The purpose of the self-lubricating device for the axle of the self-balancing car is to solve the problems that the lubricating oil in the existing self-balancing car can easily lead to the imbalance of the balance function during artificial maintenance, the shell with high integrity is difficult to disassemble, there is no independent lubrication system, and the problems of serious friction and wear. Functionalized graphene polymers are installed at the hub module and the linkage block to ensure good lubrication of the friction parts during long-term operation, and use the collision impact force between the balance car and the ground to make the lubricating matter in the oil tank pass through to prevent leakage The head quantity is delivered to the lower bearing, which ensures the lubrication supply of the balance car, and does not need to buy additional lubricating items, so as to achieve the function of self-lubricating inside the balance car, and the lubricating substances are supplied between the moving parts at any time by themselves, and it also avoids due to lubrication. It has an independent and complete self-lubricating system, which also avoids structural damage caused by maintenance and disassembly, and greatly increases the service life of the self-balancing vehicle.

The invention provides a device and a method for actively promoting landslide collapse. The method comprises the steps that a loosening agent is sprayed to a to-be-slide mass to loosen the soil texture of the mass, hinges provided with self-expansion bag bodies are placed at the positions of slide blocking keys, and extensible double-layer floral tubes are arranged in the horizontal direction of alandslide belt; each bag body is of a double-layer structure, wherein an expanding agent or gas is placed in the inner layer, and the outer layer is filled with lubricating substances; and repeated expansion is conducted, so that a gap is generated between the to-be-landslide mass and a landslide bed, the pressure in the bag bodies is increased, and the lubricating substances enter the landslidebelt. Meanwhile, magnetic fluid mixed with the lubricating substances is arranged at the position of a backup pull fracture belt, the magnetic fluid is guided in a graded mode to be fully distributedon the landslide belt, and the landslide mass is promoted to slide away from the landslide bed through the combined effect. The problems that manpower and material resources are wasted, and normal operation of traffic transportation and construction operation is affected due to long-term monitoring of the to-be-landslide mass are solved. The device and the method have the advantages that feasibility is high, manpower and material resources are saved, and personnel injuries are reduced.

This patent discloses a method for preparing a high-hardness, smooth, and corrosion-resistant surface of ferrous metals. The metal sample to be treated is made into a friction pair. The material of the pair is the same as that of the metal sample to be processed and the hardness is similar. The initial surface roughness of the two pairs is Ra ≤1.6um, and lubricated by lubricating substances, which are lubricating oil, grease and emulsion containing serpentine, attapulgite, kaolinite, montmorillonite and other minerals, using splash lubrication and forced lubrication. The contact form of the friction pair includes surface-to-surface contact and line-to-surface contact. The friction form includes sliding friction and rolling friction. The cumulative friction movement time is not less than 72 hours. This process method is relatively simple, and one process section can realize "improving surface hardness, The comprehensive goal of "smoothness and corrosion resistance" has a certain promotion value.
