| 摘要 |
<p>The invention relates to a synchronizing ring (1) for synchronized manual transmissions, which is produced by shaping a flat metal material. The conical friction surface (6) is provided with grooves (8) which are produced exclusively by axially displacing a tool in relation to the friction surface (6). Said friction surface (6) remains uncoated. In the region of the friction surface (6), the counter conical ring, as well as the friction surface, does not have a subsequently applied friction layer.</p> |
