Method of operation of a hydrostatic -mechanical power transmission and hydrostatic -mechanical power transmission

摘要

A procedure for operating a hydrostatic -mechanical power -switching gearbox (3) of a machine is proposed (2),comprising a mechanical power branch (9) and a hydrostatic power branch (7) with a variable (4),where the speed of a variable drift wave (8) is controlled by an electronic control device (14) on the basis of a time signal sequence (20) of a control signal: according to the invention, for at least one load -setting situation (22),where the speed of the variable drift shaft (8) is changed by a load change,present load over at least one sensor (15, 16,17) determines and determines a correction value (24) depending on the determined load;adjusting the control signal to a correction point (27),so that the change in speed caused by the load -setting situation (22) is reduced by the variable -drift wave (8). A hydrostatic -mechanical power transmission (3) is also proposed.
