Description

The invention relates to a coupling device for the releasable connection of a pivotably mounted body part, in particular a vehicle door, tailgate or front flap, to a vehicle structural part of a vehicle body according to the preamble of patent claim 1.

A generic coupling device is based on the applicant DE 10 2012 011 420 A1 is known and comprises a first, with two mutually displaceably mounted locking wedges with wedge surfaces coupling element and a cooperating with this second coupling element, wherein in the coupled state of the coupling device via adjacent wedge surfaces, the first and second coupling elements are coupled without play. The second coupling element is formed with two splines, the first coupling element between the holding jaws having wedge surfaces, so that by means of a motor drive device, the locking wedges are pressed apart by their wedge surfaces into the splines, bearing against their wedge surfaces.

To move the locking wedges into the coupling position, the first coupling element has a cam disk with two diametrically opposite cam lugs, so that the locking wedges are pressed into the keyways by the cam lugs by rotation. To move the locking wedges from the coupling position into the non-coupling position, two return spring elements connecting the locking wedges are provided, which prestress the two locking wedges in the direction of the non-coupling position.

Due to the passive adjustment of the two locking wedges from the coupling position to the non-coupling position, there is a risk that the locking wedges get stuck in the locking wedge holder in the coupling position due to dirt or freezing and can therefore no longer move into the non-coupling position.

Furthermore, from the DE 200 03 277 U1 a coupling device is known which consists of a lock with two locks which can be displaced parallel to one another between an open and closed position, and when these locks are moved into their closed position they cooperate with a counterpart in a positive and / or non-positive manner for locking purposes. In order to move these bolts between their open and closed positions, a rotatable lock disc is provided as a control disc, which establishes an operative connection with the bolts via crank drives. By turning the lock disc, the two bolts are moved between the open and closed positions.

A disadvantage of this known coupling device is the high design effort for the crank mechanisms for moving the latch.

After all, is out of DE 198 30 270 A1 a holder for a mobile phone with a support plate and with two jaws arranged on the long sides of the support plate, which are displaceable and adjustable in opposite directions to one another in the transverse direction of the support plate via a gear-type coupling element. The clamping jaws are designed with pins which engage in spiral profile curves of a profile disk rotatably mounted on the support plate as a control disk. With such a profiled disc, a stepless tightening and loosening of the clamping jaws is made possible, so that the clamping jaws are fixed in every position and without a locking is necessary.

The object of the invention is therefore to provide a coupling device of the type mentioned at the outset, in which the locking wedges are prevented from becoming stuck in the locking wedge holder in the coupling position.

This object is achieved by a coupling device with the features of patent claim 1.

In the in 1 shown non-coupling position I are the two wedges 11 and 12 each on the guide element 16 with the control pin 11.2 of the striker 11 yourself in the beginning 14:10 the tax groove 14.1 and the control pin 12.2 of the striker 12 at the beginning 14:20 the tax groove 14.2 located. When the control disc rotates by 90 ° 14 in one direction D1 the two control pins 11.2 and 12.2 along the control grooves 14.1 respectively. 14.2 positively driven so that hereby the two locking wedges 11 and 12 can be moved apart in opposite directions in the z-direction, since these are in the striker holder 13 can only be moved in the z direction. The tax slots 14.1 and 14.2 are arched, the ends of which form a center angle of 90 ° and the radial distance from the beginning 14:10 respectively. 14:20 until the end 14:11 respectively. 14:21 increases continuously. The difference between the radial distance from the beginning 14:10 respectively. 14:20 the tax groove 14.1 respectively. 14.2 and the end 14:11 respectively. 14:21 corresponds to the displacement of the striker 11 respectively. 12 , After turning the control disc 14 by 90 ° starting from the non-coupling position I of the two locking wedges 11 and 12 the control pins are in the corresponding position 11.2 and 12.2 at the end of the tax groove 14:11 respectively. 14:21 how this is the 3 shows.

When the control disc rotates 14 from the coupling position II the wedges 11 and 12 corresponding position according to 3 in to the direction of rotation D1 opposite direction of rotation D2 the wedges become 90 ° 11 and 12 about that in the tax groove 14.1 and 14.2 positively driven control pin 11.2 and 12.2 back to the non-coupling position I according to 1 relocated.

The strikers 11 and 12 are each on their free faces to form two wedge surfaces 11.1 and 12.1 formed with a symmetrical wedge-shaped cross section.

The second coupling element 20 to 2 includes two on a base plate 25 spaced-apart holding jaws 21 and 23 holding the wedge holder between them 13 with the two locking wedges 11 and 12 take up. This second coupling element 20 is at one in 2 schematically indicated mounting surface 2.1 a B-pillar 2 the vehicle body 1 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 arrives and there with the second coupling element 20 can be locked or coupled. For this purpose, the two holding jaws 21 and 23 one keyway each 22 respectively. 24 with wedge surfaces 22.1 respectively. 24.1 on, for coupling and locking the two coupling elements 10 and 20 the wedges 11 and 12 by means of the drive device 30 from the non-coupling position I according to 1 in the coupling position II according to 3 be pressed.

By tightening the locking wedges 11 and 12 with the keyways 22 and 24 there is a positive connection between the two coupling elements 10 and 20 in the x and z directions and due to the conical shape of the two keyways 22 and 24 also in the y direction, in the direction of the vehicle interior. In the opposite y-direction, i.e. towards the outside, there is a high adhesion.

This form fit can be used to generate forces from the B-pillar 2 into the vehicle door 3 to initiate when a corresponding door load path is established, as in the above DE 10 2012 011 420 A1 is described.

The 4 . 5 and 6 show a specific embodiment of a striker holder 13 with locking wedges 11 and 12 by a control disc 14 between the non-coupling position I according to 5 and the coupling position II according to 6 are positively guided, the control disc 14 over an axis of rotation 15 that have active compound 40 with the drive device 30 , for example. An electric drive is rotatably connected.

This wedge holder 13 has approximately a cuboid outer contour, the one receiving space 13.1 for the upper striker 11 and another recording room 13.2 for the lower striker 12 has, so the two strikers 11 and 12 starting from a guide element 16 in the z direction against each other between the non-coupling position I and the coupling position II can be moved.
