1701550FAOL sub tank synchronizer assembly

1. (1) The input shaft and output shaft of the transmission rotate at different speeds. When changing gears, the two gears rotate at different speeds. If the gears are forcibly meshed without being "synchronized" first, the impact collision of the two gears will inevitably occur. , thus damaging the gears. (2) The shift of the old transmission should adopt the "two-foot clutch" method. When shifting, first step on the clutch, pull the gear out to neutral, release the clutch, stay in the neutral position for a while, and then step on the clutch again. , put the block into another block. (3) But this operation is more complicated and troublesome. Therefore, modern gearboxes are designed with "synchronizers", through which the gears to be engaged can reach a consistent speed and smoothly engage and shift. 2. The synchronizer has a constant pressure type and an inertia type. At present, all synchronous transmissions use inertial synchronizers, which are characterized by relying on friction to achieve synchronization. 3. There are chamfers (locking angles) on the engaging sleeve, the synchronizing ring and the ring gear of the gear to be engaged. The inner conical surface of the synchronizing ring is in contact with the outer conical surface of the gear ring gear to be engaged to generate friction. The friction of the conical surface makes the gear sleeve and the ring gear to be meshed quickly synchronize, and at the same time, it will produce a locking effect to prevent the gears from meshing before synchronization. 4. When the inner conical surface of the synchronizing ring contacts the outer conical surface of the gear ring gear to be engaged, under the action of the friction torque, the speed of the gear rapidly decreases (or increases) to be equal to the speed of the synchronizing ring, the two rotate synchronously, and the gears are opposite to each other. Since the rotational speed of the synchronizing ring is zero, the moment of inertia also disappears at the same time. At this time, under the push of the force of the shift lever, the engaging sleeve engages with the ring gear of the synchronizing ring without hindrance, and further engages with the ring gear of the gear to be engaged. , and complete the shifting process.

Description

1. (1) The input shaft and output shaft of the transmission rotate at different speeds. When changing gears, the two gears rotate at different speeds. If the gears are forcibly meshed without being "synchronized" first, the impact collision of the two gears will inevitably occur. , thus damaging the gears.

(2) The shift of the old transmission should adopt the "two-foot clutch" method. When shifting, first step on the clutch, pull the gear out to neutral, release the clutch, stay in the neutral position for a while, and then step on the clutch again. , put the block into another block.

(3) But this operation is more complicated and troublesome. Therefore, modern gearboxes are designed with "synchronizers", through which the gears to be engaged can reach a consistent speed and smoothly engage and shift.

2. The synchronizer has a constant pressure type and an inertia type. At present, all synchronous transmissions use inertial synchronizers, which are characterized by relying on friction to achieve synchronization.

3. There are chamfers (locking angles) on the engaging sleeve, the synchronizing ring and the ring gear of the gear to be engaged. The inner conical surface of the synchronizing ring is in contact with the outer conical surface of the gear ring gear to be engaged to generate friction. The friction of the conical surface makes the gear sleeve and the ring gear to be meshed quickly synchronize, and at the same time, it will produce a locking effect to prevent the gears from meshing before synchronization.

4. When the inner conical surface of the synchronizing ring contacts the outer conical surface of the gear ring gear to be engaged, under the action of the friction torque, the speed of the gear rapidly decreases (or increases) to be equal to the speed of the synchronizing ring, the two rotate synchronously, and the gears are opposite to each other. Since the rotational speed of the synchronizing ring is zero, the moment of inertia also disappears at the same time. At this time, under the push of the force of the shift lever, the engaging sleeve engages with the ring gear of the synchronizing ring without hindrance, and further engages with the ring gear of the gear to be engaged. , and complete the shifting process.
