Description

The invention relates to a device for connecting a rotatable component and a non-rotatable support component by means of a connecting part which passes through openings in the rotatable component and the non-rotatable support component. It further relates to a window regulator of a motor vehicle with such a connection between a cable or cable pulley deflection and a guide rail and a corresponding method for connecting the components. The rotatable component and the non-rotatable support component are understood in particular to mean a cable pulley deflection (deflection pulley) and a guide rail of a cable window lifter of a motor vehicle.

In the manufacture and assembly of adjusting devices for motor vehicles, a so-called stepped bolt with a tubular section is often provided in order to connect a first component and at the same time to serve as a rotatable bearing for the first component. The first component can be, for example, a gear element or a pulley, while the further component can be, for example, a bracket.

Such a device for the positive connection of a first rotatable component and a second rotationally fixed component by means of a connecting part which has at least one tubular section is, for example, from US Pat DE 44 17 279 C2 known. The connecting part extends through openings in the components and has at least two deformation regions which can be deformed by applying an axial force once. There is a rigid, not between the first deformation area and a second deformation area deformable section with a round cross section, which serves as a storage area for the first rotatable component. The first deformation region clamps the connecting part on the non-rotatable component, while the second deformation region axially fixes the first rotatable component on the connecting part.

From the DE 41 31 098 C2 it is known to connect a cable window lifter directly to an inner panel of a vehicle door by means of fastening means which are each arranged in the axis of rotation of a deflection roller. To hold a deflection roller, a slope bracket is equipped with a two-stage axle bolt, the larger stage of which rests on the bracket and is connected to it by rivets. The larger step of the axle bolt serves as the axial bearing of the deflection roller, which is axially fixed at the other end of the axle bolt by a locking ring. A central bore is formed in the axle bolt and is made to coincide with a bore arranged in the bracket. A screw is passed through the two bores and is screwed into a threaded hole in a body panel, an upper end face of the axle bolt serving as an abutment for the screw head. In one embodiment, the axle bolt and the bracket are connected with a tubular rivet, one end of which overlaps the inner shoulder of the two-stage bore and the other end of which overlaps the underside of the bracket.

From the DE 196 09 252 C1 A connection between a first and a second component, in particular of adjusting devices for motor vehicles, is known, wherein a fastening section of the first component extends through a recess of the second component. At least one of the two components consists of a plastically deformable material and has a material deformation by means of which the fastening section of the first component is positively fastened in the recess of the second component. The material deformation is in this case formed by a peeled material region which is provided on the first component and / or on the second component and is bent over from the peeled component to the respective other component.

From the DE 10 2008 060 183 A1 a module assembly for installation in a motor vehicle with a subframe for receiving functional components of a motor vehicle and with a window regulator assembly arranged on the subframe and with a deflection unit of the window regulator assembly for deflecting a flexible traction means of the window regulator assembly is known. The deflection unit has a support component of the deflection unit with two bearing areas for the storage of a deflection element, via which the flexible traction means is deflected. Between the bearing areas, the deflection element is mounted on the support component via the bearing element in such a way that a support section of the bearing element is mounted on each support area of the support component.

The invention has for its object to provide a particularly suitable device for connecting a rotatable component and a non-rotatable support member. The connection should be as torque-resistant as possible.

Furthermore, a suitable method for connecting the components is to be specified, preferably using a cold forming method, in particular radial rivets.

In particular, the device and the method should be suitable for establishing a reliable, in particular torque-resistant, connection between a cable deflection (deflection roller) and a guide rail in a window regulator of a motor vehicle. The connection should be able to reliably absorb a torque acting on this, in particular between 10Nm and 20Nm, preferably between 10Nm and 15Nm, without the connection being damaged.

With regard to the device, this object is achieved according to the invention with the features of claim 1 and with regard to the method with the features of claim 10. Advantageous refinements and developments are the subject of the dependent claims.

For this purpose, the device for connecting a rotatable component and a non-rotatable support component, in particular a cable pulley deflection (deflection pulley) and a guide rail of a cable window lifter of a motor vehicle, has a connecting part (connecting element) which extends through an opening of the rotatable component and an opening of the support component. The connecting part is expediently a two- or multi-stage collar bushing, in particular a hollow cylindrical stepped bolt, and is suitably designed with an internal thread. The connecting part can thus advantageously also serve as a screw nut for a fastening screw for holding the assembly formed from the rotatable component and the perforated disk and the non-rotatable support component and the connecting part on a superordinate support.

On the side of the carrier component opposite the rotatable component, a perforated disc with a disc opening (disc hole) penetrated by the connecting part at the end is arranged. The perforated disk has a first toothing on the disk side facing away from the non-rotatable support component. This is preferably arranged or provided in the region of the pane opening and there preferably on or in the opening edge.

Suitably as a result of a forming process, in particular a cold forming process, preferably a radial riveting process (radial riveting), an end (forming end) of the connecting part protruding from the disk opening of the perforated disk is locally plastically deformed in such a way that the material of the connecting part is inserted into this (first) toothing to produce a positive, in particular, a non-positive and positive connection between the perforated disc and the connecting part penetrates (flows).

The passage through the aligned openings of the components is expediently carried out by means of a first section of the connecting part, while a second section suitably only engages in the opening of the rotatable component, but does not penetrate it. For this purpose, a contact collar is expediently formed between the first and the second partial section, which on a partial or opening contour of the rotationally fixed carrier component is present. The outer diameter of the second section is therefore larger than that of the first component.

The connecting part suitably has a third section, the outer diameter of which is larger than that of the second section. As a result, a further contact collar of the connecting part is formed, by means of which it rests on a component or opening contour of the rotatable component on the component side facing away from the carrier component. Following the forming process of the connecting part, the rotatable component is thus held reliably and captively on the fixed support component. The second section here more suitably has an axial section length which is slightly greater than the axial opening depth (component thickness) of the rotatable component, so that it can rotate freely on the connecting part.

In an advantageous development, the disk opening of the perforated disk has a further (second) toothing on the disk side facing the non-rotatable support component, in particular again in the region of the opening edge. On the one hand, this development offers the advantage that when the perforated disk involved in the connection is installed, i. H. when the perforated disc is placed or placed on the forming end protruding from the opening of the carrier component, there is always one of the toothings in which the material of the connecting part - that is to say its forming end - can penetrate.

The first and suitably also the second toothing of the perforated disk is produced by a cutting or non-cutting process. Here, groove-like or bead-like recesses or depressions are made in the perforated disk. These recesses or tooth grooves preferably extend from the hole edge (opening edge) of the disk hole (the disk opening) in the radial and axial directions. At the edge of the hole, the teeth of the toothing are formed between the recesses (tooth grooves), the tooth tips of which suitably end or form at the edge of the hole.

The teeth can be provided along the circumference of the disk opening or disk hole edge in the same or different pitches. In addition, the toothing, d. H. whose teeth and / or tooth grooves are round, pointed or angular. The teeth can extend, for example, over about a third or up to half (axial) disk thickness of the perforated disk.

For example, the toothing can be wave-shaped with rounded teeth and / or tooth grooves. Also, for example, twelve or twenty tooth tips and tooth grooves can be arranged, in particular evenly, distributed on the edge of the pane opening. In this case, the tooth grooves can have triangular groove flanks which run in the radial direction - starting from the edge of the pane opening - at an acute angle or at right angles or also at an obtuse angle, for example at an angle between 90 ° and 100 °.

The groove flanks can also run axially obliquely in the direction of the central disk axis. In addition, the groove flanks can run parallel to the center axis of the disk. In the case of such toothing geometries, the groove base, which is offset radially from the edge of the disk opening, can have a rectangular shape with circular (arc-shaped) or rectilinear base edges in the circumferential or tangential direction in the manner of an Allen geometry (hexagon socket or polygonal shape).

A so-called Torx geometry (hexagon socket or polygonal shape) can also be provided and, like the hexagon geometry (hexagon socket or polygonal shape), can be useful, in particular with regard to the greatest possible torque absorption or strength of the connection between the perforated disc and the connecting part (stepped bolt). A conical geometry of the toothing is also suitable, especially if the toothing on both sides extends into the disk hole over approximately half the axial disk thickness.

If the material (the material) of the fixed (non-rotatable) support component is sufficiently soft, for example aluminum, the material of the support component can also penetrate (flow into) the (second) toothing which then faces it, so that there is a positive connection between the perforated disc and the support member. This further increases the strength of the connection, particularly when torque is applied. In other words, as a result of the forming process and / or by applying an axial pressing force to the perforated disk or to the carrier component through local plastic deformation, material of the carrier component penetrates into this second toothing in such a way that a positive connection, in particular a non-positive and positive connection, of the Perforated disc is made with the support member.

The connection is particularly advantageous for fastening a deflection roller to a guide rail of a cable window lifter of a motor vehicle. The connecting part, in particular in this assembly, the further components of which are the deflection roller, the perforated disk and the guide rail, is designed as a hollow cylindrical stepped bolt with an internal thread. As a result, the connecting part can also serve as a screw nut if a fastening screw with an external thread that is suitable for the internal thread is provided in order to expediently fasten the assembly to a door panel of a motor vehicle door.

In the method for producing such a connection between a rotatable component, in particular a pulley deflection (deflection pulley), and a non-rotatable support component, in particular a guide rail of a cable window lifter, a connecting part, in particular a stepped bolt, is passed through openings in the rotatable component and the non-rotatable support component, wherein a partial section with a forming end of the connecting part extends through the opening of the carrier component. A perforated disk is placed thereon, which has teeth on the disk side facing away from the carrier component, in particular in the area of the disk hole thereof. That from the disk hole (the disk opening) of the perforated disk and thus from this protruding forming end of the connecting part is formed, preferably by means of radial rivets as a cold forming process, the material of the forming end of the connecting part being introduced into the toothing of the perforated plate and thereby inserted Positive connection, in particular a positive and positive connection, is produced between the perforated disk and the connecting part.

The method is particularly suitable for producing the connection of a cable deflection and a guide rail of a window lifter, in particular cable window lifter, of a motor vehicle and / or for assembling such a window lifter. Such a window lifter has a cable or cable roller deflection which is connected to a guide rail by means of a connecting part, the connecting part passing through a (first) opening of the cable or cable roller deflection and a (second) opening of the guide rail, on which the cable or the pulley deflection on the opposite side of the guide rail, a perforated disk is arranged with a disk opening penetrated by the connecting part at the end, the perforated disk having a first toothing on the disk side facing away from the guide rail, in particular in the area of the disk opening, and wherein a shaping end of the perforated disk protruding from the disk opening The connecting part, in particular in the course of a cold forming or radial riveting process, is deformed in such a way that the material of the connecting part is in the first toothing of the perforated disk, in particular for producing a positive connection between the hole washer and the connecting part, has penetrated.

Corresponding parts are provided with the same reference oaks in all figures.

Fig. 1 shows a perspective exploded view of a device 1 for connecting a rotatable component 2 and a non-rotatable carrier component 3 by means of a connecting part (connecting element) 4, which is to pass through a first opening 5 of the rotatable component 2 and a second opening 6 of the carrier component 3. On the side of the carrier component 3 opposite the non-rotatable component 2, a perforated disc 7 with a disc opening (a disc hole) 8 is provided, which (which) should also be penetrated by the connecting part 4. The perforated disk 7 has a first toothing 10 on the disk side 9 facing away from the non-rotatable carrier component 3 in the area of the disk opening 8. A second set of teeth 11 is provided on the other disk side 12 facing the carrier component 3 and also there preferably arranged in the area of the pane opening 8. The toothings 10 and 11 are each introduced into the opening or hole edge 13 there.

The connecting part 4 is designed as a hollow cylindrical stepped bolt, which in the exemplary embodiment has an internal thread 14. The connecting part 4 has a first section 4a with a first outer diameter d ₁ . The connecting part 4 also has a second section 4b with a second outside diameter d ₂ , which is larger than the first outside diameter d _{1 of} the first section 4a. The connecting part 4 also has a third section 4c with a third diameter d ₃ , which in turn is larger than the outer diameter d _{2 of} the second section 4b.

The second section 4b forms a first annular contact contour 15 at the transition to the first section 4a. With this first contact contour 15, the connecting part 4, in the state inserted into the openings 5 and 6, reaches a first partial contour 16, which is formed by the opening edge 16 of the opening 6 of the fixed support component 4 as its partial contour, is supported in the connection produced (mounting state) so from there.

The third section 4c of the connecting part 4 forms a second annular contact contour 17. With this, the connecting part 4 lies in the connection or assembly state on a partial contour which is formed by an edge collar 18 of the rotatable component 3 surrounding the first opening 5.

In Fig. 1 a superordinate supporting part 19 is also shown - only in part. The support member 19 has a fourth opening 20 which is aligned with the openings 5, 6, 8 of the rotatable component 3 and the fixed component 4 and the perforated disc 7. In the final assembly state, a fastening screw 21 with a (suitable) external thread 22 corresponding to the internal thread 14 of the connecting part 4 passes through the openings 20, 8, 6 and 5 of the carrier 19 and the perforated disk 7 as well as the carrier component 6 and the rotatable component 2. The fastening screw 21 engages with the external thread 22 in a central through opening 23 of the connecting part 4 in order to there with the Internal thread 14 to be screwed. The assembly shown, comprising the rotatable component 2, the non-rotatable carrier component 3, the perforated disk 7 and the connecting part 4 is thus held on the superordinate carrier 19.

To establish the connection between the rotatable component 2 and the fixed support component 3, the perforated disk 7 and a shaping end 24 of the connecting part 4 are provided at its free end opposite the third section 4c serving as a contact collar 15. With this forming end 24, the connecting part 4 also engages through the perforated disk 7 in the connection and projects out of the perforated disk 7 in a pre-assembled state.

In the course of a forming process, in particular using radial rivets as a cold forming process, the forming end 24 is shaped on the disk side 9. Material W ( Fig. 6 ) of the connecting part 4 or its forming end 24 into the toothing 10 of the perforated disk 7. In this way, a reliable, positive connection between the connecting part 4 and the perforated disk 7 is produced. This fluid, and preferably also non-positive, connection is also safe and reliable in the event of an overtorque occurring in the course of screwing the fastening screw 21 to the connecting part 2, for example also at a torque of approximately 12 Nm.

The assembly state with the connection of the rotatable component 2 on the carrier component 3 by means of the connecting part 4 and the perforated disk 7 are shown in FIG 2 and 3 .

Fig. 2 shows a view of the connection with a view of the rotatable component 2. As can be seen, the rotatable component 2 is axially secured by the third section 4c of the connecting part 4 due to its abutment on the part contour 18.

Fig. 3 shows the connection from the opposite side with a view of the perforated disk 7 and the formed end 24 of the connecting part 4 formed there. The 4a to 4d show the perforated disc 7 in perspective view with a view of one disc side 9 or 12 and the toothing 10 or 11 introduced there in the area of the opening edge 13, the following explanations being directed to the disc side 9 and the toothing 10 there, but this also apply to the recognizable toothing 11 on the opposite side 12 of the disc. The toothing 10 is formed in the exemplary embodiment by different groove or bead shapes, which are referred to below as tooth grooves 25.

The tooth grooves 25 extend from the opening or hole edge 13 both radially outward (in the direction of the outer circumference of the perforated disk) and axially into the disk opening 8. Between these tooth grooves 25, the teeth 26 of the toothing 10 are formed, the tooth tips 27 of which, owing to the shape or geometry of the tooth notes 25, increasingly taper towards the edge of the hole 13 and virtually form it. On the opposite side of the disk 12, the second toothing 11 there is produced analogously. This prevents incorrect positioning of the perforated disk 7 during assembly. The toothings 10, 11 can also be produced by other and different geometries, for example by a wave-shaped geometry or by an internal polygonal shape (Torx geometry) or by an internal polygonal shape (hexagon geometry).

So they show Figures 4a and 4d angular geometries of the tooth tips 27, which are formed by triangular groove flanks of the tooth grooves 25, which run axially obliquely in the direction of the central disk axis M. The embodiment of the toothing 10, 11 according to Fig. 4a has twelve teeth 26 and tooth grooves 25, the groove flanks of which extend approximately at right angles or obtuse angles in the radial direction R. The embodiment of the toothing 10, 11 according to Fig. 4d has twenty teeth 26 and tooth grooves 25, the groove flanks of which extend at an acute angle in the radial direction R. The tooth grooves 25 of the toothings 10 and 11 each extend in the axial direction A over approximately one third of the thickness of the perforated disk 7.

The Figures 4b and 4c again show angular geometries of the tooth tips 27, which are formed by triangular groove flanks of the tooth grooves 25, which run axially obliquely in the direction of the central disk axis M. These embodiments of the toothing 10, 11 in turn have twelve teeth 26 and tooth grooves 25. Their groove flanks open in the radial direction R into a flat groove bottom, which according to the embodiment Fig. 4b in the circumferential direction in the manner of an inner polygon and in the embodiment according to Fig. 4c is rectangular in the manner of an internal polygon. The tooth grooves 25 of these toothings 10 and 11 also extend in the axial direction A each over about a third of the thickness of the perforated disk 7.

Fig. 5 shows the form-fitting connection due to the shaping of the shaping end 24 of the connecting part 4 on the disk side 9 of the perforated disk 7. As a result of the cold shaping by means of the preferably used radial riveting method, material W of the connecting part 2 or its shaping end 24 has penetrated into the tooth grooves 25 of the toothing 10 (Cold flow), so that the positive connection between the connecting part 4 and the perforated disk 7 and preferably also a non-positive connection of the perforated disk 7 with the rotationally fixed carrier component 3 is established.

If the material or the material of the carrier component 3 is sufficiently soft, for example aluminum, then its material also penetrates into the toothing 11 of the perforated disk 7. As a result, a positive connection is also established between the perforated disk 7 and the carrier component 3, preferably in addition to a non-positive connection. The penetration of the material W into the toothing 10 and / or in the tooth notes 25 thereof is illustrated Fig. 6 .

For forming by means of radial rivets in the cold forming process, the forming force always acts only on a partial surface of the forming end 24 through repeated, in particular elliptical and / or tumbling movement of an upper die 28. This results in a forming with inflow (penetration) of the material W des with relatively little effort Connecting part 4 causes in the teeth 10 or in the tooth grooves 25.

Fig. 7 shows the device 1 and the result of the method for producing the connection of a cable pulley deflection as a rotatable component 2 on a guide rail as a non-rotatable or fixed support component 3. An upper and a lower cable deflection roller, each as a rotatable component 2, and the guide rail as a non-rotatable support component 3 are part of a cable window lifter 29 of a motor vehicle.

The cable window lifter 29 furthermore comprises a driver 30, which is slidably guided on the guide rail with its function as a rail slider, serves to move (take along) a vehicle window (not shown) along the guide rail. An electric motor 31 with a coupled gear 32 drives a cable drum (not visible) on which a pull cable 33 is wound. The traction cable is guided via the cable deflections as rotatable components 2 to the driver 30 on which the vehicle window is held.

In the course of a rotary movement of the energized electric motor 31, the cable drum rotates in one of the directions of rotation, the traction cable 33 being wound up and unwound. As a result, the driver 30 attached to the traction cable 33 and thus the vehicle window pane are guided, for example, from a closed position into an open position. In the opposite direction of rotation, the driver 30 and thus the vehicle window are moved in the opposite direction by means of the pull cable 33 guided over the pulley deflections as rotatable component 2, and the vehicle window - in this example - is guided from the open to the closed position.

The claimed invention is not limited to the exemplary embodiments described above. Rather, other variants of the claimed invention can also be derived therefrom by the person skilled in the art within the scope of the disclosed claims without departing from the subject matter of the claimed invention. In particular, all of the individual features described in connection with the various exemplary embodiments are also part of the disclosed claims can also be combined in other ways without departing from the subject matter of the claimed invention.
