From the DE 200 03 277 U1 is a generic type coupling device is known, which consists of a lock with two parallel between an open and closed position against each other slidable bars, which when moving these bars in their closed position, these cooperate with a counterpart form and / or non-positively for the purpose of locking. In order to move this bolt between its open and closed position, a rotatable lock plate is provided, which establishes an operative connection with the bolts via crank mechanisms. By turning the lock plate, the two bars are moved between the open and closed positions.

Furthermore, the describes DE 10 57 496 B a device for closing motor vehicle doors, which comprises a on a door leaf or on a fixed door frame an electrically drivable engagement member and on the other part a corresponding receiving member for the drivable engaging member. In this case, a truncated cone-shaped latch can be used as the engagement member, which engages in a hollow truncated cone as a receiving member. Further It is also proposed that such a bolt and the associated receiving opening wedge-shaped, for example. Form in the form of wedge surfaces.

Finally, also from the DE 103 15 565 A1 a coupling device is known, which is used as a so-called power joint for releasably connecting a vehicle door with a door pillar, said vehicle door is hinged stop side with a power joint on the local door pillar. Further, this vehicle door has a Türausteifung connecting the power joint with the power lock, so that forces from the door pillars on the power steering and the power lock can be introduced into the vehicle door and thereby the rigidity of the vehicle body is increased.

That in this DE 103 15 565 A1 described power lock for detachable connection of a vehicle door with a B-pillar of a vehicle body has a door side arranged first coupling element and cooperating with this, body side fixed second coupling element, wherein in a closed state of the power lock, the two coupling elements without play abut each other so that Zug- and compressive forces can be transmitted to thereby increase the flexural rigidity of the connection between the vehicle door and the B pillar and the torsional rigidity of the vehicle body. Furthermore, to avoid high surface pressure and to compensate for any tolerances that may arise from the production or operation, wedge surfaces having holding body of the second coupling element provided, which engage correspondingly formed wedge surfaces of an engagement body of the first coupling element. In order to form the wedge surfaces, the holding bodies or the engagement bodies arranged on the door side are designed in the shape of a cone segment or truncated cone, wherein, for example, four such holding bodies are arranged radially around a Bolzano. The tension of the wedge surfaces, so the locking of the two coupling elements is effected by a motor drive or by an electromagnet, wherein in the case of a shutdown of the power supply of the drive, the two coupling elements unlocked become. The realization of this known adhesion requires a high number of kinematic components, which have a complicated geometry. In addition to this power lock, the vehicle door of the vehicle body additionally has a common door lock.
The object of the invention is to provide an improved over the prior art coupling device of the type mentioned, which can be produced in particular with a few and structurally simple components.
This object is achieved by a coupling device having the features of patent claim 1.
Such a coupling device for releasably connecting a pivotally mounted body part, in particular vehicle door, rear or front flap with a vehicle structural part of a vehicle body, with a first coupling element and a play coupled thereto in the coupled state of the coupling device second coupling element, wherein the first coupling element two parallel against each other has stored latch and a motor drive device is provided which moves by means of active connection means the bolt for coupling the two coupling elements apart, according to the invention is characterized in that the bars are formed as mounted in a cuboid keeper holder plate-shaped locking wedges with wedge surfaces, which for forming the Wedge surfaces have a side edge with wedge-shaped cross-section, and the second coupling element with two, the first coupling element between n receiving jaws formed with keyways, so that the locking wedges are pushed apart by the motor apart with their wedge surfaces in the keyways and are engageable with wedge surfaces of the keyways can be brought.

This coupling device according to the invention has only a few elements, in particular only two closing wedges are required, with which an effective positive connection between the two coupling elements is achieved, namely in all directions lying in the plane perpendicular to the wedge surfaces, i. relative to a coordinate system of a vehicle in both the x and z directions. In the direction in which the locking wedges are driven out of the keyways, there is a high adhesion.

Due to the use of simple locking wedges with incorporated in holding jaws keyways for receiving the locking wedges results in a simple structural design, which can be realized inexpensively both in terms of manufacturing and assembly.

By the plate-shaped locking wedges with wedge-shaped cross-sectional side edges of the structural design is further reduced because of complicated rotationally symmetrical body according to the prior art, such as truncated cone segments or truncated cones is dispensed with. The kinematics required for the separation of the two locking wedges in the keyways of the holding jaws apart can be realized with simple means.

In order to allow a positive connection in the y-direction in the direction of the vehicle interior, the splines extend conically in their longitudinal extension and the wedge surfaces of the locking wedges are adapted to this conical shape such that the insertion of the closing wedges when closing, for example, a vehicle door in the second Clutch element is facilitated, however, due to the tapering in the direction of the vehicle interior longitudinal grooves of the holding jaws and the matched thereto keying wedges in this direction, the two coupling elements and therefore also form a power transmission enabling positive engagement.

Alternatively or additionally, at least one of the closing wedges may be formed on the side opposite the holding jaws side edge with a locking nose, which moves into corresponding locking openings in the keyways of the holding jaws of the second coupling element during locking. As a result, a complete positive connection between the two coupling elements is also effected in the y direction, that is to say both in the direction of the vehicle interior and also to the outside.

Characterized in that, according to a further embodiment, the first coupling element has at least one return spring element connecting the strikers, which biases the two strikers toward each other, the two strikers must not be actively pulled out of the tension with the keyways when the cam disc in the corresponding position by means the motor drive device is rotated.

In an advantageous development of the invention, the operative connection means for producing the operative connection of the motor drive device with the closing wedges of the first coupling element comprise a cam disc with two diametrically opposed cam lobes, which is mounted in the first coupling element such that they are pressed by a rotation in an operative connection of the cam lugs with the locking wedges in the keyways.

Thus, the locking wedges slidably mounted in the first coupling element can be easily moved apart with the cam disc arranged therebetween, preferably in the plane of the locking wedges, into the keyways, symmetrical retraction of the closing wedges into the keyways of the holding jaws being effected by the opposing cam lobes.

According to a further embodiment of the invention, the operative connection means comprise a control disk, which is non-rotatably connected to the cam disk, wherein the rotational movement of the control disk is limited by means of a stop means such that the control disk between a first, the first and second coupling element decoupling position and a second the first and second coupling element coupling position is rotatable.

With such a control disk advantageous control of the motor drive device can be realized, since the limited rotational movement of the control disk leads to a detectable change of drive parameters, such as the motor current of an electric motor as a drive device and can be used to shut down the drive device.

Further, the active connection means further development according to a drive pulley, which is rotatably connected by means of a driver with the control disk, wherein the driver on the control disk is pivotally and spring loaded arranged such that the driver produces a releasable and rotationally fixed latching connection with the drive pulley and by one of the drive device caused rotational movement of the drive pulley the control disk is pivotable between the first and second positions.

With this driver, a releasable coupling between the drive side and the output side is realized, which is used manually to implement a manual emergency release.

According to an embodiment of the invention, this is realized by means of an emergency lever, which is displaceable in operative connection with the driver, such that the latching connection is released in the second position of the control disc with the drive pulley and a control disc in the direction of the first position biased spring element is provided, through which the control disk is pivoted in entrastetem driver in the first position.

In a power failure, this emergency lever is actuated via a door handle, as soon as the locking connection between the control disk and the drive pulley is released, the return spring elements pull the two locking wedges from the deadlock in the retaining jaws, so that, for example, a vehicle door can be opened.

An alternative embodiment of an emergency release is further education created by providing an axially to the control disc unlocking ring is provided with a control cam which can be brought to release the locking connection of the driver with the drive disc in operative connection with the driver and an actuating means is provided, with which a rotational movement the unlocking ring is caused from a rest position in at least one operating position, such that with the rotational movement first the locking connection is released at least in the second position, the control disk with the drive pulley and then the control disk is rotated via the driver in the direction of the first position.

This embodiment has the advantage that even with a failure of the motor drive device during the process of coupling the two coupling elements an emergency release is possible.

Preferably, in this embodiment, the rotational movement of the unlocking ring is effected by means of a pivotally mounted toothed segment element, in particular a toothed segment wheel or a rack, which is in engagement with a toothed segment of the unlocking, the Zahnsegmenrelement in one of the rest position of Entriege-. lungsrings corresponding spring-biased first pivot position, and by means of the actuating means, the toothed segment element is pivoted from the first pivot position into a unlocking ring in its operating position twisting second pivot position.

As actuating means in particular a Bowden cable device is provided, which is hinged at one end to the toothed segment element and the other end is connected to a door handle of the castle.

A particularly advantageous embodiment of the invention is given by the fact that a drive disc is rotatably coupled with the drive disc is provided, wherein the rotary coupling is formed by at least one hand with the drive plate and on the other hand connected to the drive disc clearance compensation spring element, and the rotary coupling a relative rotational movement between the drive pulley and the drive plate over a predetermined angle of rotation allows such that biased by a rotational movement of the drive plate in the direction of rotation D1 of the second position of the control disc, the drive pulley at least when reaching its end position in the same direction of rotation D1 and a play compensating further rotational movement with a maximum of the predetermined angle of rotation corresponding rotation angle is made possible ,

This rotational coupling between the drive pulley and the drive plate thus causes that in a rotation of the drive plate caused by the drive device in the direction of rotation of the second position of the control disk, the drive pulley is initially biased until it sufficient in the same direction of rotation in a position in which the locking wedges are braced without play in the keyways to take, with in this position the clearance compensating spring element is suppressed to a relative rotational movement limiting stop and thereby the spring force has risen to this position. If a play between the striker and the holding jaws occur when the drive device is switched off, caused by the Spielausgleichsfederelement spring force causes a relative rotational movement of the drive disc relative to the drive plate, which rotates the control disc with the cancellation of the resulting game further towards its second position, thereby thereby also the cam disc with its two cam lugs, canceling the resulting game pushes the two locking wedges further into the keyways.

This dynamic scoring between the two coupling elements is achieved when the drive device is switched off and thus constantly ensured during vehicle operation of the positive connection between the two coupling elements.

According to development connection means are provided which allow a relative rotational movement of the drive plate relative to the drive pulley with the predetermined angle of rotation and therefore form a relative rotational movement limiting stop. Preferably, as connecting means connected to the drive disc connecting pin and arranged on the drive plate longitudinal groove for receiving the connecting pin provided such that the longitudinal groove allows relative movement of the connecting pin according to the angle of rotation.

According to an advantageous embodiment, the drive plate comprises a worm wheel, which is driven by a worm of the motor drive device. Furthermore, the drive plate comprises a spring connection wheel which, together with the drive disc, receives the at least one clearance compensation spring element and has the longitudinal groove.

The motor drive device is self-locking, in particular designed as an electric motor for motor drive of the drive pulley or the drive plate.

The FIGS. 1 to 4 show a coupling device 100 with a first and second coupling element 10 and 20 as an embodiment in both separate representations of the two coupling elements 10 and 20 and in the connected state.

FIG. 1 shows the first coupling element 10 with a parallelepiped key holder 13, on whose longitudinal sides in each case a closing wedge 11 and 12 is slidably mounted in the z direction. The locking wedges 11 and 12 are each formed at their free end faces 11a and 12a to form two wedge surfaces 11b and 12b with a symmetrical wedge-shaped cross-section.

According to FIG. 1 the closing wedge holder 13 of the first coupling element 10 is arranged on a lining 17, which forms the end face of a vehicle door 3 of a vehicle body 1. Beyond this fairing 17, ie within the vehicle door 3, a motor drive device 30 and an operative connection between the closing wedges 11 and 12 and this drive device producing operative connection means 40 are arranged.

The second coupling element 20 after FIG. 2 comprises two on a base plate 25 spaced-apart holding jaws 21 and 23 which receive between them the striker holder 13 with the two locking wedges 11 and 12, as shown in FIG FIG. 3 is shown. This second coupling element 20 is connected to an in FIG. 2 schematically indicated B-pillar 2 of the vehicle body 1 is mounted, so that by closing the vehicle door 3, the striker holder 13 with the two locking wedges 11 and 12 between the two holding jaws 21 and 23 according to FIG. 3 passes and can be locked or coupled there with the second coupling element 20. For this purpose, the two holding jaws 21 and 23 each have a keyway 22 and 24 with wedge surfaces 22a and 24a, in the coupling and locking of the two coupling elements 10 and 20, the locking wedges 11 and 12 are pressed by means of the locking device 30, as for example . the FIG. 8a shows. The FIGS. 3 and 4 on the other hand show the first and second coupling element 10 and 20 in a decoupled state.

In order to facilitate the insertion of the locking wedge holder 13 with the two locking wedges 11 and 12 between the two holding jaws 21 and 23, the two holding jaws 21 and 23 in a point P by an angle α (eg. 3 °) with respect to a horizontal center line A is pivoted , so that the two splines 22 and 24 are conical to each other (see. FIG. 2 ). At this conical course of the two splines 22 and 24 and the side edges 11 a and 12 a of the two locking wedges 11 and 12 are adjusted.

To the locking wedges 11 and 12 for coupling the two coupling element 10 and 20 from its decoupled with the holding jaws 21 and 23 position according to the FIGS. 3 and 4 to move into a tensioned with their splines 22 and 23 position, the operative connection means 40 for establishing an operative connection between the strikers 11 and 12 and the drive device 30 in the striker holder 13 by means of a camshaft 42 mounted cam 41 with two diametrically opposed cam lances 41 a like this particular FIG. 1 is apparent. In the in FIG. 1 As shown, this cam 41 is in a position in which one of the two cam lugs 41 a formed straight line is directed parallel to the longitudinal direction of the two closing wedges 11 and 12, ie in the y direction, which is referred to below as 0 ° position ,

By a caused by the drive device 30 rotational movement of the cam plate 41 by 90 °, referred to as a 90 ° position, the cam lugs come 41a in contact with the two locking wedges 11 and 12 and press them against the spring force of two return spring elements 14, which the two locking wedges 11 and 12 according to FIG. 7b or 8b together, apart, so that they are simultaneously clamped in the keyways 22 and 24 of the holding jaws 21 and 23. By the two return spring elements 14, the two locking wedges 11 and 12 biased toward each other, so that by a rotational movement of the cam 41 back to its original position FIG. 1 or FIG. 7b the two strikers 11 and 12 are pulled out of their position clamped by the splines 22 and 24 in their decoupled position. In detail, the locking and unlocking operation will be explained below.

Due to the tension of the locking wedges 11 and 12 with the keyways 22 and 24 results in a positive connection between the two coupling elements 10 and 20 in the x and z direction and due to the conical shape of the two splines 22 and 24 in the y direction, and although in the direction of the vehicle interior. In the opposite y-direction, ie to the outside, a high adhesion occurs.

Thus, this positive engagement can be used to initiate forces from the B-pillar 2 in the vehicle door 3, when a corresponding door load path is established. For this purpose, according to FIG. 10 the active connection means 40 are accommodated in a housing 60, which has a load connection section 60a.

According to FIG. 11 the second coupling element 20 is mounted on a mounting surface 2 a of the B-pillar 2 of the vehicle body 1, while the first coupling element 10 is together with the housing 60 at a corresponding position in the vehicle door 3, wherein the load connection portion 60 a of the housing with a stiffening element 4 of Vehicle door 3 is connected to form a door load path. Below the coupled Clutch elements 10 and 20, a conventional vehicle lock can be arranged.

FIG. 20 shows an alternative embodiment of the second coupling element 20, which is mounted on a B pillar 2 of a vehicle body. In order to prevent the ingress of dirt into this second coupling element 20, the two holding jaws 21 and 23 are bridged by a movable cover 26, so that this cover from an open position, as in FIG. 20 shown, can be moved to a closed position.

In the following, the detailed structure of the coupling device 100 according to the invention will be described with reference to FIGS Figures 5 and 6 described.

To FIG. 5 is the closing wedge holder 13 cuboid formed with an H-shaped cross section, so that in each case between the H-legs, a closing wedge 11 and 12 can be accommodated. The closing wedges 11 and 12 are plate-like and have - as already described above - at their longitudinal edges 11 a and 12 a each two wedge surfaces 11 b and 12 b. In order to guide the closing wedges 11 and 12 in the striker holder 13, respective semicircular grooves 13a are provided on the striker holder 13 and semicircular grooves 11c and 12c on the striker 11 and 12, respectively, so that the hollow cylinders formed thereby can each receive a striker guide element 15 (FIG. see. FIG. 7b or 8b ).

According to FIG. 21 For example, the semicircular groove 11c of the closing wedge 11 and the length of the closing wedge guiding element 15 can be adapted to one another such that in the retracted state in the closing wedge holder 13, the upper end face of the closing wedge guiding element 15 is aligned with the closing wedge holder 13 on the face side. With the extension of the closing wedge 11 and the retraction of the shooting wedge 11 in the keyway 22 of the holding jaw 21 and the closing wedge guide member 15 moves as shown in FIG FIG. 22 out and in an adapted to this closing wedge guide element 15 semicircular groove 21a of the holding jaw 21 of the second coupling element 20 a (see. FIG. 23 ).

As a result, a positive connection between the two coupling elements 10 and 20 is also achieved in the y direction relative to the vehicle coordinate system. Such in the FIGS. 21 to 23 embodiment shown can also be provided for the opposite locking wedge 12 and the associated holding jaw 23.

In the transverse leg of the H-shape of the locking wedge holder 13 openings 13 b are provided, through which the two the locking wedges 11 and 12 connecting return spring elements 14 are passed. On the return spring elements 14 respectively elastic and sleeve-shaped Schließkeildämpfer14a are inverted to ensure a smooth retraction of the locking wedges 11 and 12 in the keyways 22 and 24.

For receiving the cam disk 41 arranged on the camshaft 42, the closing wedge holder 13 has a central bore 13c. The cam 41 is placed on a profiled end of the camshaft 42 and secured by a fixing screw 42 a.

Finally, the end faces of the closing wedge holder 13 are each covered with an end cap 13d.

In addition, one of the two closing wedges 11 or 12 can be formed with a closing nose 11 d or 12 d, as shown in FIG FIG. 19 is shown. Thereafter, this locking lug is perpendicularly centered on the side edge 11a and 12a, respectively, and therefore extends in the z-direction with respect to the vehicle-side reference system. This has the consequence that in the y direction both in the direction of the vehicle interior and in the outward direction a positive connection between the two coupling elements 10 and 20 is effected. It can also both closing wedges 11 and 12 are formed with such a closing nose 11d and 12d.

The axial arrangement along the camshaft 42, consisting of the striker holder 13, the panel 17 and a base plate 16 is held together by two mounting screws 18.

Starting from the base plate 16 to the drive device 30 shows FIG. 6 in an exploded view, the active connection means 40 for producing the operative connection between the drive device 30 and the closing wedges 11 and 12th

The cam plate 41 seated on the end of the camshaft 42 has already been described. The other end of this camshaft 42 protrudes through the base plate 16 and carries a non-rotatably connected to the camshaft 42 control disk 43, on the flange 43a, a drive pulley 48 is rotatably mounted. The control disk 43 and the drive pulley 48 are detachably connected via a pivotally arranged on the control disk 43 driver 46, which is designed as an angle lever. This driver 46 is mounted on the control disk 43 by means of a rotation axis 46a in such a way that a pin-shaped bolt 46b arranged at the end of a leg engages both in a detent 48a of the drive disk 48 and in a detent 43b of the control disk 43 under the spring force of a spring element 47 designed as a leg spring 47 is pressed.

A rotational movement of the drive disk 48 initiated by the drive device 30 causes a corresponding rotational movement of the control disk 43, wherein its rotational movement is essentially limited to a 90 ° angle range by a stop means 44 designed as a stop pin which cooperates with a circular arc-shaped control slot 43c of the control disk 43 is.

Further, a trained as a tension spring spring element 45 is provided, which is hinged at one end by means of a Einhängezapfens 45a with the base plate 16 and the other end via a Rückzugsseil 45c by means of a connecting pin 45b on the control disk 43. A rotational movement in the direction of rotation D1 causes a bias of the control disk 43 in the opposite direction of rotation.

A rotationally fixed coupling between the drive pulley 48 and the drive device 30 is accomplished by a clutch disc 49, which sits on the one hand on a flange 48b of the drive pulley 48 and engaging in driving holes 48c of the drive pulley 48 driving pin 49a rotatably connected to the same and on the other hand via a square axle formed connecting element 49b produces a rotationally fixed coupling with the drive device 30. This clutch disc 49 is mounted in a holding element 16 a, which is mounted on the base plate 16.

An emergency release lever 50 provided for an emergency unlocking function of the coupling device 100 rests flat against the base plate 16 and is longitudinally displaceable by means of the rotation axis 47a of the leg spring 47 guided in a guide slot 50a, wherein a limiting pin 50d is additionally arranged on the base plate 16 for longitudinal guidance.

Furthermore, one end of the Notentriegelungshebels 50 has an angled by approximately 90 ° flange 50c, which comes in a manually effected longitudinal displacement from a rest position in operative contact with the driver 46, wherein means of formed as a return spring spring element 51 of the emergency release lever 50 in the direction of its rest position is biased. This return spring 51 is connected at one end with a tab 50b at the other end of Notentriegelungshebels 50 and the other end by means of a Einhängezapfens 51 a with the base plate 16.

Below is the operation of the conventional operation of the previously described coupling device 100 will be explained, which is that when the vehicle door 3, so if the striker holder 13 with the strikers 11 and 12 between the two retaining wedges 21 and 24, depending on the vehicle speed automatically a Locking of the coupling device 100 by means of the motor drive device 30, for example. An electric motor takes place, d. H. that the two locking wedges 11 and 12 are pressed into the two splines 22 and 24 of the holding jaws 21 and 23 and thus the two coupling elements 10 and 20 are transferred into the coupled state. An equally motorized unlocking, ie a decoupling of the two coupling elements 10 and 20 takes place when an internal operating lever of the coupling device 100 is actuated and thereby the two locking wedges 11 and 12 are pulled by the return spring elements 14 of the keyways 22 and 24.

According to the FIGS. 7a and 7b are the two locking wedges 11 and 12 in their decoupled state, are therefore according to Figure 7a not clamped over their wedge surfaces 11b and 12b with the wedge surfaces 22a and 24a of the splines 22 and 24. In this case, the cam 41 is in the in FIG. 7b represented and designated as 0 ° position position corresponding to a first position of the control disk 43.

The decoupled state of the two coupling elements 10 and 20 corresponding first position of the control disk 43 is defined by the stop pin 44 abuts one end of the arcuate control slot 43c. Further, in this first position of the control disk 43, the same by means of the driver 46 rotatably coupled to the drive pulley 48, said driver 46 is biased by the leg spring 47 such that the latch 46b both in the detent 48a of the drive pulley 48 and in the detent 43b of the control disk 43 is pressed. The control disk 43 is biased by the tension spring 45 counter to the direction of rotation D1.

For locking the coupling device 100, the electric motor 30 is driven so that the drive pulley 48 moves in the direction of rotation D1, whereby the control disk 43 and thereby the cam 41 is moved in the same direction D1, ie in the direction of the 90 ° position. After a rotational movement of about 90 °, the stop pin 44 abuts the other end of the control slot 43 c, whereby the control disk 43 has reached a second position in which the locking wedges 11 and 12 through the cam lugs 41 a of the cam 41 into the keyways 22 and 24 of the two closing jaws 21 and 23 are pressed. Due to the non-rotatable coupling of the control disk 43 with the drive pulley 48, the drive pulley 48 can not continue to rotate, so that due to the rising motor current of the electric motor designed as a drive device 30 is turned off. Due to the self-locking of the electric motor 30, the tensioned tension spring 45 can not turn the control disk 43 back to its first position. This situation is in the FIGS. 8a and 8b shown. In the locked state of the coupling device 100, the electric motor 30 remains switched off; in the locked state is thus consumed by the Kupplungsvorrichtung.100 no electrical energy.

Receives the electric motor 30, a signal for unlocking the coupling device 100, this is controlled such that the drive pulley 48 moves counter to the rotational direction D1, so that due to the coupling with the control disk 43 from this from its second position to its first position Figure 7a is moved until, due to the restricted movement of the stop cam 44 movement of the control disk 43, the rising motor current of the electric motor 30 leads to its shutdown. Upon reaching the first position of the control disk 43, the cam disk 41 has in the 0 ° position according to Figure 7a turned back, thereby retracting the strikers 11 and 12 from the keyways 22 and 24 is effected due to the return spring elements 14. The two coupling elements 10 and 20 are thus decoupled again.

If the motor drive device 30 fails in the locked state of the coupling device 100, the emergency release lever 50, which is connected to an internal operating lever or a door handle of a conventional vehicle door lock, is used for emergency unlocking, as described with reference to FIGS Figures 9 will be explained below.

Starting from the coupled state of the two coupling elements 10 and 20 according to FIGS. 8a and 8b in which the control disk 43 is in its second position, the vehicle door 3 of the Notentriegelungshebels 50 is displaced in the direction of R1 by an operation of a door handle, so that thereby the angled flange 50c is pressed against the driver 46, which thereby against the spring force of Leg spring 47 pivoted from its detent position with the drive pulley 48 while the control disk 43 of the drive pulley 48 as shown FIG. 9a is decoupled. The control disc 43 is further rotated by this flange 50c until the latch 46b of the driver 46 is secure both from the detent 48a of the drive pulley 48 and from the detent 43a of the control disc 43 as shown FIG. 9a is disengaged.

The emergency release lever 50 is moved back by the return spring 51 back to its rest position and the spring force of the prestressed tension spring 45 takes over the further rotation of the control disk 43 whose first position in which the stop pin 44, the rotational movement at the end of the control slot 43 c terminated (see. FIG. 9b ). During this rotational movement to the first position, the latch 46b slides along the circumference of the drive pulley 48 and at the same time the cam disc 41 is rotated back from the 90 ° position to its 0 ° position in order to retract the strikers 11 and 12 from the keyways 22 and 24 of the holding jaws 21 and 23 to allow. The drive pulley 48, however, remains due to the self-locking of the electric motor 30 are in position over the entire operation of the emergency release.

After elimination of the fault of the electric motor 30, a motor locking of the coupling device 100 takes place in that the drive pulley 48 is driven by the electric motor 30 in the direction of rotation D1 until the detent 48a passes under the latch 46b, so that this both into the detent 48a of the drive pulley 48 as well as in the catch 43b of the control disk 43 can engage. Thus, the control disk 43 is again coupled to the drive pulley 48 and can be dragged by this again for locking in the second position.

In order to ensure a secure engagement of the bolt 46b in the detent 48a of the drive pulley 48, the detent 46b initially moves in the direction of rotation D1 into an abutment nose 48d projecting beyond the peripheral surface of the drive pulley 48, thereby locking the latch 46b prior to locking into the detent 48a is pivoted against the spring force of the leg spring 47.

All components of the first coupling element 10, which perform a control function, ie as the locking wedges 11 and 12, the control disk 43, the driver 46 and the Notentriegelungshebel 50 are biased by spring elements in the direction of its rest position corresponding to the decoupled state of the coupling device 100 and thus improving their reliability.

The FIGS. 12 to 18 show a further embodiment of the coupling device 100 according to the invention, according to FIG. 12 is shown in a side view. Thereafter, this coupling device 100 comprises a first coupling element 10 with a striker holder 13 for receiving strikers 11 and 12 and a housing 60 for receiving active connection means 40 for producing an operative connection between these strikers 11 and 12 and a motor drive device 30. The closing wedge holder 13 and the holding jaws 21 and 23 of the second coupling element 20 correspond in structure to those of the coupling device 100 described above according to the FIGS. 1 to 11 or the alternative versions of the FIGS. 19 to 23 ,

The FIG. 12 shows the coupling device 100 in the coupled state of the two coupling elements 10 and 20, in which the two locking wedges 11 and 12 are clamped over their wedge surfaces 11b and 12b with the wedge surfaces 22a and 24a of the splines 22 and 24 of the holding jaws 21 and 23, this from the motor drive device 30 is effected via a flexible shaft 87 connected to the housing 60.

The housing 60 is after FIG. 12 and FIG. 13 from a housing pot 61 a with an associated lid 61 b, according to the FIG. 12 a load-connection element 62 is screwed on the back side via a base plate 62a on the bottom part of the housing pot 61. Thus, this coupling device 100 according to the FIG. 11 be used for coupling a vehicle door with a B-pillar, so that via this coupling an introduction of force from the vehicle body is achieved in the vehicle door, when the load-connection element 62 of the first coupling element 10 is connected to a stiffening element of the vehicle door.

The from the housing 60 of the first coupling element 10 after FIG. 12 recorded operative connection means 40 shows FIG. 13 in an exploded view, which together with the Figures 14 and a functional first coupling element 10 performing FIGS. 15 to 17 will be described below.

These operative connection means 40 comprise components which correspond to those of the operative connection means 40 of the above-described coupling device 100 (cf. FIGS. 1 to 10 ) are identical or largely identical, and therefore only reference is made to this.

So is according to FIG. 13 also with a cam disk 41 arranged on a camshaft 42 at the end by a rotational movement initiated by the drive device 30 from a 0 ° position FIG. 15a in a substantially 90 ° position according to FIG. 15b or FIG. 15c a movement or retraction of the locking wedges 11 and 12 in the keyways 22 and 24 of the holding jaws 21 and 23 causes.

The cam 41 according to the Figures 13 and 15 is designed as a symmetrical two-sided lever with semi-circular ends as cam lugs 41 a.

The rotational movement of the non-rotatably connected to the camshaft 42 cam 41 is effected via a likewise non-rotatably connected to the camshaft 42 control disk 43, which has substantially the same geometry as that of the embodiment described above and also performs the same function. As already described above in connection with the first embodiment, the control disk 43 is detachably connected by means of a driver 46 with a drive pulley 48, which in turn rotatably connected to a driven by the drive device 30 worm gear, consisting of a worm wheel 81 comprising drive plate 80 and a screw 84, manufactures.

The coupling of the control disk 43 with the drive pulley 48 takes place by means of the driver 46 which is designed as a one-sided lever and which is pivotally mounted on the control disk 43 via an axis of rotation 46a and is pressed by a leg spring 47 into a position in which one is arranged at the other end Latch 46 b simultaneously engages in a detent 43 b of the control disk 43 and a detent 48 a of the drive pulley 48. FIG. 15a shows the decoupled state of the first coupling element 10, wherein the control disk 43 is in its first position and the two Locking wedges 11 and 12 are extended from the keyways 22 and 24 of the second coupling element 20, which corresponds to the 0 ° position of the cam 41.

The control disk 43 is connected to a tension spring 45 via a retraction cable 45c, this retraction cable 45c being connected at one end to the control disk 43 by means of a connecting pin 45b and at the other end being connected to the tension spring 45 arranged in a spring dome 90. How out FIG. 15a can be seen, the Rückzugsseil 45c from the direction of the spring dome 90, which is aligned perpendicular to the plane of rotation of the control disk 43, deflected by means of a bearing block 76 mounted in a guide roller 75 in this plane of rotation. By a rotational movement of the control disk 43 in the direction of rotation D1, the tension spring 45 is tensioned so that thereby a retraction force against the direction of rotation D1 acts on the control disk 43 and is rotated back to its first position when the coupling with the drive pulley 48 is released.

By realized by the driver 46 releasable coupling of the control disk 43 with the drive pulley 48 is at an initiated rotation thereof in the direction of rotation D1, the control disk 43 from its first position in which the cam 41 is in the 0 ° -layer, in the direction of her entrained second position while the cam disk 41 is rotated in the direction of its 90 ° position and thereby pushes the two locking wedges 11 and 12 in the keyways 22 and 24 of the holding jaws 21 and 23.

The drive pulley 48 is driven via the already mentioned worm gear, consisting of the drive plate 80 with worm wheel 81 and the worm 84. This screw 84 is rotatably mounted on a screw axis 84a and connected via a coupling 85 with the guided to the drive device 30 flexible shaft 87. A holder 86 serves to fix this arrangement.

The drive plate 80 consists of a worm wheel 81, which is in engagement with the worm 84, and a Federanbindungsrad 82, which produces a spring coupling between the drive wheel 48 and the worm wheel 81. A flange 81 a summarizes by means of fastening screws 81 b the said parts as a drive plate 80 together. This drive plate 80 is rotatably mounted on a flange 48b of the drive pulley 48 and is secured by a securing ring.

The spring coupling of the drive pulley 48 with the Federanbindungsrad 82 is based on the Figures 14 explained. The worm wheel 81 according to FIG. 14b has a circumferential sprocket facing towards in Figure 14a illustrated drive pulley 48 forms a flange which receives the Federanbindungsrad 82. The opposing radial surfaces of the drive pulley 48 and the Federanbindungsrades 82 each have two radially opposed circular arc-shaped grooves 48e and 48f and 82b and 82c, so that they can each pair a play compensation spring 83a and 83b accommodate between them. At the end, the circular-arc-shaped grooves 48e and 48f or 82b and 82c each have retaining lugs 48g and 82d, on which the clearance-compensating springs 83a and 83b are suspended. Thus, the play compensation spring 83a and 83b is connected at one end to the retaining lug 48g of the drive pulley 48 and the other end to the retaining lug 82d of the spring connection wheel 82.

A relative rotational movement of the Federanbindungsrades 82 relative to the drive pulley 48 to a maximum angle of rotation is made possible by means of a connecting pin 88 which is connected on the one hand via a receiving bore 48h fixed to the drive pulley 48 and on the other hand engages in a longitudinal groove 82a on the radial surface of the Federanbindungsrades 82nd This longitudinal groove 82a is bounded in each case by a semi-circular end surface adapted to the connecting pin 88, which limit the relative rotational movement of the drive pulley 48 and the spring connection wheel 82 and thus serve as a stop for the connecting pin 88.

This longitudinal groove 82a has a length which allows, for example, a relative rotational movement between the drive pulley 48 and the spring connection wheel 82 of, for example, 5 °.

A drive of the drive plate 80 in the direction of rotation D0 causes entrainment of the drive pulley 48 in the same direction of rotation D1 when the resulting spring force of the two play compensation springs 83a and 83b exceeds the frictional forces. When the rotational movement of the drive pulley 48 is stopped, the drive plate 80 rotates against the spring force of the play compensation springs 83a and 83b until the connection pin 88 abuts against one of the end abutment surfaces of the longitudinal groove 82a of the spring connection wheel 82.

This spring coupling is used for a during the coupled state of the two coupling elements 10 and 20 play compensation between the strikers 11 and 12 and this receiving keyways 22 and 24 of the holding jaws 21 and 23, as shown in the FIGS. 15 will be explained below.

As already described, shows FIG. 15a the decoupled state of the first coupling element 10, wherein the control disk 43 is in its first, defined by the stop pin 44 position. The relative position of the drive pulley 48 and the drive plate 80 is indicated by markers M1 and M2, respectively. The two marks M1 and M2 show no offset.

By appropriate control of the motor drive device 30, a rotational movement of the drive plate 80 in the direction of rotation D0 is effected via the flexible shaft 87 and the worm 84, so that the drive pulley 48 is entrained and the control disc 43 coupled to it is rotated from its first position in the direction of rotation D1, like this FIG. 15b is apparent. This turning process is according to FIG. 15b then finished, when the cam 41 has been rotated from its 0 ° position to an approximately 85 ° position, in which the two closing wedges 11 and 12 are already fully retracted into the splines 22 and 24 of the second coupling element 20. The control disk 43 is in an intermediate position shortly before its second position, in which the stop pin 44 is not yet abuts the control disk 43 at the end of the control slot 43c. The mark M1 and M2 are still aligned in this state of movement of the first coupling element 10. The drive plate 80 is further rotated by the drive device 30 beyond this state, indicated by the offset markings M1 and M2, until the maximum possible angle of rotation between the drive pulley 48 and the drive plate 80 is reached and thereby also the spring force of the two play compensation springs 83a and 83b a maximum value has risen. At the same time, a further rotational movement is blocked, as a result of which the motor current, for example, of the self-locking electric motor drive device 30 rises and leads to switching off of the electric motor 30. In the coupled state of the coupling device 100, the electric motor 30 remains switched off, due to the self-locking and a rotational movement of the worm wheel 81 of the drive plate 80 is prevented in the opposite direction of D0.

Due to the relative rotation of the drive plate 80 relative to the drive pulley 48, an offset between the two mark M1 and M2 is generated, as is apparent from FIG. 15c is apparent. Thus, the drive pulley 48 is biased in the direction of rotation D1. Now occurs in the coupled state of the two coupling elements 10 and 20 between the locking wedges 11 and 12 and the keyways 22 and 24 a game on, press the play compensation springs 83a and 83b the drive pulley 48 further in the direction of rotation D1, whereby the control disk 43 in the same Directed rotation D1 and at the same time the cam 41 is further rotated in the direction of the 90 ° position and thereby compensate for the locking wedges 11 and 12 of this game.

For motor unlocking of the two coupling elements 10 and 20, this process takes place in the opposite direction, ie the drive device 30 is driven in such a way that the drive plate from the position according to FIG. 15c is moved in opposite to the direction of rotation D0 until the state according to FIG. 15a is reached again.

In order to enable unlocking of the two coupled coupling elements 10 and 20 despite failed or defective drive device, one of the below with reference to the Figures 13 . 16 and 17 explained emergency release function. With this emergency unlocking function, the coupling device 100 can be unlocked mechanically or manually not only in the already locked state, but also if during the Verrieglungsvorganges or unlocking the drive device 30 fails or regarding the same problem occurs and the cam 41 in such a case in the range from the 0 ° position to the 90 ° position can be.

This emergency unlocking function is realized by means of a rotatably mounted on a flange 46a of the control disk 46 and engageable with the driver 46 in an operative release unlocking ring 70 and mounted in a bearing block 74 by means of a rotation axis 74a Zahnsegmentrad 71, which according to FIG. 16a via a toothed segment 71a with a toothed segment 70b of the unlocking ring 70 produces a rotary connection.

The unlocking ring 70 has a control cam 70a which, upon pivoting of the unlocking ring, comes into contact with the driver 46 from a rest position counter to the direction of rotation D1, the latch 46b of which locks with the catch 43b of the control disk 43 as well as with the detent 48a of the drive disk 48 is (cf. FIGS. 16a and 17a ).

A pivoting of the unlocking ring 70 from its rest position is effected by means of the toothed segment wheel 71, which by means of a on a Flange 71 b of the toothed segment wheel 71 mounted leg spring 72 is held in a rest position of the unlocking ring 70 corresponding first pivot position. To decouple the control disk 43 from the drive pulley 48, the toothed segment gear 71 is connected by means of a connecting pin 73a with a pull cable 73, which is guided at its other end a door handle of the vehicle door, so that by an operation of this door handle the Zahnsegmentrad 71 against the spring force of the angle spring 72 is pivoted from its first pivot position in the direction of rotation D2 in a second pivot position, which is pivoted due to the gear segment translation of the unlocking ring 70 against the direction of rotation D1 in an operating position and thereby raises the latch 46b from the detents 43b and 48b, as the FIG. 16b shows, and then in contact with the driver 46, the control disk 43 is further pivoted against the direction of rotation D1 with entrainment of the cam 41 in the direction of its 0 ° position. Out FIG. 17b It can be seen that the drive pulley 48 remains in the position corresponding to the lock in both coupling elements 10 and 20. Furthermore, the toothed segment wheel 71 is rotated back by the leg spring 72 in the rest position corresponding to the unlocking ring 71.

Out of this in FIG. 17b shown uncoupled from the drive pulley 48 position of the control disk 43, this is withdrawn from the arranged in the spring dome 90 tension spring 45 in its first position, so that accordingly FIG. 17c the cam 41 has reached its 0 ° position.

The geometry of the control cam 70a is adapted to the geometry of the driver 74 as a one-sided lever, that each position of the control disk 43 each represents an operating position of the unlocking ring 70, in each of which by means of the Zahnsegmentrades 71 decoupling of the steering wheel 43 is effected by the drive wheel 48 , This is between the first position of the control disk 43, which corresponds to the decoupled state of the two coupling elements 10 and 20 and their second position, which corresponds to the coupled state of the two coupling element 10 and 20, by means of the control cam 70a, a decoupling of the control disk 43 causes from the drive pulley 48, even in the first position of the control disk 43 which corresponds to the 0 ° position of the control disk 41.

Instead of the toothed segment wheel 71 can also be used a sliding rack, which is mechanically connected to the door handle of the vehicle door. Upon actuation of the door handle, the rack is displaced so that it moves against the direction of rotation D1 due to the tooth engagement with the unlocking ring 70 and thereby the driver 46 is pivoted out of the detents 43b of the control disk 43 and 48a of the drive disc 48.

After the elimination of a defect with respect to the drive device 30, after a manually carried out unlocking, that is, after a decoupling of the two coupling elements 10 and 20, a motorized locking must again be effected. This process is based on the Figures 18 explained.

Starting from the in FIG. 17c state shown, the drive device 30 is driven such that the not coupled to the control disk 43 drive pulley 48 continues to rotate in the direction of rotation D1 until the catch 48a, the bolt 46b moves underneath, thereby allowing it to engage in the notches 48a and 43b.

The state just before underrunning the latch 46b by the latch 48a shows FIG. 18a , Before the latch 46b falls under the action of the leg spring 47 in the detents 48a and 43b, the latch 46b is first raised by a lifting lug 48d of the drive pulley 48 against the spring force of the leg spring 47. The locked in the detents 48a and 43b state of the bolt 46b of the driver 46 shows FIG. 18b , Thus, in the first position located control disk 43 is back to the drive pulley 48 coupled and can now for re-locking in the Figure 17a corresponding second position be dragged.

Also, this coupling device 100 according to the FIGS. 12 to 18 has the property that all components of the first coupling element 10, which exert an actuating function are biased by spring elements in the direction of its rest position, which corresponds to the decoupled state of the coupling device 100.
