Abstract
A multi-pump driven single-motor hydro-mechanical hybrid transmission device includes an input shaft, a planetary gear split mechanism, a hydraulic transmission system, a planetary gear convergence mechanism, and an output shaft. The input shaft is connected to the hydraulic transmission system and the planetary gear convergence mechanism through the planetary gear split mechanism. The hydraulic transmission system and the planetary gear convergence mechanism are both connected to the output shaft. The hydraulic transmission system includes a multi-pump driving mechanism, a fixed displacement motor mechanism, and a hydraulic transmission output mechanism. The multi-pump driving mechanism is connected to the fixed displacement motor mechanism. The fixed displacement motor mechanism is connected to the planetary gear convergence mechanism and is connected to the output shaft through the hydraulic transmission output mechanism.
