GEAR-DUAL-RING-HYDRAULIC COMPOSITE TRANSMISSION DEVICE

WIPO Patent Application WO/2022/027723

A1

The present invention provides a gear-dual-ring-hydraulic composite transmission device, comprising an input mechanism, a dual-ring series transmission mechanism, a hydraulic transmission mechanism, an output member, a front planetary gear mechanism, a middle planetary gear mechanism, a rear planetary gear mechanism, a clutch assembly and a brake assembly. The output of the dual-ring series transmission mechanism is connected to the middle planetary gear mechanism; the clutch assembly makes the input mechanism respectively connect to the dual-ring series transmission mechanism, the hydraulic transmission mechanism and the front planetary gear mechanism; the output of the hydraulic transmission mechanism is connected to the middle planetary gear mechanism; the output of the rear planetary gear mechanism is connected to the output member; and the clutch assembly and the brake assembly provide a continuous transmission ratio between the input mechanism and the output member. In the present invention, single-flow transmission, dual-ring single-flow transmission, hydraulic single-flow transmission, gear-dual-ring composite transmission, gear-hydraulic composite transmission and dual-ring-hydraulic composite transmission are integrated.
