Abstract:
1. A synchronizing ring for a synchronization device ( 2 ) of a gear changing transmission, including a conical ring body ( 3 ) with an inner friction surface ( 4 ) and an outer installation surface ( 5 ) bounding the ring body ( 3 ) in a radial circumferential direction (U), extending perpendicular to an axial synchronizing ring axis ( 6 ) and extending conically at a predefinable angle of friction about the axial synchronizing ring axis ( 6 ) of the synchronizing ring, wherein the ring body ( 3 ) is bounded in the axial direction at a largest cone diameter by a gear wheel surface ( 7 ) with a gear wheel ( 71 ) extending substantially perpendicularly to the synchronizing ring axis ( 6 ) and at a smallest cone diameter by a hub surface ( 8 ) and wherein, for the fixing of the synchronizing ring in a cylindrical cavity ( 9 ) of a synchronizing ring hub ( 10 ) in an installed state, means providing security against rotation ( 11 ) is provided, which is integrally connected to the ring body ( 3 ) and extends in a direction away from the gear wheel surface ( 7 ) of the ring body ( 3 ), characterized in that for the guidance of the installation surface ( 5 ) in the cylindrical cavity ( 9 ) a guiding element ( 12 ) is provided at the means providing security against rotation ( 11 ), and wherein the guiding element ( 12 ) extends starting from the means providing security against rotation ( 11 ) in the circumferential direction (U); and wherein the guiding element ( 12 ) extends in the circumferential direction (U) in a region between an outer surface of the means providing security against rotation ( 11 ) and the outer installation surface ( 5 ) with respect to a distance from the axial synchronizing ring axis ( 6 ); wherein the radially outer surface of the means providing security against rotation ( 11 ) has a greater radial distance from the axial synchronizing ring axis ( 6 ) than the guiding element ( 12 ).
