摘要： Provided are a bogie and a rail vehicle. The bogie comprises: two wheel sets arranged in parallel, the wheel set comprising an axle (11) and two wheels (12) symmetrically arranged on the axle (11); two side beams (2) spanning over the two wheel sets, the two side beams (2) being parallel with each other; axle boxes (13) arranged on the wheel sets, located under the side beams (2), and configured to support the side beams (2); two connection bases (3) each arranged at a middle part of one side beam (2); and a traction device (4) connected between the two connection bases (3), the traction device (4) being further configured to be connected to a vehicle body. The bogie and the rail vehicle can reduce the assembly difficulty of the bogie.

摘要： A magnetic suspension bogie, the bogie comprising a upper frame located at the upper portion, two lower frames located at the lower portion, a suspension device and a track sensing device, wherein the upper frame and the lower frames are hinged and connected by means of a connecting device. By means of using a bearing hinge structure to connect the upper frame and the lower frames, it is not necessary to specially provide a separate steering mechanism; thus, a plurality of functions are comprised, while the structure is at the same time simplified. The present invention also relates to is a magnetic suspension train.

摘要： A bogie, including a frame (1) and a bolster (2), the frame (1) including two parallel side beams (11), and a cross beam (12) coupled to the middle of the side beams (11), wherein a primary suspension is arranged between an end of the side beam (11) and an axle box (31), a secondary suspension is arranged between the below of the bolster (2) and the cross beam (12), and a tertiary suspension coupled to a vehicle body is arranged above the bolster (2). The disclosed bogie is provided with a bolster, and on the basis of the original two suspensions, another suspension is added beneath the bolster and between the bolster and the cross beam to achieve separation of the functions, so that the tertiary suspension above the bolster only functions to handle the transverse displacement, and the secondary suspension beneath the bolster only functions to handle the rotation, thereby further increasing, when the vehicle negotiates a curve, the relative displacement and rotation angle between the vehicle body and the bogie, improving curve negotiating for the vehicle. Combining three suspensions can create good vibration isolation and noise reduction, effectively attenuating the vibration between the wheel and the rail, and improving riding comfort.
