Definitions
- the invention relates to a method for reducing a release force of a plate spring an automated clutch, which is manually operated, wherein a gear is automatically inserted.
- a coupling system which comprises a plate spring, which braces a pressure plate with the pressure plate.
- a plate spring which braces a pressure plate with the pressure plate.
- clutch-by-wire clutch systems are increasingly being used, which represent automated clutch systems in which the clutch is adjusted by hand, but the engagement of the associated gear takes place automatically. In such a manual transmission, the clutch can always be fully opened or closed. Therefore, the minimum of the disengagement force of the clutch must be designed so that even at maximum engine speed of the drive motor of the vehicle and all conceivable tolerances, the disengagement force of the clutch is greater than 0 N, so that the plate spring, which presses the pressure plate against the clutch disc, when coupling returns to its original position.
- a minimum of the disengagement of the plate spring must always be positive, no matter what speed of the engine is set.
- the disadvantage here is that the release force of the clutch and the force acting on the diaphragm spring centrifugal force change depending on the speed due to this characteristic. Due to a characteristic change of the plate spring, which is due to the effect of the speed, the Ausgurkraft-minimum is significantly reduced. This has the disadvantage that when operating the clutch by a clutch pedal by the driver much more force must be expended.
- the invention has for its object to provide a method for reducing a release force of a plate spring an automated clutch, in which the pedal force to be applied by the driver is reduced.
- the object is achieved in that at a minimum of the Ausschkraft the diaphragm spring smaller than 0 N via a control parameter of the clutch, the setting of a negative disengagement of the plate spring in active operation of the clutch is suppressed.
- the characteristic of the plate spring is always set so that only a slight force is spent in the pedal operation by the driver. Should it be used areas of the characteristic of the diaphragm spring, which cause a false reaction in the operation of the diaphragm spring and thus also the clutch, this is monitored by the control parameters and actively prevented.
- the disengagement force of the disc spring is set as a function of a rotational speed of the internal combustion engine used as a control parameter.
- the relationship is used, which exists between the Aus Wegkraftkennline the plate spring and the speed of the engine.
- the characteristic of the plate spring is designed so that the lower the minimum of the disengagement of the plate spring, the more Aus Wegreduzi für is possible in the maximum of the characteristic of the plate spring.
- the clutch actuation occurs at a speed that is less than a predetermined limit speed, over the entire disengagement of the clutch. It is assumed that the characteristic of the diaphragm spring is documented in positive disengaging forces over the complete disengagement travel of the clutch.
- the clutch actuation takes place at a speed which is greater than the predetermined limit speed only up to a defined disengaging point. This prevents the risk of missing restoring forces.
- FIG. 2 is a schematic representation of a part of a friction clutch in a closed torque-transmitting state
- Fig. 3 shows an embodiment of the characteristic of the diaphragm spring according to the prior art.
- Clutch systems in the form of clutch-by-wire systems are frequently used in motor vehicles.
- a clutch-by-wire system is an automated clutch in which the clutch is manually operated by means of a clutch pedal, not shown, while the gear to be engaged is automatically shifted.
- the Ausgurweg the clutch is operated only up to a disengaging point or shortly thereafter in normal driving.
- the minimum of Ausgurkraftkennline the diaphragm spring which is shown in Fig. 1, designed significantly lower.
- the design can be made to a significantly lower minimum, which is shown in the curves A, B, which move in the negative region of the release force and thus allow no restoring forces of the diaphragm spring.
- the curve A corresponds to a speed of the internal combustion engine of 6000 revolutions per minute
- the curve B shows a speed of the internal combustion engine of 4000 revolutions per minute.
- the characteristics of the diaphragm spring at speeds of the internal combustion engine of 2000 revolutions per minute (curve C) or at 0 revolutions per minute (curve D) are completely in the positive range.
- FIG. 2 is a schematic representation of a portion of a friction clutch 1 is shown in a closed, torque-transmitting state, as used in motor vehicles application.
- a friction clutch 1 has a clutch cover 2 and a counter-pressure plate 3.
- the clutch cover 2 is fixedly connected to the counterpressure plate 3 by means of screws.
- the friction clutch 1 is configured to rotate about the rotation axis 5.
- the friction clutch 1 has a rotatably and axially limited to the clutch cover 2 displaceably arranged pressure plate 6, of a bearing on the clutch cover 2 pivot bearing 4 with respect to the housing fixedly arranged counter-pressure plate 3 under tension of friction linings 8, 9 a clutch disc 7 for opening and closing the Friction clutch 1 in the axial direction 10 is displaced.
- the pivot bearing 4 has a anpressplatten workedes bearing 1 1, a cover-side bearing 12, the pin 13 and a lever member 14 of the plate spring, not shown.
- an adjusting ring 19 is arranged between the lever element 14 of the plate spring and the pressure plate 6, which is rotated by a spindle drive 15 when the closure is detected.
- a form-fit is produced if, as a result of the wear, an extended travel of the pressure plate 6 with respect to the clutch cover 2 results.
- the pinion 16 has a plurality of sawtooth-shaped teeth, namely a saw toothing 20.
- a tooth length 21 of the pinion 16 is made larger than a minimum lift 22, which is necessary for separating the clutch disc 7.
- the drive pawl 17 is arranged at least partially cover-fixed on the clutch cover 2.
- the drive pawl 17 is connected through a window 18 on an outside of the coupling led lungsdeckels 2 and fastened by means of the bolt 13 on the clutch cover 2.
- the bolt 13 is guided by the lever element 14 of the diaphragm spring, the clutch cover 2 and a partial region of the drive pawl 17.
- the drive pawl 17 then snaps positively into the saw teeth 20 when the friction clutch 1 is closed and takes on the pinion 16 when the friction clutch 1 is opened. Following this, the drive pawl 17 slides back out of the saw teeth 20 of the pinion 16 and a first adjustment cycle is completed. Such a coupling process is triggered by a clutch-by-wire system.
