The auxiliary frame type radial bogie is one of the main type bogies of railway freight cars in China, and is a technical result of absorbing innovation by introducing the Scheffel bogie technology in south Africa in China. The bogie has relatively high shearing rigidity and relatively low bending rigidity. Wherein, the auxiliary frame is generally arranged at two ends of the swing bolster, and the connecting rod passes through a hole in the middle of the swing bolster. When the auxiliary framework type radial bogie runs linearly, the operation stability is good; when the wheel passes through the curve, the front wheel pair and the rear wheel pair are located at radial positions, and the wheel track attack angle can be greatly reduced. Thereby effectively reducing the power of the wheel rail, improving the curve passing performance of the vehicle, reducing the abrasion of the wheel rail and reducing the power consumption.
The Scheffel bogie in south Africa is mainly applied to a 1067mm narrow-gauge line; the auxiliary frame type radial bogie in China is mainly applied to a 1435mm standard track distance line. From the 90 s in the 20 th century, China developed auxiliary frame type radial bogie series products with different structural types and different axle weights successively, and exported the auxiliary frame type radial bogie series products to countries such as Australia, Venezuela, Mongolia and the like in batches, wherein the track gauges are 1435mm and 1520 mm.
