Transmission is difficult
After excluding clutch failure factors, analyze and process as follows:
Can not be hosted, may be lost in the distance, and each linkage is loosened and should be inspected one by one;
Can hang up, but more difficult, it may be the fork axis deformation or rust post, and should be removed from the transmission of the transmission of the fork shaft. If there is a card to repair or replace it; if it is a new transmission, it should Considering whether the cork shaft and the shaft holes are too tight, whether the mutual lock spring is too large, otherwise it should be re-adjusted or processed.
At the same time as the hook of the gear, it is also the sound of the gear, the bonded tooth surface of the joint ring is damaged, the fork bending deformation, the synchronizer cone wear, the guide bearing wear, etc., the transmission should be removed to check the corresponding gear. Synchronizer, engagement teeth, bearing fork, replacement or correction of wear deformation.
Transmission is so good
When the vehicle hangs the reverse gear, the transmission sometimes generates \"哐 哐 \" sound. This is due to the transmission of the transmission inverted gear position, and the round tooth of the pair of gears to be meshed with the end gear is not equal, and the two can not enter the synchronous state mesh, the impact sound is generated. Splendly shift.
Pay attention to two points when operating, avoid meshing impact sound:
Extend the time of step on the clutch before the gear, then select the reverse gear;
When selecting a synchronizer gear, first take the gear to a gear position with the synchronizer, and then do not ring.
Transmission jump gear
The car is in driving, the shift lever is automatically jumped back to the neutral, the engagement sleeve and the sliding gear are disengaged from the meshing position. The running file is in many, the high-speed load suddenly changes or occurs when the car is severely vibrated.
1. When a certain gear is discovered, the shift lever is still pushed into the file, then remove the transmission cover to the gear meshing, such as the gear meshing well, check the shift mechanism;
2. Use the shift fork test positioning device with pushing the jumper. If the positioning is poor, you need to remove the shift of the fork axis, verify the positioning ball and spring, such as the spring too soft or broken, should be replaced. The shifting of the shifting of the tribute should be repaired or replaced;
3. If the gear or gear is not fully engaged, it can be pushed by hand to correct it. It should be checked whether the shift fork is bent or wear is too large, and whether the shift fork fixing screw is loose, the gap between the fork and the gear groove is too large. . Such as the shift of the shift should be corrected; if the wear and the sliding gear groove is excessively loosen, the repair and replacement should be removed;
4. If the shift mechanism is good, the gear is not fully engaged, it should be inspected whether the gear is ground into a cone, and whether the bearing is loosened and replaced if necessary.
Transmission shaft failure and exclude
Drive shaft abnormal sound when car starts or speed changes
1. The car suddenly changed the speed in the driving, and the metal knocking sound, mostly due to individual drive shaft flanges, universal joint shaftsBeing enlarged, you should check or change the universal joint;
2. The vehicle starts or drives the sound, mostly the bearing serious wear or scaffold, must be replaced in time;
3. The vehicle starts or transforms the speed of the vehicle, which is obvious when the low speed is higher than the high speed, and most of the intermediate support bolts are loose.The rack is sounded with the frame. When there is a sound, stop checking, and shake the drive shaft, it can be found in a timely fastening bolt.
