A set of hydraulic driving device is designed for the mine monorail. The three-dimensional model of the driving mechanism is established by the Solidworks modeling software. The stress state of the driving wheel is analyzed,the hydraulic driving circuit is designed and the driving principle is expounded. The simplified hydraulic driving circuit is established by the hydraulic simulation software AMESim and the main parameters are set according to the actual working conditions. The displacement curve of mass block of the one-way throttle valve model, the change curve of motor speed and output torque and the change curve of oil pressure in the pump are obtained. The results show that for the monorail car that the driving force is 20 k N,the response time of the loop is 0.7 s,the motor′s steady running speed is 82 r/min,the output torque and the oil pressure in the pump meet the basic requirements of the operation of the monorail locomotive.
