Title (EN) MECHANISM FOR EQUALIZING THE WEIGHT OF MULTIPLE CHASSIS FORMING AGRICULTURAL MACHINES AND IMPLEMENTS
(FR) MÉCANISME D’ÉGALISATION DU POIDS DES MULTIPLES CHÂSSIS COMPRIS DANS DES MACHINES ET DES OUTILS AGRICOLES

Abstract:
(EN) The invention relates to a particular embodiment of a mechanism for equalizing the weight of multiple chassis forming agricultural machines and implements, equalizing the weight of a heavier chassis relative to another lighter chassis, guaranteeing a uniform distribution of the weight of the equipment over the wheelsets thereof and allowing perfect, uniform following of the unevenness of the ground. The invention is characterized by the appropriate use of pneumatic springs (1) installed in an inclined position (2) on fastening supports (3) and (4) specific, respectively, to the heavier chassis (5) and to the lighter chassis (6), said springs (1) having the technical feature whereby, when they are actuated pneumatically, they exert a force between the chassis (5) and (6), on which they are interlinked, and transfer, by reaction, the weight of the heavier chassis (6) to the lighter chassis (5), thereby equalizing the weight between both chassis and the weight of the equipment over the wheels of the implement; said springs (1) being able to work independently, interdependently, as a closed system or, also, as an active system.
(FR) L'invention concerne une modalité particulière d’un mécanisme d’égalisation du poids de multiples châssis compris dans des machines et des outils agricoles, égalisant le poids d’un châssis plus lourd par rapport à celui d’un autre plus léger, garantissant une distribution uniforme du poids de l’équipement sur ses roulements et permettant d’obtenir une adaptation parfaite et uniforme aux dénivellements du sol. L'invention se caractérise par l’utilisation appropriée de ressorts pneumatiques (1) installés de manière inclinée (2) par l'intermédiaire de supports de fixation spécifiques (3) et (4), respectivement, sur le châssis plus lourd (5) et sur le châssis plus léger (6), lesdits ressorts (1) présentant la caractéristiques technique, lors de leur actionnement pneumatique, d’exercer une force entre les châssis (5) et (6), lesquels sont reliés, et de transférer par réaction le poids du plus lourd (6) vers le plus léger (5), égalisant le poids entre ces deux éléments et le poids de l’équipement sur les roues de l’outil, lesdits ressorts (1) pouvant agir de manière indépendante, de manière liée, comme système fermé ou encore comme système actif.
(PT) O invento trata de peculiar modalidade de mecanismo para equalização do peso de múltiplos chassis integrantes de máquinas e implementos agrícolas, equalizando o peso de um chassi mais pesado para o outro de menor peso, garantindo uma distribuição uniforme do peso do equipamento sobre os seus rodados e proporcionando uma perfeita e uniforme copiagem dos desníveis do solo. O invento caracteriza-se pela utilização apropriada de molas pneumáticas (1), instaladas de forma inclinada (2), por intermédio de suportes de fixação específicos (3) e (4), respectivamente, ao chassi de maior peso (5) e ao chassi de menor peso (6), sendo que ditas molas (1) apresentam a característica técnica de, ao serem acionadas pneumaticamente, exercerem força entre os chassis (5) e (6), nos quais estão interligadas, e transferirem por reação o peso do de maior peso (6) para o de menor peso (5), equalizando o peso entre ambos e o peso do equipamento sobre as rodas do implemento; sendo que ditas molas (1) poderão trabalhar de forma independente, interligadas, como sistema fechado ou, ainda, como sistema ativo.
