Continuous formulation of the layout of a hydromechanical transmission
Mechanism and Machine Theory, 2019Abstract In this paper, an analytical formulation of the layouts of three-shaft hydromechanical transmissions is presented. The formulation was obtained starting from the Willis equation for the planetary gears. Its graphical representation results in a polar plot dependent only on the angular coordinate: by varying the latter between 0 and 2π, all ...

Design of hydromechanical transmission using network analysis
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2005A systematic approach to the design of a three-shaft hydromechanical transmission (HMT) is proposed. The three-shaft HMT is classified into 12 basic configurations depending on the planetary gear position connected with the hydrostatic unit (HSU) at the input and the output shafts.

Optimization of components and layouts of hydromechanical transmissions
International Journal of Fluid Power, 2017In the agricultural and work machine sectors, hydromechanical transmission competes with traditional mechanical transmission. However, the double energy conversion taking place in hydrostatic transmission lowers the efficiency of the entire transmission.
