Title:
MULTI-MODE MECHANICAL-HYDRAULIC COMPOSITE TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/159408
Kind Code:
A1
Abstract:
The present invention provides a multi-mode mechanical-hydraulic composite transmission device, comprising an input component, a hydraulic transmission mechanism, a mechanical transmission mechanism, a confluence mechanism, an output component, a clutch assembly, and a brake assembly. The clutch assembly connects an output end of the input member respectively to an input end of the hydraulic transmission mechanism, the mechanical transmission mechanism and the confluence mechanism, the clutch assembly connects an output end of the hydraulic transmission mechanism to the confluence mechanism, and the clutch assembly connects the mechanical transmission mechanism to the confluence mechanism. The confluence mechanism is connected to the output component. A continuously variable transmission ratio between the input component and the output component is provided by adjusting a displacement ratio of the hydraulic transmission mechanism and selectively controlling the engagement between the clutch assembly and the brake assembly. According to the present invention, switching of modes such as mechanical transmission, hydraulic transmission and mechanical-hydraulic composite transmission can be implemented, thereby increasing the adjustment degree of freedom while the fault-tolerant performance of a system is improved, and expanding the speed regulation range in advancing and retreating directions.
