Definitions
- the invention relates to a method for protecting a clutch actuator of a clutch actuation system, preferably for a motor vehicle, which activates a self-closing clutch by a first piston of a master cylinder of the Kupplungsaktorik is adjusted by an electric motor, whereby a hydrostatic path for actuating the clutch, a second piston of a Slave cylinder is moved and a maximum travel of the second piston is limited by a stop.
- a method for driving a clutch with a Hydrostataktor which comprises a threaded spindle which is rotated to move a piston of a master cylinder in the axial direction, wherein a distance traveled by the piston path by means of a Sensor device is determined directly or indirectly.
- the clutch is actuated via a hydrostatic circuit.
- the piston of a master cylinder is driven by an electric motor and actuated via a hydraulic fluid in the system, a second piston in a slave cylinder.
- the second piston of the slave cylinder acts on the lever spring tips, which then lifts on actuation of a clutch plate of a clutch disc and thus interrupts the transmission of a clutch torque via the clutch.
- the preloaded lever spring closes the clutch.
- Coupling actor occur, such as piston area tolerances, friction scattering, absolute value sensor error of the hydrostatic actuator, new state and others, a certain way the hydrostatic clutch actuator (HCA) are approached.
- HCA hydrostatic clutch actuator
- Clutch actuator (HCA) of 13.3 mm are approached. However, if the hydrostatic clutch actuator (HCA) retards a distance of 13.3 mm, an adjustment distance in the slave cylinder can amount to 10.8 mm. Due to space constraints, however, the maximum stroke of the slave cylinder is limited to 9.6 mm. However, in order to move the clutch into the safe opening position, the maximum permitted limit is given by the way of the hydraulic clutch actuator (HCA) due to the tolerance spread
- the invention has for its object to provide a method for protecting the
- this object is achieved in that a non-permanent stop is used, wherein the stop is considered to be operated when the second piston of the slave cylinder has covered a Anschlagungsweg, which is reduced by a predetermined distance from the stop, depending on the traveled stroke a maximum position of a hydrostatic clutch actuator is defined.
- a stop which is not designed for the entire life of the slave cylinder. This ensures that the stop in the slave cylinder is not actuated by most systems that include the clutch and the hydrostatic clutch actuator. Due to the lack of operation is reliably prevented that the slave cylinder is damaged.
- Clutch actuator in response to the non-fatigue stop ensures that in this position of the slave cylinder, the clutch is securely opened and thus no clutch torque is transmitted.
- the clutch actuator is actuated until a successful detection of the stroke of the second piston, wherein upon successful detection of the stop travel of the second piston, a first position of the hydrostatic
- Clutch actuator which is smaller than the maximum position, is considered reached, in which the clutch is securely opened. Since in this case the maximum position of the hydrostatic clutch actuator is certainly not approached, thus eliminating forces that operate the slave cylinder over the predetermined maximum stroke and thus destroy the system.
- the maximum position of the hydrostatic clutch actuator is reduced by a predetermined value in the absence of detection of the stop travel of the second piston of the slave cylinder. This ensures that the clutch is always safely opened due to the position assumed by the hydrostatic clutch actuator and that the maximum lift of the slave cylinder is not exceeded.
- the determination of the maximum position of the hydrostatic clutch actuator in dependence on tolerances of a the stop travel of the second piston of the slave cylinder detecting displacement sensor.
- the tolerances of the individual system units are taken into account, but at the same time those of the measuring sensors, so that an erroneous operation of the clutch actuator is reliably prevented.
- a touch point adaptation is performed as part of the tape end test, wherein a standby point of the hydrostatic
- Clutch actuator is defined, in which the clutch is considered open. Due to this setting, the routines that are performed during the tape end check can be processed reliably.
- the readiness point of the hydrostatic clutch actuator is smaller than its maximum position.
- the standby point which represents the touch point plus a tolerance of x mm, indicates that the clutch is defined as open for further operation. Since this touch point and thus the standby point represents an important parameter in the control of the clutch during operation of the motor vehicle, this must not be above the maximum position of the hydrostatic clutch actuator to prevent damage to the Kupplungsaktorik.
- a clutch of a drive train of a hybrid vehicle is used as a clutch. In this case, errors that can be transmitted during the positioning of the hydrostatic clutch actuator on the piston of the slave cylinder, minimized.
- FIG. 1 Schematic representation of a clutch actuation system in the hybrid vehicle, a representation of the translation spread of a clutch with a hydrostatic clutch actuator according to the prior art.
- the schematic diagram of a drive train 1 of a hybrid vehicle is shown in FIG. 1.
- This drive train 1 comprises an internal combustion engine 2 and an electric motor 3. Between the internal combustion engine 2 and the electric motor 3, a separating clutch 4 is arranged directly behind the internal combustion engine 2. Internal combustion engine 2 and separating clutch 4 are connected to each other via a crankshaft 5.
- the electric motor 3 has a rotatable rotor 6 and a fixed stator 7.
- the output shaft 8 of the separating clutch 4 is connected to a transmission 9, which contains a coupling element, not further illustrated, for example a second clutch or a torque converter, which is arranged between the electric motor 3 and the transmission 9.
- the transmission 9 transmits the torque generated by the internal combustion engine 2 and / or the electric motor 3 to the drive wheels 10 of the hybrid vehicle.
- the separating clutch 4 and the transmission 9 in this case form a transmission system 1 1, wherein the separating clutch 4 is driven by a hydrostatic clutch actuator 12.
- the hydrostatic clutch actuator 12 is shown simplified for actuating the separating clutch 4.
- the hydrostatic clutch actuator 12 comprises a master cylinder 13, which is connected via a designated also as a pressure line hydraulic line 14 with a slave cylinder 15.
- a slave piston 16 is mounted axially movable, which actuates the separating clutch 4 with the interposition of a release bearing 17.
- a master piston 18 is mounted axially movable. From the master piston 18, a piston rod 19 goes out, which is translationally movable in the longitudinal extension of the master cylinder 13 together with the master piston 18.
- the piston rod 18 of the master cylinder 13 is coupled via a threaded spindle 20 with an electromotive actuator 21.
- the electromotive actuator 21 includes an electric motor 22 and an evaluation unit 23.
- the threaded spindle 20 sets a rotational movement of the electric motor 22 in a longitudinal movement of the piston rod 19 and the master piston 18 to.
- Parallel to the master cylinder 13 a first displacement sensor 24 is arranged, while a second displacement sensor 25 detects the displacement of the slave piston 16 on the slave cylinder 15.
- the disconnect clutch 4 is an unconfirmed closed clutch (self-closing clutch).
- the clutch 4 comprehensive transmission system 1 the transmission system 1 1 subjected to a tape end test on which stops for both the slave piston 16 of the slave cylinder 15 and ways that the hydrostatic clutch actuator 12 is allowed to travel maximum learned to thus to prevent a destruction of the clutch actuator.
- an actuating stroke is carried out on a test stand on the tested transmission system 1 1, wherein the hydrostatic clutch actuator 12 assumes a predetermined position by the movement of the master piston 18 of the master cylinder 13, which is transmitted via the hydraulic fluid to the slave piston 16 of the slave cylinder 15, this also occupies a corresponding position.
- the stop travel of the slave piston 16 of the slave cylinder 15 to be detected is adjusted such that the stop is considered to be reached when a predetermined distance value, by which the stop position is reduced, is reached by the second slave piston 16 of the slave cylinder 15 , which is detected by way sensor 25.
- this predetermined distance value is successfully detected by the displacement sensor 25 when the transmission system 21 is actuated, it is assumed that the state of the separating clutch 4 is ensured to be safely opened with this actuating stroke.
- the master cylinder 13 of the hydrostatic clutch actuator 12 assumes a position in which the separating clutch 4 is reliably opened by the slave cylinder 15 without damaging it.
- the impact forces and the plate spring travel, which actuate the separating clutch 4 lie within predetermined tolerances.
- a minimum distance value for a safely opened disconnect clutch 4 for example, 1 mm, which means that the stop travel to be detected, which the second slave piston 16 of the slave cylinder 15 covers during an actuating stroke, 1 mm before the actual mechanical Stop ends.
- the tolerances of the displacement sensor 24 are also taken into account, which detects the path of the master piston 18 of the master cylinder 13.
- This maximum position corresponds to a stroke of the slave cylinder 15, which is 0.5 mm smaller than the position of the stop of the slave cylinder 15. This ensures that the self-closing clutch 4 opens sufficiently at this defined path of the hydrostatic Kupplungaktors 12 so that the band end Routines can be performed.
- the stop of the slave piston can be approached once during a new startup, for example in the case of servicing a component replacement.
- the second possibility of setting maximum positions of the hydrostatic clutch actuator 12 and the stopper is considered on the premise that the slave piston 16 of the slave cylinder 15 has not executed the defined stop travel, which therefore can not be detected. It is assumed that the impact forces are in order, but not the cup spring travel. In this case, each transmission system 12 is subjected to an operating stroke on the test bench, in which it is assumed that the hydrostatic clutch actuator 12 safely opens the disconnect clutch 4 plus a defined additional travel, which in turn takes into account the tolerances of the travel sensor 24. In transmission systems 21, which do not cover the predetermined stroke, the maximum position of the hydrostatic clutch actuator 12 is limited to the driven stroke by 0.5 mm.
- the separating clutch 4 is in each case sufficiently actuated, which is why the requirement of the stop and the permitted disc spring travel are taken into account.
- the maximum position of the hydrostatic clutch actuator 12 is now learned as well as the stop and is stored in the transmission system 21 and used when starting the clutch 4 during operation in the motor vehicle, with damage or destruction of Kupplungsaktorik Over the life of the operation of the slave cylinder 16 is reliably prevented.
- a touch point adaptation is carried out during the end-of-line test in which a standby point is defined as a function of the detected touch point at which the disconnect clutch 4 begins to transmit a clutch torque in which the separating clutch 4 is reliably open and thus transmits no clutch torque.
- the standby point is composed of the touch point plus x mm.
