FIELD: machine building.
SUBSTANCE: invention relates to devices for the transmission/drive train. The switching device with the synchronizer comprises a shaft, a hub, a clutch, a gear, a synchronizer ring and lever elements. The hub recesses comprise the upper part of the latter being inserted into the groove of the switching clutch. The inclined clutch surfaces contact with the upper parts to enable transmission of axial pressing force to the surfaces of the ring appreciating the pressing force effect. The frictional moment affect arm elements with the first ring protrusions. The arm elements have first sliding surfaces made with possibility to contact with the first guiding surfaces of the hub, and the second sliding surfaces made with possibility to contact with the second guiding surfaces of the hub.
EFFECT: invention simplifies the transmission/drive train design.
