Application Field Of Hydraulic Couple
Jun 29, 2017


The hydraulic coupler was used in the early semi-automatic transmission and automatic transmission of automobiles. The pump wheel of the hydraulic coupler is connected with the flywheel of the engine, and the power is introduced by the crankshaft. In some cases, the coupler is strictly a part of the flywheel, in which case the hydraulic coupler is called a hydrodynamic flywheel. The turbine is connected to the input shaft of the transmission. The fluid circulates between the pump wheel and the turbine, allowing the torque to pass from the engine to the transmission and drive the vehicle forward. In this respect, the hydrodynamic coupler acts very much like a mechanical clutch in a manual transmission. Due to the inability of the hydraulic coupler to change the size of the torque, it has been replaced by a hydraulic torque converter.


It can be used in metallurgical equipment, mining machinery, power equipment, chemical industry and various engineering machinery.
