- the invention further relates to a method for operating such a hydrostatically actuated clutch system.
- German Offenlegungsschrift DE 10 2013 207 263 A1 discloses a method and a device for adapting a clutch characteristic of an automatically operable friction clutch, with a clutch actuator having an actuating device with a fluid column between a master cylinder and a slave cylinder, wherein the
- Coupling actuator has a sniffer opening.
- German Offenlegungsschrift DE 10 2013 205 237 A1 discloses a method for controlling an actuator system for the hydraulic actuation of a clutch, wherein the actuator system has a master cylinder with a master piston, a secondary reservoir for receiving hydraulic fluid, a connection opening between the slave reservoir and the master cylinder Hydrostatic actuator for controlling a position of the master piston and a control device for controlling the hydrostatic actuator has.
- the object of the invention is to simplify the hydrostatic actuation of a clutch, in particular a pulse clutch of a hybrid drive.
- the object is achieved in a hydrostatically actuated clutch system, with a hydrostatic clutch actuator for hydrostatic actuation of a clutch, in particular a pulse clutch of a hybrid drive, characterized in that the hydrostatic
- the hybrid drive is a drive which, in addition to a primary drive, for example an internal combustion engine, which is also referred to as an internal combustion engine, also comprises a secondary drive, for example an electric machine.
- the primary drive and the secondary drive may be used together or alone to drive a motor vehicle equipped with the hybrid drive.
- the motor vehicle with the hybrid drive is also referred to as a hybrid vehicle.
- the clutch is preferably located in the hybrid vehicle between the primary drive and the secondary drive arranged. By opening the clutch, the primary drive can be disconnected from the drive train. If the hybrid vehicle is driven solely by the secondary drive, then it is possible in the context of a so-called impulse start to switch on the primary drive while driving.
- By actively openable valve device advantageously a very fast closing of the clutch is possible.
- a preferred embodiment of the hydrostatically actuated clutch system is characterized in that the clutch is designed as a disconnect clutch with a pulse start function.
- the separating clutch is designed as a normally closed clutch, which is closed in the unactuated state and is opened by the hydrostatic clutch actuator.
- a further preferred embodiment of the hydrostatically actuated clutch system is characterized in that the clutch in an unactuated state by a spring device, in particular a disc spring device, is closed and can be opened by the hydrostatic clutch actuator.
- the hydrostatic clutch actuator has proven to be advantageous in the context of the present invention in view of the available space in a hybrid vehicle. However, it has also been found within the scope of the present invention that the hydrostatic clutch actuator can not close the clutch fast enough. Due to the supposed disadvantage of an additional valve device, a very fast closing of the clutch can also be made possible with the hydrostatic clutch actuator.
- the inventive combination of the hydrostatic clutch actuator with the actively opening valve device, the clutch can be extremely fast, for example, within less than a hundred milliseconds, completely closed.
- a further preferred embodiment of the hydrostatically actuated clutch system is characterized in that the valve device is designed and arranged so that the valve device allows rapid pressure reduction on a donor side.
- a master cylinder On the encoder side, for example, a master cylinder is arranged with a master piston, which can be moved by an electric motor via a gear and a piston rod in the master cylinder.
- the master cylinder is connected via a hydrostatic path with a slave cylinder, in which a slave piston is arranged.
- the clutch can be operated, in particular be opened.
- the actively opening Valve device is assigned, for example, the master cylinder on the encoder side. The pressure in the master cylinder can be reduced quickly via the active opening valve device.
- a further preferred embodiment of the hydrostatically actuated clutch system is characterized in that the valve device has a clutch pressure port and a tank port, which allows a rapid pressure reduction to open the clutch.
- the tank connection is connected, for example, to a reservoir.
- the reservoir contains hydraulic medium which, for example, is exposed to ambient pressure.
- a further preferred embodiment of the hydrostatically actuated clutch system is characterized in that the clutch pressure port and the tank port of the valve device are closed by a valve piston in a closed position of the valve device.
- the valve piston is biased by a biasing spring into its closed position, for example.
- electromagnetic actuation of the valve piston can be moved from its closed position to an open position in which the coupling pressure port is connected to the tank port.
- a further preferred embodiment of the hydrostatically actuated clutch system is characterized in that the valve piston radially inwardly defines an annular space which is delimited in the axial direction by two seals and which is bounded radially on the outside by a valve housing with the tank connection.
- the connections of the valve device are preferably designed as or as similar as sniffer holes in conventional clutch master cylinders.
- sniffer holes in conventional clutch master cylinders.
- a pressure can be built up by a master piston movement in the master cylinder, which is then selectively discharged through the actively opening valve device, which can be sensed for diagnostic purposes.
- This "diagnostic operation" can be used, for example, to provide a signal when the system starts up that the clutch, in particular the pulse clutch, is available.
- the above-stated object is alternatively or additionally achieved in that the opened clutch is quickly closed by an active opening of the valve device. It is deliberately not used for actively closing the clutch, the hydrostatic clutch actuator, because this is too slow.
- a preferred embodiment of the method is characterized in that when closing the clutch by the active opening of the valve device, a master piston is moved in the direction of a minimum position.
- the minimum position of the master piston corresponds to an end position of the master piston.
- a further preferred embodiment of the method is characterized in that the valve device remains open until the master piston has reached its minimum position. Only then is the system fully functional again. By keeping the valve device open, it is advantageously prevented that a vacuum is created in the master cylinder or incorrectly air enters the master cylinder past the seals.

- a donor side 15 a designated as a master cylinder cylinder 4 with a piston or master piston 19 is arranged.
- the hydraulic clutch system 1 comprises on the encoder side 15, a control unit 2 as a control unit, which drives an actuator 3.
- a control unit 2 as a control unit, which drives an actuator 3.
- the volume of the cylinder 4 is changed, whereby a pressure P is built up in the cylinder 4, via a pressure medium 7 via a hydraulic line 9 is transmitted to the slave side 16 of the hydraulic clutch system 1.
- the hydraulic line 9 is in terms of their length and shape of the space situation of
- the pressure P in the cylinder 4 on the encoder side 15 of the hydraulic clutch system 1 can be determined by means of a first sensor 5.
- the first sensor 5 is preferably a pressure sensor.
- the second sensor 6 can either be a displacement sensor which determines the distance covered by the actuator relative to a reference position, or preferably a sensor which detects the number of revolutions of the actuator drive, which can be, for example, an electric motor 10, and determines the actuator travel therefrom.
- the cross section of a sniffer opening 18 for volume compensation is advantageously carried out with the lowest possible flow resistance.
- the clutch 8 is designed as a disconnect clutch and biased by a spring device 20, in particular a disc spring device in its closed position.
- a valve device 40 is assigned to the master cylinder 4.
- the valve device 40 is designed as a pressure reduction valve 42, which allows a rapid pressure reduction in the master cylinder 4, if necessary.
- the pressure reduction valve 42 has a pressure reduction opening 44, which is also referred to as a tank connection.
- the pressure reduction valve 42 to the reservoir 17th
- the pressure reduction valve 42 is connected. Via an inlet opening 46, which is also referred to as a coupling pressure port, the pressure reduction valve 42 is connected to the master cylinder 4. The pressure reduction valve 42 is actuated via an actuator 60.
- a connection between the master cylinder 4 and the reservoir 17 is interrupted.
- a connection between the inlet opening or the pressure connection or coupling pressure connection 46 and the pressure reduction opening or the tank connection 44 is released by the pressure reduction valve 42.
- valve means 40 with the pressure reduction valve 42 for
- the pressure reduction valve 42 comprises a pressure reduction opening 44 in a valve housing 45 of the valve device 40.
- About the pressure reduction opening 44 can pressure in a low pressure area or in a
- Hydraulic medium reservoir (17 in Figure 1) are degraded, which is acted upon by low pressure or ambient pressure.
- the valve housing 45 further includes an input port 46, which is also referred to as a clutch pressure port.
- the valve housing 45 includes a receiving space 48, in which a valve piston 50 is received reciprocally movable.
- the valve piston 50, two seals 51, 52 are assigned in a similar manner as in a master cylinder with a sniffer bore.
- the seals 51, 52 are axially fixed in the valve housing 45.
- the seals 51, 52 are designed as ring seals, the radially inner one
- the valve piston 50 is biased by a closing spring 55 in its closed position shown in Figure 2.
- a closing spring 55 In the closed position, the valve piston 50, with its upper end in FIGS. 2 and 3, abuts against a closing stop 56, which is formed on the valve housing 45.
- the closing spring 55 is supported on an opening stop 58, which is also provided on the valve housing 45.
- the valve piston 50 is in the axial direction, ie in Figures 2 and 3 up and down, between the two stops 56 and 58 movable back and forth.
- valve piston 50 closes the pressure reduction opening 44.
- valve piston 50 is shown in its open position. In the open position, the valve piston releases a connection between the inlet opening 46 and the pressure reduction opening 44, so that pressure can be reduced via the pressure reduction opening 44, as indicated by an arrow 59 in FIG.
- the valve piston 50 is electrically actuated by an actuator 60.
- an actuator 60 When the actuator 60 is energized, a force directed downward in FIGS. 2 and 3 is applied to the valve piston 50 by the actuator 60. This force acts counter to the closing force of the closing spring 55.
- the actuator 60 When the actuator 60 is de-energized, then the actuator 60 does not apply force to the valve piston 50. In the de-energized state of the actuator 60, the valve piston 50 is biased by the closing spring 55 in its closed position.
- the pressure reduction valve 42 is closed.
- the closing spring 55 also referred to as a biasing spring, keeps the de-energized pressure reduction valve 42 closed. If the pressure reduction valve 42 is energized, then a force acts on the valve piston 50 via the actuator 60 or a piston rod so that the pressure reduction valve 42 is opened.
- the pressure relief valve 42 is shown in its open position.
- An arrow 59 indicates how pressurized hydraulic medium is discharged from the master cylinder through the inlet opening 46 past the open valve piston 50 through the pressure reduction opening 44 into the reservoir.
- the function of the pressure relief valve 42 can be easily checked.
- a pressure can be built up for diagnostic purposes, which pressure is then discharged through the pressure reduction valve 42.
- the actuator 60 is de-energized for the purpose of diagnosis in order to check whether the pressure in the master cylinder 4 immediately, as it is expected, is reduced via the pressure reduction opening 44.
- this information may be used, for example at system start-up, to generate a "pulse clutch available" signal, and in the event of stalling of the valve piston 50, this may be stored in a fault memory of the controller (2 in FIG Regardless of the diagnostic function that is optional, the pressure relief valve 42 has very little leakage.
- the clutch When an error occurs, that is, when the hydrostatic clutch actuator 3 is defective, because the transmission or the spindle can not move, the clutch should remain in its current position. In particular, the clutch should not be closed further. In such an error case, the master piston 19 is at its necessary for maximum opening of the clutch position. The slave piston 22 is then also at its necessary for the maximum opening of the clutch position.
- the hydraulic medium 7 can be discharged from the master cylinder 4 into the reservoir 17.
- the slave piston 22 is pressed by the restoring force of the plate spring to its minimum position.
- the master piston 19 is still at its maximum position.
- the pressure reduction valve 42 must remain open to 19 in the process of the master piston of the maximum the minimum position - the master cylinder 4 now has to be filled with hydraulic medium - to allow the hydraulic medium exchange with the reservoir 17. If the pressure reduction valve 42 were not opened, a vacuum would occur in the master cylinder 4 or incorrectly air would pass the seals, which is undesirable.
