導(dǎo)讀：中國一拖十年磨一劍，成功研制出東方紅LW3204無級變速拖拉機(jī)，整體技術(shù)達(dá)到國際先進(jìn)水平，打破了國外技術(shù)壟斷，為保障國家糧食安全提供了重要支撐。

　　LW3204
 
　　大馬力無級變速拖拉機(jī)研發(fā)創(chuàng)新路
 
　　我國是農(nóng)業(yè)大國，有著數(shù)千年的農(nóng)耕文明歷史。實(shí)現(xiàn)從農(nóng)業(yè)大國到農(nóng)業(yè)強(qiáng)國的轉(zhuǎn)變，是中國農(nóng)業(yè)發(fā)展的理想傳承，也是筑牢糧食安全的“壓艙石”。加快建設(shè)農(nóng)業(yè)強(qiáng)國離不開發(fā)展高端農(nóng)機(jī)裝備。
 
　　為此，中國一拖十年磨一劍，成功研制出東方紅LW3204無級變速拖拉機(jī)，整體技術(shù)達(dá)到國際先進(jìn)水平，打破了國外技術(shù)壟斷，為保障國家糧食安全提供了重要支撐。
 
　　研制東方紅LW3204
 
　　無級變速拖拉機(jī)有何意義？
 
　　我國是傳統(tǒng)農(nóng)業(yè)大國，歷來重視農(nóng)業(yè)生產(chǎn)。2004年開始，國家陸續(xù)出臺鼓勵(lì)農(nóng)村土地流轉(zhuǎn)的政策，我國農(nóng)業(yè)進(jìn)入又一個(gè)“黃金十年”，百畝、千畝規(guī)模的土地合作社開始大量涌現(xiàn)。然而批量應(yīng)用在農(nóng)田上的大馬力拖拉機(jī)鮮有國產(chǎn)拖拉機(jī)身影。
 
　　為了振興國產(chǎn)拖拉機(jī)品牌，同時(shí)為國內(nèi)市場提供更高性價(jià)比的產(chǎn)品，2011年，中國一拖下決心瞄準(zhǔn)大馬力無級變速拖拉機(jī)進(jìn)行大力攻關(guān)。
 
　　然而，當(dāng)時(shí)國內(nèi)拖拉機(jī)領(lǐng)域還普遍采用機(jī)械傳動(dòng)技術(shù)，大馬力和無級變速技術(shù)都是新課題。
 
　　業(yè)內(nèi)專家認(rèn)為，大馬力無級變速拖拉機(jī)涉及的CVT技術(shù)是一項(xiàng)系統(tǒng)工程，技術(shù)門檻高，國內(nèi)毫無經(jīng)驗(yàn)可循；加之國外在大馬力CVT拖拉機(jī)技術(shù)及核心零部件上長期壟斷，國內(nèi)無論誰來研制大馬力無級變速拖拉機(jī)，幾乎都被認(rèn)為是天方夜譚。
 
　　如何啃下大馬力CVT拖拉機(jī)技術(shù)
 
　　這塊“硬骨頭”？
 
　　為了讓我國農(nóng)民能夠早日用上國產(chǎn)大馬力無級變速拖拉機(jī)，中國一拖拿出“不怕困難，勇于創(chuàng)新”的精神，在“兩眼一抹黑”的情況下，在一張白紙上從零開始攻關(guān)。
 
　　從2011年收購法國McCormick工廠，到2014年與采埃孚合資成立車橋公司；從建成我國最先進(jìn)的大輪拖、重柴生產(chǎn)基地，到率先研制和開發(fā)出動(dòng)力換擋拖拉機(jī)、電控柴油機(jī)、HM-CVT等，中國一拖攻堅(jiān)克難，為順利叩開大馬力無級變速拖拉機(jī)創(chuàng)新大門創(chuàng)造契機(jī)。
 
▲項(xiàng)目主創(chuàng)人員在研討
 
　　時(shí)間一點(diǎn)點(diǎn)過去，一個(gè)個(gè)疑難問題得到解決，研發(fā)工作一步步向前推進(jìn)。
 
　　最終歷時(shí)十年，中國一拖成功研制出國內(nèi)首臺自主可控的無級變速重型拖拉機(jī)，順利通過鑒定。被認(rèn)定項(xiàng)目創(chuàng)新性強(qiáng)，具有自主知識產(chǎn)權(quán)，形成了相應(yīng)的技術(shù)標(biāo)準(zhǔn)，整體技術(shù)達(dá)到國際先進(jìn)水平，可替代進(jìn)口需要，為推動(dòng)我國拖拉機(jī)技術(shù)升級換代進(jìn)程掀開了嶄新的一頁。
 
　　LW3204無級變速拖拉機(jī)的優(yōu)勢
 
　　是什么？
 
　　可以說LW3204無級變速拖拉機(jī)的誕生，引領(lǐng)了市場潮流。這款拖拉機(jī)采用國際主流的機(jī)械液壓雙功率流傳動(dòng)技術(shù)，實(shí)現(xiàn)了實(shí)用性和先進(jìn)性兼顧原則，在北大荒集團(tuán)友誼農(nóng)場驗(yàn)證期間得到普遍好評。
 
LW3204無級變速拖拉機(jī)高效省油，經(jīng)濟(jì)性好，作業(yè)可達(dá)到3萬畝。無級變速傳動(dòng)系統(tǒng)動(dòng)力傳遞平穩(wěn)，自動(dòng)模式可實(shí)現(xiàn)車速巡航，操作更方便精確、作業(yè)效率更高，豪華舒適型駕駛室的安全性能、減震性能、噪聲、視野均滿足歐洲E-mark認(rèn)證標(biāo)準(zhǔn)要求，可選裝的自動(dòng)轉(zhuǎn)向系統(tǒng)能夠輕松實(shí)現(xiàn)精準(zhǔn)作業(yè)……
 
　　目前，中國一拖對LW3204無級變速拖拉機(jī)進(jìn)行了大量優(yōu)化，重點(diǎn)圍繞控制系統(tǒng)優(yōu)化迭代、產(chǎn)品質(zhì)量過程控制和產(chǎn)品一致性上下功夫，產(chǎn)品的裝配維修方便性和可靠性得到進(jìn)一步提升，將成為國產(chǎn)拖拉機(jī)突破高端技術(shù)瓶頸的“破冰”之舉。
 
　　東方紅LW3204無級變速拖拉機(jī)的成功面世不僅填補(bǔ)了我國300馬力以上CVT拖拉機(jī)的市場空白，化解我國農(nóng)機(jī)行業(yè)“鎖喉之痛”；而且實(shí)現(xiàn)了對我國農(nóng)機(jī)裝備制造業(yè)核心技術(shù)創(chuàng)新與突破的引領(lǐng)，讓我國農(nóng)機(jī)裝備制造業(yè)實(shí)現(xiàn)與世界同步。
