摘要： A central traction device for a straddling monorail train comprises a traction pin (9) and a traction beam (10). A central sleeve (22) is disposed at the center of the traction beam (10), the traction pin (9) is mounted in the central sleeve (22), the inner chamber of the central sleeve (22) is of a tightened-waist structure having bigger apertures at the upper end and the lower end and a smaller aperture at the middle part, a biconical inclined plane is formed, and an elastic rubber sleeve is disposed between the inner wall of the central sleeve (22) and the traction pin (9). The device has a simple and compact overall structure, and helps to implement connection and separation between a vehicle body and a bogie; by means of cooperation among the traction beam (10) of the tightened-waist structure, the elastic rubber sleeve and a traction rubber pile (11), transmission of traction force and braking force during operation of a vehicle in function is better implemented, the change of load in a transverse direction and a longitudinal direction as well as loading can also be better adapted, requirements of a larger traction force and a larger load change can be satisfied, and the stability and the comfort during operation of the vehicle are greatly improved.

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.

摘要： The present disclosure relates to a suspension traction device of a low floor articulated rail vehicle, which comprises swing bolster mechanisms, traction rod mechanisms, primary springs and secondary springs. Two swing bolster mechanisms and two traction rod mechanisms are provided, two swing bolster mechanisms are provided respectively in the middle of two groups of wheel-sets. Each swing bolster mechanism is connected to the frame by a set of traction rod mechanisms and is connected to the vehicle body by means of a rotary mechanism. The disclosure has the advantages of simple and compact structure and light weight. It not only realizes the transmission of the traction and the braking force when the vehicle is running, carries the vertical, horizontal and vertical load, which greatly improves the small curving performance of the vehicle, but also reduces the height of the floor surface and the driving performance of the vehicle has also been greatly improved.
