About synchronizers

Synchronizers are one of the key performance-defining components of modern MT, AMT and DCT transmissions. Synchronizers are responsible for smooth and comfortable gear shifting in automobiles and other road vehicles. Since the different gears normally run at different speeds, a smooth shift from one gear to another requires a synchronizer to match the speeds during the actual shift. The performance of the synchronizer system is defined by the design of the friction system and the form-fit torque transfer. The synchronizer system has a significant influence on the overall mechanical efficiency of the transmission, and hence the fuel efficiency of the vehicle. Synchronizers are also crucial to the future development of hybrid electric vehicles.
