Dans les transmissions automatisées de véhicules automobiles courantes, les changements de rapport de transmission s'effectuent par le moyen d'organes de friction, freins et embrayages, fonctionnant dans l'huile et actionnés par des vérins hydrauliques alimentés par une pompe, antagonistes de ressorts actifs ou de rappel. In automated transmissions of common motor vehicles, the transmission ratio changes are effected by means of friction members, brakes and clutches, operating in the oil and actuated by hydraulic cylinders fed by a pump, antagonists of springs active or recall.
Leur maintien dans un état quelconque, accouplé ou désaccouplé, cause une consommation indésirable d'énergie. Their maintenance in any state, coupled or uncoupled, causes an undesirable consumption of energy.
Il est proposé ici un dispositif de verrouillage combiné à la mise en couvre d'un ressort diaphragme assurant la progressivité et le maintien de l'accouplement. 10 De ce fait l'actionneur, extérieur à l'embrayage n'est sollicité, et donc ne consomme de l'énergie, que pour le changement d'état. It is proposed here a locking device combined with the covering of a diaphragm spring ensuring the progressivity and maintenance of the coupling. As a result, the actuator, external to the clutch, is not loaded, and therefore only consumes energy, for the change of state.
L'application du même principe peut être faite à un embrayage double du genre que ceux utilisés dans les transmissions dans lesquelles le couple passe 15 alternativement d'un arbre récepteur à un autre, le changement de rapport étant effectué en anticipation sur l'arbre libre. The application of the same principle can be made to a double clutch of the kind used in transmissions in which the torque alternately passes from one receiving shaft to another, the gear change being made in anticipation on the free shaft. .
Bien que la justification de l'invention, telle que présentée implique un fonctionnement à sec, son principe peut facilement être transposé à un embrayage 20 fonctionnant dans l'huile mono ou multidisques. Although the justification of the invention as presented involves dry running, its principle can easily be transposed to a clutch operating in mono or multi-disc oil.
Les figures 1 à 6 de la planche 1/1 représentent un embrayage simple ou double, mono disque à verrouillage d'un premier principe. Figures 1 to 6 of the plate 1/1 show a single or double clutch, single locking disc of a first principle.
25 Les figures 7 à 10 de la planche 1/1 représentent un deuxième dispositif de verrouillage. Figures 7 to 10 of Plate 1/1 show a second locking device.
La partie menante, solidaire de l'arbre moteur (2) est constituée du disque-volant (1) à l'intérieur duquel coulisse le disque (7). (1) et (7) sont liés en rotation par 30 les cannelures (8). The driving part, integral with the drive shaft (2) consists of the flying disc (1) inside which slides the disc (7). (1) and (7) are rotatably connected by the splines (8).
La partie menée, solidaire de l'arbre récepteur (6) est constituée du disque (4). (4) et (6) sont liés en rotation par les cannelures (5). Des tiges épaulées (10) sont fixées à travers des alésages parallèles sur le disque (7) au moyen d'écrous tubulaires (11), tandis que de l'autre coté, un empilage est constitué au moyen de deux bagues (12) et (13) serrées par l'écrou (14), pincent la périphérie du ressort diaphragme (20). The driven part, secured to the receiving shaft (6) consists of the disc (4). (4) and (6) are rotatably connected by the splines (5). Stepped stems (10) are fixed through parallel bores on the disc (7) by means of tubular nuts (11), while on the other side a stack is formed by means of two rings (12) and (13) clamped by the nut (14), pinch the periphery of the diaphragm spring (20).
Le ressort à diaphragme (20) comporte des bras radiaux d'égale résistance liés par une couronne extérieure ou intérieure. The diaphragm spring (20) has radial arms of equal strength connected by an outer or inner ring.
La partie intérieure de (20) est insérée dans la gorge de la bague (21) dont le profil intérieur engrène avec un profil conjugué logé à l'extrémité du bras radial d'un certain nombre de basculeurs (22) qui tournent autour des axes (23) portés par les oreilles (25-1) partie du couvercle (25) solidaire du disque volant (1). Les basculeurs (22) portent à l'extrémité de chacun de leurs bras axiaux, disposés symétriquement par rapport à l'axe (23), un axe (26) autour duquel tournent les galets (27). The inner part of (20) is inserted in the groove of the ring (21) whose inner profile meshes with a conjugate profile housed at the end of the radial arm of a number of rockers (22) which rotate around the axes (23) carried by the ears (25-1) part of the cover (25) integral with the flying disc (1). The rockers (22) carry at the end of each of their axial arms, arranged symmetrically with respect to the axis (23), an axis (26) around which the rollers (27) rotate.
20 Lesdits galets engrènent avec les flancs d'une came torique (28), de profil conjugué, issu du fourreau coulissant coaxial à l'arbre moteur (2) et récepteur (6) portant la bague intérieure de la butée tournante (30), la bague extérieure portant l'étrier annulaire de commande (31). Said rollers mesh with the flanks of an O-ring (28), of conjugated profile, coming from the sliding sleeve coaxial with the drive shaft (2) and receiver (6) carrying the inner ring of the rotary stop (30), the outer ring carrying the annular control bracket (31).
25 L'étrier (31) comporte une rainure annulaire sur les flancs de laquelle une fourchette extérieure actionne l'embrayage en déplaçant dans un sens ou dans l'autre la came (28), entrainant les basculeurs (22) jusqu'à leur position auto-verrouillée. The stirrup (31) has an annular groove on the flanks of which an outer fork actuates the clutch by moving the cam (28) in one direction or the other, causing the rockers (22) to reach their position. self-locked.
La configuration représentée sur la figure 1 correspond au non-accouplement. 30 La came (28) est avancée en position intermédiaire sous les basculeurs (22) placés en position neutre, le ressort diaphragme (20) est libre et le disque (4) désaccouplé. The configuration shown in Figure 1 corresponds to the non-coupling. The cam (28) is advanced in the intermediate position under the rockers (22) placed in neutral position, the diaphragm spring (20) is free and the disc (4) uncoupled.
La configuration représentée sur la figure 4 correspond à l'accouplement. La came (28 est reculée, les basculeurs (22) basculent vers l'avant, poussant le ressort (20) vers la gauche, le disque (4) est pressé et donc accouplé. Dans une version voulue par l'inventeur, la figure 1 (partie inférieure) 10 représente également un embrayage double. Un disque de friction (40) lié en rotation à un deuxième arbre récepteur tubulaire (41), est disposé symétriquement par rapport au disque coulissant (40) à l'embrayage simple (7) et pressé contre le disque couvercle (42) fixé sur le disque The configuration shown in Figure 4 corresponds to the coupling. The cam (28 is retracted, the rockers (22) swing forward, pushing the spring (20) to the left, the disk (4) is pressed and thus coupled In a version desired by the inventor, the figure 1 (lower part) 10 also shows a double clutch A friction disc (40) rotatably connected to a second tubular receiving shaft (41) is arranged symmetrically with respect to the sliding disc (40) at the single clutch (7). ) and pressed against the cover disc (42) fixed on the disc
15 volant (1) L'accouplement de l'arbre récepteur (6) est obtenu lorsque la came (28) prend une position arrière, tandis que l'accouplement de l'arbre récepteur (41) est obtenu lorsque la came (28) prend une position avant. Les arbres (6) et (41) sont désaccouplés lorsque la came (28) est en position intermédiaire. Flywheel (1) The coupling of the output shaft (6) is obtained when the cam (28) assumes a rear position, while the coupling of the output shaft (41) is obtained when the cam (28) takes a position before. The shafts (6) and (41) are uncoupled when the cam (28) is in the intermediate position.
En se reportant à la figure 6 de la planche 1/1 est représenté un principe à 25 ressorts précontraints réduisant la course du système de commande. Referring to Figure 6 of Plate 1/1 is shown a preloaded spring principle reducing the stroke of the control system.
Deux ressorts diaphragmes (32) sont maintenus écartés sur leur circonférence intérieure au moyen d'une bague libre (33) tandis qu'ils sont rapprochés sur leur circonférence extérieure au moyen de deux flasques opposés (34) lesquels prennent 30 appui, à l'intérieur sur la bague (35) et à l'extérieur sur les bagues (36) et (37) se substituant à (12) et (43). 20 4 2957125 Les galets (27) peuvent être supprimés et remplacés par un profil équivalent taillé sur le basculeur. Two diaphragm springs (32) are held apart on their inner circumference by means of a free ring (33) while they are brought together on their outer circumference by means of two opposing flanges (34) which bear against each other. inside on the ring (35) and on the outside on the rings (36) and (37) substituting for (12) and (43). The rollers (27) can be removed and replaced by an equivalent profile cut on the rocker.
En se reportant aux figures 7 à 10 de la planche 1/1 on a représenté une 5 variante pour réaliser le verrouillage. Referring to Figures 7 to 10 of the 1/1 board there is shown a variant to achieve the locking.
Le fourreau (38) agissant comme la came (28) porte une gorge de profil tiers de cercle dans laquelle s'insèrent partiellement des billes (39) qui restent prisonnières en permanence des trous réalisés dans la bague coulissante (43) solidaire de la partie 10 intérieure du ressort diaphragme (20). The sheath (38) acting as the cam (28) carries a groove of third circle profile in which partially insert balls (39) which remain permanently captive holes made in the sliding ring (43) secured to the part 10 inside the diaphragm spring (20).
On verrouille l'ensemble de l'embrayage au moyen du mouvement axial de va et vient du fourreau (38) qui entraine l'élément (43) vers l'avant ou vers l'arrière. The clutch assembly is locked by the axial movement back and forth of the sleeve (38) which drives the member (43) forward or backward.
15 Les billes poussées par la force antagoniste du ressort diaphragme (20 bis), dans l'une ou l'autre des gorges (45, 46) réalisées sur la bague (47) solidaire du disque volant (1) verrouillent dans leur position extrême la bague (43). The balls pushed by the opposing force of the diaphragm spring (20a), in one or other of the grooves (45, 46) formed on the ring (47) integral with the flying disc (1) lock in their extreme position. the ring (43).
Compte tenu de la course nécessaire au fonctionnement du mécanisme, le 20 ressort diaphragme (20 bis) constitue un levier réducteur de course. Le ressort à diaphragme (20 bis) prend appui sur un diamètre proche de l'extérieur sur deux bossages en vis-à-vis (44) et (48) solidaires du disque volant (1). Les bras du ressort diaphragme (20 bis) sont d'égale résistance d'où leur forme en losange. In view of the travel required to operate the mechanism, the diaphragm spring (20a) constitutes a race-reducing lever. The diaphragm spring (20a) bears on a diameter close to the outside on two bosses facing each other (44) and (48) integral with the flying disc (1). The arms of the diaphragm spring (20 bis) are of equal strength, hence their diamond shape.
