| 摘 要： | 提出了双轮驱动电动拖拉机的总体结构方案,从作业受力和牵引效率2个方面分析了电动拖拉机的牵引性能,并进行了传动部件的匹配分析。在此基础上搭建了电动拖拉机传动试验平台,分别进行了牵引性能、带载启动及运输工况等试验。试验结果表明,所设计的电动拖拉机牵引转矩达到1 800 N·m,可满足更大耕深作业。带载启动时,驱动转矩从700 N·m增至1 600 N·m,车速由0增至7 km/h,所用时间约为1.1 s。运输试验运输货物为1 710 kg时,速度达到6.5 km/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. |
