Oerlikon Graziano has developed a family of synchronizers for heavy-duty truck transmissions that improves fuel efficiency and ease of shifting. The synchronizers save fuel by optimizing the shift to minimize torque interruption and by reducing steady-state drag torque in the transmission. Other features include durability, long life, an internal activation system, and lubricant paths for improved efficiency. Synchronizers are configured in single and double cone arrangements with torque capacity up to 18,000 N·m (13,275 lb·ft) and use molybdenum coated steel cones for durability with optimum friction. By increasing the speed of a manual shift, synchronizers reduce the torque interruption, extending engine efficiency and reducing transients to save fuel. The first applications of the technology include 9- and 14-speed premium gearboxes.
