Definitions

  • L is the overall length of the undeformed element.
  • the range of adjustment of the point D may be provided, e.g. as indicated from E to E 1 .
  • the point may actually be movable on a straight line as indicated; this approximates sufficiently closely to the theoretical path of movement to operate in the required manner.
  • Linear movement is readily provided, e.g. by a fluid pressure piston and cylinder device as illustrated at 22 in Figure 1, or by an arrangement of a screw and nut driven by an electric motor.

Abstract

Un ressort (23) en forme de croissant possède des bords arqués de sorte que lorsqu'il prend une position courbée, il crée une force sensiblement constante empêchant ses extrémités de se rapprocher l'une de l'autre. Ledit ressort (23) peut s'utiliser dans la suspension d'un véhicule et conjointement avec un dispositif (22) destiné à faire varier la géométrie de la suspension et à adapter celle-ci au chargement du véhicule et aux conditions dynamiques de celui-ci.
