It is proposed that the coil carriers can be brought into a coil winding position with respect to one another, in which the coil carriers are oriented with the associated coil axes coaxially to a geometrical winding axis, wherein the coil carriers can be brought with respect to one another into a mounting position in which the coil carriers are offset with the associated coil axes in parallel and/or at an angle with respect to one another, and wherein the coil carriers are coupled mechanically to one another in the coil winding position and/or in the mounting position.

Description

Coil support arrangement

The invention relates to a coil carrier arrangement for a coil arrangement of an electrical rotary drive of a motor vehicle lock according to claim 1, a coil arrangement having at least one coil carrier arrangement according to claim 6, a drive of a motor vehicle lock according to claim 11, a motor vehicle lock according to claim 14 and a method for producing a coil arrangement according to claim 18th

The coil carrier arrangement in question is assigned to a drive of a motor vehicle lock. Such a motor vehicle lock is used in all types of closure elements of a motor vehicle. These include in particular side doors, rear doors, tailgates, trunk lids or hoods. In principle, these closure elements can also be designed in the manner of sliding doors.

The known coil carrier arrangement (DE 10 2012 003 698 A1), from which the invention proceeds, is associated with a coil arrangement of an electric rotary drive of a motor vehicle which is designed in the manner of a stepping motor. The drive here serves to set different closing states of the lock mechanism of the motor vehicle lock. This coil arrangement is equipped with a plurality of linear coil windings, which are received by the coil carrier assembly. The coil carrier assembly provides a magnetic inference at the same time in this case.

A challenge in the known coil support arrangement is the winding of the coil support assembly for generating the coil windings. Here, usually the known needle winding technique is used, in which a wire guide, which is arranged on a needle carrier, in addition to a rotary winding movement performs an alternating movement along the respective coil axis. Since this is done with fully assembled coil carrier assembly, the available space for the winding is extremely limited. This in turn means that preferred types of winding, such as an orthocyclic winding, are hardly feasible. Incidentally, the processing times for winding the coil carrier assembly are relative high. Finally, a Nadelwickelanlage is mechanically complex, which leads to correspondingly high costs.

The invention is based on the problem of designing and further developing the known coil carrier arrangement in such a way that the winding process is optimized, in particular with regard to process time and process flexibility, with little constructive effort.

The above problem is solved by a coil carrier assembly according to claim 1.

The basic idea is to equip the coil carrier assembly with at least two coil carriers, which can be brought to each other in different positions. This makes it possible, in particular, to bring the coil carriers to one another in a position which enables a simple winding of the coil carriers.

In detail, it is initially proposed that the coil carriers can be brought into mutual arrangement with one another in a coil winding pitch, in which the coil carriers with the associated coil axes are aligned coaxially on a geometrical winding axis. It is further proposed that the coil carriers can be brought to one another in a mounting position in which the coil carrier with the associated coil axes are offset parallel to each other and / or angularly offset. From the assembly position, all further assembly steps for completing the drive can be made.

The bobbins are according to the proposal mechanically coupled together in the coil winding pitch and / or in the mounting position, so that a simple and in particular automated handling of the coil carrier arrangement is possible borrowed.

With the proposed coil carrier arrangement, the coil carriers located in the coil winding division can be wound simply by causing the coil carrier arrangement to rotate as a whole, while a wire guide nozzle merely has to perform a linear movement along the coil axis. Since the coil carriers of the coil carrier arrangement are coaxial long of the geometric winding axis, the bobbin can be sequentially or simultaneously wrap without a complicated positioning of the wire guide nozzle is required. This initially leads to low process times. In addition, results from the flexible motion control of the wire guide nozzle a higher flexibility in the selection of the respective type of winding. In particular, an orthocyclic winding, which allows a large filling factor of the winding can be implemented easily.

A mechanically robust and easy-to-handle arrangement is the subject matter of claim 3, in which a hinge arrangement is provided between two carrier sections of the coil carrier arrangement. In the further preferred embodiment according to claim 4, a latching fixation of the two carrier sections is provided to each other in the coil winding position and / or in the mounting position. This further improves the particularly automated handling of the coil carrier arrangement.

According to a further teaching according to claim 6, which has independent significance, a coil arrangement with at least one proposed coil carrier arrangement is claimed as such. Reference may be made to all versions of the proposed coil carrier arrangement.

In the particularly preferred embodiment according to claim 7, the coil assembly is equipped with at least two coil support assemblies which are mechanically connected to each other by means of a coupling arrangement. A manufacturing technology particularly advantageous variant provides that the coil carrier assemblies of the coil assembly are configured identical to each other.

According to another teaching according to claim 11, which also has independent significance, the drive of a motor vehicle lock is claimed with a proposed coil assembly. Reference may be made to all versions of the proposed coil arrangement and to the proposed coil support arrangement.

In a particularly preferred embodiment according to claim 12, the drive is configured as Axialflussmotor having a coil arrangement with at least two parallel to a drive axis aligned coils. Here are the Coil carrier assemblies, based on a rotor plane of the drive, arranged on opposite sides (claim 13). The adjustment of the bobbin between the bobbin winding position and the mounting position is then preferably possible with a within the scope of an automated production easy to be realized pivoting movement by 180 °.

According to another teaching according to claim 14, which also has independent significance, a motor vehicle lock is claimed with a proposed drive as such. All versions of the proposed drive may be referred to.

According to another teaching according to claim 18, which in turn has independent significance, a method for producing a coil arrangement of an electric rotary drive of a motor vehicle lock is claimed. Again, there is a coil carrier assembly with at least two coil carriers application, each with a coil winding, in particular a linear coil winding can be wound. Although it is preferred that the coil carriers in the coil winding position and / or in the assembly position are mechanically coupled to one another as mentioned above, this is not absolutely necessary for the proposed method.

According to the proposal, it is so that in a first alignment step, the coil carriers are brought to each other in a coil winding position mentioned above, in which the coil carrier are aligned with the associated coil axes coaxially on a geometrical winding axis. In a subsequent coil winding step, the coil carriers are each wound around the winding axis by a rotation of the coil carrier arrangement with a coil winding. In a subsequent, second alignment step, the coil carriers are brought to each other in an assembly position in which the coil carrier offset with the associated coil axes parallel to each other and / or angularly offset. From the assembly position can then follow further assembly steps to complete the drive.

With the proposed method, the mechanical adjustability of the coil support assembly for an optimal winding process can be fully utilized. In particular, the proposed method comprises exclusively a multiple movements that can be performed automatically without further ado. This includes, for example, that, in particular for the production of an axial flow motor, a pivoting of the coil carriers relative to each other by about 180 ° is sufficient to achieve the assembly position.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. In the drawing shows

1 shows a proposed drive a proposed motor vehicle lock in a very schematic representation, which is equipped with a proposed coil assembly and a proposed coil support assembly,

2 shows the drive according to FIG. 1 without housing, FIG.

3 shows the drive according to FIG. 1 without housing in a partially exploded view, FIG.

Fig. 4 is a coil carrier assembly of the drive according to FIG. 1 in located in the coil winding division coil carriers and

Fig. 5, the bobbin assembly of FIG. 4 in located in the assembled position bobbins.

The proposed coil support assembly 1, 2 is part of a coil assembly 3, which in turn is part of an electric rotary drive 4 of a motor vehicle lock 5. The drive 4 is used for the motorized adjustment of the functional state of a lock mechanism 6 of the motor vehicle lock. For this purpose, the drive 4 operates in the manner of a stepping motor on an actuating element 7, which is preferably designed as a control shaft. The basic operation of the motor vehicle lock 5 will be explained below. For the rest, in particular with regard to the interaction of the drive 4 with the motor vehicle lock 5 via the control shaft 7, reference may be made to the German patent application DE 10 2012 003 698 AI, which is based on the applicant and whose contents are hereby made the subject of the present application. ¹ As mentioned above, the coil arrangement 3 has two coil carrier arrangements 1, 2. Insofar as only a single coil carrier arrangement, in particular the coil carrier arrangement 1 shown in FIGS. 4, 5, is explained below, these explanations apply correspondingly to the respective other, identical coil carrier arrangement 2 here.

Fig. 5 shows in detail that the coil support assembly 1 with two coil carriers 8, 9 (coil support 8a, 9a for the coil support assembly 2) is equipped, each with a linear coil winding 10, 11 (linear coil winding 10a, I Ia for the Spulenträgeranordnung 2) are wound. The coil carriers 8, 9 are mutually engageable in a coil winding pitch, in which the coil carrier 8, 9 with the associated coil axes 12, 13 (coil axes 12a, 13a for the coil support assembly 2) are coaxially aligned with a geometric winding axis 14. This is shown in Fig. 4.

According to the proposal, the coil carriers 8, 9 are adjustable relative to one another such that the coil carriers 8, 9 of the coil carrier arrangement 1, 2 can be brought to one another in an assembly position, which is shown in FIG. 5. In the assembly position, the coil carriers 8, 9, with the associated coil axes 12, 13 offset from each other in parallel. Alternatively or additionally, the coil carrier 8, 9 with the associated coil axes 12, 13 also be angularly offset. The respective offset depends essentially on the design of the drive 4, as will be explained.

4 and 5, it can be seen that the coil carriers 8, 9 are mechanically coupled to one another in the coil winding position (FIG. 4) and in the assembly position (FIG. 5). It can be seen from these illustrations that good handleability of the coil carrier arrangement 1 is ensured by this coupling in both positions. In principle, it can also be provided here that the mechanical coupling is provided only in the coil winding position or only in the assembly position.

A combination of FIGS. 4 and 5 further shows that the coil carrier arrangement 1 has at least two carrier sections 15, 16, here and preferably exactly two carrier sections 15, 16 (carrier sections 15a, 16a for the coil carrier). Arrangement 2), each having at least one of the coil carrier 8, 9. The carrier sections 15, 16 are mutually adjustable for the transition from the coil winding position (FIG. 4) to the assembly position (FIG. 5). In a particularly preferred embodiment shown here, it is such that the carrier sections 15, 16 are pivotable relative to one another about a pivot axis 17 (pivot axis 17a for the coil carrier arrangement 2). Specifically, a mechanical coupling between the support sections 15, 16 is provided here, which provides a pivot bearing about the pivot axis 17. The pivot axis 17 is here and preferably aligned substantially perpendicular to a geometrical drive shaft axis 18. In the drive shaft axis 18 is the geometric axis to which the drive shaft 19 of the drive 4 is aligned. With such a pivotable coupling of the two support portions 15, 16, the two above positions of the bobbin 8, 9 can be adjusted by appropriate folding movements.

The carrier sections 15, 16 are at least partially made of a plastic material in the sense of cost-effective production. They are so easy to produce by plastic injection molding.

In the illustrated preferred embodiment, the coupling between the support portions 15, 16 for the realization of the pivot axis 17 (pivot axis 17a for the coil support assembly 2) on a hinge assembly 20 (hinge assembly 20a for the coil support assembly 2), the two form and / or having non-positively engaged hinge parts 21, 22. Alternatively, the hinge assembly 20 may also be designed in the manner of a film hinge, which is cost-technically advantageous.

In terms of good automation, it is further preferably provided that a fixing arrangement for the support sections 15, 16 is provided, with the at least two support sections 15, 16, here the two support sections 15, 16, in the coil winding position and / or in the mounting position mechanically , in particular latching, are fixable to each other, so that an above pivoting of the support sections 15, 16 is locked against each other. This eliminates the need for separate fixing devices, which would be necessary in order to ensure automated handling. The illustrated fixing arrangement 40 serves to fix the carrier sections 15, 16 in the assembly position. It preferably has at least one latching element 41a, 41b, here and preferably two latching elements 41a, 41b, as well as at least one counter-latching element 42a, 42b, here and preferably two Gegenrastele- elements 42a, 42b, which in the coil winding position and / or in the mounting position engage with each other in a restraining manner. This is best understood from a synopsis of the illustrations according to FIGS. 4 and 5. Here, the latching elements 41a, 41b configured as convex protrusions, which interact with substantially concave counter-locking elements 42a, 42b to fix the support portions 15, 16 in the mounting position.

After winding of the coil carriers 8, 9, the coil carriers 8, 9 are each equipped with a coil winding 10, 11. A simple contacting of the coil windings 10, 11 is of particular importance for the economy of production. Here and preferably, the winding ends 23, 24 of the coil windings 10, 11 arranged adjacent to one another in FIG. 4 are simply ground through, so that in this respect a contacting problem does not arise at all. By this is meant that the winding end 23 of the coil winding 10 is at the same time the corresponding winding end 24 of the coil winding 11, as shown in Fig. 4. In this sense, the winding ends 23, 24 are not free, cut-off winding ends.

Here, and preferably, it is such that in the region of the hinge arrangement 20, a winding wire guide 25 is provided for the winding ends 23, 24 of two adjacent coil windings 10, 11 in the coil winding state. In a particularly preferred embodiment, the winding wire guide 25 may also have a length compensation arrangement for the winding ends 23, 24 with respect to an adjustment of the bobbin 8, 9 of the coil winding state in the assembled state.

An above coil arrangement 3 is also the subject of an independent teaching. It is essential that the coil assembly 3 at least two, here exactly two, coil support assemblies 1, 2, which are mechanically interconnected by means of a coupling assembly 26, here and preferably latching. The coupling arrangement 26 has here and preferably at least one Locking element, here and preferably two locking elements 27a, 27b, and at least one counter-locking element, here and preferably two counter-latching elements 28a, 28b, which are engageable with each other during assembly.

The fact that both coil carrier arrangements 1, 2 each have two latching elements 27a, 27b and two counter-latching elements 28a, 28b, each latching with the latching elements or counter-latching elements of the respective other coil carrier arrangement 1, 2, is interesting in the exemplary embodiment shown can be brought into engagement. In particular, for the latter embodiment, it is advantageous that the coil support assemblies 1, 2 are configured identical to each other. In general, this results in a particularly simple manufacturability.

As mentioned above, the two coil windings 10, 11 of a coil carrier arrangement 1, 2 are connected in series by looping through the respective coil ends. The respective outer winding ends of the coil windings 10, 11 in FIG. 4 are electrically coupled to corresponding contact arrangements 29, 30.

The contact arrangements 29, 30 are used for electrical contacting of the coil windings 10, 11 and are here and preferably equipped with corresponding insulation displacement terminals 31, 32. Alternatively, it may be provided that the contact arrangements 29, 30 each have a plug contact o. The like. Other ways of contacting are soldering, welding or bonding o. The like. Back.

It can be seen from the illustrations according to FIGS. 3 and 4 that the contact arrangements 29, 30 are at least partially part of the respective support section 15, 16. Here and preferably, it is such that at least one contact arrangement 29, 30 is designed in one piece with the respective support section 15, 16. This can be realized particularly advantageously if the respective support section 15, 16 is at least partially made of a plastic material.

2 shows a structurally advantageous construction of the coil arrangement 3 in that the coil carrier arrangements 1, 2, here and preferably taken together, provide a particular closed housing that receives the rotor 34 of the drive 4. This dual function of the coil assembly 3 results in a compact and inexpensive design.

According to another teaching, which also has independent significance, the illustrated drive 4 of the motor vehicle lock 5 is claimed as such. It is essential that the drive 4 is equipped with a proposed coil arrangement 3 explained above.

Here and preferably, the drive 4 is configured as an axial flux motor, which has a coil arrangement 3 with at least two coil windings 10, 11 aligned parallel to the drive shaft axis 18. Alternatively, the drive 4 may also be designed as a radial flux motor, the coil arrangement then having at least two coil windings oriented radially relative to the drive shaft axis 18.

In particular for the configuration of the drive 4 as an axial flux motor, it is preferably such that the coil arrangement 3 has two coil carrier arrangements 1, 2, which are arranged on opposite sides with respect to a rotor plane 33 of the drive 4. This is best seen in the illustration of FIG. 3. The rotor plane 33 is defined here in that the rotor 34 of the drive 4 is arranged in the rotor plane 33. The rotor plane 33 is aligned correspondingly perpendicular to the drive shaft axis 18.

The rotor 34 of the drive 4 is here and preferably equipped with a permanent magnet arrangement, which cooperates with the magnetic field generated by the coil assembly 3, resulting in corresponding drive torques. In principle, however, the rotor 34 may also be equipped with a coil arrangement.

It may also be advantageous for the coil arrangement 3 to have more than two coil carrier arrangements 1, 2. In a particularly preferred embodiment, and in particular for the configuration of the drive 4 as Axialflussmotor it is provided that the coil assembly 3 has four coil support assemblies, which are arranged in pairs on the rotor plane 33 of the drive 4 on opposite sides. Further, it is conceivable that the coil support assemblies 1, 2 are aligned with respect to the drive shaft axis 18, so that relative to the rotor plane 33 respectively opposite coil windings 10, 11 are each aligned coaxially to each other. Preferably, however, it is the case that the coil carrier arrangements 1, 2 arranged on opposite sides relative to the rotor plane 33 are arranged offset by 90 ° relative to the drive shaft axis 18.

It should also be noted that the drive 4 is preferably designed in the manner of a stepping motor. In principle, however, it may be advantageous that the drive 4 is designed as a continuously and in particular endlessly rotating motor.

According to another teaching, which also has independent significance, a motor vehicle lock 5 is claimed with a proposed drive 4 as such. As explained above, the motor vehicle lock 5 is associated with an actuating element 7 which is motor-adjustable by means of the drive 4.

As already indicated, the drive 4 serves to set various functional states of the motor vehicle lock 5. For this purpose, the motor vehicle lock 5 initially has a lock mechanism 6 which is locked in different functional states such as "locked", "unlocked", "anti-theft", "locked". In this connection, it should be pointed out that the lock mechanism 6 can be brought into any selection of the above functional states by means of the drive 4. In particular, it can be provided that the lock mechanism 6 by means of the drive It is also conceivable that, in addition to the two last-mentioned functional states, the functional state "anti-theft" can be set by means of the drive 4.

Here and preferably, the control element 7, in particular the control shaft, can be brought by means of the drive 4 in at least two control positions to functional states of the lock mechanism 6 as "locked", "unlocked", "theft-proof", "locked-child-proof" and "unlocked-child "to adjust. Preferably, it is such that each control position of the actuating element 2 corresponds to a functional state of the lock mechanism 6, so that for setting the respective functional state, the adjusting element 7 is to be brought into the corresponding control position.

To set the various functional states, the lock mechanism 6 is equipped with an adjustable functional element 6a, wherein the adjusting element 7 is directly or indirectly in driving engagement with the functional element 6a or can be brought. For the sake of clarification, it should be pointed out that the drive technology intervention can also be implemented via any desired number of gear elements. In principle, however, it can also be provided that the adjusting element 7 is part of the functional element 6a.

Preferably, it is such that the functional element 6a is supported on a control section of the actuating element 7. Depending on the position of the adjusting element 7, the functional element 6a is adjusted substantially perpendicular to the actuating element axis 7a, as shown in FIG. 1 by the movement arrow 6b and by the dashed representation of the functional element 6a. The control section is preferably equipped, as shown in FIG. 1, with a cam 6c on which the functional element 6a is supported accordingly. Depending on the position of the adjusting element 7, the support of the functional element 6a on the cam 6c leads to a resulting deflection of the functional element 6a in the direction of the movement arrow 6b.

The actuator 7 can be by means of the drive 4 in at least two control positions, here and preferably in a total of five control positions bring to the functional states of the motor vehicle lock 5, here the functional states "locked", "unlocked", "theft-proof", "locked-kindergesi - chert "and" unlocked-child-proofed "to be able to adjust.

The structure of the proposed motor vehicle lock 5 is particularly simple in that the functional element 6a is designed as a wire and can be deflected into different functional positions along the movement arrow 6b. In principle, it is also conceivable that the functional element 6a is designed as a strip. Here and preferably, it continues to be that Functional element 6a is designed as a resilient wire or strip, and so can be brought as a bending-Fünktionselement in the different functional positions.

The mode of operation of the motor vehicle lock 5 in the functional states "unlocked" and "unlocked-child-proof" is explained below. Incidentally, in order to explain the basic mode of operation of the motor vehicle lock 5 with resilient functional element 34, reference may be made to the German patent application already referred to above.

In the functional state "unlocked", the functional element 6a is in its lower position shown in solid line in Fig. 1. Thus, the functional element 6a is in the range of motion of an internal operating lever 6d, which is coupled in the mounted state with a door inner handle, and in the range of movement of an external operating lever An adjustment of the inner operating lever 6d or the outer operating lever 6e in the direction of the movement arrow 6f results in the functional element 6a, perpendicular to its extension, following the movement of the respective lever 6d, 6e on the in Fig. 1 only indicated pawl 6g hits and this in turn takes in the direction of the movement arrow 6f and lifts.

An adjustment of the adjusting element 7 in the direction of the movement arrow 6h by 90 ° from the position shown in Fig. 1 leads to the setting of the functional state "unlocked-child-proof." In this state, the functional element 6a is in the in Fig. 1 in dashed line An adjustment of the inner actuating lever 6d in the direction of the movement arrow 6f thus has no effect on the functional element 6a and the pawl 6g However, the functional element 6a is still in the range of movement of the external actuating lever 6e, so that a lifting of the pawl 6g and thus an opening the vehicle door via the external operating lever 6e and thus on the outside door handle is possible.

Analogous to the setting for the above-described functional states "unlocked" and "unlocked-child-proofed", all the other functional states mentioned above can be controlled solely by a corresponding adjustment of the functional state Implement actuating element 7. The drive 4 is designed to approach all functional states accordingly.

With regard to the adjustment of the adjusting element 7, the drive 4 preferably operates as a direct drive, as has been waived between the actuator 7 and the drive 4 to any gear components. Here and preferably, the drive 4 is mechanically not designed to be self-locking, which allows an unproblematic manual adjustment of functional states of the motor vehicle lock.

According to another teaching, which also has independent significance, a method for producing a coil arrangement 3 of an electrically rotary drive 4 of a motor vehicle lock 5, which is mentioned above, is finally claimed. The proposed method is based on at least one coil support arrangement 1, 2 with at least two coil carriers 8, 9, each with a coil winding, in particular with a linear coil winding 10, 11, are wound. Although a mechanical coupling of the coil carriers 8, 9, in particular via a hinge arrangement 20 mentioned above, is advantageous, it is not absolutely necessary for the further teaching. This has already been indicated above.

In a first alignment step, the bobbins 8, 9 are brought to each other in the above-mentioned coil winding position, which is shown in Fig. 4. The coil carrier 8, 9 with the associated coil axes 12, 13, coaxially aligned with a geometric winding axis 14. Further preferably, the coil carrier assembly 1, 2 is pushed onto a motor-driven winding shaft 35 of a coil winding machine, not shown in the rest, which is indicated in Fig. 4. The cylindrical hollow volume 36 of the coil carriers 8, 9, which are aligned with the respective coil axes 12, 13, serve as a receptacle for the winding shaft 35. In the assembled state, iron cores (not shown) are used for the magnetic reflux in this hollow volume.

In a subsequent coil winding step, the coil carriers 8, 9 are each wound around the geometric winding axis 14 by a rotation of the coil carrier arrangement 1, 2 with a linear coil winding 10, 11. The rotation The coil carrier assembly 1, 2 results from the motor drive of the winding shaft 35. Accordingly, it is here and preferably provided that the coil carrier assembly 1, 2 rotatably mounted on the winding shaft 35 is arranged. The winding process is merely indicated in FIG. 4 by means of a wire guide nozzle 37 which can only be moved in two linear axes. The course of the tool reference point 38 of the wire guide nozzle 37 still present in FIG. 4, at which the winding wire W emerges from the wire guide nozzle 37, is shown in FIG. 4 indicated by the reference numeral 39.

As mentioned above, the coil winding step begins with the electrical coupling of the winding wire W to the contact arrangement 29, here via the insulation displacement terminal 31, by a corresponding advance of the wire guide nozzle 37 along the contact arrangement 29. Thereafter, the Wik- no coil winding 10 and then the winding of the coil winding 11 by corresponding feeds of Drahtfuhrungsdüse 37 to the bobbins 8, 9 along. Finally, the electrical coupling of the winding wire W takes place with the contact arrangement 30, in this case via the insulation displacement terminal 32. This is again effected by a corresponding advance of the wire guidance nozzle 37 along the contact arrangement 30.

The coil winding step is followed by a second alignment step, in which the coil carriers 8, 9 are brought to one another in the assembly position shown in Fig. 5. In the assembly position, the coil carrier 8, 9 with the associated coil axes 12, 13, as explained above, offset from each other in parallel. Alternatively or additionally, a corresponding angular offset can be provided. From this mounting position can be made further downstream mounting steps. These include, for example, the particular latching mounting of the two coil carrier arrangements 1, 2 shown in FIG. 3 with the inclusion of the rotor 34, in particular by means of a coupling arrangement 26 mentioned above.

It can be seen from a combination of FIGS. 4 and 5 that the transfer of the coil carriers 8, 9 from the coil winding state into the assembled state in each case results in a pivoting of the coil carriers 8, 9 relative to one another by approximately 180 °. back goes. Such a folding movement can be easily implemented automatically, as already mentioned above.

Preferably, in the coil winding position along the winding axis 14 successively arranged coil carrier 8, 9 are wound in this order. Alternatively, however, it can also be provided that at least two coil carriers 8, 9 are wound simultaneously in order to save process time.

As has also already been mentioned above, the winding ends 23, 24 of the coil windings 10, 11 arranged adjacent to the winding axis 14 in the coil winding position are ground through here and preferably in the coil winding step. This means that after completion of the winding of the coil winding 10, the winding of the coil winding 11 follows, without the winding wire W is separated. Preferably, it is such that between the winding of the coil windings 10, 11 of the winding wire W via the above-mentioned winding wire guide 25 is guided. For a defined course of the winding wire W is guaranteed.

Interesting in the exemplary embodiment shown in FIG. 4 and so far preferred is the fact that towards the end of Bewickelins the bobbin 8 located at the respective winding point winding end of the resulting coil winding 10 on the side of the bobbin 8 manages the subsequent to be wound bobbin. 9 is facing. This can be realized most simply by the fact that the number of wire layers at least of the coil winding 10 is odd.

Due to the simple structure shown in FIG. 4, the coil windings 10, 11 can be wound in linear winding technology. The wire guide nozzle 37 is advantageously, as mentioned above, to be adjusted in only two linear axes. In a particularly preferred embodiment, the coil windings 10, 11 are wound in orthocyclic linear winding technique, whereby a particularly high filling density of the respective coil windings 10, 11 can be achieved.

In an overall view of the figures, a very special advantage of the proposed solution, the above-mentioned, manufacturing technology Benefits goes beyond. Depending on the drive direction of the winding shaft 35, different winding directions can be realized in the coil windings 10, 11 of a coil carrier arrangement 1, 2. In that regard, the flexibility in terms of the resulting winding directions is high. In the case of the above-mentioned looping through complicated winding combinations can be realized without this leading to a manufacturing overhead.
