    摘要:

    提出了雙輪驅(qū)動電動拖拉機的總體結(jié)構(gòu)方案,,從作業(yè)受力和牽引效率2個方面分析了電動拖拉機的牽引性能,并進行了傳動部件的匹配分析,。在此基礎(chǔ)上搭建了電動拖拉機傳動試驗平臺,,分別進行了牽引性能,、帶載啟動及運輸工況等試驗,。試驗結(jié)果表明,,所設(shè)計的電動拖拉機牽引轉(zhuǎn)矩達到1800N·m,,可滿足更大耕深作業(yè)。帶載啟動時,,驅(qū)動轉(zhuǎn)矩從700N·m增至 1600N·m,,車速由0增至7km/h,所用時間約為1.1s,。運輸試驗運輸貨物為1710kg時,,速度達到6.5km/h。

    Abstract:

    Two-wheel drive electric tractor has several advantages, including simple structure and electrically differential and flexible manipulation in narrowly closed working environment, and it enables us to make full use of adhesion and improve adhesion utilization and dynamic performance. The overall structure program of two-wheel drive electric tractor was proposed which adopted two 5kW drive motors. Electric drag traction performance was analyzed from both electric tractor load stress and traction efficiency aspects. Matching analysis of transmission components was also put forward based on force balance equation of electric tractor cultivation operation. Tests on traction performance, load startup and transportation conditions were done in the built electric tractor driving test platform. According to the result, the proposed electric tractor torque reached 1800N·m, which can meet the need of deeper tillage operations. With load started, driving torque value was increased from 700N·m to 1600N·m and speed was increased from 0 to 7km/h, which spent about 1.1s. As for transport experiments, when transported goods were weighed 1710kg, the speed reached 6.5km/h.
