METHOD OF ASSEMBLY FOR HYDROMECHANICAL TRANSMISSION

摘要

A method of assembly (140) for a hydromechanical powersplit transmission (11) and a method of disassembly and repair (140) includes providing a connecting plate (25) at step (140a). Primary and secondary pump motor unit drive shafts (44, 45) and rotating groups (42a, 42b, 43a, 43b) and housing (26) are assembled onto the connecting plate (25) at steps (140b-140d) to provide a hydraulic unit (23) on one side (23a) of the connecting plate (25) for the transmission (11). Primary drive gear (76) and planetary gear set (71) and front gear housing (29a) are assembled onto connecting plate 25 at steps (140e-140h). Secondary drive gears (78) and (79) and rear gear housing (29b) and valves (53, 54, 55) and (56) are assembled onto connecting plate (25) at steps (140i-140k) to provide a gear unit (24) for the transmission (11) that is assembled integrally with the hydraulic unit (23).
