ABSTRACT:
The invention relates to a device for coupling two shafts that are intended to rotate in the continuation of one another with respect to a casing (4). A dog clutch couples the two shafts.The device comprises clutch-release means allowing the dog clutch (9) to be uncoupled. According to the invention, the clutch-release means comprise a ramp (17) secured to the casing (4), the ramp (17) having a helical shape around the axis (1), a flat disk (19) secured to the first shaft (3) the plane of which is more or less perpendicular to the axis (1), an element (20) intended to roll between the ramp (17) and the disk (19) so as to cause a translational movement of the first shaft (3) with respect to the casing (4) more or less along the axis (1), the translational movement allowing the dog clutch (9) to be uncoupled.The specific structure of the clutch-release means enables the shafts to be uncoupled while they are in rotation.
