　　【農(nóng)機網(wǎng) 明星企業(yè)】在8月8日舉行的中國農(nóng)業(yè)機械學(xué)會科技成果評價會上，中聯(lián)重科“設(shè)施園藝新能源純電動拖拉機”項目獲得專家組高度評價，被認(rèn)定為達(dá)到國際先進(jìn)水平的科技成果。
 
▲中聯(lián)重科CA504ET純電動拖拉機
 
　　本次會議由中國農(nóng)業(yè)機械學(xué)會秘書長趙鳳敏主持。中國農(nóng)業(yè)機械化科學(xué)研究院集團(tuán)有限公司總工程師方憲法擔(dān)任專家組組長，來自農(nóng)機、農(nóng)藝、三電(電池、電機、電控)領(lǐng)域的七名資深專家組成專家組。中聯(lián)農(nóng)機聯(lián)席總經(jīng)理郭崗出席會議并參加匯報。秉承科學(xué)、客觀、公平的原則，專家組認(rèn)真聽取了中聯(lián)重科項目組的匯報，審查了提交的技術(shù)文件和視頻。經(jīng)過質(zhì)詢、答疑和討論環(huán)節(jié)，專家組一致認(rèn)為該項目所開發(fā)的動力總成電動化技術(shù)、電機與拖拉機底盤適配性技術(shù)以及整車行走與作業(yè)動力輸出獨立驅(qū)動架構(gòu)，在保證功能、性能的基礎(chǔ)上，有效壓縮了傳動系統(tǒng)尺寸和重量，提高了電機高效運行區(qū)占比和整車能量利用效率，延長了續(xù)航作業(yè)時間，并使行走與作業(yè)雙電機完全解耦，實現(xiàn)了車速和PTO一鍵式獨立無級變速操控，提高了拖拉機作業(yè)適應(yīng)性。在新能源技術(shù)應(yīng)用、設(shè)施園藝場景應(yīng)用等方面優(yōu)于國際同類對標(biāo)產(chǎn)品，達(dá)到國際先進(jìn)水平。
 
▲CA504ET純電動拖拉機進(jìn)入成熟應(yīng)用階段
 
　　“設(shè)施園藝新能源純電動拖拉機”項目定位于解決我國農(nóng)機裝備電動化短板問題，由中聯(lián)重科聚集頂尖研發(fā)資源，圍繞新能源電驅(qū)應(yīng)用與智能套件開發(fā)、動力總成電動化、行走與作業(yè)系統(tǒng)獨立驅(qū)動、減速器分動器一體化設(shè)計等科研難點進(jìn)行集中攻關(guān)，已布局相關(guān)核心專利近20件，是推動我國農(nóng)機裝備向“綠色化、智能化、數(shù)字化”轉(zhuǎn)型升級的代表性科技成果。
 
▲CA504ET純電動拖拉機可實現(xiàn)快充補能
 
▲CA504ET純電動拖拉機配備雙電機系統(tǒng)
 
▲CA504ET純電動拖拉機具備無人駕駛功能
 
　　目前，由該科技成果孵化出的CA504ET純電動拖拉機已進(jìn)入成熟應(yīng)用階段。該產(chǎn)品采用鋰電池作為能量源，行駛、作業(yè)無污染零排放。電池續(xù)航時間長，可實現(xiàn)1小時快充補能(電量從15%—90%)；配置“行走電機和作業(yè)電機”的雙電機系統(tǒng)，四輪驅(qū)動，液壓轉(zhuǎn)向，可實現(xiàn)行走與作業(yè)的無級變速與自動換向，具備定速巡航、液壓懸掛位控制功能，并可配備無人駕駛、AI智能作業(yè)等智能模塊，是國內(nèi)首款實用型新能源純電動拖拉機，打破了國外產(chǎn)品在該領(lǐng)域的技術(shù)壟斷。
