The invention provides a vibration reduction mechanism and a three-piece type bogie applying the vibration reduction mechanism, and relates to the technical field of railway vehicle bogies. The vibration reduction mechanism comprises a base and an elastic vibration reduction assembly arranged on one side of the base, and an abrasion part is arranged on the side, away from the base, of the elastic vibration reduction assembly. The three-piece type bogie comprises a swing bolster, a side frame and the damping mechanism. Based on the technical scheme, the swing bolster and the side frame have a certain rotational degree of freedom in the horizontal plane, and the damping mechanism is reliable in mounting and positioning and convenient to disassemble and assemble, so that the critical speed of the three-piece bogie can be effectively increased, the disassembly and assembly workload of later overhaul and maintenance can be reduced, and the service life of the three-piece bogie is prolonged. And the railway vehicle overhaul and maintenance efficiency is greatly improved.
本发明提供了一种减振机构及应用该减振机构的三大件式转向架,涉及轨道车辆转向架技术领域。其中,一种减振机构,包括底座以及设置于所述底座一侧的弹性减振组件,所述弹性减振组件背离所述底座一侧设置有磨耗件。以及一种三大件式转向架,包括摇枕、侧架及上述减振机构。基于本发明的技术方案,使得摇枕和侧架在水平面内具有一定的旋转自由度,并且减振机构安装定位可靠,拆装方便,从而不仅能有效提高三大件式转向架临界速度,还有助于减少后期检修维护的拆装工作量,大大提高轨道车辆检修维护效率。
