The invention discloses a conical rubber spring with a fireproof function, and relates to the field of structural design of rubber springs for bogies of railway vehicles. The conical rubber spring comprises main conical rubber, a fireproof rubber layer and an isolating layer, the isolating layer is positioned between the main conical rubber and the fireproof rubber layer, and the main conical rubber, the isolating layer and the fireproof rubber layer are made into an integral structure by means of vulcanization. The conical rubber spring with the fireproof function is manufactured on the basisof an existing rubber material, and the flame retardant requirement can be met while the conical rubber spring can bear large mechanical stress. The conical rubber spring has the advantages of beingnot prone to abrasion, high in bonding strength, long in service life and the like, the service life of the conical rubber spring body is prolonged, and manufacturing cost and later-period operation and maintenance cost of a user are saved.
具有防火功能的圆锥橡胶弹簧涉及轨道客车转向架用橡胶弹簧结构设计领域,其包括主体圆锥橡胶、防火橡胶层和隔离层,隔离层位于主体圆锥橡胶和防火橡胶层之间,主体圆锥橡胶、隔离层和防火橡胶层以硫化方式做成一体结构。本发明在现有橡胶材料基础上制作的具有防火功能的圆锥橡胶弹簧,在能够承受大机械应力的同时,又能达到阻燃要求。本发明具有不易磨损、粘接强度高和使用寿命长等优点,增加了圆锥橡胶弹簧主体的寿命,节约了制造成本和用户后期的运营维护成本。
