導讀:在我國,動力換擋、無級變速技術(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)機網(wǎng) 編輯視角】百余年來,隨著工業(yè)制造能力和科學技術(shù)的不斷發(fā)展,
拖拉機技術(shù)已經(jīng)發(fā)生了翻天覆地的變化。變速箱作為拖拉機的主要部件之一,其技術(shù)已經(jīng)從最初的滑動齒輪換擋、嚙合套換擋、同步器換擋到如今廣泛應(yīng)用的動力換擋和無級變速。
對于像約翰迪爾、凱斯、愛科這些世界級農(nóng)機巨頭來說,動力換擋該技術(shù)已經(jīng)在其拖拉機上運用得相當成熟和廣泛。在我國,動力換擋、無級變速技術(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,大部分拖拉機還是采用機械換擋。近年來,我國農(nóng)機企業(yè)也不甘示弱,力爭迎頭趕上。
魯中拖拉機——近日,濰坊魯中拖拉機有限公司憑借功率合流無級變速拖拉機的研發(fā),成功入選2022年山東省首臺套技術(shù)裝備。據(jù)了解,該無級變速拖拉機采用了液壓機械功率合流傳動技術(shù),具有較高的傳動效率,更易于實現(xiàn)無人駕駛和智能操作。但首臺套的新裝備想要贏得市場的青睞,還要闖過用戶不信任、生產(chǎn)成本高、國際同行擠壓等多個難關(guān)。
中聯(lián)重科——2022年8月8日,中聯(lián)重科宣布其PV1104動力換向水田拖拉機在湖南常德正式下線,P系列動力換擋拖拉機家族再添新成員。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)的動力換向變速箱,換向操作簡單高效。
玉柴集團——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,玉柴芯藍非道路用拖拉機IE-Power動力總成是眾人關(guān)注的焦點之一。它是中國首款拖拉機電驅(qū)無級變速動力總成,是由玉柴完全自主研發(fā)的拖拉機用串聯(lián)式混合動力總成技術(shù)解決方案,一款拖拉機電驅(qū)無級變速動力總成,由
發(fā)動機、
發(fā)電機、驅(qū)動電機、電動換檔變速箱組成,適配200~260馬力拖拉機。玉柴拖拉機IE-Power打破了國外CVT技術(shù)壟斷,填補了國內(nèi)技術(shù)空白。它以最簡單高效的方式實現(xiàn)拖拉機無級變速功能。它采用高度技術(shù)集成設(shè)計,關(guān)鍵部件模塊化,實現(xiàn)了拖拉機底盤升級。
【詳情】 中國一拖——東方紅 LW2304輪式拖拉機是2021年青島國際農(nóng)機展首次亮相的東方紅新品大馬力拖拉機,它是中國一拖為國內(nèi)大型農(nóng)場及替代進口需要而開發(fā)的具有完全自主知識產(chǎn)權(quán)的新一代無級變速重型輪式拖拉機。該產(chǎn)品為旱地農(nóng)業(yè)一般用途,特別適用于大型農(nóng)場的耕、耙、復式作業(yè)等重負荷作業(yè),可實現(xiàn)與其它農(nóng)機的聯(lián)合精準作業(yè)。
【詳情】 濰柴雷沃——濰柴雷沃是濰柴集團和雷沃重工戰(zhàn)略重組的“產(chǎn)品”。兩家企業(yè)強強聯(lián)合,充分發(fā)揮資源整合和產(chǎn)業(yè)協(xié)同優(yōu)勢,依托濰柴CVT動力總成技術(shù)和配套,成功開發(fā)出大馬力CVT無級變速拖拉機,縮小了與國外的技術(shù)差距,推動了行業(yè)的轉(zhuǎn)型升級。2021年青島農(nóng)機展上,濰柴雷沃發(fā)布了我國首款商業(yè)化CVT智能拖拉機——雷沃P7000大馬力智能拖拉機,是國內(nèi)首款由自主研發(fā)、具有自主知識產(chǎn)權(quán)的智能CVT重型智能拖拉機。
另悉,柳工集團無級變速拖拉機仍處于研發(fā)階段。公司萬臺拖拉機整機生產(chǎn)線在2021年底已實現(xiàn)試運行。
國際上的拖拉機,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)、自動導航技術(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)實技術(shù)和液壓技術(shù)等越來越多地應(yīng)用到拖拉機上。尤其是電子和信息技術(shù)的應(yīng)用,不僅使拖拉機的經(jīng)濟性得到提升,同時也改善了拖拉機的駕駛操縱舒適性和監(jiān)控性能。國內(nèi)的拖拉機,個別企業(yè)也采用了自動導航技術(shù)、無人駕駛技術(shù)、液壓控制技術(shù)等,但拖拉機行業(yè)總體水平還有待提高。
