Latest Patents
Yasuharu Gotou holds a patent for a hydraulic drive system specifically designed for hydraulic work vehicles. This system features a signal guide system that directs the delivery pressure of a pump as a command pressure through a line and a port. Additionally, it includes another signal guide system that manages the pilot pressure of a pilot pump as a separate command pressure. The system is equipped with a tilting control unit that regulates the pump's displacement based on the command pressures. Furthermore, a controller is integrated, which has a command current-setting unit to establish a relationship between the target engine speed and command current. The system also includes a solenoid-operated proportional valve that allows the pilot pressure to pass through when no drive signal is outputted, while reducing the opening to adjust the pilot pressure when a drive signal is present. This innovative design enhances the operational capabilities of hydraulic work vehicles.
