Multi cone synchronisation system for e.g. utility vehicles, includes concentrically divided inner synchronisation ring cooperating with threaded wheel

摘要

The inner synchronisation ring (4) is divided concentrically into an outer cone ring (4) and an inner cone ring (4), the latter having an inner friction surface (9) for frictional contact with a conical surface (10) on the associated threaded wheel (11). The system (1) comprises an outer synchronisation ring (2) with a conical inner friction surface (3) and a coaxial inner sychronisation ring with a conical outer friction surface (5). At least one double cone ring (6) is provided, having two friction surfaces (7, 8) in frictional contact with the conical inner and outer friction surfaces.
