Advanced transmissions require a smooth shifting system for driving comfort in cars and other road vehicles. AVTEC's ingeniously designed Synchropack offers great performance, comfortable gear shifts and easily integrated into manual and automated manual transmissions.
A synchronizer, or "synchro", is a conduit for smooth shifting from one gear to next, thereby matching the speeds of the gear wheels during the shifting process.
The performance originates from careful design of synchro & friction system, tolerancing, material selection to ensure un-interrupted torque transfer providing high durability and service life.
Synchronizers play crucial role on future development of hybrid and electric vehicles
