- nes supporting body is embedded.
- a support body is provided, which in the end
- the flexibility of the end and sealing body is not limited and so des ⁇
- the embedded part of the support body a Dahl ⁇
- Ribs of the first flowable in a manufacturing process Ver ⁇ casting material can be flowed through and are filled in the final state with the solidified potting compound.
- the ribs give the otherwise elastic end body optimal dimensional stability, without its sealing function is impaired.
- the rings hold the ribs of the support body before embedding and provide additional stabilization of the finished end and sealing body.
- the ribs can run helically curved.
- a dynamic geometry of the ribs increases the safety in the manufacturing process. It is also achieved that the first flowable potting compound can flow around the ribs better and faster and thus the uniform distribution of the potting compound in the areas between the ribs is improved and air pockets are prevented.
- flanks of the ribs may be chamfered.
- the safety in the manufacturing process and the flow around the potting compound is further improved.
- the radially outer ring may be a hollow cylinder, wherein the ribs engage in the region of an edge of the hollow cylinder and the peripheral wall of the hollow cylinder, the FiI- termedium circumferentially in the area of the end face surrounds.
- the hollow cylindrical shape of the outer ring gives the support body additional stability in the axial direction.
- the support body can be fastened to the filter medium prior to embedding the filter medium with the support body in the potting compound and embedded together with the latter.
- the filter medium is guided in the hollow cylinder and centered and later held with the peripheral wall of the hollow cylinder.
- the support body may further comprise guide plates, in particular resilient latching noses, which extend axially to the filter medium.
- the guide tabs preferably the detents, can engage in corresponding depressions in the filter medium or even achieve an improved hold of the filter medium in the hollow cylinder merely by means of an increased contact pressure. As a result, the stability of the entire filter element is significantly improved, without affecting the sealing function of the elastic end body thereof.
- the embedded part of the support body may have projections for supporting the filter medium.
- still flowable potting compound optimally in all areas penetrate between the support body and the filter medium and between the folds of the filter medium, so that an optimal connection between the filter medium, the potting compound and the support body and the support body and an optimum sealing function is achieved.
- the support body may be made of plastic.
- Plastic support bodies are lightweight, can be produced easily and inexpensively, for example, cast or stamped. On metal can be dispensed with.
- the elastic potting compound may preferably be polyurethane foam.
- Polyurethane foam is easily flowable in the manufacturing process and spreads best between the filter medium and the support body, so that a homogeneous and reliable connection is formed.
- polyurethane foam is elastic, so that an optimum sealing effect is made possible.
- the first flowable potting compound is filled in a casting shell, a support body attached to the front side of the filter medium, the filter medium with the support body embedded in the potting compound and after the solidification of the potting compound Casting bowl separated from the filter element.

- FIG. 10 schematically shows a detail view of the support body from FIGS.
- housing 12 which is substantially coaxial with egg
- the inlet is with a radially outer inlet portion 16 of the housing
- the filter system 10 is used to filter the intake air of a
- a filter element 18 This has a star-shaped folded, total cylindrical filter medium 20.
- a coaxial center tube 21 is arranged, which has a plurality of passage openings for the purified air.
- the filter element 18 has elastic end and sealing body 22, of which in the figure 1, only the outlet side is shown. A detailed view of the outlet-side end side of the filter element 18 is shown in FIG.
- the end and sealing body 22 has a housing axis 14 to the coaxial opening 24. The air to be cleaned flows from the inlet portion 16 through the filter element 18 and cleaned via an outlet 26 of the housing 12 to the internal combustion engine.
- the end and sealing body 22 is made of an elastic potting compound of polyurethane foam. It has on its side facing away from the filter medium 20 a coaxial to its central axis, extending in the axial direction bead 28.
- the central axis of the end and sealing body 22 coincides in the assembled state of the filter system 16 with the housing axis 14.
- the radially inner flank of the bead 28 forms the inner peripheral side of the end and sealing body 22.
- the bead 28 extends in the radial direction about half of the end and sealing body 22nd
- the bead 28 has an annular groove 30 in its end remote from the filter medium 20.
- the bead 28 With a corresponding recess 32 in a bottom 34 of the housing 12.
- a ring collar 36 extending axially to the housing axis 14 on the bottom 34 engages in the annular groove 30.
- the bead 28 and the annular groove 30 thus cooperate sealingly with the recess 32 and the annular collar 36 and form a seal between the raw air area (inlet area 16) and the clean air area in the interior 38 of the filter element 18.
- the support body 40 is embedded in the potting compound of the end and sealing body 22, a support body 40 is embedded.
- the support body 40 is shown in detail in FIG.
- the support body 40 is made of a solid plastic. It has essentially the shape of a cylindrical, coaxial with the housing axis 14 pot, which is open to the filter medium 20.
- the pot bottom has a coaxial opening 42, which is slightly larger than the opening 24 of the housing 12.
- the opening 42 in the pot bottom is bounded in the radial direction by a radially inner ring 44.
- the pot bottom itself is formed by a plurality of spaced ribs 46, which extend between the radially inner ring 44 and the edge of a peripheral side of the support body 40 forming hollow cylinder 48.
- the ribs 46 are helically curved.
- Some of the ribs 46 have integrally formed, longitudinally interrupted projections 50 for supporting the filter medium 20 on their sides facing the interior of the pot.
- the projections 50 are distributed over the pot bottom of the support body 40 ange- assigns.
- FIG. 6 shows one of the ribs 46 with a broken projection 50 in a side view.
- the lateral flanks of the ribs 46 are chamfered, so that in the manufacturing process, the first flowable casting material flow well into the intermediate regions between the ribs 46 and can flow through them.
- two of the ribs 46 are shown in profile.
- the center tube 21 is placed in the folded filter medium 20 and the support body 40 is inserted with its open side on the end face of the filter medium 20, as shown in the figure 4.
- the peripheral wall 48 engages around the outside of the filter medium 20 in the region of the end face and the guide tabs 52 correspond to the central tube 21. In this way, the filter element 18 is already given a certain dimensional stability.
- first pourable polyurethane foam is filled as potting compound.
- the preassembled filter medium 20 is pressed with the support body 40 ahead in the potting compound in the casting bowl.
- the dynamic geometry of the ribs 46 in particular the distance between see the ribs 46, the tapered flanks, their helical course and the projections 50 that the still flowable polyurethane foam can quickly fill all gaps and is driven towards the front of the filter medium 20.
- the polyurethane foam fully embeds the ribs 46 of the support body 40 and creates a seamless tight bond between the support body 40 and the filter medium 20.
- the casting shell is separated from the finished filter element 18, which now has the solid, yet elastic end and sealing body 22, as shown in Figures 2 and 3.
- the finished filter element 18 can now be introduced in a known manner into the housing 12 of the filter system 10 shown in Figure 1.
- end and sealing body 22 instead of polyurethane foam also from another elastic, initially flowable potting compound.
- a second embodiment of a support body 40 is shown. Those elements that are similar to those of the first embodiment of Figures 1 to 7 are provided with the same reference numerals.
- the second embodiment differs from the first in that instead of the guide tabs 52 on the radially inner ring 44 each resilient guide and retaining tabs 152 are provided in the peripheral wall 48 of the support body 40.
- the leaders Retaining and holding tabs 152 have at their edge facing away from the bottom of the pot radially inwardly extending latching noses.
