Test device for high-torque hydraulic motor travel motor

The utility model provides a test device for a high-torque hydraulic travel motor. The test device comprises a base, a reducer, a torque meter, a loading pump and a loading pump mounting frame, wherein the loading pump mounting frame is fixed on the base; the pump body of the loading pump is fixed on the loading pump mounting frame; the input shaft of the reducer is connected with the output shaft of a tested hydraulic motor; a moving part of the loading pump is connected with the output shaft of the reducer; and the torque meter is mounted on the output shaft of the reducer. In the test process, the tested hydraulic motor rotates in one direction under drive of hydraulic oil, the loading pump hydraulically exerts an opposite torque for twisting, and the torque value is measured by the torque meter. The test device for the high-torque hydraulic travel motor not only solves the problem that the high-torque hydraulic travel motor has an extremely small test torque, and improves the test torque measurement range
