖拉機(jī)的主要部件之一,其技術(shù)已經(jīng)從最初的滑動(dòng)齒輪換擋、嚙合套換擋、同步器換擋到如今廣泛應(yīng)用的動(dòng)力換擋和無級(jí)變速。
 

 

  對(duì)于像約翰迪爾、凱斯、愛科這些世界級(jí)農(nóng)機(jī)巨頭來說,動(dòng)力換擋該技術(shù)已經(jīng)在其拖拉機(jī)上運(yùn)用得相當(dāng)成熟和廣泛。在我國(guó),動(dòng)力換擋、無級(jí)變速技術(shù),還屬于比較高端的技術(shù),僅有幾家大企業(yè)掌握并能夠產(chǎn)業(yè)化應(yīng)用,大部分拖拉機(jī)還是采用機(jī)械換擋。近年來,我國(guó)農(nóng)機(jī)企業(yè)也不甘示弱,力爭(zhēng)迎頭趕上。
 
  魯中拖拉機(jī)——近日,濰坊魯中拖拉機(jī)有限公司憑借功率合流無級(jí)變速拖拉機(jī)的研發(fā),成功入選2022年山東省首臺(tái)套技術(shù)裝備。據(jù)了解,該無級(jí)變速拖拉機(jī)采用了液壓機(jī)械功率合流傳動(dòng)技術(shù),具有較高的傳動(dòng)效率,更易于實(shí)現(xiàn)無人駕駛和智能操作。但首臺(tái)套的新裝備想要贏得市場(chǎng)的青睞,還要闖過用戶不信任、生產(chǎn)成本高、國(guó)際同行擠壓等多個(gè)難關(guān)。
 
  中聯(lián)重科——2022年8月8日,中聯(lián)重科宣布其PV1104動(dòng)力換向水田拖拉機(jī)在湖南常德正式下線,P系列動(dòng)力換擋拖拉機(jī)家族再添新成員。據(jù)中聯(lián)重科介紹,此次下線的PV1104采用的是其自主研發(fā)的動(dòng)力換向變速箱,換向操作簡(jiǎn)單高效。
 
  玉柴集團(tuán)——在近期玉柴展出的一批新的核心產(chǎn)品和技術(shù)創(chuàng)新成果中,玉柴芯藍(lán)非道路用拖拉機(jī)IE-Power動(dòng)力總成是眾人關(guān)注的焦點(diǎn)之一。它是中國(guó)首款拖拉機(jī)電驅(qū)無級(jí)變速動(dòng)力總成,是由玉柴完全自主研發(fā)的拖拉機(jī)用串聯(lián)式混合動(dòng)力總成技術(shù)解決方案,一款拖拉機(jī)電驅(qū)無級(jí)變速動(dòng)力總成,由發(fā)動(dòng)機(jī)、發(fā)電機(jī)、驅(qū)動(dòng)電機(jī)、電動(dòng)換檔變速箱組成,適配200~260馬力拖拉機(jī)。玉柴拖拉機(jī)IE-Power打破了國(guó)外CVT技術(shù)壟斷,填補(bǔ)了國(guó)內(nèi)技術(shù)空白。它以最簡(jiǎn)單高效的方式實(shí)現(xiàn)拖拉機(jī)無級(jí)變速功能。它采用高度技術(shù)集成設(shè)計(jì),關(guān)鍵部件模塊化,實(shí)現(xiàn)了拖拉機(jī)底盤升級(jí)。【詳情】
 
  中國(guó)一拖——東方紅 LW2304輪式拖拉機(jī)是2021年青島國(guó)際農(nóng)機(jī)展首次亮相的東方紅新品大馬力拖拉機(jī),它是中國(guó)一拖為國(guó)內(nèi)大型農(nóng)場(chǎng)及替代進(jìn)口需要而開發(fā)的具有完全自主知識(shí)產(chǎn)權(quán)的新一代無級(jí)變速重型輪式拖拉機(jī)。該產(chǎn)品為旱地農(nóng)業(yè)一般用途,特別適用于大型農(nóng)場(chǎng)的耕、耙、復(fù)式作業(yè)等重負(fù)荷作業(yè),可實(shí)現(xiàn)與其它農(nóng)機(jī)的聯(lián)合精準(zhǔn)作業(yè)。【詳情】
 
  濰柴雷沃——濰柴雷沃是濰柴集團(tuán)和雷沃重工戰(zhàn)略重組的“產(chǎn)品”。兩家企業(yè)強(qiáng)強(qiáng)聯(lián)合,充分發(fā)揮資源整合和產(chǎn)業(yè)協(xié)同優(yōu)勢(shì),依托濰柴CVT動(dòng)力總成技術(shù)和配套,成功開發(fā)出大馬力CVT無級(jí)變速拖拉機(jī),縮小了與國(guó)外的技術(shù)差距,推動(dòng)了行業(yè)的轉(zhuǎn)型升級(jí)。2021年青島農(nóng)機(jī)展上,濰柴雷沃發(fā)布了我國(guó)首款商業(yè)化CVT智能拖拉機(jī)——雷沃P7000大馬力智能拖拉機(jī),是國(guó)內(nèi)首款由自主研發(fā)、具有自主知識(shí)產(chǎn)權(quán)的智能CVT重型智能拖拉機(jī)。
 
  另悉,柳工集團(tuán)無級(jí)變速拖拉機(jī)仍處于研發(fā)階段。公司萬臺(tái)拖拉機(jī)整機(jī)生產(chǎn)線在2021年底已實(shí)現(xiàn)試運(yùn)行。
 
  國(guó)際上的拖拉機(jī),智能化、信息化技術(shù)水平不斷提高,各種高新技術(shù),如電子控制系統(tǒng)、自動(dòng)導(dǎo)航技術(shù)、無人駕駛技術(shù)、新型駕駛室技術(shù)、ABS及線控技術(shù)、虛擬現(xiàn)實(shí)技術(shù)和液壓技術(shù)等越來越多地應(yīng)用到拖拉機(jī)上。尤其是電子和信息技術(shù)的應(yīng)用,不僅使拖拉機(jī)的經(jīng)濟(jì)性得到提升,同時(shí)也改善了拖拉機(jī)的駕駛操縱舒適性和監(jiān)控性能。國(guó)內(nèi)的拖拉機(jī),個(gè)別企業(yè)也采用了自動(dòng)導(dǎo)航技術(shù)、無人駕駛技術(shù)、液壓控制技術(shù)等,但拖拉機(jī)行業(yè)總體水平還有待提高。
