    Description: The invention relates to an articulation device for a clutch according to the preamble of claim 1.
    A linkage device of this type is disclosed in EP 2 322 403 B1, in which the spring elements are rigidly clamped and as a result cannot participate in the steering movements of the pull rod. As a result, the damping effect of the spring elements is impaired because the coupling only stresses them unevenly in the deflected position.
    The invention has for its object to avoid this disadvantage and to provide an articulation device of the type mentioned, which ensures an optimal damping effect of the spring elements with the simplest possible means even when the clutch is deflected.
    This object is achieved in that the pull rod for a deflection is mounted at least in a horizontal plane in a rotatable plate in the housing, which is arranged between the spring elements.
    This ensures that a deflection of the coupling head connected to it is made possible by this device and thereby the pull rod and the. you stored spring elements and this plate also occupy these pivot positions.
    It is particularly advantageous in the sense of a simple construction if the rotatable plate and the steering pin are integrated in an annular disc with two diametrically arranged pivot pins, the annular disc being provided with a central through hole for the pull rod.
    So that the spring elements can also perform a deflection of the coupling in the vertical plane, the invention provides for the through hole to be flared on both sides towards the outside.
    The invention further provides that the spring elements for damping the pressure forces are arranged on the side facing the coupling head of the rotatable plate, while the spring elements for damping the tensile forces are mounted on the side of the rotating plate facing away from the coupling head. As a result, the rotatable plate is effective in both directions of force.
    The pressure forces occurring in the clutch are in practice a multiple of the tensile forces acting on them. The invention therefore also provides for the number of spring elements corresponding to the pressure or pressure to be expected in each case. To determine tensile forces.
    For a damping effect which is as uniform as possible, it is expedient to produce the spring elements as ’ring disks from an elastomeric material, which are supported laterally against intermediate spacing disks made of sheet metal.
    It is also advantageous in the sense of a simple, compact design if the spring elements are mounted on the tie rod between a sleeve arranged on the front tie rod end for the coupling head and a locking disk arranged on the rear tie rod end for fixing the spring elements against the rotatable plate.
    To facilitate assembly, the invention also provides that the locking disc can be pressed against the spring elements with a screw arranged at the rear tie rod end.
    The invention also provides that the steering pin with the rotatable plate is mounted in a sleeve-shaped housing with a flange attachable to the rail vehicle. In this way, the housing with the steering pin, the rotatable plate and the tie rod with the spring elements can be fixed to the rail vehicle as a pre-assembled assembly.
    The linkage device according to the invention can also be provided with an overload protection. In this case, the housing is displaceable in the flange, both parts being fixed against one another in normal operation with at least one preferably bolt-shaped overload element, while in the event of a strong impact, the overload element is sheared off by the housing and this by the flange together with the rotatable plate and the Drawbar with the spring elements is pushed back.
    The housing can also be provided at the end facing away from the coupling head with a safety element attached to the flange in the form of a plastically deformable piece of pipe which, in the event of overload, interacts with a hub of the housing penetrating into the piece of pipe in the event of overload.
    The invention is explained below using exemplary embodiments with reference to the drawing. Show it:
    1 shows a longitudinal section of a linkage device for a coupling of a rail vehicle, the sections not being shown hatched;
    FIG. 2 shows the plate of the articulation device according to FIG. 1 in a front view or the pull rod in cross section; and
    CH 713 677 A2
    3 shows a longitudinal section of a variant of the articulation device according to FIG. 1 with a plastically deformable piece of pipe as a safety element.
    1 is constructed as an independent assembly and it comprises a pull rod 1 with spring elements 2a, 2b mounted on it for damping the compressive and tensile forces acting on the coupling, and a housing 3 with a flange 4, with which the assembly is mounted on the rail vehicle or the like.
    According to the invention, the spring elements 2a, 2b are arranged on both sides of a plate 5 which is rotatable about the axis of rotation 6 of a steering pin 7 for the pull rod 1. 2, the rotatable plate 5 comprises an annular disk 8 and a steering pin 7 with two diametrically arranged pivot pins 9a, 9b, the annular disk 8 being provided with a central through-bore 10 through which the pull rod 1 projects while the pivot pin 9a. 9b are stored in bores in the housing 3. To enable assembly, the housing 3 is formed by two half-shells along the central diametral plane.
    The through hole 10 and the tie rod 1 are advantageously seen in cross section on both sides with a flat 10 'so that the tie rod 1 is secured against rotation. In addition, this through bore 10 is formed, at least in the upper and lower regions in the axial direction, starting from its center on both sides outwards with widenings 10. This also enables the coupling to be deflected in the vertical plane, the bore being designed such that the coupling can deflect up and down in the vertical plane by approximately +/- 6 °.
    The construction is designed for a deflection of the tie rod 1 and thus the coupling head in the horizontal plane of about +/- 20 ° to the right and left.
    The spring elements 2a on the side of the rotatable plate 5 facing the coupling head serve to dampen the compressive forces acting on the coupling. They are made of an elastomeric material, the spring assembly with a max. Pressure stroke of a total of approx. 60 mm. The spring element 2b on the side of the rotatable plate 5 facing away from the coupling head is also made of an elastomeric material and in turn serves to dampen the tensile forces acting on the coupling. These are much smaller than the pressure forces that occur. Accordingly, the spring element 2b with a max. Pull stroke of approx. 10 mm.
    The number of spring elements on the front and rear of the rotatable plate 5 can be determined from case to case, the pressure and tensile forces to be expected during coupling. In the package formed according to FIG. 1, five spring elements 2a or one spring element 2b are provided between the front sleeve and the plate between the plate and a rear locking disk 13.
    When the clutch is deflected, the rotatable plate 5 is also deflected within the above-mentioned limit values. As a result, even when the coupling is deflected, the compressive and tensile forces acting on it act uniformly on the spring element 2a, 2b over their entire surface. As a result, the damping effect of the spring elements is optimal. In this sense, it is advantageous if the spring elements are supported laterally with spacers 11 made of sheet metal lying between them.
    The spring elements 2a, 2b are installed on the tie rod 1 between a sleeve 12 arranged on the front tie rod end, to which the coupling head can be connected, for example by welding, and the locking disk 13 arranged on the rear tie rod end. The latter serves to fix the spring elements 2a, 2b and the rotatable plate 5 against the sleeve 12 by being pressed against a screw connection 14 which can be screwed into the rear tie rod end.
    After the assembly consisting of the housing 3 with the flange 4, the rotatable plate 5 with the steering pin 7 and the tie rod 1 with the spring elements 2a, 2b is mounted on the rail vehicle, the clutch with coupling head and pulling and pushing device are welded to the sleeve 12 of the tie rod 1. The design described is advantageous both for the assembly of the articulation device and for the inspection and adjustability of the individual components.
    The linkage device can also be provided with an overload protection. In this case, the housing 3 is axially displaceable in the flange 4, both parts being fixed against one another in normal operation with bolt-shaped overload elements 15a, 15b which are sheared off by the housing 3 in the event of an overload. As a result, this housing can be pushed through the flange 4 together with the rotatable plate 5 and the pull rod 1 with the spring elements 2a, 2b. The number of overload elements can vary depending on a defined impact force.
    Within the scope of the invention, the articulation device can also include a safety device which absorbs the impact energy within certain limits, for example when another vehicle impacts. Such a device is shown in FIG. 3. At the end facing away from the coupling head, the housing 3 additionally has a safety element attached to the flange 4 in the form of a plastically deformable pipe section 16, which, in the event of overload, interacts with a hub 17 of the housing 3 penetrating into the pipe section 16 in an energy-absorbing manner.
    CH 713 677 A2 The pipe end of the pipe section 16 provided with a diameter widening 16a projects into an annular gap 18 between the flange 4 and the housing 3 and is connected to the flange 4 with a detachable connection, such as preferably a screw or bayonet connection , attached.
    The housing 3 and the flange 4 could also consist of one part if no additional overload elements were provided. The pivotable plate 5 could consist of the washer 8 and the pivots 9a, 9b screwed into it, for example, so that the pull rod with the spring elements and the washer could be inserted into the housing and the pivots could then be screwed into the washer from the outside.
    The through hole 10 in the plate 5 could also be approximately cylindrical without lateral flats 10 '. In addition, seen in the lateral areas in the axial direction, starting from its center, it could also be provided with widenings on both sides outwards.
