Description
L'invention concerne les dispositifs de commande d'embrayage pourThe invention relates to clutch control devices for
véhicule.vehicle.
On connaît par exemple du document DE-4029155 un dispositif de commande d'embrayage pour véhicule comprenant une pédale d'embrayage et un ressort d'assistance. DE-4029155 discloses for example a vehicle clutch control device comprising a clutch pedal and an assistance spring.
On sait en effet qu'un mécanisme d'embrayage génère un effort important sur la pédale à l'aller, c'est-à-dire lorsque le conducteur actionne cette pédale. On a ainsi illustré à la figure 1 l'évolution générale de l'effort généré sur la pédale en fonction de la course de celle-ci. C'est ainsi que l'on souhaite dans la mesure du possible conserver en dessous d'un certain seuil, appelé seuil d'effort aller maxi sur la figure, l'effort généré sur la pédale lors de la course aller. Par ailleurs, lors de la course de retour de la pédale, l'effort généré sur la pédale par le mécanisme d'assistance doit rester supérieur à un certain niveau, appelé seuil d'effort retour mini sur la courbe et ce, pour s'assurer que la pédale revient bien en position de départ. It is known in fact that a clutch mechanism generates a large force on the pedal to go, that is to say when the driver actuates this pedal. FIG. 1 thus illustrates the general evolution of the force generated on the pedal as a function of the stroke thereof. Thus it is desired as far as possible to keep below a certain threshold, referred to as the maximum effort threshold in the figure, the force generated on the pedal during the outward run. Moreover, during the return stroke of the pedal, the force generated on the pedal by the assistance mechanism must remain above a certain level, called the minimum return force threshold on the curve and this, for s' ensure that the pedal returns to the starting position.
On définit de façon générale la faculté d'assister la pédale à l'aller par l'écart entre l'effort généré sur la pédale au retour et le seuil d'effort retour mini. Cette grandeur a été indiquée par A sur la figure 1. De façon similaire, l'objectif d'assistance indiqué par B sur cette même figure est défini par l'écart entre l'effort sur la pédale à l'aller et le seuil d'effort aller maxi. It is generally defined the ability to assist the pedal to the go by the difference between the force generated on the pedal return and the minimum return force threshold. This magnitude has been indicated by A in FIG. 1. Similarly, the assistance objective indicated by B on this same figure is defined by the difference between the force on the pedal on the outward direction and the threshold of effort max.
Un dispositif d'assistance tel que celui présenté dans le document précité délivre une assistance sous la forme d'un moment exercé sur la pédale. L'intensité de ce moment évolue en fonction de la position de la pédale au cours de sa rotation. On a illustré à la figure 2 l'allure de l'évolution du moment d'assistance en fonction de l'angle de rotation de la pédale. La loi illustrée par cette courbe est un cycle d'une sinusoïde centré de part et d'autre d'un point D appelé point de chevillement. A ce point, la courbe intercepte l'axe des abscisses de sorte que l'angle concerné de rotation de la pédale correspond à un moment d'assistance nul. An assistance device such as that presented in the aforementioned document provides assistance in the form of a moment exerted on the pedal. The intensity of this moment changes according to the position of the pedal during its rotation. FIG. 2 illustrates the shape of the evolution of the assist moment as a function of the angle of rotation of the pedal. The law illustrated by this curve is a cycle of a sinusoid centered on either side of a point called D de-point. At this point, the curve intercepts the abscissa axis so that the angle of rotation of the pedal corresponds to a zero assist moment.
Les caractéristiques de cette sinusoïde correspondent aux caractéristiques du ressort (raideur et longueur libre) et à la cinématique mise en oeuvre (rayons d'accrochage du ressort au point fixe d'une part et au point mobile d'autre part). The characteristics of this sinusoid correspond to the characteristics of the spring (stiffness and free length) and to the kinematics used (attachment radii of the spring at the fixed point on the one hand and the moving point on the other hand).
La courbe précitée présente en particulier une zone de moment résistif dans laquelle la courbe d'étend au-dessus de l'axe des abscisses entre l'origine correspondant à un moment nul pour une rotation nulle et le point de chevillement D. Elle présente ensuite une zone de moment d'assistance dans laquelle le moment est négatif, délimitée par le point D et le point ultérieur pour lequel l'angle de rotation correspond à un moment nul. The aforementioned curve has in particular a zone of resistive moment in which the curve extends above the abscissa axis between the origin corresponding to a zero moment for a zero rotation and the point of anchoring D. It then presents a zone of moment of assistance in which the moment is negative, delimited by the point D and the subsequent point for which the angle of rotation corresponds to a zero moment.
Le dispositif d'assistance est normalement calé par rapport à la course de pédale indiquée par Cp sur la figure 2 de façon à distinguer une première phase et une deuxième phase. Dans la première phase (Cc), l'assistance génère un effort résistif, ce qui permet d'assurer le retour de la pédale en position haute. Cette phase est située à la fin de la zone de moment résistif. Cette phase s'achève au point de chevillement D. On fait en sorte par ailleurs que toute la suite de la course de la pédale jusqu'à la fin se situe avant la fin de la zone d'assistance pour assurer en permanence la mise sous contrainte du ressort et éviter ainsi les problèmes de battement (bruyances, à-coups, ...). The assist device is normally keyed to the pedal stroke indicated by Cp in Figure 2 so as to distinguish a first phase and a second phase. In the first phase (Cc), the assistance generates a resistive effort, which ensures the return of the pedal in the high position. This phase is located at the end of the resistive moment zone. This phase ends at the stitch D. It is also ensured that all the rest of the pedal run until the end is before the end of the assistance zone to ensure permanent spring constraint and thus avoid the problems of beat (loudness, jerks, ...).
II s'avère parfois que les valeurs A et B sont incompatibles avec une telle loi d'assistance. It sometimes turns out that the values A and B are incompatible with such a law of assistance.
Un but de l'invention est de proposer un dispositif de commande d'embrayage permettant de choisir avec plus de souplesse les grandeurs A et B, c'est-à-dire les efforts d'assistance aller et retour, afin de concilier le mieux possible l'efficacité de l'assistance et le confort d'utilisation de l'embrayage. An object of the invention is to provide a clutch control device allowing to choose more flexibly the quantities A and B, that is to say, the assistance efforts back and forth, in order to reconcile the best possible efficiency of assistance and comfort of use of the clutch.
A cet effet, on prévoit selon l'invention un dispositif d'embrayage pour véhicule comprenant: - une pédale d'embrayage; et - un ressort d'assistance pour solliciter la pédale dans le sens du débrayage, le dispositif comprenant un deuxième ressort d'assistance pour solliciter la pédale dans le sens du débrayage. For this purpose, there is provided according to the invention a clutch device for a vehicle comprising: - a clutch pedal; and an assisting spring for biasing the pedal in the disengagement direction, the device comprising a second assisting spring for biasing the pedal in the disengagement direction.
Ainsi, la présence du deuxième ressort offre plus de liberté pour concevoir le dispositif de commande. On peut par exemple limiter l'effort d'assistance retour pour un même effort d'assistance aller ou au contraire augmenter l'effort d'assistance aller pour un même effort d'assistance retour. L'invention permet d'introduire un degré de liberté dans la relation liant les deux grandeurs A et B et d'amplifier leur différence de niveau d'effort. Thus, the presence of the second spring provides more freedom to design the control device. One can for example limit the return assistance effort for the same assistance effort to go or on the contrary increase the assistance effort to go for the same return assistance effort. The invention makes it possible to introduce a degree of freedom in the relationship linking the two magnitudes A and B and to amplify their difference in level of effort.
Le dispositif selon l'invention pourra présenter en outre au moins l'une quelconque des caractéristiques suivantes: - les deux ressorts sont disposés en série; - le deuxième ressort a une raideur inférieure à celle du premier ressort; - il comprend au moins une entretoise présentant au moins une face sur laquelle prend appui au moins l'un des deux ressorts; l'entretoise ou l'une des entretoises présente deux faces sur lesquelles prennent appui les deux ressorts respectifs; - la ou chaque entretoise comprend une tige sur laquelle est enfilée l'un des ressorts; - la ou chaque entretoise est montée mobile à coulissement sur une pièce de guidage; et - il comprend deux entretoises associées aux ressorts respectifs. The device according to the invention may also have at least one of the following characteristics: the two springs are arranged in series; the second spring has a stiffness lower than that of the first spring; - It comprises at least one spacer having at least one face on which bears at least one of the two springs; the spacer or one of the spacers has two faces on which support the two respective springs; - The or each spacer comprises a rod on which is threaded one of the springs; the or each spacer is slidably mounted on a guide piece; and - it comprises two spacers associated with the respective springs.
D'autres caractéristiques et avantages de l'invention apparaîtront encore dans la description suivante d'un mode préféré de réalisation donné à titre d'exemple non limitatif en référence aux dessins annexés sur lesquels: - la figure 1 illustre l'évolution de l'effort généré sur la pédale par un dispositif de commande classique en fonction de la course de la pédale; - la figure 2 illustre l'évolution du moment d'assistance de la pédale en fonction de l'angle de rotation de la pédale pour un dispositif de commande classique; - les figures 3 et 4 sont deux vues respectives de face et de gauche d'un dispositif de commande selon l'invention; - la figure 5 est une vue partielle en coupe du dispositif de la figure 4 suivant le plan V-V; - la figure 6 est une vue schématique des deux ressorts du dispositif de la figure 4; et - la figure 7 est une vue analogue à la figure 2 correspondant au dispositif des figures 3 et 4. Other characteristics and advantages of the invention will become apparent in the following description of a preferred embodiment given by way of non-limiting example with reference to the appended drawings, in which: FIG. 1 illustrates the evolution of the force generated on the pedal by a conventional control device according to the pedal stroke; FIG. 2 illustrates the evolution of the assist moment of the pedal as a function of the angle of rotation of the pedal for a conventional control device; FIGS. 3 and 4 are two respective front and left views of a control device according to the invention; - Figure 5 is a partial sectional view of the device of Figure 4 along the plane V-V; - Figure 6 is a schematic view of the two springs of the device of Figure 4; and - Figure 7 is a view similar to Figure 2 corresponding to the device of Figures 3 and 4.
On a illustré un dispositif de commande d'embrayage pour véhicule selon l'invention aux figures 3 à 5. There is illustrated a vehicle clutch control device according to the invention in Figures 3 to 5.
Le dispositif 2 comprend une pédale d'embrayage 4 ainsi qu'un 10 support 6 fixe par rapport à la caisse du véhicule. The device 2 comprises a clutch pedal 4 and a support 6 fixed relative to the vehicle body.
La pédale est montée mobile à rotation sur ce support autour d'un axe horizontal 8 voisin d'une extrémité supérieure de la pédale et perpendiculaire à la direction de marche du véhicule. The pedal is rotatably mounted on this support about a horizontal axis 8 adjacent to an upper end of the pedal and perpendicular to the direction of travel of the vehicle.
Le dispositif 2 comprend deux ressorts d'assistance 10, 12 destinés à solliciter la pédale dans le sens du débrayage, c'est-à-dire dans le sens de la flèche 14 illustrée à la figure 4. Ce sens de déplacement correspond à l'actionnement de la pédale par le conducteur en vue du débrayage. The device 2 comprises two assist springs 10, 12 for biasing the pedal in the disengagement direction, that is to say in the direction of the arrow 14 illustrated in FIG. 4. This direction of movement corresponds to the pedal actuation by the driver for disengagement.
Les deux ressorts 10, 12 sont dans le présent exemple disposés en série l'un avec l'autre. The two springs 10, 12 are in the present example arranged in series with each other.
Par ailleurs, le deuxième ressort 12 a une raideur inférieure à celle du premier ressort 10. Moreover, the second spring 12 has a stiffness lower than that of the first spring 10.
La disposition des deux ressorts a été illustrée schématiquement pour plus de clarté à la figure 6. Une extrémité supérieure 16 du premier ressort 10 est fixée de façon articulée au support 6 autour d'un axe horizontal 18 parallèle à l'axe 8. De façon similaire, une extrémité inférieure 20 du deuxième ressort 12 est fixée de façon articulée à la pédale 4 autour d'un axe de rotation 22 parallèle à l'axe 18. The arrangement of the two springs has been schematically illustrated for the sake of clarity in FIG. 6. An upper end 16 of the first spring 10 is hingedly attached to the support 6 about a horizontal axis 18 parallel to the axis 8. Similarly, a lower end 20 of the second spring 12 is hingedly attached to the pedal 4 about an axis of rotation 22 parallel to the axis 18.
Dans le présent exemple, le dispositif d'assistance comprend une entretoise 24 comportant une platine 26 en forme de disque et une tige 28 dont une extrémité est fixée au centre de l'une des deux faces principales de la platine et l'autre extrémité est en appui sur l'axe 22. Le deuxième ressort 12 est enfilé sur la tige 28 de sorte qu'il prend appui par son extrémité supérieure 30 contre la face précitée de la platine et par son extrémité inférieure 20 sur l'axe 22 comme indiqué plus haut. La tige 28 a un axe longitudinal perpendiculaire aux axes 18 et 22 et interceptant ceux-ci. Par ailleurs, le premier ressort 10 prend appui par son extrémité inférieure contre l'autre face de la platine. Ainsi, les deux ressorts 10 et 12 prennent appui sur les deux faces opposées de la platine respectivement. In the present example, the assistance device comprises a spacer 24 comprising a disk-shaped plate 26 and a rod 28, one end of which is fixed in the center of one of the two main faces of the plate and the other end is resting on the axis 22. The second spring 12 is threaded on the rod 28 so that it is supported by its upper end 30 against the aforementioned face of the plate and by its lower end 20 on the axis 22 as indicated upper. The rod 28 has a longitudinal axis perpendicular to the axes 18 and 22 and intercepting them. Furthermore, the first spring 10 is supported by its lower end against the other face of the plate. Thus, the two springs 10 and 12 bear on the two opposite faces of the plate respectively.
Un exemple plus précis de réalisation de ce montage a été illustré à la figure 5. On y voit en particulier que la tige 28 est creuse et reçoit un tube de guidage 25 supportant les deux ressorts 10, 12. Le dispositif comprend une deuxième entretoise 27 avec une platine 29 sur laquelle prend appui l'extrémité supérieure du premier ressort 10 et une tige creuse 31 montée elle aussi sur le tube 25. Les deux tiges 28 et 31 sont mobiles à coulissement sur le tube 25, l'une derrière l'autre. A more specific example of embodiment of this assembly has been illustrated in FIG. 5. It is seen in particular that the rod 28 is hollow and receives a guide tube 25 supporting the two springs 10, 12. The device comprises a second spacer 27 with a plate 29 on which bears the upper end of the first spring 10 and a hollow rod 31 also mounted on the tube 25. The two rods 28 and 31 are slidably movable on the tube 25, one behind the other.
On prévoit dans ce dispositif que les deux ressorts demeurent sous contrainte durant toute la course de la pédale entre les deux extrémités de cette course. Les ressorts sont des ressorts de compression. It is expected in this device that the two springs remain under stress during the entire stroke of the pedal between the two ends of this race. The springs are compression springs.
La disposition de ces deux ressorts notamment en série a pour avantage que les lois d'assistance de chaque ressort illustrées dans leur principe à la figure 1 se cumulent l'une avec l'autre comme illustré à la figure 7 sur laquelle on a présenté les courbes 40, 42 correspondant respectivement au premier ressort 10 et au deuxième ressort 12. Un tel agencement permet de limiter l'effort d'assistance retour pour un même effort d'assistance aller. Dans une autre version, il permet d'augmenter l'effort d'assistance aller pour un même effort d'assistance retour. L'invention permet donc d'introduire un degré de liberté dans la relation liant les deux grandeurs A et B et d'amplifier leur différence de niveau d'effort. On a en particulier illustré à la figure 7 que l'effort d'assistance retour correspondant à un moment négatif peut être proche de l'axe des abscisses, tandis que l'effort d'assistance aller reste à un niveau très bas de sorte que son intensité est élevée en valeur absolue. The provision of these two springs in particular in series has the advantage that the assistance laws of each spring illustrated in principle in Figure 1 are cumulative with each other as shown in Figure 7 which has been presented. curves 40, 42 respectively corresponding to the first spring 10 and the second spring 12. Such an arrangement allows to limit the return assistance effort for the same assistance effort go. In another version, it makes it possible to increase the assistance effort going for the same return assistance effort. The invention therefore makes it possible to introduce a degree of freedom in the relationship linking the two magnitudes A and B and to amplify their difference in level of effort. In particular, it has been illustrated in FIG. 7 that the return assistance force corresponding to a negative moment may be close to the abscissa axis, while the going assistance effort remains at a very low level so that its intensity is high in absolute value.
Bien entendu, on pourra apporter à l'invention de nombreuses modifications sans sortir du cadre de celle-ci. Of course, we can bring to the invention many changes without departing from the scope thereof.
On pourra envisager que les deux ressorts ne sont pas disposés en série. It can be envisaged that the two springs are not arranged in series.
