Description
Technical Field
The invention relates to a filter connection assembly for a filter assembly for fluids, in particular oil or fuel, in particular for an internal combustion engine, in particular of a motor vehicle, having at least one connection portion for connecting at least one filter to the filter connection assembly and at least one mating flange for supporting at least one respective flange of the at least one filter, wherein the at least one mating flange has a mating flange base made of plastic and at least one reinforcing element, wherein the at least one reinforcing element surrounds the at least one connection portion circumferentially with respect to a connection axis of the filter connection assembly with the at least one filter, wherein the at least one reinforcing element has a mechanical strength which is greater than the mating flange base.
The invention further relates to a filter assembly for fluids, in particular oil or fuel, in particular for an internal combustion engine, in particular of a motor vehicle, having at least one filter and having at least one filter connection assembly, wherein the at least one filter connection assembly has at least one connection portion for connecting at least one filter to the filter connection assembly and has at least one mating flange for supporting at least one corresponding flange of the at least one filter, wherein the at least one mating flange has a mating flange base made of plastic and at least one reinforcing element, wherein the at least one reinforcing element circumferentially surrounds the at least one connection portion relative to a connection axis of a filter connection assembly having at least one filter, wherein the at least one reinforcing element has a mechanical strength greater than the mating flange base.
Background
An oil or fuel filter with a carrier is known, for example, from DE102013215243a 1. The bracket has an annular support flange onto which the filter housing can be placed tightly. The support flange is made of plastic and has an annular reinforcement in the region of the support flange, which at least reduces creep of the plastic on the support flange. The carrier is embodied as a plastic injection-molded part, wherein at least part of the reinforcement is injected therein. The reinforcement can be embodied, for example, as a metal ring or can also have fibers, in particular carbon fibers, glass fibers or aramid fibers (aramid fibers). The reinforcement is coated on all sides with plastic. Purely theoretically, an embodiment is also possible in which the reinforcement is coated on the inner periphery of the support flange without plastic and is therefore in direct contact with the fluid to be filtered.
The basic object of the present invention is to create a filter assembly and a filter connection assembly of the above-cited type, wherein a more secure connection between the at least one filter and the at least one filter connection assembly, in particular with respect to pressure and/or pressure differences, can be achieved in a simple manner. In particular, the tightness of the connection should be improved, in particular guaranteed during standing time.
Disclosure of Invention
This object is inventively achieved by: the at least one reinforcement element forms at least one contact surface for supporting at least one sealing section and/or at least one corresponding section of at least one filter.
According to the invention, the at least one mechanically stiffened reinforcing element is provided with a contact surface on which the at least one sealing section and/or at least one corresponding section of the at least one filter is supported, and via which a connecting force and/or a sealing force from the at least one filter and/or seal can be guided into the filter connection assembly, and vice versa.
At least one contact surface can advantageously be realized as a sealing surface at least in sections. The respective sealing section may be placed tightly against the sealing surface. The at least one sealing section may be fixedly or releasably connected to the at least one filter. The at least one sealing section may advantageously be part of a seal. The seal may be arranged between the flange of the filter and the at least one contact surface of the at least one reinforcement element.
The joining force can advantageously be a tensile force and/or a compressive force. The connection force may advantageously be oriented axially to the connection axis. By means of the connecting force, a corresponding sealing force or sealing reaction force is achieved, enhancing the sealing function of the at least one sealing section.
By means of the inventive filter connection assembly, in combination with a filter flange, in particular a conventional spin-on flange, it is possible to prevent deformations occurring in the support region of the spin-on outer seal at the respective plastic mating flange due to axially acting sealing reaction forces that may occur in conventional plastic flanges. Such deformations may occur because, due to normal critical installation space conditions, it is not possible to design a filter connection assembly (especially a plastic module) such that over time it can withstand the mechanical challenges arising from attaching (especially screwing on) a filter (especially a conventional spin-on filter). Thus, filters of this type have heretofore typically been placed (especially screwed) onto an aluminum mating flange. According to the invention, a plastic solution is proposed, in which a corresponding stable mating flange is provided in the process, based on a combination of two or more materials.
In an advantageous embodiment, the at least one stiffening element may be fixedly connected to the at least one mating flange base. In this way, it is possible to achieve a stable positioning of the at least one reinforcing element. Furthermore, in this way, forces between the at least one reinforcing element and the at least one mating flange base can be transmitted more reliably.
The at least one mating flange base and the at least one reinforcing element may advantageously be realized as so-called multi-part parts, in particular two-part parts.
The mating flange base comprises plastic. The plastic part, even with a complex construction, is simple to produce. The plastic part can be realized with a lower weight than the metal part.
In a further advantageous embodiment, the at least one mating flange base may have or comprise at least one thermoplastic. Thermoplastics are easy to process, especially by means of the addition of heat.
According to the invention, at least one reinforcing element comprises or comprises at least one composite material, in particular a thermoplastic material. The composite material of the at least one reinforcing element may be stronger than the plastics material of the base of the mating flange.
In a further advantageous embodiment, the at least one reinforcing element can have or comprise a material which can have a filler material (in particular fibers). In this way, the stiffness of the at least one stiffening element can be improved.
The material of the at least one reinforcing element can advantageously have glass fibers, carbon fibers, aramid fibers or the like. The fibers are easy to process.
The at least one reinforcing element may advantageously comprise, or at least have, a so-called high-performance material. By means of the material, in particular a greater resistance to temperature influences, chemical influences and/or mechanical influences can be achieved in the at least one reinforcing element.
In a further advantageous embodiment, the at least one material of the at least one reinforcing element has a filling level of at least 30%, in particular at least 35%, of the filling material. In this way, the properties of the at least one reinforcing element can be further improved.
In a further advantageous embodiment, the at least one connection portion may be directly connected to the at least one mating flange base and/or the at least one stiffening element. In this way, it is possible to achieve a stable retention of the at least one connection portion on the mating flange.
The at least one connection portion may advantageously be partially connected to the at least one mating flange base. In this way, a corresponding connection force from the at least one connection portion can be directly transmitted to the at least one mating flange base. Alternatively, or in addition, the at least one connection portion may be partially connected to the at least one reinforcement element. In this way, a corresponding connecting force from the at least one connecting portion can be transmitted directly to the at least one reinforcing element. The mating flange base can thus be mechanically loosened accordingly (relieved). Alternatively, on the side of the filter connection assembly, the at least one connection portion may be connected exclusively to the at least one mating flange base or exclusively to the at least one reinforcement element. In this way, the mechanical load of the other part to which the at least one connection part is not connected can be reduced.
In a further advantageous embodiment, the at least one connection portion may be at least partially embedded in the material of the at least one mating flange base and/or in the material of the at least one reinforcement element. In this way, a stable mechanical connection between the at least one connection portion and the at least one mating flange base and/or the at least one reinforcement element may be allowed.
The material and/or structure of the at least one connection portion on the one hand and the material and/or structure of the mating flange base and/or the at least one reinforcing element on the other hand may penetrate into each other for connection. One of the parts, in particular the at least one connecting part, may advantageously be at least partially embedded (in particular injected and/or cast) in the material of the other part (in particular the mating flange base and/or the at least one reinforcing element) or may thus be covered (in particular thus cast or coated). In particular, the at least one attachment section of the at least one connection portion may be partially embedded in the material of the respective further portion.
In a further advantageous embodiment, the at least one connection portion may be partially mounted in the at least one mating flange base and/or the at least one reinforcement element. In this way, the at least one connection portion may also be subsequently connected to the at least one mating flange base and/or the at least one reinforcing element.
The at least one connection portion may advantageously be releasably mounted in a corresponding receiving element (in particular a receiving opening) of the at least one mating flange base and/or the at least one connection portion. In this way, at least one connection portion can be removed or replaced, in particular for possible maintenance purposes. Alternatively, the at least one connection part can be mounted accordingly in such a way that it cannot be released without damage.
The at least one connecting portion may advantageously be mounted in the receiving element by means of a rotatable and/or insertable connecting piece. The connection is simple to implement and can be released when required.
In the context of the present invention, the rotatable and/or insertable connection may in particular be a threaded connection, an insertion connection, a snap-on connection and/or a connection with a bayonet closure.
In a further advantageous embodiment, the at least one connection portion may realize at least a part of a fluid connection of the filter connection assembly to the fluid guiding portion of the filter. In this way, the at least one connection portion may directly represent a fluid connection to the filter. In this way, the complexity of the respective fluid connections may be reduced. Thus, in particular, the complexity and/or space requirements during production and assembly may be reduced.
The interior of the at least one connection portion may advantageously be hollow, in particular tubular. In this way, the at least one connection portion may at least contribute to the formation of a fluid line, in particular a fluid outlet or a fluid inlet. By means of the at least one connection portion, the fluid channel (in particular the fluid outlet or the fluid inlet) of the filter may be connected to a fluid line (in particular the fluid outlet line or the fluid inlet line) of the fluid connection assembly.
The at least one connection part can advantageously have at least one connection section which can be connected directly or indirectly to at least one respective filter-side connection element on the side of the filter, in such a way that it can be released or not without damage. The connecting section may advantageously be a part of a rotatable and/or insertable connecting piece, in particular a part of a threaded or bayonet connection.
The at least one head-side connecting element may be realized as a male or female part of a rotatable and/or insertable connecting element.
The head-side connection element can advantageously be realized as a threaded opening with an internal thread or as a pipe connection with an external thread or as a threaded bolt.
The at least one filter may advantageously be a so-called exchangeable filter. In the exchangeable filter, the at least one filter element may be arranged in a housing pot (housing pot) of the filter housing. The replaceable filter may be completely replaced with the filter housing and at least one filter element contained therein. The replaceable filter may also be embodied as and/or be referred to as a spin-on filter, a twist-on filter, and in particular a screw-on filter.
The at least one filter element can advantageously be arranged fixedly in the filter housing. Alternatively, the at least one filter element may be arranged interchangeably in the filter housing.
The filter may simply be connected to the at least one connection portion at the at least one filter connection assembly.
The at least one filter connection assembly may advantageously have at least one fluid line for fluid to be filtered. The at least one filter connection assembly may advantageously have a fluid inlet line for fluid to be filtered and/or a fluid outlet line for filtered fluid. The at least one filter connection assembly may advantageously be part of a filter module, in particular an oil filter module. Alternatively or additionally, the at least one filter connection assembly may be fixedly connected to a holding part, in particular a frame part, of the fluid system.
The filter device, in particular the oil filter module, may advantageously be part of an engine oil circuit of an internal combustion engine of a motor vehicle. The at least one filter may be an engine oil filter for filtering engine oil supplied to the internal combustion engine. Alternatively, the filter assembly (in particular the fuel filter module) may advantageously be part of a fuel system of an internal combustion engine of a motor vehicle. The filter connection assembly may be attached to a frame part of a motor vehicle or an internal combustion engine. However, the present invention is not limited to a filter assembly for a fuel system or an engine oil circuit of an internal combustion engine of a motor vehicle. Conversely, it can also be used in other fluid systems of motor vehicles or other engines, in particular in water-conducting systems, hydraulic systems, systems for urea solutions or air-conducting systems. The filter assembly can also be used outside the field of motor vehicles, in particular in industrial motors.
The at least one connecting portion may advantageously have or comprise a material which is reinforced compared to the material of the mating flange base and/or the material of the at least one stiffening element. In this way, the at least one connection portion can better resist mechanical connection forces. A greater mechanical coupling force can be applied.
At least one connecting part can advantageously have or comprise at least metal (preferably aluminium or steel) and/or reinforced plastic (preferably high-performance thermoplastics and/or thermosets or glass fibre reinforced plastics or mixtures of different reinforcing materials).
Furthermore, the technical object is achieved in the filter assembly in that the at least one reinforcement element also forms at least one contact surface for supporting the at least one sealing section and/or the at least one respective section of the at least one filter.
Furthermore, the features and advantages detailed in connection with the inventive connection assembly and the inventive filter assembly and each advantageous embodiment thereof may be applied accordingly and vice versa. The individual features and advantages can of course be combined with one another, wherein additional advantageous effects can be produced which extend beyond the sum of the individual effects.

Further advantages, features and details of the invention emerge from the following description, wherein exemplary embodiments of the invention will be explained in more detail using the figures. Those skilled in the art will also consider combinations of features disclosed in the drawings, the description and the claims, taken alone, and will use them to produce additional useful combinations. In the schematic drawings:
fig. 1 depicts a longitudinal cross-section of a filter connection assembly for a fluid filtration module of a fluid system in an internal combustion engine to which a replaceable spin-on filter may be attached;
in the drawings, like parts are provided with like reference numerals.
Detailed Description
Fig. 1 depicts a longitudinal cross-section of a filter connection assembly 12 in the form of a filter head (head) of a fluid filtration module. The fluid filtration module is used for filtering a fluid, in particular engine oil, fuel or another operating fluid or air, in an internal combustion engine of a motor vehicle. The fluid filter module is arranged in a fluid system (not shown otherwise), such as an engine oil circuit or a fuel system of an internal combustion engine.
A filter (not shown in the drawings) may be replaceably attached to the filter connection assembly 12 at the top of fig. 1. The filter connection assembly 12 is connected to an internal combustion engine.
The filter connection assembly 12 comprises a connection portion 14 in the form of a pipe connection for connecting the filter to the filter connection assembly 12 and a mating flange 16 for supporting the flange of the filter.
The mating flange 16 has an inlet channel covered in the figure and an outlet channel 18 for the fluid. The outlet channel 18 is coaxial with the axis 20 in its end region facing the filter. Outside the fluid filtration module 10, the inlet and outlet channels 18 are connected to respective fluid lines of a fluid system in a manner that is not of further interest here.
In the exemplary embodiment, axis 20 is coincident with a filter axis of a filter and a connection axis of a filter having filter connection assembly 12. A connecting force (basically a pulling force and a pressing force in the exemplary embodiment) acts on the filter connection assembly 12 from the filter via the connection portion 14 in the direction of the connection axis.
For better understanding, said filter axis and connection axis will be indicated hereinafter with the same reference numeral 20 and will be known simply as axis 20. It is to be understood that when the filter is disassembled, the filter axis and/or the connection axis are meant according to the context. Subsequent discussions of "radial," "coaxial," "axial," "circumferential," etc., are made with respect to the axis 20 unless otherwise indicated.
The filter is embodied as a replaceable filter, which can also be referred to as a spin-on or twist-on filter. The filter may be connected to and disconnected from the filter connection assembly 12 by way of the connection portion 14 using a combined twisting/attaching motion about the axis 20 (shown in the exemplary embodiment as a screwing-on motion).
The mating flange 16 has a mating flange base 22 and a reinforcing element 24. The mating flange base 22 and the reinforcing element 24 are realized as two component parts. The reinforcing element 24 is thus fixedly connected to the mating flange base 22.
The mating flange base 22 is disposed on a connector side of the filter connection assembly 12 that faces axially away from the filter. It has a section of the outlet channel 18 coaxial with the side of the connector and a section of the inlet channel not shown in fig. 1. On the side axially facing the filter, the mating flange base 22 is fixedly connected to a reinforcing element 24.
The reinforcing element 24 surrounds a receiving opening 26 for the connecting portion 14 and thus circumferentially surrounds the connecting portion 14 relative to the axis 20. The receiving opening 26 is coaxial with the axis 20. The reinforcement element 24 forms an annular coaxial contact surface 28 at a radially outer portion for supporting a respective sealing section of the annular seal. The annular seal seals the corresponding flange of the filter from the environment against the mating flange 16 of the filter connection assembly 12. Said contact surface 28 is arranged on the end face of the reinforcing element 24 facing the filter. Which is coaxial with the axis 20.
The section of the inlet channel which is covered in the figure, which is open to the side facing the filter, is arranged radially between the receiving opening 26 for the connecting part 14 and the contact surface 28.
The connecting portion 14 is open at both ends. The connecting portion 14 is arranged coaxially to the axis 20 in a receiving opening 26 of the reinforcing element 24. The connecting portion 14 is implemented as a separate part. The connecting portion 14 is made of metal, for example aluminium or steel, which has a reinforcing effect compared to the material of the reinforcing element 24 and the mating flange base 22.
The connecting portion 14 has an attachment section 30, which attachment section 30 is enclosed by the material of the reinforcing element 24 and is embedded therein. By means of the attachment section 30, the connection portion 14 is fixedly connected to the mating flange base 22 of the filter connection assembly 12 via the reinforcement element 24. In its radially outer circumferential side, the attachment section 30 has a plurality of circumferential grooves 32 in which the material of the reinforcing element 24 can engage.
One end of the connecting portion 14 protrudes out of the reinforcing member 24. There, the radially outer circumferential side of the connecting part 14 has an external thread 34. The connection part 14 is screwed by means of an external thread 34 into a threaded opening coaxial with the filter side (for example of the housing cover of the filter). The connection portion 14 thus indirectly releasably connects the filter connection assembly 12 to the filter. The connection portion 14 enables fluid connection of the filter connection assembly 12 to a fluid conducting portion of a filter.
The filter has, for example, a coaxial filter housing with a housing pot closed with a housing cover. The housing cover has a coaxial filter side threaded opening that also forms an outlet for the filtered fluid filter. The housing cover furthermore has a plurality of eccentric inlet openings through which the fluid to be filtered can flow into the filter housing.
In terms of flow engineering, a filter element (not of further interest here), for example in the form of a circular filter element, is arranged coaxially between the inlet opening and the threaded opening of the filter, so that it separates the threaded opening from the inlet opening. When the filter is mounted, the element interior of the filter element is connected to the threaded opening of the filter side and to the interior of the attachment portion 14.
An annular seal supported on the contact surface 28 surrounds the threaded opening and the inlet opening when the filter is installed.
