A cartridge pack of this type has been disclosed in European Patent No. PB 438 624. This packaging it is used for the measurement of the rotational speed between two pieces that rotate in reciprocal relationship r < They serve as support and support for a motor vehicle wheel. The relative rotational movement between two rings is especially captured. For this, a pulse emitter and a sensor are arranged. These components are installed on the outside of the cartridge package. Through this, additional space is required for the installation, which is "inefficient". 'It is also difficult to establish the correct reciprocal arrangement and * -' to guarantee it in the long term. Both the sensor and the pulse emitter are exposed to the effect of dust and environmental impurities, which may result in erroneous pick-ups of measurement values. The task of the present invention consists in * = - perfecting a cartridge package of the type mentioned, in such a way that the disadvantages can be avoided * 'U - of the system according to the current state of the technology. This task finds its application in accordance with the present invention with a cartridge package in accordance with the main concept through the details i * characteristic of the first claim. The secondary claims deal with advantageous configurations. In the case of the cartridge package according to the present invention, it is provided that the sensor and the pulse emitter are disposed at least partially in the hollow space defined by the rings and the sealing lip. This has the advantage that additional space can be dispensed with and that the decisive components of operation are well protected from environmental influences. For this it is also possible that the pulse emitter and the sensor are completely arranged in the hollow space defined by the rings and the sealing lip. Of special advantage here is the optimum protection of the secondary influences of the environment. % The first ring can have recessed ditches in a perimeter direction, which are separated by bridges and form with them the pulse emitter. Bridges generate as they pass through the sensor during the relative rotational movement respectively a signal that is picked up in the co sensor or impulse and that is transferred to an evaluation device. In this case it is -i environment in the area of the intermediate space is made difficult through it. The possibility of capturing signals in the most optimal way is also increased. The annular groove may also have the configuration of a labyrinth. With this you can get a good performance of hermetization. * A further embodiment of the cartridge package may be that the site at which the annular groove is angled is separated by it. less than five times of the outside air more than the sensor of the pulse emitter. This is temporarily delayed 1 and the penetration of impurities in the intermediate space is prevented. With "the purpose of improving the assurance against environmental influences, a possible embodiment can consist in that the intermediate space is limited on at least one side by t means of a buffer space free of currents, It can be obtained through it improved conditions in the long term in the capture of the impulse, since the impurities that reach the zone of the intermediate space are no longer deposited in the same but in the neighboring areas free of glasses. For this, no additional mounting effort is necessary. The variation of this and the way of Thus, for example, the arrangement of the two pick-up elements as well as the pulse emitter and the sensor can take place in such a way that the intermediate space on both sides is limited by a free buffer space fl ^ of currents The ratio of the total volume of the buffer space to the intermediate space between the sensor and the pulse emitter should be at least the OS With the cartridge packing according to 1 > The present invention provides a device which, in addition to the package, comprises a pulse emitter and a sensor such as T t, a self-contained and robust structural unit, through the use of the pulse emitter and the sensor within the * Cartridge packaging makes simple construction possible and accurate signal acquisition. The manufacture of The aforementioned cartridge system does not require any complicated assembly construction stage and is economical with respect to the capture and processing of the signal. Taking into account the drawings you can see «. Below are some embodiments of the cartridge packaging according to the present invention in a more detailed manner. t It is shown in Figure 1 The integration of the pulse transmitter and the 1 feensor * in a cartridge package with realization of the impulse transmitter. Figures 2 and 3 are embodiments of the arrangement 3 of the pulse emitter and the sensor with embodiment of the pulse emitter. Figures 4 and 5 representation of pulse emitters as ring elements. Figures 6 and 7 a lip of het ionization with a pulse emitter fixed therein. Figures 8 to 10 cartridge packaging for rotary axes. Figures 1 to 7 refer to forms of real I in which is the an i l l 1 g go and the an i l l 4 is static. Figures 8 to 10 describe cartridge packages for rotating shafts. In Figure 1 there is illustrated a cartridge package comprising two rings indicated respectively with 1 and 4. These rings are essentially limited by an angular profile. The two rings 1 and 4 are inserted recessively and jointly define a hollow space 10. The ring has a sealing lip indicated with 3. The lip of he et izac ion $ r 3 touches an i l l or 4 in g reative. In the indigo 4 there is disposed a sensor indicated with 6 for the capture of the relative rotation, in such a way that this sensor 6 t 'finds me placed through a sensor assembly 5, a? t through which the sensor 6 can be connected in electrical communication with, a control element. In the ring 1, a pulse transmitter indicated with the *. The disposition of the two elements 6 and 7 takes place in accordance with the present invention in such a way that they are at least partially arranged in the hollow space 10 defined by the invention. ring 1, ring 4 and ring 1 of herme ization 3. Through this, the sensor 6 and the pulse emitter 7 are integrated into the cartridge package without having to prepare additional space. It is also possible to avoid in a better way possible falsifications of the results of the measurements caused by the environmental influences. For this the impulse transmitter * 7 and sensor 6 can be completely recessed. - - «, completely in the hollow space 10 that define the rings ity 4 as well as the sealing lip 3, In Figure 1 the ring 1 is provided with notches distributed t uniformly in the direction pe imetr lls which are separated by bridges. The bridges act as the emitter t of impulses 7. They can be ambien i '- I! magne hoisted The sensor 6 may have, for example, the t Hall effect sensor configuration. This captures the impulses and supplies them to a central control element. On the basis of this embodiment, axial tolerances and movements can be compensated for, for example, by attack due to temperature., assembly and / or normal use. In FIG. 2, the pulse transmitter 7 is "• r" "t configured as a metal ring. It may also be composed of a ring of magnetizable synthetic material. An additional possibility consists in configuring the pulse transmitter 7 as a spring element. The pulse emitter can be connected during the vulcanization connection of the ring lip of the sealing lip by means of glue with the ring. The sensor 6 and the pulse emitter 7 are protected in all embodiments from environmental influences such as dust, mud, water and thus from corrosion. The pulse transmitter 7 and the sensor 6 are separated by an intermediate space S. This intermediate space 8 makes possible an optimal capture of the pulses and is i * "separated from the external air by an annular slot indi cated with, 7 the number 11. The size of the intermediate space 8 is for this variable effect. "Figure 3 the cartridge package has a t configuration similar to that of Figure 2. The emitter of * pulse 7 is configured as a metallic ring. _, It can be seen in the illustration of the metallic ring that this has divisions per imetral is. The divisions can be practiced in an exact and simple way or by using a punching method. The coordination of the sensor & with the pulse emitter 7 takes place at an i? special angle, which will preferably be 45 °. This has the decisive advantage that in case of an axial displacement of the two elements 7 and 6 the intermediate space 8 is correspondingly altered little. However, the pulse pick-up can take place in an optimum manner. A further embodiment is shown in FIGS. 4 and 5. The sensor £ is integrated into the ring 4 and receives the radial signal. . The pulse emitter 7 in this embodiment is shown as a sealed annular element, which is magnetizable and is connected to. the indigo 1. In Figures 6 and 7 it can be seen that the sensor 6 is integrated into the ring 4. The transmitter ~ t of impulses 7 is connected to the sealing lip of the ion , l n d l? d? c n 3..
