Claims (3)

  1. Elément de tension pour le réglage de la force de freinage dans un amortisseur d'oscillations, où l'élément de tension (100) est monté centralement sur un joint d'oscillation (B) pour exercer une force sur un agencement de freinage (50) de manière à obtenir un amortissement des oscillations, où l'élément de tension (100) comprend un axe (110) servant à la suspension d'un accessoire (4) à soumettre à l'amortissement des oscillations, un manchon (130) déplaçable le long d'un épaulement (111) sur l'axe (110) pour activer l'agencement de freinage (50), une vis d'ajustement (140) désignée pour exercer une force de déplacement axiale sur le manchon (130) via un ensemble à ressort (143) et un écrou (160) pour ajuster la force de serrage de la vis d'ajustement (140),
    caractérisé en ce que l'axe (110) comprend un trou central circulaire (120) qui devient un trou carré (122) à la partie d'extrémité arrière de l'axe (110), et le fût (145) de la vis (140) comprend un filetage externe (146) pour la mise en prise avec l'écrou (160), et la pointe (147) de la vis (140) présente une section transversale hexagonale et a des dimensions plus petites que le fût (145) de la vis de sorte que l'écrou (160) peut être appliqué au filetage de vis (146), et l'élément de tension (100) comprend en outre un élément de verrouillage (170) comprenant un trou hexagonal (171) qui coopère avec la pointe hexagonale (147) de la vis (140), et l'élément de verrouillage (170) ainsi que l'écrou (160) ont un contour extérieur carré qui coopère avec le trou carré (122) de sorte que le mouvement de rotation de la vis (140) relativement à l'axe (110) est éliminé.
  2. Elément de tension selon la revendication 1, caractérisé en ce qu'un élément d'arrêt (180) est désigné pour limiter le mouvement axial de l'élément de verrouillage (170).
  3. Elément de tension selon la revendication 1 ou la revendication 2, caractérisé en ce que la pointe (147) de la vis (140) sert de manette lors de l'ajustage de la force de réglage, l'élément de verrouillage (170) et l'élément d'arrêt (180) étant temporairement retirés.
