Description

Door system for a vehicle and vehicle with a door system

The present invention relates to a door system for a vehicle, in particular for a rail vehicle, comprising a door leaf which can be moved from a closed state to an open state and vice versa. In this case, the door system comprises a longitudinal member extending along a longitudinal axis of the vehicle, having a longitudinal guide in which the door leaf is movably guided. In addition, the door system includes a vehicle-mounted cross member, which extends along a vehicle transverse axis essentially perpendicular to the longitudinal member, the longitudinal member being movably guided via a guide device in a transverse guide of the cross member. Furthermore, the door system comprises a locking device which is designed to block a relative displacement between the cross member and longitudinal member in a locking position and to release a displacement of the cross member relative to the longitudinal member in an open position.

The present invention relates in particular to pivoting sliding door systems, both to door systems with one door leaf and to door systems with two door leaves, the so-called two-leaf pivoting sliding door systems. In the said closed state, a door portal formed on the vehicle is closed by the door leaf(s), so that passenger boarding (this is to be understood as meaning getting into or out of the vehicle) is prevented. In the open position, the door leaf or leaves are in a position in which the door portal is largely released (i.e. opened) for passenger boarding. The opening and closing movement of the door leaves is realized via an electro-mechanical drive device.

As a rule, such door systems have a locking device, by means of which a secure locking of the door leaves (in particular in their closed position) is ensured. This is necessary, for example, to counteract unintentional opening of the door leaves while driving. This is because during ferry operation of a vehicle having such a door system, due to forces acting on the door system or the door leaves (e.g. resulting from bumps in the roadway, acceleration or cornering) Movements of the door leaves result, which in the worst case can lead to an unintentional opening of the door leaves during ferry operation. Furthermore, jamming or displacements of the door leaves can result from such relative movements.

It is known from the prior art to lock door leaves via a stroke in strikers, self-locking drives, locks on the portal or motor brakes. More modern locks lock the door system using rotating columns, lockable swivel arms or rotary latch locks. Many of the systems mentioned fall back on dead center bearings.

The known systems often lack adequate protection against vibrations or shocks. Furthermore, the known systems generally cannot be locked far beyond a dead center position, since the door leaves can be moved relatively easily in the opening direction by means of a reversing movement carried out in the process. Furthermore, in known locking devices, a higher force is required to overcome the dead center than to produce the required sealing dimensions. Last but not least, the production, assembly and commissioning of the known locking systems are associated with relatively high costs.

Accordingly, the present invention is based on the object of providing a door system of the type mentioned at the outset, which is more cost-effective than the known systems and meets higher safety standards when locking. The same task is subject to the guideway also claimed with the invention.

The aforementioned object is achieved by a door system with the features of claim 1 and a track with a door system designed according to the invention according to claim 19.

It should be pointed out that the features listed individually in the claims can be combined with one another in any technically sensible way (even across category boundaries, for example between device, use and method) and further refinements of the invention point out The description additionally characterizes and specifies the invention, in particular in connection with the figures.

It should also be pointed out that a conjunction "and/or" used herein, standing between two features and linking them to one another, must always be interpreted in such a way that in a first embodiment of the subject matter according to the invention only the first feature can be present, in a second embodiment only the second feature may be present and in a third embodiment both the first and the second feature may be present.

According to the invention, a door system for a vehicle, in particular for a rail vehicle, is proposed, comprising a door leaf which can be moved from a closed state into an open state and vice versa, the door system comprising a. a longitudinal member extending along a vehicle longitudinal axis, having a longitudinal guide in which the door leaf is movably guided; b. a crossmember fixed to the vehicle, which extends along a vehicle transverse axis essentially perpendicularly to the longitudinal member, the longitudinal member being movably guided via a guide device in a transverse guide of the crossmember; c. a locking device which is designed to block a relative displacement between the longitudinal and cross members in a locking position and to release a displacement of the longitudinal member relative to the cross member in an open position.

The door system is characterized in that the locking device comprises a locking disc which is pivotably mounted on the guide device, the locking disc when unlocking the locking device using a drive device operatively connected to the locking disc and performing an unlocking pivoting movement from a first end position up to can be pivoted to a second end position, and wherein the longitudinal member and the cross member are fixed relative to one another when the unlocking pivoting movement is carried out over a predetermined idling angular amount of the locking disk. A locking device designed according to the invention is characterized in particular by its low installation space requirements, which is why it can be characterized as particularly space-saving. Furthermore, a drive device that is already present on most door systems can be used to operate the locking device, which simplifies the construction and assembly of a door system according to the invention.

As already mentioned at the outset, a door system designed according to the invention is particularly suitable for implementation or use in vehicles. A “vehicle” can in particular be a rail vehicle, for example a streetcar, subway, tram, suburban train, a

A regional train, a long-distance train or another rail-bound means of passenger transport are understood. A "vehicle" within the meaning of the invention can also be understood to mean a wheeled means of passenger transport, for example a bus. In principle, a door system according to the invention can also be used in other vehicles, such as aircraft or ships, as long as they have a door system.

Said longitudinal member is in particular made of metal, a load-resistant plastic or a composite material and has a longitudinal guide that extends at least over a partial length of the longitudinal member. The guide can also extend over the entire length of the longitudinal member. The door leaf is movably guided in the longitudinal guide. In the case of a double-leaf pivoting sliding door, both door leaves can be guided in the longitudinal guide. At the same time, two separate longitudinal guides can be formed in the longitudinal beam in the case of a two-leaf pivoting sliding door, one of the door leaves then being movably guided in each of the longitudinal guides. The door leaf or leafs can be guided via suitable support structures, the specific design of which, however, is not the subject of the present invention. The longitudinal guide can be designed in the form of a guide channel, a guide groove, a guide groove or a guide rail. The longitudinal guide can interact with a roller-bound or slide-bound support structure, wherein the support structure on the one hand is attached to the door leaf and on the other hand is guided in the longitudinal guide.

As mentioned, according to the invention, a cross member is provided which extends along a vehicle transverse axis essentially perpendicularly to the longitudinal member. In a double-leaf pivoting sliding door system, two crossbeams can be provided and arranged opposite one another. A "substantially vertical" arrangement is to be understood as meaning manufacturing or assembly-related tolerances that can lead to a slight deviation in an arrangement angle of 90° between the longitudinal and cross member. The cross member has a transverse guide in the form of a guide channel, a guide trough, a guide groove or a guide rail. The mentioned guide device is connected on the one hand to the longitudinal member and on the other hand it is movably guided or mounted in the transverse guide Coupling to the longitudinal member—to an entrainment of the longitudinal member and thus to a transverse movement of the longitudinal member in relation to the cross member.

As mentioned, a door system according to the invention includes a locking device. This can assume both a locked position and an open position. In the locking position, the locking device blocks a relative displacement between the cross member and the longitudinal member. However, "blocking" in this context does not mean that the transverse and longitudinal beams are arranged completely rigidly with respect to one another in the locking position of the locking device. There can certainly be play between the components, i.e. a slight relative movement. In the open position The locking device allows the cross member to be moved, in particular displaced, relative to the longitudinal member. If the locking device is in its open position, the door leaves can be opened by means of a pivoting sliding movement. However, the locking device ensures that the door leaves are secured against unintentional opening when they are closed . According to the invention, the locking device comprises a locking disk which is pivotably mounted on the guide device. The pivot bearing is designed in such a way that the locking disk can be pivoted about a longitudinal axis aligned parallel to the longitudinal member. When the locking device is unlocked, the locking disk is pivoted from a first end position to a second end position, ie rotated about said longitudinal axis, using a drive device operatively connected to the locking disk, performing an unlocking pivoting movement. When the unlocking pivoting movement is carried out, the longitudinal beam and the crossbeam are fixed relative to one another over a specified idle angle of the locking disk, i.e. over a specified pivoting angle of the locking disk about the longitudinal axis (idle angle) there is no relative displacement between the longitudinal and crossbeams, but an idle . Thus, during idling, the locking disk rotates freely, which can be used, for example, to drive additional locking elements or other components via the drive device. In the case of a two-leaf pivoting sliding door system, the locking device can be designed redundantly, ie a locking device can be provided for each of the door leaves between the two crossbeams and the longitudinal beam. The locking disks, which are provided twice in this case, can be set in a pivoting movement (eg the aforementioned unlocking pivoting movement) via a common drive device. This is preferably done simultaneously and synchronously.

A relative movement, ie relative displacement between the longitudinal member (including the door leaves guided therein) and the cross member only takes place when the locking disk is pivoted by an amount exceeding the idling angle amount. In the reverse process, ie when locking, the locking disk is pivoted in a direction opposite to the unlocking pivoting movement, namely from the second end position in the direction of the first end position. Here, too, the idling angle amount must be overcome before the first end position is reached. The advantageous configurations specified in the dependent claims and further advantageous (or possible) configurations of the door system proposed with the invention are described in detail below.

According to a first embodiment of the invention, it can be provided that the locking disk for locking the locking device can be pivoted using the drive device and executing a locking pivoting movement starting from the second end position to the first end position. The pivoting movement mentioned relates to the reversal movement of the locking disk in relation to the unlocking described above. The pivoting direction of the locking disk when locking is opposite to the pivoting direction when unlocking. The drive device is therefore able to turn or rotate the locking disk in two pivoting directions.

According to a further embodiment of the invention, it can be provided that the locking disk has a curved elongated hole opening, in which a non-displaceably arranged guide element on the crossbeam is at least partially accommodated and guided. A slot opening is to be understood as meaning that the opening (this can be, inter alia, a material cut-out or cut-out) has a greater length than width extension. It is advantageous here that the slot opening does not extend over the entire locking disk, but is formed in a partial section of the locking disk. The slot opening extends primarily in a plane of the locking disk that is transverse to the longitudinal direction of the vehicle. The locking disk is preferably made of metal, a mechanically stable plastic or a composite material. An "at least partial inclusion" of a guide element can be understood to mean that the guide element protrudes partially or completely into the slot opening. The guide element can be adapted in its largest cross-sectional diameter to the inner diameter of the slot opening. The largest cross-sectional diameter can also be smaller than the inner diameter of the slot opening.The guide member may be lubricated with a lubricant opposite the slot opening to avoid unnecessary friction.The guide member may have a round (e.g. circular) or rounded cross-section.For example, the guide member may be in the form of a be formed rounded bolt or pin. A spherical shape of the guide element can also be considered. The guide element is mounted or flanged on the cross member so that it cannot rotate or move. The guide element can also be welded to the cross member. The guide element can therefore be an integral part of the cross member, or an additional component connected to the cross member. Since the guide element is guided in the slot opening, the position of the guide element in relation to the slot opening can be changed by pivoting the locking disk. The guide element therefore slides along the elongated hole opening when the locking disk is pivoted. Since the guide element is fixed to the vehicle (due to the design or attachment to the cross member), the slot opening actually slides (this is moved by pivoting the locking disk) in relation to the guide element. A curved design of the elongated hole opening is to be understood as meaning that it extends over its length in the manner of a curved path over the locking disk. A curved path can be understood, for example, as a circular path, an arcuate path, an elliptical path or some other curved path. According to the invention, the cam track undergoes at least one change of sign. The slot opening is designed in such a way that a continuous movement in the transverse direction of the vehicle is generated by sliding along the guide element.

According to a further embodiment of the invention it can be provided that the guide element is positioned in the locking position in a first end position in the region of a first slot end. The guide element can rest with an outer section on the first end of the slot (i.e. be supported against the inner circumference of the slot) or be positioned in its immediate vicinity.

According to a further embodiment of the invention, it can be provided that the slot opening is designed in such a way that the locking disk is displaced relative to the guide element when it is pivoted by the idling angle in such a way that the guide element changes position from the first end position to a latching position , whereby the detent position is a position in the area of the center of the elongated hole. Advantageously corresponds to the Change of position of the guide element from the first end position to the locking position in about half the path length of the slot opening. The "idle angular amount" means that the locking disk does not cause any relative movement between the crossbeam and longitudinal beam when pivoting through an angle that leads to the stated change in position between the guide element and slot opening (from the first end position to the latching position). is actually an idle state. In the detent position, the locking disk is in a position similar to a dead center. In this position, it is not possible to move the longitudinal member relative to the cross member. The door system is therefore in any position of the locking disk in which the locking disk is not pivoted beyond the idling angle, is arrested or locked. Only by further pivoting of the locking disk (beyond the idling angle) is a relative movement between the cross member and longitudinal member made possible. Further pivoting of the locking disk (beyond the idling angle ) can be effected by the drive device become T.

In the locking position, the locking disk is arranged in an over-center position, while the locking disk is arranged in a position corresponding to the locking position of the guide element in the elongated hole opening in a dead-center position. Correspondingly, in the dead center position, the runner plate coupled to the locking disk is prevented from shifting relative to the cross member. This can only take place when further driving force is applied, with further pivoting of the locking disk.

According to a further embodiment of the invention, it can be provided that the elongated hole opening is designed in such a way that the locking disk is displaced relative to the guide element when the locking disk is pivoted beyond the idling angular amount in such a way that the guide element can change position from the latched position via an intermediate position in the Area of a second slot end experiences up to a second end position in the center of the slot. As already mentioned, such a further pivoting can result in a relative movement between the cross member and the longitudinal member. The guide device, which is movably guided in the transverse guide of the crossbeam, experiences a relative displacement with respect to the stationary crossbeam and takes the side member with it. During the reversal process of locking, the position of the guide element changes from the second end position (in the area of the middle of the slot) via the intermediate position (in the area of the second end of the slot) to the locking position. The locking disk is pivoted (via the drive device) in a direction that is opposite to the pivoting direction during the unlocking pivoting movement. There is therefore a locking pivoting movement. After reaching the locking position of the guide element and a subsequent pivoting in the direction of the locking pivoting movement, the transition to an idle state occurs when a predetermined locking pivoting angle is exceeded, so that there is no longer any relative movement between the cross member and longitudinal member. The locking pivoting angle and the idle pivoting angle add up to a total angle through which the locking disk can be pivoted by means of the drive.

According to a further embodiment of the invention, it can be provided that the second end position of the guide element (in the region of the middle of the elongated hole) relative to the locking disk corresponds to the locking position of the locking device. In this position, no further pivoting of the locking disk can take place in a pivoting direction corresponding to the unlocking pivoting movement. Pivoting of the locking disk in the direction of the locking position must be brought about by the drive device, ie it is blocked by the drive.

According to a further embodiment of the invention, it can be provided that the guide device has a guide rail which is accommodated at least in sections in a guide bushing of the longitudinal member, and the guide rail is connected in a non-displaceable and non-rotatable manner to a runner plate which is connected to a running device in the transverse guide of the Cross member is slidably mounted. The guide bar extends essentially along the longitudinal axis of the vehicle, that is to say along an axis running parallel to the side member. The main extension direction of the runner plate, on the other hand, runs perpendicularly to the guide rail, ie in a direction parallel to the cross member. The non-displaceable and non-rotatable connection of the guide rail to the runner plate can be realized, for example, by means of a screw connection. Other fastening variants are also conceivable, for example a riveted connection, welded connection, etc.

The running device can be designed, for example, in the form of two running rollers connected to the running plate, the running rollers being accommodated and movably guided in the transverse guide of the crossbeam. According to an advantageous embodiment, the guide bar can be connected to the runner plate and the runner device via a threaded bolt. The threaded bolt can have an external thread and can be screwed into or engage in a threaded opening formed on the guide rail, the threaded opening having an internal thread that corresponds to the external thread of the threaded bolt. The threaded bolt and the threaded opening provided on the guide bar extend parallel to the longitudinal member. The runner plate can be clamped between an end of the guide rail facing the crossbeam and a threaded bolt head. Furthermore, a connection element for fastening the running device can be provided on the threaded bolt head. In the case of a double-leaf pivoting sliding door system, the longitudinal member has a guide bushing at each of its two ends for receiving a respective guide rail. The above-described arrangement of guide bushing, guide bar, runner plate and running device (and their attachment via a threaded bolt) is therefore provided twice in a double-leaf pivoting sliding door system.

According to a further embodiment of the invention, provision can be made for the locking disk to be rotatably mounted on an external partial section of the guide bar. For this purpose, the locking disk can have a hole opening, the inside diameter of which is adapted to the outside diameter of the guide bar, so that the locking disk can be rotatably mounted on the guide bar. In the longitudinal direction, the locking disk mounted on the guide bar is delimited on the one hand by the longitudinal member and on the other hand by the runner plate, so that a longitudinal displacement of the locking disk over the guide bar is avoided. According to a further embodiment of the invention, it can be provided that the guide bar and the runner plate connected to it provide a driver arrangement for the longitudinal member, which is set up to entrain the longitudinal member when the driver arrangement is displaced relative to the cross member. When unlocking, the guide device, in particular the runner plate, can be displaced in the transverse guide over the runner device when the locking disk is pivoted beyond the idling angular amount. The non-rotatable connection between the running device, runner plate, guide bar and longitudinal member ensures that the longitudinal member is carried along when the running device, together with the components connected to it, is moved transversely along the transverse guide.

According to a further embodiment of the invention, it can be provided that the locking disk is arranged between the longitudinal member and the cross member, and that the runner plate is arranged between the locking disk and the cross member. It can also be advantageous if the components mentioned are detachably fastened in order to be able to replace individual components in the event of maintenance or in the event of damage. A detachable connection also facilitates installation in existing door systems, which can be retrofitted in this way with the construction according to the invention.

According to a further embodiment of the invention, it can be provided that the slot opening extends in an arc, in particular in the shape of a boomerang, over a section of the locking disk. The specified geometric shape description refers to a course of the slot opening in a vertical plane extending parallel to the cross member (perpendicular to the longitudinal member), or to a top view of the locking disk. An arcuate extension means that the elongated hole opening does not necessarily have to extend along a geometric partial circular shape, ie the curved extension does not have to have a constant radius—relative to a fictitious center point—this can be variable. A boomerang-shaped extension of the elongated hole opening can be in the form of elongated hole legs arranged at an angle in relation to the center of the elongated hole express, the elongated hole legs are preferably angled at the same angle to the middle of the elongated hole.

As already indicated, according to a further embodiment of the invention it can be provided that the idling angular amount leads to a change in position of the guide element relative to the locking disk (or the slot opening of the locking disk relative to the guide element) from the first end position in the region of the first slot end to the latching position in the area of the middle of the elongated hole. Pivoting the locking disk around a longitudinal axis of the guide rail (the locking disk is mounted on the guide rail) by the idling angular amount leads to the stated change in position between the guide element and the slot opening (from the first end position to the latching position).

According to a further embodiment of the invention, provision can be made for toothing to be arranged on the locking disk, into which toothing a drive element, in particular a drive wheel, engages. The toothing arranged or formed on the locking disk is preferably arranged on an outer peripheral section of the locking disk. By the engagement of the toothing of the drive element in the toothing of the locking disk, an opposite rotation or pivoting of the locking disk can be generated by rotating the drive element. The door system can thus be unlocked and locked via the drive element (this is connected to the drive device, for example via a linkage). The rotational movements of the drive wheel and the locking disk performed during unlocking and locking are in opposite directions.

According to a further embodiment of the invention, it can be provided that the locking disk and the drive element are rotatably mounted on mutually parallel axes of rotation, which proves to be particularly space-saving. In a double-leaf pivoting sliding door system, a drive element is provided in the area of both ends of the longitudinal member in order to be able to set the respective locking disks in rotation. The drive elements can be operated via a common linkage and a common drive or via separate drives (including linkage). According to a further embodiment of the invention, it can be provided that, in relation to a vehicle transverse plane (meaning a vertical plane) running parallel to the cross member and perpendicular to the side member, the center point of an imaginary section of a circle, which extends along a leg of the long hole directly adjoining the first end of the long hole, with coincides with the axis of rotation of the locking disc. Such an arrangement enables the idling described. Pivoting the locking disk, starting from the first end position, by the idling angular amount therefore has no effect on any displacement of the runner plate connected to the locking disk along the cross member.

According to a further embodiment of the invention, it can be provided that the locking device is designed and arranged in such a way that when the locking disk is pivoted by the idling angular amount, a spatial arrangement of the axis of rotation of the drive element, the axis of rotation of the locking disk and an axis of symmetry of the guide element is constant to one another. This means that during a displacement of the locking disk by an angle of rotation that is in the range of the idling angular amount, there is no relative position displacement of the axes mentioned. This ability to arrange or property of the axes mentioned allows a dead center like positioning of the locking disk when it reaches the guide element in the detent position. Furthermore, this enables an over-center position of the locking disk when the guide element is positioned in the first end position (in the region of the first slot end).

According to a further embodiment of the invention, it can be provided that the guide element is a guide cam or guide pin. The guide cam or guide pin may be flanged to, welded to, or otherwise attached to the cross member. The guide cam or guide pin can be bolt-like, ie have a round cross-section. The guide cam can also be accommodated in an opening in the cross member or screwed to it so that it cannot move. As mentioned at the outset, the object on which the invention is based is also achieved with a vehicle having a door system according to the invention.

Further features and advantages of the invention emerge from the following description of a non-limiting exemplary embodiment of the invention, which is explained in more detail below with reference to the drawing. In this drawing show:

5-8 in schematic views the unlocking process of a door system according to the invention using a locking device as part of a door system according to the invention.

FIGS. 1 and 2 show a section of a door system according to the invention in a first and second perspective view. Shown is a section of a longitudinal member 1 of a pivoting and sliding door system, which extends along a vehicle longitudinal axis X, and in whose longitudinal guide two door leaves are slidably mounted (not shown). The examples shown in the figures are two-leaf Pivoting sliding door system, ie all of the components shown in the detailed views (e.g. FIGS. 1 to 3) are provided at both ends of the longitudinal member 1 (cf. FIG. 4).

As shown in FIGS. 1 and 2, a cross member 2 having a transverse guide 4 is arranged transversely to the longitudinal member 1 . The cross member 2 extends along a vehicle transverse axis Y. As can be seen from FIG. 4, two cross members 2 are provided in the exemplary embodiment shown here. The cross members 2 are attached to the vehicle, ie arranged fixed to the vehicle. The longitudinal beam is movably guided in the transverse guides 4 of the cross beams 2 via a guide device 3 .

A runner plate 15 is slidably mounted or guided in the respective transverse guide 4 . In the present example, the runner plate 15 is guided in the transverse guide 4 via a running device 19, in particular via rollers.

FIG. 3 shows that the guide device 3 also has a guide rail 13 which is accommodated at least in sections in a guide bushing 14 of the longitudinal beam 1. The guide bar 13 is connected to the runner plate 15 so that it cannot move or rotate. The guide rail 13 is connected to the runner plate 15 and the runner device 19 via a threaded bolt 50 . Furthermore, the threaded bolt 50 is accommodated in the guide rail 13, namely in a threaded opening 51. The guide device 3 thus provides a connection between the longitudinal member 1 and the running device 19 guided in the transverse guide 4 of the respective cross member 2, which allows a relative displacement of the longitudinal member 1 in relation to the Cross member 2 basically allows.

The threaded bolt 50 and the threaded opening 51 provided on the guide rail 13 extend parallel to the longitudinal member 1. The runner plate 15 is clamped between an end of the guide rail 13 facing the cross member 2 and a threaded bolt head 52. Furthermore, a connection element 53 for fastening the running device 19 is provided on the threaded bolt head 52 . As the figures also show, the door system also includes a locking disk 5, which is pivotably mounted on the respective guide device 3, wherein the locking disk 5 when unlocking the locking device using a drive device 6 operatively connected to the locking disk 5 and performing an unlocking pivoting movement of a first end position 11 (see Fig. 5) to a second end position 12 (see Fig. 8) is pivotable. The drive device 6 comprises a drive element 18 provided with a toothing 17 , the toothing 17 engaging in a toothing 16 of the locking disk 5 . The drive device 6 is connected to a drive unit (not shown) via a linkage. The locking disk 5 and the drive element 18 are rotatably mounted on mutually parallel axes of rotation D1, D2 (cf., for example, FIG. 5).

It is characteristic of the present invention that the longitudinal member 1 and the cross member 2 are fixed relative to one another when the unlocking pivoting movement of the locking disk 5 is carried out over a predetermined idling angular amount L of the locking disk 5 . In this case, there is no displacement of the runner plate 15 relative to the transverse guide 4 of the cross member 2 (cf. FIGS. 5, 6).

As can be seen in particular from FIGS. 5 to 8, the locking disk 5 has a curved elongated hole opening 8, in which a guide element 9 arranged in a non-displaceable manner on the crossbeam 2 is partially accommodated and guided. The slot opening 8 extends boomerang-shaped from a first slot end 31 to a second slot end 32 over a section of the locking disk 5.

The functioning of the invention in relation to the unlocking process of the door system proposed by the invention is explained below with reference to FIGS. 5 to 8, with FIG. 5 showing a locked position and FIG. 8 showing an open position. In the locking position of a locking device associated with the door system shown in Figure 5, locking disk 5 is in a first end position 11. In the open position of the locking device shown in Figure 8, locking disk 5 is in a second end position 12. In the locking position (FIG. 5), the guide element 9 is positioned in a first end position 21 in the region of a first end 31 of the slot opening 8 . The locking disk 5 can be pivoted via the drive device 6 or the drive element 18 . First of all, the locking disk 5 is pivoted by an idle angular amount L when unlocking (FIGS. 5, 6). The pivoting movement causes the locking disk 5 to be displaced relative to the guide element 9, so that the guide element 9 changes position from the first end position 21 to a latching position 23, with the latching position 23 being a position in the region of the middle of the elongated hole 33 (cf. Fig. 6 ). The idling angle L corresponds to a change in position of the guide element 9 relative to the locking disk 5 from the first end position 21 in the area of the first slot end 31 to the latching position 23 in the area of the slot center 33 (see FIGS. 5 and 6). When the locking disk 5 is pivoted by the idling angle L in the unlocking pivoting direction 7, there is no relative displacement of the runner plate 15 with respect to the cross member 2; The position of the locking disk 5 according to FIG. 6 corresponds to a position similar to a dead center, in which a displacement of the runner plate 15 (and thus of the side member 1) in the transverse direction Y of the vehicle is prevented.

In contrast to this, the locking disk 5 is in the locking position according to FIG. 5 in an over-center position. In relation to a transverse vehicle plane running parallel to the cross member 2 and perpendicular to the longitudinal member 1, the center point of an imaginary circular section, which extends along a slot leg 41 directly adjoining the first slot end 31, coincides with the axis of rotation D1 of the locking disk 5. When the locking disk 5 is pivoted by the idle angle L, the spatial arrangement (or spatial arrangement) of the axis of rotation D2 of the drive element 18, the axis of rotation D1 of the locking disk 5 and an axis of symmetry S of the guide element 9 is constant. This geometric relationship results in the possibility of free rotation of the locking disk 5 over the angle L. If the locking disk 5 is pivoted beyond the idling angle L in the direction of the unlocking pivoting direction 7 during unlocking, the locking disk 5 is displaced relative to the guide element 9 in such a way that the guide element 9 changes position from the latching position 23 (Fig. 6) via an intermediate position 24 in the area of a second slot end 32 (position according to FIG. 7) to a second end position 22 in the area of the slot center 33 (FIG. 8). This also results in a displacement of the runner plate 15 together with the components connected thereto. Correspondingly, the longitudinal member 1 is displaced relative to the stationary cross member 2. The locking process corresponds to a reversal of the sequence of steps illustrated in FIGS.
