The invention discloses a side bearing body assembly of a heavy-load railway wagon. The side bearing body assembly comprises an upper side bearing and a lower side bearing. The upper side bearing comprises an upper side bearing seat, an adjusting base plate, a stop and an upper side bearing body which are fixedly connected in sequence from top to bottom, and the upper side bearing also comprises rollers arranged in a groove formed by the upper side bearing body and the stop; three groups of rollers are arranged in parallel; the lower side bearing comprises an upper lining plate, an elastic body and a lower lining plate which are sequentially connected from top to bottom through vulcanization, and two fixing pins are arranged on the bottom surface of the lower lining plate; and the rollingsurface of each roller of the upper side bearing is in rolling contact with the surface of the upper lining plate of the lower side bearing. Overall structural strength of a bogie frame is brought into full play, four-point side bearing loading is adopted, loads are evenly distributed, unbalance loading is avoided, and design difficulty of the structural strength of the frame is greatly reduced; and a constant contact rolling friction structure is arranged between the upper side bearing and the lower side bearing, a proper rotation resistance torque can be provided, linear operation stabilityand a curve passing capacity of a vehicle are guaranteed, and vertical loads of a vehicle body and large-tonnage goods are borne and transmitted together.
本发明公开了一种大载重铁路货车旁承体总成。包括上旁承和下旁承,上旁承包括由上至下依次固定连接的上旁承座、调整垫板、止档和上旁承体,和设置于上旁承体与止档构成的凹槽中的滚子;滚子平行设置三组;下旁承包括由上至下通过硫化依次连接的上衬板、弹性体和下衬板,下衬板底面设置两个固定销;上旁承的各滚子滚动表面与下旁承的上衬板表面滚动接触。本发明充分发挥转向架构架整体结构强度,采用四点旁承承载,载荷均匀分配,不产生偏载,构架结构强度的设计难度大大降低;上、下旁承之间为常接触滚动摩擦结构,可提供适宜的回转阻力矩,保证了车辆的直线运行稳定性及曲线通过能力,共同承载并传递车体及大吨位货物的垂向载荷。
