A spherical rubber pad comprises an upper plate used for being connected with a spring and a lower plate used for being connected with an axle box, a vulcanized rubber layer is arranged between the upper plate and the lower plate, and the connecting face of the upper plate, the connecting face of the lower plate and the rubber layer and the connecting face of the rubber layer are all spherical arc faces. Compared with a flat rubber pad in the prior art, the rubber pad mainly bears vertical loads, the cambered surface design is adopted, the whole rubber is of a hemispherical structure, the deflection rigidity is reduced, and a larger deflection angle can be borne. The vulcanized surfaces of the rubber pad, the upper plate and the lower plate all adopt symmetrical spherical cambered surfaces, so that the rubber pad has equal transverse and longitudinal deflection rigidity, and is suitable for application scenes with relatively consistent transverse and longitudinal deflection angles.

    一种球型橡胶垫,包括用于连接弹簧的上板和用于连接轴箱的下板,在上板和下板之间硫化橡胶层,所述上板、下板和橡胶层的连接面以及橡胶层均为球型弧面。本发明涉及的橡胶垫,相比于现有技术的平板橡胶垫主要承受垂向载荷,采用弧面设计,使橡胶整体呈半球形结构,降低偏转刚度,能够承受更大的偏转角度。橡胶垫、上下板的硫化面均采用对称的球型弧面,使得橡胶垫具有相等的横向、纵向的偏转刚度,适用于横向、纵向的偏转角度相对一致的应用场景。
