Title
(EN) CONSTANT VELOCITY JOINT
(FR) JOINT HOMOCINÉTIQUE
Abstract
(EN)
The constant velocity joint consists of the input shaft (1), the output shaft (2), three spherical left arms (4L), three spherical right arms (4P), and the stabilising mechanism (3). The stabilising mechanism (3) is made up of three stabilising segments (3.1), (3.2), and (3.3). Stabilising segments have limited all degrees of freedom except the possibility of partial rotation around the axis of the stabilising mechanism (3). Each stabilising segment (3.1), (3.2) or (3.3) has one spherical arm (4L) and one spherical arm (4P) attached by means of a bolt (6), two groups of rolling elements (8), and a distance ring (12) in away they can only rotate around the axis of the bolt (6). The input shaft (1) carries on his body three arms (1.1), (1.2), and (1.3). The output shaft (2) carries on his body three arms (2.1), (2.2), and (2.3). In arms of both shafts there are outer rolling paths created for groups of rolling elements (9), which perform the function of radial-axial bearings. The input shaft (1) is attached to the set of the stabilising mechanism and spherical arms through three bolts (7), which pass through radial-axial bearings in arms of the shaft (1.1), (1.2), and (1.3), and are attached into spurs on spherical arms (4P). The output shaft is connected in the same way.

L'invention concerne un joint homocinétique composé de l'arbre d'entrée (&), de l'arbre de sortie (2), de trois bras gauches sphériques (4L), de trois bras droits sphériques (4P) et du mécanisme stabilisateur (3). Le mécanisme stabilisateur (3) est composé de trois segments stabilisateurs (3.1), (3.2) et (3.3). Les segments stabilisateurs ont des degrés de liberté limités, à l'exception de la possibilité de rotation partielle autour de l'axe du mécanisme stabilisateur (3). Chaque segment stabilisateur (3.1), (3.2) ou (3.3) comprend un bras sphérique (4L) et un bras sphérique (4R) qui sont attachés au moyen d'une vis (6), deux groupes d'éléments roulants (8) et une bague entretoise (12) de telle sorte qu'ils peuvent seulement tourner autour de l'axe de la vis (6). L'arbre d'entrée (1) porte sur son corps trois bras (1.1), (1.2) et (1.3). L'arbre de sortie (2) porte sur son corps trois bras (2.1), (2.2) et (2.3). Dans les bras des deux arbres se trouvent des pistes de roulement extérieures créées pour des groupes d'éléments roulants (9) qui assurent la fonction de roulements radiaux-axiaux. L'arbre d'entrée (1) est attaché au jeu du mécanisme stabilisateur et des bras sphériques au moyen de trois vis (7) qui passent à travers les roulements radiaux-axiaux situés dans les bras de l'arbre (1.1), (1.2) et (1.3) et qui sont attachées dans des griffes des bras sphériques (4P). L'arbre de sortie est monté de la même façon.
