The invention relates to an efficient four-degree-of-freedom comprehensive transmission device which comprises a hydraulic torque converter, a planetary speed change mechanism, a fan hydro-viscous speed regulation component, a gear shifting hydraulic control component, a hydraulic stepless steering component and a hydraulic-mechanical combined braking component. On the basis of four planet rows, the functions of seven forward gears, one central steering gear and three reverse gears and efficient power transmission of the transmission device are achieved by reasonably controlling combination or separation of gear shifting control components. According to hydraulic stepless steering, a variable pump and a constant displacement motor with back-to-back space structures serve as core components, and zero-differential stepless steering can be achieved. The fan speed regulating device takes a hydro-viscous clutch as a core component to realize stepless regulation of the rotating speed of the fan. According to the hydraulic-mechanical combined braking device, the hydraulic retarder and the mechanical brake form a constant-torque combined braking system, and the continuous and frequent braking performance of a vehicle can be greatly improved.
