Synchromechanismus für Getriebe

摘要

In a synchroniser for a transmission, a synchroniser ring (34,35) with baulking teeth (34b,35b), is prevented from chattering by an inertial mass (e.g. a ball) (25) mounted in the clutch hub (21) (e.g. in a recess (24)) to be movable radially under the action of centrifugal force, to act against a slope (38) formed on an projection (37) on the synchroniser ring (34,35) to urge the ring (34,35) axially (e.g. against the bias of a wave spring (36)) away from the rotary member (27,28) connectable to the hub (21) by splines (26a,32b,33b) when a hub sleeve (26) is moved towards the member (27,28). $$
