Abstract: A hybrid transmission device with a mechanical continuously variable transmission and a control method thereof are provided. The device includes an input shaft assembly, a front planetary gear transmission assembly, a rear planetary gear transmission assembly, an output shaft, and a mechanical continuously variable transmission. Single transmission modes and hybrid transmission modes are implemented through combination and engagement/disengagement of brakes and clutches. The device and the method realize free switching among various transmission modes and integrates the single transmission modes and the hybrid transmission modes, thereby increasing the degree of freedom in adjustment and expanding the speed regulation range. Input and output shafts of a front cup wheel and ring disc transmission mechanism and a rear cup wheel and ring disc transmission mechanism are coaxial, so that the structure is compact and intermediate rollers can stably and reliably transmit large torque.

Abstract: A multi-mode hydro-mechanical hybrid transmission device includes an input member, a hydraulic transmission mechanism, a mechanical transmission mechanism, a convergence mechanism, an output member, a clutch assembly, and a brake assembly. The clutch assembly connects an output end of the input member to an input end of the hydraulic transmission mechanism, the mechanical transmission mechanism, and the convergence mechanism. The clutch assembly connects an output end of the hydraulic transmission mechanism to the convergence mechanism. The clutch assembly connects the mechanical transmission mechanism to the convergence mechanism. The convergence mechanism is connected to the output member. Continuously changing transmission ratios are provided between the input member and the output member by adjusting a displacement ratio of the hydraulic transmission mechanism and selectively controlling engagement of the clutch assembly and the brake assembly.

Abstract: A hydro-mechanical series and parallel transmission device and a control method thereof are provided. The device includes an input shaft assembly, a hydraulic transmission assembly, a planetary gear transmission assembly, an intermediate gear transmission assembly, and an output shaft assembly. Switching among a hydraulic transmission mode, a mechanical transmission mode, and a hydro-mechanical composite transmission mode is implemented through combination and engagement/disengagement of clutches and brakes. The hydro-mechanical series transmission is used to expand the speed regulation range of the hydraulic transmission and is combined with the hydraulic transmission to meet the requirements on precision and the speed regulation range. The requirements of low-power and high-power operations are met through combination of the hydro-mechanical series and parallel transmissions. Multiple transmission modes are formed to adapt to the working conditions of startup, operation, and transfer.
