摘要： A work machine gear shifting control device is capable of readily identifying the cause of failure in learning the clutch hydraulic pressure for operating a transmission clutch. A transmission gear shifting control section 46 is provided for each of clutches 61-65, and performs a learning process in which each of a plurality of handling processes learns the clutch hydraulic pressure for each of the clutches 61-65 and determines the clutch hydraulic pressure characteristic values for operating the individual clutches. Further, the transmission gear shifting control section 46 performs a learning monitoring process in each of the plurality of handling processes to formulate an error judgment, which indicates whether learning has failed in each of the plurality of subprocesses, and displays the result of the judgment.

摘要： A work machine gear shifting control system provides gear shifting conditions for an automatic gear shifting mode in accordance with work site conditions. An area 62 of a display device 49 displays a permissible velocity setting range and setup operation guidance, and another area 64 shows guidance to indicate whether the setting is acceptable or unacceptable. When the traveling velocity falls within the permissible velocity setting range, the displayed guidance changes to indicate that the setting is acceptable. When, in this instance, an operator presses a setup switch 23 with desired timing, a transmission gear shifting control section 45 acquires the prevailing vehicle velocity and velocity ratio (or vehicle velocity), and stores adjustment values in an adjustment value storage section 43 so that the vehicle velocity and velocity ratio become the gear shifting control threshold values for normal gear shifting control (steps S535 to S545).

摘要： A traveling hydraulic working machine has a target revolution speed of an engine commanded by an input and sensors for detecting an operating situation of a hydraulic actuator and an operating situation of a traveling system. A prime-mover revolution speed control modifies the target revolution speed of the prime mover when the operating situation of the hydraulic actuator and the operating situation of the traveling system come into respective particular states, and controls the revolution speed of the prime mover, With the traveling hydraulic working machine, in the combined operation of traveling and working a hydraulic actuator, work can be performed on the basis of the engine revolution speed intended by an operator. When a working load varies, the engine revolution speed is automatically controlled.

摘要： A modification torque computing unit 83 computes 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.
