摘要： The invention relates to a friction ring (1) for a synchronization unit of a gear changing transmission. The friction ring (1) comprises a conical friction ring body (4) having an inner friction surface (401) and an outer installation surface (402) which each bound the friction ring body (4) in a radial direction extending perpendicular to an axial friction ring axis (6). The friction ring body (4) is interrupted in a circumferential direction (U) extending around the friction ring axis (6) by a separation point (5) in such a way that a first separation surface (7) and a second separation surface (8) are formed at the separation point (5). In order to ensure that the friction ring (1) takes a controlled axial position relative to a synchronizer ring during the synchronization, the first separation surface (7) and the second separation surface (8) contact each other in a predefinable area in such a way that the friction ring body (4) is shaped in the form of a closed contour in the circumferential direction (U) with a smallest circumference (13).

In accordance with the invention, a guide member (12) is provided for the guidance of the installation surface (5) at an inner surface (91) of the cylindrical hollow space (9) of the synchroniser ring hub (10) at the ring member (3) in a predeterminable region between the gear surface (7) and the hub surface (8). The invention furthermore relates to a manual transmission for a vehicle having a synchroniser ring (1) in accordance with the invention.

摘要： A synchronization unit of a switchable gear changing transmission for a vehicle. The synchronization unit includes a friction ring having an outer installation surface and a synchronizer ring having an inner installation surface. The outer installation surface of the friction ring is shaped as a first geometrically structured profile. The inner installation surface of the synchronizer ring is shaped as a corresponding second geometrically structured profile. The first profile of the friction ring is configured to engage with the second profile of the synchronizer ring in such a manner that the friction ring is secured in the radial direction to the axis and in the circumferential direction at the synchronizer ring.

摘要： Assembly for a synchronization unit of a variable ratio gear transmission. Assembly has a synchronizer ring and a friction ring. The friction ring has a friction surface and an installation surface and the synchronizer ring has a contact surface directed toward the installation surface. To allow a high efficiency of the synchronizing unit and simultaneously a functionally safe and comfortable operation of the variable ratio gear transmission, the synchronizer ring and the friction ring are configured and arranged such that the geometrical shape of the installation surface of the friction ring differs from the geometrical shape of the contact surface of the synchronizer ring in a relief state of a synchronizing process; and that the geometrical shape of the installation surface of the friction ring corresponds to the geometrical shape of the contact surface of the synchronizer ring in a load state of the synchronizing process.
