Description

Adjustment device with a deflection assembly

description

The invention relates to an adjusting device for adjusting an adjusting part of a vehicle according to the preamble of claim 1.

Such adjusting device has a support plate, a drive unit and a traction means for transmitting an adjusting force from the drive unit to an adjusting part to be adjusted. For deflecting the traction means at at least one deflection point, at least one deflecting subassembly is provided which has a carrier element for connecting the deflecting subassembly to the carrier plate and a deflecting element arranged on the carrier element for deflecting the traction means. The deflecting element can be designed, for example, as a deflecting roller, is arranged rotatably about the carrier element about a deflection axis on the carrier plate and deflects the traction means in such a way that it extends in the area of the deflecting element substantially in a traction center plane. In an adjusting device of this type known from DE 10 2008 024 742 A1, a carrier element, which rotatably connects a deflecting element to an assembly carrier, is supported with a supporting section relative to the unit carrier in such a way that Loading forces can be introduced into the subframe. For this purpose, the subframe has a projecting support section with reinforcing ribs which provide targeted support of the carrier element in the direction of the loading forces introduced via the traction means onto the deflecting subassembly.

In a module carrier known from WO 2004/087450 A1, receptacles in the form of shoulders and / or pockets are provided, on which deflecting elements belonging to a deflection device in the form of rollers or deflection blocks for deflecting a traction means are fastened.

Object of the present invention is to provide an adjustment device with a deflection assembly available, which allows easy installation with fixed connection of the deflection assembly to the support plate in the assembled state and at the same time can provide a reliable support against acting in operation of the adjustment device loading forces.

This object is achieved by an article having the features of claim 1.

It is provided that the support element of the deflection assembly is held in a perpendicular or oblique to the Zugmittelebene facing insertion to a bearing portion of the support plate attachable and in the assembled state via a latching connection form-fitting against the insertion of the bearing portion of the support plate.

The support plate of the adjustment device can be designed, for example, as a subframe of a vehicle door, which carries an adjustment device in the form of a (cable) window lifter. The adjusting forces are transmitted via a traction means in the form of a rope that is deflected at one or more deflection points by one or more Umlenkbaugruppen.

It is also conceivable that the support plate is formed for example by the door inner panel of a vehicle door.

The deflecting element can be designed, for example, as a deflecting roller and can be arranged rotatably about the deflecting axis on the carrier element via a bearing journal be. The support member thus provides a storage for the deflection available and connects this with the support plate, wherein on the support member loading forces can be introduced in a suitable manner in the support plate. On the bearing journal can be formed a passage opening for the passage of a fastening means for fastening the deflection assembly to the support plate and / or a body portion of a vehicle. For example, it can be provided to connect the carrier element via the bearing journal by means of a screw directly to a body section (for example, the door inner panel of a vehicle door), so that the support plate (for example, an assembly carrier) is clamped between the support member and the body portion and thus on the screw also connected to the body section. The carrier element thus serves on the one hand for the arrangement of the deflection assembly on the support plate, but on the other hand simultaneously provides an attachment point for the attachment of the support plate to a body portion of a vehicle.

The carrier element of the deflecting assembly is positively connected via a latching connection with the carrier plate, wherein the latching connection sets the carrier element in particular against the insertion direction, so that the deflecting assembly can not (without further) counter to the insertion from engagement with the bearing section. For this purpose, at least one positive locking element, for example in the form of a snap hook, may be formed on the carrier plate, against which, in the assembled state of the deflecting module, at least one support section of the carrier element bears in a form-fitting manner and thus produces the latching connection. It is conceivable that in a specific embodiment of the support plate at least two positive locking elements are arranged, of which at least one is formed elastically. For example, a first positive locking element may be rigid and a second positive locking element may be resilient at least in one direction. The resilient design of the second positive locking element makes it possible to attach the carrier element together with the deflecting element arranged detent on the carrier plate by a first support portion of the support element attached to the (rigid) first positive locking element and a second support portion latching with the (elastic) second positive locking element is engaged.

Conceivable in this context is also to form both form-locking elements of the support plate rigid and one or more of the support sections of the Carrier element of the Umlenkbaugruppe at least partially elastic form, so that the positive locking connection can be made by the elastic formation of at least one support portion. Advantageously, the carrier element extends at least in sections flat and is arranged in an at least partially cylindrical, the bearing portion forming bearing cup on the support plate. In the bearing cup, the deflection assembly can be used in the transversely or obliquely to the traction means standing plug-in direction, optionally also pivoted. The bearing cup receives the carrier element and supports it, for example by the carrier element rests against the cylindrical wall of the bearing cup via at least one axially directed in the direction of the deflection axis support portion. In this way, a support in the direction of the loading forces acting during operation of the adjusting device can be provided in this way in particular via the support section, so that the deflection assembly is securely held on the carrier plate even with loading forces acting on the deflection assembly via the traction means and provide a deflection of the traction means can.

In an advantageous embodiment, the deflecting assembly can be supported via at least one support portion relative to the bearing cup, that upon loading the Umlenkbaugruppe by acting on the traction load forces the Umlenkbaugruppe is acted upon by a moment that pushes the Umlenkbaugruppe into the bearing cup. For this purpose, the deflection assembly can be supported over the at least one support section in a planar or punctiform manner relative to the carrier plate, such that the acting loading forces cause a moment on the deflection assembly about the planar or punctiform support into the bearing cup. This is the case, in particular, when a support point on which the deflecting assembly is supported relative to the carrier plate is arranged above a plane in which the traction means extends around the deflecting element so that the loading forces acting on the traction means bring a torque into the bearing cup produce.

About the support member, the deflection assembly is arranged and supported on the support plate of the adjusting device. To the support member in this case also in the circumferential direction rotatably on the support plate to arrange and in particular to secure against rotation about the deflection around, axial ribs may be arranged on the bearing cup, which extend substantially parallel to the deflection axis and a backup against rotation in the circumferential direction in particular make available that they rest on at least one support portion of the support element. Thus, a support portion of the carrier element, for example, at its lateral, axial edge portions each having an axial rib in abutment, so that held between the axial ribs of the support portion and secured against rotation in the circumferential direction.

For a firm connection of the carrier element with the carrier plate, the carrier element can further engage with a receiving portion in a passage opening of the carrier plate and thus enter into a kind of spigot joint for supporting the carrier element relative to the carrier plate. In order to simplify the assembly of the deflecting assembly on the support plate, the passage opening of the support plate may be at least partially conically shaped in its wall, so that the support member pivoted into the storage pot of the support plate for producing the latching connection and inserted with its receiving portion in the passage opening of the support plate can be. For example, it may be provided for mounting, the carrier element with a support portion initially attach to a form-fitting element of the support plate in order then zoom in the support member around this support portion in the storage cup of the support plate. In order for the receiving section of the carrier element to be inserted into the passage opening of the carrier plate during this inward pivoting, the passage opening is conical at least in an edge section, so that the receiving section can pivot into the passage opening.

In particular, in the embodiment of the adjusting device as a window regulator for adjusting a window pane of a vehicle door, the adjusting device may have one or more guide rails, which may be formed on the carrier plate in an advantageous embodiment. The deflecting assembly may then be arranged at one end of a guide rail, wherein at a cable window lifter at each end of each guide rail a deflection assembly is provided regularly. Thus, a double-stranded cable window lifter with two parallel guide rails, for example, four deflection assemblies, which are arranged in the region of the ends of the guide rails.

Advantageously, the support plate of the adjusting device is produced as a plastic molded part and can also carry other functional components as an integrated subframe of a vehicle door module. The carrier plate can be produced for example by injection molding, wherein the carrier plate advantageously so is configured that eliminates the use of a slider in an injection mold. For this purpose, recesses may be provided in the carrier plate on the support plate, for example for the formation of form-locking elements for producing the latching connection, which allow a penetration of pins of an injection mold in the production of the carrier plate and thus make a slide in the injection mold superfluous. The support plate can be made in this case by simple injection molding in one operation, without the need to subsequently be molded using a slider certain sections.

The idea underlying the invention will be explained in more detail with reference to the figures illustrated embodiments. Show it:

7a, 7b, 7c are sectional views through the deflection assembly and a bearing cup of the carrier plate when attaching the deflection assembly to the support plate and 8 shows a sectional view through a section of the carrier plate with schematically sketched injection molding tools for forming the carrier plate. Fig. 1 shows a side view of an adjusting device 1 in the form of a double-stranded cable window lifter, in which on a support plate 10 laterally two guide rails 1 1, 12 for slidably guiding two drivers 13, 14 are arranged. About the drivers 13, 14, an adjustment in the form of a window pane (not shown) are connected to the adjustment device 1 to move the adjustment along the guide rails 1 1, 12 for opening or closing a window opening of a vehicle door.

On the support plate 10, a drive unit 16 of the adjustment device 1 is arranged, which drives a traction means 15 in the form of a trained example of steel rope. About the traction means 15, the drive unit 16 is connected to the drivers 13, 14 and directs adjusting forces for adjusting the adjustment in the driver 13, 14 a. The traction means 15 forms for this purpose a closed cable loop by the traction means 15 of the drive unit 16 toward an upper deflection point 1 10 of the guide rail 1 1, from there along the guide rail 1 1 to a lower deflection point 1 1 1, from the lower Deflection point 1 1 1 diagonal to an upper deflection point 120 of the guide rail 12, then along the guide rail 12 toward a lower deflection point 121 and from there back to the drive unit 16 extends. The drive unit 16 may comprise a cable drum in a conventional manner, to which the traction means 15 is unwound at one end on and with another end during a rotational movement, so that a displacement movement of the traction means 15 results, as a result of which the drivers 13, 14th rectified up or down along the guide rails 1 1, 12 are moved.

At each of the deflection points 1 10, 1 1 1, 120, 121, a deflection assembly 2 is arranged, as shown in Fig. 2 to 4 in detail. The deflecting assembly 2 has a deflecting element 21 in the form of a deflection roller, which guides the traction means 15 for deflection at a groove 210 and for this purpose rotatably about a pivot pin U to a support member 22 and via the support member 22 to the support plate 10 of Adjustment device 1 is connected. The bearing pin 23 passes through a through-opening 21 1 of the deflecting element 21 and is inserted into a cylindrical receiving portion 222 of the support element 22 (see FIG. 4). In the assembled state of the deflecting assembly 2, the deflecting element 21 is located between support sections 220, 221 of the carrier element 22 and is held rotatably on the carrier element 22 via the bearing pin 23. The support sections 220, 221 can also provide a cable safety device which prevents the traction means 15 from coming out of the groove 210 of the deflecting element 21 in operation of the adjusting device 1.

The deflection assembly 2 is connected via the carrier element 22 with the support plate 10 of the adjustment device 1 (see FIG. 3). The connection takes place while producing a latching connection in a form-fitting manner, wherein the deflection assembly 2 is attached in an insertion direction B to the support plate 10 and the support portions 220, 221 of the support member 22 with positive locking elements 24, 25 of the support plate 10 is engaged to produce the locking connection be used by the deflection assembly 2 as a whole in an at least partially cylindrical bearing cup 26 of the support plate 10.

The plug-in direction B, in which the deflection assembly 2 is attached to the support plate 10, namely the bearing cup forming a bearing portion 26, is au ßerhalb a Zugmittelebene E (see Fig. 7c), in which the traction means 15 extends around the deflector 21. For example, the plug-in direction E may extend vertically (as in the example shown) or obliquely to the tension center plane E. The attachment can basically be done in a straight line manner or by pivoting into the bearing cup 26, as will be explained below.

As shown in Fig. 3, axially to the deflection axis U extending axial ribs 241, 242, 251, 252 are arranged on the inside of the bearing cup 26 on cylindrical wall portions of the bearing block 220, 221 of the support member 22 laterally in mounted deflecting assembly 2 Are system, so that the support member 22 is secured against rotation about the deflection axis U during operation of the adjustment device 1. In the assembled state, the deflection assembly 2 is thus held in a form-fitting manner in the bearing cup 26 via the support sections 220, 221 of the carrier element 22 and also rotationally fixed via the axial contact of the axial ribs 241, 242, 251, 252 with the support section 220, 221.

A plan view of the support plate 10 in the region of the deflection point 121 according to FIG. 1 is shown in FIG. 5. The axial ribs arranged inside the bearing cup 26 are clearly visible 241, 242, 251, 252, which are each adjacent to the associated positive-locking elements 24, 25 integrally formed.

In Fig. 6 and Fig. 7a to 7c, the mounting method for mounting the deflection assembly 2 on the support plate 10 is shown. The diverter assembly 2 as a whole - i. with deflecting element 21 attached to one another, carrier element 22 and bearing journal 23 - inserted into the bearing cup 26 of the carrier plate 10. For this purpose, the deflection assembly 2 is first attached to the support section 220 of the support member 22 to the positive-locking element 24 on the support plate 10, so that the support portion 220, the positive-locking element 24 engages behind (Fig. 7a). Subsequently, the deflecting assembly 2 as a whole about a pivot axis S (Fig. 6) - according to the upper edge of the support portion 220, which is located in the region of the positive-locking element 24 - pivoted into the arrowhead direction shown in Fig. 6 in the bearing cup 26, until also the support section 221 of the support element 22 opposite the support section 220 engages with the associated positive engagement element 25 on the support plate 10 (FIGS. 7b, 7c). For this purpose, the positive-locking element 25 is designed to be resilient such that the support section 221 can press the positive-locking element 25 radially outwards and thus engage with the positive-locking element 25. In the assembled state (FIG. 7c), both the support section 220 and the opposite support section 221 of the carrier element 22 then engage with the respectively assigned positive-locking elements 24, 25 and are held in a positive-locking manner against the insertion direction B.

As already mentioned, the bearing pin 23 of the deflection assembly 2 engages in the receiving portion 222 of the carrier element 22. The receiving portion 222 stands, as shown in Fig. 7a to 7c, on the underside of the support member 22 and engages in the assembled state of the deflection assembly 2 (Fig. 7c) in a through-opening 27 on the bearing cup 26 a. As can be seen from FIGS. 7a to 7c and also shown in FIG. 5, the passage opening 27 has different edge sections 270, 271, which are cylindrical in shape (edge section 270) and conical (edge section 271). The conical design of the edge portion 271 is such that the diameter of the passage opening 27 is widened at the bottom of the bearing cup 26 and the passage opening 27 tapers away from the bottom of the bearing cup 26. This conical design of the edge portion 271 is provided to the insertion of the receiving portion 222 into the passage opening 27th when pivoting the deflection assembly 2 in the bearing cup 26 (Fig. 7a to 7c) to allow easy.

Instead of the formation of the passage opening 27 with different edge portions 270, 271 is also conceivable, the passage opening 27 completely cylindrical (with a total expanded diameter) or continuous conical form. The embodiment shown in FIGS. 7a to 7c, however, has the advantage that an (additional) supporting abutment of the carrier element 22 on the carrier plate 10 is created over the cylindrical edge section 270.

As can be seen in particular from FIG. 7c (which shows the mounted state of the deflection assembly 2 on the carrier plate 10), the deflection assembly 2 is supported on the carrier plate 10 in particular in the installed state via the support section 220. This supporting section 220 is of outstanding importance because, during operation, the adjusting device 1 is moved by means of the traction means 15, essentially in a traction center plane E (guided on the groove 210 of the deflecting element 21 and in guide channels 122 (FIG. 6) of the carrier plate 10). runs, load forces F act on the deflection assembly 2, which press the deflection assembly 2 via the support portion 220 against the associated wall portion of the bearing cup 26. The associated wall portion of the bearing cup 26 in the region of the positive-locking element 24 is therefore advantageously reinforced to initiate the loading forces F in a suitable manner in the support plate 10 and to receive there. Reinforcing ribs can also be provided here, for example, which absorb the loading forces F in a reliable manner.

As shown in FIG. 7c, the supporting abutment of the support section 220 on the bearing cup 26 can be designed such that a substantially punctiform (or linear) support results over a support point D (or a flat support whose center of gravity lies in the interpolation point D). , If this interpolation point D, as shown in FIG. 7c, is arranged above the plane E, viewed from the interior of the bearing cup 26, in which the traction means 15 extends, the loading forces F cause a moment M on the deflecting subassembly 2 about the interpolation point D. around, which is directed into the bearing cup 26 and causes the deflection assembly 2 is pressed into the bearing cup 26 under load. When loaded so that the stop of the deflection assembly 2 in the bearing cup 26 is reinforced, so that the deflection assembly 2 can not get out of the bearing cup 26. As can be seen, for example, from FIGS. 4 and 7c, through openings 230, 223, 27 are formed both on the bearing journal 23 and on the carrier element 22 and in the bottom of the bearing cup 26, which can receive a fastening means in the form of a screw in order to engage over the Deflection assembly 2, the support plate 10 with an associated body portion of a vehicle, for example, to connect the door inner panel of a vehicle door. For this purpose, a screw is inserted into the through-opening 230 of the bearing pin 23 and engages in an associated mounting opening on the body portion, so that via the bearing pin 23, the deflection assembly 2 firmly connected to the body portion and the support plate 10 is clamped between the deflection assembly 2 and the body portion , In addition, the deflection assembly 2 also provides an attachment point for fastening the support plate 10 to a body section in this way.

The support plate 10 is advantageously produced as a plastic molding by injection molding. The support plate 10 is designed so that injection molds W1, W2, as shown in Fig. 8, can be used, which can dispense with a slide for the production of moldings or sections. For this purpose, the support plate 10 with recesses 240, 250 below the form-fitting elements 24, 25 designed so that all sections and areas of the support plate 10 by suitable pins 31, 32, 33 can be formed. In particular, the recesses 240, 250 and the passage opening 27 are at least partially conical, so that by means of at least partially conical pins 31, 32, 33, the recesses 240, 250 and the access opening 27 by joining the tools W1, W2 in the joining direction F1, F2 can be shaped. The support plate 10 can thus be produced in a single operation, without the need to be formed by using slides or the like additional areas or sections.

The idea underlying the invention is not limited to the above-described embodiments, but can in principle be realized even in completely different types of embodiments. In particular, the invention is not limited to use with adjusting device in the form of window regulators, but can also be used in other Versteilvorrichtungen that use a traction device.
