Abstract

Dispositif pour optimiser le fonctionnement de suspensions pneumatiques de poids lourds. Il est constitué d'un boitier extérieur (1) à l’intérieur duquel sont fixés dans l’ordre de montage un joint d’élasticité (2) reposant sur le bord inférieur du boitier, le disque de base (3), le joint de base (4) et le corps (5). Dans les alésages du corps (5) monté dans le boitier extérieur se trouvent les ressorts hélicoïdaux (6) et les pastilles (7). Le dispositif comporte aussi le couvercle (8) fixé par les vis (13) dans le corps (5). Sur le couvercle (8) est monté une soupape de décharge composée d’un support de soupape (11), un ressort ondulé (10) et un tampon (9) ainsi qu’une électrovanne (12). Le dispositif vise à réduire la pollution par la diminution de la friction entre les roues et le revêtement de la route. Figure pour l’abrégé : Fig. 8Device for optimizing the operation of pneumatic suspensions of heavy goods vehicles. It consists of an outer box (1) inside which are fixed in the order of assembly an elastic seal (2) resting on the lower edge of the box, the base disc (3), the seal base (4) and body (5). In the bores of the body (5) mounted in the outer casing are the coil springs (6) and the pads (7). The device also comprises the cover (8) fixed by the screws (13) in the body (5). On the cover (8) is mounted a relief valve consisting of a valve holder (11), a wave spring (10) and a buffer (9) as well as a solenoid valve (12). The device aims to reduce pollution by reducing the friction between the wheels and the road surface. Figure for the abstract: Fig. 8
