Changfa Group, Changzhou 213000, China )AbstractAccording to the testing requirements of tractor power shift transm ission, a power shift transm issiontestbed for large-scale tractor was designed. The power shift transm ission
3、, drive motor, loading motorand energy feedback system were designed. The electronic control unit and electronic measurementsystem were developed. The overall scheme of tests for power shift transm ission was determ ined andtested. The test results showed that the power of proposed test bed was up t
4、o 250 kW. A closed-loopfeedback of energy was achieved thus energy-saving rate in overload operating conditions reached to80%. The inputspeed and torque, output speed and torque, hydraulic system flow and pressure could betested w ith the system. The testbed was operated steadily and couldmeet the d
