专利说明:
[0001] The present invention relates to a system for the end-to-end connection of two tubes, the system comprising a clamping collar having a clamping band capable of being clamped around the abutting ends of the two tubes. [0002] More specifically, the invention relates to a clamping system of the aforementioned type, which can be pre-mounted at the end of the first tube, before the abutment of the latter with the second tube and the clamping of the band. A clamping system of this type is known from documents EP 1 451 498 and EP 2 598 785, in the particular case where the tubes have bearing surfaces and where the inner periphery of the collar delimits a recess receiving its surfaces. In the aforementioned patent documents, the clamping system comprises pre-assembly means for, in the unclamped state of the collar, to secure this collar with the first tube before coupling with the second tube. In a way, the collar is thus put on hold at the end of the first tube to facilitate its coupling with the second tube, then the tightening of the two coupled tubes. The clamping systems described in the aforementioned patent documents have a washer secured to the collar, and this washer has tabs or the like for pre-assembly of the assembly comprising the collar and the washer with the first tube. Systems of this type are satisfactory, but they require the use of a washer. This washer can have other functions than that of contributing to the pre-assembly, in particular by contributing to the sealing of the coupling of the two tubes once they are tight. However, in some systems, a simpler conformation sealing washer can be used, or the use of such a washer can be avoided, particularly if the conformation of the tubes itself promotes the watertightness of their seal. coupling or if the required sealing level is lower. The present invention aims at providing a system for connecting two tubes, comprising a clamping collar which can be pre-mounted at the end of the first tube, before its coupling 3025581 2 with the second tube, without making it essential to use a washer to ensure this pre-assembly. Thus, the invention relates to a system for the end-to-end connection of two tubes, the system comprising a clamping collar having a clamping band capable of being clamped around the abutting ends of the two tubes. According to the invention, the collar comprises a retaining tab, which has an attachment portion through which said retaining tab is fixed to the band of the collar and which extends substantially axially towards an attachment portion of said retaining tab. whereby said retaining tab is adapted to be attached to the first tube in the vicinity of the first end thereof. Thus, according to the invention, the system can be delivered with the retaining tab attached to the band of the collar and can be handled as a whole. For pre-assembly, it is sufficient to arrange the collar in front of the end of the first tube, orienting it so as to direct the attachment portion of the retaining tab towards this tube, to pass the band around the tube. end of the first tube, then attach the retaining tab to the first tube. Thus, the system is waiting at the end of the first tube, which can be handled as a whole with the collar attached thereto, to abut the second tube. In its general definition, the invention provides at least one retaining tab. Several retaining tabs may be provided, for example two or three retaining tabs distributed angularly in a regular manner, in order to promote accurate centering of the collar around the end of the first tube before it is tightened. However, as will be seen in the following, the presence of several retaining tabs is not essential for the invention and it is on the contrary advantageous to provide only one retaining tab. The retaining tab may be semi-rigid, i.e., on the one hand, it has sufficient rigidity to, when attached to the first tube, hold the band of the collar in the desired position at the end of the first tube, in particular a position in which the axis of the collar is substantially aligned with that of the first tube and in which an annular space is delimited between the inner periphery of the strip and the 302 5 5 8 1 3 outer periphery of the collar. On the other hand, the retaining tab can be bent during tightening, to accompany the reduction in diameter of the collar that occurs during tightening, and remained attached to the band of the collar while remaining attached to the first tube. [0003] For example, the band of the collar is made of metal, in particular of stainless steel, of austenic or ferritic type and the tab is made of the same material and has a thickness substantially equal to that of the band. Optionally, the inner periphery of the collar has a recess capable of receiving a radial projection formed at the end of the first tube. In particular, the radial projection is annular and covers the entire circumference of the first tube so that the precise positioning of the retaining tab, considered angularly, does not have any particular importance, which facilitates the manufacture and the 15 mounting. For example, the radial projection may take the form of a bearing surface similar to those described in EP 1 451 498 and EP 2 598 785, projecting from the cylindrical outer surface of the first tube. Optionally, the attachment portion of the retaining tab extends at a distance from the axis of the collar that is less than or equal to the inner diameter of said web in the untightened state. The internal diameter of the strip in the unsealed state is defined so that the strip can be threaded onto the end of the first tube, without the radial projection of the first tube is an obstacle to this threading. In particular, the internal diameter of the strip is at least equal to the diametrical dimension of the first tube defined by its radial projection. In this case, once the collar is attached to the first tube by the attachment portion of the retaining tab, and because the distance from the axis of the collar (i.e. the axis defined by the the collar strip) is less than or equal to the internal diameter of said strip in the untightened state, the retaining tab naturally holds the band of the collar around the end of the first tube, without this strip being obstruct the coupling of the tubes. When placing the collar around the first tube, the attachment portion of the tab may be bent outward to pass the obstacle formed by the radial projection of the first tube, or, particularly when Only one retaining tab is present, the collar can be inclined to move the attachment portion of the tab relative to the axis of the first tube and thereby allow this attachment portion to pass the radial projection, then be straightened to align its axis with that of the first tube and then attach the attachment portion of the retaining tab to the first tube. Optionally, the collar has two ends movable relative to each other for clamping the collar, and the retaining lug is substantially diametrically opposed to these ends. The retaining tab thus cooperates with a part of the collar remote from the means used for clamping the collar, and therefore does not interfere with these means. Optionally, the retaining tab has a corrugation 15 between its attachment portion and its attachment portion. As indicated above, the retaining tab can be flexed, in particular to accompany the reduction of the diameter of the collar due to the clamping of the band and possibly to pass the radial projection of the first tube. The aforesaid corrugation promotes this deflection by forming a kind of spring integrated in the retaining tab. Because of its hardening, this undulation plays indeed the role of an elastic return spring. This spring is sufficiently stiff so that, in the untightened state of the web, the retaining tab naturally holds the collar in the desired pre-assembly position, while imparting the desired flexibility to the retaining tab. Optionally, the corrugation is radially projecting. The orientation of the radially projecting corrugation favors the fact that the elastic return forces it provides are exerted in the direction going towards the axis of the collar. Furthermore, the radial projection height of the corrugation can be determined so that it remains overall in the radial size of the collar, thus avoiding excessive projection. [0004] Optionally, the corrugation is inclined with respect to a radial plane, so that, going towards the top of the corrugation, one moves away from the fixing portion. In this case, the corrugation can have a fairly large amplitude, while having a limited radial size. In addition, being oriented in the direction indicated, the undulation does not interfere with the installation of the collar around the end of the first tube. In addition, when the collar is clamped on the abutting tubes, its diameter decreases and the leg deforms to accompany this decrease in diameter. [0005] The inclination of the corrugation makes it possible to ensure that, during this deformation of the tab, its fixing portion, which carries the collar, moves essentially radially, remaining substantially in the axial section that it occupied at the pre-assembled state, before tightening the collar. Thus, the tab has little or no tendency to urge the collar out of its proper axial position with respect to the abutting ends of the tubes. Optionally, the attachment portion is formed at the free end of the retaining tab, opposite to its attachment portion. In particular, the attachment and attachment portions may be formed at opposite ends of the retaining tab. [0006] The securing portion of the retaining tab may be attached to the collar by any suitable means, in particular by at least one of the methods of attachment including welding, crimping, clinching, snapping or clipping. Optionally, the collar has two radially projecting ends and a threaded clamping rod cooperating with said ends to move them relative to each other and tighten the collar by screwing. The invention also relates to a connection assembly of two tubes, comprising a system for the end-to-end connection of two tubes according to the invention, and a first tube, to which is attached the attachment portion of the retaining tab and which is adapted to be abutted with a second tube, the band of the collar extending around the end of the first tube. This assembly comprises the system according to the invention and the first tube at the end of which this system is pre-mounted in a state in which the band of the collar, in the unsealed condition, extends around the end of the first tube. Optionally, the attachment portion of the retaining tab is attached to the first tube by welding. [0007] This welding can be carried out by any known means, in particular by partial melting of the attachment portion of the retaining tab. It may in particular be one or more welding points, the forces to which the welding is subjected being small. Optionally, the attachment portion of the retaining tab is attached to the first tube by an attachment collar. This attachment collar can be simple and inexpensive because it has the function of attaching the retaining tab to the first tube, without being subjected to demanding stresses, particularly mechanically or sealing. [0008] Optionally, in the unsealed condition, the band of the collar is spaced radially from the end of the first tube. Thus, an annular space is defined between the band of the collar and the end of the first tube, in which space the end of the second tube can be inserted for connection and coupling of the tubes. [0009] The invention will be better understood and its advantages will appear better on reading the detailed description which follows, of an embodiment shown by way of non-limiting example. - Figure 1 is a perspective view, showing the collar pre-mounted at the end of the first tube, before tightening the collar; FIG. 2 is a sectional view in plane II of FIG. 1, this plane being defined by the axis of the tube and by a diameter of this tube passing through the retaining tab; FIG. 2A shows a variant for fixing the retaining tab to the band of the collar, in zone IIA of FIG. 2; FIG. 3 is a diagrammatic end view along arrow III of FIG. 2; FIG. 4 is a view similar to FIG. 1, but showing the clamped collar and the first tube coupled to a second tube; and FIG. 5 is a sectional view in the plane V of FIG. 4, this plane being similar to the plane II of FIG. 1. First, FIGS. 1 and 2, which show a collar of FIG. pre-assembled at the end 12A of a first tube 12. In this case, the collar is generally of the same type as that described in EP 1 451 498 and EP 2 598 785. It must however be understood that the invention is not limited to this type of collar. Throughout the rest of the description, the elements that are directed towards the axis A of the tube 12 or which are the closest to this axis with respect to other elements described as "external", the elements "which are referred to as" internal ", will be termed" internal ". "In this case, the collar 10 comprises a strip 14 which has an inner periphery which delimits a recess 16 in which bearing surfaces, respectively 18 belonging to the first tube 12 and 18 'belonging to the second tube 12' (see Figure 5) can be inserted. This recess and these bearing surfaces have such shapes that the tightening of the band of the collar constrains the ends of the tubes to move towards one another. Thus, the band 14 preferably has a V-shaped section while the bearing surfaces 18 and 18 '20 have a diameter which increases gradually towards the free ends of the tubes which are opposite, and are for example of frustoconical shape. The strip 14 of the collar has ends 14A and 14B, respectively, which are substantially radially rectified so as to form support lugs. These tabs are pierced so as to allow the passage of the rod 24A of a screw 24 through these tabs. The head of the screw 24 is keyed relative to the support lug 14B, while a nut 26 is retained relative to the other lug 14A. In the figures, the head of the screw is not visible, but it can be analogous to that shown in EP 1 451 498 and EP 2 598 785. In the present case, a wedging washer 26A is interposed between the support lug 14A and the nut 26, this washer having a notch the wedge relative to the tip of the V formed by the strip 14 to prevent it from rotating relative to it during the rotation of the screw. [0010] 302 5 5 8 1 8 Referring to Figure 5, it can be noted that the end 12'A of the second tube 12 'is a female end, its inner periphery having a flare. In contrast, the end 12A of the first tube 12 is a male end which, beyond the bearing surface 18, has an outer periphery 23 whose diameter decreases towards the free end. The end portion 12A thus formed can thus be inserted, substantially with complementary shape, inside the flare 17 formed at the end of the tube 12 '. This conformation, possibly associated with a washer interposed between the outer periphery 23 of the free end of the first tube and the inner periphery of the flare 17 of the second tube, can seal the connection between the two tubes, when the clamping system is tight. Such a washer may not be necessary, for example by choosing for the two tubes a material which allows slight deformation of the contacting surfaces under the effect of clamping, thus ensuring the required sealing, especially when the level of required sealing is not extremely high. The clamping collar 10 comprises a retaining tab 30 which, in the pre-assembled state of the collar, is fixed to the first tube 12. This tab 30 has a fixing portion 32 by which it is fixed to the band of the collar and an attachment portion 34, by which it is fixed to the tube 12. In this case, the fixing portion 32 has a hook shape whose free end is directed towards the axis A. Axial sectional view, this fixing portion has in fact substantially a V shape (seen in axial section), adapted to receive in its hollow the V-shaped band of the collar. It is further noted that the fixing portion 32 is in this case formed at the free end of the retaining tab, opposite its attachment portion 34. The tab 30 is generally oriented substantially axially from its portion of fixation and up to its attachment portion, and extends rearwardly of the collar, i.e. in the direction away from the tube 12 of the end 12A thereof. latest. In the free state, that is to say before the pre-assembly of the collar 10 on the tube 12, or in the pre-assembled state, the attachment portion 34 of the retaining tab 30 extends at a distance D1 from the axis of the collar (coincides with the axis A of the tube 12) which is less than or equal to the internal diameter D2 of the band of the collar (which inner diameter then being of course measured in the loose state of the collar). The attachment portion 32 of the retaining tab 30 may be attached to the tape 14 by any suitable means. Thus, it can be welded to the strip and two weld points 32 ', respectively located on each of the sections of the V, have been identified in FIG. 2. As shown in FIG. 2A, another method of attachment such as clinching or crimping, is also possible. Thus, in FIG. 2A, it can be seen that the fixing portion 32 of the tab 30 has two notches 32 ", respectively on each of the branches of the V, in which the material of the band 14 of the collar is pushed back to form projections 14 "that penetrate into these notches. With the above-mentioned V-shape for the section of the strip 14 and for the fixing portion 32 of the retaining tab 30, it is advantageous to provide an attachment point on each branch of the V. The attachment could also, for example , the hooks 32 "being replaced by small hooks which penetrate into notches made in place of the protrusions 14" or vice versa, or else by clipping, for example by means of staples or reported clips, not shown. In general, many methods of attachment are possible, the attachment between the retaining tab and the band of the collar is not, in principle, subjected to high stresses. [0011] The entire collar, including the band and the retaining tab, is handled as a unit and can be delivered assembled. By the attachment portion 34 of the retaining tab, the collar can be attached to the first tube 12 in a pre-assembled situation. It is noted in this case that the attachment portion 34 is axially oriented, located opposite the fixing portion 32, and fixed against the outer periphery of the tube 12. In particular, the attachment portion of the retaining tab 30 may be attached to the first tube 12 by a weld, comprising one or more solder points 34 '. [0012] However, other ways of attaching the attachment portion to the tube could be considered. For example, as shown in phantom, the fastening portion 34 may be integral with a fastener collar 40, which is itself attached around the tube 12. In particular, it may be a necklace of the type having two ends that hang on one another. Thus, this collar is initially opened to be passed around the tube, then closed and tight on this tube. This is for example a collar of the type described by the European patent document EP 0 003 192. The attachment portion 34 of the retaining tab can be fixed to this collar by any suitable means, in particular by welding, clipping, crimping or clinching. In the case where a fastening collar 40 is used, the assembly constituted by the clamping collar 10, comprising the retaining tab 30, and the fastening collar 40, can be delivered as a whole and pre-assembled to 15 The end of the tube 12. The retaining tab 30 has a corrugation 36 which is located between its attachment portion 34 and its fastening portion 32. This corrugation is radially projecting outside the first tube 12. Furthermore, it can be seen that the corrugation 36 is inclined relative to a radial plane P (see FIG. 2), so that going towards the apex 36S of the corrugation, one moves away from the fixing portion 32 In this case, the angle of inclination a is, in the unstressed state of the collar, of the order of 30 to 60 degrees. This angle is measured between the plane P and a median plane M of the undulation passing through its apex 36S. The corrugation extends over the entire width of the retaining tab, this width being measured perpendicular to the plane of FIG. 2, and thus forms a wave of the retaining tab. The retaining tab is formed in a strip, in particular a strip of metal material, folded and suitably screwed. With particular attention to FIGS. 2 and 4, it can be seen that, in both the unpressed and the clamped state, the corrugation is generally included in the radial size of the clamping system. since the peak 36S of the corrugation does not exceed substantially radially outwardly relative to the apex 32S of the hook formed at the fastening portion 32. [0013] In the embodiment shown, only one retaining tab 30 is sufficient to retain the collar in the pre-assembled state at the first end 12A of the tube 12. Referring to FIGS. 2 and 3, FIG. it can be seen that, in the pre-assembled state of the collar 10 at the end 12A of the tube 12, an annular space E is formed between the outer periphery of the tube 12 and the inner periphery of the band 14 of the collar. It can also be seen in FIG. 3 that, in the pre-assembled state, the collar is substantially centered with respect to the tube, the axis of the collar being in this figure coinciding with the axis A of the tube. [0014] Thus, the annular space E allows the insertion of the end 12'A of the second tube 12 '(see FIGS. 4 and 5) under the band 14 of the collar and the coupling of the two tubes. Thus, the retaining tab 30 is rigid enough to carry the cantilevered collar strip and maintain its correct position relative to the first tube 12. Furthermore, the retaining tab 30 may be flexed elastically for, on the one hand, possibly facilitate the pre-assembly of the collar on the first tube and, on the other hand, allow the tab to accompany the reduction of the diameter of the collar during the clamping of the latter. The corrugation 36 promotes this elastic flexibility. FIG. 2 shows that the undulation is open, that is to say that its two legs 36 'and 36 "which extend on either side between its vertex 36S and, respectively, the portion 32 of the retaining tab 30 and its attachment portion 34 to the first tube, however, in Figure 5, we see that the two legs 36 'and 36 "are close together. [0015] As previously indicated, the retaining tab may be made of the same material as the collar band, or a material having generally the same mechanical properties. This is in particular a metal such as steel which, depending on the application, may be a stainless steel. For example, when the invention is applied to the exhaust tubes of vehicle engines, it may be preferred to select stainless steel. In Figure 3, it is noted that the retaining tab covers an angular sector [3 of a few degrees, for example of the order of 2 ° to 10 °. In many cases, if the collar has a diameter of the order of 60 to 100 mm (as is for example the case 3025581 12 when it is used to butt two exhaust tubes of a vehicle engine), the retaining tab may have a width (measured according to the circumference of the collar) is of the order of 10 to 20 mm. The retaining tab may have a thickness similar to that of the band of the collar. In particular, it may have a thickness of the order of 1 to 1.5 mm. Once the collar is placed on hold, that is to say in a pre-assembly situation, at the end 12A of the first tube 12, it can be handled as a whole with this first tube. To assemble the first tube 12 with the second tube 12 ', the latter is brought to the end 12A of the first tube by inserting its end 12'A in the aforementioned annular space E, then clamp the collar in a conventional manner. In this case, the clamping means of the collar comprises the aforementioned screw which, when the nut is screwed onto the threaded rod of the screw, reduces the space between the support lugs 14A and 14B. Other tightening means 15 could of course be envisaged, in particular hooking or pinching.
