The invention discloses a radial bogie and a rail vehicle, and relates to the technical field of rail transit. The radial bogie comprises a rack and an axle rotationally arranged on the rack, and further comprises a first wheel pair assembly and a second wheel pair assembly. Wherein the first wheel set assembly is used for being matched with an axle located at the head of the rack and comprises a first axle suspension box and a first pull rod, one end of the first pull rod is connected with the rack, the other end of the first pull rod is connected with the first axle suspension box, and the first pull rod is arranged in the length direction of the rack and located at the center line position of the rack; the second wheel set assembly is used for being matched with an axle located at the tail of the rack and comprises a second axle suspension box and a second pull rod, one end of the second pull rod is connected with the rack, the other end of the second pull rod is connected with the second axle suspension box, and the second pull rod is arranged in the length direction of the rack and located at the center line position of the rack. The first pull rod and the second pull rod which are used for transmitting force in the bogie transmit force in the longitudinal direction, are not prone to breakage and are high in reliability.
本发明公开了一种径向式转向架及轨道车辆,涉及轨道交通技术领域。径向式转向架包括机架和转动设于机架的车轴,还包括第一轮对组件和第二轮对组件。其中,第一轮对组件用于与位于机架头部的车轴配合,包括第一抱轴箱、第一拉杆,第一拉杆的一端连接机架,第一拉杆的另一端连接第一抱轴箱,第一拉杆沿机架的长度方向设置,且第一拉杆位于机架的中线位置;第二轮对组件用于与位于机架尾部的车轴配合,包括第二抱轴箱、第二拉杆,第二拉杆的一端连接机架,第二拉杆的另一端连接第二抱轴箱,第二拉杆沿机架的长度方向设置,且第二拉杆位于机架的中线位置。该转向架中用于传递力的第一拉杆、第二拉杆沿纵向传递力,且不易断裂,可靠性较高。
