Abstract

The invention relates to the technical field of rail transit, and provides a radial bogie and a rail vehicle. The radial bogie includes a first framework, a second framework, a secondary damping device and a guide component, wherein a first wheel set is mounted on the first framework; the second framework is rotatably connected with the first framework and is provided with a second wheel set; thesecondary damping device is mounted on the first framework and the second framework; and the guide component is installed on a vehicle body of the railway vehicle, and the secondary damping device makes contact with the guide component and can slide along the guide component along with relative rotation between the first framework and the second framework. According to the radial bogie and the rail vehicle, at least swinging and fluctuation of the bogie in the running process can be improved, and therefore the snakelike running stability and the curve passing performance of the radial bogie can be better balanced.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a radial bogie and a rail vehicle. Background technique [0002] The bogie's snaking running stability and curve passing performance are a pair of contradictions. The radial bogie technology can solve this contradiction well. The radial bogie can reduce the abrasion of the wheel rim and the rail while ensuring sufficient snaking motion stability, and is suitable for the operation requirements of high-speed and heavy-duty vehicles on small-radius curves. . Although the radial bogie can solve the contradiction between serpentine running stability and curve passing performance, there is still room for further improvement in the radial bogie used in rail vehicles so as to better balance the above-mentioned performances. Contents of the invention [0003] Aiming at the defects existing in the prior art, the embodiment of the present invention provides a radial bogie an...
