摘要： A hydraulic drive traveling system has a pressure compensated low control valve connected between a hydraulic pump and a variable displacement type hydraulic motor for controlling a flow rate of the hydraulic fluid supplied to the motor. The flow rate is controlled in accordance with the delivery pressure of the pump and demanded traveling speed of the motor. When the delivery pressure of the pump is at a high level, the motor is shifted to a first capacity. When the delivery pressure of the pump is low, the motor is shifted to either the second capacity or the first capacity depending upon the demanded traveling speed.

摘要： A hydraulic system for a construction machine comprising plural hydraulic actuators (23-28) driven by fluid supplied from a pump (22), first and second flow control valves (29-34) for controlling flows of fluid supplied to the first and second actuators, and first and second distribution compensating valves (35-40) for controlling first differential pressure (.DELTA.P v1-.DELTA.P v6) produced between inlets and outlets of the first and second flow control valves. The first and second distribution compensating valves have respective drives (45-50, 35c-40c) for applying control forces (Fc1-Fc2) in accordance with the second differential pressure to the associated distribution compensating valves, to thereby set target values of the first differential pressures. The hydraulic system includes first means (59) for detecting the second differential pressure (.DELTA.P LS) from the discharge pressure (P s) of the pump (22) and the maximum load pressure (P amax) out of the first and second actuators; second means (61) for calculating individual values (Fc1-Fc6), as values of the control forces applied from the drives (45-50, 35C-40C) of the first and second distribution compensating valves (35-40), in accordance with at least the second differential pressure detected by the first means; and first and second control pressure generators (62a-62f) provided in association with the first and second distribution compensating valves. The first and second control pressure generators (62a-62f) produce control pressures (P c1-P c6) dependent on the individual values obtained by the second means and output the control pressures to the drives (35c-40c) of the first and second distribution compensating valves.

摘要： A controller 24 includes function generators 151, 152. The function generator 151 is set to have such a characteristic that as the detected value P.sub.N of a negative control pressure from a pressure sensor 21 is reduced, a first target tilting amount .theta..sub.N increases from a minimum value to a maximum value, and the function generator 152 is set to have such a characteristic that as the detected value P.sub.B of a control input (pilot pressure) for driving a boom cylinder 6 is increased, a second target tilting amount .theta..sub.B increases from a predetermined minimum value to the same maximum value as the above maximum value. Minimum one of the two target tilting amounts from both the function generators is selected, and a proportional solenoid valve 25 is driven based on the selected minimum tilting amount. This makes it possible to surely suppress an unwanted speed increase of a specific hydraulic actuator other than a boom cylinder, such as a swing motor 9, that would be caused when the tilting amount is controlled based on only the negative control pressure.

摘要： An antitheft system can be provided by constructing such that, when a stop signal has been inputted from an engine 7, a main controller 2 outputs, until a first predetermined time Ts elapses, a turn-on signal to switches 8, 9 to perform a similar antitheft processing as in an operation of the engine 7 and after an elapse of the first predetermined time Ts, instructs the switch 9 to repeat a turn-on and turn-off at predetermined time intervals Δt, and, whenever the switch 9 is brought into a turned-on position, detects a position at that time by a position detecting controller 3 and compares the position with a position at the time of an engine stop to determine whether or not a theft has taken place. Owing to this construction, it is no longer necessary to always feed power to the position detecting controller 3 during the stop of the engine 7, thereby making it possible to cut down the feeding of as much power to the controller 3 as a time elapsed during which the switch 9 is kept off. The antitheft system can, therefore, minimize the power consumption of a control system during the engine stop.

摘要： In the arm-crowding or track operation, a calculating portion (700d2 or 700d4) calculates a modification gain (KAC or KTR) depending on an operation pilot pressure and a calculating portion (700g) calculates a decrease modification (DND) based on the KAC or KTR, while a calculating portion (700m or 700p) calculates a modification gain (KACH or KTRH) depending on an operation pilot pressure and calculating portions (700q-700s) calculate an increase modification (DNH) based on the KACH or KTRH. A reference target engine revolution speed NR0 is modified using the DND and DNH. In other operations than the arm-crowding and track operations, NR0 is modified using only the decrease modification (DND) calculated from the modification gain just depending on the operation pilot pressure. In the operation where an engine revolution speed is desired to become higher as an actuator load increases, the engine revolution speed can be controlled in accordance with change of the actuator load as well. In other operations, the engine revolution speed can be controlled just depending on the direction and input amount in and by which corresponding operation instructing apparatus is operated.

摘要： When the pump pressure detected through a pressure detecting line 48 is raised higher than a first predetermined pressure Pd1, a recovery switching valve 44 is shifted to a valve-closed position to cease the recovery function. At this time, the pump delivery pressure detected through a pressure detecting line 51 is higher than a second predetermined pressure Pd1* close to the first predetermined pressure Pd1, and an engine speed increasing device 52 controls an engine controller 11 to increase the rotational speed of an engine 10, thereby increasing the pump delivery rate. Thus, it is possible to make small speed change of an actuator and to increase working efficiency with no deterioration in operability, even when a recovery function is ceased.
