摘要： In a hydraulic machine such as, for example, a hydraulic excavator equipped with hydraulic actuators, a hydraulic driving method and a hydraulic driving apparatus enable all the hydraulic actuators to be operated according to normal operational-speed characteristics (first mode). The method and the apparatus alter the operational-speed characteristics of at least one of the hydraulic actuators, according to other characteristics (second mode), in accordance with working contents. The actuators altered in this manner can be operated according to the operational-speed characteristics of the second mode, without exerting an influence upon the operational-speed characteristics of the remaining hydraulic actuators.

摘要： A modification torque ΔT and a torque converter speed ratio e is computed from input and output revolution speeds of a torque converter 31. A first determination coefficient α corresponding to the speed ratio e, and a second determination coefficient β corresponding to a pump pressure are computed. A selector 87 selects the smaller one of these coefficients as a determination coefficient γ, and the modification torque ΔT is multiplied by γ to provide a modification torque ΔTA. An adder 89 adds the modification torque ΔTA (negative value) to a pump base torque TR to provide a modified pump base torque TRA, whereby a maximum pump absorption torque TRA is controlled so as to become TRA. The maximum pump torque reducing control can then be performed while accurately confirming a work situation during the combined operation of travel and a working actuator.

摘要： A joining directional control valve 13 is disposed to supply, to an arm cylinder 4, not only a hydraulic fluid delivered from a first hydraulic pump 1, but also a hydraulic fluid delivered from a second hydraulic pump 2 when an arm directional control valve 14 is driven. Respective delivery pressures of the hydraulic pumps 1, 2 are detected by pressure sensors 101, 102, and the opening area of a recovery control valve 6 is controlled depending on a lower one of the detected pressures from the pressure sensors 101, 102 such that, even in the combined operation of the arm cylinder 4 and another actuator 3, 4, the hydraulic fluid can be recovered for return to the arm cylinder 4 when the load pressure of the arm cylinder 4 is low. Thus, by supplying the hydraulic fluids from the two hydraulic pumps to the particular actuator for which the hydraulic fluid is to be recovered, a recovery flow rate is ensured when the load of the particular actuator is low in the combined operation.
