What is the reason for the abnormal noise when shifting into reverse gear?
1 Answers
The reason for the abnormal noise when shifting into reverse gear is the friction between gears during gear engagement, and the reverse gear lacks a synchronizer. Friction between gears during gear engagement: When the clutch is depressed, the transmission reverse gear is still rotating for a short period. Engaging the gear at this time will inevitably cause gear grinding. If you wait a few seconds after depressing the clutch until the rotating reverse gear comes to a complete stop before engaging the gear, the abnormal noise will not occur. Reverse gear lacks a synchronizer: For a short time after the clutch is depressed, due to inertia, the internal gears of the transmission are still in a freewheeling state. If the gear is engaged immediately after depressing the clutch, the reverse gear will collide with the speed difference, resulting in resistance and gear grinding noise. Inspect, repair, or replace the damaged synchronizer, and the abnormal noise will be eliminated. Precautions when shifting into reverse gear: Reverse slowly; do not reverse too quickly. Avoid stepping hard on the accelerator for rapid acceleration in reverse, as this can cause significant damage to the straight-cut gears. Additionally, straight-cut gears transmit power very directly, resulting in poor smoothness.
