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. Between the first deformation area and a second deformation area there is a rigid, non-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 a torque acting on this, in particular between 10Nm and 20Nm, preferably between 10Nm and 15Nm, can reliably absorb without damaging the connection.

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 lies against a partial or opening contour of the rotationally fixed carrier component. 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 wavy with rounded teeth and / or Tooth grooves must be executed. 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. Here, the tooth grooves can have triangular groove flanks that 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 (material) of the fixed (non-rotatable) support component is sufficiently soft, for example aluminum, then the material of the support component can also penetrate (flow into) the (second) toothing that then faces it, so that there is also a positive fit between the perforated disc and the Carrier component is made. 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 a positive connection, in particular a force and Form fit, between the perforated disc and the connecting part is made.

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.

On the non-rotatable component 2nd opposite side of the support member 3rd is a perforated disc 7 with a disc opening (a disc hole) 8th provided which (which) of the connecting part 4th also to be dealt with. The perforated disc 7 points to that of the non-rotatable support member 3rd opposite side of the pane 9 in the area of the window opening 8th a first interlocking 10th on. A second interlocking 11 is on the other, the support member 3rd facing disc side 12th provided and there also preferably in the area of the window opening 8th arranged. The gears 10th and 11 are each in the opening or hole edge there 13 brought in.

The connecting part 4th is designed as a hollow cylindrical stepped bolt, which in the exemplary embodiment has an internal thread 14 having. The connecting part 4th has a first section 4a with a first outer diameter d ₁ . The connecting part 4th also has a second section 4b with a second outer diameter d ₂ , which is larger than the first outer diameter d _{1 of} the first section 4a . The connecting part 4th 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 at the transition to the first section 4a a first annular contact contour 15 out. With this first system contour 15 the connecting part arrives 4th im in the openings 5 and 6 inserted state to a first partial contour 16 from the opening edge 16 the opening 6 of the fixed support component 4th as its partial contour is formed, it is supported there in the connection produced (assembly state).

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

In 1 is also a superordinate supporting part 19th - only excerpts - shown. The support part 19th has a fourth opening 20th on which with the openings 5 , 6 , 8th of the rotatable component 3rd and the fixed component 4th and the perforated disc 7 flees. In the final assembly state, a fastening screw reaches through 21 with one to the internal thread 14 of the connecting part 4th corresponding (suitable) external thread 22 the openings 20th , 8th , 6 and 5 of the carrier 19th and the perforated disc 7 and the support member 6 and the rotatable component 2nd . The fastening screw 21 engages with their external thread 22 into a central through opening 23 of the connecting part 4th one to there with the internal thread 14 to be screwed. The assembly shown from the rotatable component 2nd , the non-rotatable support component 3rd , the perforated disc 7 and the connecting part 4th is thus on the parent carrier 19th held.

To establish the connection of the rotatable component 2nd with the fixed support component 3rd are the perforated disc 7 and a forming end 24th of the connecting part 4th on that, as an investment association 15 serving third section 4c opposite free ends provided. With this end of forming 24th passes through the connecting part 4th in the connection also the perforated disc 7 and protrudes from the perforated disc in a pre-assembled state 7 out.

In the course of a forming process, in particular using radial rivets as a cold forming process, becomes the forming end 24th on the disc side 9 reshaped. Material penetrates W ( 6 ) of the connecting part 4th or its forming end 24th in the gearing 10th the perforated disc 7 on. This is a reliable, positive connection of the connecting part 4th with the perforated disc 7 produced. This form-fitting, and preferably also non-positive connection is also in the course of screwing the fastening screw 21 with the connecting part 2nd over-torque, for example even at a torque of about 12 Nm, safely and reliably.

The assembly status with the connection of the rotatable component 2nd on the support component 3rd by means of the connecting part 4th and the perforated disc 7 show the 2nd and 3rd .

2nd shows a view of the connection with a view of the rotatable component 2nd forth. The rotatable component can be seen 2nd through the third section 4c of the connecting part 4th due to the fact that it rests on the partial contour 18th axially secured.

3rd shows the connection from the opposite side with a view of the perforated disc 7 and the formed end there 24th of the connecting part 4th .

The 4a to 4d show the perforated disc 7 in perspective view with a view of one side of the disc 9 or 12th and there in the area of the opening edge 13 introduced toothing 10th respectively. 11 , with the following explanations on the disc side 9 and the gearing there 10th are directed, but also for the recognizable gearing 11 on the opposite side of the disc 12th be valid. The gearing 10th is formed in the exemplary embodiment by different groove or bead shapes, which are subsequently called tooth grooves 25th are designated.

The tooth grooves 25th extend from the opening or hole edge 13 both radially outwards (in the direction of the outer circumference of the perforated disc) and axially into the disc opening 8th inside. Between these tooth grooves 25th are the teeth 26 the gearing 10th formed whose tooth tips 27 due to the shape or geometry of the tooth notes 25th tapers increasingly towards the edge of the hole 13 extend and form it. On the opposite side of the window 12th is analogous to the second toothing there 11 produced. This results in incorrect positioning of the perforated disc during assembly 7 avoided. The gears 10th , 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 4a and 4d angular tooth tip geometries 27 , which are characterized by triangular groove flanks of the tooth grooves 25th are formed, which extend axially obliquely in the direction of the central disc axis M. The embodiment of the toothing 10th , 11 according to 4a has twelve teeth 26 and tooth grooves 25th on, the groove flanks of which run approximately at right angles or obtuse angles in the radial direction R. The embodiment of the toothing 10th , 11 according to 4d has twenty teeth 26 and tooth grooves 25th on, whose groove flanks run at an acute angle in the radial direction R. The tooth grooves 25th the gears 10th and 11 extend in the axial direction A over about a third of the thickness of the perforated disk 7 .

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

5 shows the connection forming the positive connection as a result of the forming of the forming end 24th of the connecting part 4th on the disc side 9 the perforated disc 7 . As a result of the cold forming by means of the radial riveting method that is preferably used, material is W of the connecting part 2nd or its forming end 24th in the tooth grooves 25th the gearing 10th penetrated (cold flow), so that the positive connection between the connecting part 4th and the perforated disc 7 and preferably also a non-positive connection of the perforated disc 7 with the non-rotatable support component 3rd is made.

Is the material of the carrier component 3rd sufficiently soft, for example aluminum, so its material also penetrates the teeth 11 the perforated disc 7 on. This is also between the perforated disc 7 and the support member 3rd , preferably in addition to a non-positive connection, a positive connection is established. The penetration of the material W in the gearing 10th or in its tooth notes 25th illustrated 6 .

For forming by means of radial rivets in the cold forming process, the forming force only ever acts on a partial area of the forming end 24th by a repeated, in particular elliptical and / or tumbling motion of an upper die 28 . As a result, forming with inflowing (penetration) of the material takes place with relatively little effort W of the connecting part 4th in the gearing 10th or in its tooth grooves 25th causes.

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

The cable window lifter 29 also includes a driver 30th , which is slidably guided on the guide rail with its function as a rail slider, serves to move (take away) a vehicle window (not shown) along the guide rail. An electric motor 31 with coupled gear 32 drives an invisible rope drum on which a pull rope 33 is wound up. The pull rope is via the rope deflections as rotatable components 2nd to the driver 30th out on which the vehicle window is held.

In the course of a rotary movement of the energized electric motor 31 rotates the rope drum in one of the directions of rotation, whereby the pull rope 33 is wound up and unwound. As a result, the on the pull rope 33 attached carriers 30th and thus the vehicle window, for example, from a closed position to an open position. The driver becomes in the opposite direction of rotation 30th and thus the vehicle window by means of the rotatable component via the pulley deflections 2nd guided pull rope 33 move in the opposite direction and the vehicle window - in this example - is moved from the open to the closed position.
