    description
    The invention relates to a device for holding a pulling and pushing device of a coupling, in particular of a rail vehicle, according to the preamble of claim 1.
    In particular, in rail vehicles for freight wagons, the pulling and pushing device of a coupling is simply designed, in which a bridging structure is usually included, which is connected at the front with a separate support element hinged to a pull rod and can be attached to the rear in a vehicle recess of the rail vehicle. This bridging structure consists of plate-shaped parts and it is relatively complex when assembling the pulling and pushing device in the vehicle body.
    The invention is based on the object of improving a device for a holder of a pulling and pushing device constructively in such a way that with it the assemblability is facilitated in a cost-effective production.
    This object is achieved according to the invention in that a box-shaped spacer element is provided as a spacer bridge in the device for holding this pulling and pushing device, which is made in one piece cast together with the support element bearing the pull rod.
    With this device according to the invention, an optimal assembly or disassembly of the pulling and pushing device can be achieved with the spacer element holding it, and this integrally cast production of the same together with the support element results in a considerable cost reduction of the device. In this way, the required strength values of this spacer element, which is subjected to tension or compression, can easily be met.
    Conveniently, this box-shaped spacer element has a square cross-section and it is preferably made of a nodular cast iron or cast steel together with the support element.
    Towards the front, the spacer element is advantageously at least partially tapered and this hub-shaped support element is provided with a central bore for receiving the tie rod.
    On the basis of exemplary embodiments with reference to the drawing, the invention and other advantages thereof are explained in more detail below. It shows:
    1 shows a longitudinal section of a device according to the invention for holding a pull and push
    device of a coupling in a vehicle recess;
    Figure 2 is a perspective side view of the device of Figure 1; and
    Fig. 3 is an end view of the device from the rear.
    1 and 2 show a device 20 for holding a pulling and pushing device of a coupling, in particular of a rail vehicle. In addition, an articulation device 1 is also provided for aligning a coupling head, a head element or the like.
    This device 20 is very advantageous for freight wagons in which such vehicle recesses 33 of a vehicle body 30 are provided on the outside, in each of which a distance bridging is required.
    For this distance bridging, a spacer element 21 is provided according to the invention, which is connected on its front side to a tie rod 2 hinged support element 4 and can be fastened on its rear side in this vehicle recess 33 of the rail vehicle. The spacer element 21 is in the form of a box and is manufactured in one piece together with the support element 4 which supports the tie rod 2.
    This box-shaped spacer element 21 is very advantageously provided with a square cross-section along its longitudinal extension and is preferably made of a nodular cast iron. It could also be made of a cast steel or the like and its cross section could also be designed differently.
    With this configuration of the spacer element 21 optimal strength values of the same are achieved on train and pressure and it can be dimensioned with relatively thin wall thicknesses, preferably in the range of 5 to 20 millimeters for lengths of up to one meter.
    This support element 4 is provided with a central bore with a spherical swivel joint 5 for receiving the pull rod 2 and is additionally extended by a laterally protruding hub 13 for receiving a connecting arm 6 of the articulation device 1. On the front and back of the support element 4 there are several disk-shaped spring elements 3 placed on top of the tie rod 2 to dampen the tensile and compressive forces generated during operation of the rail vehicle, for example seven at the front and three at the rear or a different number. These spring elements 3 ″ acting on tensile force and a stop 19 attached to the end of the pull rod 2 are arranged inside the spacer element 21. The stop 19 inside the spacer element 21 comprises a nut 19 ″ that can be screwed onto the pull rod 2 with a securing element 29 and a pressure plate 19 '. , by which a compression of the spring elements 3 with a defined pressing force is made possible.
    The spacer element 21 is provided on its rear side with an inlet opening 26 such that the spring elements 3 ″ and the stop 19 can be pushed into it. In addition, the spacer element 21 has at least one, preferably several openings 23 on all four sides, which are dimensioned such that the nut 19 ″ of the stop 19 and the spring elements 3 ″ are accessible for mounting from outside the spacer element 21, and that this nut 19 ″ can also be attached to or detached from the tie rod 2 when the spacer element 21 is installed is.
    Furthermore, the spacer element 21 can be fixed by fastening means in the vehicle body 30, for this purpose between jaws 31,32 arranged on both sides in the latter and clamped wedges 27 are provided at the rear in the vehicle recess 33 of the vehicle body 30. The spacer element 21 is formed on both sides next to the support element 4, each with a stop surface 22 corresponding to the respective jaw 31, 32, which each extend transversely to the longitudinal axis of the pull rod 2 along one side surface.
    There are two wedges 27 held by a connecting part 27 'provided, each of which is in contact with a wedge surface at a protruding web 25 of the spacer element 21. The wedges 27 can be tightened by means of preferably two screws 35. In addition, a guide element 34, arranged in the longitudinal direction of the wedges 27, is guided for their guidance in a transverse axis 24 that is releasably fastened in the spacer element 21.
    With these fastening means, a permanent compressive force can be generated on the spacer element 21 so that it remains jammed even in the event of regularly occurring vibrations. These linear lines of force generated by these fastening means from the respective web 25 through each side wall of the spacer element 21 to the stop surface 22 produce only compressive forces on this in an optimal manner. Of course, these fastening means could also be configured differently as explained above, for example as a screw connection, only by means of a wedge 27 or the like.
    Furthermore, starting from these stop surfaces 22, the spacer element 21 is at least partially tapered towards the front side, for example as shown on both sides.
    To hold the tie rod 2 in this plane and return it to a starting position centered relative to the vehicle, a connecting arm 6 of the articulation device 1 aligned parallel to the tie rod 2 is provided, which has a guide rod 8 and a compression spring 7 surrounding it coaxially. The guide rod 8 is attached at one end to a protruding part 15 of a sleeve body 2 'in the pull rod 2 and at the other end is axially displaceable and pivotable in the laterally protruding hub 13 in the support element 4. The sleeve body 2 'and the pull rod 2 are also secured against rotation by a cylinder pin 18.
    The compression spring 7 is expediently held at both ends by one bearing bushes 9, 10 each centered on the guide rod 8, one bearing bush 9 being supported on the part 15. The other bearing bush 10 is designed as a guide sleeve 10 ′ for the compression spring 7. The compression spring 7 is supported on both sides in such a way that it engages on the one hand via the bearing bush 10 on the support element 4 and on the other hand in this part 15 through the bearing bush 9 on the guide rod 8 and an intermediate ring for generating a supporting compressive force.
    In addition, this compression spring 7 is adjustable by an adjusting means in the axial direction with respect to the support element 4, so that the height of the tie rod can be aligned. This adjustment means is preferably assigned a threaded sleeve 11 on the support element 4, on which the bearing bush 10 and thus the compression spring 7 can be adjusted by screwing. As a result, the pull rod 2 is pivoted up or down on the front side about a swivel joint 5 at the support element 4. In principle, this adjustment means could also be arranged in the bearing bush 9 or configured differently.
    The connecting arm 6 as a spring accumulator enables on the one hand the tie rod 2 in the uncoupled state in an approximately horizontal plane and on the other hand the return of the tie rod 2 in a starting position that is centric relative to the vehicle by coupling the same to the support element 4 in such a way that at Deflections of the tie rod 2 a compressive force is generated on the same, which brings it and the coupling head connected to it back into the centered starting position. The latter takes place automatically because the deflection movement of the pull rod automatically activates the spring force of the connecting arm acting on it.
    In the hub 13 of the support element 4, a multi-part spherical bearing 13 'with a flexible rubber bushing as a swivel joint for the guide rod 8 of the connecting arm 6 is installed. In this way, especially in the coupled state, this guide rod 8, which is fastened opposite in part 15 of holder 2 ', is pivoted about the pivot point formed at bearing 13 when pull rod 2 is deflected around the pivot point formed by swivel joint 5.
    After uncoupling, on the one hand, the spring elements 3, which are compressed with a bias, and, on the other hand, this compression spring 7 of the articulation device 1, cause the pull rod to be aligned horizontally and vertically in the longitudinal direction of the car and not incline slightly obliquely downwards.
    According to FIG. 3, this spacer element 21 is designed to be open at the rear and a protruding web 25 is arranged on the side of this for its attachment. An adjusting means is also provided on the upper side, which serves to enable the alignment of the spacer element 21 to the vehicle to be adjusted. As a variant, this can be implemented by a pin 28 and a screw 28 ′ that can be adjusted in this.
