Bulldozer fault: the solution of the main clutch slipping
Bulldozer is a kind of engineering vehicle. The front is equipped with a large metal earth knife. When it is used, the earth knife is pushed down, and the mud, sand and stone are pushed forward and pushed. The position and angle of the earth knife can be adjusted. Bulldozer can complete excavation, soil handling and soil unloading work independently, and has the characteristics of flexible operation, convenient rotation, small working surface and fast running speed. It is mainly suitable for shallow excavation of one or three types of soil, such as site cleaning or leveling, small excavation depth of foundation pit, as well as backfill, high embankment and so on.
In the actual use of the project, bulldozers will also have some failures, the following Xiaobian to talk about the main clutch slip troubleshooting, take a look at it!
When the main clutch of the bulldozer is slipping, the engine speed is normal and the smoke is not black. The working device works normally, but the machine climbs uphill and can not even walk. The main clutch sliding is the most common failure of bulldozers, the main reasons are: the main and driven plate wear; adjustment plate lock pin welding; the main clutch control rod is not in place; the adjustment disk and flywheel cover thread occlusion is poor. Clutch slippage is sometimes very difficult to handle, and the general repairman's method is to rotate the disc repeatedly. If multiple adjustment after the clutch is still slipping, is often the first to remove transmission and blindly remove the main clutch, so not only to find the fault point and easy to damage other parts, production delays, the result will cause major economic losses. To this end, the investigation should be based on the above possible reasons for careful analysis in order to bear fruit.
For example: a TY220 bulldozer working in the Yellow River, sometimes the main clutch slipping phenomenon, the initial adjustment by the adjustment of the machine can barely work, but before long pin screw trip, so that only the main clutch will remove two screw pin all the new ones, and check all the parts (parts no damage, and the main driven plate basically no wear machine) returned to normal. But after a month, the main clutch appeared skid phenomenon, and finally reached every 2h to adjust a clutch, so that the construction can not be carried out. At that time, had decided to replace the full set of the main clutch, but this is not only a waste of money, but also because the production of busy time is not allowed, after several adjustments, just push a few bulldozer shovel or spade began to appear after dozens of clutch slipping phenomenon, is finally decided to adjust disc and fly wheel cover end screw occlusal variation test by. Therefore, after adjusting the main clutch, the locking pin rod is locked by locknut.
After the treatment of this method, the machine has been used for half a year without adjusting the main clutch, indicating that the fault point is right.
