Definitions
- the invention relates to an actuating device for a clutch of a motor vehicle according to the preamble of the main claim.
- over-center spring is used to reduce the disengaging between the dead center and the disengaged state of the clutch corresponding end position of the clutch pedal lever applied by the driver pedal force.
- over-center spring means that the pedal force to be applied by the driver increases from the end position of the clutch pedal lever corresponding to the engaged state of the clutch to the dead center position of the over-center spring.
- the DE 41 10 476 C2 describes an actuating device for a clutch of a motor vehicle, in which a reduction of the pedal force to be applied by the driver is achieved with additional spring means acting exclusively on the first section of the clutch pedal lever travel between engagement end position and dead center.
- the additional spring means are designed and arranged so that they are only in contact with the end position of the clutch pedal lever corresponding to the engaged state of the clutch up to its dead center position.
- German Auslegeschrift 1 235 153 describes a device for supporting the pedal force for a clutch of a motor vehicle, in which an over the entire Kupplungspedalhebelweg acting Mattertothuiunterst Reifenungsfeder is assigned a switchable according to a certain suspension spring additional spring. This serves to apply an assisting force for the Kochtot Vietnameseunterst Reifenungsfeder in the initial area, since a large force is initially applied in a Belleville spring clutch due to the characteristics of disc springs got to. Thereafter, the additional spring also disengages and the force exerted by the two springs decreases noticeably sharply abruptly.
- the describes DE 36 36 748 C1 an actuator for a clutch of a motor vehicle, in which over the entire Kupplungspedalhebelweg a low actuation force at high contact pressures in the clutch is achieved.
- a compensating spring is used, which acts on the clutch pedal lever, constantly exerts a force on this release towards the end position.
- this force can not be chosen arbitrarily, as over-center spring and clutch pedal lever return spring for a haptic pleasant clutch actuation may not be impaired in their function.
- the object of the invention is to provide an actuating device for a clutch of a motor vehicle, which is characterized haptically pleasant to operate, that applied by the driver on the clutch pedal lever force on the second portion of the Kupplungspedalhebelweges, between dead center and disengagement end position, only to a limited extent decreases.
- the applied maximum force should be low.
- the Tot Vietnamese scopically slidably guided Anschurgien one of which is fixed via a clutch pedal lever fixed bearing and a body-mounted bearing pivotally so that a tensioned between the Anlenk Vietnameseen compression spring as Studentstot Vietnamesefeder the clutch pedal lever depending on its operating position either in the direction of its engagement - Or in the direction of its disengagement position, with intermediate dead center, loaded with force.
- the applied by the driver Clutch actuation force lowered at least over a portion of the clutch actuation path by an additional spring.
- the additional spring lowers the clutch actuation force substantially between the dead center position and an actuation position of the clutch pedal lever, in which the transmissible by the clutch torque can be changed by the driver.
- the invention is characterized in that the auxiliary spring is disengaged in the fully disengaged state of the clutch.
- An advantageous embodiment of the actuator for a clutch is characterized in that the additional spring is also a tensioned between the Anschzhouen compression spring, which is disengaged from the operating position of the clutch pedal lever, in which the transmittable by the clutch torque can be changed by the driver.
- This can advantageously be carried out in a simple manner so that the length of the additional spring is chosen so that it is relaxed from the operating position of the clutch pedal lever, in which the transmissible by the clutch torque can be changed by the driver.
- a further advantageous embodiment of the actuating device for a clutch is characterized in that the Kochtot Vietnamesefeder and the additional spring, coaxially one inside the other, are held between the Anlenk sunnyen.
- the Anlenk spicye of two telescopically slidable tubes can be formed and one of the two springs, Studentstot Vietnamesefeder or additional spring can be kept inside and the other of the two springs outside the tubes, supported by the closed tube ends formed.
- FIG. 1 shows an actuating device for a clutch for a motor vehicle in a side view.
- FIG. 2 shows in a partial section the component for lowering the actuating force and for forming the dead center function, while FIG. 3 illustrates the influence of the pedal force characteristic by the component according to the invention.
- FIG. 1 there is an actuator for a not shown clutch for a motor vehicle from a pivotable about a pivot 10 to a body-mounted bracket 1 clutch pedal lever 5 with an actuator plate 2 for a driver not shown foot.
- the actuator plate 2 is also shown in dashed lines in an operating position 2 '.
- a clutch master cylinder 12 is also attached to the bearing block 1 via first bolts 13, and a piston guided in the clutch master cylinder 12 is connected to the clutch pedal lever 5 via a piston rod 18 by means of a second bolt 17.
- a follow-up line 22 leads from the clutch master cylinder 12 to a not shown liquid expansion tank and a connection piece 23 is a not shown hydraulic line attached. This leads to a not shown clutch slave cylinder whose piston rod actuates the clutch.
- a stop buffer 21 on the bearing block 1 forms an end stop for the clutch pedal lever. 5
- the clutch pedal lever 5 is supported to the bearing block 1 out by a Kochtot Vietnamesefeder 15 a dead center.
- the ends of the Studentstot Vietnamesefeder 15 are received in spring holders 7, 14, which are attached via a third and a fourth pin 20, 16 on the bearing block 1 and the clutch pedal lever 5.
- the spring holder 7, 14, which are telescopically slidably guided into each other, thus forming the Anlenk thoroughlye, one of which via a clutch pedal fixed bearing (fourth pin 16) and one via a body-fixed bearing (third Bolt 20) is pivotally fixed so that the tensioned between the Anlenk Bigen compression spring (Übertot Vietnamesefeder 15) the clutch pedal lever 5 depending on its operating position either in the direction of its engagement (position corresponding actuator plate 2) or in the direction of its disengagement position (position corresponding actuator plate 2 ') applied with intermediate dead center position with force.
- Übertotddlingfeder 15 the clutch pedal lever 5 depending on its operating position either in the direction of its engagement (position corresponding actuator plate 2) or in the direction of its disengagement position (position corresponding actuator plate 2 ') applied with intermediate dead center position with force.
- the clutch actuation force to be applied by the driver is lowered by an additional spring 19 at least over a partial distance of the clutch actuation path.
- Figure 2 shows in a partial section, as the Tot Vietnamese in addition to lowering the clutch operating force substantially between the dead center and an operating position of the clutch pedal lever 5, in which the transferable by the clutch torque can be changed by the driver is formed.
- the additional spring 19 also between the Ansch Bigen (spring holder 7, 14) tensioned compression spring, from the operating position of the clutch pedal lever 5, in which the transmittable by the clutch torque can be changed by the driver, disengaged by the length of the auxiliary spring 19th is chosen so that it is relaxed from this operating position.
- the Studentstot Vietnamesefeder 15 and the auxiliary spring 19 are coaxial with each other, held between the Anlenk Scientificen (spring holder 7, 14).
- the spring holder 7, 14 formed as two telescopically slidable tubes and one of the two springs, the auxiliary spring 19 is within and the other of the two springs, the Mattertot Vietnamesefeder 15, is outside the tubes.
- the falling portion 30 of the force-displacement characteristic of the clutch actuating force becomes flatter between the dead center and the disengaged position.
- the force to be applied by the driver on the clutch pedal lever 5 decreases only to a limited extent on the second section of the clutch pedal lever path, between dead center and disengaging end position, and the clutch is haptically pleasant to operate.
- the applied maximum force 31 is lower and in the fully disengaged state of the clutch, a restoring force reserve 32 is maintained, since the auxiliary spring 19 is disengaged position in this pedal.
