Description

CAVALIER DE COURROIE A kILLONS POUSSANT
La présente invention se rapporte à une transmission à courroie et poulies fonctionnant sans lubrification et pour laquelle une poulie au moins est munie d'une gorge variable constituant ainsi une trains mission connue sous le nom de variateur continu de vitesse
L'invention porte plus particulièrement sur les "cavaliers" équipant une courroie, de type connu, sous la dénomination de courroie à mail lons poussants.PUSHING KILLON BELT RIDER
The present invention relates to a belt and pulley transmission operating without lubrication and for which at least one pulley is provided with a variable groove thus constituting a mission train known as a continuous speed variator
The invention relates more particularly to the "riders" equipping a belt, of known type, under the name of belt with pushing mail.

Les qualités principales recherchées pour les trnasmissions de ce type sont : un rendement élevé, une longévité importante, un encombrement et un poids réduits.The main qualities sought for trnasmissions of this type are: high efficiency, long service life, space and reduced weight.

Les courroies à maillonsfpoussants sont généralement constituées d'une lanière centrale, réalisée a' l'aide d'un ou plusieurs éléments, sur laquelle peuvent circuler des cavaliers ou maillons.The push-link belts generally consist of a central strap, made using one or more elements, on which jumpers or links can circulate.

La particularité des courroies à maillons poussants est la transmission de la puissance entre la poulie motrice (1) et la poulie réceptrice (2) par l'intermédiaire du brin poussé (4), comme cela est représenté figure 2. Ceci est en opposition avec les courroies tirantes, pour lesquelles le transport de la puissance s'effectue par traction sur l'un des brins (3) de la courroie1 l'importance de la puissance transmise étant fonction de la différence de tension existant entre les deux brins, comme cela est représenté figure 1 (fonctionnement d'une courroie).The peculiarity of push-link belts is the transmission of power between the driving pulley (1) and the receiving pulley (2) via the pushed strand (4), as shown in Figure 2. This is in opposition with the pulling belts, for which the power is transported by traction on one of the strands (3) of the belt1 the importance of the transmitted power being a function of the tension difference existing between the two strands, like this is shown in Figure 1 (operation of a belt).

Dans le cas d'une courroie à maillons poussants, le passage de la puissance s'effectue par la transmission d'un effort de compression sur les maillons (5) formant une colonne rigide entre les deux poulies.In the case of a push-link belt, the passage of power is effected by the transmission of a compressive force on the links (5) forming a rigid column between the two pulleys.

Les maillons sont guidés par une lanigère ou courroie plate, devant être suffisamment rigide pour remplir correctement la fonction guidage, mais qui doit également accepter la prise de rayons de courbure compa- tible avec la fonction (voir figure 2 o principe de courroie à maillons poussants). The links are guided by a lanigère or flat belt, which must be rigid enough to correctly fulfill the guiding function, but which must also accept the taking of radii of curvature compatible with the function (see figure 2 o principle of pushing belt ).

En fonctionnement, il existe un déplacement relatif entre la lanière et les cavaliers qui entraine une perte de rendement ainsi qu'une usure de la courroie
De plus, des cavaliers non symétriques par rapport à un plan perpendiculaire au sens du mouvement, occasionnent des surtensions sur un côté de la lanière et déséquilibrent le mouvement général de la courroie, il faut alors avoir recours à un guidage précis des cavaliers les uns par rapport aux autres, en plus du guidage sur la lanière
Le cavalier, objet de la présente invention, apporte par sa géométrie des solutions permettant de limiter le déplacement relatif lanièrecavaliers et autorise, en raison de la symétrie par rapport au plan perpendiculaire au mouvement, une possibilité de montage alterné minimisant ainsi les exigences dans le domaine des tolérances dimensionnelles et géométriques, permettant en particulier la réalisation par moulage desdits cavaliers
Le but de la présente invention est de proposer des cavaliers montés et fonctionnant sur une lanière afin de constituer une courroie à maillons poussants, chaque cavaliers comprenant une âme et deux ailes d'accrochage symétriques. Chaque cavalier est d'épaisseur constante et comporte deux plans de détalonnage symétriques de façon que les arêtes de contact desdits plans de détalonnage soient situées dans une zone voisine du plan médian des encoches, ledit plan médian étant audessus desdites arêtes de contact.In operation, there is a relative movement between the strap and the jumpers which results in a loss of performance and wear of the belt.
In addition, jumpers that are not symmetrical with respect to a plane perpendicular to the direction of movement, cause overvoltage on one side of the strap and unbalance the general movement of the belt, it is then necessary to resort to precise guidance of the jumpers compared to others, in addition to the guide on the strap
The rider, object of the present invention, provides, by its geometry, solutions making it possible to limit the relative displacement of the strap lanes and allows, due to the symmetry with respect to the plane perpendicular to the movement, a possibility of alternate mounting thus minimizing the requirements in the field. dimensional and geometric tolerances, in particular allowing the molding of said jumpers
The object of the present invention is to provide jumpers mounted and operating on a strap in order to constitute a push-link belt, each jumper comprising a core and two symmetrical attachment wings. Each jumper is of constant thickness and has two symmetrical relief planes so that the contact edges of said relief plans are located in an area close to the median plane of the notches, said median plane being above said contact edges.

De plus, chaque face latérale du cavalier selon l'invention, est une surface bombée convexe définie par une partie cylindrique passant par les arêtes d'extrémité de telle manière que le plan tangent à cette partie cylindrique et parallèle au plan passant par lesdites arêtes, soit tangent suivant une ligne, qui se trouve sensiblement dans le plan des arêtes de contact.In addition, each lateral face of the jumper according to the invention is a convex curved surface defined by a cylindrical part passing through the end edges so that the plane tangent to this cylindrical part and parallel to the plane passing through said edges, or tangent along a line, which lies substantially in the plane of the contact edges.

Le cavalier selon l'invention peut également comporter un bombé transversal et un bombé sur la portée. The rider according to the invention may also include a transverse curved and a curved on the span.

Le cavalier (6) est monté sur la lanière (7) par déformation de ladite lanière, comme on le voit sur la figure 3.The jumper (6) is mounted on the strap (7) by deformation of said strap, as seen in FIG. 3.

Les figures 4, 5 et 6 définissent le cavalier 6 selon linventionO
Le cavalier 6 comprend une âme 9 et deux ailes dgaecrochage 8 symétriques par rapport à un plan Wo Le cavalier 6 a une épaisseur constante et comporte deux plans de détalonnage 12 symétriques par rapport à un plan Il. Ces plans de détalonnage ont une orientation définie par l'angle de détalonnage 23. Chaque aile d'accrochage 8 comporte une encoche 18 permettant le montage de la lanière 7. De plus, chaque aile d'accrochage 8 est munie dsun chanfrein d'entrée 14. Le dessus de 17âme 9 est la portée 17 de la lanière 7. Cette portée 17 est munie d'un bombé longitudinal suivant le dessin de la figure 4.Cette portée 17 est menine également d'un bombé transversal suivant le dessin de la figure 5.Figures 4, 5 and 6 define the jumper 6 according to linventionO
The jumper 6 comprises a core 9 and two dgaecrochage wings 8 symmetrical with respect to a plane Wo The jumper 6 has a constant thickness and comprises two offset planes 12 symmetrical with respect to a plane II. These offset planes have an orientation defined by the offset angle 23. Each attachment wing 8 has a notch 18 allowing the mounting of the strap 7. In addition, each attachment wing 8 is provided with an inlet chamfer 14. The top of the core 9 is the span 17 of the strap 7. This span 17 is provided with a longitudinal bulge according to the drawing in FIG. 4. This span 17 is also led by a transverse bulge according to the drawing of the figure 5.

Les plans de détalonnage 12 déterminent avec les faces longitudinales 24 du cavalier 6 des arêtes de contact 13. Ces arêtes de contact 13 sont situées dans une zone voisine du plan médian II-II des encoches 18, ledit plan médian étant au-dessus desdites arêtes de contact i3-
Le cavalier 6 comprend deux faces latérales 16 qui sont munies d'un chanfrein 15. Chaque face latérale 16 symétrique par rapport au plan V V, est constituée par une surface bombée convexe. Cette surface bombée convexe est définie par une partie cylindrique passant par des arêtes 19 et 20, de telle manière qu'un plan 22, tangent à cette partie cylindrique et parallèle au plan 25 passant par les aretes 19 et 20, soit tangent suivant une ligne 21 qui se trouve sensiblement dans le plan des arêtes de contact 13. The offset planes 12 determine with the longitudinal faces 24 of the jumper 6 of the contact edges 13. These contact edges 13 are located in an area close to the median plane II-II of the notches 18, said median plane being above said edges contact i3-
The jumper 6 comprises two lateral faces 16 which are provided with a chamfer 15. Each lateral face 16 symmetrical with respect to the plane VV, is constituted by a convex convex surface. This convex curved surface is defined by a cylindrical part passing through edges 19 and 20, so that a plane 22, tangent to this cylindrical part and parallel to the plane 25 passing through the edges 19 and 20, is tangent along a line 21 which is located substantially in the plane of the contact edges 13.

Dans un autre mode de réalisation, le chanfrein 15 peut être remplacé par une surface bombée convexe constituée par un arrondi ou une portion de cercle joignant les faces latérales 16 du cavalier 6.In another embodiment, the chamfer 15 can be replaced by a convex convex surface constituted by a rounded or a portion of a circle joining the lateral faces 16 of the jumper 6.

Dans un autre mode de réalisation de l'invention, le cavalier représenté sur la figure 7 comporte un pion de centrage 10 à deux têtes hémispheriques et un trou de centrage Il ayant un diamètre identique audit pion 10. Le pion 10 et le trou de centrage sont symétriques par rapport au plan V-V. De ce fait, le pion de centrage 10 d'un cavalier pénètre dans le trou Il correspondant d'un cavalier voisin et ce dispositif interdit à ces deux cavaliers successifs tout déplacement dans un plan parallèle aux faces longitudinales 24 et notamment des mouvements de rotation.In another embodiment of the invention, the jumper shown in FIG. 7 comprises a centering pin 10 with two hemispherical heads and a centering hole II having a diameter identical to said pin 10. The pin 10 and the centering hole are symmetrical with respect to the VV plane. Therefore, the centering pin 10 of a jumper enters the corresponding hole II of a neighboring jumper and this device prevents these two successive jumpers from moving in a plane parallel to the longitudinal faces 24 and in particular rotational movements.

La figure 8 représente un autre mode de réalisation des cavaliers selon l'invention. Dans ce cas, il est réalisé de demi-cavaliers non symétriques 6i et 62, mais dont l'assemblage sur la lanière 7 s'effectue suivant un plan de symétrie qui correspond au plan médian I-I de la figure 5. FIG. 8 represents another embodiment of the jumpers according to the invention. In this case, non-symmetrical half-jumpers 6i and 62 are produced, but the assembly of which on the strap 7 is carried out according to a plane of symmetry which corresponds to the median plane I-I of FIG. 5.
