Example Embodiment

[0018] Please refer to figure 1 , the embodiment of the present invention provides a bogie for a railway vehicle, comprising: a wheel set 101, an axle box 102 is arranged at both ends of the wheel set 101; a frame 103 is connected with the axle box 102, and the frame 103 is connected with the A coil spring 104 with adjustable stiffness is vertically arranged between the axle boxes 102 .

[0019] In this embodiment, a magneto-rheological adjustable stiffness coil spring 104 is vertically arranged between the frame 103 and the axle box 102. Since the magnetorheological adjustable stiffness coil spring 104 can automatically change the stiffness and damping in real time, the magnetic flow The coil spring 104 with variable and adjustable stiffness can be actively adjusted according to the actual road conditions, so that it can effectively absorb the high-frequency vibration caused by the wheel-rail contact, provide a more reasonable supporting force for the railway vehicle, and mak...

Abstract

The invention provides a steering frame for a railway vehicle and the railway vehicle, wherein the steering frame for the railway vehicle comprises a wheel set and a framework. Two ends of the wheel set are respectively provided with a shaft box. The framework is connected with the shaft boxes. Magneto-rheological adjustable rigidity spiral springs are arranged between the framework and the shaft boxes vertically. The steering frame for the railway vehicle and the railway vehicle can improve riding comfort and safety of the railway vehicle.

Description

technical field [0001] The invention relates to railway vehicle equipment technology, in particular to a railway vehicle bogie and a railway vehicle. Background technique [0002] With the development of high-speed railway vehicles, people have higher and higher requirements for the running quality of vehicles. In recent years, my country's high-speed railway has developed rapidly, and higher requirements have been put forward for the running quality of vehicles. [0003] Existing railway vehicles are equipped with vibration damping devices in the suspension system of the vehicle, but because of the passive vibration damping method, the ride comfort and safety of the railway vehicles are not good, and the running quality is not high. Contents of the invention [0004] The invention provides a bogie for a railway vehicle and a railway vehicle to improve the ride comfort and safety of the railway vehicle. [0005] The invention provides a bogie for a railway vehicle, compri...
