•  A triple synchronizer mechanism using more rings than the double synchronizer mechanism has been adapted for the first, second and third gears to improve synchromesh capacity by increasing the friction surface area.

•  The triple synchronizer mechanism consists of a synchronizer ring, middle ring, and inner ring.

•  The gear side inner surface of the inner ring can also be used as a friction surface in the triple synchronizer mechanism. This provides a stronger synchronization force compared to the double cone synchronizer mechanism and reduces operation force and meshing time.
