A wheel-rail low-power bogie comprises side frames, a spring supporting plate, a spring bearing seat, a spherical wear-resistant gasket and spherical positioning seats; and the two spherical positioning seats are respectively arranged on the mounting surfaces of inner cavities of lower chords of central square frames of the two parallel side frames, and are transversely and symmetrically arrangedalong the side frames, and the centers of spheres of the spherical positioning seats are positioned in the longitudinal directions of the side frames, namely the central plane along the running direction of the vehicle. Transverse swing of the rail wagon side frames is effectively controlled through the two spherical positioning seats, the positioning reliability is high, and the problem of positioning reliability of a swing device in the prior art can be solved.
一种轮轨低动力作用转向架,包括侧架、弹簧托板、弹簧承载座、球面耐磨衬垫、球面定位座;球面定位座为两个,分别设置于两个平行布置侧架的中央方框的,下弦杆内腔的安装面上,沿侧架横向对称布置,其球心位于侧架的纵向,即沿车辆运行方向的中心平面内。本发明通过两个球面定位座有效控制铁路货车侧架横向摆动,定位可靠性较高,可以解决现有技术存在的摆动装置定位可靠性问题。
