UNIT ELASTIC ASSEMBLY WITH GLOBALLY ANNULAR PARTS AND CLUTCH MECHANISM COMPRISING SUCH A UNIT ELASTIC ASSEMBLY

摘要

Unit elastic assembly (10) of the type comprising at least one generally annular part of the diaphragm type (A10), that is to say a generally annular part comprising a circularly continuous peripheral part (33), forming a Belleville washer, and a central part ( 34) fragmented into radial fingers by slots: said assembly (10) comprises a second generally annular part (B10) consisting of at least one annular washer (35) called assistance, said annular assistance washer (35) being in line with the circularly continuous peripheral part (33) of said diaphragm (A10) with which it is assembled, said annular assistance washer (35) also exerting an axial force in the opposite direction to that of the diaphragm (A10) during a at least part of the expansion stroke of the unitary elastic assembly (10).
