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.
