摘要:
A hydrostatic mechanical transmission according to the disclosure includes: a hydrostatic transmission which transmits power generated in an engine using a pump and a motor; a main transmission unit which transmits the engine power to a final driving unit through a driving shaft; a complex planetary gear which synthesizes and transmits the engine power transmitted from the hydrostatic transmission and the main transmission unit; and an automatic manual sub-gearshift which receives the synthesized engine power from the complex planetary gear so as to perform a transmission function and transmits the engine power to the final driving unit.
