The invention relates to a synchroniser ring (1) for a synchronisation device (2) of a shiftable change speed gear transmission including a conical ring member (3) having an inner friction surface (4) and an outer installation surface (5) which each bound the ring member (3) in a radial peripheral direction and extend conically around an axial synchroniser ring axis (6) of the synchroniser ring at a predeterminable friction angle (α). The ring member (3) is bounded in the axial direction at a largest conical diameter (d1) by a gear surface (7) with a gear (71) extending substantially perpendicular to the synchroniser ring axis (6) and is bounded at a smallest conical diameter (d2) by a hub surface (8). To fix the synchroniser ring in a cylindrical hollow space (9) of a synchroniser ring hub (10), a security against rotation (11) is provided which is integrally connected to the ring member (3) and extends from the gear surface (7) of the ring body (3) in the direction toward the hub surface (8). In accordance with the invention, a guide member (12) is provided for the guidance of the installation surface (5) at an inner surface (91) of the cylindrical hollow space (9) of the synchroniser ring hub (10) at the ring member (3) in a predeterminable region between the gear surface (7) and the hub surface (8). The invention furthermore relates to a manual transmission for a vehicle having a synchroniser ring (1) in accordance with the invention. |
