摘要： A work machine enabling a hybrid drive system to be directly driven by energy contained in a return fluid discharged from a hydraulic actuator. The work machine includes a hydraulic actuator control circuit and a swing control circuit. The hydraulic actuator control circuit serves to control hydraulic fluid supplied from pumps of a hybrid drive system to travel motors and work actuators. The swing control circuit serves to control a swing motor generator, which functions as an electric motor and, during braking of rotating motion of the upper structure, functions as a generator. The hydraulic actuator control circuit includes an energy recovery motor provided in a return passage, though which return fluid recovered from a work actuator flows. The energy recovery motor is adapted to be driven by return fluid and thereby drive a motor generator of the hybrid drive system.

摘要： A swing control circuit is provided separately from a hydraulic actuator control circuit. The swing control circuit includes a swing pump motor connected to closed circuits of a swing motor through a solenoid valve that serves as a directional control valve. A swing motor generator is connected to the swing pump motor. The swing motor generator is connected to an electric power storage device of a hybrid type drive system. An exterior-connecting passage for feeding hydraulic fluid to hydraulic actuators of a lower structure and a work equipment is drawn from a pipeline between the swing pump motor and the solenoid valve. A connecting passage solenoid valve is disposed in the exterior-connecting passage. The invention enables hydraulic energy generated in the swing system to be directly fed to the outside of the swing system.

摘要： This invention provides a system for recording operation data of a machine, wherein a program for converting signals stored through a sensor or measuring means into operation data in conformity with the increase or alteration of the sensor or measuring means due to the operation status of the machine or to the type of the component of the machine is preliminarily stored in one or separate card-type external memory or other transportable external memory. The terminal of the system is designed to allow an connection of various kinds of the sensor or measuring means. Accordingly, it is possible to conduct processing and recording of various kinds of operation data by exchanging the external memory stored with a prescribed operation data-processing program, or by changing the writing of the program. It is also possible to record operation data in the external memory stored with the operation data-processing program after the program is read out to simplify the operation of an operator.

摘要： A hydraulic control system for a work machine is disclosed. The hydraulic control system has a fluid actuator, a supply of pressurized fluid, and a control valve movable to selectively pass pressurized fluid to the fluid actuator. The hydraulic control system also has a sensor configured to sense the pressure of the pressurized fluid passed to the fluid actuator and a controller in communication with the control valve and the sensor. The controller is configured to receive an input indicative of a desired velocity of the fluid actuator and to determine a fluid flow rate corresponding to the desired velocity. The controller is also configured to determine a ratio of the sensed pressure to a stall pressure of the supply and to scale down the determined flow rate an amount based on the determined ratio. The controller is further configured to move the control valve an amount corresponding to the scaled down flow rate.
