Synchronizing unit for gear systems, e.g. motor vehicle gear systems, comprises at least one friction contact surface, located between the thrust elements and the synchroring which consists of a low-friction material

摘要

The synchronizing unit for gear systems comprises at least one friction contact surface (56, 58) located between the thrust elements (54) and the synchroring (34, 36) which consists of a low-friction material. As a result, relative motions are resisted using only small friction torques. An Independent claim is also included for a thrust element at least partially coated with a low-friction material.
