    摘要: A drive train of a vehicle has a drive motor and a traction drive driven by the drive motor. A hydraulic work system has at least one hydraulic pump driven by the drive motor. To deliver torque into the drive train and/or to absorb torque from the drive train, the drive train is provided with an additional hydraulic machine which can be placed in communication with a hydraulic pressure accumulator and/or a tank and can be operated as a pump and a motor in the same direction of rotation. The hydraulic machine has an inlet connection and an outlet connection and a switching valve device is provided to control the connection of the inlet connection and the outlet connection with the pressure accumulator or the tank.

    摘要: A rollback prevention system is disclosed for use with a mobile machine having an engine and a transmission. The rollback prevention system may have an input device configured to receive an input indicative of a desired travel direction of the mobile machine, a sensor configured to generate a signal indicative of an actual travel direction of the mobile machine, and a controller in communication with the input device, the sensor, the engine, and the transmission. The controller may be configured to make a determination that the actual travel direction of the mobile machine is opposite the desired travel direction based on the signal, and determine a load on the transmission. The controller may also be configured to selectively increase a torque output of the transmission based on the determination only when the load on the transmission is less than a threshold value.

    摘要: A hybrid-driven hydraulic work machine maintains the torque of the engine at a prescribed value when the load on a hydraulic pump is higher than the rated power of the engine and the electric assist motor assists the torque of the engine. Control of the engine revolution speed is based on the target revolution speed of the engine; engine load calculation; and at least one of: electric motor power running calculation which calculates a differential revolution speed between the target engine revolution speed and the revolution speed of the engine and performs power running control on the electric assist motor depending on the differential revolution speed when the engine load is a prescribed value or higher; and a hydraulic pump absorption torque calculation which performs reduction control on absorption torque of the hydraulic pump depending on the differential revolution speed when the engine load is a prescribed value or higher.

    摘要: An anti-rebounding control apparatus is provided, which includes an anti-rebounding controller outputting a first command for setting a torque limit value to “0” if an electric motor speed value is equal to or smaller than an upper threshold value and equal to or larger than a lower threshold value in the case where a speed command value of “0” is input and outputting a second command for setting the torque limit value to a maximum value if the electric motor speed value is smaller than the lower threshold value, a torque regulator setting the torque limit value to “0” when the first command is input and setting the torque limit value to the maximum value when the second command is input, and an electric motor inverter intercepting a power that is supplied to an electric motor if the torque limit value is set to “0” and re-supplying the power to the electric motor if the torque limit value is set to the maximum value. Accordingly, the same performance as an anti-rebounding system that is used in a swing system of an existing hydraulic excavator can be implemented even in a system that performs a swing operation using an electric motor such as a hybrid (or electric) excavator.
