Synchonizers are "blocking" rings that are between the two parts of the transmission that are to be engaged at the time of the shift.
(Between the engagement cogs on any gear and the driven shaft.) The synchonizer ring spins with the driven shaft but is allowed to rotate slightly either direction based on a low amount of friction between it and the spinning gear. When the two parts are spinning at different speeds, the ring "blocks" the engagement of the gear. (It is in the way of the cogs engaging) With pressure on the shifter, the ring is pushed closer to the gear, increasing the friction and speeding-up ( or slowing-down) the gear and input shaft, usually. When the two parts are spinning at the same speed, the ring "floats" to the center position and no longer blocks the engagement of the gear.
