In our work environment in the car has become an essential part of our products, the automobile leaf spring is a necessary accessory of the car, here is what we have to play the role of lubrication of steel plate spring, which not only choose the problem will not, can guarantee the service life of steel plate spring.
Spring form stretching under impact load, steel sheet and steel sheet to produce strong friction, or extruding phenomenon, two friction surfaces and produce two different directions of the friction plate spring leads to temperature increase, the surface strain, showing a strong fine lines, in the impact of the load frequency at the same time increases, the friction force generated by stretching movement has also increased, will lead to the fatigue limit or monolithic whole stack fracture at the point of stress concentration. According to the mechanical movement principle test proves that a steel pressure do stretching motion, increasing steel temperature in motion when the frequency increases strength decreased, appeared strong sheath in the stress concentration point and gradually expanding and deepening to the fatigue limit can be damaged. The same is true of the steel plate spring, but it has a higher elasticity than the general steel durability. In addition to other reasons, the main reason for the fracture of the steel plate is the bad lubrication, which should be paid attention to by the driver and the technical management personnel. We do not know what problems we will be using when we know what spring lubrication is.
