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.

The device includes an input shaft assembly, a power-split assembly, a hydraulic transmission assembly, an electrical variable transmission assembly, a mechanical transmission assembly, a power-convergence assembly, and an output shaft. Three types of transmission modes including single transmission modes, power-split composite transmission modes, and power-convergence composite transmission modes are implemented by controlling engagement and disengagement of clutches and a brake. The present disclosure has the following beneficial effects: Free switching between various transmission modes is realized, the requirements of engineering machinery for a transmission device with multiple modes in different working conditions are satisfied, the engine power utilization is improved, and the fuel economy is increased. The shift impact is effectively reduced and the speed ratio adjustment range is expanded. The hydraulic transmission enables quick startup and stable operation and implements speed variation and direction change easily and rapidly without causing impact. The electrical variable transmission has a continuously changing transmission ratio and causes extremely small impact on the mechanism during operation.
