Definitions

  • the invention relates to an actuating device for a clutch of a Motor vehicle according to the preamble of the main claim.
  • DE 41 10 476 C2 describes an actuating device for a clutch a motor vehicle, in which, with additional, exclusively on the first section the Kupplungspedalhebelweges between engagement end position and dead center acting spring means a reduction in the driver applied pedal force is reached.
  • the additional spring means are designed and arranged that they only from the engaged state of the clutch corresponding end position of the clutch pedal lever to its Tot Vietnameselage with this in touching operative connection.
  • DE 36 36 748 C1 describes an actuating device for a Clutch of a motor vehicle, in which over the whole Clutch pedal lever travel a low operating force at high contact forces in the clutch is achieved.
  • the attacking on the clutch pedal lever constantly on this exerts a force towards the release end position.
  • This power can However, not be chosen arbitrarily, because 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 To provide motor vehicle, which is characterized tactile pleasant to operate, that the force to be applied by the driver on the clutch pedal lever, on the second portion of the Kupplungspedalhebelweges, between dead center and disengagement end position, decreases only to a limited extent. In addition, the applied Maximum force to be low.
  • the dead center device exists at least of two in particular telescopically slidably guided into each other Anlenk thoroughlyen, one of which via a clutch pedal lever fixed bearing and a pivoting about a body-fixed bearing is set so that one between the Anlenk thoroughlyen tensioned compression spring as Studentstot Vietnamesefeder the clutch pedal lever depending on its operating position, either in the direction of his Engaging or in the direction of its disengagement, with intermediate dead center, acted upon with force.
  • the applied by the driver Clutch actuation force at least over a portion of the clutch actuation path lowered by an additional spring.
  • the invention is characterized that the auxiliary spring, the clutch actuating force substantially between the dead center position and an actuating position of the clutch pedal lever lowers the torque transmitted by the clutch from the driver can be changed.
  • An advantageous embodiment of the actuator for a clutch is characterized characterized in that the additional spring also a between the Anschzhouen tensioned compression spring is the starting from the operating position of the clutch pedal lever, in the transferable by the clutch torque from the driver can be changed, disengages.
  • This can be beneficial to easy Way be executed so that the length of the additional spring is selected so that this from the operating position of the clutch pedal lever in which the Clutch transmissible torque can be changed by the driver, is relaxed.
  • a further advantageous embodiment of the actuating device for a clutch characterized by the fact that the over-center spring and the auxiliary spring, coaxial with each other, held between the Anlenk thoroughlyen. there can the connecting pieces of two telescopically movable tubes be formed and one of the two springs, over-center spring or auxiliary spring, can inside and the other of the two springs can be outside the tubes, from be kept supported supported the closed pipe ends.
  • FIG. 1 shows a Actuating device for a clutch for a motor vehicle in a side view.
  • FIG. 2 shows a partial section of the component for lowering the Operating force and the formation of the dead center function, while in Figure 3 the Influencing the pedal force characteristic by the device according to the invention is shown.
  • FIG. 1 there is an actuator for a not shown Clutch for a motor vehicle from a via a rotary joint 10 pivotally mounted on a body-mounted bracket 1 clutch pedal lever 5 with an actuator plate 2 for a non-subscribed foot of a Driver.
  • the actuator plate 2 is also dashed in an operating position 2 ' drawn.
  • a clutch master cylinder 12 is also above first pin 13 attached to the bearing block 1 and guided in a clutch master cylinder 12 Piston is connected via a piston rod 18 by means of a second bolt 17 with the Clutch pedal lever 5 connected.
  • a follow-up line 22 leads from the clutch master cylinder 12 to a not shown liquid reservoir and on a connecting piece 23 is a not shown hydraulic line appropriate. 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 spring holder 7, 14, the telescopically displaced into each other are, therefore, form the Anlenk spicye, one of which via a clutch pedal fixed Bearings (fourth bolt 16) and one over a body-fixed bearing (third Bolt 20) is pivotally set so that the between the Anlenk Bigen Tense compression spring (Übertot Vietnamesefeder 15) the clutch pedal lever 5 dependent from 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 ') with intermediate dead center position acted upon with force.
  • Übertotddlingfeder 15 the clutch pedal lever 5 dependent from 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 ') with intermediate dead center position acted upon with force.
  • the clutch operating force to be applied by the driver becomes at least over a portion of the clutch actuation path by an additional spring 19 lowered.
  • Figure 2 shows in a partial section, as the Tot Vietnamese in addition to lowering the clutch operating force substantially between the dead center position and an operating position of the clutch pedal lever 5, in which the transmissible by the clutch torque changed by the driver can be, is trained.
  • the additional spring 19, also a between the Ansch Bigen (spring holder 7, 14) tensioned compression spring, from the Actuating position of the clutch pedal lever 5, in which the through the clutch transmittable torque can be changed by the driver, disengaged, by the length of the additional spring 19 is selected so that this from this Operating position is relaxed.
  • the over-center spring 15 and the auxiliary spring 19 are coaxial into each other, held between the Ansch Scientificen (spring holder 7, 14).
  • spring holder 7, 14 formed as two telescopically slidable tubes and one of the two springs, the auxiliary spring 19, lies inside and the other the two springs, the Mattertot Vietnamesefeder 15, lies outside the tubes.
