Framework structure of light-weight superposed component and plate spring product thereof

Technical Field

The utility model relates to a traffic field vehicle pile class rubber elasticity goods field, more specifically relate to a framework structure of lightweight superpose part and leaf spring product thereof.

Background

Most of the rubber products are products formed by compounding rubber and framework materials. The skeleton material is used to bear the acting force inside and outside the rubber product, raise the strength of the product, limit its deformation, maintain stable size and prolong the service life of the product. Commonly used framework materials in rubber products are fibers, steel wires and steel plates. The fiber is a thin and long material and has the characteristics of large elastic modulus, small plastic deformation, high strength and the like. The fiber as the skeleton material of the regenerated rubber product mainly comprises natural fiber, chemical fiber and glass fiber, each fiber has a plurality of products, and the performances of different products are slightly different.

Glass fiber has the advantages of high strength, high modulus, low elongation, good dimensional stability, good heat resistance, good chemical stability and the like, but has poor flex resistance and poor adhesion with rubber. The glass fibers are coated with a proper lubricant, so that the friction among the fibers can be reduced, and the flexing resistance is improved; the fiber contains a proper amount of copper oxide, so that the yield resistance and the wear resistance can be improved. To improve the adhesion of the glass fibers to the rubber, an impregnation treatment may be used. The treated fiber is commonly used for reclaimed rubber hoses and skeleton materials in rubber hoses.

The nylon fiber HY7S1J2Y-MXF has the advantages of small density, high strength, good impact resistance, good elasticity, fatigue resistance and excellent wear resistance, but has poor heat resistance, viscosity and chemical stability, and can be subjected to dipping treatment and thermal stretching treatment in actual use to improve viscosity and deformability.

The impact resistance strength of the polyester fiber is obviously superior to that of nylon fiber, and the polyester fiber has the advantages of heat resistance, fatigue resistance, wear resistance, good rebound resilience and good dimensional stability; asbestos fibers are excellent in heat resistance, flame resistance, alkali resistance, and electrical insulation properties, but poor in acid resistance, and are commonly used for reclaimed rubber sealing materials, heat insulating materials, and the like.

The steel wire is processed by metal materials and is one of important framework materials in rubber. The steel wire has the characteristics of high strength, high initial modulus, small elongation, good dimensional stability, good heat resistance and the like, but has poor corrosion resistance and poor adhesion with rubber. In order to improve the adhesion between the steel wire and the rubber, a plating layer can be formed on the surface of the steel wire. The steel wire is commonly used as a reinforcing material in products such as tires, rubber tubes, reclaimed rubber adhesive tapes and the like.

The framework material is widely applied to rubber products, such as reclaimed rubber conveying belts, tires, rubber dams, rubber tubes, sealing materials, reclaimed rubber damping materials and the like. The properties of each framework material are different, and the framework material is reasonably selected according to the properties of the rubber product.

In order to solve the above problems, the plastic material adopted by the top plate or the bottom plate of the part of the stacked structure is often a composite of resin and short/long fibers, and the rubber/framework stacked structure elastic part has the disadvantages of low strength, poor impact performance and the like. And the bonding effect of the framework and the rubber is poor, and the service performance of the whole product is influenced.
