MULTI-MODE HYBRID POWER-COMPOUND TRANSMISSION POWER TRANSMISSION DEVICE

WIPO Patent Application WO/2021/138944

A1

A multi-mode hybrid power-compound transmission power transmission device, comprising an internal combustion engine power system (1), a planetary gear assembly, an output member, an electric motor power system (6), a hydraulic transmission system (7), a clutch assembly and a brake assembly. The planetary gear assembly comprises at least three planetary gear trains, the internal combustion engine power system (1) is connected to the hydraulic transmission system (7), the output member is connected to the planetary gear assembly, and the clutch assembly respectively connects the internal combustion engine power system (1), the electric motor power system (6) and the hydraulic transmission system (7) to the planetary gear assembly, and the clutch assembly and the brake assembly provide a continuous transmission ratio of the internal combustion engine power system and/or the electric motor power system to the output member. By means of a combination of a transmission device structure design and a braking energy management system, the transmission device achieves the recovery and release of braking energy, increasing the energy utilization rate.
