The invention refers to a joining means for joining at least two piping elements, and to a fluid joint assembly and to a motor vehicle with such a joining means.
The invention also refers to a method for joining at least two piping elements, an assembly with such joining means and a motor vehicle with such assembly.
In particular in limited spaces, as for example in an engine compartment of a car, it may be difficult to mount and connect a fluid line. From the state-of-the-ad it is known that piping elements may be joined to each other or to other components by the use of an auxiliary rubber hose that -with each of its ends -is attached to one of the piping elements to be joined, and by its own length increases the total piping length.
It is an object of the invention to provide an improved joining means and fluid joint assembly for such a joint, and an improved method for joining at least two piping elements.
This object is achieved by a joining means comprising the features of claim 1. Claim 8 is directed to a fluid joint assembly with such a joining means, claim 13 to a motor vehicle with such a joining means. This object is also achieved by a method for joining at least two piping elements according to claim 14. Embodiments are defined in the respective dependent claims.
According to one aspect of the invention, a joining means comprises a sealing means for sealed joining of a least two piping elements arranged with an axial overlap within the sealing means, and a securing means for compressing the sealing means, wherein the sealing means comprises an inner recess portion for receiving one of the piping elements and an outer recess portion axially overlapping the inner recess portion for receiving another one of the piping elements.
Thereby, a joining means consuming less space may be provided according to an embodiment. This may allow for offering a joining means with improved sealing and/or less parts. Thus, a more secure, flexible and/or easier to assemble joining means may be achieved according to an embodiment.
The sealing means may comprise one or two or more sealing elements. A securing means may comprise one or two or more securing elements.
The sealing means may comprise more than one outer and/or inner recess portion1 in particular in embodiments, in which more than two piping elements are to be joined to each other. According to different embodiments, a joining means joining three piping elements comprises two inner recess portions and one outer recess portion or one inner recess portion and two outer recess portions. In an analogous way, various combinations of outer and inner recess portions are within the scope of further embodiments for joining more than three piping elements.
According to an embodiment, one of the recess portions, in particular an inner recess portion, extends axially, in particular all the way, through the sealing means, which in particular allows for fluid communication through the sealing means.
Thereby, an appropriate or predetermined, in particular laminar, flow of fluid through the joining means may be provided, in particular whilst only securing the joint at a predetermined axial extension of the joining means.
According to an embodiment, at least of the recess portions, in particular an inner and/or an outer recess portion, is formed as a blind or stud hole, which in particular allows for an axial positive or form fit of a piping element received by said recess portion.
According to an embodiment, the sealing means contains a rubber material, in particular is made from such a material. At least one of the piping elements may contain a plastic and/or metal material, in particular may be made from such a material.
This allows for a secure and/or easy assembly and/or disassembly of sealing means and piping elements according to an embodiment.

According to an embodiment, the securing means is arranged on a radially outer surface of the sealing means. Thereby, an easier and/or more secure assembly of the joining assembly may be achieved.
According to an embodiment, said radially outer surface of the sealing means may be a, in particular outermost, peripheral surface of the sealing means, which may have an axial extension allowing for bearing or holding the securing means.
According to an embodiment, the sealing means, in particular on its outer surface, comprises at least one radial protrusion and/or recess for axially and/or angularly blocking securing means in one or both axial and/or angular directions.
Thereby, a determined and/or stable axial position of sealing means and the securing means with respect to each other may be achieved according to an embodiment.
According to an embodiment, a radial protrusion may be a, in particular block-or cylinder-formed, integral extension of the sealing means' body, in particular extending from its outer surface.
According to an embodiment, an additional or alternative radial recess may be deployed, in particular dependent on the geometry of the securing means, which in different embodiments may itself contain complementary protrusion(s) and/or recess(es).
According to an embodiment, the sealing means, in particular on its outer surface, comprises at least one axial locating protrusion and/or recess for axially blocking the securing means and at least one angular locating protrusion and/or recess for angularly blocking the securing means.
Thereby, a defined and/or stable axial and angular position of the sealing means and the securing means with respect to each other may be achieved according to an embodiment.
In various embodiments, axial and/or radial location protrusions may S provide the joint means with an "unlosable"-feature with respect to the securing means, which may thus be attached to the sealing means in a way that allows for both assembly and secure attachment.
According to an embodiment, the term "unlosable" does not refer to a 100% elimination of the possibility to detach sealing means and securing means from each other1 but rather refers to prevention of losing" the securing means in an assembly environment with skilled and non-misusing staff.
According to an embodiment, an axial locating protrusion is formed in a way that blocks, at least partially, one or both directions of an axial degree of freedom and may also block at least one other degree of freedom or a single direction of this other degree of freedom.
According to an embodiment, an angular locating protrusion is formed in a way that blocks, at least partially, one or both directions of an angular degree of freedom and may also block at least one other degree of freedom or a single direction of this other degree of freedom.
According to an embodiment, the securing means comprises a spring clamp, in particular may be made from a metal material.
Thus, a more secure, flexible and/or easier to assemble joining means may be achieved in one embodiment.
According to an aspect of the invention, a fluid joint assembly comprises at least one joint means according to the previously described aspect or one of its embodiments. One of the piping elements may be formed as a fluid communication interface, in particular may be formed as a metallic spigot, in particular of an exhaust gas line.
Thus, according to an embodiment, the fluid joint assembly can be adapted to various, in particular predefined, applications in a better, cheaper and/or quicker way.
According to an embodiment, at least one of the piping elements comprises a joint protrusion for axially blocking the joining means in at least one axial direction.
Thereby, a defined and/or stable-for-lifetime axial position of the sealing means and the piping element with respect to each other may be achieved according to an embodiment.
According to an embodiment, the fluid joint assembly comprises a first piping element and at least a second, in particular also a third, piping element, wherein each of these piping elements is joined with the joint means, in particular received by one recess, in particular the inner or outer recess, of the sealing device. Thereby, according to an embodiment, more than two piping elements may be connected in a better way.
According to an embodiment, the first piping element extends into one of the inner and the outer recess portion of the sealing means, wherein the second piping element extends into the other of the inner and the outer recess portion of the sealing means.
This may allow for joining of the piping elements with an axial overlap and/or, in particular thus, better sealing, and may also allow for joining of piping elements having different joining diameters.
According to an embodiment, the first and/or the second piping element is, in particular selectively, compressed by the securing means. Thus, according to an embodiment, a reactive decompression force may be induced and/or may thereby allow for a more secure connection of sealing and securing means(s).
According to an embodiment, a selective compression may be a compression that is applied only to a, in particular predefined, area of the sealing means and/or that is adaptable with respect to the sealing means application areas and/or strength of applied forces.
According to an aspect, a motor vehicle comprises a fluid joint assembly according to one aspect or one of its embodiments described herein.
According to an aspect, a method for joining at least two piping elements of a fluid joint assembly according to the second aspect described or one of its embodiments comprises the steps of: -inserting -subsequently or in parallel -a first piping element into one of the inner and the outer recess of the sealing means and a second piping element into the other one of the inner and the outer recess of the sealing means; and -securing the securing means at an axial position of an axial overlap of the first and the second piping element.
Thereby, a joining means consuming less space may be provided according to an embodiment. This may allow for offering a joining means with improved sealing and/or less parts. Thus, a more secure, flexible and/or easier to assemble joining means may be achieved according to an embodiment.
According to an embodiment, in particular in a previous step, the securing means is positively locked and/or form fit blocked, with at least one radial protrusion of the sealing means, in particular determining the position and/or limiting the displacement of the securing means in at least one axial and/or angular direction.
Thereby, a defined and/or stable-for-lifetime axial and angular position of the sealing means and the securing means with respect to each other may be achieved according to an embodiment.
In various embodiments, axial and/or radial location protrusions may provide the joint means with an "unlosable"-feature with respect to the securing means, which may thus be attached to the sealing means in a way that allows for both assembly and secure attachment.
The above as well as further aspects, embodiments, features and advantages of the present invention will become more apparent from the following description of preferred embodiments of a sealing means with reference to the attached drawings, in which Fig. I schematically shows a sectional view of an embodiment of a fluid joint assembly comprising a sealing means and a securing means for overlapping connection of two piping elements; and Fig. 2 schematically shows a top view of another embodiment of a fluid joint assembly comprising a sealing means and a securing means for overlapping connection of two piping elements.
Fig. 1 schematically shows a sectional view of an embodiment of a fluid joint assembly I comprising a joint means 2 with a sealing means 3 and a securing means 8 for overlapping connection of two piping elements 10 and 12. The fluid joint assembly 1 is displayed in an assembled state of operation, wherein the sealing means 3 has been put onto / is positioned on the first piping element 10 with a surface of inner recess 4.
The first piping element 10 has a joint protrusion 11 at a predefined axial position, in particular within the extension of the axial overlaps, which serves as a stop for assembly of sealing means 3.
The first piping element 10 in this exemplary embodiment has a smaller diameter than the second piping element 12.
All references with respect to dimensions or directions in this description refer to the longitudinal axis L of the fluid joint assembly.
Second piping element 10 has been inserted in / is positioned in outer recess 5 of the sealing means 3, in particular up to the rear wall of the circular hollow forming outer recess 5 in this embodiment. In an assembled state of operation, both piping elements 10 and 12 axially overlap each other, each thereby applying additional sealing forces, in particular elastic deformation forces, to the connection of the other piping element 12 or 10 and the sealing means 3.
Different pre-assembly options are within the scope of this exemplary embodiment: the joint means 2, in particular with its sealing means 3, may be pre-assembled to the first piping element 10 at the inner recess 4, or to the second piping element 12 at the outer recess 5.
As the inner recess 4 extends all the way through the sealing means, fluid may freely flow through the joint means. According to an embodiment, edges, corners and/or surfaces of a piping element or sealing means may be formed and/or adapted to each other in a way allowing for laminar fluid flow along their surfaces.
The securing means 8 comprises, in particular is formed as, a spring clamp, which is positioned on the outer surface 13 of the sealing means 3 at an axial position of the overlap of the joined piping elements. This axial position of the securing means 8 is secured by axial locating protrusion 6 of the sealing means 3.
The securing means 8 is tightened to a predefined extent. Thereby, it applies pressure forces directly onto the outer surface 13 of the sealing means 3, and indirectly onto the connections of each of the piping elements 10, 12 with the sealing means 3, thus improving the sealing effect of the joint means 2.
Fig. 2 schematically shows a top view of another embodiment of a fluid joint assembly 1 comprising a sealing means 3 and a securing means 8 for overlapping connection of two piping elements 10 and 12.
Piping element 12 displays a widened joint ending diameter in this embodiment. This widened joint ending diameter is adapted to filling outer recess 5 of the sealing means 3. Embodiments with piping elements 10 and/or 12 adapted at their joint endings by a wider or closer diameter are also within the scope of the invention.
Sealing means 3 comprises an angular locating protrusion restricting movement of securing means 8 to an angular range that is predefined by the dimensions of nut 9 once assembled.
Whilst exemplary embodiments have been presented in the foregoing description, it should be apparent that a vast number of variants and modifications exist, It should also be appreciated that the exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration in any way. Rather, the foregoing summary and detailed description will provide those skilled in the art with a convenient road map for implementing at least one exemplary embodiment, it being understood that various changes may be made in the function and arrangement of elements descilbed in an exemplary embodiment without departing from the scope as set forth in the appended claims and their legal equivalents.
