It is one of the important transmission components of the gearbox loader, and the overrunning clutch is the key component of the normal transmission of the gearbox. Therefore, if the overrunning clutch fails in use, we can judge it quickly, and the time to disassemble and repair the machine will be reduced. The following are some tips for quickly judging whether the overrunning clutch of loader gearbox is faulty.
?? 1. When the loader starts to shift gears, the response of the machine is slow, and there are no abnormalities in the shift lever and speed change pressure device, which may be caused by improper meshing of the internal and external gears of the overrunning clutch.
? 2. During normal driving, the gearbox suddenly makes strange noise, and then the speed of the loader decreases sharply. After the accelerator is released, there is no need to pick up the gear, the transmission noise disappears and the loader becomes normal. If this phenomenon often occurs, the roller of the overrunning clutch is card issuing and needs to be repaired.
?? 3. When the speed of the loader in the first and second gears remains unchanged, the roller of the overrunning clutch may be stuck at a certain position, resulting in the constant engagement of the internal and external gears.
?? 4. The loader operates normally in gear, but the power is suddenly cut off. During shutdown inspection, it is found that the oil level, filter screen and variable speed pressure are normal. At this time, the overrunning clutch may be faulty.
