SYNCHRONIZATION SYSTEM ADAPTED TO SYNCHRONIZE A FIRST ROTATING ELEMENT WITH A SECOND ELEMENT FOR ADJUSTING THE ROTATION SPEED OF THE FIRST ROTATING ELEMENT TO A TARGET REGIME

摘要

A system for synchronizing at a target speed a first rotating element (18) with a second element (36), comprising a rotary synchronizing member (34) and two coaxial coupling devices (40, 42) each having a part, an axially fixed part (40A, 42A), one of which (40A) can rotate integrally with the first element (18) and the other (42A) is connected to the second element (36), and on the other hand a axially movable portion (40B, 42B) integral with the member (34). These movable parts (40B, 42B) are alternately coupled with these fixed parts (40A, 42A) by controlled axial movement of the member (34) to adjust alternately the regime of the fixed parts (40A, 42A) and the organ (34). Application to the synchronization of gearboxes (16) and gearboxes (20).
