Abstract
A hydro-mechanical hybrid transmission device with two hydraulic transmission mechanisms includes 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. The clutch assembly connects the input member to the front planetary gear mechanism, the second hydraulic transmission mechanism, and the first hydraulic transmission mechanism, connects an output end of the first hydraulic transmission mechanism to the front planetary gear mechanism, connects the rear planetary gear mechanism to an output end of the second hydraulic transmission mechanism and the front planetary gear mechanism, and connects the rear planetary gear mechanism to the output member. The clutch assembly and the brake assembly provide a continuous transmission ratio between the input member and the output member.
