摘要： Assembly for synchronization unit of gear-changing transmission includes a friction ring and synchronizer ring. Friction ring has a conical friction ring body with friction surface and an installation surface that respectively bound friction ring body in a radial peripheral direction extending perpendicular to an axial friction ring axis. Friction surface extends at a predefinable friction angle and installation surface extends at a predefinable installation angle, in each case conically. Synchronizer ring has a contact surface corresponding to installation surface of friction ring. Synchronizer ring and friction ring are adapted so that contact surface of synchronizer ring contacts installation surface of friction ring, and friction surface of friction ring is in rubbing contact with a gear wheel during a synchronization process where synchronizer ring is displaced in a direction of a gear wheel to be synchronized. Installation surface of friction ring and/or contact surface of synchronizer ring has/have adhesion-reducing surface structure.

摘要： A heat treatment method is capable of molding, by mobile quenching of induction quenching, an outer joint member of a tripod type constant velocity universal joint having excellent strength without forming hardened layers in larger radially-inner portions. Mobile quenching is performed in such a manner that a high-frequency induction heating coil is moved in an axial direction relative to an outer joint member, and thus hardened layers are formed on the roller guide surfaces. Magnetic field line cut-out bodies for cutting out generated magnetic field lines are arranged on the high-frequency induction heating coil. The larger radially-inner portions become an unquenched portion by cutting out the magnetic field lines with the magnetic field line cut-out bodies.
