Definitions
- Actuation system in particular for actuating a clutch
- the invention relates to an actuating system, in particular ur actuation of a clutch of a motor vehicle is used.
- Known engagement systems consist of an engagement lever and an engagement bearing. Oa the engagement lever makes a pivoting movement during engagement, the bearing with a netn hinge is connected to the lever. So soft to ensure that the bearing can align parallel to the clutch. Due to the pivoting movement of the lever, however, a radial force is generated during the Eängurvorgang, which acts on the joint. This creates a tilting moment on the bearing, which tilts the bearing. This skew occurs even with centric force. In order to minimize the tilt, there is often a radial out- er under the bearing. This slides during the engagement process. This is to compensate for the misalignment,
- Clutches also always contain geometrical errors (e.g., paralysis errors) in their components due to manufacturing punching, thereby inducing unwanted off-axis effects in the drive train, which manifests itself in noticeable driver vibration during startup, so-called juddering vibrations.
- geometrical errors e.g., paralysis errors
- an actuating system for a clutch with a lever actuator which comprises a lever having an actuator region in which an actuator force is applied to the lever by an actuator; a support area in which the lifting! is supported; and a force application region disposed between the actuator overtravel and the support region, via which an actuation force is applied to the torque transmission.
- German Offenlegungsschrift DE 10 2010 054 301 A1 discloses an actuation system in which an engagement lever is pivotally supported on a support body. At an operating end of the engagement lever engages an Betschistskotben with which a clutch is actuated via the engagement lever. The actuating force or actuator force acts in an axial direction substantially perpendicular to the engagement lever.
- a disadvantage of the known solutions is that due to friction in Radiaiausgieich and the error combination of the clutch disc to engagement system ⁇ geometric parallel lltfeer ⁇ the camp never paralie! to the coupling plane. There is always a skewed position of the camp recorded, which can lead to a Rupfanregung in the vehicle.
- the object of the invention is to develop an actuating system for a clutch, with the without additional components or further cost skewing the
- Actuating system is used in particular for actuating a clutch of a motor vehicle and has a pivotable when actuated about a pivot axis of a Geienks operating lever with which acting on a clutch rotation axis clutch engaging Ein Wegiager is actuated, according to the invention by an axial offset between the pivot axis of the joint on Actuating lever and the coupling axis of rotation in the Ein Wegiager a skewing of the bearing compensating overturning moment can be introduced such that it acts opposite to a tilting moment soft caused by the actuation of Betrelirsheabeis.
- the Einschiager acts known to be on lever spring tongues (Telierfederzept) of the clutch, which abut in a Hebelelfonnezonneieräage Einschreibiager, the required axial offset is determined in dependence on a coefficient of friction in a Radiaiausgieich between the Einschreibiager and the Einschreibiager receiving bearing carrier and a height between the HebeSfederzonneschreiblage and Radiaioglu according to the formula
- the Einschiager is connected to a hinge on the actuating lever, so that the Einschiager aligns parallel to the coupling and between the Einschiager and the Arranged hinge of the bearing carrier, so that between the bearing carrier and the Einschreibiager a radial compensation is present such that between the bearing yield and the bearing a sliding movement upon actuation of the bearing can be realized.
- Figure 1 shows the schematic representation of the operating lever and Einröcklager according to the prior
- Figure 2 di schematic diagram of actuating lever! and Einguriager according to the state of
- FIG. 3 shows the principle of division of the actuating lever and the engagement follower with axial offset in an open clutch
- FIGS. 1 and 2 show the principle of division of the engagement kinematics according to the prior art and in FIGS. 3 and 4 according to the solution according to the invention.
- An actuating lever 1 (engaging lever) is pivotally mounted and actuated at a first end of a plunger 2 tete and received at a second end to a counter bearing 3. Since the engaging lever 1 performs a pivoting movement during Einröckens, a Einguriager 6 receiving bearing support 5 is operatively connected via a hinge 4 with the Hebei. So it should be ensured that the Einschreibiager 6 with its Betuschistsflä- 6.1 parallel to a coupling plane E of the coupling, indicated here by the lever spring tongues? (Plate spring tongues), can align.
- the joint 4 has a pivot axis A4 and the coupling has a coupling axis of rotation A7.
- the actuating surface 6.1 of the engagement trimmer 6 in the disengaged state is essential. aligned parallel to the coupling plane E of the coupling Due to the pivoting movement of the lever 2 when it is actuated with the bumps! 2 arises during the engagement process, a radial force FR, which acts on the joint 4 (see Figure 2). This radial force generates a tilting moment fvIK on the engagement bearing 6, causing it to tilt undesirably. This skew division also occurs with centric force application.
- the necessary axial offset X is dependent on the coefficient of friction ⁇ in the radial compensation R and the height H between the lever spring tongue support, which corresponds to the actuating surface 6.1, and radial outlet R.
- the engagement system is improved, so that geometric Paralielititsfehier be limited and the error Einschsysiem is minimized. It is just engaged and for the driver unpleasant Jupiter vibrations avoided. The driving comfort for the driver and thus the customer satisfaction increases. This improvement is possible without additional components or additional costs.
