Description

AUTOMOBILE, ET EMBRAYAGE MUNI DE CETTE BUTEE AUTOMOBILE, AND CLUTCH PROVIDED WITH THIS STOPPING
La présente invention concerne une butée de commande d'embrayage, notamment de véhicule automobile, et un embrayage muni de cette butée.The present invention relates to a clutch control stop, particularly a motor vehicle, and a clutch provided with this stop.
Dans un véhicule automobile, un embrayage est destiné à coupler un organe rotatif menant (généralement un vilebrequin d'un moteur du véhicule automobile) et un organe rotatif mené (généralement un arbre d'entrée d'une boîte de vitesses du véhicule automobile). Habituellement, les axes de rotation des organes rotatifs menant et mené sont sensiblement parallèles et légèrement décalés radialement.In a motor vehicle, a clutch is intended to couple a rotary driving member (generally a crankshaft of a motor vehicle engine) and a driven rotary member (generally an input shaft of a gearbox of the motor vehicle). Usually, the axes of rotation of the rotating members driving and driven are substantially parallel and slightly radially offset.
L'embrayage comporte au moins un mécanisme entraîné en rotation par l'organe menant. Ce mécanisme comprend un couvercle, un diaphragme et un plateau de pression tous liés en rotation avec l'organe menant.The clutch comprises at least one mechanism driven in rotation by the driving member. This mechanism comprises a lid, a diaphragm and a pressure plate all connected in rotation with the driving member.
Afin de coupler les organes rotatifs menant et mené, le diaphragme enserre un disque de friction, lié en rotation avec l'organe rotatif mené, entre le plateau de pression et un plateau de réaction solidaire en rotation du couvercle.In order to couple the driving and driven rotating members, the diaphragm encloses a friction disk, connected in rotation with the driven rotary member, between the pressure plate and a reaction plate secured to rotate the lid.
Le diaphragme est généralement manœuvré par une butée de commande déplaçable axialement.The diaphragm is generally operated by an axially displaceable control stop.
Ainsi, on connaît déjà dans l'état de la technique, notamment d'après FR-A- 2 854 215, une butée de commande d'embrayage, notamment de véhicule automobile, du type comportant des moyens de roulement agencés entre un organe de poussée fixe en rotation et un organe de butée rotatif destiné à coopérer avec un diaphragme de l'embrayage, l'organe de butée étant susceptible de se déplacer radialement par rapport à l'organe de poussée.Thus, it is already known in the state of the art, particularly from FR-A-2,854,215, a clutch control stopper, particularly a motor vehicle, of the type comprising rolling means arranged between a control member. thrust fixed in rotation and a rotary stop member for cooperating with a diaphragm of the clutch, the stop member being movable radially relative to the thrust member.
La butée de commande est habituellement déplacée axialement par une fourchette articulée sur un carter fixe de la transmission du véhicule ou par un vérin hydraulique. Lorsque la butée de commande se déplace axialement, l'organe de butée coopère avec le diaphragme de manière à le manœuvrer. Les moyens de roulement permettent une rotation de l'organe de butée par rapport à l'organe de poussée.The control stop is usually moved axially by a fork hinged to a fixed housing of the vehicle transmission or by a hydraulic cylinder. When the control stop moves axially, the stop member cooperates with the diaphragm so as to maneuver. The rolling means allow a rotation of the abutment member relative to the thrust member.
Afin d'assurer un bon fonctionnement de la butée de commande, les organes de butée et de poussée sont de préférence centrés respectivement sur l'axe de l'organe rotatif menant et sur l'axe de l'organe rotatif mené.To ensure proper operation of the control stop, the abutment and thrust members are preferably centered respectively on the axis of the rotary rotating member and on the axis of the driven rotary member.
Le centrage de l'organe de poussée est généralement réalisé de façon statique en montant cet organe de poussée de façon coulissante axialement sur un guide fixe tubulaire coaxial avec l'organe rotatif mené. Par contre, le centrage de l'organe de butée est généralement réalisé de façon dynamique.The centering of the thrust member is generally made statically by mounting this thrust member sliding axially on a fixed tubular guide coaxial with the driven rotary member. On the other hand, the centering of the abutment member is generally carried out dynamically.
En effet, dans FR-A-2 854 215, les moyens de roulement comprennent des rouleaux en contact avec deux chemins de roulement opposés portés respectivement par une bague d'appui axial distale, liée en rotation avec l'organe de butée, et une bague d'appui axial proximale, susceptible de coopérer avec l'organe de poussée.Indeed, in FR-A-2 854 215, the rolling means comprise rollers in contact with two opposite raceways respectively carried by a distal axial bearing ring, connected in rotation with the stop member, and a proximal axial bearing ring, capable of cooperating with the thrust member.
Ce type de moyens de roulement autorise des jeux radiaux entre l'organe de poussée et l'organe de butée. Ces jeux radiaux rendent possible le déplacement radial de l'organe de butée par rapport à l'organe de poussée.This type of rolling means allows radial clearances between the thrust member and the stop member. These radial clearances make possible the radial displacement of the abutment member relative to the thrust member.
Ainsi, lors du fonctionnement de l'embrayage, l'organe de butée, coopérant avec le diaphragme en rotation, se déplace radialement de manière à se centrer sur l'axe de cet embrayage, qui est sensiblement aligné avec l'axe de l'organe rotatif menant. Le centrage de l'organe de butée par rapport au diaphragme se fait donc de façon dynamique.Thus, during the operation of the clutch, the stop member, cooperating with the rotating diaphragm, moves radially so as to center on the axis of this clutch, which is substantially aligned with the axis of the clutch. rotating member driving. The centering of the abutment member with respect to the diaphragm is therefore dynamic.
Toutefois, dans certaines conditions de fonctionnement de l'embrayage, le centrage dynamique de l'organe de butée par rapport au diaphragme n'atteint pas la précision souhaitée.However, under certain operating conditions of the clutch, the dynamic centering of the abutment member relative to the diaphragm does not reach the desired accuracy.
L'invention a notamment pour but d'améliorer le centrage de l'organe de butée sur l'axe de l'organe rotatif menant, sans nuire ni à la qualité du centrage de l'organe de poussée sur l'axe de l'organe rotatif mené, ni au bon fonctionnement de la butée de commande.The object of the invention is in particular to improve the centering of the abutment member on the axis of the rotary driving member, without impairing the quality of the centering of the thrust member on the axis of the thrust member. driven rotating member, nor to the correct operation of the control stop.
A cet effet, l'invention a pour objet une butée de commande du type précité, où l'organe de butée est muni de moyens de centrage statique par rapport au diaphragme.For this purpose, the invention relates to a control stopper of the aforementioned type, wherein the stop member is provided with static centering means relative to the diaphragm.
Grâce aux moyens de centrage statique, il est possible de centrer avec précision l'organe de butée par rapport à l'axe de rotation du diaphragme dès le montage de la butée de commande sur le mécanisme d'embrayage, et de maintenir l'organe de butée dans une position centrée satisfaisante lors du fonctionnement.Thanks to the static centering means, it is possible to accurately center the abutment member relative to the axis of rotation of the diaphragm as soon as the control stopper is mounted on the clutch mechanism, and to hold the body stop in a satisfactory center position during operation.

Les rouleaux 26 sont agencés dans une cage 31 formée par une plaque ajourée parallèle aux chemins de roulement 27D, 27P.The rollers 26 are in contact with two opposite raceways 27D, 27P, respectively carried by a distal axial bearing ring 28, connected in rotation with the abutment member 14, and a proximal axial bearing ring 30. rollers 26 are arranged in a cage 31 formed by a perforated plate parallel to the raceways 27D, 27P.
La bague d'appui axial proximale 30 est munie d'une face de poussée 32 comportant un enfoncement de centrage 34 destiné à coopérer avec un bossage annulaire 36 de l'organe de poussée 12.The proximal axial bearing ring 30 is provided with a thrust face 32 having a centering depression 34 intended to cooperate with an annular boss 36 of the thrust member 12.
La bague d'appui distale 28 est prolongée axialement par deux parois annulaires 38, 40 respectivement radialement externe et interne. Dans le premier mode de réalisation de l'invention, les parois annulaires 38, 40 sont venues de matière avec la bague d'appui distale 28.The distal support ring 28 is extended axially by two annular walls 38, 40 respectively radially external and internal. In the first embodiment of the invention, the annular walls 38, 40 are integral with the distal support ring 28.
L'organe de butée 14 est accroché à la paroi annulaire externe 38 prolongeant la bague d'appui distale 28 par exemple par emboîtement serré.The abutment member 14 is hooked to the outer annular wall 38 extending the distal support ring 28 for example by tight interlocking.
Les bagues d'appui proximale 30 et distale 28 ainsi que les parois 38, 40 délimitent un logement dans lequel sont agencés les moyens de roulement 16. Ce logement contient généralement un produit lubrifiant destiné à limiter les frottements dans les moyens de roulement 16, notamment afin d'éviter d'éventuelles surchauffes des éléments de roulement 26. Le logement est obturé par des moyens d'étanchéité 42 comportant des joints d'étanchéité 44 en matériau plastique, par exemple du type à lèvre.The proximal 30 and distal support rings 28 and the walls 38, 40 delimit a housing in which the rolling means 16 are arranged. This housing generally contains a lubricant intended to limit the friction in the rolling means 16, in particular to prevent possible overheating of the rolling elements 26. The housing is closed by sealing means 42 having seals 44 of plastic material, for example of the lip type.
Les joints d'étanchéité 44 sont portés chacun par un élément de support annulaire 46 fixé par exemple par sertissage sur la paroi annulaire externe 38 ou interne 40. La lèvre de chaque joint d'étanchéité 44 coopère avec la bague d'appui proximale 30. Les joins d'étanchéité 44 sont fixés sur les supports 46 de façon connue en soi, par exemple par adhérisation ou par collage.The seals 44 are each carried by an annular support member 46 fixed for example by crimping on the outer annular wall 38 or inner 40. The lip of each seal 44 cooperates with the proximal bearing ring 30. The sealing joints 44 are fixed on the supports 46 in a manner known per se, for example by bonding or gluing.
On notera que ces moyens d'étanchéité 42 permettent une lubrification à vie des moyens de roulement 16. II existe généralement un défaut d'alignement, représenté par la distance D sur la figure 1 , entre les axes des organes rotatifs menant et menés.It will be noted that these sealing means 42 allow a lifetime lubrication of the rolling means 16. There is generally a misalignment, represented by the distance D in FIG. 1, between the axes of the rotating and driving members.
Afin d'assurer un bon fonctionnement de la butée de commande 10, l'organe de poussée 12 est de préférence centré sur l'axe de l'organe rotatif mené et l'organe de butée 14 est de préférence centré sur l'axe de l'organe rotatif menant.In order to ensure proper operation of the control stop 10, the thrust member 12 is preferably centered on the axis of the driven rotary member and the abutment member 14 is preferably centered on the axis of rotation. the rotating member driving.
Le centrage de l'organe de poussée 12 est réalisé de manière classique lors de son montage sur le guide tubulaire 22.The centering of the thrust member 12 is conventionally achieved when it is mounted on the tubular guide 22.
Par ailleurs, le centrage de l'organe de butée 14 est réalisé grâce à des moyens de centrage statique 48 agencés sur cet organe de butée 14, représentés plus en détail sur la figure 2.Furthermore, the centering of the abutment member 14 is achieved by means of static centering means 48 arranged on this abutment member 14, shown in more detail in FIG. 2.
Les moyens de centrage statique 48 comprennent six pions de centrage 50, répartis circonférentiellement sur l'organe de butée 14, destinés à s'insérer chacun entre deux doigts 18D du diaphragme 18. Le diaphragme 18 étant coaxial avec l'organe rotatif menant, grâce aux moyens de centrage statique 48, l'organe de butée 14 reste centré par rapport à l'organe rotatif menant lors du fonctionnement de l'embrayage.The static centering means 48 comprise six centering pins 50, circumferentially distributed on the abutment member 14, intended to be inserted each between two fingers 18D of the diaphragm 18. The diaphragm 18 being coaxial with the rotary member driving, thanks the static centering means 48, the stop member 14 remains centered relative to the rotary member driving during operation of the clutch.
Les pions de centrage 50 sont généralement réalisés lors du moulage de l'organe de butée 14.The centering pins 50 are generally made during the molding of the abutment member 14.
En variante, l'organe de butée 14 peut être réalisé en tôle. Dans ce cas, les pions de centrage sont généralement des pattes de l'organe de butée 14, repliées axialement.Alternatively, the abutment member 14 may be made of sheet metal. In this case, the centering pins are generally tabs of the abutment member 14, folded axially.
L'organe de butée 14 comporte en outre des moyens d'accrochage 52 sur le diaphragme 18.The stop member 14 further comprises hooking means 52 on the diaphragm 18.
Dans le premier mode de réalisation de l'invention, les moyens d'accrochage 52 comportent les pions de centrage 50, accrochés par pincement entre deux doigts 18D du diaphragme 18.In the first embodiment of the invention, the attachment means 52 comprise the centering pegs 50 hooked by pinching between two fingers 18D of the diaphragm 18.
En variante, les moyens d'accrochage 52 pourraient comporter des pions d'accrochage supplémentaires, répartis circonférentiellement, coopérant par encliquetage avec les deux doigts adjacents correspondants 18D du diaphragme 18.As a variant, the hooking means 52 could comprise additional attachment studs, circumferentially distributed, coacting with the two corresponding adjacent fingers 18D of the diaphragm 18.
Selon une autre variante, les moyens d'accrochage 52 pourraient comporter des pions d'accrochage, chacun en forme de rouleau fendu de façon à coopérer par déformation élastique radiale avec deux doigts adjacents correspondants 18D du diaphragme 18.According to another variant, the attachment means 52 could comprise attachment pegs, each in the form of a split roll so as to cooperate by radial elastic deformation with two corresponding adjacent fingers 18D of the diaphragm 18.
Afin que les centrages statiques respectifs des organes de butée 14 et de poussée 12 sur des axes décalés radialement l'un par rapport à l'autre ne nuisent pas au bon fonctionnement de la butée de commande 10, il est prévu que l'organe de butée 14 soit déplaçable radialement par rapport à l'organe de poussée 12. Ainsi, les bagues d'appui proximale 30 (coopérant avec l'organe de poussée 12), et distale 28 (fixée à l'organe de butée 14) sont susceptibles de se déplacer radialement l'une par rapport à l'autre, sur une course au moins égale au double de la distance D entre les axes des organes rotatifs menant et mené.So that the respective static centering of the abutment members 14 and thrust members 12 on radially offset axes with respect to one another does not interfere with the proper operation of the control stopper 10, it is intended that the stop 14 is movable radially relative to the thrust member 12. Thus, the rings proximal support 30 (cooperating with the thrust member 12), and distal 28 (fixed to the abutment member 14) are capable of moving radially relative to each other, on a stroke at least equal to twice the distance D between the axes of the rotary organs driving and driven.
Ce déplacement est autorisé par des jeux radiaux J1 et J2, respectivement, entre la bague d'appui proximale 30 et la paroi annulaire interne 38, et entre la bague d'appui proximale 30 et la paroi annulaire externe 40.This movement is authorized by radial clearances J1 and J2, respectively, between the proximal bearing ring 30 and the inner annular wall 38, and between the proximal bearing ring 30 and the outer annular wall 40.
Sur les figures 3 et 4, on a représenté une butée de commande 10 selon respectivement des deuxième et troisième modes de réalisation de l'invention. Sur ces figures, les éléments analogues à ceux de la figure 1 sont désignés par des références identiques.FIGS. 3 and 4 show a control stop 10 according to the second and third embodiments of the invention respectively. In these figures, elements similar to those of Figure 1 are designated by identical references.
Selon le deuxième mode de réalisation, décrit en référence à la figure 3, l'organe de butée 14 est réalisé en tôle. Cet organe de butée 14 est accroché sur la bague d'appui distale 28 par pincement autour de la paroi annulaire externe 38.According to the second embodiment, described with reference to Figure 3, the stop member 14 is made of sheet metal. This abutment member 14 is hooked on the distal support ring 28 by pinching around the outer annular wall 38.
On notera que, à la différence du premier mode de réalisation, les parois annulaires 38 et 40 sont rapportées sur la bague d'appui distale 28. Ainsi, les bagues d'appui proximale 30 et distale 28 pourront être fabriquées en acier traité adapté pour former le chemin de roulement, alors que les parois annulaires 38 et 40 pourront être fabriquées en un acier plus commun.It will be noted that, unlike the first embodiment, the annular walls 38 and 40 are attached to the distal support ring 28. Thus, the proximal and distal support rings 28 may be made of treated steel adapted to forming the raceway, while the annular walls 38 and 40 can be made of a more common steel.
On notera par ailleurs que les joints d'étanchéité 44 sont portés par les parois annulaires 38 et 40.Note also that the seals 44 are carried by the annular walls 38 and 40.
On notera également que, à la différence du premier mode de réalisation, la face de poussée 32 de la bague d'appui proximale est plane, autorisant ainsi un glissement radial relatif entre le bossage annulaire 36 et cette face de poussée 32 sur une course au moins égale au double de la distance D entre les axes des organes rotatifs menant et mené.It will also be noted that, unlike the first embodiment, the thrust surface 32 of the proximal bearing ring is flat, thus allowing relative radial sliding between the annular boss 36 and this thrust surface 32 on a stroke at less than twice the distance D between the axes of the rotating and driven rotating members.
Les débattements radiaux de la bague d'appui proximale 30 sont limités par un jeu J1 d'environ quelques dixièmes de millimètre.The radial deflections of the proximal bearing ring 30 are limited by a clearance J1 of about a few tenths of a millimeter.
Selon le troisième mode de réalisation, décrit en référence à la figure 4, la bague d'appui proximale 30 est solidaire de l'organe de poussée 12. Cette bague d'appui proximale 30 est par exemple venue de matière avec l'organe de poussée 12.According to the third embodiment, described with reference to FIG. 4, the proximal support ring 30 is integral with the thrust member 12. This proximal bearing ring 30 is for example integral with the thrust 12.
Par ailleurs, la bague d'appui distale 28 n'est pas prolongée axialement par des parois annulaires. Dans ce cas, les joints d'étanchéité 44 sont portés par l'organe de butée 14.Furthermore, the distal support ring 28 is not extended axially by annular walls. In this case, the seals 44 are carried by the abutment member 14.
On notera, parmi les avantages de l'invention, que, l'organe de butée 14 pouvant être accroché au diaphragme 18, il est possible d'assembler, hors chaîne de montage du véhicule automobile, l'embrayage et l'organe de butée. Ainsi, l'embrayage et l'organe de butée 14 forment un ensemble prêt à être monté sur le véhicule automobile, l'organe de butée étant déjà centré par rapport à l'embrayage.It will be noted, among the advantages of the invention, that the abutment member 14 can be hooked to the diaphragm 18, it is possible to assemble, off-line mounting of the motor vehicle, the clutch and the stop member. Thus, the clutch and the stop member 14 form an assembly ready to be mounted on the motor vehicle, the abutment member being already centered with respect to the clutch.
On notera enfin que le fonctionnement de la butée de commande 10 est facilement adaptable pour une butée de type tiré. Finally, note that the operation of the control stop 10 is easily adaptable for a fired type stop.
