ABSTRACT:
A method for manufacturing a frictional locking member, in particular a synchronizing ring. The surface of a metallic base member (2) is provided with a frictional body made of a sintering powder.
In order to simplify the method, the base member (2) is combined with an insert member (20). The insert member has centering means (24) for retaining the base member (2) in a defined position and at a defined distance (23) from the counter surface (22) arranged at a defined distance (23) from the surface (14). The cavity (27) formed by the defined distance (23) between the surface (14) and the counter surface (22) is filled with a sintering powder, and the insert member (20) is sintered together with the base member (2) with the cavity (27) filled (FIG. 4).
