Description
La présente invention concerne un dispositif mécanique permettant deThe present invention relates to a mechanical device for
transformer la sélection classique et complexe en H d'une boîte de vitesse automobile conventionnelle en sélection linéaire simple (comme sur une moto, ou comme sur une automobile équipée d'une boîte de. vitesse séquentielle). transform the classic and complex H-selection from a conventional automotive gearbox into a simple linear selection (like on a motorcycle, or like an automobile equipped with a sequential gearbox).
L'usage d'un tel dispositif est destiné à la compétition automobile principalement (des applications peuvent également être envisagées sur des véhicules de série). Ce dispositif se présente sous forme d'un module qui se fixe à la place du levier de vitesses d'origine du véhicule. Il est constitué d'un levier de sélection à mouvement linéaire dit séquentiel et d'un ensemble cinématique permettant de transformer ce mouvement unique linaire en deux mouvements linéaires aptes à commander la boîte de vitesse. The use of such a device is intended for motor racing mainly (applications can also be considered on production vehicles). This device is in the form of a module which is fixed in place of the original shifter of the vehicle. It consists of a sequential linear motion selection lever and a kinematic assembly for transforming this single linear motion into two linear movements able to control the gearbox.
Le but d'un tel système est de gagner du temps lors des changement de rapports. En effet, lors d'un changement de rapport, le véhicule n'est plus motorisé. En d'autre termes, il ralentit. Pour être performant, il est donc nécessaire de trouver un moyen de diminuer ce temps. Sur une boîte de vitesse conventionnelle, deux à trois mouvements du bras sont nécessaires pour enclencher le rapport voulu. Par exemple, pour passer de seconde en troisième, il faut obligatoirement un mouvement longitudinal pour sortir la seconde, puis un mouvement transversal pour sélectionner le bon groupe de vitesses (ici le groupe troisième et quatrième), phis à nouveau un mouvement longitudinal pour enclencher la troisième. The purpose of such a system is to save time when changing reports. Indeed, when changing gear, the vehicle is no longer motorized. In other words, it slows down. To be successful, it is necessary to find a way to reduce this time. On a conventional gearbox, two to three arm movements are required to engage the desired gear. For example, to pass from second to third, it is necessary to move longitudinally to get out the second, then a transverse movement to select the right group of speeds (here the third and fourth group), again a longitudinal movement to engage the third.
Avec le dispositif de l'invention, un seul mouvement longitudinal est nécessaire pour passer d'un 20 rapport à l'autre. With the device of the invention, only one longitudinal movement is necessary to move from one report to the other.
D'autres possibilités permettent actuellement d'obtenir un résultat similaire: -Monter une boîte de vitesses séquentielle. La solution est efficace mais elle coûte très cher, et elle est limitée aux modèles de véhicules pour lesquels ces boîtes de vitesses sont fabriquées. -Robotiser une boîte de vitesse conventionnelle. Le conducteur appuie sur un bouton, l'information est traitée par un système électronique et des actionneurs se chargent d'enclencher le rapport voulu. La solution est également très onéreuse, complexe et le poids de l'ensemble n'est pas négligeable. Other possibilities currently make it possible to obtain a similar result: - To assemble a sequential gearbox. The solution is effective but it is very expensive, and it is limited to the vehicle models for which these gearboxes are manufactured. -Robotise a conventional gearbox. The driver presses a button, the information is processed by an electronic system and actuators are responsible for triggering the desired report. The solution is also very expensive, complex and the weight of the whole is not negligible.
Le mécanisme selon l'invention permet d'obtenir une solution beaucoup moins onéreuse que les solutions évoquées précédemment. De plus, après quelques légères adaptations, il peut se monter sur la plupart des véhicules du marché. Son poids est relativement faible et sa simplicité permet au pilote de réaliser le montage et l'entretien lui-même sans difficultés particulières. The mechanism according to the invention makes it possible to obtain a solution which is much less expensive than the solutions mentioned above. In addition, after some slight adjustments, it can be mounted on most vehicles on the market. Its weight is relatively low and its simplicity allows the pilot to carry out assembly and maintenance himself without particular difficulties.
Le dispositif selon l'invention se fixe à l'emplacement du levier de vitesses d'origine. Il dispose d'un levier de sélection (1). Des câbles (2 et 2bis) relient ledit dispositif à la boîte de vitesse d'origine. The device according to the invention is fixed at the location of the original gear lever. It has a selection lever (1). Cables (2 and 2bis) connect said device to the original gearbox.
Le levier de sélection (1) entraîne en rotation un arbre (3) solidaire de deux disques (4 et 4bis) dans lesquels sont inscrits des chemins (9 et 9bis). La rotation de ces disques (4 et 4bis) a pour rôle de recomposer les mouvements nécessaires à la boîte de vitesse pour enclencher les rapports. A un des disques (4 et 4bis) correspond la tâche de sélectionner la gamme de vitesses, à l'autre celle de l'enclenchement du rapport. The selection lever (1) rotates a shaft (3) integral with two disks (4 and 4a) in which are written paths (9 and 9a). The rotation of these disks (4 and 4bis) has the role of recomposing the movements necessary for the gearbox to engage the reports. To one of the disks (4 and 4bis) corresponds the task of selecting the range of speeds, to the other that of the engagement of the report.
Il y a sept positions angulaires fixes pour l'ensemble arbre(3) + disques(4 et 4bis) ( cinq vitesses + point mort + marche arrière). A chacune de ces sept positions correspond un rapport. L'angle entre chaque position angulaire fixe se situe entre 20 degrés et 60 degrés, mais idéalement il est de 54 degrés. There are seven fixed angular positions for the shaft assembly (3) + discs (4 and 4a) (five speeds + neutral + reverse). At each of these seven positions corresponds a report. The angle between each fixed angular position is between 20 degrees and 60 degrees, but ideally it is 54 degrees.
Les chemins (9 et 9bis) sont définis selon les trajectoires (10 et 10bis) que doivent emprunter les doigts (5 et 5bis). Les trajectoires (10 et 10 bis) des doigts (5 et 5 bis) sont définies de manière à recomposer les mouvements nécessaires au passage des vitesses. Ces trajectoires (10 et 10bis) suivent les cercles primitifs concentriques (en pointillés fig.3 et 4) dans les phases où le câble (2 et 2bis) concerné ne doit pas bouger. Ces trajectoires (10 et 10 bis) passent d'un cercle primitif à l'autre pour faire se déplacer le câble (2 et 2bis) concerné. The paths (9 and 9bis) are defined according to the trajectories (10 and 10bis) to be used by the fingers (5 and 5bis). The trajectories (10 and 10 bis) of the fingers (5 and 5 bis) are defined so as to recompose the movements necessary for shifting gears. These trajectories (10 and 10bis) follow the concentric primitive circles (dashed fig.3 and 4) in the phases where the cable (2 and 2bis) concerned must not move. These trajectories (10 and 10 bis) pass from one pitch circle to another to move the cable (2 and 2bis) concerned.
Les pentes sont calculées pour compenser les variations d'effort afin d'obtenir une sensation d'effort constant au levier pour le pilote. Les pentes sont plus fortes lorsque les efforts à fournir sont plus faibles, tandis que les pentes sont plus faibles lorsque les efforts à fournir sont plus élevés (voir fig.4). The slopes are calculated to compensate for the variations of effort in order to obtain a feeling of constant effort at the lever for the pilot. Slopes are stronger when the forces to be supplied are lower, while the slopes are lower when the forces to be supplied are higher (see fig.4).
Pour le disque (4) de sélection (fig.3), le cercle primitif extérieur correspond au groupe de vitesses cinquième + marche arrière , le cercle primitif central correspond au groupe de vitesses troisième + quatrième , et enfin le cercle primitif intérieur correspond au groupe de vitesses première + seconde . For the selection disc (4) (fig.3), the outer primitive circle corresponds to the fifth + reverse gear group, the central prime circle corresponds to the third + fourth gear group, and finally the inner prime circle corresponds to the group first + second speed.
Pour le disque (4bis) d'enclenchement (fig.4), le cercle primitif extérieur correspond aux rapports seconde + quatrième + marche arrière , le cercle primitif central correspond au point mort, et le cercle primitif intérieur correspond aux vitesses première + troisième + cinquième . For the disc (4a) of interlocking (fig.4), the outer primitive circle corresponds to the second + fourth + reverse ratio, the central prime circle corresponds to the neutral point, and the inner prime circle corresponds to the first + third velocities. fifth.
Des doigts (5 et 5bis) se trouvent à l'intérieur des chemins. Ces doigts (5 et 5bis) sont liés à des culbuteurs (6 et 6bis). Le rôle des culbuteurs (6 et 6bis) est d'amplifier le mouvement induit par le chemin (9 et 9bis) aux doigts(5 et 5bis), afin de le transmettre aux câbles (2 et 2bis). Fingers (5 and 5bis) are inside the paths. These fingers (5 and 5a) are connected to rocker arms (6 and 6a). The role of the rockers (6 and 6bis) is to amplify the movement induced by the path (9 and 9bis) to the fingers (5 and 5bis), in order to transmit it to the cables (2 and 2bis).
Pour chacune des sept positions fixes, les chemins (9 et 9bis) se trouvent sur des cercles primitifs. Selon le cercles primitifs sur lequel les chemins (9 et 9bis) de chaque disque (4 et 4bis) se trouve, l'un ou l'autre rapport est enclenché. Entre les positions fixes les chemins (9 et 9bis) passent d'un cercle primitif à l'autre afin de réaliser le changement de rapport. For each of the seven fixed positions, the paths (9 and 9bis) are on primitive circles. According to the primitive circles on which the paths (9 and 9bis) of each disc (4 and 4bis) are, one or the other ratio is engaged. Between the fixed positions the paths (9 and 9bis) pass from one primitive circle to another in order to realize the change of ratio.
Décomposition étape par étape de la phase passage de seconde en troisième (exemple pour une boîte de vitesse de type BE4 Peugeot, ce modèle n'étant pas limitatif, le dispositif s'adaptant à la plupart des boîtes de vitesses du marché). Decomposition step by step of the passage phase from second to third (example for a gearbox type BE4 Peugeot, this model is not limiting, the device adapting to most gearbox market).
Phase 1 (repère 2, fig3 et fig4) : Première position fixe: la seconde. A l'endroit où se trouvent les doigts (5 et 5bis), le chemin (9) du disque (4) de sélection se trouve sur le cercle primitif intérieur tandis que le chemin (9bis) du disque (4bis) d'enclenchement se trouve sur le cercle primitif extérieur. Le câble (2) de sélection se trouve donc tiré à fond tandis que le câble d'enclenchement (2bis) se trouve poussé à fond. Phase 1 (mark 2, fig3 and fig4): First fixed position: the second. Where the fingers (5 and 5a) are, the path (9) of the selection disc (4) is on the inner pitch circle while the path (9a) of the interlock disc (4a) is found on the outer primitive circle. The selection cable (2) is thus fully pulled while the locking cable (2a) is pushed all the way.
Phase 2: Le conducteur tire sur son levier (1). L'ensemble arbre (3) + disques (4 et 4bis) se met à tourner. Le chemin du disque d'enclenchement (4bis) passe sur le cercle primitif central (fig.4). Le câble d'enclenchement (2bis) est à moitié tiré. La seconde est sortie, on est au point mort (repère 2.1). Phase 2: The driver pulls on his lever (1). The shaft assembly (3) + disks (4 and 4a) starts to rotate. The path of the interlocking disc (4a) passes over the central primitive circle (fig.4). The locking cable (2a) is half-pulled. The second is out, we are in neutral (reference 2.1).
Phase 3: Le chemin du disque de sélection (4) passe également sur le cercle primitif central. On est toujours au point mort (repère 2.2). Phase 3: The path of the selection disc (4) also passes over the central primitive circle. We are still in neutral (reference 2.2).
Phase 4: Le chemin du disque d'enclenchement (4bis) passe sur le cercle primitif intérieur (fig.4). Le câble de sélection (2) est en position mi-tiré et le câble d'enclenchement (2bis) se trouve poussé à fond. On est dans la nouvelle position fixe: la troisième (repère 3). Au même moment, le levier (1) arrive sur sa butée mécanique (8). Phase 4: The path of the interlock disc (4a) passes over the inner pitch circle (fig.4). The selection cable (2) is in the half-pulled position and the locking cable (2a) is pushed fully. We are in the new fixed position: the third (reference 3). At the same time, the lever (1) reaches its mechanical stop (8).
Phase 5: Le conducteur relâche son levier (1) qui revient dans sa position centrale grâce à un ressort et à un système de cliquet (7). Phase 5: The driver releases his lever (1) which returns to its central position through a spring and a ratchet system (7).
