Transmission | Synchronizers Construction

Synchronizers are used to reduce gear wear and reduce the noise level during operation resulting from the impact of the teeth when shifting gears. The synchronizer includes three elements: leveling angular velocities (conical rings); blocking inclusion (blocking fingers); including gears (gear clutch). The truck gearbox synchronizer is a mobile clutch with a disk, which is affected by the shift fork, and with gear teeth. The coupling is mounted on the splines of the driven shaft. The clutch disc has three holes for the locking fingers connecting it to two interlocked conical rings, and for the locking fingers that rigidly connect the conical rings. There are springs in the locking fingers. In the neutral position, the synchronizer housing is located in … Continue reading Transmission | Synchronizers Construction
