Abstract

Le mécanisme de transmission de mouvements axiaux et rotatifs entre deux parties (8, 9) d'une tige d'axes décalés comporte un ensemble mobile constitué d'une pièce de liaison (19) comportant deux éléments (23, 30) dont au moins un est élastique formant avec le corps central rigide (22) de cette pièce de liaison (19) deux paliers (24, 25; 31, 32). Chacune des parties de ladite tige comporte une extrémité portant un pignon (13, 17) et étant agencées pour être pivotée dans l'un desdits deux paliers. Dans ce mécanisme l'un des éléments (30) présente un prolongement de verrouillage (35) terminé par un crochet (36) coopérant avec une formation de verrouillage (37) du corps (22) de ladite pièce de liaison (19). Lorsque ce crochet (36) est engagé dans la formation de verrouillage (37) le ou les deux éléments élastiques (23, 30) sont bloqués en position de service ne pouvant plus s'écarter du corps (22) de la pièce de liaison (19).

Figure imgaf001
The mechanism for transmitting axial and rotary movements between two parts (8, 9) of a staggered shaft comprises a movable assembly consisting of a connecting piece (19) comprising two elements (23, 30) of which at least one is elastic forming with the rigid central body (22) of this connecting piece (19) two bearings (24, 25; 31, 32). Each of the parts of said rod has an end bearing a pinion (13, 17) and being arranged to be pivoted in one of said two bearings. In this mechanism one of the elements (30) has a locking extension (35) terminated by a hook (36) cooperating with a locking formation (37) of the body (22) of said connecting piece (19). When this hook (36) is engaged in the locking formation (37), the two elastic elements (23, 30) are locked in the operating position and can no longer deviate from the body (22) of the connecting piece ( 19).
