Description
- The invention relates to the attachment of a module, particularly an electronic module, such as a pressure sensor, to a tyre wall. More precisely it relates to a support and an insert for the attachment of such a module. It also relates to a tyre fitted with such an attachment support.
- For safety purposes, an increasing number of motor vehicles have monitoring systems comprising electronic modules and/or sensors mounted on each of the wheels of the vehicle, dedicated to measuring parameters such as pressure or temperature of the tyres of the wheels and designed to inform the driver of any abnormal change in the measured parameter.
- When an electronic device is used, it is preferable not to attach it directly to the tyre because that might disrupt the mechanical behaviour of the tyre when running, particularly when it deforms. Moreover it might mechanically stress the module too much and possibly damage it.
- Document EP 1 385 710 describes a device for attaching an electronic monitoring module to a tyre. This device comprises a plurality of patches or supports made of a rubbery mixture provided with rigid inserts designed to receive a screw. The electronic monitoring module designed to be attached by screwing is provided with pierced side lugs through which the screws are placed. This device is complex, costly to produce and not very reliable, mainly because it is too rigidly attached.
- Document U.S. Pat. No. 7,009,506 describes a system for attaching an electronic module comprising a patch presented according to various embodiments allowing removable attachments. According to one embodiment, the patch comprises a casing or insert provided with a spherical cavity that is partially open for the insertion of the module. Such a cavity imposes a very particular shape on the electronic module. Moreover, retention only by clamping may turn out to be insufficient in the event of great stress, as is often the case when running. According to another embodiment, the insert comprises a threaded internal portion. In these various embodiments, the electronic module is either entirely or to a very great degree retained in the insert. This requires an insert of large dimension. This gives rise mainly to a very high mechanical stress on the module which sustains all the stresses to which the patch is subjected. Because of the severe running conditions that tyres have to withstand, this type of attachment is too restrictive for the modules of recent technologies which aim to be light, compact and not subjected to mechanical stresses that are too great.
- The main object of the invention is to propose a method of attachment that allows better endurance of the assembly to the surface of a tyre. A further object is to propose a method of attachment allowing the electronic module to be easily and quickly installed and removed either for maintenance or replacement.
- For this purpose, the subject of the invention is a support for attaching a module to a wall of a tyre, comprising a substantially flexible body of substantially elongate shape, the body comprising at least one connecting surface capable of being placed substantially permanently against a wall of a tyre, a second, free surface opposite to the connecting surface and at least one substantially cylindrical housing, with its axis at right angles to the second, free surface of the body and open on this second, free surface, characterized in that the housing comprises a first substantially cylindrical portion extended by a chamber of substantially cylindrical shape and coaxial with the first portion and having a diameter greater than the diameter of the first portion of the housing.
- The essential feature of this attachment support is that it comprises at least one housing for attaching an insert designed to interact with an assembly element for attaching an electronic module. The insert has a geometry that is identical or similar to that of the studs designed to enhance tyre grip on snowy or icy surfaces.
- These studs are usually attached by being inserted into housings arranged for this purpose in the tread of the tyres. The shape of the housings and of the studs is adapted to provide an excellent durability over time of the studs in their housings.
- The supports and the inserts of the present invention therefore have the advantage of being able to be very easily assembled by insertion with very ordinary tools and of providing an excellent durability over time of the electronic modules thus attached.
- Moreover such an attachment support makes it possible to produce a very good decoupling of the stresses usually encountered between the tyre wall and the support, which are flexible, and the module, which is more rigid. It moreover allows the modules to be reused.
- According to one advantageous embodiment, the attachment support consists mainly of rubbery materials and the connecting surface comprises an adhesive.
- According to another advantageous feature, the support comprises a peripheral edge delimited by a top surface, the connecting surface, and a surface of a junction between the top surface and the connecting surface, which surfaces converge at the junction at an angle (a) of between 9 and 15 degrees, and more particularly between 10 and 12 degrees.
- The angle of the borders or peripheral edges of the support is a sensitive parameter that should be taken into consideration so that the attachment of the support to the tyre is durable. Specifically, if this angle is less than 9 degrees, folds may appear on the borders of the support because it is difficult to flatten these peripheral edges correctly. This situation is called “scalloping”. If this angle is greater than 15 degrees, the peripheral edges of the support are too rigid. It then creates excessive stresses on the tyre wall, which may cause cracks or detachments of the support when running.
- The invention also relates to a tyre comprising a support as explained above.
- In this tyre, the modulus of elongation at 10% of the rubbery mixture of the connecting surface of the support is preferably at most equal to the modulus of elongation at 10% of the portion of wall of the tyre to which the support is attached.
- The support may also comprise a layer of connecting mixture placed on the connecting surface without overlapping at right angles to the peripheral edge of the support. In such a variant, after the support has been manufactured by moulding, followed by curing, a layer of uncured connecting mixture is then placed on the connecting surface in order to provide the connection between the surface of the tyre and the connecting surface of the support. The thickness of this layer of connecting mixture is of the order of 0.3 mm. The support and layer of connecting mixture assembly is then cut out for example with a die. The cut-out surface of the connecting mixture must be exactly in line with the cut-out surface of the edging of the support. This makes it possible, after assembly to the tyre surface, to avoid having a layer of connecting mixture that protrudes from the support. Such a protrusion could cause a reduction in the service life of the assembly by oxidation of the connecting mixture that protrudes. The presence of the edging increases the margin of tolerance of the operation for cutting out the support including the connecting mixture. The risk of biting into the inclined portion of the top surface becomes practically zero.
- Another subject of the invention is an attachment insert interacting with the above support, comprising an elongate cylindrical body surmounted by an attachment head, of substantially cylindrical shape and with a diameter greater than the diameter of the cylindrical body, the insert being suitable for being mounted by insertion into a housing of the said support provided for this purpose.
- The attachment insert advantageously comprises, at the opposite end from the attachment head, a cylindrical opening designed to interact with an assembly element for attaching a module, in particular an electronic module.
- The assembly element may interact with the insert by screwing, clipping, bonding, force-fitting, magnetism or coupling.
- According to an advantageous variant, the axial cylindrical opening is provided with an axial internal thread and the assembly element is a screw.
- Preferably, the ratio between the external diameter of the attachment head Φ and the maximum external diameter of the cylindrical body of the insert φ is between 1.1 and 1.3.
- The cylindrical body of the insert may also comprise a zone of lesser diameter adjacent to the attachment head.
- A further subject of the invention is an assembly for attaching a module comprising an attachment support and an insert as described.
- The invention will be better understood on reading the following description given only as an example and referring to the appended drawings, in which:
-

FIG. 6 illustrates an electronic module placed against a wall of a tyre by means of a support and an insert, according to aspects of the invention; -
FIG. 7 shows a view in section of an enlargement of a first embodiment of a peripheral edge of a support; -
FIGS. 8 , 9 and 10 are views in section of enlargements of three embodiments of a peripheral edge of a support with a layer of connecting gum. - These figures illustrate embodiments of an electronic module-support assembly with attachment by screwing, but equally apply to the other claimed embodiments. They are given for purely illustrative purposes and are not limiting.
- “Modulus of elasticity” of a gum or rubbery mixture means a secant modulus of extension at 10% of deformation and at ambient or specified temperature, the measurement is taken after a first accommodation cycle up to 10% of deformation:
-
-
- in which ε10 is equal to 0.1; where
- E10: secant modulus of extension at 10% of deformation; F10: extension force at 10% of extension; S0: initial section of the test piece; S: section of the test piece at the extension deformation ε, in the case of rubbery material, it is known that:
-
-
- and ε10: extension deformation at 10%.
- The figures illustrate examples of support and attachment inserts suitable for attaching electronic modules or other modules to the surface of tyres of all types and particularly aircraft tyres. The
support 10 is designed to be fitted to atyre 100 in order to attach anelectronic module 60 to the inside of the cavity of the latter, more particularly against aninternal wall 101 of the tyre. The attached module can be of various types, depending on the requirements and the planned type of use. As an example, it is possible to cite electronic modules such as: pressure sensor, temperature sensor, vibration sensor, etc., preferably all furnished with means for communicating with a centralized device provided on the vehicle. -
FIG. 1 shows a view in perspective of anattachment support 10 according to the invention. It comprises abody 11 that is substantially flat and elongate. Provided on a first face is a connectingsurface 26 that is substantially flat and uniform, designed to interact with the internal wall of the tyre for an attachment that is preferably permanent. To make the assembly easier to place and attach, this surface can be provided with an adhesive suitable for rubbery materials. According to another embodiment, the surface may also be provided with a layer of connectingmixture 44, as described below. Thebody 11 also comprises a second,free surface 28, opposite to thesurface 26. - The
support 10 comprises at least onehousing 20. In the example ofFIG. 1 , fourhousings 20 are provided so as to correctly distribute the retaining force for an electronic module of rectangular shape corresponding substantially to the periphery of the support. The number, arrangement, and spacing provided between the housings vary depending on the embodiments as a function of several parameters, such as the type and number ofassembly elements 50 used, the surface area and the shape of the module to be attached, the type of use planned for the tyres (aircraft, passenger vehicle, agricultural vehicle or lorry, industrial vehicle, etc.), the intended period of attachment, etc. - The
housings 20 are advantageously provided in portions of thebody 11 in which the thickness is greater than the rest of thesupport 10. Between these portions,passageways 12 of reduced thickness make it possible to reduce the weight of thesupport 10 and to adjust the desired level of flexibility. - As illustrated in
FIGS. 1 , 7 and 8, 9 and 10, thesupport 10 comprises aperipheral edge 40 delimited by the line ofjunction 41 between the connectingsurface 26 and atop surface 42. For manufacturing reasons and in particular to make aeration easier during moulding, it is possible for the line ofjunction 41 to be not of zero thickness but to be thin, of the order of 0.1 to 0.2 mm. In this case it is called the surface ofjunction 41. The twosurfaces junction 41 and between them, close to theline 41, form an angle alpha (α) of between 9 and 15 degrees and preferably between 10 and 12 degrees. - Preferably, the angle alpha (α) between the two
surfaces peripheral edge 40 extending to a distance d of approximately 7 mm from the line ofjunction 41. -
FIGS. 8 , 9, and 10 show in section enlargements of three embodiments of theperipheral edge 40. In these three figures a layer of connectingmixture 44 is shown. InFIG. 8 , the twosurfaces junction 41, that is to say a surface ofjunction 41 of zero thickness. - In
FIG. 9 , theperipheral edge 40 is delimited by a surface ofjunction 41 at right angles to thesurface 26 and with a thickness a of the order of 0.1 to 0.2 mm. - In
FIG. 10 , theperipheral edge 40 comprises an edging 47 that has a rectangular section and that extends over a distance of between 0 (as inFIG. 8 ) and approximately 1.5 mm. The presence of this edging 47 and of the surface ofjunction 41 make it easier to aerate the moulds for manufacturing the supports. It is also possible to use vents for example in other locations and retain a geometry as illustrated inFIG. 8 . - Still in
FIGS. 8 , 9, and 10, note the presence of alayer 44 of connecting mixture, of thickness b of approximately 0.3 mm, placed against the connectingsurface 26. This optional layer of connecting mixture ends at the peripheral edge without protruding from the edging or the surface or the line of junction. -
FIG. 2 shows a view in section of a portion of the attachment support ofFIG. 1 , in particular a portion in which ahousing 20 is provided. According to this example, thehousing 20 comprises an opening on the side opposite to the connectingsurface 26 namely the side of thefree surface 28. Thehousing 20 comprises a first substantiallycylindrical portion 22 with an axis at right angles to thefree surface 28 and which extends in thesupport 10 towards the connectingsurface 26 via achamber 21 of substantially cylindrical shape that is coaxial with thefirst portion 22 and has a diameter greater than the diameter of thefirst portion 22 of thehousing 20. - This
housing 20 is designed to receive anattachment insert FIGS. 3 and 4 . Theinsert 30 comprises an elongatecylindrical body 31 surmounted by an attachment head or lockingcollar 32. The function of thisattachment head 32 is to lock theinsert 30 in position when it has been forced into ahousing 20 of asupport 10. Theattachment head 32 has a diameter Φ greater than the diameter φ of the adjacentcylindrical body 31, in order to obtain this retention effect by clamping when the insert is in position in the corresponding housing of the support. The ratio Φ/φ is preferably between 1.1 and 1.3. - The
cylindrical body 31 comprises acylindrical bore 34 open on the side opposite to theattachment head 32. This bore 34 is designed to interact with an assembly element for the attachment of the electronic module. - The
insert 30 can be made of the same materials as a grip stud such as a metal like steel or aluminium; it may also be made wholly or partly of plastic. -
FIG. 4 shows a second embodiment of theinsert 35. Thisinsert 35 differs in two respects from theprevious one 30. The substantiallycylindrical body 31 comprises athinner zone 36, with a smaller diameter than that of the rest of thecylindrical body 31, placed adjacent to theattachment head 32. This thinning enhances the effectiveness of the anchoring of theinsert 35 in ahousing 20. It also comprises a foot 33 placed on the side opposite to the attachment head and arranged as a thinner extension of thebody 11. Thebody 11 of thesupport 10 and theinsert 35 are configured so that the foot 33 protrudes from thebody 11 in order to obtain a bearing surface for theelectronic module 60, as illustrated inFIG. 5 . This arrangement makes it possible to space themodule 60 from thebody 11 by at least 1 mm. - It should be noted that the same spacing between the electronic module and the
free surface 28 of the support can be easily obtained by using an attachment insert as illustrated inFIG. 3 . It is sufficient to add a washer of desired thickness between the head of the assembly element and the insert. - In the example of
FIG. 5 , theinsert 35 has, as illustrated inFIG. 4 , a non-constant diameter between the foot 33 and thehead 32, but the portion adjacent to thehead 32 has a diameter that is recessed relative to thehead 32. The external diameter of theinsert 35 and the internal diameter of thecorresponding housing 20 are designed so as to obtain a tight fit. In this way a good hold is obtained despite the many mechanical stresses that the assembly must sustain.FIG. 4 shows abottleneck portion 36, which provides an effective hold of theinsert 35 despite the considerable axial forces which tend to expel the latter from thesupport 10 in use. - The
inserts assembly element 50, moreover interacting with theelectronic module 60 that has to be attached. In this embodiment, as illustrated inFIG. 5 , theassembly elements 50 are screws. The screws are provided so as to hold themodule 60 resting against the feet 33 of the inserts 35: the screw head is resting on the outside of themodule 60, the stem of the screw being held in thecylindrical opening 34 by aninternal thread 37. -
FIG. 6 shows an electronic module attached to theinternal wall 101 of atyre 100 by means of a support and of inserts according to the invention. It shows theperipheral edge 40 of thesupport 10 to which themodule 60 is attached. In this example, the assembly is positioned in the bottom portion of the sidewall of thetyre 100. This position, and the orientation of the assembly, may vary depending on the applications. - The supports 10 are preferably made of a single rubbery mixture. This makes them easier to produce. This mixture has a modulus of elongation at 10% at most equal to that of the
tyre wall 101 against which thesupport 10 is intended to be attached. In other words, thesupport 10 is more flexible than the adjacent mixture of thetyre 100. As an example, for a modulus of elongation at 10% of the mixture inside thetyre 100 equal to 2.2 MPa at 65° C., the rubbery mixture of thesupport 10 will be chosen to be a mixture of which the modulus of elongation is at most equal to 2.2 MPa at 65° C. For good endurance of the assembly, the modulus of the mixture used should comply with this limit value throughout the temperature range of thetyre 100 when running, typically between 0 and 80 degrees Celsius. The mixture may be natural rubber-based and/or synthetic rubber-based. - It is naturally also possible for the
supports 10 to consist of several layers of rubbery mixtures. In this case, the rubbery mixture of the connectingsurface 26 has a modulus at most equal to that of the mixture of thetyre wall 101. - An aircraft tyre was fitted with an electronic module by means of a support with four housings as illustrated in
FIG. 1 and of attachment inserts as illustrated inFIG. 4 . The assembly elements were screws. This tyre underwent the usual homologation tests without the electronic module being torn off or damaged. - Finally, the invention is not limited to the examples previously described. It is possible, for example, to provide a plurality of geometries for the support and the inserts. Moreover, the number of inserts and of assembly elements may also vary depending on the embodiments, in particular as a function of the shape and dimensions of the electronic module.
