FRICTION CLUTCH Russian patent published in 2004 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to friction clutches with wear compensators and it is designed for use in drives of heavy trucks. Proposed friction clutch contains pressure disk installed with no possibility of rotation relative to cover plate but with possibility of limited axial shifting. At least on plate spring is installed between cover plate and pressure disk to load pressure disk in axial direction relative to cover plate, and adjusting device to provide at least approximately constant tension of plate spring during entire service life of friction clutch used in drive. Novelty is that friction clutch contains spring releases which provide axial displacement of pressure disk relative to cover plate when friction clutch is disengaged with disengagement of pressure disk and progressive distribution of load at least at this way of disengagement. EFFECT: simplified design, optimization of functional parameters, stabilization of load distribution at release of clutch, prevention of intolerable overload. 31 cl, 16 dwg
