Abstract

Dans un système de suspension pneumatique d'un véhicule, la hauteur du plateau du véhicule est commandée au cours du fonctionnement grâce à des soupapes de commande de la hauteur (6, 7). Pour faciliter le chargement, la hauteur peut être modifiée par un utilisateur en passant outre lesdites soupapes (6, 7) en actionnant une soupape de sélectionnement (8). La hauteur peut alors être réglée au moyen d'une soupape d'élévation/abaissement (5). Au cas où l'utilisateur ne remettrait pas à leur état normal la soupape de sélectionneemnt (8) et/ou la soupape d'élévation/abaissement (5), la soupape de sélectionnement (8) est ramenée à sa position normale par une canalisation de pilotage (43) reliée à une canalisation de freinage de service, de sorte que le véhicule retrouve sa hauteur normale de circulation lors de la première application des freins. On peut également faire en sorte que la soupape soit commandée par un solénoïde relié au circuit d'éclairage de freinage, de sorte que la canalisation du freinage de service n'est pas affectée. Dans une autre réalisation la hauteur du système de suspension est réglée par deux soupapes à ressort commandées manuellement. Dans ce cas également, une soupape de sélectionnement reprend un état dans lequel la hauteur de circulation est atteinte lors de l'application du freinage de service.
