Framework test bed for testing train wheel set

The utility model relates to the technical field of test benches. The utility model relates to a test bench, in particular to a framework test bench for train wheelset experiments. The test bench comprises a test bench body, conveyor belts are symmetrically arranged on the left and right sides above the test bench body. Rolling wheels are arranged at the two ends in the conveying belt. A motor isarranged on one side of the rolling wheel; an output shaft of the motor is fixedly connected with the rolling wheel through a coupler; the other end of the rolling wheel is rotationally connected witha fixed rod through a bearing; two sides of a rolling wheel at the other end of the conveyor belt are rotationally connected to the top ends of fixed rods through bearings; the outer wall of each conveying belt is sleeved with a rubber rail, the two rubber rails are fixedly connected to the outer walls of the conveying belts through bolts, a sleeper support is arranged between the rubber rails, train wheels are fixed thro
