Description

Assembly of a first article and a second rubber article detachably connected to the first article
The invention relates to an assembly of a first article and a second rubber article detachably connected to the first article. The invention in particular relates to an assembly in the form of a vehicle spoiler comprising an adapter plate as first article and an airflow guiding element as second rubber article. The invention further relates to a method for manufacturing the assembly.
Some applications require a temporary connection between articles, one of which is a rubber material. Flexible bodywork elements of vehicles are an example, such as the flexible spoiler with a movable airflow guiding element disclosed in US 7,055,891. The vehicle spoiler disclosed comprises an adapter plate to which one edge of an airflow guiding element is connected. The airflow guiding element can be deployed and moved back to its basic position around the connection with the adapted plate by an actuating member between a retracted inoperative position in which the airflow guiding element lies against the adapted plate, and an extended operative position in which the airflowconducting element is deployed to form an extension of the bumper of the vehicle.
It is important to be able to swiftly bring the airflow-guiding element from the folded-out operative position to the folded-in retracted position, in which it is detachably connected to the adapter plate, and to keep it in this position for the intended time. Alternatively, it is also important to be able to swiftly bring the airflow-guiding element from the folded-in operative position to the folded-out retracted position.
The present invention therefore has for its object to provide an assembly of a first article and a second rubber article detachably connected thereto, in which assembly the temporary connection is swiftly made but also disrupted, yet provides adequate connecting force.
According to the invention, these contradicting requirements are provided by an assembly, wherein a locking part of the second rubber article is movable from an unlocked position in which the locking part is positioned at a distance from the first article to a locked position in which a surface of the locking part lies against a surface of the first article with a locking force, wherein the first article comprises a magnetic part with a longitudinal direction that extends parallel to the surface of the first article, which magnetic part in the longitudinal direction thereof comprises a number of subsequent sections with alternating polarity, and wherein the locking part of the second rubber article comprises a ferromagnetic part that aligns with the magnetic part in the locked position.
As well known in the branch the highest attraction force will be achieved if two permanent magnets are perfectly aligned. However if there is a mismatch in alignment of only 10% of the total width of the permanent magnet, the attraction force drops down until almost 0. Furthermore, the higher the stored energy B.H,n:,v according to DIN IEC 60404-8-1 is in a magnet, the higher the attraction force is, which the magnet can apply. However the Curie temperature is lower. It means that application of permanent magnets in rubber molded articles is limited to those magnets with a Curie temperature which is much higher than the vulcanization temperature of the rubber. The present invention provides a solution of the above mentioned problems.
The permanently magnetic part in the first article and the ferromagnetic part in the second rubber article cooperate together to advantage in a number of ways. Since, according to the invention, the magnetic part in the longitudinal direction thereof comprises a number of subsequent sections with alternating polarity, a strong magnetic field is created in which the magnetic field lines are closed in the longitudinal direction of the magnetic part, apart from being closed in a transverse direction perpendicular to the length direction of the magnetic part. The magnetic flux will be more equal in the surface parallel to both parts compared with a magnet with only 1 polarity section. Consequently, the total attraction force is higher and the susceptibility for a misalignment of the magnetic and the ferromagnetic parts is reduced.
The magnetic force of attraction usually decreases with the distance between the first article surface and the locking part of the second rubber article, and a minimum distance exists for which the magnetic force of attraction is negligible. The assembly of the invention allows to admit a larger distance, without having to provide the second rubber article with a permanent magnet, which would provide an increased magnetic attraction force between the articles.
Having to provide the second rubber article with a permanent magnet would entail the use of a vulcanizing mould made from a non-magnetic material. This goes at the expense of wear-resistance and cost. Further, two permanent magnets provided in the articles need to be exactly aligned in order to cooperate in a proper fashion. The level of dimensional tolerance needed is not easily achieved when moulding and vulcanizing a rubber article.
Suitable ferromagnetic parts are made of ferromagnetic materials, which include iron, nickel, cobalt and their alloys, rare earth metal compounds, and naturally-occurring minerals such as lodestone for instance, without being limited thereto.
According to another embodiment of the invention, an assembly is provided wherein the ferromagnetic part of the second rubber article has a longitudinal direction that extends parallel to the surface of the locking part.
In a particularly preferred embodiment, the longitudinal direction of the magnetic part in the first article extends parallel to a longitudinal direction of the first article, and/or the longitudinal direction of the ferromagnetic part in the second article extends parallel to a longitudinal direction of the second article.
In another embodiment of the assembly according to the invention, the magnetic part of the first article has an energy product ΒΗ^χ according to DIN IEC 60404-8-1 of larger than 200 kJ/m3 at 20°C, more preferably of larger than 260 kJ/m3 at 20°C. Suitable magnetic parts comprise anisotropic magnets, preferably rare earth magnets, such as neodymium (NdFeB) magnets and samarium-cobalt (SmCo) magnets. The person skilled in the art will have no difficulty in selecting a magnetic part exhibiting the properties as claimed in the present invention.
The number of subsequent sections with alternating polarity in the magnetic part may vary widely. A useful embodiment of the assembly according to the invention is characterized in that the number of subsequent sections with alternating polarity is at least 2 in the longitudinal directional. In yet another more preferred embodiment, the number of subsequent sections with alternating polarity is at least 5 in the longitudinal directional.
The detachable connection of the assembly in accordance with the invention has many advantages. One of these is that the connection can readily be disrupted by shear. An embodiment of the invention hereto provides an assembly that further comprises a fluid source that is adapted to bring a fluid under pressure between the surface of the locking part and the surface of the first article in the locked position in order to separate the surfaces and unlock the first article and the locking part of the second rubber article. A particularly useful embodiment in this context relates to an assembly wherein the fluid comprises air.
An assembly according to one embodiment of the invention has a fluid source comprising an inflatable bellows that partly extends between the surface of the locking part and the surface of the first article in the locked position.
The magnetic part(s) may be attached to the first article by any method known in the art. Mechanical, physical and/or chemical bonding methods may be envisaged. It is possible for instance to adhere a surface of a magnetic part to the first article by adhesive bonding and/or by welding.
In an embodiment according to the invention, the first article comprises cavities in which the magnetic part(s) are received. Preferably, the cavities extend through the wall thickness of the first article.
In yet another embodiment of the invention, an assembly is provided in which the magnetic part(s) are embedded in a polymer cover that is shaped such that it can be received into the cavities, preferably by clicking. The polymer cover may comprise any polymer but preferably comprises an organic polymer, selected from the group consisting of polyester, polyether, polyamide, polycarbonate, vinyl polymer, polyolefin, styrene polymer, thermoplastic vulcanisates and/or thermoplastic rubber, in particular thermoplastic polyurethane.
An additional advantage of the application of a polymer in which the permanent magnet is embedded is the protection against corrosion, since materials from which the permanent magnet are made are extremely corrosive. It enables the application of the invention in outdoor and wet environments. A strong connection in the locked position is reached for an embodiment of the assembly in which the total distance between the magnetic part and the corresponding aligned ferromagnetic part is less than 2 mm in the locked position. Even more preferred is an embodiment in which the total distance between the magnetic part and the corresponding aligned ferromagnetic part is less than 1.5 mm in the locked position. The named distance depends on the positioning of the magnetic part in the first article, and on the thickness of the polymer cover, for instance.
The invention may be useful in an number of instances. The assembly may for instance comprise the gangway connection between wagons of a train. In a particularly useful embodiment of the invention an assembly is provided in the form of a vehicle spoiler comprising an adapter plate as first article, an airflow guiding element as second rubber article, and an actuating member as fluid source, the actuating member being configured to move the airflow guiding element relative to a part of the vehicle to which it is attached between a retracted inoperative position and an extended operative position in which the airflow-conducting element forms an extension of the vehicle part.
The invention also relates to a method for manufacturing the assembly. The method comprises the steps of A) molding a first article, B) attaching the coated / covered magnetic part(s) to the first article; C) molding the second rubber article together with the ferromagnetic part(s)
In an embodiment of the method, step B) comprises providing cavities in the first article with the magnetic part(s).
In yet another embodiment of the method, the metallic part(s) are integrated with the second rubber article during molding of the article by positioning the metallic part(s) in a mold for the article, adding unvulcanized rubber polymer to the mold, and vulcanizing the rubber polymer at a temperature exceeding 150°C. The magnetism of the ferromagnetic parts comprised in the second rubber article is not or only slightly affected by the relatively high vulcanization temperatures.
The invention will now be explained in more detail with reference to the following figures without however being limited thereto. In the figures:
Figure 1A shows a schematic cross-section of a flexible spoiler, comprising an airflow guiding element in the retracted position and an actuating element detachably connected thereto by an embodiment of the method according to the invention;
Figure IB shows a schematic cross-section of a flexible spoiler, comprising an airflow guiding element in the extended operative position and an actuating element detachably connected thereto by an embodiment of the method according to the invention;
Figure 2 shows a schematic view in perspective of part of the mounting element to which the airflow guiding element is attached;
Figure 3 A shows a schematic view in perspective of a partly covered magnetic part of the mounting element, in accordance with an embodiment of the invention; and Figure 3B shows a schematic view in perspective of the magnetic part of figure 3A without its cover.
Figures 1A and IB more particularly show a flexible spoiler 1 for a vehicle, of which only the lower flexible part is shown. Spoiler 1 comprises a second rubber article in the form of an airflow guiding element 11, a first article in the form of a mounting member 12 for mounting spoiler 1 to the vehicle and an air source in the form of actuating element 13 which can move the airflow guiding element 11 between an inoperative position, shown in figure 1A, and an operative position, shown in figure IB. The actuating element 13 is at one end 13a thereof connected to the mounting member 12 or other part of the vehicle, and at the other end 13b to the underside of the airflow guiding element 11. The other end 13b defines a locking part 15 of the guiding element 11. In figures 1A and IB, a permanent connection between is shown between the airflow guiding element 11 and the actuating element 13. The connection comprises a top plate 16 that is connected to the airflow guiding element 11 and clamps the actuating element 13 against the airflow guiding element 11.
In accordance with the invention, the top plate 16 is part of the air flow guiding element 11 and comprises a ferromagnetic part 2.
The top part of the airflow guiding element 11 is connected to the mounting member 12, for instance by bonding, and the airflow guiding element 11 pivots around this connection when actuated. In the embodiment shown, the actuating member 13 takes the form of an inflatable bellows having as number of inflatable chambers and disposed on the rear side of spoiler 1. When inflatable bellows 13 is inflated, as shown in figure IB, the airflow guiding element 11 moves forward from the moved-in inoperative position into the moved-out operative position. To bring the airflow guiding element 11 back to its inoperative position, the locking part 15 of the airflow guiding element 11 needs to be moved from the unlocked position, corresponding to the operative position shown in figure 1 A, in which the locking part 13b is positioned at a distance from the mounting element 12 to a locked position in which a surface 3 of the locking part 15 (which includes the top plate 16) lies against a surface 4 of the mounting element 12 with a locking force. The attraction force is generated by a magnetic part 5 with a longitudinal direction 6 that extends parallel to the surface 4 of the mounting element 12, and parallel to the longitudinal direction 7 of the mounting element, which extends in a direction about perpendicular to the plane of figure 1A or IB.
Figure 2 shows a schematic view in perspective of (part of) a mounting element 12 to which the airflow guiding element 11 is one-sidedly attached. The mounting element is an elongated molded structure extending substantially in a longitudinal direction 7.
The mounting element 12 comprises a number of cavities 8 arranged along the longitudinal direction 7, each of which cavities 8 receives a magnetic part 9. The cavities 8 extend through the wall thickness of the molded mounting element 12.
In an embodiment shown in figure 3A, the magnetic parts 9 are embedded in a polymer cover 20 that is shaped such that it can be received in the cavities 8 by clicking. To this end, the polymer cover 20 is provided with protruding edges 21 around its circumference. In figure 3 A, part of the cover 20 has been removed in order for the magnetic part 9 to be visible.
Figure 3B finally illustrates that the magnetic parts 8 after positioning in the mounting element 12 extend with a longitudinal direction 80 substantially parallel to the surface 4 of the mounting element 12. The magnetic parts 8 are also aligned such that they extend with their longitudinal direction 80 substantially parallel to the longitudinal direction 7 of the mounting element 12. In accordance with the invention, the magnetic parts 8 in the longitudinal direction 80 comprise a number of subsequent sections 81, 82 with alternating polarity. In the example shown the sections 81 have a north pole polarity N, while sections 82 have a south pole polarity S. As a result, the concentration of effective magnetic field lines is high in the vicinity of each magnetic part 8.
