Abstract
The utility model relates to an ethylene-propylene-diene monomer rubber anti-vibration pad for a railway vehicle, which is mainly used under floors of a coach of a subway, light-rail and high-speed railway train to realize an anti-vibration function and comprises an anti-vibration pad body (1). The ethylene-propylene-diene monomer rubber anti-vibration pad is characterized in that the cross section of the anti-vibration pad body (1) is a hollow square structure, a kidney-shaped circular through hole (2) is disposed in the center of the anti-vibration pad body (1), and the anti-vibration pad body (1) is mainly made of ethylene-propylene-diene monomer rubber 4551A. The ethylene-propylene-diene monomer rubber anti-vibration pad is mainly made of the ethylene-propylene-diene monomer rubber, the molecular mass is increased while narrow molecular mass distribution is maintained, accordingly fine deformation resistance and collapse resistance are maintained, and the excellent vulcanized shape of a product is kept. Anti-vibration performance of the ethylene-propylene-diene monomer rubber anti-vibration pad can be optimized, and requirements of design parameters (static rigidity and dynamic-to-static ratio) are met.
Description
Technical field
The utility model relates to a kind of rubber damper.Be mainly used in subway, the following damping effect of light rail and high-speed railway railway car floor.Help to improve the quiet comfort level of environment inside car.Belong to the rubber product technical field.
Background technique
As everyone knows, natural rubber has damping property par excellence, but damping parameter designing requirement according to subway, light rail and high-speed railway railway car floor damping pad, the material hardness of vibration damping need be below 50 Shore A, and can extrude smoothly, ganoid natural rubber sizing material can't fine assurance product cross section shape under this hardness, product sulfuration back distortion is subsided serious.Simultaneously, damping pad is solid construction at present, and damping property is poor, can not satisfy design parameter (the quiet rigidity and the output ratio of Q-switching to free running).
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can keep the good good used for rail vehicle ethylene propylene diene rubber damping pad of subsiding property of resistance to deformation, damping property.
The purpose of this utility model is achieved in that a kind of used for rail vehicle ethylene propylene diene rubber damping pad, comprise the damping pad body, described damping pad body cross-section is the hollow square structure, this damping pad body center is provided with an oval shape through hole, and this damping pad body material of main part adopts ethylene propylene diene rubber.
The beneficial effects of the utility model are:
It is material of main part that the utility model is selected ethylene propylene diene rubber for use, can keep narrow molecular weight distribution when improving molecular weight, thereby keeps good subsiding property of resistance to deformation, and product sulfuration shape keeps good.The utility model can be optimized damping property, satisfies design parameter (the quiet rigidity and the output ratio of Q-switching to free running see Table 1).
