Title:
MECHANICAL-DOUBLE-RING-HYDRAULIC COMPOSITE TRANSMISSION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2023/159534
Kind Code:
A1
Abstract:
A mechanical-double-ring-hydraulic composite transmission mechanism, comprising an input member, a converging mechanism, a hydraulic transmission mechanism, a double-ring mechanism, an output member, a clutch assembly, and a brake assembly. The clutch assembly connects a left planetary gear train to a right planetary gear train; connects the input component to the hydraulic transmission mechanism, the double-ring mechanism, the left planetary gear train, and the right planetary gear train, respectively; connects the hydraulic transmission mechanism to the right planetary gear train; connects the double-ring mechanism to the left planetary gear train; and connects the left planetary gear train and the right planetary gear train respectively to the output member. By adjusting the displacement ratio of the hydraulic transmission mechanism and the transmission ratio of the double-ring transmission mechanism, and selectively controlling the connection of the clutch assembly and the brake assembly, a continuous transmission ratio between the input member and the output member is provided, thereby implementing free switching between various transmission modes.
