SELF-SEALING SYNCHRONISER Russian patent published in 2017 - IPC F16D23/02 

FIELD: machine engineering.

SUBSTANCE: in the synchroniser, the pinion gear has a conical synchronising surface made in the pinion gear body from the inside with respect to its teeth coaxially to the pitch cylinder of the teeth. The blocking ring is mounted on the hub of the synchroniser with the possibility of axial movement and rotation relative to the hub by an angle determined by the thickness of the blocking tooth. The movement of the blocking ring relative to the pinion gear in the direction of its movement when the gear is actuated is limited by a spring retainer ring installed in the pinion gear. The synchroniser hub is mounted on the shaft splines and the is pressed against the spring retainer ring mounted on the shaft by the spring. The teeth, by means of which the pinion gear is connected to the shaft, are made on the pinion gear and the hub.

EFFECT: increased synchronisation moment and increased synchroniser resource.
