A clutch mechanism is configured to be driven in rotation about an axis and includes two assemblies. Each assembly includes: an outer disk carrier externally delimiting a cavity; a clutch including a stack of coupling disks and friction disks, the stack being housed in the cavity and configured to be driven in rotation about the axis; and a reaction member of the outer disk carrier configured to enable compression of the coupling disks against the friction disks in a clutch engaged position of the corresponding clutch. The clutch mechanism includes at least one device for assembling the two assemblies to one another.

The method according to the invention involves a hot-forging step and a cold-forging step that occurs after the hot-forging step. A polar wheel () incorporating a plurality of finite chamfers () formed on exterior parts of the polar teeth () is produced during the hot-forging step. According to the invention, the cold-forging step involves substeps of placing the polar wheel in a die, cold die-stamping the polar wheel with a first and a second blow in the axial direction of the polar wheel, upsetting material onto interior parts of the polar teeth () so as to form magnet-housing grooves () and magnet lips ().
