Definitions
- the present invention relates to a train coupling with a coupling rod and a pressure plate, which together limit a coupling play, in detail according to the preamble of claim 1.
- the invention further relates to a rail vehicle with at least two adjacent and mutually coupled or coupled carriages, each of which have such a pulling coupling for coupling.
- the coupling play in particular the coupling joint play, is, however, disadvantageous with regard to load change reactions from the driving dynamics and is shown by jerking movements that are clearly perceptible in the traction vehicle.
- the conventional, comparatively large coupling play leads to comparatively higher load change forces when the individual rail cars are driven on and pulled, which requires a higher fatigue strength of the coupling components.
- Couplings with coupling heads of type 10 (Scharfenberg coupling - version with a funnel and a cone, which are arranged on a face plate), as it relates to the present invention in particular, are used in the freight sector, for example in combined transport, i.e. in freight wagons that are used as container wagons or pocket wagons are designed for the transport of trucks and / or trailers.
- the train mass of such freight wagons is significantly lower than that of freight wagons that are used to transport bulk goods or steel.
- the present invention is based on the object of specifying a train coupling which is less stressed when used, in particular in freight wagons, so that the service life is extended and / or the requirements for fatigue strength can be reduced.
- train sets When used in train sets, the load change forces when driving up and pulling on the individual rail carriages are to be reduced and the vibration behavior as a whole has to be improved.
- the present invention is based on the knowledge that the conventional pronounced coupling play for starting the train, in order to attract the train wagon by car, is often no longer necessary and the higher tractive effort of modern railcars can be used to reduce the coupling play in favor of better dynamic properties in freight transport . Therefore, the joint play of the train coupling is preferably reduced while maintaining the existing contours, in particular while maintaining the horizontally and vertically acting stabilization, which interacts with the coupling deflection the pressure plate of the spring mechanism and the stroke-dependent pressure force development causes a transverse force reduction through a restoring torque.
- a train coupling according to the invention has a coupling rod which extends in the direction of a longitudinal axis, i.e. in the longitudinal direction or in the direction of travel of the rail vehicle provided with the train coupling, the longitudinal axis and the direction of travel at least in the non-deflected state of the coupling rod, i.e. in its central position, coincide.
- the coupling rod carries a coupling device for an opposing train coupling and at a second axial end opposite the first axial end in the direction of the longitudinal axis, the coupling rod is rotatably mounted about an axis of rotation, for example on the car body of a rail vehicle or on the frame of a rail vehicle.
- the coupling rod is also displaceable in the direction of the longitudinal axis, for example in relation to a pivot pin which the coupling rod encloses with an opening.
- the tension coupling also has a pressure plate which faces the front stop surface in the direction of the longitudinal axis, the pressure plate comprising a surface facing the front stop surface.
- the pressure plate is, for example, rigid or resilient in the rail vehicle which carries a train coupling according to the invention, or is mounted in the train coupling.
- the end stop surface has been mechanically processed in the casting process after its production.
- the surface of the pressure plate can accordingly also be mechanically processed after the production of the pressure plate in the casting process and / or by forging.
- the mechanical processing preferably of the end stop surface, enables a contour adaptation of the coupling joint and thus a targeted adjustment of the maximum coupling joint play.
- the coupling joint play is adjusted by the mechanical processing as a function of the intended use of the coupling.
- the mechanical processing allows the coupling joint play to be increased at any time when the coupling rod has been manufactured and possibly even has already been used in a pulling coupling.
- the surface of the pressure plate is convex, in particular spherical.
- the opening is limited on one side in the direction of the longitudinal axis by a cylinder segment-shaped contour in the coupling rod and on the other side by a stop inserted into the coupling rod.
- the stop can, for example, have a flat or curved, in particular concave, stop surface.
- the minimum wall thickness of the coupling rod between the opening and the end stop surface is preferably at least 20 times, in particular 21 times the maximum coupling joint play.
- the minimum wall thickness is such as this, for example after the coupling rod has been cast chosen that enough material is available for mechanical processing to adjust the joint play specifically through mechanical processing.
- the coupling device at the first axial end of the coupling rod preferably has an end plate with a coupling funnel and a coupling cone and is designed, for example, as a Scharfenberg coupling type 10.
- a rail vehicle with at least two carriages arranged next to one another or one behind the other when viewed in the longitudinal direction of the rail vehicle and which can be coupled to one another and coupled in the coupled state, the two carriages arranged next to one another each having a drawbar coupling according to one of claims 1 to 8 for coupling to one another at their end regions facing one another is described in claim 9.
- the coupling of the individual wagons via train couplings designed according to the invention leads to a reduction in the load change forces when changing traction due to the reduction in the total coupling joint play and thus to an overall improvement in the vibration behavior in the overall structure.
- FIG. 1 A rail vehicle 16, the individual carriages 17.1 to 17.4 of which are coupled by means of train couplings 20 of this type, is described in FIG.
- the coupling rod 1 is rotatably mounted about an axis of rotation 11.
- the coupling rod 1 can thus be deflected relative to a longitudinal direction of the rail vehicle which has the train coupling, for example for cornering of the coupled rail vehicle.
- the non-deflected state of the coupling rod 1, in which the longitudinal axis 10 coincides with a longitudinal axis of the rail vehicle which has the train coupling, is referred to as the middle position.
- the play details mentioned here relate to this middle position, although FIG. 1 shows a deflected position which results when the rail vehicle travels through a right-hand bend.
- the coupling rod 1 is also positioned displaceably in the direction of the longitudinal axis 10.
- the coupling rod 1 has an opening 6 in the area of the axis of rotation 11 which encloses a pivot pin 7.
- the pivot pin 7 is cylindrical, aligned vertically and forms the axis of rotation 11 as its cylinder axis.
- the opening 6 is delimited on the side facing away from the first axial end 1.1 by a cylinder segment-shaped contour 8 and on the opposite axial side by a stop 9 which is inserted into the coupling rod 1.
- the stop 9 has, for example, a flat stop surface 9.1 on which the pivot pin 7 strikes in the maximally retracted state of the coupling rod 1.
- the stop surface 9.1 can, however, also be arranged so far away from the pivot pin 7 or the contour 8 that no stops occur in the normal state of the pulling coupling.
- the pressure plate 4 can, for example, be mounted resiliently in the direction of the longitudinal axis 10 in the train coupling or in a rail vehicle, for example on its car body or in its frame.
- a spring element 15 is provided which dampens pressure forces acting on the pressure plate 4.
- the end stop surface 3 rests at least in a punctiform manner on the surface 5 of the pressure plate 4.
- the maximally extended state of the coupling rod 1 in particular that of the force-free traction position (the drawbar rests on the hinge pin without force), there is a maximum coupling joint play S between the end stop surface 3 and the surface 5 of the pressure plate 4.
- the maximum coupling joint play S relates to the middle area of the end stop surface 3, which is located on the longitudinal axis 10, and corresponds to the maximum coupling joint play S in a non-deflected state of the coupling rod 1, i.e.
- a gap between the end stop surface 3 and the surface 5 of the pressure plate 4 on both sides of the longitudinal axis 10 running through the axis of rotation 11 is in particular symmetrical to the longitudinal axis 10, at least in a plan view in the direction of the axis of rotation 11.
- the coupling joint play S is a maximum of 10% of a minimum distance in the direction of the longitudinal axis 10 between the end stop surface 3 and the axis of rotation 11, preferably in the range of 6% to 8%. In FIG. 1, this distance is denoted by d.
- the minimum wall thickness m of the coupling rod 1 between the opening 6 and the end stop surface 3 is preferably at least 20 times the maximum coupling joint play S.
- 17.3 and 17.3 and 17.4 are each coupled to one another via tension couplings 20 arranged thereon and designed according to the invention.
- the coupled wagons thus form a train set.
- At least one of the carriages 17.1 and / or 17.4 in the end area of the train formation is designed as a self-propelled car, in particular a tractor.
- the carriage 17.1 which pulls the carriages 17.2 to 17.4.
- 17.4 are each equipped with train couplings designed according to the invention, the carriages arranged adjacent to one another being coupled to one another via such train couplings 20.
- the carriages arranged adjacent to one another viewed in the longitudinal direction, have tensile couplings 20 arranged and aligned with one another on the sides facing one another, which can be brought into engagement with one another for coupling and are coupled to one another in the train combination.
- the individual tension couplings 20 have a coupling joint play S which amounts to a maximum of 10% of a minimum distance d in the direction of the longitudinal axis 10 between the end stop surface 3 and the axis of rotation 11 in the maximally extended state of the coupling rod 1.
- the coupling joint play S of a tension coupling is preferably selected in the range from 5 mm to 10 mm inclusive, particularly preferably 5 mm to 7 mm.
