Definitions

  • the spring element may comprise a leaf spring.
  • the leaf spring can be shaped so that it provides both the radial spring force and the tangential spring force of the spring element.
  • the bending elastic deformation of the beam is thus realized by a leaf spring.
  • the beam may also be formed by a bent wire, the pressure piece preferably forming part of the bent wire.
  • the pressure body is integrally formed on the spring element. Spring element and pressure body thus form a single piece that can be inserted in an assembly step in the recess of the toothing of the first coupling part.
  • the spring element has a holding wing, which serves for the axial fixing of the spring element to the first coupling part.
  • the retaining wing helps to avoid that when telescoping the teeth of the coupling parts, the spring element and, as far as the one-piece design is based, the pressure body is axially displaced from the desired position.
  • FIG. 5 shows the spring element 30 and the pressure body 40 formed thereon as well as a detail of the internal toothing 11 of the first coupling part 10 in plan view. It can be seen that leaf spring vanes 32a, 32b respectively increase in width from their end 33a, 33b in the direction of the central axis 31 of the spring element 30.
  • An end face 42 of the pressure body 40 is formed with curves or insertion bevels, which facilitate an axial telescoping of the teeth 1 1, 21.

Abstract

L'invention concerne un dispositif d'accouplement (1) destiné à transmettre un mouvement de rotation et doté d'une première partie d'accouplement (10) comprenant une denture (11), d'une seconde partie d'accouplement (20) disposée de manière coaxiale et comprenant une autre denture (21) coopérant avec la denture (11) de la première partie d'accouplement (10), d'au moins un élément à ressort (30) destiné à être mis en tension entre les deux parties d'accouplement (20, 23) dans la direction périphérique, et d'un corps de pression (40) formant un clavetage avec une face de dent (24) d'au moins une dent (22) de la denture (21) de la seconde partie d'accouplement (20). Le corps de pression (40) exerce une pression contre la face de dent (24) avec une force radiale FR de l'élément à ressort (30) agissant dans une direction radiale et produit alors une force de tension FU agissant dans la direction périphérique. Le dispositif d'accouplement (1) se caractérise en ce que l'élément à ressort (30) détermine la position du corps de pression (40) dans la direction périphérique.
