摘要： The present application relates to the field of rack vehicles, and provides a bogie, a vehicle body, and a rack vehicle. The bogie comprises: a bogie body; two locomotion teeth provided on the bogie body in the length direction of the bogie body; two driving members respectively in transmission connection with the two locomotion teeth by means of transmission devices, the transmission devices being respectively provided on two sides, facing away from each other, of the two locomotion teeth in the width direction of the bogie body; and a secondary vibration damping device mounted on the bogie body to be connected to a vehicle body, the secondary vibration damping device comprising air springs. According to the bogie, the locomotion structure of the bogie can be more stable, such that the operation stability of the vehicle is improved. The vibration damping effect between the vehicle body and the bogie body is further improved, such that the comfort of the vehicle is improved.
