拖拉机不仅是田间作业动力 ,也是我国重要的农村运输工具。长期以来拖拉机运输性能的检测缺乏合适的检测设备。文中介绍了一种 YTC型移动式拖拉机性能检测线。该设备移动方便 ,操作简单。制动力矩精度达 0 .98N· m,轴重精度达 0 .1kg,车速精度达 0 .0 1km / h,每 3m in内完成一台车检测 ,一天可连续检测 15 0台。实际应用表明 ,该新型检测线可作为农机管理部门开展拖拉机年检年审工作的检测设备 Tractor is not only the field work motivation, but also China’s important rural transport. For a long time tractor transport performance testing lack of suitable testing equipment. This paper introduces a YTC mobile tractor performance testing line. The device is easy to move and easy to operate. Braking torque accuracy of 0.98N · m, shaft accuracy of 0 .1kg, speed accuracy of 0. 01km / h, every 3m in to complete a car test, a day can be continuously testing 150 sets. Practical application shows that the new testing line can be used as agricultural machinery management departments to conduct annual inspection of tractors annual inspection equipment
