    Assembly for a clutch device, especially for a motor vehicle
    The present invention relates to an assembly for a clutch device, particularly for a motor vehicle.
    In a motor vehicle, a device is designed to couple in rotation a motor shaft, such as for example a crankshaft, and an input shaft of a gearbox.
    The clutch device usually comprises a cover in which is housed an annular diaphragm pivoting between an engaged position and a disengaged position so as to move a pressure plate. The diaphragm pivots about first and second circumferentially extending bearing regions respectively on either side of the diaphragm, respectively between the diaphragm and the cover and between the diaphragm and the pressure plate. The lid, the diaphragm and the pressure plate are integral in rotation.
    The annular diaphragm thus forms an articulated lever and has at its radially inner periphery radial fingers cooperating with a clutch abutment whose axial displacement causes the tilting of the diaphragm between its engaged and disengaged positions. The outer periphery of the diaphragm allows it to move the pressure plate. The clutch release is operated by the user using the clutch pedal.
    The pressure plate, urged by the diaphragm, is for clamping a friction disc on a reaction plate coaxial with the pressure plate and the friction disk.
    The friction disc is rotatably connected to the input shaft of the gearbox and the reaction plate is rotatably connected to the cover and a flywheel connected to the drive shaft. Thus, the clamping of a friction disc between the pressure and reaction plates allows the transmission of a torque between the motor shaft and the input shaft of the gearbox. The use of the clutch causes wear friction friction linings as well as counter-materials of the pressure plates and associated reaction. This results in a variation of the position of the pressure plate relative to the diaphragm and / or the associated reaction plate, generating a variation of the friction disk clamping force and / or a modification of the licking point and the stroke of the clutch stop. It is recalled that the licking point is the position from which a portion of the engine torque is transmitted to the shaft of the gearbox when closing the clutch.
    FIG. 1 represents the variation of the load F of the diaphragm measured at the abutment, that is to say the variation of the axial force to be exerted by the clutch abutment to actuate the diaphragm, along the axis of said abutment, as a function of the axial displacement D of the abutment, respectively for zero wear (CO curve), for wear equal to 50% of the maximum permissible wear (curve C1), and for the maximum permissible wear (curve C2).
    On each of said curves, the engaged position is represented by an abscissa or a displacement D respectively equal to DO, D1 and D2, the disengaged position being represented by an abscissa or a displacement D equal to D3.
    It can be seen that, for each of the curves, the load of the diaphragm measured at the stop increases progressively during the disengaging phase, until reaching a maximum load (for a displacement Dmax), before gradually decreasing to the disengaged position. . It is also noted that the maximum load of the diaphragm increases with wear.
    However, the load of the diaphragm measured at the stop is related to the force exerted by the user on the clutch pedal. In other words, the effort that a user must exert on the pedal to disengage will be all the more important that wear is important.
    To ensure the comfort of the user, it is necessary to limit to a certain value the effort to be applied on the pedal.
    In order to compensate for the wear, the document FR 2 847 626, in the name of the Applicant, proposes means of catching wear interposed between the pressure plate and the diaphragm. These wear-compensating means comprise a ring with circumferential ramps which cooperate with counter-ramps complementary to the pressure plate. The ramp ring also serves to support the diaphragm so that the rotation of the ring relative to the pressure plate causes the ramps to move relative to the counter-ramps and thus the axial displacement of the pressure plate. relative to the diaphragm, lid and reaction plate. The distance between the pressure plate and the associated reaction plate is thus varied in a way that offsets the wear.
    A toothed member is also fixed on the ramp ring and meshes with a worm mounted in a support, also called cassette, attached to the cover, the toothed member being at right of the worm.
    The worm is coupled in rotation with a ratchet wheel cooperating with a pawl fixed on the cover and actuated by the diaphragm.
    In this way, in case of wear and during successive actuations of the diaphragm, the pawl causes rotation of the ratchet wheel and the worm, the latter causing rotation of the ring carrying the ramps, by the intermediate of the toothed organ. This progressively increases the distance between the pressure plate and the cover and gradually decreases the distance between the pressure plate and the associated reaction plate, so as to compensate for wear.
    Such wear compensating means are relatively complex and expensive.
    In order to compensate for the influence of wear on the load of the diaphragm at the stop, it is also known to provide a support washer, mounted axially between the cover and the diaphragm, the support washer exerting an axial force opposing, in part, that exerted by the diaphragm, so as to reduce the maximum effort to exert on the clutch abutment.
    FIG. 2 is a diagram similar to that of FIG. 1, in which the variation of the load measured at the stop F 'as a function of the axial displacement D' of the abutment takes account of the force exerted by the assistance washer. . The corresponding curves are referenced C'O (zero wear), C'1 (wear at 50%) and C'2 (maximum wear).
    It is found that the assistance washer is defined so that the curves C'1 and C'2 each comprise a clipped portion E to reduce the maximum force F'max to provide at the stop in case of wear .
    The assistance washer thus reduces the effort to be exerted by the user on the clutch pedal, especially in case of wear of the friction disc. The use of such a washer assistance is particularly known from CN201410688114.
    However, it is found that, in the disengaged position of the diaphragm, the diaphragm comes off the assistance washer, so that the assistance washer is no longer stuck axially between the diaphragm and the cover but can move freely according to its axis. Such a free displacement of the assistance washer can generate noises, wear of the supports of the assistance washer, and cause premature damage to the assembly. The invention aims to remedy this drawback in a simple, effective and inexpensive way. For this purpose, it proposes an assembly for a clutch device, particularly for a motor vehicle, comprising a cover having an axis, a pressure plate movable relative to the cover along said axis and actuated by a diaphragm interposed axially between the cover and the pressure plate, the diaphragm being movable between the engaged position and a disengaged position, an elastically deformable assistance washer, interposed axially between the cover and the diaphragm and capable of exerting a variable axial force as a function of the position of the diaphragm, characterized in that, in the disengaged position of the diaphragm), the support washer is able to come axially in abutment on a fixed spacer relative to the cover so as to maintain said support washer bearing against the cover, said washer of assistance being not supported on the diaphragm, and in that, in the engaged position of the diaphragm, said ondelle assistance is supported on the diaphragm and is not supported on said spacer.
    The assistance washer is thus maintained in axial position between the diaphragm and the cover, in the engaged position, and between the spacer and the cover, in the disengaged position. The washer can not move freely along its axis, thus avoiding the phenomena of noise and premature damage. Support of the assistance washer on the surrounding parts, that is to say the lid, the diaphragm or the spacer, can be achieved directly or indirectly, that is to say via one or more separate rooms. The assembly may comprise at least three spacers distributed over the circumference of the cover, the support washer being held axially by said spacers.
    The assistance washer can be centered by radial support on the spacers.
    The assistance washer can bear against the diaphragm and / or the spacer by means of an annular ring. The use of an annular ring makes it possible to limit the friction between the different surfaces in contact.
    The annular ring may be centered by radial support on the spacers.
    The ring may extend completely in a radial plane.
    In a variant, the ring may comprise a main part extending in a radial plane intended to bear on the support washer, and at least one axially extending part intended to bear against the corresponding spacer .
    The portion of the axially extending rod can axially pass through an opening of the diaphragm, the support between said portion and the spacer being located axially opposite the cover and the assistance washer, relative to the diaphragm.
    The ring is thus prevented from pivoting about its axis by pressing on the edges of the corresponding aperture of the diaphragm.
    Each spacer may comprise an axial bearing zone, for example a radially extending surface, a radial bearing zone, for example an axially extending surface, the assistance washer or the annular rod being adapted to come into support on said axial and radial bearing areas so as to ensure the centering and the axial retention of said support washer or said annular ring relative to the cover.
    The bearing areas may be formed by flat surfaces and / or curved, that is to say convex, for example.
    Each spacer may comprise a fastening portion to the cover, the axial and radial bearing zones being formed on a support plate which is distinct from the attachment portion to the cover, the said support plate being interposed axially between the fixing part and lid.
    The support plate may be mounted on said fixing portion or integral with said fixing portion. The circumferential support of the assistance washer on the diaphragm can be made on the same diameter of application as the support of the support washer on the spacer.
    This makes it possible to improve the axial compactness of the assembly. The invention also relates to a method of mounting an assembly of the aforementioned type, characterized in that it comprises the steps of: - measuring a dimension relative to the diaphragm, - measuring a dimension relative to the support washer, - choose a ring whose cross-section makes it possible to compensate for the differences between the measured dimensions of the diaphragm and the assistance washer and the reference dimensions, - fit the chosen ring between the diaphragm and the assistance washer.
    In this way, it is possible to compensate the geometrical tolerances of the diaphragm and the assistance washer, by choosing a rod having a suitable section. Indeed, the diaphragm and the assistance washer conventionally have elastic portions made by conical portions, in the manner of Belleville washers. The manufacture of such a diaphragm and such a support washer is complex and generally requires significant geometric manufacturing tolerances, which should be taken into account. The assembly according to the invention may also comprise one or more of the following features: the assistance washer is mounted axially prestressed between the spacer or the diaphragm, on the one hand, and the cover, on the other hand, the assistance washer bears on the diaphragm or on the spacer at the radially outer periphery of the assistance washer, the assistance washer bears on the cover at the level of the radially inner periphery of the assistance washer, the assistance washer has a generally conical shape. the assembly comprises support members fixed on the cover, each support member comprising a branch resting on the diaphragm and tending to hold the diaphragm bearing on the cover, each support member having a general shape; of U and comprises two branches connected by an elastically deformable part and mounted axially on either side of an edge of the diaphragm, for example a radially inner edge of the diaphragm, - one of the branches of the support member U-shaped is fixed to the lid, for example by riveting, - one of the branches of the U is fixed to the lid by means of a rivet, the other leg of the U has an opening facing the head of the rivet, able to accommodate at least part of said rivet head, - the spacer has a first end attached to the lid and a second end passing through an aperture of the diaphragm, for example an opening defined between two fingers of the d iaphragm, said second end having a first shoulder defining an axial bearing zone and a radial bearing zone capable of positioning axially and / or radially the diaphragm relative to the cover, said second end further comprising a second shoulder defining the zone; with axial support and / or the radial support zone able to position the support washer axially and / or radially with respect to the cover, the assistance washer is designed so that its maximum axial compression between its positions engaged in the new state and engaged in the worn state is between 0 and 5 mm, - the pressure plate is rotatably coupled to the lid by means of resilient tongue, axially deformable and tending to bring the plate of lid pressure. the cover comprises a radial portion comprising a radially inner peripheral edge and an outer peripheral edge which is extended by an axially extending annular portion; the diaphragm, the assistance washer, the pressure plate and / or the annular ring; are housed, at least in part, in the internal volume delimited by the cover, - the radial part of the cover comprises support zones of the diaphragm, - said bearing areas of the cover are formed by projecting zones or bosses evenly distributed over the circumference, - said bosses or protruding areas have arcuate shapes and are circumferentially spaced from each other, - the assistance washer is annular and has no axially extending lug or stud radially, for example at the level of the inner and / or outer peripheral edge, the assistance washer is annular and is provided with legs on its perimeter radially internal pherie, - the assistance washer is a piece of revolution. The invention will be better understood and other details, features and advantages of the invention will appear on reading the following description given by way of non-limiting example with reference to the accompanying drawings in which: - Figure 1 is a diagram representing the load of the diaphragm measured at the abutment, as a function of the displacement of the abutment, for different wear levels of the friction disc liners, - Figure 2 is a diagram similar to that of Figure 1, showing the load of the diaphragm measured at the stop, as a function of the displacement of the stop, taking into account the force exerted by the support washer.

    Figures 3 to 7 show an assembly 1 for a clutch device of normally closed type, according to a first embodiment. This assembly 1 comprises a lid 2 having an annular axis X.
    The terms "axial", "radial" and "circumferential" are defined by reference to the X axis.
    The cover 2 has a radial portion 3 having a radially inner peripheral edge 4 and whose outer peripheral edge is extended by an annular portion 5 extending axially. The lid 2 thus has a general bell shape delimiting an internal volume. The free end of the axial annular portion 5 comprises flanges 6 extending radially outwards, serving in particular for mounting the cover 2 on a reaction plate formed for example by a flywheel, not shown.
    The radial portion 3 of the cover 2 has protruding bearing areas 7, arc-shaped in front view, uniformly distributed over the entire circumference and angularly offset from each other. The assembly further comprises a pressure plate 8 movable axially with respect to the lid 2 and actuated by a diaphragm 9 interposed axially between the lid 2 and the pressure plate 8.
    The pressure plate 8 is coupled in rotation to the lid 2 by means of tongues 10 extending circumferentially and deformable in the radial direction, so as to return the lid 2 towards the radial portion 3 of the lid 2.
    The pressure plate 8 is movable between an engaged position, in which it is displaced by the diaphragm 9 opposite the radial portion 3 of the cover 2, so as to clamp a friction disc (not shown) against the plate of reaction, and a disengaged position in which it is biased towards the radial portion of the lid 2 by the tongues 10.
    The diaphragm 9 comprises an annular portion 11 of X axis, radially external and elastically deformable along the X axis, said annular portion 11 being generally conical in the manner of a Belleville washer. The diaphragm 9 further comprises fingers 12 extending radially inwards from the annular portion 11, the free ends of the fingers 12 serving to support a clutch abutment not shown. The fingers 12 delimit between them radial slots 13, the radially outer ends of the slots 13 having openings 14, 15 wider than the rest of the slots 13, for example openings 14, 15 of generally square or rectangular shape.
    The openings 14, 15 may have different geometries. In the embodiment shown here, the openings 14 are larger than the openings 15.
    The annular portion 11 of the diaphragm 9 is supported on the bearing areas 7 of the cover 2, so that the diaphragm 9 can tilt around said support zones 7 when it is actuated between its engaged positions (FIGS. 5 and 6). and disengaged (Figure 7). The annular portion 11 of the diaphragm 9 is also supported on the movable plate 8, in an area 16 located radially outside the bearing areas 7 of the cover 2, so as to form a lever arm. The assembly 1 further comprises U-shaped support members 17, having a first branch 18 and a second branch 19 connected by a curved zone 20 elastically deformable. The branches 18, 19 are mounted axially on either side of the internal diaphragm edge. The branch 18 of each support member is fixed to the cover by means of a rivet 21, the branch 19 having an opening 22 housing, at least in part, the corresponding head 23 of the rivet 21. The branch 19 tends to press the diaphragm 9 against the support zones 7 of the cover 2.
    The support members 17 pass through the openings 15 of the diaphragm 9 and make it possible to hold the diaphragm 9 axially and radially in position. The assembly 1 further comprises spacers 24, for example three spacers 24 uniformly distributed over the circumference. Each spacer 24 passes through an opening of the diaphragm 15. Each spacer 24 has a first end 25 fixed by riveting for example to the cover 2, and an end 26 having a radially outer shoulder 27 and a radially inner shoulder 28.
    As can be seen more clearly in FIG. 5, the radially inner shoulder 28 defines a radially extending flat surface 28a and forming an axial bearing zone capable of axially holding a support washer 29 bearing on the lid 2. The internal shoulder 28 also defines a flat surface 28b extending axially and forming a radial bearing zone capable of radially positioning the support washer 29 relative to the lid 2, that is to say capable of centering said assistance washer 29 with respect to the lid 2. The radially outer shoulder 27 defines a radially extending flat surface 27a and forming an axial bearing zone capable of axially positioning the diaphragm 9 with respect to the lid 2. The centering of the diaphragm 9 is made at the lateral sides of the spacers 24, through the openings 14.
    The support washer 29 is elastically deformable in the axial direction, said support washer 29 having a generally conical shape in the manner of a Belleville washer.
    The radially inner periphery of the support washer 29 bears directly on the radial part 3 of the cover 2, in particular at the radially inner edge 4 of the cover 2. The radially outer periphery of the support washer 29 is support on the diaphragm 9 or on the spacers 24, via an annular ring 30 extending in the radial plane. The assistance washer 29 is mounted prestressed between the cover 2, on the one hand, and the diaphragm 9 and / or the spacers 24, on the other hand.
    Note that there may be a transient phase where the rod 30 is supported simultaneously on the diaphragm 9 and the spacers 24 during the disengagement phase or clutch. This phase is stealthy and lasts only a few milliseconds. In general, the assistance washer 29 and the rod 30 bear on the one hand on the lid 2, and on the other hand either only on the spacers 24, or only on the diaphragm 9.
    The assistance washer 29, the ring 30, the diaphragm 9 and the pressure plate 8 are housed, at least in part, in the internal volume of the lid 2.
    In operation, during a disengagement phase, the user presses on the clutch pedal, so as to move the clutch abutment and thus to tilt the diaphragm 9 around the zones 7, 27 of the cover and the spacers 24 , from its engaged position shown in Figure 5 (in the absence of wear) or Figure 6 (in case of wear), to its disengaged position shown in Figure 7. The diaphragm 9 pushes the pressure plate 8 against the axial force exerted by the elastic tongues 10, so as to pinch the friction disc between the pressure plate 8 and the reaction plate. During its tilting, the diaphragm 6 is held in abutment on the cover 2 by the support members 17 and is held in abutment on the radially outer shoulders 27 of the struts 24. Furthermore, the support ring 29 is held in position. support on the cover 2, by the diaphragm 9 or by the spacers 24, regardless of the engaged or disengaged position of the diaphragm 9. Note however that the support washer 29 is supported on the spacers 24, via of the ring 30, and is not resting on the diaphragm 9 in the disengaged position. Furthermore, the assistance washer 29 is supported on the diaphragm 9, through the rod 30, and is not supported on the spacers 24 in the engaged position.
    It can be seen that the axial crushing of the assistance washer 29 in the engaged position is all the more important as the wear u of the friction disk lining is important, as can be seen in FIGS. 5 and 6, the FIG. 5 showing the engaged position with an unworn assembly, Figure 6 showing the engaged position with a worn assembly.
    The assist washer 29 is designed to allow a maximum axial compression of between 0 and 5 mm, for example.
    As before, the assistance washer 29 is designed so that the axial force to be applied at the clutch abutment (or the radially inner periphery of the fingers 12 of the diaphragm 9) to compress the washer assistance 29, referred to as the load on the abutment of the assist washer 29, varies as a function of the displacement of said clutch abutment.
    Furthermore, as previously, the diaphragm 9 and the assistance washer 29 are designed so that the total load at the stop, that is to say the effort to be provided at the clutch abutment to disengage, has a clipped portion E to reduce the maximum force to be provided at the abutment in case of wear of the friction disc linings, as shown in Figure 2. The assembly 1 according to the The invention thus makes it possible to maintain axially and radially the assistance washer 29 and the rod 30, whatever the position of the diaphragm 9, so as to avoid any phenomenon of noisiness or premature wear.
    The dimensions of the section (here the diameter of the circular section) of the annular ring 30 can be adjusted to compensate for the geometrical tolerances of the diaphragm 9 and the support ring 29.
    Figures 8 and 9 show an assembly 1 for a clutch device, according to a second embodiment. This set 1 differs from that described with reference to Figures 3 to 7 in that the ring 30 does not extend only in a radial plane. On the contrary, the annular ring 30 comprises an annular portion 31 from which three bearing zones 32 extend radially outwardly and axially towards the pressure plate 8. Each bearing zone 32 is formed by a U-shaped wire forming the rod 30, each bearing zone 32 forming an angle of between 30 and 60 °, for example of the order of 45 ° with the radial plane. The bearing zones 32 are engaged in some of the openings 14 of the diaphragm 9, whose circumferential dimensions correspond substantially to those of the bearing zones 32 of the ring 30. The ring 30 is thus coupled in rotation relative to the diaphragm 9, the ring 30 can move axially relative to said diaphragm 9. The wear of the rod 30 are reduced.
    The annular portion 31 of the ring 30 is held in abutment on the radially outer periphery of the support ring 29, as before.
    The free ends of the bearing zones 32 bear on the faces delimited by the radially internal shoulders 28 of the spacers 24, said internal shoulders 28, however, being situated axially on the other side of the diaphragm 9 in comparison with the first embodiment. illustrated in Figures 3 to 7.
    The operation of the assembly 1 according to this second embodiment remains unchanged.
    Figures 10 to 14 show an assembly 1 for a clutch device, according to a third embodiment. This set 1 differs from that described with reference to Figures 3 to 7 in that the spacers 24 are formed of two parts 24a, 24b separate from each other and integral with each other, at least after mounting spacers 24 on the cover 2.
    Each spacer 24 thus has a first portion 24a having an end 25 fixed to the lid by riveting and an end 26 having the radially outer shoulder 27 serving to support the diaphragm 9. Each spacer 24 further comprises a second portion formed by a support plate 24b, made for example by cutting and folding a sheet, said support plate 24b having a first extension 33 extending radially and a second extension 34 folded axially, said extensions 33, 34 thus forming the surfaces radial 28a and axial 28b serving to support and maintaining axial and radial position of the annular ring 30 and the assistance washer 29. The extensions 33, 34 thus form or replace the radially inner shoulder 28 of the spacer corresponding 24.
    The second part 24a may comprise a hole 35 through which the first cylindrical end 25 of the first part 24a passes, as can be seen more clearly in FIG. 13. The second part 24b can be mounted freely on the first part 24a before crimping the first part part 24a on the lid 2. After crimping, the two parts 24a, 24b are then secured to one another. The second portion 24b may also bear against a shoulder 36 of the first portion 24a, so as to axially position the second portion 24b relative to the first portion 24a.
    Alternatively, as shown in Figure 14, the first portion 24a may have projecting areas or notches 37, so as to force fit the second portion 24b on the first portion 24a so that these portions 24a, 24b are secured to each other before fixing the spacer 24 on the lid 2.
    The operation of the assembly 1 according to this third embodiment remains unchanged.
    Note that it is possible to combine the features of the embodiments described above.
