CA 2247059

In an outboard marine drive including a vertically oriented engine, a disk member is attached to a lower end of the crankshaft of the engine, and the upperend of the drive shaft is disposed coaxially with respect to the crankshaft and at a prescribed distance from the disk member so that a direct coupling member and a centrifugal clutch device may be interchangeably installed between them. The disk member is provided with axial holes for either pivotally supporting clutch shoes or fixedly attaching the upper end of the direct coupling member. The lower end of the direct coupling member and the clutch drum of the centrifugal clutch device are provided with an identical coupling arrangement for coupling with an upper end of the drive shaft.

Dans une commande de moteur marin amovible vertical, un disque est fixé à l'extrémité inférieure d'un vilebrequin du moteur, et l'extrémité supérieure de l'arbre d'entraînement, placée dans le même axe que le vilebrequin, se situe à une distance déterminée du disque, ce qui permet d'installer entre les deux, de façon interchangeable, un élément d'accouplement direct et un dispositif d'embrayage centrifuge. Le disque présente des trous axiaux permettant soit de soutenir par une articulation des mâchoires d'embrayage, soit de fixer en l'immobilisant l'extrémité supérieure de l'élément d'accouplement direct. L'extrémité inférieure de l'accouplement direct et le tambour d'embrayage du dispositif d'embrayage centrifuge sont munis d'un assemblage d'accouplement identique qui leur permet d'être rattachés à une extrémité supérieure de l'arbre d'entraînement.
