Abstract: A gear-hydraulic-metal belt integrated multi-mode hydro-mechanical hybrid transmission device includes an input assembly, an output assembly, a metal belt transmission mechanism, a planetary gear assembly, a hydraulic transmission mechanism, a clutch assembly and a brake assembly. The input assembly is connected to the metal belt transmission mechanism, the planetary gear assembly and the hydraulic transmission mechanism. The metal belt transmission mechanism and the hydraulic transmission mechanism are connected to the planetary gear assembly. The planetary gear assembly is connected to the output assembly. The clutch assembly connects the input assembly to the metal belt transmission mechanism and the planetary gear assembly, and connects each of the metal belt transmission mechanism and the hydraulic transmission mechanism to the planetary gear assembly. The clutch assembly and the brake assembly provide a continuous transmission ratio between the input assembly and the output assembly.

Abstract: A hydro-mechanical hybrid transmission device and a control method thereof are provided. The device includes an input shaft, a split mechanism, a mechanical transmission assembly, a hydraulic transmission assembly, and an output shaft, wherein the input shaft is connected, through the split mechanism, to the mechanical transmission assembly and the hydraulic transmission assembly that are connected in parallel, and the mechanical transmission assembly and the hydraulic transmission assembly are both connected to the output shaft. The mechanical transmission assembly includes a front planetary-gear-set assembly and a rear planetary-gear-set assembly. The front planetary-gear-set assembly and the rear planetary-gear-set assembly are connected in series. The control method includes three modes of transmission: pure hydraulic transmission, hydro-mechanical hybrid transmission, and pure mechanical transmission are implemented through combination and engagement/disengagement of gear-shift components.
