FREE-COUPLING CLUTCH Russian patent published in 2010 - IPC F16D41/67 F16D41/06 F02N15/02 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in the capacity of starter freewheeling clutch. Freewheeling clutch contains concentric located driving and driven iron rings, installed between them separator with projections and windows for connecting cylindrical roller. On reciprocal surfaces of iron rings there are implemented socket for connecting cylindrical rollers. On inner surface of driving iron ring there are implemented grooving with projections, into which there are located projectors of separator with limited capacity of angular displacement. At movement of connecting cylindrical rollers in windows of separator into clutch shutdown position of separator it is happened its circumferential shift, enlarging spanning angle and area of passing surfaces of separator, and also spanning angle and areas of compression radius surfaces of segmented sockets of driving iron ring. In space between radial surfaces of projections of driving iron ring and projections of separator there are located rectangular volute springs. Segmented sockets of driving iron ring are implemented asymmetric relative to its projections, which are closed by side surfaces of separator projections.

EFFECT: reliability and durability growth and clutch operation, and also design simplification.
