ABSTRACT:
The fastening of a diaphragm spring to the casing of a clutch is effected by means of a annular piece that acts elastically on the diaphragm independently of the riveting, offering a high degree of resistance to flexion between rivets, which piece is of a hollow and incomplete toroidal shape in a support zone on the diaphragm, which zone presents an angular extension of more than 180.degree., permitting an elastic deformation or a reduction of its height of assembly without exceeding the elastic limit of the material that originates the elastic force necessary for the perfect operation of the device and at the same time absorbing the dimensional differences due to the necessary and admissible tolerances of manufacture, with the special feature that the interior part of the said piece is provided with a flange for increasing the moment of inertia of the section of the piece, increasing resistance to flexion between two consecutive orifices of the said piece.
