Abstract

A invenção diz respeito a um dispositivo para lubrificar um rolamento de biela (46) em um eixo de manivelas (24) de um motor de combustão interna. O dispositivo possui um pistão (10) com um canal de fluido (12), particularmente um canal de fluido interno de resfriamento de pistão, e um canal de saída (26) em comunicação fluida com o canal de fluido (12). O dispositivo possui uma biela (22), que é conectada ao pistão (10) de maneira articulada, particularmente pivotável, e possui um olhal grande de biela (44) e um canal de conexão (48). O olhal grande de biela (44) é moldado para receber o rolamento de biela (46). O canal de conexão (48) forma a uma conexão fluida entre o canal de saída (26) e o olhal grande de biela (44) de modo que um fluido, particularmente um fluido lubrificante e refrigerador (por exemplo, óleo), possa ser alimentado, ou seja alimentado, a partir canal de fluido (12) ao olhal grande de biela (44) através do canal de saída (26) e o canal de conexão (48). O rolamento de biela (46) pode, assim, ser lubrificado pelo óleo de resfriamento a partir do canal de fluido (12) do pistão (10). Assim, é possível dispensar os furos complexos e que impactam na durabilidade do eixo de manivelas (24) para o fornecimento ao rolamento de biela (46).
