SYNCHRONIZATION SYSTEM FOR GEARBOX WITH FRICTION CONE AND DENTURE ON THE SAME CROWN

摘要

The invention relates to a synchronization system for a gearbox, comprising at least one free pinion (6) carried by a shaft (2) arranged along an axis, and a sliding sleeve (4) driven in rotation by the shaft (2) comprising a first clutch gear (28) with the pinion (6), this sliding sleeve (4) rotating a synchronizing ring (40) comprising a first friction cone (72) rotated radially towards the outside, characterized in that the pinion (6) carries a synchronization ring and clutch (32) formed in a sheet, having an axial flange (34) facing the sleeve (4) ending in a second clutch toothing ( 36), this axial flange (34) comprising a conical inner face receiving the first friction cone (72) of the synchronizing ring (40).
