Abstract
A multi-mode hydro-mechanical hybrid transmission device includes an input member, a hydraulic transmission mechanism, a mechanical transmission mechanism, a convergence mechanism, an output member, a clutch assembly, and a brake assembly. The clutch assembly connects an output end of the input member to an input end of the hydraulic transmission mechanism, the mechanical transmission mechanism, and the convergence mechanism. The clutch assembly connects an output end of the hydraulic transmission mechanism to the convergence mechanism. The clutch assembly connects the mechanical transmission mechanism to the convergence mechanism. The convergence mechanism is connected to the output member. Continuously changing transmission ratios are provided between the input member and the output member by adjusting a displacement ratio of the hydraulic transmission mechanism and selectively controlling engagement of the clutch assembly and the brake assembly.
