The invention discloses a railway vehicle and a bogie thereof, the bogie of the railway vehicle comprises a framework, a side beam connecting device, a traction device, a driving device, a braking device, a primary suspension and a secondary suspension device, the framework is composed of two side beams, and the two side beams of the bogie are transversely distributed along the railway vehicle; the side beam connecting devices are two axle bridges which are longitudinally distributed along the rails; the two side beams and the two axle bridges are connected through a primary suspension to form a #-shaped structure; one end of the traction device is connected to a shaft body in the middle of the axle, and the other end is connected to a traction seat connected with the vehicle body chassis; the driving device is mounted on the outer side of the side beam; and the secondary suspension is mounted in the sunken area of the side beam. According to the bogie of the railway vehicle, a traditional bogie structure is broken through, the bogie without a cross beam and an end beam is formed, the structure is simplified, the weight is reduced, and the manufacturing cost is reduced.

    本发明公开了一种轨道车辆及其转向架,其中轨道车辆的转向架包括构架、侧梁连接装置、牵引装置、驱动装置、制动装置、一系悬挂、二系悬挂装置,构架由两个侧梁构成,转向架的两个侧梁沿轨道车辆横向分布;侧梁连接装置为两个轴桥,沿轨道纵向分布;两个侧梁和两个轴桥之间通过一系悬挂连接,形成“井”字形结构;牵引装置的一端联接在轴桥中部的轴身上,另外一端连接在与车体底架联接的牵引座上;驱动装置安装在侧梁的外侧;二系悬挂安装在侧梁的凹陷区域。本申请提供的轨道车辆的转向架突破了传统转向架结构,形成无横梁、无端梁型转向架,结构简化、重量减少、制造成本降低。
