Abstract:
1. 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 first disks housed inside the housing and angularly integral with one of the housing or the hub, wherein at least one lateral wall of each first disk has a covering of friction material; a number of second disks housed inside the housing, alternating with the first disks, and angularly integral with the other one of the hub or the housing; at least one oil inlet into the housing; and at least one oil outlet from the housing; wherein each first disk comprises a number of rectilinear first circulation channels, that are formed in the covering of friction material covering the lateral wall of the first disk, are equally spaced about the longitudinal axis of rotation, extend radially from an inner edge of the first disk to an outer edge of the first disk, and are completely separated and isolated one from the other; and wherein each second disk comprises a number of rectilinear second circulation channels, that are equally spaced about the longitudinal axis of rotation, are formed in the second disk, and extend radially from axial inner openings formed through a lateral wall of the second disk, close to an inner edge of the second disk, to radial outer openings formed through an outer edge of the second disk so that each second circulation channel ends at a given distance from the inner edge of the second disk.
