A main body structure of a hydrodynamic coupler with centrifugal diversion and intelligent speed adjustment belongs to the technical field of energy-saving and hydrodynamic transmission. The structure comprises a pump wheel, a pump wheel flange, a turbine, a driving shaft, a driven shaft, a case body, oil inlet/outlet connecting tubes, a rotation speed sensor, a speed-measuring gear, a rotating shell, a rotating shell flange, nozzles, left and right sealed end surfaces and an oil seal ring. Based on the principle of centrifugal diversion, the working oil is led out of the nozzles arranged on the rotating shell and cooled under the centrifugal action, and the quantity and aperture of the nozzles are determined by the type and the load characteristics of the coupler, so as to improve the load adaptability of the coupler. The labyrinth oil seal in axial arrangement can greatly reduce the leakage at the seals, and help the coupler reduce energy loss and improve the controllability of rotation speed and stability of operation. The coupler is externally supported to prevent the case body from bearing the self-weight of the coupler and the case body is only used for storing oil. The invention also has the advantages of small wall thickness and size, compact overall structure, reduced material consumption and good social and economic benefits.
