Definitions
- the invention relates to a centerpiece for switches and crossings comprising a centerpiece tip as well as wing rails and running rails running on both sides thereof, each with a basic course aligned with a trunk or siding.
- wheel handlebars perform management tasks, since a wheel flange in the area of a centerpiece gap which is inevitably caused by crossing ruts can no longer guide the wheel on a rail head.
- the axle i.e. the wheel set of a vehicle
- This deflection occurs on trains that have a focal area at a speed of z. B. drive through 160 km / h, in hundreds of seconds.
- these impacts reduce driving comfort and, on the other hand, cause undesirable wear.
- frog tips are extremely narrow in their front area so that they are exposed to increased wear when they are hit by a wheel. This applies to an increased extent if the wheel flange of a wheel in the front area of the frog tip grinds along it.
- EP 0 282 796 B1 there is a targeted expansion of the transition area between the wing rail and frog tip in order to avoid a point-like or sudden force transmission from the wing rail to the frog tip in a very narrow area .
- control arm and the centerpiece as a unit start from a common base, which are supported transversely elastically with respect to a threshold by means of an intermediate layer having spring properties. On the one hand, this protects the tip of the frog and, on the other hand, a sudden interaction between the wheel and the wheel handlebar is avoided.
- Movable frog tips are also known, which is also intended to try to prevent abrupt starting of the frog tip or grinding of the flange along the frog tip.
- the present invention is based on the problem of developing a centerpiece of the type mentioned at the outset in such a way that wear reduction of the centerpiece tip region takes place without the need for redesigning the centerpiece tip itself or the wheel links assigned to it or their alignment with one another.
- the problem is essentially solved in that at least one of the travel rails, in particular both travel rails, deviates from their basic course in the area of the frog tip in such a way that a rail vehicle passing through the trunk or siding has an influence of movement directed away from the frog tip with its wheel or bogie axis experiences.
- the wheel rolling on the rail side undergoes a change in its wheel contact point in such a way that the wheel or bogie axis is forced into alignment with the main or side track in such a way that its normal runs parallel or almost parallel to the respective longitudinal axis of the track to be traversed, with the result that the otherwise sliding or sliding movement of the wheel rim along the flank of the frog tip is prevented.
- the course change of the running rail is designed such that a wheel passing through the running rail is supported on a running circle of a radius r, which is smaller than a running circle r- of the wheel rolling on the frog tip in its support.
- the radii r, to r 2 behave roughly like r,: r 2 «0.91: 1 to r,: r : ⁇ 0.98: 1.
- the running rail in the area of the centerpiece tip is curved in a direction away from the centerpiece tip with respect to its contact line formed by the respective wheel contact points of the wheel, that is, it shows a concave course with respect to the centerpiece tip.
- the line of contact deviating from the basic course between the wheel and the rail head can be achieved in that the head of the rail or its driving surface in the area of the frog tip is more inclined in comparison with the running rail in the basic course towards the frog tip.
- the running rail or its driving surface in the area of the frog tip can be inclined more by an angle ⁇ to the frog tip than the running rail in the basic course, 1.5 ° ⁇ ⁇ 5 °, in particular ⁇ «3 °.
- Optimal protection of the frog tip is achieved when the change in the direction of the travel rail begins at a distance x with 15000 - 20000 mm>x> 5000 mm in front of the frog tip.
- the change in course should end at a distance y of 18000 - 23000 mm>y> 8000 mm behind the start of the frog tip.
- the start and end of the main and branch tracks can vary in distance, but they can also be the same. This essentially depends on the radius of a switch.
- the invention is characterized in that the maximum change in the basic course of the running rail transverse to the main or secondary track is 5 mm to 30 mm. Due to the related widening of the track, the wheel or bogie axis can be influenced in a structurally simple way in such a way that the wheel rolling on the frog tip side cannot approach the frog tip laterally without the required guidance itself being impaired.
- FIG. 1 is a schematic diagram of a frog area with a rigid frog tip
- FIG. 2 shows a schematic diagram of a frog area with a movable frog tip
- FIG. 3 shows a basic illustration of a first embodiment for achieving a change in the course of a running rail
- FIG. 4 shows a basic illustration of a second embodiment in order to achieve a change in the running direction of a rail
- Fig. 5 is a schematic diagram of a third embodiment to achieve a
- Fig. 6 shows a schematic diagram of a travel rail in the area of a frog tip in plan view.
- FIG. 1 and 2 schematically show a frog area 10 or 12, which according to FIG. 1 comprises a rigid frog tip 14 and wing rails 16, 18 running on both sides thereof and travel rails 20, 22.
- wing rails 16, 18 and travel rails 20, 22 are also assigned to a movable centerpiece tip 24 in FIG. 2.
- the main track is identified by reference number 26 and the siding by reference number 28.
- the travel rail 20 of the main track 26 or the travel rail 22 of the secondary track 28 undergoes a change in course such that the wheel of the rail vehicle rolling on the travel rail 20, 22 is influenced in its wheel contact point in such a way that the corresponding axis of the Wheel is aligned with its normal to the main or secondary track 26, 28 in such a way that it runs essentially parallel to its longitudinal axis, so that the wheel rolling on the frog tip 14, 24 does not drag along its flank with its wheel rim.
- the respective change in the course of the travel rails 20, 22 is in principle drawn with the reference symbols 34, 36, whereas the basic curve has the reference symbols 38, 40 in a broken line.
- the change in course 34, 36 can be implemented in various ways, the crucial factor being that in the area of the change in course the wheel contact point shifts away from the frog tip 14, 24.
- the solid line 34, 36 in the actual sense represents the course of contact lines between the wheel and the rail head, i. H. their driving surface.
- the course change 34, 36 is preferably brought about by the fact that the running rail 20, 22 in the area of the frog 14, 24 is curved away from it, that is to say with respect to its running surface on which the respective wheel is supported , shows a course concave to the frog tip 14, 24.
- a wheel 42 is shown in FIG. 3 that rolls on the running rail 20.
- a cross section of the travel rail 20 is shown in the region of the change in course, that is to say in the region 34.
- dashed lines and with reference numeral 44 the rail 20 is identified with its head 44 outside the change in course, that is to say drawn in in the basic course 38.
- the course change which is achieved by the exemplary embodiment in FIG.
- the wheel contact point of the wheel 42 is specifically changed such that the wheel axis and thus the wheel rolling on the centerpiece 14, 24 is "pulled” in the direction of the travel rail 20, thereby ensuring that the wheel flange of the on the frog 14, 24 rolling wheel does not drag along the frog tip 14, 24.
- the wheel or bogie axis is aligned with the main or secondary track 26, 28 or its longitudinal axis in such a way that they essentially describe a right angle to one another with the result that the undesired and premature wear of the Centerpiece tip 14, 24 leading grinding movement of the wheel flange of the wheel rolling on the centerpiece tip 14, 24 along its flank does not occur.
- a course change can also be achieved according to FIG. 4 in that the running rail 20, 22 in the area of the course change 34, 36 runs more inclined in its running surface 46 by machining the head 44 to the frog tip 14, 24 than in the basic course (reference numeral 48) , which in turn results in a change of the wheel contact point of the wheel 42 to the extent that the wheel contact point moves to the outside, ie away from the frog tip 14, 24.
- the driving surface of the head 44 in the area of the course change 34, 36 describes an angle ⁇ with the driving surface in the basic course 38, 40 with 1.5 ° ⁇ ⁇ 5 °.
- the travel rail 20, 22 can be inclined as a whole in the region of the change in course, as is illustrated in FIG. 5.
- the head 44 of the rail is not changed. Rather, its foot 50 z. B. arranged on a wedge plate, not shown, to adjust the required inclination of the running surface of the rail head 44 to influence the wheel contact point.
- the course change of the running rail 20 of the main track 26 should be in front of the frog point 30, 32 at a distance X h with 5000 mm ⁇ X h ⁇ 15000 mm and behind the frog point 30, 32 at a distance Y h with 8000 mm ⁇ Y h ⁇ 18000 mm.
- the change of shape 40 in the side track 28 should the distance X n before the cross frog tip 30, 32 of 5000 mm ⁇ X n ⁇ 20000 mm or be behind the cross frog tip 30, 32 end at a distance Y n of 8000 mm ⁇ Y n ⁇ 23000 mm.
- the maximum deviation Z h or Z n of the wheel contact point in the area of the course change 34 or 36 in comparison to the basic course 38, 40 should be: 5 mm ⁇ Z h ⁇ 30 mm or 5 mm ⁇ Z n ⁇ 35 mm.
- the maximum course change 34 or 36 should run at a distance A n or A h behind the frog tip 30, 32, 300 mm ⁇ A n ⁇ 2000 mm or 300 mm ⁇ A h ⁇ 2000 mm.
- the running rail 20, 22 has a bulge of a corresponding size Z n or Z h .
- a section of the travel rail 20 is again shown in principle in plan view, a dashed line showing a contact line 52 resulting from the contact points between the travel surface of the rail head 44 and the wheel contact point of the wheel 42, which is in the area of the frog tip 30 , 32 curved outwards, that is to say concave with respect to the frog tip 14, 24.
