  ,, equal-ratio four-stage stepless shift is formed between the hydraulic transmission H2, the hydro-mechanical transmission HM1, the hydro-mechanical transmission HM2, the hydro-mechanical transmission HM3, and the hydro-mechanical transmission HM4 by adjusting the displacement ratio of the hydraulic transmission mechanism and selectively controlling the clutch assembly, wherein k1 is the planetary gear characteristic parameter of the front planetary gear mechanism and k2 is a planetary gear characteristic parameter of the rear planetary gear mechanism.
