ABSTRACT:
The invention concerns a friction disc for a clutch, of the kind comprising a central hub having a plurality of radial blades carrying the friction linings on each outer face. The friction disc is provided with axial resiliency or "give" by forming each radial blade from two axially displaceable plates which are urged apart elastically, and coupling means are provided between the plates to limit the degree of axial displacement thereof. According to the invention, the coupling means comprise a lug integral with one plate which engages in a simple recess formed in the lateral edge of the other plate. Preferably a lug and a recess are formed in each plate, and the plates are identical.
The construction simplifies the assembly of the friction disc and provides significant cost savings in manufacture.
