How the torque converter works
The torque converter has three working wheels, namely the pump wheel, the turbine and the guide wheel. The structure of the pump wheel and the turbine is basically the same as that of the hydraulic coupler; the guide wheel is located between the pump wheel and the turbine, and maintains a certain axial clearance with the pump wheel and the turbine, and is fixed to the transmission housing through the guide wheel fixing sleeve. When the engine is running, the housing of the hydraulic torque converter and the pump wheel rotate together, and the hydraulic oil in the pump wheel is rushed toward the turbine by the outer edge of the pump wheel blade under the action of centrifugal force. And flowing along the turbine blade guide wheel, and then flowing back to the inner edge of the pump wheel blade through the guide vane blade to form a circulating liquid flow. The role of the guide wheel is to change the output torque on the turbine. Since the hydraulic oil flowing from the lower edge of the turbine blade still has a considerable impact force, as long as the blades of the pump wheel, the turbine and the guide wheel are designed to have a certain shape and angle, the above impact force can be utilized to increase the output of the turbine.
