Synchronous body for synchronizer of gearbox, has ring parts axially arranged in series and connected among each other by bulge units that are inserted into each other and arranged at distance to each other in circumferential direction

摘要

The body (1) has ring parts (2, 3) axially arranged in series and connected among each other by bulge units (13) that are inserted into each other. The bulge units are arranged at a distance to each other in a circumferential direction. The bulge units are evenly distributed over a periphery and engage in a form-fit manner. The bulge units exhibit a spiral form, and an inner bulge (14) is surrounded by an outer bulge (15). The ring parts are welded with one another and exhibit different wall thickness. The bulges serve as a stopper for a collateral component i.e. synchronous ring.
