    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.

    Abstract: A hydro-mechanical hybrid transmission device with an energy management mechanism includes an input member, a mechanical transmission mechanism, an energy management mechanism, a power output mechanism, an output member, a convergence mechanism, a start mechanism, a hydraulic transmission mechanism, a clutch assembly, and a brake assembly. The clutch assembly connects the input member to the mechanical transmission mechanism, the power output mechanism, and the hydraulic transmission mechanism, and connects the energy management mechanism to the mechanical transmission mechanism and the power output mechanism. The clutch assembly and the brake assembly provide a continuous transmission ratio between the input member and the output member and/or the power output mechanism, between the energy management mechanism and the output member and/or the power output mechanism, and between the energy management mechanism together with the input member and the output member and/or the power output mechanism.

    Abstract: A hydro-mechanical transmission device with a dual-clutch transmission includes an input mechanism, a pump-controlled motor mechanism, an odd-numbered gear transmission mechanism, an even-numbered gear transmission mechanism, an output mechanism, and a jackshaft. The input mechanism is connected to the odd-numbered gear transmission mechanism and the even-numbered gear transmission mechanism that are connected in parallel, and is connected to an input end of the pump-controlled motor mechanism. An output end of the pump-controlled motor mechanism is connected, through the jackshaft, to the odd-numbered gear transmission mechanism and the even-numbered gear transmission mechanism that are connected in parallel, and is connected to the output mechanism. Switching among hydraulic transmission, hydro-mechanical transmission, and mechanical transmission modes between the input mechanism and the output mechanism is implemented by controlling combination and engagement/disengagement of clutches and a brake.
