Abstract
A gear-hydraulic-rhombic pyramid integrated multi-mode hybrid transmission device includes an input assembly, a hydraulic transmission mechanism, a front planetary gear mechanism, a rhombic pyramid-type continuously variable transmission mechanism, a rear planetary gear mechanism, an output assembly, a clutch assembly, and a brake assembly. The clutch assembly connects an output end of the input assembly to an input end of the hydraulic transmission mechanism and an input end of the front planetary gear mechanism. The clutch assembly connects an output end of the hydraulic transmission mechanism to the front planetary gear mechanism and the rear planetary gear mechanism. The clutch assembly connects the front planetary gear mechanism, the rhombic pyramid-type continuously variable transmission mechanism, the rear planetary gear mechanism, and the output assembly in sequence. The clutch assembly and the brake assembly provide a continuous transmission ratio between the input assembly and the output assembly.
