Embodiment Construction

[0020] The core of the present invention is to disclose a rotatable frame, which can automatically eliminate the uneven distribution of wheel weight inside the bogie, realize low wheel weight transfer, improve the adhesion utilization rate, reduce wheel wear and make it uniform.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] see Figure 1-Figure 3 , figure 1 Schematic diagram of the structure of the rotatable frame provided by the embodiment of the present invention; figure 2 for figure 1 Sect...

Abstract

The invention discloses a rotatable frame. A split rotatable structure is adopted, a T-shaped beam and a straight beam of the frame are connected through a rotating device, when wheel loads of a front axle and a rear axle of a bogie are inconsistent, and additional torque is generated, the straight beam and the T-shaped beam can mutually rotate until the wheel loads are balanced, and therefore the wheel loads are automatically and evenly distributed. The invention further provides a rail car with the rotatable frame, low wheel load transferring can be achieved, the adhesion utilization rate can be improved, wheel abrasion can be reduced, and is homogenized, development of car traction performance can be facilitated, meanwhile, the running performance of the car is improved, and the wheel rail abrasion is reduced.

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...
