    摘要: A torque transfer coupling includes first and second rotary members. A transfer clutch operatively connects the first and second rotary members. A piston, disposed in a piston chamber, is actuable to engage the transfer clutch. A hydraulic pump in fluid communication with a sump containing hydraulic fluid has a first pump member fixed for rotation with the first rotary member and a second pump member fixed for rotation with the second rotary member such that relative rotation between the first and the second pump members generates a fluid pumping action. A first flow path supplies hydraulic fluid from the hydraulic pump to the piston chamber. A second flow path supplies hydraulic fluid from the piston chamber to a control valve for regulating the pressure of the hydraulic fluid supplied to the piston chamber. The second flow path includes an aperture extending through the second pump member.

    摘要: A hydraulic operating circuit for friction power-shift clutches (1a-2b) for tractor gearboxes, in which the hydraulic actuators (2) of the clutches are operatively associated with respective valve units (13, 18) which are connected in series and are operated by electronically-controlled piloting means adapted to achieve the combined engagement and disengagement of the clutches for effecting changes of speed ratio without interrupting the transmission of torque. The circuit enables the simultaneous modulation of several clutches by a single electronically-controlled, proportional pressure reducing valve (20), the pressure of the remaining clutches being kept unchanged.
    The proportional valve (20) enables the piloting of the bringing together of the friction discs of the clutches, the modulation and the maintenance of the pressure.

    摘要: The invention relates to a hydraulic system for an automatic gearbox, more particularly a dual-clutch gearbox, for a motor vehicle, comprising a high-pressure circuit (H) which includes a pressure accumulator (25), at least one clutch (K1, K2) and actuators (22), and comprising a low-pressure circuit (N) for cooling the clutch (K1, K2), the high-pressure circuit (H) and the low-pressure circuit (N) each containing a hydraulic cooling pump (59) and a hydraulic charging pump (53) that can be driven by a shared electric motor (57); and comprising a controller (39) which, when it is detected that the pressure accumulator needs to be charged, controls the electric motor (57) to run at a charging setpoint speed (n
    soll, laden ), and/or, when it is detected that cooling is needed or another need exists, controls the electric motor (57) to run at a cooling setpoint speed or another setpoint speed (n
    soll, kühlen ). According to the invention, when the pressure accumulator does not need to be charged and there is no need for cooling and no other need, the controller (39) reduces the setpoint speed (n
    soll ) to zero for a specified period (Δt
    aus ). At the end of the period (Δt
    aus ) the controller (39) controls the electric motor (57) to run at least at the test speed (n
    prüf ).
