Description

[0001] EXTRUSION PRESS [0002]

The present invention relates to an extrusion processing machine.

Extrusion machines of this type are known, for example, from EP 0 379 937 A2 and are used to press metal billets through a die. To this end, the extrusion machine generally comprises a die, a billet vessel for receiving and holding the billet to be extruded during extrusion such that the billet can only be discharged through the die, and an extrusion ram which can be displaced relative to the billet vessel and die, A pressing force, which is normally introduced into the extrusion machine by the main cylinder, which is preferably a plunger cylinder, can be applied through the extrusion ram. A frame comprising at least one cylinder beam and an opposing beam interconnected by a prestressed tie rod is used as a press frame in the general case and the die is provided on the cylinder beam and the opposing beam of the main cylinder . The tie rods generally include an effective tension member between the cylinder beam and the opposing beam and effective pressure pieces between the cylinder beam and the opposing beam.

Wherein the extrusion ram is relatively extruded toward the die and is directly extruded through the billet container during extrusion; indirect extrusion processing in which the die is placed on a dummy ram through the billet container during extrusion; and also a special process such as hydrostatic extrusion . A less common embodiment of such an extrusion machine, such as a continuous extrusion machine, includes elongated extrusion rams and also dia rams. It is clear that even in the case of continuous extrusion machines, the die itself can be displaced relative to the frame during extrusion. If necessary, for example, the displacement of the extrusion ram can be eliminated if all movements are reversible. Likewise, the extrusion ram and also the die can of course be axially displaced. This is applied to a billet container, which can be a structure which is axially displaceable relative to the die and / or extrusion ram, in particular for loading, and, in some cases, axially displaced relative to the frame, It may follow.

The assemblies and possibly also other assemblies undergoing loads during extrusion, which are therefore induced by forces and moments generated by extrusion, such as billet containers, dies or other extrusion rams, When it can be displaced relative to the guide. This need not necessarily be the case, but may also occur indirectly through corresponding assemblies that in turn support such assemblies. Thus, a container holder that holds the billet container and is guided on the frame is generally provided. Likewise, the extrusion ram is typically placed on a container holder, which in turn is guided over the frame. So that corresponding mounts or beams may be provided in the case of other assemblies or dies guided accordingly.

The guide often comprises a guide device and two guide devices are generally provided on both sides of each assembly or three or more guide devices and possibly also a plurality of such guide devices are provided so that corresponding moments are also suitable . This type of guide device generally includes an assembly side guide component disposed on a corresponding assembly via a guide component carrier provided on a corresponding assembly, which guide component carrier is also optionally integrated with the assembly to be guided . In order to compensate for this, the guide device also includes a frame-side guide part that interacts with the assembly-side guide part in a guiding manner and is fixed to the frame. In particular, sliding blocks, sliding shoes, and corresponding bearings are also used in this case as assembly-side guide parts, with correspondingly complementary guide rails being generally used as frame-side guide parts. It will be apparent that specific embodiments of this type may be provided as well, if desired.

Also, this type of assembly, which undergoes a load during extrusion induced by forces and moments generated by extrusion, is often motor-driven by a powered drive device, and in this case in accordance with a specific embodiment, A motor or a hydraulic drive device is used. In such a case, the power-driven drive may be associated with an assembly-side drive position disposed on a drive-position carrier on each of the cases corresponding to the case, the drive-position carrier being optionally constructed as a unit with the crossbeam or container holder Or be integrated with the assembly to be driven or driven. Specifically, for example, a motor-power drive pinion and a rack gear to which the drive pinion is coupled can be used for a drive device that is powered. It is clear that a plurality of drive pinions of this type may be combined with an assembly displaced from the other side, in particular so as to avoid an excessive tilting moment present during drive through such a motorized drive.

The problem addressed by the present invention is to minimize the effects of moment and force generated by extrusion on other parts of the extrusion machine.

The problem addressed by the present invention is solved by an extrusion machine having the features of the independent claim. Possibly other advantageous embodiments thereof, can be found in the dependent claims and the following detailed description.

The present invention is based on the fact that the effects of the moment and force generated by the extrusion on other parts of the extrusion machine are intercepted through their interactions between the assemblies as far as possible, Based on the basic knowledge that a certain clearance is allowed for the assembled assembly, but can be minimized by maintaining the most accurate guidance.

By implementing this basic idea in concrete terms, the influence of the moment and force generated by the extrusion on other parts of the extrusion machine can be further enhanced by the use of a billet vessel and a billet vessel, and an extrusion ram displaceable relative to the die, An extrusion processing machine for extruding, wherein at least one assembly of an extrusion processing machine subjected to a load during extrusion induced by a force and a moment generated by extrusion is displaceably guided along a guide including at least a guide device, Characterized in that the guide device comprises an assembly side guide part and each assembly side guide part is arranged in a guide part carrier of the corresponding assembly, wherein the guide part carrier is attached separately to the corresponding assembly in each case Extrusion machines can be minimized.

Also, the effect of the moment and force generated by the extrusion on other parts of the extrusion machine is likewise an extrusion machine for pressurizing the billet through the die, including a billet container and an extrusion ram displaceable relative to the billet container and die, At least one assembly of the extrusion machine to which the rod is subjected during the extrusion due to the force and moment generated by the extrusion is motor-driven through the powered drive device, the powered drive device engages the assembly-side drive position, Wherein the drive position is arranged in the drive position carrier of the corresponding assembly in each case, the drive position carrier being separately attached to the corresponding assembly.

The extrusion machine can be a direct and indirect extrusion machine, because in this type of press, correspondingly large pressing forces act on certain assemblies of the direct or indirect extrusion machine. Even in the case of hydraulic presses, there are assemblies which can be subjected to a correspondingly large pressing force so that the solution described herein can be used. It is likewise contemplated that the solutions described herein may be used advantageously in piercing presses or other presses as well.

Optionally, a plurality of guide devices or powered drive devices may also be arranged on either side of the respective loaded assemblies, and thus each of the assembly side guide parts It is obvious that a plurality of guide devices or a powered drive device may be provided, each of which includes a drive-side drive position or another drive-side drive position.

As already mentioned above, a container holder holding the billet container or a crossbeam holding the extrusion ram can be used here as a loaded assembly. On the other hand, it is clear that a billet container or other extrusion ram can directly constitute the loaded assembly. Other assemblies which are subjected to a load during extrusion, which is sometimes induced by forces or moments generated by extrusion, and which are displaceably guided along a guide or motor-driven by a drive device which is otherwise powered, It is clear that a guide component carrier or a drive position carrier can be included as a loaded assembly. Possible examples here are in particular die or other corresponding dyrams or corresponding support beams or carriers. It is contemplated that the valve, seal, or line that is likewise subjected to the rod during the extrusion, which is likewise influenced by the material to be extruded and consequently also by the force and moment generated by the extrusion, can be conceived.

As already mentioned above, sliding blocks, sliding shoes or sliding rails, as well as any type of roller bearings are also possible, possibly as assembly-side guide parts. Therefore, at this time, the complementary frame side guide part may be a guide rail or the like, and in this case also, it may be reversed between the assembly side guide part and the frame side guide part. In this context, the guide parts are thus defined as such assemblies of guides or guide devices which are displaceably in direct contact with each other and which receive the guiding force.

This also applies to the assembly side drive position or else to the frame side drive position which represent both assemblies to the drive, are movable relative to each other and transmit forces, and the assembly side drive position is, for example, a rack gear or a piston, Moved and moved with the loaded assembly, and the frame-side drive position can be held fixedly on the corresponding frame and configured, for example, as a rack gear or a cylinder. It is also clear here that an exchange can be made between the assembly side drive position and the frame side drive position so that, for example, a rack gear or a cylinder can be provided on the assembly side and a corresponding drive pinion or piston can be provided on the frame side .

The assembly-side guide part and the frame-side guide part form a guide device together here. The assembly-side drive position and the frame-side drive position thus interact in the harnessed drive, and the harnessed drive further comprises a motor also driven electrically, pneumatically or hydraulic, in particular hydrostatic or hydrodynamic.

The assembly side guide parts are arranged here in the drive part carrier, the assembly side drive positions are respectively arranged in the drive position carrier, and the guide part carrier or the drive position carrier are separately attached to the respective assemblies, Thereby minimizing the influence of the moment or force generated by the extrusion on the part.

For example, an attached plate, bolt, profile carrier, and similar structure with other characteristics may be used as the guide component carrier or the drive position carrier. Thus, in particular, a drive bracket or guide bracket can be used if the corresponding rod is separately attached to the applied assembly.

Attachment of the guide component carrier and the drive position carrier allows a predetermined clearance to a fixed assembly such as a frame, thereby enabling the most accurate guide or the most precise drive. Attachment means that a corresponding amount of clearance is maintained, but nonetheless, the operative coupling between the guide component carrier and the driven position carrier and the corresponding load-applied assembly can be configured so that a sufficiently precise operating engagement is maintained in each guide direction or in each drive direction .

The attachment is preferably effected by a positive fit between the guide part carrier acting in the direction required for the guide and the corresponding rod-mounted assembly, or by a drive position carrier And a shape-fitting engagement between the corresponding load-applied assemblies.

Corresponding shape mating engagement can be provided, for example, by suitable abutments on the loaded assembly and guide component carrier or drive position carrier.

On the other hand, the attachment can be realized by a combination of rigidity that is greater than mounting or loose fit engagement, if sufficient clearance is allowed to allow corresponding load removal.

Attachment preferably includes a plurality of joining or shape fittings that ensure proper clearance and thus act from a plurality of sides thereby ensuring that the proper coupling or sufficient clearance in each case satisfies the requirement .

In this regard, the term "attachment" of the guide component carrier and the driven component carrier here means that the necessary guides or actuations, respectively, for the corresponding loaded assemblies are provided by the guide component carrier and the drive position carrier, ≪ / RTI > respectively, on the corresponding loaded assemblies.

If desired, the guide component carrier and the drive position carrier may be integrally configured or provided by the same assembly. In this respect, a drive bracket, which also has a corresponding load attached to the assembled body separately and which also holds at least one guide part in the assembly part, also acts as a guide part carrier and also as a drive position carrier. With this type of integral construction, a very compact structure is achieved and at the lowest cost it is achieved to very effectively minimize the effects of the extrusion-induced moments and forces on other parts of the extrusion machine.

It is contemplated that the loaded assembly may be guided using only a single guide device corresponding to that guide, but this requires that a single guide device exert all the moments and forces necessary for the guide alone, Can lead to long lever travels, which in turn means that a substantial load can be applied to the guide device. Thus, it may be advantageous for the guides to include at least two guide devices spaced apart from one another, e.g. placed on the opposite side on a loaded assembly, and in principle to generate the same guide path. This means that any moment or corresponding force does not increase too rapidly and a more reliable and uniform guide can be ensured. Thus, it is advantageous if each guide device comprises an assembly-side guide component, and the assembly-side guide component is respectively disposed on a guide component carrier on a corresponding assembly that is separately attached to the corresponding assembly at that portion.

It is clear that, in accordance with a specific implementation, a plurality of assembly-side guide parts can also be provided on the guide part carrier, in order to construct a corresponding guide device so that the guide is made as effective as possible.

In particular, three, four or more guide devices may also be respectively attached to the corresponding assemblies to ensure a sufficiently good guide, and the guide devices are preferably arranged symmetrically with respect to one another, for example rotationally symmetrical or mirror symmetrical. The symmetry corresponding to the direction of the average movement of the material to be extruded through the extrusion machine, relative to the extrusion axis is particularly favorable.

It is clear that, according to specific requirements, a plurality of harnessed drive devices, each spaced apart from one another on the loaded assembly, can also be provided, and also the above-mentioned symmetry can be considered. However, in accordance with specific requirements, there is no need for as many powered drives as there are guide devices to ensure the corresponding operational safety. In other cases, however, a plurality of small driving devices can be provided completely selectively, in particular, for example, in the case of a large press, in principle, when more driving force is required, and a large driving device can be omitted.

In the presence of a plurality of motorized drives, each powered drive is associated with an assembly-side drive position, and the assembly-side drive position is associated with a corresponding load on the corresponding load- It is also correspondingly advantageous to position each on a drive position carrier on the assembly.

At least one of the guide component carrier and / or drive position carrier or guide component carriers and / or at least one of the drive position carriers is advantageously attached to each assembly via at least one damping element. In this case, the damping element may damp any impact or jolts which may be generated by the extrusion machine in the direction of the guide or in the direction of the powered drive, thereby minimizing the effect thereof.

Whether a spiral spring or a leaf spring, a spring, plate spring or similar resilient assembly can possibly be used as a damping element, and friction for converting mechanical energy generated by impact or impact into heat energy Elements may also be provided if necessary. A hydraulic damping element which can have an energy-removing effect through the flow at the transition between the loaded assembly and the drive position carrier or the guide part carrier can advantageously be used in this case. Likewise, elastic elements have proven to be very advantageous as damping elements, because they may transmit forces and may also have an energy-removing effect.

The separate attachment of the guide component carrier or the drive position carrier is particularly facilitated when a driver acting in the direction of movement of the corresponding assembly is provided between the guide component carrier on one side and / or the corresponding assembly on the other side of the drive position carrier . Although any impact or impact acting in the effective direction of the driver is then transmitted, all other effective directions of impact or impact or other forces can not be transmitted through this type of driver or only very little can be delivered .

In particular, the corresponding driver may include an assembly-side abutment or other assembly-side stop and guide-component carrier side or drive-position carrier-side stop that may act in a carrying along manner.

The driver preferably interacts with the damping element, so that a particularly effective decoupling can be ensured. For this purpose, the driver and the damping element can be connected in series, for example, the damping element for this purpose can, for example, comprise a corresponding stop or corresponding junction. In an alternative embodiment, the damping element and the driver may be connected in parallel.

In order to minimize the effect of the extrusion-induced moment and force on other parts of the extrusion machine, an extrusion machine for pressing the billet through the die, comprising a billet container and an extrusion ram displaceable relative to the billet container and die , Wherein at least one assembly of the extrusion machine is motor-driven via a powered drive device, the powered drive device includes a motor-powered drive pinion and a rack gear, wherein the rack gear and the drive pinion engage with each other And the drive pinion is adjustably mounted on the drive position carrier with respect to the rack gear via an eccentric mechanism. The eccentric mechanism allows the drive pinion to be adjusted very precisely with respect to the rack gear irrespective of any clearance, so that there is no clearance to allow any type of impact or impact. In particular, backlashes can be optimally adjusted with respect to each other.

As a corresponding assembly, in particular the assemblies to which the loads have already been applied, as already mentioned above, can be motor driven in a corresponding manner, and the impact at the transition between the loaded assembly and the drive position carrier, Can be intercepted by separately attaching to the loaded assembly and the transition between the drive pinion and the rack gear does not counteract this separate attachment with an excessively large clearance.

Thus, it is advantageous that the eccentricity of the eccentric mechanism comprises a planar component which intersects the rack gear, and in this way the drive pinion can move to or away from the rack gear.

The drive position carrier preferably carries a motor, preferably an electric motor, of the drive train. It is clear that a motor comprising a hydrodynamic or otherwise hydrostatic motor, preferably a rotor, can also be used as the motor. Likewise, a linear motor may be used if advantageous.

However, the motor including the rotor is particularly advantageous in that it interacts with the drive pinion, whereby a very simple structural implementation can be achieved.

A safety clutch can be provided which acts as an overload release mechanism between the power-driven drive device and the drive position, e.g. between the drive pinion. In this way, the harnessed drive can be relieved of any impact or impact or other forces caused by extrusion. This type of safety clutch is preferably constructed, for example, of a friction clutch. However, it may also include a bursting disc or a bursting rod or the like as needed. In particular, friction clutches or torsional vibration dampers can advantageously be used as safety clutches, since the corresponding decoupling can be ensured in a non-destructive manner in this way.

The safety clutch can be provided between the gearbox provided between the drive position and the drive position, in particular, and the drive device energized, so that excessive force is not transmitted from the drive device into the gearbox, It relieves the load on the box and protects it from this point.

It is clear that the features of the solution described above or in the claims can also be combined as needed so as to derive advantages in a corresponding cumulative manner.

Other advantages, objects, and features of the present invention are described with reference to the following description of an exemplary embodiment, particularly shown in the accompanying drawings.

Fig. 2 is a detailed perspective view of a guide or a powered drive device of the extrusion machine according to Fig. 1; Fig.
3 is a schematic view of a transition between a loaded assembly of a device according to FIG. 2 and a guide part carrier or other drive point carrier.
4 is a schematic view from below the drive position;

The extrusion machining apparatus 10 shown in the drawing includes a frame 28 which in its part has a cylinder beam 64 and an opposing beam 66 and a tie rod 68 ). Each of the tie rods 68 includes a tension member or a pressure member, the tension member or the pressure member not being given a reference numeral because it is appropriately known from the prior art, and the tie rod may possibly be integrally formed.

The main cylinder 60 is arranged on the cylinder beam 64 in a known manner in the case of the extrusion processing machine 10 and the extrusion ram 16 is moved to the die 12 along the press axis 54 through the main cylinder And the die is fixed to the opposing beam 66 at that portion so as to exert a pressing force.

Further, the extrusion processing machine 10 includes a billet container 14 for housing a billet to be extruded during extrusion, so that the material can only come out through the die 12.

For extrusion, the extrusion ram 16 is of a relatively long construction, which can enter the billet container during extrusion and press the billet through the billet container 14 to the die 12.

Thus, the extrusion machine 10 operates as a direct extrusion machine, and in the case of a direct extrusion machine as an alternative embodiment, the extrusion ram 16 is of a correspondingly short construction and the die 12 is arranged on the dummy ram. In the case of more complex die presses, such as, for example, continuous extrusion machines, the different embodiment extruded rams and dies include ram shapes and provide substantially more complex transfer cycles.

For loading and the like, the billet container 14 may be axially displaced from the guide 20 to the press axis 54. To this end, the billet container 14 is attached to a container holder 72, which in turn comprises a corresponding guide device 22, which is described in detail below.

Likewise, the extrusion ram 16 is fixed to the crossbeam 70 to which the guide device 22 is attached at that part, which in turn likewise permits the guide along the guide 20. It is clear that in other embodiments, other assemblies that are loaded by the pushing force and moment may also be displaceably provided along the guide 20 and other guides.

In this exemplary embodiment, four guide devices 22 are provided on the crossbeam 70 and container holder 72, respectively, so that the tilting, etc., can be minimized and the structural conditions May be used for guiding through tie rod 68.

In this exemplary embodiment, the crossbeam 70 is also connected to a side cylinder 62, which is likewise supported on the cylinder beam 54 and operable against the extrusion direction and against the extrusion direction. In this way, axial movement of the cross beam 70 along the guide 20 is ensured.

As can be seen, the die 12, the billet container 14 and the associated container holder 72 and also the extrusion ram 16 and the crossbeam 70 are extruded by extrusion-induced forces and moments Lt; RTI ID = 0.0 > 18 < / RTI > The latter is proved to be relatively non-critical because it remains stationary relative to the frame in the case of die 12 and the billet container 14 is shown with the container holder 72 and the extrusion ram 16 is shown as a cross beam Along with guide 70, so that the corresponding rod also reaches guide 20 and the associated drive.

In this exemplary embodiment, the billet container 14 or the powered drive device 32 of the container holder 72 is connected to an electric motor (not shown) that drives the drive pinion 46 via the gearbox 56 and the safety clutch 58 And this drive pinion acts as the assembly-side drive position 34. The drive-

The drive pinion 46 is engaged with a rack gear 48 that acts as a frame side drive position 36 and is fixed in a fixed manner to the tie rod 68 at that portion.

The electric motor 52, the gear box 56 and the drive pinion 46 are fixed via the eccentric mechanism 50 to the drive position carrier 38 acting as a drive bracket.

The drive bracket or drive position carrier 38 also acts as a guide part carrier 30 and has a sliding block for this purpose which is arranged as a guide part 24 on the assembly side, And each guide device also includes a guide rail as the frame side guide part 26, and the guide rail and the sliding block interact with each other.

In this exemplary embodiment, each guide device 22 includes two frame-side guide pieces 26 arranged at right angles to each other and operable along the guide 20 and two guide pieces 24 on the assembly side, Side guide pieces 26 are disposed as two sliding rails on the tie rods 68, respectively.

The guide component carrier 30 and the drive position carrier 38 are also attached separately to the container holder 72 and thus to the billet container 14 which in this exemplary embodiment comprises a damping element 40 by means of a driver 44 which can interact with the damping element 40 and also by placing the loaded assembly 18 on the guide part carrier 30 or on the drive position carrier 38.

In this exemplary embodiment, the driver 44 includes two assembly-side joints 74, each of which is provided by the damping element 40, and also on the guide component carrier 30 or drive position carrier 38 And two guide parts or drive position carrier side joints 76 that are supplied by a driver attachment 78 disposed in the drive position carrier side joint 76. If a corresponding abutment 76 is provided on the guide component side or on the drive position carrier side, in other embodiments the driver attachment 38 may be integrally configured on the guide component carrier 30 or the drive position carrier 38 It is clear that. It is likewise contemplated that in other embodiments a corresponding damping element 40 may be provided that creates a guide component side or drive position carrier side junction 76. Similarly, the assembly side abutment 74 may be provided by the container holder 72 or the billet container 14 or the loaded assembly 18 as well.

In some cases, it is clear that the driver 44 can also be operated only on one side if it is intended to drive or guide forces in only one direction.

As can be seen, the force acting on the driver attachment 78, that is, the force that runs through the damping element 40 in parallel with the press axis 54, is effectively absorbed. The force generated at right angles to the other loose joint is not transmitted by the joint in any case, since in this case only frictional engagement is present. It is also clear that, in some cases, the damping element 40 and the corresponding resilient element 42 may also house a driver attachment to facilitate a more intensive guide.

The bearing means of the loaded assembly 18 on the guide component carrier 30 or the drive position carrier 38 may possibly be provided by a damping element such as a rubber mat or spring.

In this case, the guide device 22, including its guide part carrier 30, and also the drive position carrier 38 or other powered drive device 32 is described with respect to only one guide position or drive position .

As described above, this exemplary embodiment includes at least four guide devices 22 of this type that are separately attached to the container holder 72 symmetrically about the extrusion direction. It is clear that in other embodiments, more or fewer guide devices 22 may be provided, as the case may be.

Further, in the present exemplary embodiment, only the guide element carrier 30 disposed below the main extrusion direction through the press axis 54, i.e., the extrusion machine 10, is also configured as the drive position carrier 38, Since it is ultimately sufficient for proper operation of the billet container 14 in the preferred embodiment. It is clear that in other exemplary embodiments all of the guide component carriers 30 may be configured as the drive position carrier 38 and thus provide a powered drive device 32. [ Accordingly, it is also conceivable that only one of the guide component carriers 30 is configured in another embodiment.

It is also clear that in other embodiments it is not possible to retain the guide part 24 on the assembly side and thus the drive position carrier 38 rather than the guide part carrier 30. [ Which then acts only as a powered drive 32.

In the present exemplary embodiment, the crossbeam 70 is driven by the main cylinder 60 and the side cylinder 62, while in another embodiment the crossbeam 70 is simultaneously driven by a drive position carrier 38 along the guides 20 by means of the power-driven drive device 32. [0035] In this exemplary embodiment, four guides (not shown) that do not act as the drive position carrier 38 and interact with the frame side guide component 26 of the guide device 22 of the container holder 72 or billet container 14, A device 22 is provided on the crossbeam 70.

It is also clear that, for other guided assemblies, likewise, where any extrusion-induced forces and moments are exerted, corresponding guiding devices and powered drives can be provided.

It is also clear that the damping element 40 may be provided instead of the elastic element 42 and the damping element comprises a spring, for example a spiral spring or a leaf spring. Plate springs can also be considered. If necessary, an additional friction device may be provided here to improve the damping effect.

In this exemplary embodiment, the eccentricity of the eccentric mechanism 50 includes a planar component that intersects the rack gear 48 as seen in FIG. 4, and the projection plane constitutes a corresponding plane. In this way, the drive pinion 46 can be optimally adjusted with respect to the side surface of the rack gear 48, which is preferably done only during maintenance operations, and as a result, may offset wear if desired. To effect corresponding adjustment, the eccentric mechanism is preferably jammed or jammed, which is in principle known from the corresponding eccentric mechanism in principle.

A safety clutch 58 is provided as a friction clutch between the gear box 56 and the electric motor 52 in this exemplary embodiment. This type of friction clutch, in principle, has the advantage that it is operated without maintenance and its operation reliability is not lost when slippage occurs. Whereby the gearbox 56 can also be relieved of the excessive force that can be applied by the electric motor 52. [

Alternatively, if the gearbox 56 is to be protected from impact and the excessive force of the electric motor 52 is negligible with respect to the gearbox 56, then the safety clutch may possibly be engaged with the gearbox 56 and the drive pinion 46, or other assembly-side drive position 34. The drive-

If necessary, the sensor can optimize the associated process by sending a corresponding slip-Fi signal. It is clear that, instead of this type of friction clutch, advantageously a busting rod or busting disc or other torsional vibration damper may be used. If necessary, the latter can also be supplemented.
