A multidisk oil-bath clutch comprising: a housing mounted to rotate about a longitudinal axis of rotation; at least one hub mounted to rotate about the longitudinal axis of rotation and housed inside and coaxially with the housing; a number of drive disks housed inside the housing and angularly integral with the housing or the hub; a number of driven disks housed inside the housing, alternating with the drive disks, and angularly integral with the hub or the housing; at least one main oil inlet into the housing; and at least one oil outlet from the housing; wherein each drive disk comprises a number of first circulation channels equally spaced about the longitudinal axis of rotation and extending radially from an inner edge of the drive disk to an outer edge of the drive disk; and wherein each driven disk comprises a number of second circulation channels equally spaced about the longitudinal axis of rotation and extending radially from an inner edge of the driven disk to an outer edge of the driven disk; the oil-bath clutch being characterized in that: on each driven disk, the second circulation channels are formed inside the driven disk; and each second circulation channel extends between at least one axial inner opening formed through a lateral wall of the driven disk, close to the inner edge of the driven disk, and one radial outer opening formed through the outer edge of the driven disk so that the second circulation channel ends only at a given distance from the inner edge of the driven disk. a housing mounted to rotate about a longitudinal axis of rotation; at least one hub mounted to rotate about the longitudinal axis of rotation and housed inside and coaxially with the housing; a number of drive disks housed inside the housing and angularly integral with the housing or the hub; a number of driven disks housed inside the housing, alternating with the drive disks, and angularly integral with the hub or the housing; at least one main oil inlet into the housing; and at least one oil outlet from the housing; wherein each drive disk comprises a number of first circulation channels equally spaced about the longitudinal axis of rotation and extending radially from an inner edge of the drive disk to an outer edge of the drive disk; and wherein each driven disk comprises a number of second circulation channels equally spaced about the longitudinal axis of rotation and extending radially from an inner edge of the driven disk to an outer edge of the driven disk; the oil-bath clutch being characterized in that: on each driven disk, the second circulation channels are formed inside the driven disk; and each second circulation channel extends between at least one axial inner opening formed through a lateral wall of the driven disk, close to the inner edge of the driven disk, and one radial outer opening formed through the outer edge of the driven disk so that the second circulation channel ends only at a given distance from the inner edge of the driven disk. on each driven disk, the second circulation channels are formed inside the driven disk; and each second circulation channel extends between at least one axial inner opening formed through a lateral wall of the driven disk, close to the inner edge of the driven disk, and one radial outer opening formed through the outer edge of the driven disk so that the second circulation channel ends only at a given distance from the inner edge of the driven disk.
