Title (EN) CONTROLLED FORCE ACTUATOR SYSTEM
(FR) SYSTEME DE COMMANDE DU DECLENCHEMENT D'UNE FORCE
Abstract:
(EN) A controlled force actuating system having a positive Belleville spring (Bp) and a negative Belleville spring (Bn) arranged in series between a load member and a reaction member. The positive Belleville spring (Bp) is initially in a relaxed condition and the negative Belleville spring (Bn) being initially in a loaded energy storing condition. A movable control device (24) engages at least the negative Belleville spring so that movement of the control device releases stored energy from the negative Belleville spring to the positive Belleville spring. The combined energy stored in both the positive and negative Belleville springs is applied between the reaction member and the load member. The Belleville springs may be designed so that the rate of energy release from the negative Belleville is substantially the same as, less than, or greater than the rate of energy storage by the positive Belleville spring, depending on whether the application of the system is served by a minimal control force to move the control device, a control force that may be removed after the application of force between the reaction member and the load member, such as in an automotive clutch, or a control force that must be exerted to maintain that application of force, such as in a friction brake.
(FR) Système servant à commander le déclenchement d'une force et possédant un ressort Belleville positif (Bp) et un ressort Belleville négatif (Bn) disposés en série entre un élément de charge et un élément de réaction. Le ressort Belleville positif (Bp) est initialement dans un état de relâchement et le ressort Belleville négatif (Bn) est initialement dans un état chargé d'accumulation d'énergie. Un dispositif de commande mobile (24) vient en contact au moins avec le ressort Belleville négatif, de telle sorte que le déplacement de ce dispositif de commande libère l'énergie accumulée depuis le ressort Belleville négatif vers le ressort Belleville positif. La combinaison d'énergie accumulée dans les ressorts Belleville positif et négatif à la fois est appliquée entre l'élément de réaction et l'élément de charge. Ces ressorts Belleville peuvent être conçus de telle manière que le taux d'énergie libérée du ressort négatif est sensiblement égal, inférieur ou supérieur au taux de l'énergie accumulée par le ressort positif, ceci étant fonction du fait que l'application du système est ou non servie par une force de commande minimum pour déplacer le dispositif de commande, force de commande pouvant être supprimée après l'application d'une force entre l'élément de réaction et l'élément de charge, comme dans un embrayage automobile, ou une force de commande devant être exercée afin de conserver cette application de force, comme dans un frein à friction.
