We must have encountered the situation that the mixing bucket loader can't walk. If it can't walk normally, it will certainly affect the normal work. However, don't panic, find out the cause and troubleshoot.
1. Check the oil quantity limit valve and transmission pressure gauge of the transmission. If it is found that there is a lack of transmission variable distance oil, add new oil, but do not add too much, otherwise the transmission will be heated. Usually, add the oil flowing out of the limit valve.
2. Check whether the boom can rise and fall and whether there is steering. If the boom can rise and fall, it can also complete the steering action, but the machine itself cannot realize the process of walking. This is mainly caused by the damage and lack of oil and water of the variable speed pump.
3. If the boom cannot rise and fall, it cannot realize steering action, and it cannot realize walking itself. This situation is mostly caused by the steel plate link of the mixing bucket transmission being cut off by bolts and the elastic plate being broken. Lift out the diesel engine and gearbox together, remove the connection position of the torque converter diesel engine, check the damaged position, and replace and repair the parts.
The mixer truck manufacturer reminds everyone that no matter any equipment fails, they should take it seriously and find the root of the problem, so as to find the corresponding solutions.
Self loading mixer is a kind of engineering machinery, and gear is one of its components. The reason why the gear can rotate is that a pair of good transmission relationship should be formed between the upper gear and the lower gear. Only when the connection between the two is in place, can its operation be a stable relationship. In fact, tooth beating is the hard collision between two metal gears, resulting in faster wear of the crown of the gear. With a long time and more times, the crown of the original right angle will be ground into a fillet. After entering the gear, there will be problems in the bite, and it is easy to fall out of the gear when it vibrates a little. Then, do you know why the mixing bucket has teeth beating?
Normally, there will be synchronizer in the vehicle. Its function is to synchronize the high-speed gear with the gear that is about to enter the current gear. When the differential gear is installed, the number of reverse gears will increase. Therefore, when the differential gear is not installed, the reverse gear will change smoothly. In this way, the reverse gear will occur. In addition to the incorrect quality of spiral bevel gear, meshing pair and adjustment clearance, the incorrect operation process is the primary reason for the toothing problem of the mixing bucket.
