  • Patent number: 11208123
    Abstract: Disclosed is a frame for a bogie, comprising two side beams parallel to each other and a transverse beam connected to the middles of the side beams, wherein the middle of the transverse beam is provided with a traction pin hole, and an upper surface of the transverse beam is provided with a plurality of mounting seats for mounting a secondary suspension. The frame of the present invention is provided with a traction pin hole at the center of the transverse beam so that the transverse beam is connected to the bolster so as to bear a traction force, and a plurality of mounting seats for mounting the secondary suspension are arranged on an upper surface of the transverse beam, so that the secondary suspension can bear a rotation movement between the bogie and the vehicle body to improve curve passing capability of the vehicle.
