Advancements in engine technology have increased overall torque rating of engine and demanded further improvement in transmissions to sustain higher input torque. Conventional brass synchronizers have proved inadequate for these torque and gear inertia. It becomes necessary to use advanced material science and enhanced technology to synchronizer capabilities.

Multi-cone compact synchronizer with carbon composite friction material technology has been tested successfully for these more demanding applications. This paper will focus on some of the key challenges in modern synchronized transmission, and way forward to address those. Some of the key areas delivering highest impact are being discussed.

A combination of various techniques has enabled a significant reduction in overall transmission length along with enhancement in shift effort, life and overall performance.
