Definitions
- the invention relates to a filter housing for an intake filter of a motor vehicle for receiving a filter cartridge with a cylindrical housing wall and an outlet provided on an end face of the housing wall.
- a generic filter housing or a filter cartridge from DE 101 06 526 Al is already known.
- the cylindrical filter cartridge has a ring-shaped filter medium which forms the jacket of the filter cartridge.
- the filter medium has sealed end faces that serve to separate the raw and clean side. Fluid to be filtered is applied to the raw side, the filtered fluid flowing out on the clean side.
- a support tube is arranged in an interior space formed by the filter medium and has openings which communicate the filter medium with the interior space in a communicating manner. Furthermore, an elastic, annular end plate is provided, in which one of the end faces of the filter medium and one of the ends of the support tube are embedded.
- the invention is based on the object of designing and arranging a filter housing for liquids or gases in such a way that it has increased rigidity and strength as well as low weight and can be produced with low tool costs.
- the filter housing has a stabilizing part within the housing wall and the filter cartridge in the direction of the axis of the housing wall in the stabilizing part can be used. This ensures that the filter housing has sufficient rigidity and strength for certain materials.
- the housing wall and the stabilizing part are formed in one piece and identical to the material. Both parts are produced in a molding process without subsequent assembly.
- the filter housing is produced by rotational molding.
- the problem of stiffness and strength applies particularly to materials that are suitable for rotational molding. Such materials have a low modulus of elasticity and an unfavorable stability and rigidity behavior with increasing housing volume.
- the weight of the filter housing can be reduced by using such materials suitable for rotational molding.
- the production of the filter housing by means of rotary molding also has the advantage of low tool costs.
- a further possibility is that the stabilizing part and the housing wall are aligned coaxially and have at least one sealing surface arranged essentially parallel to the end face and the sealing surface is connected to the outlet. Because the stabilizing part has a sealing surface in the axial or in the direction of the axis of symmetry, the clamping forces necessary for sealing are absorbed by the stabilizing part. The materials used for rotational molding tend to stress relaxation. This disadvantage of a filter housing can be remedied by the double construction formed from the end face of the housing wall and the sealing surface of the stabilizing part. The clamping forces are absorbed without relaxation via the stabilizing part.
- the housing wall has a ring connection with the stabilizing part in at least one position over the entire circumference in the direction of the axis.
- the stabilizing part is connected to the housing wall at another point. This increases the rigidity and stability of the filter housing.
- the stabilizing part is point-connected to the housing wall at at least one point or has a point connection to the housing wall. It is thereby achieved that the stabilizing part designed as a grid and the housing wall are further stiffened. In addition, only a few sound bridges are built due to the point connections. This leads to an improvement in the sound insulation of the filter housing.
- the filter housing on the side of the housing wall opposite the end face has a cover which is symmetrical to the axis, the cover being sealingly attachable to the filter cartridge. This enables the use of conventional filter cartridges. At the same time, the filter cartridge is at least partially supported by the stabilizing part.
- the cover or the housing wall have a guide ring for the filter cartridge, which can be sealingly connected to the filter cartridge.
- Sealing the filter housing is simplified in the case of a filter cartridge which is closed in the axial direction on the side of the cover in that the filter cartridge seals in the radial direction not with the cover but with the housing wall.
- the filter cartridge has a rear frame part, which is also shaped in the form of a cover.
- the guide ring is provided in the cover and receives the filter cartridge in the radial direction. The cover is sealed off from the housing wall with an additional sealing element.
- the cover has at least one pretensioning part, with which the filter cartridge can be placed against the sealing surface in the direction of the axis. This ensures that the filter cartridge experiences the pretension necessary for contact with the sealing surface.
- the biasing part is rigid or resilient.
- the circumferential surface of the filter cartridge rests in the radial direction on the stabilization part in the area of the sealing surface of the stabilization part and that a gap is formed over the entire circumference in the radial direction in the area of the cover between the filter cartridge and the stabilization part.
- the flow conditions around the grille are improved by the gap.
- the surface of the filter cartridge is kept free in order to provide the largest possible filter area over the entire length.
- the filter housing 1 is designed as an air filter housing and has a cylindrical housing wall 2 which runs around an axis 3.3. The axial and radial directions are related to this axis 3.3.
- a filter cartridge 4 is provided within the housing wall 2.
- the air flow 9 flows into the radial direction via an inlet or unfiltered air connector 8 provided in the casing area of the housing wall 2 Filter housing 1 in and out of filter housing 1 in the axial direction via an outlet or clean air connector 7 provided on an end face 2.1.
- a filter cartridge 4 is provided within the housing wall 2 and is mounted in a stabilization part designed as a stabilization dome 3.
- the stabilizing dome 3 is formed in one piece and identical to the material with the housing wall 2 and connected to it at several points.
- the stabilizing dome 3 and the housing wall 2 are produced by rotary molding in a molding process.
- the lateral surface of the stabilizing dome 3 is constructed in a lattice shape from webs 3.5, 3.5 '.
- the air stream 9 flows through the grating opening 3.6 formed between the crosses 3.1 into the filter cartridge 4 and in the axial direction out of the center of the filter cartridge 4 via a corresponding opening.
- the webs 3.5, 3.5 ' form four radii 3.2 of several millimeters in length on each lattice cross 3.1.
- the grid openings 3.6 are round.
- the filter housing 1 is closed by a cover 5 opposite the end face 2.1.
- the stabilizing dome 3 like the housing wall 2, is connected to the clean air connector 7 via a ring connection 6.1 ′ over the entire circumference and forms an opening in the axial direction corresponding to the inside diameter of the clean air connector 7.
- the stabilizing dome 3 is in the area of the cover 5 over the entire circumference of the housing wall 2 with this another ring connection 6.1 connected.
- the stabilizing dome 3 has several
- a first point connection 6 is shown on the outer surface of the housing wall 2.
- the filter cartridge 4 is also cylindrical and rests with a front frame part 4.1 in the axial direction on a sealing surface 3.4 formed parallel to the end face 2.1. In the radial direction, the filter cartridge 4 in the area of the sealing surface 3.4 also rests with the front frame part 4.1 on the outer surface of the stabilizing dome 3.
- the stabilizing dome 3 tapered apart towards the cover 5, so that a gap is formed between the filter cartridge 4 and the stabilizing dome 3 in the region of the cover 5 over the entire circumference.
- the filter cartridge 4 is mounted in the cover 5 with a rear frame part 4.2 in the radial and in the axial direction.
- the cover 5 has a guide ring 5.1 with a cylindrical surface running coaxially with the filter cartridge 4.
- the cover 5 is centered on a thread 5.3 in the housing wall 2 and closes the axial opening for changing the filter cartridge 4.
- pre-tensioning elements 5, 5, 5 ' are formed in the cover 5 provided that come to rest when screwing the cover 5 with the filter cartridge 4 and press it in the direction of the sealing surface 3.4.
- the rear support part 4.2 seals at the same time as the coaxial support surface.
- the preload on the sealing surface 3.4 and the sealing guide ring 5.1 ensures that the air flow 9 does not flow past the filter cartridge 4 into the interior of the housing wall 2 and flows out of the clean air nozzle 7 without being filtered.
