The invention relates to the technical field of bogies, and discloses a plate spring suspension three-axle bogie and a railway vehicle. Only one plate spring suspension system is arranged on each side of a wheel set assembly, the two ends of each plate spring suspension system are connected with plate spring connecting seats on a framework assembly, and the middle of the bottom of each plate spring suspension system is connected with the top end of each axle box; the framework assembly is of a frame structure defined by the two side beams and the two end beams, so that the three-axle bogie is simple in structure on the basis that the bearing capacity is guaranteed, and the assembling steps of the three-axle bogie are simplified; in addition, the three-axle bogie is provided with double-side tread brake shoes for braking, so that the stress on the two sides of a wheel pair is equal during braking, the heat dissipation of the brake shoes is faster, the abrasion loss is small, the number of the brake shoes acting on each wheel is doubled, and the stress area of the brake shoes is doubled; when a railway vehicle is loaded with heavy goods, on the premise that the total brake shoe pressure is not changed, the pressure borne by the brake shoe in unit area is small, and therefore the service life of wheels and the service life of the brake shoe are prolonged.
本发明涉及转向架技术领域,公开了一种板簧悬挂三轴转向架及轨道车辆,在轮组组成的每一侧只设置一组板簧悬挂系统,板簧悬挂系统两端与构架组成上的板簧连接座连接,底部中间连接每组轴箱顶端,并且构架组成为两侧梁和两端梁围成的框架结构,使得三轴转向架在保证承载能力的基础上,结构简单、简化了三轴转向架的组装步骤;另外本发明的三轴转向架设置双侧踏面闸瓦制动,使得制动时轮对的两侧受力均等,闸瓦散热较快,磨耗量小,且作用于每个车轮的闸瓦数目增加一倍,闸瓦受力面积增大一倍;当轨道车辆装载重载货物时,在总制动闸瓦压力不变的前提下,闸瓦单位面积上承受的压力较小,从而延长车轮及闸瓦的使用寿命。
