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). By including a bolster and an extra suspension on the basis of the conventional two suspensions, the disclosed bogie can achieve separation of the functions, so that the tertiary suspension only handles the transverse displacement, and the secondary suspension only handles the rotation, thereby further increasing the relative displacement and rotation angle between the vehicle body and the bogie when the vehicle negotiates a curve.
