HYDRAULIC CLUTCH Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: hydraulic clutch has driving clutch member provided with spring-loaded blades, which are mounted for movements in radial direction, and driven clutch member provided with control cam fixed to it in axial direction and for engaging with the blades. Cross-section of the cam has two diametrically opposite arcs of grater radius, which increase with cam length, and two arcs of lesser radius, which is constant over the length of the cam, smoothly conjugated with the grater arcs. Two diametrically opposite projections are provided on inner side of the driven clutch member. The projections are in contact with surfaces of the driving clutch member and arranged from the side of surfaces of the cam made over the arcs of constant radius. Spaces between the clutch members, which are formed by the projections, are cross interconnected via passages provided in the driving clutch member. Diametrically opposite sections of the driving clutch member interposed between the blades are also interconnected via passages. The blades can rotate. EFFECT: enhanced reliability. 5 cl, 8 dwg
