Title:
MECHANICAL-ELECTRIC-HYDRAULIC COMPOSITE DRIVE DEVICE, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/236127
Kind Code:
A1
Abstract:
Disclosed in the present invention are a mechanical-electric-hydraulic composite drive device, and a control method therefor. The device comprises an input shaft assembly, a power-dividing assembly, a hydraulic drive assembly, an electrical continuously variable transmission drive assembly, a mechanical drive assembly, a power-combination assembly, and an output shaft. Three types of drive modes, i.e., a single-type drive mode, a power-dividing composite drive mode, and a power-combination composite drive mode can be achieved by means of controlling the switching of engagement between a clutch and a brake. The beneficial effects of the device lie in that free switching between various drive modes can be achieved, which can meet the multi-mode requirements of engineering machinery for a drive device under different working conditions, increase the engine power utilization, and improve the fuel economy; the impact of shifting is effectively reduced, and the speed ratio adjustment range is expanded; and the hydraulic drive starts quickly, operates smoothly, and it is easy to achieve rapid and impact-free speed change and reversing, and the electrical continuously variable transmission has a continuous drive ratio change process, and thus has little impact on the mechanism during use.
