Method for the manufacture of a double-cone synchronizer ring comprising the following steps: manufacture of a first synchronizer ring portion and a second synchronizer ring portion in such a way that the first synchronizer ring portion and the second synchronizer ring portion each comprise a toothed rim (6, 8) on their radially circumferential outer face (3, 4) in proximity to a first end face (5, 7) and each comprise an inner face (9, 12) tapering conically from the first end face (5, 7) towards a second, opposing end face (10, 11), and joining of the first synchronizer ring portion and the second synchronizer ring portion, so that their second end faces (10, 11) lie on top of one other, characterized in that the synchronizer ring portion (1, 2) produced by forming on the second end face (10, 11) comprises at least one connecting portion extending in an axial direction from the second end face (10, 11) and/or at least one recess formed so as to correspond to the connecting portion, and when joining the at least one connecting portion of the first synchronizer ring portion engages in the recess on the second synchronizer ring portion, wherein the connecting portion is a web or a stud extending from the second end face (10, 11) in an axial direction, wherein a connecting rib on a web inner side facing the axis of the synchronizer ring portion (1, 2), and a groove-like depression in the recess corresponding to the connecting rib are each produced by machining, and wherein the first synchronizer ring portion is joined to the second synchronizer ring portion through engagement of the connecting rib in the corresponding groove-like depression. manufacture of a first synchronizer ring portion and a second synchronizer ring portion in such a way that the first synchronizer ring portion and the second synchronizer ring portion each comprise a toothed rim (6, 8) on their radially circumferential outer face (3, 4) in proximity to a first end face (5, 7) and each comprise an inner face (9, 12) tapering conically from the first end face (5, 7) towards a second, opposing end face (10, 11), and joining of the first synchronizer ring portion and the second synchronizer ring portion, so that their second end faces (10, 11) lie on top of one other, characterized in that the synchronizer ring portion (1, 2) produced by forming on the second end face (10, 11) comprises at least one connecting portion extending in an axial direction from the second end face (10, 11) and/or at least one recess formed so as to correspond to the connecting portion, and when joining the at least one connecting portion of the first synchronizer ring portion engages in the recess on the second synchronizer ring portion, wherein the connecting portion is a web or a stud extending from the second end face (10, 11) in an axial direction, wherein a connecting rib on a web inner side facing the axis of the synchronizer ring portion (1, 2), and a groove-like depression in the recess corresponding to the connecting rib are each produced by machining, and wherein the first synchronizer ring portion is joined to the second synchronizer ring portion through engagement of the connecting rib in the corresponding groove-like depression.
