PROCEDIMENTO PER LA REALIZZAZIONE DI UN PISTONCINO DI AZIONAMENTO IN DUE PARTI PER UN FRENO A DISCO |
摘要 |
A process of permanently joining a cylindrical core (2) to a metallic beaker-shaped part (1) which together form an operating piston of a hydraulically operated disc brake includes inserting the core into a bore in the beaker-shaped part, and providing an axially protruding end on the core beyond the annular end surface (7) of the beaker-shaped part having a conical surface (8) extending from its free surface (6) into the front area of the beaker-shaped part (1). A wedge-shaped annular groove (11) is produced in the beaker-shaped part (1), whereby material is radially displaced inwardly so that it abuts against the conical surface (8) of the core to retain the core in the beaker-shaped part. |
