Abstract
Description
Technical Field
[0001] The invention relates to a deflection device for a cable of a window regulator for a motor vehicle, comprising a cable roller for deflecting the cable and a support element for rotatably supporting the cable roller. The invention also relates to a window regulator for adjusting a window pane of a motor vehicle and a door module for a vehicle door. Background Art
[0002] A motor vehicle window lifter (hereinafter also referred to as a window lifter assembly) comprises a carrier component (carrier) and a guide device arranged thereon for guiding a flexible traction mechanism (cable). The guide device can transmit the adjustment torque (adjusting force) generated by the (electric motor-type) window lifter drive to the window pane to be adjusted via the guide device. The guide device is typically formed by a deflection mechanism and one or more guide rails, by means of which the cable is guided in an adjustment section in the adjustment direction of the window pane to be adjusted. The carrier component on which the guide device is accommodated can be a modular carrier that is installed in a motor vehicle door together with pre-assembled functional components, such as, in particular, components of the window lifter.
[0003] At least one follower or rail slider is fastened to a cable guided by a guide device, by means of which the window pane to be adjusted is connected to the cable. The follower is located on an adjustment section of the cable that extends along a guide rail extending in the adjustment direction and is longitudinally movable in the guide rail. The follower, the adjustment section of the cable, and the window pane to be adjusted are thus guided along the guide rail. When force is introduced into the cable by an associated adjustment drive, the window pane is adjusted via the follower along a longitudinally extending adjustment path, which is predetermined by the guidance of the follower and cable by the guide device.
[0004] During movement along an adjustment track, the follower of a so-called dual-track window lifter and the window pane to be adjusted move along an adjustment surface, which is thus predetermined or defined by the adjustment track. A deflection mechanism is provided to allow the cable, which is coupled to and exits the adjustment drive, to be guided along the guide rail in a targeted manner. This can be a deflection mechanism in the form of a roughly semicircular deflection element or deflection profile, or a cable roller rotatably mounted in the area of the guide rail or at the end of the guide rail.
[0005] WO 2018 / 224 415 A1 discloses a deflector element of this type, arranged on a carrier component of a window lifter assembly, that is secured against relative rotation. The deflector element has a guide channel for deflecting a cable in a guide plane that lies in or parallel to the xz plane in the typical vehicle coordinate system. The deflector element can essentially be constructed as a separate component and fastened to the carrier component. Polyarylether plastic is proposed as a material, but this material is very expensive. Furthermore, since the cable is typically made of commercially available steel, the deflector element wears due to numerous adjustment cycles and thus does not achieve the desired wear resistance. Furthermore, pressing the cable into the plastic carrier component can lead to acoustic disadvantages, particularly in the form of undesirable noise emissions.
[0006] Cable rollers, also known as deflection rollers, typically have a central hole through which they are connected to a guide rail or other load-bearing part of a cable window lifter using a rivet bolt (DE 198 55 011 C1) or a plug-in or stepped bolt (DE 20 2008 010 920 U1). Screw-on and clamping elements with a widened head are known from DE 20 2005 017 112 U1 as fastening and support elements for cable rollers. Such deflection devices are expensive because the fastening and support elements are required as additional components. Furthermore, particularly when fastening cable rollers to plastic supports, typical strength requirements, such as those in thermal creep tests (wrinkle storage tests), often cannot be met. Summary of the Invention
[0007] The object of the present invention is to provide a particularly suitable deflecting device for a cable of a window lifter or a window lifter assembly for a motor vehicle. In particular, the deflecting device should have as few components as possible and should allow for simple, preferably automated, assembly of the cable roller. Furthermore, a suitable window lifter or window lifter assembly having such a deflecting device and a suitable door module having such a window lifter (window lifter assembly) should be provided.
[0008] According to the invention, this object is achieved with respect to the deflection device by means of the features of claim 1, with respect to the window lifter or the window lifter assembly by means of the features of claim 9, and with respect to the door module by means of the features of claim 10. Advantageous embodiments, improvements, and variants are the subject matter of the dependent claims.
[0009] A deflecting device for deflecting a cable in a motor vehicle window regulator comprises a cable roller (deflecting roller) and a carrier (carrier component), as well as a carrier-side journal for rotatably supporting the cable roller. The carrier is preferably made of plastic and is therefore suitably a plastic part. The carrier can also be a guide rail, for example, made of steel or aluminum, and the journal can be a molded or extruded part of the guide rail or an associated bearing pin, for example, which engages with a door module or the like.
[0010] The cable roller (deflection roller) has a running groove for the cable and a central bearing opening. The annular cable roller is designed with an inner ring wall surrounding the central bearing opening and an outer ring wall with a circumferential running groove (cable groove or guide groove) for the cable.
[0011] The annular cable roller is connected to the shaft journal in a snap-fit manner. In other words, the cable roller is directly clipped or clamped onto the shaft journal. Suitably, an annular space, in particular a ribbed annular space, is formed between the inner and outer ring walls of the cable roller.
[0012] In one advantageous embodiment, the journal is a cylindrical or hollow-cylindrical shaped part of the carrier, that is, formed directly from the carrier material. Alternatively, the journal is a shaped or extruded part that subsequently forms the guide rail of the carrier, or a bearing pin assigned to the guide rail, which has a shaft and a head at the end of the shaft. The journal on the carrier side forms the physical bearing axis (rotation axis) of or for the cable roller.
[0013] The cable roller is expediently made of plastic, in particular a polymer, such as polyetheretherketone (PEEK), polyamide (PA), or polyoxymethylene (POM). In particular, an overmolded metal sleeve can be inserted, in particular pressed, into the central bearing opening of the cable roller. This allows for a particularly large inner diameter (bearing diameter) of the central bearing opening while simultaneously minimizing the use of material for the annular cable roller.
[0014] The inner diameter of the central bearing opening is at least two-thirds (2 / 3) of the outer diameter of the cable roller. Preferably, the ratio of the inner diameter of the inner ring wall of the cable roller to the outer diameter of the outer ring wall is less than one (1), in particular less than 0.9, preferably less than 0.8, and greater than 0.4, in particular greater than 0.5, preferably greater than 0.7.
[0015] According to a particularly advantageous embodiment of the cable roller, it has a number of circumferentially arranged, preferably evenly distributed, latching tongues. The latching tongues on the cable roller side are preferably formed on the inner wall of the cable roller ring. Particularly preferably, the latching tongues protrude axially beyond the inner wall of the ring and point radially inward, that is, toward the axis of rotation or bearing of the cable roller. An inner wall section is formed between the latching tongues, which, in the engaged state, rests against the axle journal when the cable roller establishes a snap-fit connection with the axle journal and forms a sliding bearing between the cable roller and the axle journal.
[0016] The cable roller-side latching tongues snap into or clip into corresponding latching grooves on the axle journal to establish the snap-on connection. During the snap-on connection, when the cable roller's latching tongues snap into or clip into the preferably circumferential latching grooves on the axle journal, the cable roller-side latching tongues assume their initial, normal position, which existed before the engagement. In other words, the cable roller-side latching tongues are in a normal position before the engagement process, are elastically bent radially out of the way during the engagement process to establish the snap-on connection, and return to their normal position during the snap-on connection. This ensures that the latching tongues do not rest against the axle journal in a spring-elastic manner with a specific compressive force and corresponding frictional forces during the snap-on connection. This prevents unwanted wear of the latching tongues or the axle journal and any resulting operating noise.
[0017] In one variant, the journal has a number of latching elements distributed around the circumference, in particular arranged in a crown-like manner, and the cable roller, in particular the inner ring wall of the cable roller, engages the latching elements from behind to produce the snap-in connection. Alternatively, radially outwardly directed latching elements are integrally formed onto the inner ring wall of the cable roller, and the latching elements engage in a preferably circumferential annular groove of the journal to produce the snap-in connection.
[0018] The cable roller advantageously has a mounting groove coaxial with the running groove, for example, a continuous, circumferential groove for threading the cable into the running groove. The mounting groove is advantageously formed by a number of partial abutment grooves. These are preferably arranged around the circumference of the annular cable roller, alternating with the locking tongues, i.e., adjacent to each of the locking tongues.
[0019] The assembly groove, in particular each abutment groove, is suitably formed into the outer ring wall or into the cable roller between the outer ring wall and the inner ring wall. When the cable is first introduced into the assembly groove during assembly, the abutment groove forms a localized receiving area for the cable. The diameter of the assembly groove is suitably smaller than the diameter of the running groove, which simplifies threading the cable onto the cable roller. A localized insertion area, arranged axially between the assembly groove and the running groove and where the assembly groove opens into the running groove, allows the cable to be automatically threaded into the running groove upon or during the initial rotational drive of the cable roller. During the cable threading process, the cable automatically tightens due to the increased diameter along the localized insertion area, thereby compensating for cable slack in the cable.
[0020] The deflection device is particularly suitable for window regulators or window regulator assemblies for adjusting a window pane of a motor vehicle, and also for door modules of vehicle doors, in which the window pane to be adjusted by means of the window regulator can be moved between an open position and a closed position. The window regulator for adjusting the window pane comprises a carrier or a carrier component and a (flexible) cable for transmitting an adjusting force for adjusting the window pane. The door module for a vehicle door comprises such a window regulator and is suitably mounted between a door outer skin (door panel) and a door inner cover (door trim).
[0021] The advantages achieved by the present invention are particularly that the deflection device is essentially only two-part and therefore has very few components. Furthermore, the cable roller can be assembled in a particularly simple and preferably automated manner. Furthermore, the cable and / or the running grooves of the cable roller experience little wear, and virtually no disturbing noise is generated between the cable and the cable roller. Furthermore, the cable roller support can be designed to be particularly flexible and optimized for sliding with a grease pocket. To this end, an annular groove for accommodating grease is suitably introduced into the shaft journal, in particular coaxially with the latching groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 A top view shows a window lift assembly 1 having a carrier component, hereinafter referred to as carrier 2, which is advantageously made of plastic and is therefore a plastic component. Two (substantially) parallel guide rails 3 are mounted on the carrier 2, on which a follower (track slide) 4 is displaceably guided. A window pane 5, indicated by dashed lines, is held on the follower 4. The follower 4 is connected to a cable 6 as a flexible traction mechanism, which is deflected multiple times and coupled to an electric motor-type adjustment drive 7.
[0036] As deflection devices 11, cable rollers (deflection rollers) 8 are provided (in the exemplary embodiment, at the upper rail ends of the guide rails 3), which are rotatably mounted on support-side journals 9. The journals 9 are preferably formed from the material of the support 2. In other words, the respective journal 9 is formed (shaped) from the support material itself as a cylindrical or hollow cylindrical shaped body.
[0037] In the exemplary embodiment, a semicircular, rotationally fixed deflecting element 10 is provided in the region of the lower rail end of the guide rail 3 , which deflecting element is preferably also formed from the material of the carrier 2 . Via these rotationally fixed deflecting elements 10 and the rotatably mounted cable roller 8 , the cable 6 is deflected from a cable section extending along the guide rail 3 into cable sections extending diagonally between the guide rails 3 and intersecting one another. The adjusting drive 6 is arranged in one of these diagonally aligned cable sections. Instead of the rotationally fixed deflecting element 10 , a rotatably mounted cable roller on the carrier side can also be provided in the region of the lower rail end of the guide rail 3 .
[0038] Figures 2 to 4 The deflection device 11 is shown in a pre-assembled state, in which the cable roller 8 is not yet engaged with the journal 9, and in an engaged state ( Figure 2 ), in the engaged state a snap-fit connection is established between the cable roller 8 and the journal 9 ( Figure 3 and Figure 4 In the snap-on connection, the cable roller 8 is clipped or snapped directly onto the journal 9. The deflection device 11 essentially consists solely of the cable roller 8 for deflecting the cable 6 of the window lifter 1 and the journal 9 on the carrier side, i.e., formed on the carrier 2, as a rotary bearing for the cable roller 8.
[0039] The cable roller 8 has a running groove 12 for the cable 6 and a central support opening 13. The cable roller 8 has a ring shape between a ring inner wall 14 and a ring outer wall 15 surrounding the central support opening 13. The circumferential running groove (cable groove or guide groove) 12 for the cable 6 is formed into the ring outer wall. An annular space 16 is formed between the ring inner wall 14 and the ring outer wall 15 of the cable roller 8. It is implemented as a rib (rib-shaped) in this embodiment. In other words, the cable roller 8 has a waisted cross-sectional shape in this embodiment, as shown in FIG. Figure 4 and Figure 6 However, the annular space 16 can also be omitted, that is to say filled approximately with plastic material, in particular the plastic material of the cable roller.
[0040] The journal 9 on the carrier side forms the physical bearing axis (rotation axis) 17 of the cable roller 8 and is formed from the carrier material as a hollow cylindrical molded part of the carrier 2. The journal 9 has a number of radial ribs 9c ( Figure 2 ).
[0041] As from Figures 2 to 6 As can be seen, the cable roller 8 has a certain number, in the exemplary embodiment six (6) locking tongues 18, which are evenly distributed around the circumference. These locking tongues 18 on the cable roller side are formed on the ring inner wall 14 of the cable roller 8. With reference to the bearing axis 17, the locking tongues 18 protrude axially from the ring inner wall 14, here also axially from the ring outer wall 15, and point radially inwards. Wall sections (inner wall sections or cable roller sections) 19 are formed between the locking tongues 18. In the engaged state after the cable roller 8 has established the snap connection, the wall sections rest on the journal 9 and, as a corresponding component of the ring inner wall 13, form a particularly low-friction sliding bearing between the cable roller 8 and the journal 9.
[0042] The cable roller-side latching tongue 18 latches or clamps into the corresponding (circumferential) latching groove 20 of the axle journal 9 and establishes the snap connection S ( Figure 4 ). During the establishment of the snap connection S, the spring-elastic latching tongues 18 are radially displaced. If the latching tongues 18 on the cable roller side of the cable roller 8 are clipped into the latching grooves 20 of the journal 9, they occupy the space again. Figure 2 and Figure 5 The normal position shown in . As a result, unwanted wear of the latching tongue 18 or the journal 9 and thus operating noise or disturbing noise are avoided.
[0043] The roller 8 is preferably made of plastic, such as a polymer. Polyetheretherketone (PEEK), polyoxymethylene (POM) and polyamide (PA) are particularly suitable.
[0044] As according to Figure 6 As can be seen from the sectional view of the cable roller 8, the inner diameter d of the cable roller 8 in the region of the central bearing opening 13 is i At least the outer diameter d of the cable roller 8 a In this embodiment, the inner diameter d of the cable roller 8 is two-thirds (2 / 3). i and outer diameter d a The ratio is between 0.7 and 0.75. The axial roller thickness D of the cable roller 8 including the axially protruding latching tongues 18 is the outer diameter d of the cable roller 8. a One fifth (1 / 5) to one quarter (1 / 4) of the inner diameter d of the cable roller 8 i About one third (1 / 3) of the
[0045] Figure 7 A variant of the deflection device 11 is shown in a simplified, fragmentary sectional view. In this embodiment, the journal 9 has a number of crown-shaped latching elements 18' uniformly distributed over its circumference. During the production of the snap-in connection S, the journal-side latching elements 18' are displaced radially inward relative to the bearing axis 17 and relative to the central bearing opening 13 of the cable roller 8, as indicated by the dashed lines. In the snap-in connection S, the journal-side latching elements 18' engage the cable roller 8. The journal-side latching elements 18' latch from behind onto a suitable surface of the cable roller 8 to secure it axially.
[0046] exist Figure 8 In a variant of the deflection device 11 which is simplified again and shown in a fragmentary sectional view, radially outwardly pointing latching elements 18" are integrally formed onto the cable roller 8 in the region of the central bearing opening 13 and thus onto the annular inner wall 14 of the cable roller 8. In a snap-fit connection, these latching elements engage in a preferably circumferential annular groove or latching groove 20' of the axle journal 9.
[0047] Figure 9 The cable roller 8 shown schematically in the figure has an assembly groove 21 coaxial with the running groove 12 for inserting the cable 6 into the running groove 12. In the embodiment, the assembly groove 21 is segmented and is formed by a number of abutment grooves 22, which are five in the embodiment. The abutment grooves 22 and therefore the assembly groove 21 are formed on the cable roller between the outer ring wall 14 and the inner ring wall 15 of the cable roller 8 (i.e., in the area of the annular space 16). The abutment grooves 22 are arranged between the locking tongues 18 and are therefore arranged adjacent to them. In other words, the abutment grooves 22 and the locking tongues 18 are arranged alternately on the circumference of the cable roller 8. When the cable 6 is first inserted into the assembly groove 21 during the assembly process, the abutment grooves 22 form a local receiving area for the cable 6.
[0048] The diameter of the mounting groove 21 is smaller than the diameter of the running groove 12 of the cable roller 8. This simplifies the insertion of the cable 6 onto the cable roller 8. A local insertion area 23, which is arranged axially between the mounting groove 21 and the running groove 12 on the circumference of the cable roller 8, leads from the mounting groove 21 into the running groove 12. This allows the cable 6 to be automatically inserted into the running groove 12. To this end, the cable roller 8 is driven in the direction of rotation. During the insertion of the cable 6, the cable 6 is tightened (stretched) along the local insertion area 23 due to the increase in diameter, and cable slack is removed from the cable 6.
[0049] Reference again Figure 4 An annular groove 24 (grease reservoir) for accommodating grease is introduced into the journal 9 coaxially with the latching groove 20. During the rotational movement of the cable roller 8, the grease penetrates between its running or bearing surface 25a and the running or bearing surface 25 of the journal 9. This creates a particularly low-friction sliding bearing between the cable roller 8 and the journal 9.
[0050] Figure 10 and Figure 11 Variants of the carrier and journal are shown in perspective or sectional views. The guide rail 3 serves as the carrier, and the journal is formed (provided) by the bolt head or bearing head 26a of a bearing bolt 26 having a bolt rod 26b. The bearing head 26a of the bolt-like journal 9 establishes a snap-fit connection with the annular cable roller 8, whose running groove 12 the cable 6 is guided.
[0051] The bearing bolts also serve in a suitable manner as engaging elements for fastening the guide rail 3 to a module, for example a door module, in particular when the carrier 2 and the guide rail 3 are separate components. The material of the guide rail 3 is expediently steel or aluminum.
[0052] In summary, the invention relates to a deflection device 11 for a cable 6 of a window lifter 1 for a motor vehicle, comprising a cable roller 8 with a circumferential running groove 12 and a central bearing opening 13 for the cable 6, a carrier 2 for the cable roller 8 and a carrier-side journal 9 for rotatably supporting the cable roller 8, wherein the annular cable roller 8 is engaged with the journal 9 in a snap-fit connection, in particular by means of an integrated latching or clamping element.
[0053] The claimed invention is not limited to the embodiments described above. Rather, those skilled in the art may derive other variations of the invention within the scope of the disclosed claims without departing from the subject matter of the claimed invention. In particular, all individual features described in connection with the various embodiments may be combined in other ways within the scope of the disclosed claims without departing from the subject matter of the claimed invention.
[0054] Thus, a metal sleeve, for example, which is injection-molded, can be inserted into the central bearing opening 13 of the cable roller 8. This allows the annular cable roller 8 to be designed with a particularly large inner diameter d of the central bearing opening 13. i Such a large bearing diameter makes it possible to minimize the material of the annular cable roller 8 , in particular by making the cable roller particularly thin-walled.
[0055] Furthermore, the described solution can be used not only for the specific application shown, but also for similar embodiments in other automotive applications, for example in door and tailgate systems, in window lifters, in vehicle locks, in adjustable seat systems and interior systems, as well as in electric drives, controllers, sensors and their installation in the vehicle.
