Patent number: 10676898Abstract: In a hydraulic drive system of a work machine which drives a plurality of actuators using three or more pumps, for an operation not including traveling, a highly efficient combined operation in a front implement and excellent combined operability of a swing and the front implement are enabled, while for an operation including traveling, a highly efficient traveling operation and a highly efficient combined operation of traveling and the front implement are enabled, and a sufficient operation speed of the front implement is achieved. To this end, each of the flow rates of the first, second, and third pumps (101, 201, 301) can be controlled independently by performing the load sensing control, and in a combined operation for driving a boom (511) and an arm (512), ether one of them is driven by the first pump while the other one is driven by the second pump, and the swing is driven by the third pump.Type: GrantFiled: December 14, 2017Date of Patent: June 9, 2020Assignee: Hibachi Construction Machinery Tierra Co., Ltd.Inventors: Kiwamu Takahashi, Taihei Maehara, Kazushige Mori, Yoshifumi Takebayashi, Natsuki Nakamura

Patent number: 10655647Abstract: Pressure compensating valves not fully closing at the stroke end are employed, and upon the operator's operation for the traveling, pilot primary pressure is reduced and supplied to remote control valves 34c-34h of non-travel operating devices. Thus, the inflow of the hydraulic fluid into non-travel actuators is suppressed and a necessary amount of hydraulic fluid for travel motors is secured in travel combined operation. Accordingly, when saturation occurs in a construction machine's hydraulic drive system performing the load sensing control due to combined operation with a great load pressure difference between two actuators, deceleration/stoppage of an actuator on the low load pressure side is prevented by preventing full closure of the pressure compensating valve on the low load pressure side, while also preventing deceleration/stoppage of a high load pressure actuator by securing a necessary amount of hydraulic fluid for the high load pressure actuator.Type: GrantFiled: January 30, 2018Date of Patent: May 19, 2020Assignee: HITACHI CONSTRUCTION MACHINERY TIERRA CO., LTD.Inventors: Yoshifumi Takebayashi, Kiwamu Takahashi, Kazushige Mori, Natsuki Nakamura
