The Science of Synchronization

The next step in the design was synchronization. To synchronize means to coordinate several events to take place at the same time. Soldiers synchronize their watches before a mission to make sure everyone is on the same time schedule. Synchronized transmissions are easy to use, eliminating the driver’s having to match shaft speeds for each shift and creating a smooth, clash-free gear engagement with only a clutch release necessary. Synchronizers are one of the most-misunderstood parts of the transmission, and as with zippers everyone knows how to use one but most people have little or no clue as to how they work.
