Description

Driving unit

Technical Field

The invention relates to a drive unit of a drive device for adjusting an adjusting element of a motor vehicle according to the preamble of claim 1, a drive unit of a drive device for adjusting an adjusting element of a motor vehicle according to the preamble of claim 19, a drive unit of a drive device for adjusting an adjusting element of a motor vehicle according to the preamble of claim 20, and a drive device for adjusting an adjusting element of a motor vehicle according to claim 21.

Background

The concept "adjusting element" should be understood here in a broad sense. It comprises, for example, a cover plate (klapp en), for example a tailgate, a motor cover, a side door, a cargo compartment flap, etc. of a motor vehicle or a sliding door.

The known drive device (DE 102008062400 A1) on which the invention is based has a drive device for adjusting a tailgate of a motor vehicle, which drive device is designed as a screw drive. The drive device has a drive unit with an electric drive motor and a feed transmission in the form of a screw-screw nut transmission, which is coupled to the drive unit in terms of drive technology, for producing a drive movement along a geometric drive axis between a first and a second drive connection of the drive device. The screw-screw nut transmission has, in a manner customary per se, a screw driven by a drive unit and a screw nut which engages with the screw and which, as a result of its being torsionally locked, converts the rotational movement of the screw into a linear movement of the two drive connections relative to one another. In this way, the tailgate can be electrically adjusted between an open position and a closed position.

The drive unit further has a cable module with a motor circuit board, which is electrically connected to the drive motor. The cable module is arranged in the axial extension of the drive motor in a section between the drive motor and the joint part of the drive joint that is axially fixed relative to the drive motor in a common housing section. The invention relates to a particularly compact design of a drive device for adjusting an adjusting element of a motor vehicle. However, it is a challenge to establish the connection between the joint element and the cable module, in particular the cable module cover of the cable module, as simply and reliably as possible. For the known drive unit, the joint part is thus introduced radially into the cable module cover and is connected axially fixedly thereto. The axially fixed connection must also withstand forces, in particular tensile forces, which may occur, for example, if the user manually actuates, in particular opens, the adjusting element with excessive force. It is also desirable to manufacture the unit consisting of the joint part and the cable module cover from as low a cost material as possible.

Disclosure of Invention

The problem of the invention is to design and improve the known drive unit in such a way that it can be produced as simply and cost-effectively as possible.

The above-mentioned problem is solved in a drive unit having the features of the preamble of claim 1 by the features of the characterizing part of claim 1.

Important is the principle consideration of: the cable module or its cable module cover for connecting the cable module to the drive unit is designed, on the one hand, and the joint part of the drive connection on the cable module side is designed, on the other hand, in such a way that the two components, after joining, engage one another during assembly in such a way that a form fit is present in the axial direction. In order to connect the cable module or the cable module cover to the joint element in an axially fixed manner, only an assembly movement of the joint element relative to the cable module is therefore required in the drive unit according to the disclosure, wherein this assembly movement at the same time already produces an axially fixed form fit. The provision of a means for establishing an axially fixed connection between the two components beyond the assembly movement of the joint part relative to the cable module can thereby be dispensed with more easily. In particular, it is not absolutely necessary that the joint part be connected to the cable module in a material-locking manner, for example by means of an expensive, high-strength and high-temperature-resistant adhesive or by means of a particularly costly welding, in order to produce a particularly reliable axial fastening. However, it is also not to be excluded that in the proposed drive unit, an additional, materially locked connection is also provided between the joint part and the cable module.

Providing the articulation on the one hand and the cable module on the other hand separately according to the proposed arrangement also offers the advantage that: a material different from the material of the articulation piece, in particular a lower-cost material, is used for the cable module cover. As will be explained further below, the material of the cable module cover can have a lower temperature resistance and/or tensile strength than the material of the joint.

In detail, it is proposed that, during assembly of the drive unit, the engagement section of the joint element and the corresponding counter engagement section of the cable module cover can be engaged in an assembly movement such that, in the assembled state, the engagement section and the counter engagement section are axially fixedly engaged into one another.

The fitting movement is specified in claim 2 as follows: the assembly movement preferably comprises or is at least one component which is orthogonal, in particular radial, with respect to the geometric drive axis. The joint element and the cable module are thus preferably joined during assembly in a direction that is angled relative to the geometric drive axis. In this way, not only can the axially fixed connection be established particularly easily, but in particular, this engagement of the two components also causes a torsion lock to be established between them.

In claim 3, the fitting segments and corresponding mating fitting segments are defined in more detail. One of them is thus a receiving portion into which the respective other is pushed. By pushing in, then at least an axial form-locking is produced, by: the receiving portion forms a undercut. Furthermore, the mentioned torsion lock state can also be established by the push-in.

Claims 4 and 5 relate to improvements in that: the fitting section and the mating fitting section, and thus the joint part and the cable module cover, are fixed relative to one another such that the two components cannot be moved apart from one another in the assembled state. Such a fastening can be effected by means of a snap-lock (claim 4) and/or by means of pushing a particularly tubular housing part onto the cable module cover (claim 5). The housing part is particularly preferably part of the drive housing and in particular forms an outer housing tube or, if appropriate, an inner housing tube of the telescopic drive housing.

Claim 6 defines different embodiments of the particularly tubular housing part. The housing part can hereby be part of a drive housing of the drive, but also of a drive unit housing which is designed to receive at least the drive motor and the cable module. Such a drive unit housing is also referred to as a drive sleeve. Unlike the drive unit housing, the drive housing additionally accommodates a feed gear of the drive, for example a screw-screw nut gear. The housing part of the drive unit housing and/or the housing part of the drive device housing is preferably connected in an axially fixed manner to the cable module cover.

According to a preferred embodiment according to claim 7, the joint part has, in addition to the engagement section, a bearing section which is supported in the final assembled state on the motor vehicle-side counterpart joint part. The engagement section and the support section are connected to one another, in particular integrally, by a connecting section. The support section is configured, for example, as a spherical seat.

The material preferred for the cable module cover and/or the joint part is specified in claim 8.

According to a particularly preferred embodiment of claim 9, the cable module cover is formed in one piece or in multiple pieces, in particular in two pieces. The cable module cover thus has at least two, preferably exactly two individual covers which are connected to one another during assembly and then together form the cable module cover.

According to a likewise preferred embodiment of claim 10, the cable module cover has a housing closure and a cable coupling.

The housing closure and the cable coupling of the cable module cover are then preferably joined in an assembly movement during assembly (claim 11), which can take place at an angle, in particular orthogonally, but also parallel, to the geometric drive axis.

Claims 12 and 13 relate to the possibility that: the housing closure and the cable coupling, and thus the at least two individual components of the cable module cover, are fixed relative to one another such that they cannot be moved apart from one another in the assembled state. Such a fastening can be effected by means of a snap-lock (claim 12) and/or by means of pushing one of the, in particular tubular, housing parts onto the unit formed by the housing closure and the cable connection (claim 13). It is particularly preferred that such a fastening function is caused by the housing part of the drive housing, in particular by an outer housing tube or, if appropriate, an inner housing tube of the telescopic drive housing. Additionally or alternatively, such a fastening function is caused by the housing part of the drive unit housing.

According to a likewise preferred embodiment according to claim 14, the electrical contact between the conductors of the cable module and the drive motor and/or the motor circuit board is achieved by an assembly movement of the cable coupling relative to the housing closure. In addition or alternatively, by means of this assembly movement, it is also possible to position the motion sensor fastened to the cable coupling, in particular the hall sensor, relative to the housing closure in such a way that the motion sensor is in the range of action of the magnet on the motor shaft of the drive motor in the assembled state. This ensures a particularly simple production of the drive unit and thus of the entire drive device.

A particularly preferred possible variant of the connection between the cable module cover and the joint part and/or between the cable coupling part and the housing closure part is the subject matter of claim 15.

Claims 16 to 18 relate to designs in which the one or more wires can be clamped in the wire lead-through in a simple manner during assembly and can be fastened to the cable module cover in this way. The filler for axially fastening the one or more wires to the cable module cover can thus be dispensed with, whereby costs can be saved and at the same time assembly can be simplified.

According to a further refinement according to claim 19, which is independent, a drive unit for a drive, in particular a screw drive, is claimed for adjusting an adjusting element of a motor vehicle, wherein the drive unit has: an electric drive motor with a motor housing; a cable module having a motor circuit board electrically connected to the drive motor and having a cable module cover into which one or more wires for electrical connection with the drive motor and motor circuit board are guided; at least one, in particular tubular, housing part which is connected axially fixedly to the cable module cover with respect to a geometric drive axis; and an articulation element which forms a first drive joint together with a counterpart articulation element on the motor vehicle side. In detail, it is proposed here that the cable module cover has a housing closure and a cable coupling, wherein the particularly tubular housing part is connected axially fixedly to the housing closure and the housing closure is wire-free, in particular in the unassembled state, and the one or more wires for the electrical connection to the drive motor and the motor circuit board are guided into the cable coupling, in particular already in the unassembled state, and that the housing closure can engage with the cable coupling in an assembly movement, which comprises or is a movement having a radial and/or parallel component with respect to the geometric drive axis, when the drive unit is assembled.

In detail, it is proposed herein,

Detailed Description

The drive unit 1 shown in the drawing is a component of the drive 2, here a screw drive, for adjusting an adjusting element 3 of the motor vehicle. The adjusting element 3 is here and preferably a back cover plate. All explanations concerning the tailgate apply here also to all other types of adjusting elements 3 of the motor vehicle. Reference may be made in this respect to the exemplary enumeration in the opening part of the description.

The drive 2 is used to adjust the tailgate. For this purpose, the drive device 2 is articulated on the one hand on the motor vehicle body and on the other hand on the adjusting element 3. The drive 2 here and preferably generates a linear drive movement along the geometric drive axis 4, so that the adjusting element 3 can be adjusted between a closed position and an open position shown in fig. 1. This adjustment is carried out by means of an electric drive motor 5 which, as will be explained below, generates a drive force which causes an adjustment of the adjusting element 3.

The drive motor 5 of the drive unit 1 has its own motor housing 5a, which is arranged in a drive unit housing, also referred to as a drive sleeve, which is shown in fig. 2 a) and 2 b) without being cut in the upper section of the drive device 2.

The drive unit 1 here and preferably also has one or more further drive unit components, such as an intermediate gear, for example a planetary gear, a brake, a coupling, etc., in such a way that they are arranged behind the drive motor 5 in terms of drive technology, wherein the drive unit components can in particular be arranged along the geometric drive axis 4 along with the drive motor 5 in each case likewise in the drive unit housing.

Furthermore, a feed gear 6, which is explained in more detail in the drive technology, is arranged downstream of the drive unit 1. The feed gear 6 is arranged together with at least the drive motor 5, in particular the entire drive unit 1, in a common drive housing of the drive 2, which is formed here and preferably telescopically and in particular in a tubular manner. For this purpose, the drive housing has an outer, in particular tubular housing part 2a and an inner, in particular tubular housing part 2b. The term "telescopic" in this respect means that the outer housing part 2a and the inner housing part 2b can be moved relative to one another in the axial direction, wherein the inner housing part 2b is guided in the outer housing part 2 a.

"axial" always refers here to the direction of the geometric drive axis 4. Accordingly, "radial" refers to a direction orthogonal thereto.

Furthermore, as shown in the views in fig. 3 to 5, the drive unit 1 has a cable module 7 with a motor circuit board 8, which is electrically connected to the drive motor 5. The drive unit housing of the drive unit 1 is also used here to receive a cable module 7.

The concept "motor circuit board" should be understood broadly herein. It includes not only a circuit board composed of a single layer but also a circuit board composed of multiple layers. It also includes rigid, flexible and rigid-flexible circuit boards. The motor circuit board 8 generally has a conductor circuit and electrical and/or electronic components in the above-described sense. Such a motor circuit board 8 can be used for controlling the drive motor 5 and/or other components of the drive unit 1 and/or of the drive device 2.

The cable module 7 has a cable module cover 9 into which one or more wires 10 for electrical connection with the drive motor 5 and the motor circuit board 8 are led from outside the drive unit 1. In addition, the cable module 7 has, for fixing the motor circuit board 8, a circuit board holder as a lower part 11 on the drive motor side, which is axially located between the drive motor 5 and the cable module cover 9 and engages with the cable module cover 9 in the axial direction during assembly. The cable module cover 9 and the lower part 11 are then in particular in contact with one another and/or are fixed relative to one another in the axial direction and in particular also in the radial direction. Furthermore, the motor circuit board 8 can be fixed in relation to the cable module 7 on the one hand in the radial direction and on the other hand in the axial direction, in particular in both directions, by means of the lower part 11 of the cable module 7. The lower part 11 is arranged here in an axial section of the drive unit housing, which is axially between the drive motor 5 and the cable module cover 9.

At least one, in particular tubular, housing part 1a, 2a, which, as will be explained further below, can be part of a drive unit housing or a drive device housing, is connected to the cable module cover 9 in an axially fixed manner with respect to the geometric drive axis 4. The respective housing part 1a, 2a acts directly on the cable module cover 9. Typically, the cable module cover 9 can be inserted into the respective housing part 1a, 2a, but alternatively can also be inserted onto the housing part.

The drive unit 1 further has a joint part 12 which, together with a corresponding motor-vehicle-side counterpart joint part 13, forms a first drive connection 14a of the drive device 2. This first drive connection is shown in fig. 2 at the upper end of the drive 2. The second drive connection 14b, which is formed in a corresponding manner, is located at the opposite lower end.

The cable module cover 9 is preferably a component which seals the respective housing part 1a, 2a axially, in particular in a sealing manner, relative to the joint part 12.

As shown in fig. 3 to 5, the joint part 12 has a fitting section 15, and the cable module cover 9 has a corresponding mating fitting section 16.

It is now important that, in the assembly of the drive unit 1, the engagement section 15 of the joint part 12 and the corresponding counter engagement section 16 of the cable module cover 9 can be engaged in an assembly movement in such a way that, in the assembled state, the engagement section 15 and the counter engagement section 16 are axially fixedly engaged into one another. Here, the fitting movement refers to a movement necessary for the purpose of fitting.

This particular embodiment of the drive unit 1 shown here allows an axially fixed connection to be established between the cable module 7 and the joint part 12 in a simple manner. Furthermore, there are viable solutions that are: the cable module cover 9 and the joint member 12 are provided which are made of different materials, whereby the cost of the drive unit 1 can be reduced.

In detail, it is here and preferably now arranged such that the assembly movement which engages the mating engagement section 15 with the counter engagement section 16 comprises or is a movement having a component which is radial with respect to the geometric drive axis 4. The movement can also be a movement directed obliquely to the geometric drive axis 4. It is important here, however, that an axial form fit exists between the cable module cover 9 and the joint part 12 in the assembled state. In the embodiment shown here, the arrangement is such that the assembly movement comprises or is a purely radial movement relative to the geometric drive axis 4.

Furthermore, the assembly movement which engages the mating fitting section 16 with the fitting section 15 is a linear, in particular purely linear movement.

As further shown in fig. 3 to 5, the fitting section 15 is pushed into a receptacle in the cable module cover 9, which receptacle forms a mating fitting section 16. In principle, according to an alternative embodiment, not shown here, it is also conceivable for the mating fitting section 16 to be pushed into a receptacle in the joint part 12, which then forms the fitting section 15.

Furthermore, it is provided here and preferably that the mating fitting section 15 and the mating fitting section 16, in particular their shape and/or material, are designed such that they form a predetermined breaking point in the engaged state. The engagement section 15 is formed in a substantially plate-shaped manner, while the mating engagement section 16 forms a push-in groove. The mating fitting section 16 forms a undercut for the fitting section 15 in the axial direction, so that an axial form fit is established. If, for example, a predetermined tensile force between the cable module cover 9 and the joint part 12 is exceeded later in the event of misuse, the connection between the mating section 15 of the joint part 12 and the mating section 16 of the cable module cover 9 breaks in the sense of a predetermined breaking point, so that, later, the joint part 12 remains connected to the motor vehicle-side mating joint part 13 and the cable module cover 9 remains connected to the drive unit 1 or the drive device 2. In this way further damage of the drive unit 1 or the drive device 2 is prevented. The abrupt loosening of the helical compression springs, which in this case may be located in the drive device 2 and which pre-tension the drive connections 14a, 14b relative to one another, is also prevented, which may lead to injury to the user.

Here and preferably further, the mating fitting section 16 and the fitting section 15 joined thereto are arranged in such a way that they are fixed relative to one another in the radial direction and in particular also in the axial direction. In the assembled state, the engagement section 15 and the mating engagement section 16 are preferably locked to one another in the radial direction. For this purpose, the outer contour of the plate-shaped engagement section 15 and the corresponding inner contour of the mating engagement section 16 are shaped so as to be lockable to one another in a corresponding manner, for example, as is shown in fig. 3 at the top right.

As a supplement or alternative, as also shown in fig. 3, the particularly tubular housing part 2a or one of the particularly tubular housing parts 1a, 2a can fix the engagement section 15 and the mating engagement section 16 engaged therewith relative to one another in the radial direction in the assembled state, so that the engagement section 15 and the mating engagement section 16 can no longer then be moved apart from one another in the radial direction. Here and preferably in this case, it is provided that the respective housing part 2a surrounds the cable module cover 9 radially at least in an axial section and covers it radially outwards and secures the fitting section 15.

During assembly, the fitting section 15 is first of all engaged with the mating fitting section 16 and the corresponding housing part 2a is then pushed onto the cable module cover 9 in such a way that the housing part 2a covers the fitting section 15 radially outwards. The cable module cover 9 and the motor-side lower part 11 of the cable module 7 are also fixed relative to one another in the axial direction and in particular also in the radial direction, here and preferably by the housing part 1 a.

The particularly tubular housing part 1a or one of the particularly tubular housing parts 1a, 2a here and preferably forms at least part of a drive unit housing. The housing part 1a forms a substantially cylindrical housing of the drive unit housing. Furthermore, the particularly tubular housing part 2a or one of the particularly tubular housing parts 1a, 2a forms at least part of a drive housing of the drive 2. The housing part 2a forms an upper part of the drive housing, wherein a further housing part 2b of the drive housing is guided telescopically in the housing part 2 a. The housing parts 2a, 2b are here embodied in particular as housing tubes.

The drive housing of the drive 2 is suitable for receiving the above-described feed gear 6 in addition to the drive motor 5 and the cable module 7, due to the two telescopic housing parts 2a, 2 b. The feed gear here and preferably as a screw-screw nut gear has a screw 17 which is coupled to the drive motor 5 in terms of drive technology and a screw nut 18 which engages with it in a manner which is conventional per se. The threaded rod 17 is axially fixed relative to the first drive connection 14a and the threaded rod nut 18 is axially fixed relative to the second drive connection 14b, so that the first drive connection 14a and the second drive connection 14b can be moved linearly relative to one another when the feed gear 6 is actuated, as already explained at the outset.

It should be emphasized that the housing part 2a forming part of the drive housing of the drive 2 is here a housing part which fixes the mating fitting section 16 and the fitting section 15 relative to one another. In principle, however, in an alternative embodiment not shown here, it is also conceivable that the housing part 1a, which fixes in particular the cable module cover 9 and the lower part 11 axially relative to one another, also fixes the mating fitting section 16 and the fitting section 15 relative to one another.

Fig. 3 also shows that the engagement section 15 is connected via a connection section 19 of the joint part 12 to a bearing section 20 of the joint part 12, which is mounted on the motor vehicle-side counterpart joint part 13 in the final assembly state. The bearing section 20 is formed here and preferably as a spherical seat which forms a ball joint with a corresponding counterpart of the motor vehicle-side counterpart joint 13. The term "final assembled state" refers here to a state in which the drive device 2 is mounted on the motor vehicle as specified. In this case, it is particularly preferred that the fitting section 15, the connecting section 19 and/or the support section 20 are integrally formed together.

In this case and preferably in addition, it is provided that the cable module cover 9 is made of plastic and/or the joint part 12 is made of plastic or metal. Preferably, the cable module cover 9 has a lower temperature resistance and/or a lower tensile strength than the joint part 12. Such a material is less costly than a high strength, high temperature resistant material such as that preferably provided for the articular component 12. The joint part 12 is made of polyamide or steel, for example. The joint part 12 has, for example, a temperature resistance (so-called short-term service temperature) of more than 180 ℃, preferably more than 200 ℃, more preferably more than 220 ℃ and/or a tensile strength of more than 120MPa, preferably more than 150MPa, more preferably more than 180 MPa. The cable module cover 9 is made of, for example, POM (polyoxymethylene). The cable module cover 9 has, for example, a temperature resistance between 110 ℃ and 170 ℃, preferably between 120 ℃ and 160 ℃, further preferably between 130 ℃ and 150 ℃ and/or a tensile strength between 40MPa and 90MPa, preferably between 50MPa and 80MPa, further preferably between 60MPa and 70 MPa.

The explanation thus far first relates to the cable module cover 9 constructed in one piece (fig. 3). In principle, however, it is also conceivable to construct the cable module cover 9 in multiple parts, in particular in two parts (fig. 4 and 5), as will be described in more detail below.

As shown in the exemplary embodiments of fig. 4 and 5, the cable module cover 9 here and preferably has a housing closure 21 and a cable coupling 22, wherein the particularly tubular housing parts 1a, 2a are connected axially fixedly to the housing closure and the housing closure is wire-free, in particular in the uninstalled state, and the one or more wires 10 for the electrical connection to the drive motor 5 and the motor circuit board 8 are guided from outside the drive unit 1 into the cable coupling, in particular already in the uninstalled state. The "uninstalled state" is here a state before the drive unit 1 is assembled and in particular before the housing closure 21 and the cable coupling 22 engage one another. The concept "leadless" means that the corresponding component has no electrical leads. The housing closure 21 and the cable coupling 22 are each formed in a dimensionally stable manner, i.e. do not deform or in any case do not significantly deform when subjected to a defined load.

During assembly of the drive unit 1, the housing closure 21 can now be engaged with the cable coupling 22 and more precisely in an assembly movement which comprises or is a movement having a radial and/or parallel component relative to the geometric drive axis 4, as described. Here and preferably, it is provided that the assembly movement comprises either a purely radial movement relative to the geometric drive axis 4 (fig. 4) or a purely parallel movement relative to the geometric drive axis 4 (fig. 5 b)) or a movement directed obliquely relative to the geometric drive axis 4 (fig. 5 d)).

The corresponding assembly movement in particular comprises or consists of a linear movement, preferably a purely linear movement.

In the assembled state, the housing closure 21 and the cable coupling 22 are in particular rotationally locked relative to one another, which is preferably achieved only by engagement in the assembly movement.

The cable coupling 22 is pushed into the housing closure 22, in particular into a receptacle forming a mating fitting section, in particular with the clip 23, here with the latching lugs 24. In an alternative embodiment not shown here, it can also be provided that the housing closure 21 is pushed into the cable coupling 22, in particular into the receptacle forming the mating fitting section, in particular with the fitting section.

In this case and preferably also, the arrangement is such that, before the cable connection 22 is joined to the housing closure 21, the motor circuit board 8 is first associated with the drive-motor-side lower part 11 and then joined to the housing closure 21. However, it is also conceivable to first engage the cable coupling 22 with the housing closure 21 and then to engage the lower drive-motor-side part 11 provided with the motor circuit board 8 with the housing closure 21.

Here and preferably the lower part 11 and the housing closure 21 are in contact after engagement. In addition or alternatively, the lower part 11 and the housing closure 21 are fixed relative to one another in the axial direction and in particular also in the radial direction, in particular by the housing part 1 a.

The housing closure 21 and the cable coupling 22 which engages with it are fixed relative to one another in the radial direction and/or in the axial direction. The arrangement is preferably such that in the assembled state the cable connector 22 and the housing closure 21 are locked to one another, in particular in the radial direction and/or in the axial direction.

In addition or as an alternative, it can be provided that the in particular tubular housing part 2a or one of the in particular tubular housing parts 1a, 2a, in the assembled state, secures the cable coupling 22 and the housing closure 21 joined thereto relative to one another in the radial direction. Here and preferably, the arrangement is such that the respective housing part 2a surrounds and thereby fixes the housing closure 21 and the cable coupling 22 radially at least in the axial section.

During assembly, the cable coupling 22 is first engaged with the housing closure 21 and the corresponding housing part 2a is then pushed onto the cable module cover 9 in such a way that the housing part 2a covers the cable coupling 22 and the housing closure 21 radially outwards.

The arrangement is preferably such that the housing part 2a forming part of the drive housing of the drive 2 is a housing part which fixes the cable coupling 22 and the housing closure 21 relative to one another. In principle, however, according to an alternative embodiment not shown here, the other housing part 1a can also assume this fastening function. The housing part 1a forming part of the drive unit housing here fixes at least the housing closure 21 and the lower part 11 relative to one another.

In order to simplify the assembly, it is here and preferably also provided that the electrical contact of the one or more wires 10 with the drive motor 5 and/or the motor circuit board 8 takes place by means of an assembly movement of the cable coupling 22 relative to the housing closure 21. Each wire 10 thus has an electrical connection which is electrically connected by an assembly movement to a corresponding electrical connection of the drive motor 5 and/or the motor circuit board 8.

As an addition or alternative, it can also be provided here that, by means of an assembly movement of the cable coupling 22 relative to the housing closure 21, at least one motion sensor 25, in particular a hall sensor, fastened to the cable coupling 22 is placed in a position relative to the housing closure 21 in which the motion sensor 25 is in the assembled state within the range of action of at least one magnet 26 fastened to the motor shaft of the drive motor 5. The motion sensor 25 is shown in fig. 4 as an optional component in dashed lines.

A particularly preferred possibility for connecting the individual components will now be discussed. The connection between the cable module cover 9 and the joint part 12 and/or the connection between the cable coupling 22 and the housing closure 21 is thus a form-locking and/or material-locking connection relative to the direction of the assembly movement. A latching connection is preferably provided as a form-locking connection. As a material-locking connection, an adhesive or welded connection, in particular a laser welded connection, is preferably provided. The above description applies, in addition or as an alternative, also to the connection between the cable module cover 9 and the lower drive motor-side part 11.

In the embodiment shown in fig. 6 a) and b) on the one hand and in fig. 6 c) and d) on the other hand, the cable module cover 9 is each formed in multiple parts and is assembled from the housing closure 21 and the cable coupling 22 in the assembled state. The embodiment shown in fig. 6 a) and b) corresponds in terms of its construction to the embodiment shown in fig. 4 a) and b), except for the features explained below. The embodiment shown in fig. 6 c) and d) corresponds in terms of its construction to the embodiment shown in fig. 5 a) and b), except for the features explained below. However, the embodiments shown in fig. 6 a) to d) should not be construed as limiting. Rather, the additional features described below can also be provided in all other previously described embodiments, in particular also having a one-piece cable module cover 9.

In the embodiment shown in fig. 6 c) and d), it is provided that the cable module cover 9, and more precisely the cable coupling 22 of the cable module cover 9 described here and preferably in several parts, has a wire lead-through 27, which forms a through opening. One or more wires 10 are guided through the wire lead 27. The arrangement is such that the wire lead-through 27 has a particularly groove-shaped material recess 28 which in the assembled state is directed toward the joint part 12 and/or the fitting section 15, and the joint part 12 and/or the fitting section 15 as in the present case has a clamping element 29 which in the assembled state is directed toward the cable module cover 9. The clamping element 29 can be introduced at least in sections into the material recess 28 in the region of the assembly movement of the joint part 12 relative to the cable module cover 9 and thus relative to the cable connector 22, in such a way that the one or more wires 10 are held in the wire guide 27. It is then not possible to pull one or more wires 10 out of the cable module cover 9 or, in the process, out of the cable coupling 22. Furthermore, the one or more wires 10 do not need to be fastened to the cable module cover 9 or the cable coupling 22 in an additional manufacturing step, for example by means of a filler. In this way, manufacturing can be simplified and cost savings achieved.

As shown in fig. 6 d), the cable coupling 22 has a wire lead-through 27, which forms a through opening for the lead-through of one or more wires 10, as described above. In an alternative embodiment, not shown here, the cable module cover 9 can also be a one-piece cable module cover 9, which then has a wire lead-through 27 forming a feedthrough. In the latter case, it is then preferably arranged such that the wire guide 27 has a particularly groove-shaped material recess 28 which in the assembled state is directed toward the joint part 12 and/or the fitting section 15, the joint part 12 and/or the fitting section 15 having a clamping element 29 which in the assembled state is directed toward the cable module cover 9, and the clamping element 29 can be introduced at least in sections into the material recess 28 in the range of the assembly movement of the joint part 12 relative to the cable module cover 9, such that the one or more wires 10 are held in the wire guide 27.

In the embodiment shown in fig. 6 a) and b), the arrangement is also such that the cable coupling 22 has a wire guide 27 forming a through opening, through which the one or more wires 10 are guided. However, unlike the embodiment described above and shown in fig. 6 c) and d), provision is made here for the wire lead-through 27 to have a material recess 28 which in the assembled state is directed toward the housing closure 21, in particular in the form of a groove, for the housing closure 21 to have a clamping element 29 which in the assembled state is directed toward the cable coupling 22, and for the clamping element 29 to be able to be introduced at least in sections into the material recess 28 in the range of the assembly movement of the housing closure 21 relative to the cable coupling 22, so that the one or more wires 10 are held in the wire lead-through 27.

As shown in fig. 6 for the embodiment there, the wire lead-through 27 preferably extends in the assembled state along the geometric drive axis 4 substantially in the axial direction. The material recess 28 and the clamping element 29 here and preferably each extend transversely, in particular perpendicularly, to the geometric drive axis 4.

In the exemplary embodiment illustrated in fig. 6 and preferred in this connection, provision is made for the wire feedthrough 27 to have a geometric wire feedthrough axis 30, for the one or more wires 10 to be surrounded at least in sections by an insulating element 31, in particular in the form of a hose, in the circumferential direction, partially or completely, for at least one section of the insulating element 31 to be arranged within the wire feedthrough 27, and for the clamping element 29 to be applied to the one or more wires 10 in the assembled state by the insulating element 31 in such a way that the one or more wires 10 and the insulating element 31 are held on the wire feedthrough 27. The insulating element 31 can have any external cross-sectional profile, in particular circular and/or angular. Damage to the one or more wires 10 is prevented very effectively by the insulating element 31. At the same time, a particularly effective sealing of the drive unit 1 can be achieved thereby.

The "circumferential direction" is here and furthermore always associated with the wire lead-through axis 30.

Alternatively, in a further embodiment not shown here, it is also conceivable for the wire lead-through 27 to protrude with respect to the cable coupling 22 in addition in the axial direction, i.e. to form a partially or completely encircling flange. It is then preferably provided that the insulating element 31 surrounds the wire lead-through 27, i.e. the part forming the flange, at least in sections in the radial direction, either partially or completely. In this case, too, the arrangement is such that the wire feedthrough 27 has a geometric wire feedthrough axis 30, such that the one or more wires 10 are surrounded at least in sections by an insulating element 31, in particular in the form of a tube, in the circumferential direction, either partially or completely, and such that the clamping element 29 acts on the one or more wires 10 in the assembled state via the insulating element 31, so that the one or more wires 10 and the insulating element 31 are held on the wire feedthrough 27.

The clamping of the one or more wires 10 takes place here and preferably as shown in fig. 6 and in this connection preferably transversely, in particular perpendicularly, to the wire lead-through axis 30.

It is particularly advantageous if the insulating element 31 extends from the wire lead-through 27 into the sealed region of the motor vehicle body. In this way, the one or more wires can be effectively protected from external influences, such as, for example, moisture.
