Abstract

The embodiment of the invention provides a bogie. The bogie comprises a framework and a secondary suspension device, and the secondary suspension device is arranged on the framework; the framework comprises a rigid framework main body and a composite material layer which is at least fixed to the position, used for fixing a bogie mounting base, in the outer surface of the framework body, and the composite material layer is used for separating the bogie mounting base from the framework body; and the framework serves as an installation foundation of the bogie, the bogie installation base is used for installing all components of the bogie, and the top of the secondary suspension device is used for being connected with a vehicle body. According to the embodiment of the invention, the technical problem that vibration between a framework in the bogie and components of the bogie is large is solved.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, and in particular, relates to a bogie. Background technique [0002] Rail vehicles are an important transport link connecting cities. A rail vehicle mainly includes: a car body and a bogie arranged under the car body. The bogie is used to carry the car body and realize the running and steering functions. [0003] The traditional bogie mainly includes: frame, wheel set, traction device, braking device and buffer device, and the power bogie also includes driving device. Wherein, the frame is the main frame of the bogie, and many parts of the bogie are fixed to the frame through metal bogie mounts. The traditional frame is an H-shaped frame formed by welding stainless steel materials. The rigid connection between the parts of the bogie and the frame leads to higher vibrations of the bogie, which in turn leads to less comfort of the rail train. [0004] Therefore, the large vibrat...
