Description

ADAPTER FOR A BRAKE DISC / BUCKET COMBINATION AND 'BRAKE DISC / BUCKET COMBINATION DESCRIPTION OF THE INVENTION The invention relates to a brake / bucket disc combination in accordance with the preamble of claim 1 as well as to an adapter of a brake / bucket disc combination in accordance with the preamble of claim 20. A combination of a brake disc / hub with an internal ventilation brake disc is known from DE 199 18 069 A1. It describes a connection of the brake disc with a hub of the brake disc by means of the adapters through the brake disc. which takes place a transmission of braking moment of the brake disc to the hub of the brake disc, being that the adapters with one pin are in contact with a support element of the disc brake associated and with the other pin with a cam of the brake disc hub. The adapters known from this publication comprise two wings with a smooth surface extending mutually parallel and abutting in the operating position, which are formed by bending a sheet metal strip. In principle, this known construction has proven itself, but nevertheless under certain circumstances disassembly of the adapters may be somewhat difficult since, for example, due to corrosion in the brake disc support elements and / or the cams of the brake disc hub requires a relatively high force to be thrown out of the adapters, and this along the entire launch path. Also a contraction of the brake disc can cause a seizing of the adapters, due to which it is only possible with a corresponding expense to remove them from this indefinite pressing adjustment. The object of the present invention is therefore to develop the adapters of a brake disc / hub combination with simple construction means so that their disassembly is easy even under difficult conditions. This problem is solved by a brake / bucket disc combination having the features of claim 1 and by an adapter of a brake / bucket disc combination having the features of claim 20. By the possibility of decreasing the thickness total of the adjoining flanges of the adapters for the disassembly eliminates the pressing fit of the mounted adapters which is important for an optimal transmission of the braking moment, so that they can be dismounted without hindrance. This also practically undoes a corrosion seizing of the adapters with the abutting support elements and the cams, so that the dismantling problems described for the prior art are no longer the result. In this respect, the advantages deriving from this are particularly noteworthy, in particular also with regard to a minimization of costs by virtue of which a replacement of the wear parts of the disc brake can be effected without hindrance to a minimum. of time. The minimization of costs is not only due to the easy disassembly of the adapters but also because of the economics of their manufacture, because they are easily manufactured as stamped parts. In particular by virtue of the large quantities of parts in which these adapters are used, this fact is of particular importance. According to a favorable refinement of the invention, it is proposed that the total thickness reduction of the adjoining wings be carried out by means of projections and recesses which, in the operating position of the adapter, are not in mutual intervention, but in order to remove the adapter, they move relative to one another in such a way that they cover one another, the dimensions of the base surfaces of the shoulders being at least a little smaller than the associated notches.

By this the projections penetrate through the recesses after a displacement parallel to the axis of the wings, while outside of intervention they act as spacers. This position separated from the wings relative to each other corresponds to the mounting position 'in which the adapters are in press-contact against the cams of the hub of the brake disk and the supporting elements of the brake disk. To undo this tension to extract the adapters, a short relative movement of one pin relative to the other is sufficient, whereby the aforementioned tension is suppressed and the adapter can be easily removed. The fabrication of the recesses and ridges can be carried out in a very simple manner, for example by embossing rims by means of which the ridges are formed on the one hand and the recesses on the other hand. It is conceivable to configure the adapters in one piece or two pieces, since the notches at all points can be through, that is, they exist as through openings. The shape of the recesses and mutually corresponding projections can in principle be freely chosen. The important thing is that in the direction of travel of one pin relative to the other of the adapters, they are arranged one after the other in the position of function, and that their peripheral contour corresponds approximately to that of the others. The favorable refinements of the invention are characterized in the dependent claims. The embodiments of the invention are explained below by means of the attached drawings. - They show: Figure 1 a brake / bucket disc combination according to the invention in an exploded view; Figure 2 an example of an adapter in a perspective view; Figure 3 the adapter according to figure 2 in exploded view; Figures 4-8 in each. In the case of a further exemplary embodiment of an adapter in perspective representation. FIG. 1 shows a brake disk / hub combination comprising a brake disk 1 and a brake disk hub 2 which can simultaneously be configured as a wheel hub or be mounted on a separate hollow cylindrical wheel hub. The internally ventilated brake disc 1 comprises two friction rings 5, 6 which are connected to one another by bridges 7. For the transmission of the torque, the supporting elements 8 are formed on the internal circumference of the brake disc 1. they extend radially to the interior, which are arranged spaced one from the other and evenly distributed over the circumference. The hub 2 of the wheel has a hollow cylindrical section 9 in the manner of a bell at one end of which a disc 10 provided with perforations is added. 11. The end 13 of the section 9 remote from the disk 10 has, distributed on the outer circumference, cams 12 that protrude radially to the outside. The brake disk 1 can be axially drilled on the brake disk hub 2, the cams 12 and the support elements 8 intervene in each other in the circumferential direction. Between the cams 12 and the support elements 8 intermediate spaces are formed inside which the adapters 3 are pushed. The braking moment that becomes effective during a braking is transmitted by the support element 8 of the brake disc 1 the cams 12 of the brake disc hub 2 through the adapters 3. An axial safety of the brake disc 1 on the brake disc hub 2 or section 9 is effected on the pin facing the disc 10 by means of projections 15 that are directed radially to the outside, formed in the cams, against which the stops 16 of the brake disk 1 that are radially directed to the interior rest. To secure the brake disc 1 in the opposite direction, a safety ring 4 is provided in this case which rests inside annular slots 14 which are arranged around the cams 12. Otherwise, the safety ring 4 ensures the 3 adapters inserted against an axial displacement. Figures 2 and 4 to 7 show different embodiments of the adapters 3, which in each case comprise two adjacent wings 17, 18 extending parallel to one another. The embodiment example shown in the figures 2 and 3 of an adapter 3 has two-part configuration, ie the two wings 17, 18 are not connected materially. This can be seen very clearly in particular in FIG. 3. It can also be seen in this section that the lug comprises several recesses 20 in the form of through openings in the shape of an oblong hole, while in lug 17 there are provided projections 21 that they are configured high in the direction of the pin 18. In the use position, that is when the adapter 3 is incorporated in the intermediate space formed between the associated cam 12 and the support element 8, the lower part of the pin 18 it rests outside the recesses 20 on the shoulders 21. By moving the pin 18 relative to the pin 17 in the direction identified by the arrow in FIG. 2, the recesses 20 come to be covered with the shoulders 21 that the shoulders 21 intervene in the recesses 20, so that the shoulders 21 no longer constitute a support, but that both base surfaces of the wings 17, 18 are directly connected to each other. you superimposed. As can be seen, the total thickness of the wings 17, 18 is reduced by the penetration height of the shoulders 21 in the recesses 20, so that the mentioned intermediate space in which the adapter 3 is mounted has a thickness which then is greater than the total thickness of both wings 17, 18. Therefore, it is possible to extract the adapter 3 with the various dimensions without problems so much. To facilitate the assembly, the pin 18 has at its end a nose 23 facing toward the pin 17 that intervenes in a nose opening 25 of the pin 17, however, in the direction of displacement of the pin 18 so much slack is provided which allows a relative displacement of the pin 18 relative to the pin 17 without any problems. In an angular portion 19 of the pin 17 an insertion opening 24 is provided in which a tongue 22 of the pin 18 intervenes. By means of a suitable tool a displacement pressure can be exerted on the pin 22, so that the pin 18 can be displaced in the direction of the arrow from a use position to a disused position. In addition, both the recesses 20 and the shoulders 21 extend longitudinally transverse to the direction of travel. In figure 4 the adapter 3 is represented as a component of a piece in which both legs 17, 18 parallels are connected materially by means of a joining piece 27, or respectively folded on one another. The production of the adapter 3 or the deformation of the lugs 17, 18 can be effected by means of a fold or the like of the sheet metal strip. The connecting piece 27 preferably has a smaller width than both lugs 17, 18, so that the displaceability of the lugs with respect to one attachment is easier. Each pin 17, 18 comprises projections 21 which, in the position of use represented, rest directly on one another. Adjacent to the shoulders 21 are the recesses 20 which are practically formed by the production of the shoulders 21 and which are preferably stamped in the form of grooves. Through the action of a force on the angular part 19 of the pin 17 or an angular part 26 of opposite orientation of the pin 18 a relative displacement of the lugs 17, 18 relative to one another is obtained, with deformation of the piece 27 of joining, to disassemble the adapter 3, so that the shoulders 21 move out of their common covering area until they reach a zone in each case of covering with a notch 20 and penetrate it, thereby reducing the total thickness of both lugs 17, 18 superimposed. This is also the case in the exemplary embodiment of an adapter according to FIG. 5, which in relation to the arrangement and shape of the recesses 20 and of the projections corresponds to those of FIGS. 2 and 3, while both tabs 17, 18 are also connected from one piece to another by means of a deformable connecting piece 27. The additional embodiment examples of an adapter 3 shown in FIGS. 6 and 7 are configured like those shown in FIGS. 4 and 5 as a one-piece construction component, wherein the pins 17, 18 of the adapter 3 according to FIG. figure 6 correspond in their configuration with those of figure 5 and those of figure 7 with those according to figure 4. In both cases the pins 17, 18 have added angular parts 28, 29 on the opposite side of the piece 27, which extend in the same direction and parallel to each other, each angular portion 28, 29 corresponding in width to approximately the width of the adjacent angular portion and together to the total width of the adapter. Figure 8 shows an adapter that in its basic structure corresponds to that of Figure 6, that is, the pins 17, 18 have added angular parts 28, 29 that extend in the same direction and parallel to each other. In contrast to the exemplary embodiment according to FIG. 6, the recesses 20 are provided in the lower pin 17 with respect to the direction of extension of the angular portions 28, 29, while the projections 21 are manufactured by stamping the pin. 28 upper and protrude towards lower leg 17. In figure 8 it is only possible to appreciate the grooves that occur when stamping the shoulders 21.
