Description

BACKGROUND OF THE INVENTION The present invention relates to a changeover device with an internal locking mechanism, a drawbar connected to the shifting rails, a variable pivoting load on a pivoting pivot, which is connected to the actuator by means of a spring loaded with a spring bar.

It is known to have an object-type electro-hydraulic gearbox adjuster, which is used under the designation Deutsche Bundesbahn / German Federal Railways / L 00H and which is described in the "Signal und Draht o. 65 · issue of the Federal Gazette / 1975 · Booklet 4 / page 67 · For a more detailed description of this machine, see 19 52 824.6 ·. s. Published by the German Federal Government. Both references contain references to the use of electro-hydraulic devices for shifting transmissions while considering the mechanical structural problem of transducer cutting. It is known from the above publications that the conversion force is transmitted from the piston of a cylinder of a cylinder to the spring housing which is tightly connected by a draw bar and thus creates a linear conversion movement. The design and operation of the spring housing is described in Signal and Draht. 10 and 12 of the quoted article in the journal are well illustrated and are described in the text.

The requirements for bills of exchange vary greatly from country to country. In the Federal Republic of Germany, cut-backs are used, whereas foreigners do not usually decide 180801.

For reasons of manufacturing and production rationalization, it is desirable to develop gearboxes with internal mounting * which are based on uniform design principles and which can be used for transmissions with or without cutting.

The invention is based on an internal locking gear shifting device which comprises a spring housing as a transmission member. The object of the present invention is to adapt or to adapt to the gearboxes of any design with or without cut-off by the simplest possible structural modification. design of an adjustable gear shifting device.

SUMMARY OF THE INVENTION This object is achieved by providing an object-changeable internal locking gear adjusting device having, in accordance with the present invention, a sliding member * with a hoofscut groove guided between the drawbars and having a hollow pivot for receiving the roller. The cut-out of the drawbar for the respective gap / stand / vertex shall be inclined at its opposite face to the direction of movement of the drawbar when reversing, and the grooves shall have a length at least equal to the length of the oblique face of the drawbar.

The shifter adjusting device of the present invention can be constructed with as little structural modification as possible. non-cut design. On the one hand, this conversion is limited to the choice of the length of the grooves * and, on the other hand, to the formation of an oblique groove on one of the front faces of the cutout in the hollow bar of the corresponding gap.

In the case of non-cut gear shifting adjusting devices according to the invention, it has proved to be advantageous to use a construction in which the end face of the drawbar for the respective gap-resistant hinge is only partially inclined. This, on the one hand, excludes the possibility of a complete cut of the gearbox and, on the other hand, a slight displacement of the apex of the gap when attempting to cut, which allows the recording of such attempted cuts.

It has also been found advantageous to have embodiments of the gear shifting device according to the invention which have an upwardly adjustable lockable, adjustable locking mechanism of the roller named in the spring housing to prevent movement. This allows you to switch between the cutter shifting gear adjusters and the non-cut gear design with a single gesture.

The design of the gear shifting device according to the invention enables the rational production of gearboxes with or without cut-off depending on the particular operating conditions at the time and provides a high degree of flexibility in using virtually all national and international requirements using the same design principle.

The shifting device according to the invention is exemplified below. Embodiments of the invention will be described in detail with reference to the accompanying drawings. In the drawing it is

Figure 5 is a partial sectional sketch showing a sectional view of an exemplary embodiment of the spring housing and the essential structural elements for providing the switchability from a split design to a non-split design.

Fig. 1 is a perspective schematic diagram illustrating the spatial and functional arrangement of the essential structural members of an internal anchor transaxle adjusting device according to the present invention. Between the two drawbars 2 and 2 'for adjusting the gearbox, a slider 7 is arranged. A 4 spring housing, which is only partially indicated / which is shown in Figs. Figures 1 to 5 will further illustrate / surround the slide element 6 and the drawbar 2, 2 *, which is also an attack element of the shifting force. The drawbars 2, 2 * are each provided with guide rails 8, 8 *, which fit into the grooves L, L * of the slide element 7. The spring in the spring housing 4 preloads and clamps the roller 6 into the respective recess of the slide member 7, thereby establishing and maintaining a force-tight connection between the spring housing 4 and the drawbars 2,2 'on the roller 6, slide member 7 and 3.8'. through pins. The shifting end positions are locked by locking bars 9,9 ', not shown in Figure 1. These are coupled to the appropriate cutouts on the 2,2 'drawbars, and the shifting movement can occur only when these 9.9 * locking bars leave the corresponding cutouts.

The shape of the cut-out and the grooves L and L 'of the drawbar 2 (which must be connected to the respective gap at the respective gap) are of particular importance in relation to the shifting cut. Figure 1 illustrates an exemplary cut-away embodiment of a gear shifting device according to the invention, which is recognizable by an oblique cutout of the drawbar 2. When a railway car cuts the shifter, the drawbar 2 first moves backward (in the direction of arrow A) while the locking rod 9 moves (in accordance with arrow B) and the driving pin 8 in the groove L simultaneously moves backward. When the locking rod 9 is fully raised, the driving pin 9 also reaches the end of the groove L and then carries the slide element 7 with it. The spring locking spring on the roller 6 is overcome by the force applied and the roller 6 protrudes from the recess. The slide element 7 then carries the drawbar 2 * with the help of the driving pin 8 *, since it can also move freely due to the release of the locking rod 9. Thus both 2, 2 * are thus. drawbar moves backwards and allows shifting cutting.

In the non-cut design, the cut-out in the drawbar 2 is only partially inclined / see Figures 4a, 4b. and the groove L is as long as the rod length of the inclined portion of the recess.

In the case of an attempt to change a shifting arm, the locking rod 9 is only partially highlighted / can be used to indicate the clipping attempt / If, however, the locking rod 9 reaches the end of the slanting course, the forward pin 8 is not moved backward it is possible that the actuator remains locked with the locking bars 9 and 9 *.

A 2aa - 2cb. Figures 3 to 5 show three snapshots of the conversion process with a schematic sectional and plan view of an exemplary actuator of the present invention.

A 2aa. and 2ab. Fig. 2A shows the position of the structural members before the transfer operation. The locking rod 9 secures the drawbars 2 and 2 * and holds the spring housing 4 firmly by the locking rod 10. The locking rod 9 is displaced by a PV force so that the drawbars 2,2 'are released. The PV force is preferably generated by a hydraulic force.

2ba. and 2bb. Fig. 4A shows the position of the structural members during the conversion operation. The drawbars 2 and 2 'are not fixed and the force exerted on the spring housing 4 displaces the two drawbars 2 and 2' by means of a force-locking connection through the roller 6, the slide element 7 and the driving pins 8.8 '. The converter is preferably a hydraulic force which is created according to the aforementioned article of Signal und Draht, which is not relevant here.

Finally, 2ca. · And 2cb. Fig. 6A shows the end position of the structural members after the gear shifting operation. When the locking rod 10 'passes over the locking rod 9', the force F 'of a pre-tensioned spring acts in the opposite direction on the locking rod 9' and returns it to the locking position of the drawbar 2, 2 * and locking rod 10 'of the spring housing. Activation of the locking rod 9 'operates in a known manner a contact which interrupts the application of the switching force. This completes the migration process.

A Share. - 5cb. Figures 3 to 5 show three snapshots of the trimming process, also in section and top view. A Share. and Jab. Figs. and 2ab. They differ from Figures 1 to 5 only in that, instead of the hydraulic PV force and the shear force, at the beginning of the shear cutting process, a thrust P acts on the drawbar 2, which attempts to push it. 3ba. and 3bb. The position of the structural members is shown after the roller 6 has protruded from the corresponding recess of the slide element 7. The roller 6 can project when the thrust P acting on the drawbar 2 exceeds the value of the x-locking force set during the preparation. In this way, the force locking connection between the spring housing 4 and the drawbars 2,2 'is released.

From the position of the trigger pins 8 and 8 *, it can be seen that the force P carries the drawbar 2 'through the drawbar 2; this is also evident from the changed position of the cutouts on the drawbars 2, 2 '. The spring housing 4 remains in its original position until now. as long as the transmission hydraulics are not detected by the drive hydraulics.

3ca. and Jcb. Fig. 2A shows the end position of the drawbars 2, 2 'after the shift cutting process; for recovery and restoring the original position, the hydraulics are actuated similarly to a normal resetting operation, in which the spring housing 4 moves along the rods 2, 2 *, the roller 6 rises on the slide member 7 and finally snaps into the recess *, 2 'drawbar and 4 spring housing

-4180251 The power connection is restored.

4a. and 4b. Figures 2 to 5 show, in a top view, the cutouts on the drawbar 2.2 * for a non-cut gear shifting device according to the invention.

4a. it shows the locking bar 9 in its locked, locked state when the thrust p attempts to push the drawbar 2. The result is shown in Figure 4b. As shown in FIG. 6A, the locking rod 9 is slightly raised by the oblique section of the cut-out, but it remains stuck in the vertical front face portion of the cut-out. So, first, the shift cutting process 1 begins and the movement of the locking rod 9 indicates the cutting attempt. However, each of the 2, 2 * drawbars will remain fixed to the 5.3 &quot; Figs.

Thus, the shifter adjusting device of the present invention allows only the construction of the cutouts on the drawbars to make the shackle adjuster internally fixed to be cut or not, assuming that the grooves L and L 'correspond to the dimensions of the cutouts.

If the shifter adjusting device according to the invention has a cut-out design, i.e. the drawbar 2 has a completely oblique groove cut-out (see Fig. 1), there is a further possibility that the shifter adjusting device can not be cut-off if necessary.

An exemplary embodiment of the internal locking gear adjusting device of the present invention is shown in Figure 5. By means of an interlocking latch 11, the displacement of the roller 6 can be limited from above; whereby the force locking connection is always maintained, the locking rod 9 is not fully extended and the entire actuator remains fixed. Here, too, this may be the beginning of the roll cut process so that a safe cut signal can be generated shortly before blocking.
