Single-grade centripetal turbine hydraulic torque converter with prepositioned force taking opening

The utility model relates to a single-grade centripetal turbine hydraulic torque converter with a prepositioned force taking opening. The single-grade centripetal turbine hydraulic torque converter comprises a shell and a cover wheel, wherein a cover shell is arranged on one side face of the shell; spaces in the cover shell and the shell are separated by a main separation board and a secondary separation board; a guide wheel seat is fixedly arranged at the other side of the shell; the guide wheel seat is internally provided with a turbine shaft in a rolling manner; the cover wheel is mounted at one end of the turbine shaft in the rolling manner; the cover wheel and a pump wheel are peripherally fixed; the pump wheel and a pump hub are peripherally fixed; the pump hub and a driving gear are peripherally fixed; the guide wheel seat is peripherally and rotatably sleeved with the pump hub; a guide wheel is further peripherally and fixedly arranged at one end, which is far away from the shell, on the guide wheel seat; the turbine shaft is further provided with a turbine by a turbine hub; the turbine is located in a space formed by the cover wheel and the pump wheel; a stretching-out end of the turbine shaft is further axially and fixedly provided with an output flange; the shell is internally provided with a force taking opening driving shaft in the rolling manner; a driven gear is peripherally and fixedly arranged on the force taking opening driving shaft; a force taking opening output flange is peripherally and fixedly arranged at one end of the force taking opening driving shaft; the driven gear is engaged with the driving gear. The single-grade centripetal turbine hydraulic torque converter has the advantages that the power loss is low and the transmission efficiency is high.
