Axle muddy water test bed

The invention relates to an axle muddy water test bench, which comprises a motor supporting seat, a motor, a dynamic torque sensor, a muddy water tank, a clamp and a control system, and is characterized in that the motor is arranged on the motor supporting seat, the dynamic torque sensor is connected with the motor, the clamp is arranged in the muddy water tank, and a test piece is arranged on the clamp and is connected with the motor; the motor and the dynamic torque sensor are respectively connected with the control system; during testing, muddy water slurry is placed in the muddy water tank, a test piece is arranged in the muddy water tank through the clamp and soaked in the muddy water slurry, the test piece is driven through rotation of the motor and tested, and torque information is collected through the dynamic torque sensor. By detecting whether the wading performance of the wading parts of the axle assembly meets the design requirement or not, the performance of the axle can be better known, and the
