Abstract Based on one-dimensional flow theory，a model of tractor-brake hydraulic torque converter was established． A structure w as designed based on an old hydraulic torque converter D430． Its original characteristic was got through calculation． Original characteristic com pareanalysis to hydraulic torque converter D430 was made which proved that the results are reasonable and are im portant to design tractor-brake hydraulic torque convertor．
