Description

Housing for a rope drum

description

The invention relates to a housing for receiving a cable drum of an adjusting device for a motor vehicle according to the preamble of patent claim 1.

Such a housing comprises a bearing point for rotatable mounting of the cable drum; a (possibly multi-part) wall which encompasses the cable drum along its outer surface when it is stored (at the bearing point) in the housing; as well as a securing element which is arranged in the region of the wall of the housing, in particular protrudes from the wall of the housing in the direction of the bearing point, and which serves to secure a traction means which wraps around the cable drum along its lateral surface provided with guide means.

Such a housing can be used, for example, to mount the cable drum of a cable window lifter, which has a flexible traction device for lifting and lowering a window pane in a motor vehicle, which wraps around a cable drum and can be moved by rotating the cable drum in such a way that the window pane to be adjusted - depending on Direction of rotation of the rope drum - is raised or lowered. The cable drum is for this purpose via a gear with a drive, for. B. in Form of a drive motor, coupled, which generates the drive torque required to rotate the cable drum.

The securing element provided on the housing serves to hold a traction means wrapping around the rope drum in the guide means (guide grooves) on the outer surface of the rope drum, i.e. to prevent the traction means from slipping out of individual guide grooves of the rope drum when they are on the bearing provided for this purpose Housing is stored. The securing element is used in particular to secure the traction device in the preassembled state of the housing and rope drum, i.e. before installing the assembly consisting of the housing and cable drum in a motor vehicle window lifter (transport lock).

There is a risk here that when installing the cable drum in the housing, i. H. when the cable drum is placed on the bearing of the housing provided for this purpose, the traction means can be pressed from one guide groove into another (adjacent) guide groove of the cable drum under the action of the securing element protruding radially inwards (compared with the other edge sections of the housing), so that the rope spools.

The invention is therefore based on the problem of further improving a housing of the type mentioned at the outset.

According to the invention, this problem is solved by the features of patent claim 1.

The securing element is then designed to be elastic and can be deformed in the radial direction, in relation to the bearing point of the housing.

Thus, the securing element during assembly, i.e. H. when the cable drum is installed in the housing, give way to the outside due to its elasticity in the radial direction, which prevents the securing element from acting on a traction means that wraps around the cable drum from a guide groove into another guide groove on the outer surface of the cable drum.

The securing element has a stop surface which faces the bearing point of the housing or the outer surface of a cable drum mounted on this bearing point and which, in the pre-assembled state of the housing and cable drum, that is to say in front their installation in a motor vehicle window lifter, in particular during transport, is intended to prevent the traction device from sliding off the outer surface of the cable drum by acting radially on the traction device.

So that the securing element can be moved sufficiently far in the radial direction outward away from the bearing point by elastic deformation, the securing element is connected to the wall of the housing only in a partial area via a connecting section and, moreover, on its side facing away from the bearing parts from the inner wall spaced from the housing. In other words, on the side of the securing element facing away from the bearing point, a free space is provided, into which the securing element can move radially outwards in the event of elastic deformation, so that the required flexibility is ensured when installing the cable drum and housing. The securing element can be integrally formed in one piece on the housing, in particular on the (single or multi-part) wall of the housing.

In addition to the elastic securing element, additional securing areas can be provided on the wall of the housing, in particular in the form of integrally molded securing surfaces protruding radially inward from the wall, in order to be able to reliably secure a traction means on a cable drum inserted into the housing, if the assembly of the corresponding window lifter has not yet been completed, in particular also during assembly.

The bearing point of the housing provided for mounting a cable drum can be formed by a bearing element in the form of a (physical) bearing axis, which is arranged on a bottom surface of the housing, preferably integrally formed thereon.

According to a preferred development, the bearing point has a form-locking element for the form-fitting holding of a cable drum mounted on the bearing point, which can be formed, for example, by a projection projecting radially outward from the bearing point. Due to the elasticity of the housing in the area of the elastic securing element, the corresponding positive locking element can be rigid, since the elasticity required in the production of the positive locking between a cable drum and the housing is provided by the securing element provided in the area of the housing wall. It is therefore not necessary to design the form-fitting connection between the housing and the cable drum itself to be elastic (for example in the manner of a clip connection). Of course If required, however, a housing designed according to the invention can also be connected to a cable drum rotatably mounted in the housing by means of an elastic latching connection (clip connection).

The possibility opened by the elasticity of the housing in the area of its housing wall (because of the elasticity of the securing element) to use a rigid positive connection for the rotatable mounting of a cable drum in the housing has the further advantage that, as an alternative to a positive connection, a rivet connection for the rotatable Storage of the cable drum in the housing (in particular in a housing arranged on a base plate made of metal with a metallic bearing point in the form of a bearing journal or pull-through) can be used without modifications to the cable drum being necessary. That is, one and the same rope drum can - depending on the design of the floor surface and the bearing point of a housing designed according to the invention - with the corresponding housing by positive locking (in the case of a bearing point provided with corresponding positive locking elements) or by riveting (in the case of a for producing a Rivet connection deformable bearing) can be connected. Thus, no different tools are required to produce different cable drums for snap connections on the one hand and rivet connections on the other.

Furthermore, the housing comprises guide areas, which serve as rope inputs or rope exits for a traction means to be fed to the interior of the housing, the guiding areas preferably guiding the traction means in such a way that it radially inwards, in the direction of the bearing point of the housing or in the direction of the Shell surface of a cable drum mounted in the housing is biased. This means that during operation of the window lifter, the radial forces acting on the traction device do not act on the securing element outwards, but act radially inward away from the securing element, so that the window lifter is relieved as much as possible.

For this purpose it can be provided that the guide areas define two guide channels, one of which serves as a rope entrance and the other as a rope exit and which - viewed from the bearing point - has an angle of less than 180 °, in particular an angle between 120 ° and 180 ° , particularly preferably include an angle between 145 ° and 180 ° (eg 150 ° or 175 °). In this case, the securing element is preferably arranged in the region of the wall of the housing in which the two guide channels merge into one another. According to another embodiment of the invention, the two guide channels - based on the bearing point - define an angle of more than 180 °, in particular an angle between 140 ° and 180 ° (e.g. 150 °). In this case, the elastically deformable securing element is preferably arranged on a wall area of the housing, which — with respect to the bearing point — is arranged radially opposite that wall area in which the two guide channels meet.

A combination of a housing designed according to the invention with a cable drum mounted therein on the bearing point is characterized by the features of patent claim 25.

In this case, a bearing element of the housing forming the bearing point preferably passes through an associated bearing opening (bearing bore) of the cable drum. The guide means provided on the outer circumferential surface of the cable drum for a traction means which wraps around the cable drum are preferably formed by guide grooves (cable grooves).

In order to reliably prevent when the cable drum is placed on the bearing of the housing provided for this purpose, that a traction means wrapping around the cable drum on its outer circumferential surface can slip off the circumferential surface, the securing element in the installation or insertion direction of the cable drum has such a length that the axial section of the cable drum wrapped by the traction means is covered by the securing element during the entire assembly movement of the cable drum with respect to the housing. The assembly path of the cable drum relative to the housing is understood to mean that part of the relative movement of the cable drum and housing when the cable drum is placed on the housing, in which the (preferably form-fitting) connection between the cable drum and housing is established and in which there is relative movement of the cable drum and housing in the radial direction (based on the bearing for the cable drum). (The relative movement between the cable drum and the housing is to be understood in such a way that to insert the cable drum into the housing, either the cable drum is inserted into the stationary housing or the housing is slipped over the stationary cable drum or the cable drum and housing are moved towards one another.) that when the cable drum is inserted into the housing for the rotatable mounting of the cable drum on the bearing location of the housing provided for this purpose, a section of the cable drum looping traction means in the axial direction (corresponding to the direction of insertion of the cable drum into the housing) is always completely covered by the elastic securing element in order to prevent the traction device from slipping off the outer surface of the cable drum.

Further features and advantages of the invention will become clear in the following description of exemplary embodiments with reference to the figures.

5b shows a modification of the cable drive housing from FIG. 5a in a plan view.

FIGS. 1a and 1b show a housing 1, 3, 4 which serves as a cable drive housing for the rotatable mounting of a cable drum 8 on a bearing 2 in a bottom surface 1 of the housing. The cable drum 8 forms part of an adjusting drive of a motor vehicle, for example a cable window lifter, and has a bearing opening 8 for rotatable mounting on the bearing point 2 of the cable drive housing, and furthermore an internal toothing 81, via which a torque into the with a suitable gear element provided with external toothing Cable drum 8 can be introduced in order to generate a rotary movement of the cable drum 8 along one or the other direction of rotation about the axis of rotation D defined by the bearing point 2.

On an outer circumferential surface (circumferential surface 85) of the cable drum 8 which is circular in cross-section, guide grooves 86 (cable grooves) are formed in the circumferential direction, which for guiding a drive wrapping around the cable drum are centered in the form of a flexible traction means, e.g. B. a rope. The bearing section forming the bearing opening 80 and the axially adjoining section of the cable drum 8 provided with internal teeth 81 are connected to the outer circumferential surface 85 having the guide grooves 86 by means of radially extending webs 83.

By coupling the traction means to the outer surface 85 of the cable drum 8 via the guide grooves 86 provided there, a rotary movement of the cable drum 8 generates a corresponding movement of a traction means that wraps around the cable drum 8. By the traction means on the other hand with a motor vehicle part to be adjusted, for. B. via a driver with an adjustable window of a motor vehicle door, is in operative connection, a rotary movement of the cable drum 8 is implemented via the traction means in an adjustment movement of the corresponding adjustment part, the direction of adjustment of which depends on the direction of rotation of the cable drum.

The cable drum 8 is accommodated in a cable drive housing 1, 3, 4 shown schematically in FIGS. 1a and 1b and is rotatably supported there on its bearing point 2.

The cable drive housing is formed on a base surface 1, from which protrude two integrally formed boundary walls 3, 4 of the cable drive housing, which enclose a partial region of the base surface 1 forming the base region 10 of the cable drive housing.

On this floor area 10 of the cable drive housing, the bearing point 2 is provided in one piece in the form of a physical bearing axis formed by a passage (molded on). Between a directly adjoining the floor area 1 Base section 20 and a partially circumferential, radially outwardly protruding projection 21 of the passage 2 has a constriction 22 which forms the actual bearing for the storage area in the form of a bearing opening 80 of the cable drum 8. The rope drum 8, which is rotatably mounted on the constriction 22 of the passage 2, is overlapped at the edge of its bearing opening 80 on the one hand by the base section 20 of the passage 2 and on the other hand by the axially spaced outwardly projecting projection 21, so that the rope drum 8 with the edge of it Bearing opening 80 is held in a form-fitting manner between the base region 20 and the projection 21 of the passage 2 on its constriction 22 — freely rotatable.

As can be seen from FIG. 1 a, the partially circumferential projection 21 of the passage 2 in the radial direction r (see FIG. 1 b) has different degrees of strength in order to facilitate the placement of the cable drum 8 with its bearing opening 80 on the passage 2 of the cable drive housing.

In the assembled state, the outer surface 85 of the cable drum 8 is surrounded by the two walls 3, 4 of the cable drive housing. The one wall 3 of the cable drive housing extends in a ring shape or circular in cross section at an angle of more than 180 ° in front of the outer surface 85 of the cable drum 8 provided with the guide grooves 86 and has an inner surface 30 opposite the outer surface 85 of the cable drum. At two end sections 31, 32, the first wall 30 of the cable drive housing is angled outwards to form a respective guide channel 6, 7 for a traction means that wraps around the cable drum 8, in particular in the form of a cable.

The guide channels 6, 7 are formed by said angled end sections 31, 32 of the first wall 3 together with two spaced end sections 41, 42 of a second wall 4 which is arranged opposite the first wall 3 and which is also one of the outer surface 85 of the cable drum 8 facing inner surface 40. However, the second inner wall 4 is not curved in a circle, but rather is formed by two wall sections 4a, 4b which run at a slightly acute angle to one another and which, based on the bearing parts 2, have an angle α of less than 180 °, for. B. include an angle α = 175 °.

In the area of the second wall 4, in which the two wall sections 4a, 4b meet, the second wall 4 - from the bearing point 2 of the

Seen cable drive housing forth - in a central section 45 slightly to the rear and there is in one piece with a connecting section 51 molded securing element 5 provided. This has a first surface 50, which serves as a stop or support surface and faces the outer surface 85 of the cable drum 8, and a second surface 52, which faces away from the outer surface 85 and therefore faces the recessed (middle) section 45 of the second wall 4. A free space F extends between this second surface 52 of the securing element 5 and the recessed wall section 45 of the second wall 4, ie the surface 52 of the securing element 5 facing the middle wall section 45 is spaced apart from that recessed wall section 45 in the radial direction r.

The securing element 5 lies with its surface 50 facing the lateral surface 85 of the cable drum 8 in relation to that area of the passage 20 in which its outwardly projecting, partially circumferential projection 21 has the greatest extent in the radial direction r to the outside. This means that at this point, when the cable drum 8 is placed on the passage 2 of the cable drive housing that serves as a bearing point, a comparatively large relative movement in the radial direction r to the outside is required in order to move the cable drum 8 under a certain inclination with its bearing opening 80 over the To push projection 21, wherein a slope 23 provided on the projection 21 has a supporting effect.

Such a relative movement in the radial direction r is made possible by the above-described, in the radial direction r, elastic design of the securing element 5, which is only integrally connected to the second wall 4 via a connecting section 51 in the form of a connecting web at one side end, but otherwise is spaced from it by a free space F, so that the securing element 5 can be moved into said free space F by deformation in the radial direction r.

This elasticity of the securing element 5 ensures that when the cable drum 8 and the cable drive housing are assembled, it does not act with such a force on a traction means running in the guide grooves 86 of the cable drum 8 that it would be pressed out of the associated guide groove. Rather, the elastic securing element 5 yields when radial forces act and can be deformed outward in the radial direction r in order to permit trouble-free assembly of the cable drum 8 and cable drive housing. This prevents the traction device from spooling during assembly, ie slipping of the traction device from a guide groove 86 into an adjacent guide groove. In addition to the elastic securing element 5 in the central area of the second wall 4, securing areas 305 protruding radially inwards are provided on the inner surface 30 of the first wall 3 in the form of securing areas, which serve to secure a traction means guided in the guide grooves 86 of the cable drum 8, that is to say in particular to prevent a traction means guided on the outer lateral surface 85 of the cable drum 8 from slipping out of the respective guide groove 86. This is to ensure that a traction device cannot slide off the cable drum 8 even if the traction device is still loosely in the guide grooves 86 of the cable drum during the assembly process (ie before the corresponding window lifter is finally assembled). The securing areas 305 in the form of securing areas are preferably arranged (distributed) along the circumference of the first wall 3 in such a way that none of the securing areas 305 is radially opposite the elastic securing element 5 with respect to the bearing point 2.

In the assembled state of the cable drum 8 and the cable drive housing, as shown in FIG. 1a, the securing element 5, which is then relaxed in the radial direction, is located in front of an assigned section of the outer surface 85 of the cable drum 8, so that it is removed from the cable drive housing during transport and storage the cable drum 8 existing assembly prevents slipping of a traction means wrapping around the outer surface 85 of the cable drum 8.

If later the assembly consisting of the cable drum 8 and the cable drive housing in an adjusting device of a motor vehicle, for. B. a window lifter is installed, then a sliding of the traction means from the lateral surface 85 of the cable drum 8 is no longer possible due to the then existing tension on the traction means. The securing function of the securing element 5 is no longer essential under these conditions.

Due to the slightly angled course of the two guide channels 6, 7, which serve as rope entrance and rope exit for a traction means wrapping around the rope drum 8 on its outer circumferential surface 85, a reaction force acts on a traction means running through these channels 6, 7 during operation of the respective adjusting device K in the radial direction inwards. This prevents the traction device from loading or sliding against the securing element 5 during operation of the corresponding adjusting device. FIGS. 2a and 2b show a further development of the cable drive housing described with reference to FIGS. 1a and 1b, the further developed drive housing being additionally shown in FIGS. 3 and 4 together with a cable drum 8 mounted therein. In principle, the design of the cable drive housing and the cable drum 8 correspond to the exemplary embodiment described with reference to FIGS. 1a and 1b, identical reference numerals being used to indicate the agreement for matching assemblies. The differences between the arrangement shown in FIGS. 2a and 2b, 3 and 4 on the one hand and the exemplary embodiment shown in FIGS. 1a and 1b on the other hand are therefore only briefly explained below. For the rest, reference is made to the above statements relating to FIGS. 1a and 1b.

On the one hand, the cable drive housing shown in FIGS. 2a, 2b, 3 and 4 differs from that shown in FIGS. 1a and 1b in the size of the base plate defining the base surface 1, from which the lateral boundary walls 3, 4 of the housing protrude. The extent of this floor area 1 is in the present case considerably larger than the floor area 10 of the actual housing enclosed by the boundary walls 3, 4 and is provided with fastening points B for fastening the housing to other vehicle components, eg. B. on a gear unit, in particular a gear housing. In addition, the lateral boundary walls 3, 4 of the housing are provided with stiffening ribs 35 which extend from the boundary walls 3, 4 to the bottom surface 1 of the housing base plate.

Another difference is that the guide channels 6, 7 serving as rope inlets and rope exits, each formed by end sections 31, 41; 32, 42 of the lateral boundary walls 3, 4 of the cable drive housing have a significantly greater length than in the case of FIGS. 1 a and 1 b and that guide bushes 60, 70 are provided at the ends of these guide channels 6, 7, which provide a defined supply of a traction means S to ensure the respective channel 6, 7.

Moreover, it can be seen particularly clearly from FIGS. 2a and 2b that the projection 21, which partially surrounds the passage 2, has a different shape in the radial direction r and that this projection 21 in a region (viewed in the circumferential direction) in which it extends in the radial direction r rests against the elastic securing element 50, which has the greatest extent in the radial direction r. It can be seen from FIG. 3 that the securing element 5 in the axial direction a, which at the same time corresponds to the direction along which the cable drum 8 and the cable drive housing are joined during assembly, has a significantly greater extent (length L) than that with guide grooves 86 Provided area of the outer surface 85 of the cable drum 8 with an axial extent T <L. This ensures that when the cable drum 8 and cable drive housing are assembled, the area of the outer surface 85 of the cable drum 8 opposite the securing element 5 and provided with guide grooves 86 already exists in the axial direction a is completely covered by the securing element 5 when the edge of the bearing opening 80 of the cable drum 8 slides over the bevel 23 on the projection 21 of the passage 2 which serves to mount the cable drum 8 and thereby executes a movement in the radial direction r. This ensures that when the cable drum 8 and the cable drive housing are assembled, the traction means S running in the form of a rope along the guide grooves 86 is already covered by the securing element 5 along the entire extent T of the guide grooves 86 in the axial direction a in order to prevent them from slipping out To divide the traction device S from one of the guide grooves 86 and thus prevent the traction device S from spooling.

The configuration of a cable drive housing for mounting a cable drum of an adjusting device in a motor vehicle described above with reference to FIGS.

Figure 5a again shows a cable outlet housing of the type shown in Figures 1a and 1b in a schematic plan view. With regard to the description of the cable outlet housing shown in FIG. 5a, reference is made to the explanations relating to FIGS. 1a and 1b, the same reference numerals being used in FIG. 5a for corresponding components of the cable outlet housing as in FIGS. 1a and 1b.

FIG. 5b shows a schematic representation of a modification of the cable outlet housing from FIG. 5a, and thus also a modification of the housing from FIGS. 1a and 1b, an essential difference being that the two guide channels 6 ', 7' - each formed by angled ones End sections 31, 32 of the first wall 3 together with two assigned end sections 41, 42 of the second wall 4 - with respect to the bearing point 2, an angle β of more than 180 °, for example 210 °, lock in. The two guide channels 6 ', 7' accordingly form a crossed rope exit.

Here, according to a second difference to the embodiment of a cable outlet housing shown in FIGS. 1 a, 1 b and 5 a, the elastic securing element 5 is not arranged in a central region of the second wall 4, in which the two forming the second wall 4 are at an angle to one another running wall sections 4a, 4b meet, but rather the central area of the second wall section 4 radially - in relation to the bearing point 2 - opposite in a central area 300 of the first wall 3. The securing element 5 is in turn integrally formed there by means of a connecting section 51 and has on the one hand one of the bearing point 2 (and thus the lateral surface of a cable drum inserted into the corresponding housing) facing surface 50, which acts as a stop or. Serves as a support surface and, on the other hand, a second surface 52 facing the recessed central section 300 of the second wall 3. A free space F extends between this second surface 52 of the securing element 5 and the recessed wall section 300 of the first wall 3 or an elevation 300a provided there. ie the surface 52 of the securing element 5 facing the middle wall section 300 or the elevation 300a there is radially spaced from that recessed wall section 300 and the elevation 300a there. This corresponds to the distance in the radial direction r between the surface 52 of the securing element 5 facing the central wall section 45 or an elevation 45a there from that recessed wall section 45 or its elevation 45a in the embodiment of a shown in FIGS. 1a, 1b and 5a Rope outlet housing and leads to a corresponding technical function, cf. the relevant comments on Figures 1a and 1b.

The partially circumferential projection 21 of the bearing point 2 formed by a passage 20 lies with its area of greatest expansion in the radial direction r in each case opposite the elastic securing element 5, so that the area of greatest expansion of the projection 21 in the exemplary embodiment shown in FIG. 5b is 180 ° is arranged rotated relative to the embodiment shown in Figure 5a.

As a result, both in the exemplary embodiment shown in FIG. 5a and in the exemplary embodiment of a cable outlet housing shown in FIG. 5b, the additional radially inwardly projecting securing areas 305 are in the form of Securing surfaces are each arranged at an angle to the reaction forces generated by the respective securing element 5 or by a tensioned traction means in the area of the securing element 5 (cf. reaction forces K in FIG. 1 b).
