Abstract
Rotary plate-carrier drum for multi-plate clutches or brakes comprising a bearing plate adapted to encompass a set of keys formed on the outer cylindrical periphery of the drum, the keys being separated by longitudinal slots engaged by the radial extensions of the internal plates and external plates, respectively, of a pair of coaxial clutches. This drum construction is intended more particularly for multi-plate clutches of planetary change-speed transmission mechanisms.
