Title (EN) ARRANGEMENT FOR SEMI-ACTIVE OR ACTIVE CONTROL OF DAMPING MEMBERS IN A VEHICLE SUSPENSION SYSTEM
(FR) AGENCEMENT DE COMMANDE SEMI ACTIVE OU ACTIVE D'ELEMENTS D'AMORTISSEMENT DANS LE SYSTEME DE SUSPENSION D'UN VEHICULE
Abstract:
(EN) In a vehicle suspension system, there is an arrangement for controlling damping members as a function of the movement between an undamped and damped mass. For the purpose of obtaining a position indicator (9) which is simple and takes up little space between the undamped and damped mass, use is made of a rotating optical pulse transmitter (24) which is coupled to a spring-loaded (23) wire pully (20). The wire pulley (20) has a wire (10) wound round it, which can be drawn out counter to the action of the spring (23) and coupled via coupling members (11, 12) to the second mass. This simple construction permits a protected position of the pulse transmitter itself and simple assembly on different types of spring systems.
(FR) Dans le système de suspension d'un véhicule se trouve un agencement permettant de commander les éléments d'amortissement, en fonction du mouvement entre une masse non amortie et une masse amortie. Afin de réaliser un indicateur de position (9) simple et prenant peu d'espace entre la masse non amortie et la masse amortie, on utilise un émetteur (24) d'impulsions optiques rotatif, lequel est couplé à une poulie à fil métallique (20) à ressort (23). Autour de la poulie (20) est enroulé un fil métallique (10) pouvant être déroulé contre l'action du ressort (3) et couplé par l'intermédiaire d'éléments d'accouplement (11, 12) à la seconde masse. Cette construction simple permet d'obtenir une position protégée de l'émetteur d'impulsions proprement dit, et un montage simple sur différents types de systèmes à ressort.
