Abstract

The invention discloses a rotatable frame, which adopts a split rotatable structure, and the T-beam and the straight beam are connected by a rotating device. The straight beam and the T-beam can rotate each other until they reach a balance, so that the wheel weight can be evenly distributed automatically. The present invention also provides a rail vehicle using the above-mentioned rotatable frame, which can realize low wheel weight transfer, improve the adhesion utilization rate, reduce wheel wear and make it uniform, which is beneficial to the traction performance of the vehicle and is also beneficial Improve vehicle running performance and reduce wheel and rail wear.

Description

technical field [0001] The invention relates to the technical field of rail vehicle bogies, in particular to a rail vehicle and a rotatable frame thereof. Background technique [0002] The frame is the main body of the rail vehicle bogie and the basis for the installation of all parts of the bogie. [0003] Uneven wheel weight distribution occurs inside the rail vehicle bogie, which is mainly caused by factors such as traction, component manufacturing errors, uneven lines, and track distortion. [0004] According to the manufacturing method, there are currently two types of frames commonly used: casting type and welding type. However, no matter the casting type or the welding type, they are all integral structural frames without the ability to automatically adjust the wheel weight. The uneven distribution of wheel weight directly affects the traction performance of the vehicle, and also affects the running performance and wheel-rail wear of the vehicle. [0005] Therefore...
