Transmission apparatus for a working vehicle

摘要

A working vehicle comprises: a power source having an output shaft; axles; a cargo deck (8); and a transmission apparatus (10) for driving axles disposed below the cargo deck. The transmission apparatus (10) includes an input shaft (11) drivingly connected to the output shaft (31) of the power source, a hydromechanical stepless transmission driven by the input shaft, and a differential gear assembly (70) differentially connecting the axles to each other. The hydromechanical stepless transmission includes a planetary gear assembly (50) and a hydrostatic stepless transmission (40) drivingly connected to the planetary gear assembly (50). The differential gear assembly (70) is drivingly connected to the hydromechanical stepless transmission.
