•  A triple synchronizer mechanism using more rings than the double synchronizer mechanism is used 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.
