Abstract [en]

To increase energy efficiency and lower emissions in construction machines, the use ofhydromechanical power split drive trains shows high potential. The possibility of usingmultiple gear speeds without losing traction force makes the power split architecture especiallysuitable for heavier wheel loaders. This paper analyses two known concepts ofmulti-mode power split transmissions suitable for the wheel loader application and comparesthe solutions based on energy efficiency. The concepts are scalable in the sense thatadditional modes can be used without necessarily adding complexity to the transmission.Simulations are made with respect to steady-state transmission losses and the relationbetween number of modes and transmission efficiency is shown for each of the proposedconcepts. The operational characteristics of the hydraulic displacement machines stronglyaffects the transmission efficiency and the design choice of number of transmissionmodes.
