Abstract
"APERFEIçOAMENTO EM RODADO ARTICULADO PARA IMPLEMENTOS AGRìCOLAS". A presente invenção refere-se a um rodado articulado dotado de sistema compensador que mantém o peso do implemento agrícola uniformemente distribuído, mesmo ao passar por qualquer irregularidade do solo, tanto na posição de trabalho como na de transporte. O conjunto do rodado compensador (1) compreende um rodado (2) que está montado no braço (3) através dos garfos (4). O braço (3) articula-se por meio de mancais (31) na braçadeira (5), que por sua vez é fixada ao chassi do implemento. Um cilindro hidráulico (6) é responsável pela articulação do rodado (2) em relação ao chassi. Para a alteração de posição do implemento para o seu transporte, o cilindro (6) deve ser acionado, projetando a sua haste e fazendo rotacionar o conjunto do rodado (1) em relação ao chassi. O sistema de compensação é constituído pelo cilindro hidráulico (6) dotado de pinos laterais (61) que giram no interior dos mancais flangeados (7 e 7A), garantindo assim a axialidade automática do seu funcionamento. Os mancais flangeados (7 e 7A) são aparafusados em torno dos rasgos (51) da braçadeira (5). A haste do cilindro hidráulico (6) possui um olhal extremo (62) que mancaliza o pino de articulação (8) traspassando um suporte (9). Esse suporte (9) é articulado nas abas (32) do braço (3) através do pino (10). O suporte (9) possui um terceiro ponto de articulação com a haste vertical (11) através de um pino transversal fixo (111) posicionado em seu topo. Essa haste (11) é envolvida por uma capa (12) que é montada no interior de uma caixa cilíndrica (33) solidária ao braço do rodado (3). A capa (12) possui uma cabeça (121) que apoia o suporte (9). Dois segmentos de mola de compressão (13 e 13A) são montados em torno da capa (12), sendo o segmento superior (13) posicionado entre a cabeça da capa (121) e o topo da caixa (33), enquanto que o segmento inferior da mola (13A) é posicionado entre o topo da caixa (33) e uma arruela mantida solidária no final da capa (12) por meio de um pino."ARTICULATED ROAD IMPROVEMENT FOR AGRICULTURAL IMPLEMENTS". The present invention relates to an articulated wheel equipped with a compensating system that maintains the weight of the farm implement evenly distributed, even when passing through any unevenness of the ground in both the working and transport position. The compensating wheel assembly (1) comprises a wheel (2) which is mounted on the arm (3) through the forks (4). The arm (3) is hinged by means of bearings (31) in the clamp (5), which is in turn fixed to the implement chassis. A hydraulic cylinder (6) is responsible for articulating the wheelset (2) with respect to the chassis. To change the position of the implement for transport, the cylinder (6) must be driven by projecting its rod and rotating the wheel assembly (1) relative to the chassis. The compensation system consists of the hydraulic cylinder (6) with side pins (61) that rotate inside the flanged bearings (7 and 7A), thus ensuring the automatic axiality of its operation. Flanged bearings (7 and 7A) are screwed around the slots (51) of the clamp (5). The hydraulic cylinder rod (6) has an end eye (62) that biases the pivot pin (8) through a support (9). This bracket (9) is hinged to the tabs (32) of the arm (3) through the pin (10). The support (9) has a third pivot point with the vertical rod (11) through a fixed transverse pin (111) positioned at its top. This rod (11) is surrounded by a cap (12) which is mounted within a cylindrical housing (33) integral with the wheel arm (3). The cap (12) has a head (121) supporting the support (9). Two compression spring segments (13 and 13A) are mounted around the cap (12), the upper segment (13) being positioned between the cap head (121) and the top of the casing (33), while the segment The lower spring (13A) is positioned between the top of the housing (33) and a washer held solidly at the end of the cover (12) by means of a pin.
