Original Fast Transmission/Gearbox Parts Secondary Box Synchronizer Assembly
Working principle of the Fast gearbox synchronizer assembly:
♦ Shift preparation stage: When the driver operates the shift lever to prepare for shifting, the shift fork will push the spline hub and the synchronizer ring to move in the direction of the gear to be meshed. At this time, there is a speed difference between the synchronizer ring and the gear to be meshed, and the inner cone surface of the synchronizer ring and the outer cone surface of the gear to be meshed have not yet fully contacted.
♦ Synchronization process: As the spline hub and the synchronizer ring continue to move, the inner cone surface of the synchronizer ring begins to contact the outer cone surface of the gear to be meshed. Due to the speed difference between the two, friction will be generated. Under the action of friction, the speed of the gear to be meshed gradually increases or decreases, gradually approaches the speed of the current gear, and synchronization is achieved.
♦ Shift completion stage: When the speed of the gear to be meshed is completely synchronized with the speed of the current gear, the slider, under the action of the spring, makes the synchronizer ring fully mesh with the gear to be meshed. At this time, the spline hub and the gear to be meshed are connected together through the synchronizer ring, and the power can be smoothly transmitted from the current gear to the gear to be meshed, completing the shift operation.

Advantages of Fast Gearbox Synchronizer Assembly:
• Improve gear shifting smoothness: It can effectively eliminate the impact and noise between gears during gear shifting, making the gear shifting process smoother and more comfortable, and reducing the wear on the gearbox and other vehicle parts.
• Shortening gear shifting time: It can quickly make the gears to be meshed reach the synchronous speed, shorten the time interval of gear shifting, and improve the acceleration performance and driving efficiency of the vehicle.
• Easy to operate: Compared with gearboxes without synchronizers, Fast Gearbox Synchronizer Assembly can reduce the driver's operating force when shifting gears, making the gear shifting operation easier and more convenient.
Application range of Fast Gear Gearbox Synchronizer Assembly:
It is widely used in the gearboxes of various heavy-duty trucks, medium-duty trucks, engineering vehicles and other commercial vehicles produced by Fast, and is an important component to ensure the normal driving and good performance of the vehicle.
