Hydro-mechanical hybrid transmission device with two hydraulic transmission mechanisms

A hydro-mechanical hybrid transmission device with two hydraulic transmission mechanisms, comprising

• an input member,
• a second hydraulic transmission mechanism,
• a rear planetary gear mechanism,
• an output member,
• a first hydraulic transmission mechanism,
• a front planetary gear mechanism,
• a clutch assembly, and
• a brake assembly, wherein
• the clutch assembly connects the input member to the front planetary gear mechanism, the second hydraulic transmission mechanism, and the first hydraulic transmission mechanism,
• the clutch assembly connects an output end of the first hydraulic transmission mechanism to the front planetary gear mechanism,
• the clutch assembly connects the rear planetary gear mechanism to an output end of the second hydraulic transmission mechanism and the front planetary gear mechanism, and
• the clutch assembly connects an output end of the rear planetary gear mechanism to the output member;
• and
• the clutch assembly and the brake assembly provide a continuous transmission ratio between the input member and the output member.
