Two coaxially arranged elements, e.g. a toothed synchronizing body (2) and a gearwheel (5), rotating at different speeds are coupled together via an axially displaceable annular sleeve 1 which has internal clutch teeth (11) engageable with matching external teeth (21, 53) of the two elements. Spring-loaded pivotable locking members (3) cooperate with projections (41) of synchronizing ring (4) to transmit initial axial movement of sleeve (1) to ring (4), the projections then retaining the locking members in position to baulk further movement of the sleeve until the elements (2, 5) are synchronized - when the sleeve can depress the locking members and complete its travel. Alternate locking members simply engage the back of ring (4) in an alternative embodiment, and a synchronizing plate clutch may be employed instead of the cone clutch shown. <IMAGE> |
