    摘要: A hydraulic transmission comprising a variable displacement pump and motor, at least one of which has cylinders having valves which are controllable on each cycle of cylinder working volume to determine the net displacement of working fluid by the cylinder. The transmission has a controller which determines a displacement of the pump and the motor. The displacement of the pump and/or motor is controlled to avoid the pump and/or motor generating vibrations with frequencies which correspond to resonant frequencies of portions of a machine which are part of or in mechanical communication with the hydraulic transmission and which arise from the pattern of active and inactive cycles of cylinder working volume, taking into account the speed of rotation of the rotatable shaft of the pump and/or motor.

    摘要: A hydraulic machine is provided with: a valve configured to switch a state of communication between a hydraulic chamber formed by a cylinder and a piston and an outside of the hydraulic chamber by moving the movable unit; anda controller for controlling an open/close operation of the valve; and a signal detector for detecting a signal which the solenoid coil generates when the movable unit moves from a first position to a second position. The controller is configured to, in a case where the signal is not detected when a phase angle indicating a position of the piston in a first range including a target phase angle for moving the movable unit to the second position: execute a control mode for controlling an actuator to a non-driving state; and determine an operation state of the valve based on whether or not the signal is detected when the control mode is executed and the phase angle of the piston is in a second range which is at least in part a range excluding the first range.

A hydraulic transmission comprises: a hydraulic pump of a variable displacement type configured to be driven by a mechanical energy inputted into a rotation shaft; a hydraulic motor of a variable displacement type configured to be driven by a pressurized oil from the hydraulic pump; a high pressure oil line for introducing the pressurized oil from the hydraulic pump to the hydraulic motor; and a controller for controlling a displacement of each of the hydraulic pump and the hydraulic motor, wherein, the controller is configured to:
    when at least one of the displacement of the hydraulic motor or a pressure of the pressurized oil is less than a first threshold value, control the displacement of the hydraulic motor so as to adjust the pressure of the pressurized oil in the high pressure oil line to a target pressure value; and when at least one of the displacement of the hydraulic motor or the pressure of the pressurized oil is not less than the first threshold value, reduce the displacement of the hydraulic pump so as to prevent the pressure of the pressurized oil from increasing suddenly responsive to a rapid increase of the mechanical energy inputted into the rotation shaft.

    摘要: A hydraulic transmission comprising a variable displacement pump and motor, at least one of which has cylinders having valves which are controllable on each cycle of cylinder working volume to determine the net displacement of working fluid by the cylinder. The transmission has a controller which determines a displacement of the pump and the motor. The displacement of the pump and/or motor is controlled to attenuate oscillations in parameters such as the pump torque or the pressure in the high pressure working fluid line connecting the pump to the motor. A demand signal, such as a torque demand signal is processed taking into account a damping signal which is calculated to compensate for variations in the amplitude and phase of the response of the net displacement by said cylinders to the received demand signal with the frequency of the one or more oscillations and the speed of rotation of the rotatable shaft of the pump or motor respectively.
