Abstract

The joint has a spindle centered between two parts of a male endpiece. A movable partial covering element covers a cavity of the male endpiece. A bearing ball is provided between male elements, female elements and encompassing parts. The male elements consist of a spherical end provided with two recessed notches. The bearing ball is not placed on a path of recessed portions of the male elements. The movable partial covering element completely or partially slides in the cavity of the male endpiece.

Description

La présente invention consiste à des améliorations de la demande de brevet Française N° 10/00132 portant sur un nouveau joint mécanique de jonction entre deux axes et permettant de transmettre d'une manière homocinétique ou non 1 selon les variantes un couple d'un axe à un autre The present invention consists of improvements to the French patent application No. 10/00132 relating to a new mechanical joint between two axes and for transmitting in a homokinetic manner or not 1 according to the variants a torque of an axis to another

L'invention de la demande de brevet Française N° 10/00132 permet de réaliser une jonction de type cardan entre deux axes tout en transmettant potentiellement 5 un couple supérieur aux possibilités d'un cardan classique. The invention of the French patent application No. 10/00132 allows a junction of the cardan type between two axes while potentially transmitting a torque greater than the possibilities of a conventional cardan.

La présente invention porte sur 3 améliorations : The present invention relates to 3 improvements:

Amélioration N°1 : Ajout d'une liaison pivot ou rotule centrée entre les deux 10 parties d'embout male du joint de cardan sphérique double, à allongement ou non. (Fig 1 et 2) La rotule ou le pivot, partie male à extrémité sphérique pouvant pivoter dans la partie opposée femelle creuse de forme sphérique de diamètre sensiblement identique. Cette liaison entre les deux embouts males du joint double pourra être 15 rajoutée aux embouts (soudage, vissage, emboitement) ou faire partie intégrante de ceux-ci. Le centre de cette liaison est positionné sur le point d'intersection formé par les 2 axes des embouts males et à égale distance des centres des boules des embouts males. Cette amélioration permet de garantir une liaison homocinétique entre deux axes 20 en réduisant le nombre de paliers nécessaires et en concentrant la liaison pivot ou rotule à l'intérieur du joint. La liaison rotule ou pivot entre les éléments males peut être utilisée avec le joint sphérique double sans allongement, ce qui permet de garantir la transmission homocinétique d'un couple entre deux axes formant un angle fixe ou avec le 25 joint sphérique double à allongement, ce qui permet de garantir la transmission homocinétique d'un couple entre deux axes formant un angle variable. Improvement No. 1: Addition of a pivot connection or ball joint centered between the two parts of the male end of the double spherical universal joint, with elongation or not. (Fig 1 and 2) The ball or the pivot, spherical end male portion being pivotable in the hollow female opposite portion of spherical shape of substantially identical diameter. This connection between the two male ends of the double seal may be added to the end pieces (welding, screwing, interlocking) or be an integral part thereof. The center of this link is positioned on the point of intersection formed by the 2 axes of the male end and equidistant from the centers of the balls of the male end. This improvement ensures a homokinetic connection between two axes 20 by reducing the number of bearings required and concentrating the pivot connection or ball joint inside the joint. The ball joint or pivot between the male elements can be used with the double spherical joint without elongation, which makes it possible to guarantee the homokinetic transmission of a torque between two axes forming a fixed angle or with the double elongated spherical joint. which makes it possible to guarantee the homokinetic transmission of a torque between two axes forming a variable angle.

Amélioration N°2 : Ajout d'un élément mobile de recouvrement partiel de la cavité de l'élément male. L'élément male du joint peut être constitué d'une 30 extrémité sphérique comportant deux encoches évidées. Cet élément mobile glisse et remplit de manière complète ou non la moitié de ces cavités. Ses extrémités peuvent être de forme sphérique creuse afin d'épouser la forme des billes de jonction ou de forme cylindrique creux si les éléments de jonction sont de forme cylindrique. Cet ajout nécessite que la queue d'axe soit ajourée dans le 35 prolongement des cavités selon une section sensiblement identique à la section de l'élément de recouvrement. Cet élément peut être constitué de plusieurs éléments mais ne doit pas dépasser du volume de la sphère de l'élément male afin de permettre le glissement de l'élément femelle sur l'élément male. Cette amélioration permet de réduire les frottements du joint occasionné dans un 40 milieu liquide, d'augmenter l'étanchéité du joint, d'augmenter la sécurité du joint en réduisant les possibilités de pinçage et d'accrochage. 45 2955160 -2- Improvement No. 2: Addition of a movable element for partially covering the cavity of the male element. The male element of the seal may consist of a spherical end having two recessed notches. This mobile element slides and completly fills or not half of these cavities. Its ends may be hollow spherical in order to conform to the shape of the junction balls or hollow cylindrical if the connecting elements are cylindrical. This addition requires that the shaft tail is perforated in the extension of the cavities in a section substantially identical to the section of the covering element. This element may consist of several elements but must not exceed the volume of the sphere of the male element to allow the sliding of the female element on the male element. This improvement makes it possible to reduce the friction of the seal caused in a liquid medium, to increase the tightness of the seal, to increase the safety of the seal by reducing the possibilities of clamping and snagging. 45 2955160 -2-

Amélioration N°3 : Ajout de billes de roulement entre les parties males, femelles et des parties englobantes. Les billes ne doivent pas se trouver sur la trajectoire 5 des parties évidées des éléments males. Cette amélioration permet de réduire les frottements. 10 15 20 25 30 35 40 45 50 Improvement # 3: Addition of rolling balls between the males, females and alligator parts. The beads should not be in the path of the recessed portions of the male members. This improvement reduces friction. 10 15 20 25 30 35 40 45 50
