The synchronizer ring also called blocking ring, balk ring or friction ring, has a conical surface which comes into contact with the friction cone of the gear wheel.
The purpose of the synchronizer ring is to produce friction torque in order to decelerate/accelerate the input shaft during a gearshift.
A synchronizer adjusts the speed of the shaft so that the gears align more quickly as you shift.
The slider pushes against the keys or balls in the synchronizer, which then push against the blocker ring.
That ring then pushes against the gear's cone, and the friction it causes helps the shaft speeds to equalize.
