Definitions
- the present invention relates to an actuating device for a clutch of a motor vehicle and a motor vehicle with a corresponding Betreli whysvorrich- device.
- Clutches in particular friction clutches, are used in automotive engineering in particular to interrupt a torque flow from a drive motor to a drive train of the motor vehicle.
- releaser for example in the manner of Aus Havenschwingen or Gottausschreibern (CSC - concentric slave cylinder) are known.
- the releasers are mounted in particular in a bell housing and / or the clutches in particular on a flywheel of the drive motor.
- central disengaging devices regularly have a disengaging housing with at least one piston, which can be adjusted relative to the disengaging housing by a hydraulic medium.
- the piston acts in known clutches on disc spring tongues of a plate spring, wherein a pressure plate against a friction lining of the clutch can be pressed by the plate spring, so that a torque of the drive motor via the friction lining on a transmission input shaft of a transmission of the motor vehicle is transferable.
- the plate spring tongues that is, in particular by a deflection of the plate spring tongues by the piston of the releaser, the plate spring releases the friction lining, so that the coupling is opened.
- the clutch is driven by a crankshaft of the drive motor.
- the disadvantage of this is that axial movements of the crankshaft lead to disturbing movements between the diaphragm spring tongues and the release mechanism, which can result in increased wear or even fractures of the diaphragm spring tongues.
- the object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to provide an actuating device for a clutch of a motor vehicle, which has a high wear resistance.
- a clutch for a motor vehicle is to be specified, the actuator is characterized by a high wear resistance.
- the actuating device according to the invention for a clutch of a motor vehicle has a releaser attached to a clutch housing, wherein the releaser comprises a Ausgurergeophuse with a piston which is connected to a pressure plate, wherein upon actuation of the releaser, the Ausschreibergeophuse is adjustable by the piston relative to the clutch housing , so that the pressure plate can be pulled by the release housing against a spring element.
- the actuating device proposed here is used in particular for actuating a clutch of a motor vehicle.
- Such clutches for example in the manner of friction clutches, serve to interrupt a torque flow from a drive motor to a drive train of the motor vehicle.
- the actuator on a fixed to a clutch housing release.
- a releaser may be designed in particular as a slave cylinder for an actuating system.
- Such actuation systems regularly comprise a master cylinder, which is connected via a hydraulic line to the releaser or slave cylinder.
- the clutch housing is used in particular to cover the clutch and can be fastened in particular to a flywheel of the drive motor.
- the release also includes a release housing with a piston.
- the Ausschergephase is in particular annular, so that it can be arranged on a transmission input shaft of a transmission.
- the release housing can be made in several parts.
- the release housing, a first housing part, which in particular comprises the pressure chamber, and a second Housing part with which the releaser is attachable to the coupling housing include.
- the piston is preferably likewise annular and can be adjusted in the release housing, preferably parallel to a longitudinal axis of the release housing.
- the release housing preferably has a pressure chamber for a hydraulic medium, for example hydraulic oil, so that the piston can be adjusted by the hydraulic medium.
- the release housing is connected to a pressure plate for a friction lining of the coupling, so that in particular tensile forces of the release housing on the pressure plate can be transferred.
- the release mechanism housing is adjustable relative to the clutch housing, in particular away from the clutch housing, by the piston, so that the pressure plate can be pulled against a spring element by pulling forces of the release mechanism housing.
- this means that the release mechanism does not act (directly) on the spring element or coupling tongues of the spring element, as is the case with known couplings, but instead a force flow from the release device directly to the pressure plate takes place via the spring element.
- the spring element is in particular at least one plate spring. Under a plate spring is in particular a conical annular shell to understand, which is in particular parallel to the longitudinal axis of the release housing and / or vibratory claimable.
- the spring element serves, in particular, for pressing the pressure plate against the friction lining of the clutch, thereby enabling a torque flow from the drive motor to the drive train or to a transmission input shaft.
- An increase in a pressure of the hydraulic medium in the pressure chamber leads to a movement of the releaser housing and the pressure plate, whereby the pressure plate pushes together the spring element, so that the friction lining of the clutch is releasable.
- the torque flow is interrupted by the drive motor to the drive train of the motor vehicle and it can be switched.
- the piston or a first housing part of the releaser housing can be decoupled via a first bearing from a rotation of the coupling housing.
- the first bearing is a roller bearing, thrust bearing, thrust ball bearings or thrust roller bearings.
- the first housing part of the release housing can be arranged in particular rotationally fixed on a transmission input shaft of the motor vehicle, when the clutch housing rotates in particular about a longitudinal axis.
- the first bearing is arranged between the first housing part and a second housing part of the releaser housing, wherein the second housing part is fastened to the coupling housing.
- the second housing part of the release housing with the clutch housing in particular rotate about a longitudinal axis, wherein the first housing part is simultaneously rotatably on the transmission input shaft can be arranged.
- the piston or a first housing part can be decoupled via a second bearing from a rotation of the pressure plate.
- the second bearing may be, for example, a roller bearing, thrust bearing, axial ball bearing or thrust roller bearings.
- the second housing part of the Ausgurerge- housing can be decoupled from the rotation of the pressure plate.
- the Ausschergeophuse is connected via a pulling element with the pressure plate.
- the drawing element is in particular an at least partially tubular element, with the tensile forces of the first housing part can be transferred to the pressure plate.
- the drawing element can have at least one radially extending region, by means of which a positive connection between the drawing element and the pressure plate can be produced.
- the release housing can be connected to a rotary lock.
- the Ausrückergepatuse in particular a radially extending tab, with the Dreharret ist, for example via a
- Screw connection is connectable. As a result, the release housing can be secured against rotation on the transmission input shaft.
- the spring element comprises a plurality of disc springs.
- the plurality of disc springs is stacked in particular in the axial direction. This allows an increase in the wear reserve.
- a clutch for a motor vehicle with an actuating device according to the invention is also proposed.
- FIGS. show, but are not limited to, particularly preferred variants of the invention.
- the same components are provided in the figures with the same reference numerals.
- 1 shows a first variant of an actuating device in a partial longitudinal section
- 2 shows the first variant of the actuating device in an end view
- FIG. 3 shows a second variant of the actuating device in a partial longitudinal section.
