Description

CONNECTING ARRANGEMENT

FIELD OF THE INVENTION The present invention relates to a connection arrangement for forming a walkable connection between two articulated vehicle parts, in particular a rail vehicle, comprising a base plate and a turntable, the base plate being immovable with respect to a virtual first axis of rotation which is normal to a base plate top side is arranged on a first vehicle part, the turntable being arranged on a second vehicle part and between the base plate and the second vehicle part, the arrangement of the turntable on the second vehicle part being movable with respect to a second axis of rotation which is normal to an upper side of the turntable, the turntable being movable is arranged to the base plate, wherein the base plate has a first contour section and the turntable a second contour section and wherein the first contour section and the second contour section at least in sections are arranged facing each other.

PRIOR ART [0002] Connection arrangements for forming a walk-in connection between two articulated vehicle parts, in particular a rail vehicle, are known from the prior art. allow an offset movement of the two vehicle parts to each other. A disadvantage of known solutions is their large overall length, which in principle goes hand in hand with a correspondingly high space requirement and with resulting additional costs, for example for a necessary bellows, which is arranged in the region of the connection arrangement and must be designed to be correspondingly large.

In connection with attempts to realize more compact connection arrangements, a connection arrangement is known from EP 3225433 B1, which comprises a first turntable and a second turntable. The first turntable has a first circular arc section and is immovably arranged on a first vehicle part. The second turntable is movably arranged between the first circular arc section and a second vehicle part and has an inner contour section in which the first circular arc section sits, so that the second turntable can be guided around the first circular arc section. A drawbar is arranged below the first turntable on the first vehicle part, the drawbar being pivotable at a pivot point and the pivot point coinciding with a center point of the first circular arc section. Below the second turntable, the drawbar is rotatably coupled to the second vehicle part at a connection point, the connection point forming the center of rotation of the second turntable and lying on the first circular arc section. I.e. the radius of the first circular arc section essentially corresponds to the length of the drawbar, so that the size of the first turntable is determined by the length of the drawbar. Accordingly, this connection arrangement also has a considerable overall length.

OBJECT OF THE INVENTION It is therefore an object of the present invention to provide a connection arrangement which allows a further, significant reduction in the overall length.

PRESENTATION OF THE INVENTION To achieve the stated object, it is in a connection arrangement for forming a walkable connection between two articulated vehicle parts, in particular a rail vehicle, comprising a base plate and a turntable, the base plate being normal to a base plate top side / 14

AT 16 674 U1 2020-04-15 Austrian patent office virtual first axis of rotation is immovably arranged on a first vehicle part, the turntable being arranged on a second vehicle part and between the base plate and the second vehicle part, the arrangement of the turntable on the second vehicle part being movable with respect to a second axis of rotation standing normally on a top of the turntable, the turntable being arranged movably to the base plate, the base plate having a first contour section and the turntable having a second contour section and the first contour section and the second contour section being arranged at least in sections pointing towards one another, according to the invention It is provided that the mutually facing sections of the first contour section and the second contour section each comprise at least one section, which section is a straight line as seen along the virtual first axis of rotation or second axis of rotation has some contour.

Since there is no rotation of the base plate about the virtual first axis of rotation relative to the first vehicle part, this axis of rotation is referred to as "virtual". By stipulating that no rotation of the base plate about the virtual first axis of rotation relative to the first vehicle part is provided, it is expressed that other rotations or pivotings of the base plate relative to the first vehicle part are not explicitly excluded, for example pivoting about a pivot axis that stands normally on the virtual first axis of rotation and on a longitudinal axis of the first vehicle part.

Since the turntable is arranged to be movable relative to the base plate, the base plate is of course also arranged to be movable relative to the turntable.

Furthermore, the movable arrangement of the turntable on the second vehicle part based on the second axis of rotation means that the turntable and the second vehicle part can be rotated relative to each other about the second axis of rotation and it is only a question of the relative rotation.

“Straight line contour” means that the contour is essentially or at least approximately straight or that the course of the contour follows a straight line. I.e. a contour with one or more slight deviations from a straight line, for example due to imperfections due to production, is also to be understood as a “linear contour” in the sense of the present invention.

Said sections with a rectilinear contour enable a significantly reduced overall length of the connection arrangement according to the invention compared to known solutions, in particular since the first contour section of the base plate does not have to follow any circular arc shape - with a correspondingly large radius - or no circular arc section - with a correspondingly large radius - represents. In particular, the size of the base plate is practically independent of the length of a drawbar, by means of which the first vehicle part and the second vehicle part can be connected to one another in a manner known per se.

[0011] Likewise, the second contour section does not have to have an arc shape. In particular, the first and / or second contour section can have a sequence of partial sections with a rectilinear contour, which are arranged at an angle to one another in such a way that both rotations and displacements of the turntable and the base plate relative to one another to a sufficiently large extent - as is the case in the operation of the two Vehicle parts typically occur - are possible. Touching the sections of the two contour sections limits the possible rotation or displacement.

This makes it possible for the two vehicle parts which are connected to one another in an articulated manner to be arranged with respect to one another in such a way that they both have an angle to one another and can also be offset from one another. In the case of an angular arrangement, the longitudinal axes of the first and second vehicle parts are not parallel to one another, but instead form an angle not equal to 0 ° with one another. In the case of pure displacement, the longitudinal axes of the two vehicle parts run parallel to one another and are at a distance from one another. Of course, mixed states are possible in practice, in which the first vehicle part and the second vehicle part are angled and offset

It should be noted that the above sequence of sections can of course also be carried out symmetrically. In particular, the sequence of partial sections of the second contour section can be symmetrical to a longitudinal axis of the turntable and / or to a plane in which the longitudinal axis of the turntable runs and which is normal to the top of the turntable. Likewise, the sequence of sections of the first contour section can be symmetrical to the longitudinal axis of the first vehicle part or the base plate and / or to a plane in which the longitudinal axis of the first vehicle part or the base plate extends and which is normal to the base plate top.

The mutually facing sections of the first and second contour section are considered as such if they face each other - at least in a specific arrangement of the base plate and the turntable - for example if the longitudinal axes of the first and second vehicle parts lie one above the other. I.e. it is not excluded that with a different arrangement of the base plate and the turntable - for example if the longitudinal axes of the first and second vehicle parts are not superimposed, but enclose an angle unequal to 0 ° - all the sections pointing towards each other no longer actually point to each other.

The mutually facing sections of the first contour section and second contour section can of course also additionally each have at least one partial section which, seen along the first or second axis of rotation, has a curved, in particular circular, contour. However, this is not necessary. Accordingly, it is provided in a preferred embodiment of the connection arrangement according to the invention that the mutually facing sections of the first contour section and second contour section each consist of at least one section, which section has a rectilinear contour as seen along the virtual first axis of rotation or second axis of rotation.

In a preferred embodiment of the connection arrangement according to the invention it is provided that the at least one partial section is designed to be flat. This ensures a particularly simple and inexpensive producibility. In particular, the at least one partial section of the first contour section can be rectilinear in a sectional plane in which the longitudinal axis of the first vehicle part runs and which is normal to the upper side of the base plate. Analogously, in particular the at least one section of the second contour section can be straight in a sectional plane in which the longitudinal axis of the turntable runs and which is normal to the top of the turntable. However, it would of course also be conceivable that the surface of the partial sections is curved at least in sections and only the respective contour is straight as seen along the first or second axis of rotation. Furthermore, a kind of groove could also be provided in the sections, which leaves the contours of the sections untouched.

In a preferred embodiment of the connection arrangement according to the invention it is provided that the base plate has a guide, the first contour section being arranged in the guide, and wherein the turntable with the second contour section is seated at least in sections in the guide. The guidance in particular limits or prevents movement of the base plate and the turntable relative to one another parallel to the first or second axis of rotation. The guide can be made in one piece with the remaining base plate, or the base plate can be constructed from several parts, the guide being constructed from at least one of these parts. For example, the guide can have an upper guide part and a lower guide part, between which the first contour section and, at least in sections, the turntable with the second contour section are arranged.

In a preferred embodiment of the connection arrangement according to the invention it is provided that a cover plate is provided which covers the first contour section and the second contour section at least in sections, being seen along the virtual first axis of rotation or the second axis of rotation both contour sections behind the

Cover plate are arranged. The cover plate thus enables the connection arrangement to be safely walked on by a user without the user or foreign parts being able to get into the guide or between the base plate and the turntable. At the same time, the cover plate protects the guide or the contour sections from contamination, which has a positive effect on the service life, the functionality and the maintenance expenditure of the connection arrangement according to the invention.

In order to further optimize operational safety and the protection of the guidance of the contour sections mentioned, it is provided in a particularly preferred embodiment of the connection arrangement according to the invention that the cover plate completely covers the first contour section.

In addition, the cover plate can protrude beyond the guide to cover a part of the turntable that is not seated in the guide, thus enabling the user to make the transition as seamless as possible.

In a preferred embodiment of the connection arrangement according to the invention it is provided that at least one first sliding element is provided which is connected to the first vehicle part and on which the turntable is slidably arranged. The at least one first sliding element supports the turntable on the first vehicle part against forces which act on the upper side of the turntable and enclose a non-zero angle with the upper side of the turntable, for example when a user steps on the turntable. At the same time, the at least one first sliding element ensures that said support does not result in any restriction of the mobility of the turntable. If there are displacements and / or rotations of the turntable relative to the base plate, which is the case, for example, when the first and second vehicle parts are displaced relative to one another, the turntable can slide freely on the at least one first sliding element.

In a preferred embodiment of the connection arrangement according to the invention it is provided that at least one second sliding element is provided, which is connected to the second vehicle part and on which the turntable is slidably arranged. The at least one second sliding element supports the turntable on the second vehicle part against forces which act on the top of the turntable and enclose a non-zero angle with the top of the turntable, for example when a user steps on the turntable. At the same time, the at least one second sliding element ensures that said support does not result in any restriction of the mobility of the turntable. If there is relative rotation of the turntable and the second vehicle part relative to one another, which is the case, for example, in the case of an angular arrangement of the first and second vehicle parts relative to one another, the turntable can slide freely on the at least one second sliding element.

In order to be able to reliably guide the relative rotation of the turntable and the second vehicle part to one another, in a preferred embodiment of the connection arrangement according to the invention it is provided that the turntable has a circular arc section, the second vehicle part having an arcuate receptacle in which the circular arc section is received . When the turntable and the second vehicle part rotate relative to one another about the second axis of rotation, the circular arc section of the turntable is thus guided in the circular arc receptacle of the second vehicle part. The second axis of rotation preferably forms the center point for the circular arc section.

In a particularly preferred embodiment of the connection arrangement according to the invention it is provided that a further cover plate is provided which completely covers the circular arc holder. The additional cover plate thus enables the user to safely walk on the connection arrangement without the user or foreign parts being able to get into the circular arc receptacle or between the turntable and the second vehicle part. At the same time, the additional cover plate protects the circular arc holder and at least in sections of the circular arc section from dirt

tion realized, which has a positive effect on the life, functionality and maintenance of the connection arrangement according to the invention.

The additional cover plate can be made in one piece with the circular arc receptacle to enable a particularly stable arrangement.

BRIEF DESCRIPTION OF THE FIGURES The invention will now be explained in more detail using an exemplary embodiment. The drawings are exemplary and are intended to illustrate the inventive concept, but in no way to narrow it down or even reproduce it conclusively.

[0027] Here shows:

Figure 1 a schematic representation of a connection arrangement according to the invention in supervision from above Figure 2 a schematic representation of the connection arrangement of FIG. 1 in supervision from below Figure 3 a schematic representation analogous to FIG. 1, wherein a cover plate and a guide of the connection arrangement are hidden for reasons of clarity Fig. 4 a sectional view taken along section line IV-IV in Fig. 1, the arrows indicate the viewing direction Fig. 5 a schematic representation analogous to FIG. 1, wherein a first vehicle part and a second vehicle part have an angle to each other Figure 6 a schematic representation analogous to FIG. 1, wherein the first vehicle part and the second vehicle part are offset from one another

WAYS OF IMPLEMENTING THE INVENTION FIG. 1 shows a schematic illustration of a connection arrangement 1 according to the invention for forming a walk-in connection between two vehicle parts which are connected to one another in an articulated manner, in particular a rail vehicle. The connection arrangement 1 comprises a base plate 4 and a turntable 5, the base plate 4 being arranged immovably on a first vehicle part 2 in relation to a virtual first axis of rotation 8 standing normally on a base plate top side 6. The virtual first axis of rotation 8 could be referred to as “virtual” insofar as there is actually no rotation of the base plate 4 about the virtual first axis of rotation 8 relative to the first vehicle part 2.

The turntable 5 is arranged on a second vehicle part 3 and between the base plate 4 and the second vehicle part 3. The arrangement of the turntable 5 on the second vehicle part 3 is movable with respect to a second axis of rotation 9 which is normal to an upper side 7 of the turntable, i.e. the turntable 5 and the second vehicle part 3 can be rotated relative to one another about the second axis of rotation 9, with only the relative rotation being important. The turntable 5 has an arc section 18 and the second vehicle part 3 has an arc receptacle 19 in which the arc section 18 is received such that the turntable 5 can be rotated with the arc section 18 in the arc receptacle 19. The second axis of rotation 9 forms the center point for the circular arc section 18.

Furthermore, the turntable 5 is arranged to be movable relative to the base plate 4, whereby the base plate 4 is of course also arranged to be movable relative to the turntable 5.

The base plate 4 has a first contour section 10 and the turntable 5 has a second contour section 11, the first contour section 10 and the second contour section 11 being arranged at least in sections pointing towards one another. According to the invention, it is provided that the mutually facing sections of the first contour section 10 and the second contour section 11 each comprise at least one partial section which runs along the

5/14

AT 16 674 U1 2020-04-15 Austrian patent office seen virtual first axis of rotation 8 or second axis of rotation 9 has a rectilinear contour.

The contour sections 10, 11 designed in this way ensure, with a minimal overall length of the connection arrangement 1, that the base plate 4 and the turntable 5 to a certain extent - as is typically the case in the operation of the two vehicle parts 2, 3, both rotatable and displaceable relative to one another are. This makes it possible for the two vehicle parts 2, 3, which are connected to one another in an articulated manner, to be arranged with respect to one another in such a way that they both have an angle to one another and can also be offset from one another. In the case of an angular arrangement, a longitudinal axis 29 of the first vehicle part 2 and a longitudinal axis 21 of the second vehicle part 3 are not parallel to one another, but instead form an angle other than 0 °, cf. 5. In the case of a pure displacement, the longitudinal axes 29, 21 of the two vehicle parts 2, 3 run parallel to one another and are at a distance from one another, cf. Fig. 6. Of course, mixed states are possible in practice, in which the first vehicle part 2 and the second vehicle part 3 are arranged at an angle and offset to one another.

In the exemplary embodiment shown, that section of the first contour section 10 which faces the turntable 5 or the second contour section 11 consists of a single flat section 12. That section of the second contour section 11 which faces the base plate 4 or the first contour section 10 has, in the exemplary embodiment shown, a total of six flat sections 13. When viewed in the direction of the virtual first axis of rotation 8 and / or the second axis of rotation 9, all sections 12, 13 each have a rectilinear contour, which can be seen particularly well in FIG. 3 , in which figure a cover plate 15 and a guide 14 are hidden for reasons of clarity.

In the exemplary embodiment shown, the sequence of the subsections 13 is as follows, reference being made to FIG. 3, in which the subsections 13 are provided with reference numerals 13a, 13b, 13c, 13d, 13e, 13f for easier assignment: From An edge 31 of the turntable 5 initially extends a relatively short section 13a, the contour of which extends approximately perpendicular, in particular in the range 75 ° to 105 °, to a longitudinal axis 30 of the turntable 5. The contour of the adjoining section 13b encloses an obtuse angle with the contour of the section 13a such that the course of the section 13b or the contour of the section 13b points from the section 13a to the longitudinal axis 30 and the circular arc section 18. The section 13b or its contour is significantly longer than the section 13a or its contour, typically by a factor of 3 to 5. The section 13b is followed by the section 13c, the contour of which also forms an obtuse angle with the contour of the section 13b in such a way that the course of the section 13c or the contour of the section 13c points from the section 13b to the longitudinal axis 30 and away from the circular arc section 18. The section 13c or its contour extends up to the longitudinal axis 30 and is significantly longer than the section 13b or its contour, typically by at least a factor 2. The remaining sections 13 are related to the longitudinal axis 30 or to a plane which is spanned by the longitudinal axis 30 and the second axis of rotation 9, arranged symmetrically. The section 13d is symmetrical to section 13c, the section 13e is symmetrical to section 13b and the section 13f is symmetrical to section 13a.

The articulated connection of the two vehicle parts 2, 3 is realized in the illustrated embodiment by means of a drawbar 25 which runs or is arranged under the base plate 4 and the turntable 5, cf. Fig. 2. One end of the drawbar 25 is rotatably connected to the first vehicle part 2 at a pivot point 22. Furthermore, the drawbar 25 is rotatably connected at its other end by means of a connecting element 27 to a coupling element 26 about the second axis of rotation 9, the coupling element 26 being rigidly connected to the second vehicle part 3. I.e. the drawbar 5 is thus also rotatably connected to the second vehicle part 3. The coupling element 26 can, for example, have an eye and the other end of the drawbar 25 has an eye fork, the connecting element 27 being designed as a bolt which is received in the eye and in the eye fork in order to make the connection

4th

With an angular arrangement of the two vehicle parts 2, 3 to each other, there is above all a rotation between the second vehicle part 3 and the drawbar 25 about the second axis of rotation 9, so that the longitudinal axis 21 of the second vehicle part 3 is no longer parallel to one Longitudinal axis 28 of the drawbar, cf. 5. The longitudinal axis 28 of the drawbar 25 can, however, be parallel to the longitudinal axis 29 of the first vehicle part 2.

When the two vehicle parts 2, 3 are offset from one another, there is also a rotation of the drawbar 25 about the pivot point 22, so that the longitudinal axis 28 no longer runs parallel to the longitudinal axis 29 of the first vehicle part 2, cf. Fig. 6.

In particular, to largely prevent movement of the base plate 4 and the turntable 5 relative to one another parallel to the virtual first axis of rotation 8 or to the second axis of rotation 9, the base plate 4 has the guide 14. The first contour section 10 is arranged in the guide 14, and the turntable 5 is seated in the guide 14 with the second contour section 11 at least in sections, depending on the arrangement of base plate 4 and turntable 5 relative to one another. In the exemplary embodiment shown, the base plate 4 is constructed from several parts, the guide 14 having an upper guide part 23 and a lower guide part 24, between which the first contour section 10 and, at least in sections, the turntable 5 with the second contour section 11 are arranged, cf. Fig. 4.

The cover plate 15 completely covers the upper guide part 23 and the first contour section 10, cf. Fig. 1, and thus enables a safe walk on the connection arrangement 1 by a user. In this context, it should be emphasized that the sectional view of FIG. 4 is only a schematic illustration and the distance between the cover plate 15 and the base plate 4 or the turntable 5 is actually so small that the user stumbles practically is excluded.

Analogously, a further cover plate 20 is provided which completely covers the circular arc receptacle 19, cf. Fig. 1. This further cover plate 20 is formed in one piece with the circular arc holder 19 in the illustrated embodiment, cf. Fig. 4.

To support the turntable 5 on the first vehicle part 2, two first sliding elements 16 are provided which are rigidly connected to the first vehicle part 2 and on which the turntable 5 is slidably arranged. In the exemplary embodiment shown, the first sliding elements 16 are designed as blocks with a rectangular or square base area.

Analogously, a second sliding element 17 is provided for supporting the turntable 5 on the second vehicle part 3, which is rigidly connected to the second vehicle part 3 and on which the turntable 5 is also slidably arranged. In the exemplary embodiment shown, the second sliding element 17 has an arc-shaped base area.

The first sliding elements 16 and the second sliding element 17 are preferably made of plastic, for example made of polyamide-6 (polycaprolactam).
