Definitions
- the present invention relates to an actuating mechanism for a clutch actuator and to a clutch actuator with such a device
- Actuating mechanisms convert an actuating force which on a
- Actuator is applied in a shift of a
- Transmission element to, for example, disengage a clutch by introducing the displacement into the clutch.
- other technical devices can also be actuated by means of such an actuation mechanism.
- an actuating mechanism for a clutch actuator comprising:
- an actuating element which is designed to be acted upon by an actuating force and which is designed to be displaceable parallel to the actuating direction
- the actuating element is arranged and which is designed to increase a contact force between the wedge element and the transmission element when the actuating element is acted upon by an actuating force so that the actuating force can be transmitted to the transmission element so that the transmission element can be shifted in the actuating direction, in which
- the actuating mechanism is designed, when no actuating force acts on the actuating element, to reduce the contact pressure between the transmission element and the wedge element in such a way that a relative movement of the
- the actuation mechanism is preferably designed so that the actuation force is transmitted from the actuation element to the wedge element. This can be done directly or via elements arranged between the wedge element and the actuating element.
- the transmission element is designed to operate a clutch, that is, to disengage and engage the clutch, the relative movement of the transmission element can preferably be used to readjust a wear path within the clutch.
- the contact pressure between the transmission element and the wedge element is preferably so high that a force fit is formed, the maximum force that can be transmitted corresponds to at least the amount of the actuation force.
- the frictional connection thus preferably creates a clamping between the transmission element and the wedge element.
- the actuating element When the actuating force is applied to the actuating element, the actuating element, the wedge element, the counter element and the transmission element are preferably blocked. I.e. these elements of the
- Actuating mechanisms are now shifted by the actuating force as a block, i.e. as a unit, in the actuating direction.
- the transmission element is preferably designed as a rod which has an axis that extends parallel to the actuation direction, the rod particularly preferably having a circular cross section. In this way, an arrangement of several wedge elements around the transmission element is possible. In addition, however, other cross-sectional shapes, such as a
- the wedge element preferably has a support surface which is not oriented parallel and not perpendicular to the actuation direction or the axis of the transmission element.
- the support surface is preferably designed to generate the pressing force or the clamping when the actuating force is supported.
- the support surface is preferably designed so that the actuating force on the
- Support surface is transmitted, whereby, by the orientation of the support surface to the actuation direction or the axis of the transmission element, a
- the actuation force is preferably oriented parallel to the actuation direction.
- the support surface is preferably designed as part of a conical surface which extends around the direction of actuation or around the axis of the transmission element extends.
- the support surface can also have a different shape.
- the support surface is designed as a plane that leads to the
- the direction of actuation or the axis of the transmission element preferably form an angle greater than 0 ° and less than 90 ° with the support surface.
- This angle is preferably between 5 ° and 45 °, particularly preferably between 10 ° and 35 °. In the case of a support surface which is designed as part of a conical surface, this angle corresponds to half the opening angle of the cone. If the support surface is designed as a plane, this angle corresponds to an angle of inclination of the plane with respect to a horizontally extending plane.
- the support surface is preferably designed to act when the
- Actuating element to come into contact with the actuating force with a correspondence surface, via which the actuating force can be transmitted, wherein the correspondence surface is formed on a counter element.
- the contact between the support surface and the corresponding surface is preferably achieved that the introduced into the actuating mechanism
- Operating force is at least partially deflected into a pressing force between the wedge element and the transmission element. In this way, clamping preferably begins when the actuating force is sufficiently high.
- the correspondence surface is preferably designed as a rotationally symmetrical surface around the direction of actuation or around the axis of the transmission element.
- the correspondence surface is preferably designed such that the support surface of the wedge element can come into contact over the entire surface with at least part of the correspondence surface.
- the correspondence surface and / or the support surface are preferably designed at least as part of a conical surface or as a plane.
- the correspondence surface preferably forms the same angle with the
- At least one further wedge element is preferably provided.
- the wedge elements are preferably arranged at a distance from one another around the actuating direction or around the axis of the actuating element, the wedge elements particularly preferably being arranged regularly spaced from one another around the actuating direction or around the axis of the actuating element.
- each wedge element is particularly preferably guided in its own groove. So the wedge elements are spaced from one another.
- the grooves can preferably be formed on the transmission element.
- Another possibility of realizing a spacing consists in the formation of guides which extend parallel to the direction of actuation and which only give the wedge elements a possibility of movement parallel to the direction of actuation.
- the guides can be used separately or on any element of the
- Actuating mechanism in particular on the actuating element or the
- the spacing can also take place by means of a cage which contains the wedge elements and is designed to spac them apart from one another.
- the cage extends around the direction of actuation and allows the wedge elements to be displaced parallel to the direction of actuation. Furthermore, the cage also allows the transmission element to be displaced parallel to the actuation direction if no actuation force is applied to the actuation element.
- the actuation direction is preferably designed as a straight line.
- a stop is provided which is designed to with the
- the stop is preferably positioned so that a contact force between the support surface of the wedge element and the
- Correspondence surface of the counter element is reduced or completely eliminated when the wedge element and the counter element move opposite to the actuation direction and when the wedge element or the counter element rest against the stop. This is achieved in that the element, that is to say the wedge element or the counter-element, which rests against the stop, no longer goes against the
- Operating direction can be shifted while the other element, that is, the counter element or the wedge element, which does not bear against the stop, is moved further against the operating direction.
- the actuating mechanism is preferably designed so that a clamping between the wedge element and the transmission element is brought about by the pressing force between the wedge element and the transmission element.
- the actuating mechanism is preferably designed to bring about the pressing force between the wedge element and the counter-element in response to the application of the actuating force to the actuating element.
- the actuating mechanism is preferably designed so that when the contact force is reduced, for example by reducing the actuating force or because one of the elements is supported on the stop, the contact pressure between the transmission element and the wedge element is also reduced, so that at sufficient reduction finally the clamping is released, and that a relative movement of the transmission element relative to the wedge element and relative to the actuating element is made possible.
- the relative movement can thereby take place with contact of the transmission element with the wedge element, or completely without contact.
- actuating mechanism is used for a clutch actuator, a possible wear path can be compensated for when the clutch is engaged.
- the contact between the support surface and the corresponding surface also already exists before the actuation force is applied, with this preferably not causing any clamping between the wedge element and the transmission element.
- the actuating mechanism is designed to
- Actuating element, the wedge element and / or the counter element with an elastic biasing force against the direction of actuation, so that
- Actuation direction takes place, wherein the elastic preload force is preferably caused by a spring.
- This elastic pre-tensioning force preferably results in tensioning of the corresponding elements.
- the actuation mechanism is further preferably designed so that the elastic preload force counteracts the actuation force.
- the elastic pre-tensioning force enables a return movement of the interlocked elements of the actuation mechanism to occur as soon as the actuation force is reduced or no longer applies.
- the actuating mechanism is further preferably designed to have an elastic biasing force, preferably with an effective direction parallel to the
- This elastic pretensioning force is preferably produced by a spring.
- the pretensioning force can either be designed to brace the wedge element and the counter-element against one another, so that the spring force eliminates any possible play between the support surface and the corresponding surface. This causes an increase in the contact force between the wedge element and the Counter element. In this way, in particular, the initial clamping between the wedge element and the transmission element can be improved, so that the individual elements can be quickly blocked when an actuating force is applied.
- the biasing force is designed to the wedge element and the
- Actuating force acts on the actuating element. This causes a reduction in the contact force between the wedge element and the counter element. As a result, the initial clamping between the wedge element and the
- Transmission element can be reduced, so that when an actuating force is no longer required, the individual elements can be quickly released.
- the transmission element is preferably acted upon by an elastic prestressing force in the actuating direction, which is preferably caused by a spring.
- This spring is also preferably based on one opposite the
- Transmission element fixed point such as a housing of the
- Transmission element if no actuating force is applied to the actuating element, a force is always applied in the actuating direction, so that the transmission element always has a corresponding element to it
- Shifting it is designed to stay in contact.
- the actuating element is preferably designed to be acted upon by a fluidic actuating force, the actuating element preferably being designed as a piston, particularly preferably as an annular piston, which further
- a fluidic actuation force is to be understood in particular as a pneumatically generated actuation force, alternatively also a hydraulically generated one
- the actuating element is also designed to be acted upon by a mechanically, electrically or electromechanically generated actuating force.
- a linkage can preferably be provided which is designed to apply the actuation force to the actuation element by preferably transmitting a displacement to the actuation element via the linkage.
- actuation means are preferably provided in order to apply the actuation force to the actuation element.
- An electric motor, a linear motor or a magnetic mechanism, for example, can be provided as the actuation means.
- the actuating element can only be designed to absorb the actuating force and to support it on the other elements, such as the counter element or the wedge element.

- a clutch actuator is also provided, the one
- Actuating mechanism is preferably designed to use the
- Transfer element to come into contact with a corresponding element of the clutch in order to disengage it.
- the clutch is disengaged when the
- Transmission element is moved in the actuating direction and thus moves the corresponding element of the clutch.
- the clutch has a clutch spring which is designed to have a
- the transmission element is preferably acted upon by an elastic biasing force in the actuating direction, which is preferably caused by a spring.
- the elastic pretensioning force has the effect that the transmission element remains in contact with the corresponding point of the coupling. If no actuating force acts on the actuating element, the transmission element can be parallel to the actuating element relative to the
- the forces of the clutch spring and the elastic preload force now act against one another via the transmission element.
