The pump wheel and the torque converter shell are connected into a whole and fixed on the flange of the input shaft by bolts, the inner side of the pump wheel is composed of a plurality of curved blades and is a driving part, so that oil in the blades can flow outwards along the curved surfaces under the action of centrifugal force, and the oil is emitted to the inlet of the turbine blade at the outlet of the blade to finish the conversion from mechanical energy to fluid kinetic energy; the turbine consists of a plurality of curved blades, is a driven part, is connected with the transmission system through an output shaft, and outputs torque through the output shaft so as to convert the kinetic energy of liquid into mechanical energy of the output shaft; the guide wheel is a fixed working wheel, is connected with the shell of the speed changer through a guide wheel fixing seat, is composed of a plurality of curved blades, and oil flowing out of the turbine flows into the pump wheel after changing the direction through the oil duct to bear a reaction moment.

The hydraulic torque converter of engineering machinery is mainly cast aluminum, wherein a pump wheel, a turbine and a guide wheel are collectively called as an aluminum wheel, and the production flow of the aluminum wheel is mainly subjected to the processes of lifting a die, sand discharging, die assembling, pouring, die opening, oxide skin cleaning, piece taking and the like, and the production and the manufacture of the hydraulic torque converter of engineering machinery are mainly carried out by adopting a traditional mode, namely manual casting. For example, patent document CN101963220B discloses a hydraulic torque converter and a method for manufacturing the same, in which a pump impeller and a turbine structure of the hydraulic torque converter are decomposed into an outer ring body and an inner ring body, the outer ring body and a blade of the outer ring body are manufactured by a pressure casting process, the inner ring body is manufactured by a pressure casting or punching process, the outer ring body and the inner ring body are brazed or riveted and connected into a whole by a brazing or riveting mode, a positioning column is cast on the blade when the outer ring body is subjected to pressure casting, a positioning hole is manufactured when the inner ring body is subjected to pressure casting or punching, and the outer ring body and the inner ring are subjected to positioning connection through the outer ring body positioning column and the inner ring positioning hole when the outer ring body and the inner ring are brazed or riveted. The traditional casting mode needs to be operated manually, the operation mode is backward, the labor intensity of workers is high, the production efficiency is low, and the productivity is greatly limited.
