Abstract

Titre de l’invention : Embrayage humide La présente invention concerne un embrayage humide (1) pour système de transmission de couple, comprenant au moins un embrayage multidisques (E1, E2, K0), au moins un piston d’actionnement (30) dudit embrayage multidisques (E1, E2, K0) et au moins une cavité (25) destinée à contenir un lubrifiant, la cavité (25) étant délimitée au moins par un fond, une paroi périphérique externe (38) et le piston d’actionnement (30). Selon l’invention, la paroi périphérique externe (38) et/ou le piston d’actionnement (30) comprend au moins un moyen de rétention (56, 58) du lubrifiant, le moyen de rétention (56, 58) étant formé sur la paroi périphérique externe (38) de la cavité (25) et/ou sur le piston d’actionnement (30). Figure de l’abrégé : Figure 1Title of the invention: Wet clutch The present invention relates to a wet clutch (1) for a torque transmission system, comprising at least one multi-plate clutch (E1, E2, K0), at least one actuating piston (30) of said multi-disc clutch (E1, E2, K0) and at least one cavity (25) intended to contain a lubricant, the cavity (25) being delimited at least by a bottom, an external peripheral wall (38) and the actuating piston ( 30). According to the invention, the external peripheral wall (38) and/or the actuating piston (30) comprises at least one lubricant retention means (56, 58), the retention means (56, 58) being formed on the outer peripheral wall (38) of the cavity (25) and/or on the actuating piston (30).
