Modern manual transmissions are typically equipped with synchromesh systems for gear change. The requirements to a synchromesh system are well function of the blocking system and comfortable shifting. Thereby friction behavior and wear of the friction clutch are of utmost significance. The tribology of synchromesh systems is affected by a multitude of influencing parameters. These are load - inertia, pressure, sliding speed - lubricant, friction material and the topography of friction surfaces. In practical experience synchromesh systems with sintered friction materials show good friction and wear behavior. By specific test procedures at a test rig, especially p-v-load stage tests and long time endurance tests, in touch with specific evaluation methods, changes in friction and wear behavior of synchromesh systems during endurance life can be detected. In addition new measurement technologies to characterize the topography of the friction surface are used to support experimental studies.
