Problems solved by technology

At present, the design idea of ​​mechanical-hydraulic transmission is to sacrifice the transmission efficiency and speed regulation range of the secondary working area in exchange for the high-efficiency transmission of the main working area. The traditional design idea is difficult to take into account various working conditions including direction change and mode switching. Transmission needs
[0004] When the traditional transmission device realizes forward transmission and reverse transmission, the structure of power splitting and power converging is single, and it is difficult to take into account each other, which is not conducive to optimizing the structural parameters, and it is easy to generate circulating power, which reduces the transmission efficiency
Transmission devices with multiple modes often have fewer gears to choose from within the mode, which cannot adapt to the operation requirements of complex working conditions

Abstract

The invention discloses a mechanical hydraulic compound transmission device and a control method. The mechanical hydraulic compound transmission device comprises an input shaft, a shunt mechanism, a hydraulic transmission assembly, a mechanical transmission assembly, a power dividing mechanism and an output shaft. The input shaft is connected with the hydraulic transmission assembly and the mechanical transmission assembly through the power dividing mechanism, and the hydraulic transmission assembly and the mechanical transmission assembly are connected in parallel. The hydraulic transmissionassembly and the mechanical transmission assembly are connected with the output shaft through the power dividing mechanism. The mechanical hydraulic compound transmission device has the beneficial effects that through combination of switching between a planetary gear structure and a brake and switching between the planetary gear structure and a clutch, the structural forms of power dividing and power gathering are realized; when forward transmission and reverse transmission are realized, the structural forms of power dividing and power gathering are diversified and compatible, and structure parameters can be optimized; moreover, occurrence of power circulation is avoided, and the transmission efficiency is improved. The transmission device has multiple optional gear levels and can adapt tooperation requirements under complex conditions. Moreover, a one-way variable pump and a one-way constant displacement motor are adopted, and the production and maintenance cost is greatly reduced.
