Description

Suspended monorail vehicle drop-off connection structure and suspended monorail vehicle

Technical field

The invention relates to a suspended monorail vehicle drop-off connection structure and a suspended monorail vehicle, belonging to the field of monorail rail vehicles.

Background technique

The hanging monorail body and bogie connection technology is the key technology to realize the suspension operation of the vehicle. At present, there are only three technical connection methods in the world. They are the Wuppertal air-rail vehicles in Germany and Dusseldorf, Germany. Air track vehicles and Japanese Chiba air rail vehicles.

The Wuppertal monorail vehicle body and the bogie are rigidly connected. There is no relative movement between the car body and the bogie. The vehicle suspension changes to realize the vehicle's floating and sinking movement. When the current rear bogie suspension height is inconsistent, the vehicle realizes nodding movement; the wheel The normal change with the contact surface of the rail realizes the lateral swing of the vehicle, but the body and the bogie cannot realize the roll motion of the vehicle body and the bogie; other degrees of freedom are similar to those of the subway vehicle. With this drop-off connection method, since the drop-off connection structure is rigidly connected with the vehicle body and the bogie, when the vehicle nods, the connection structure needs to resist the movement of the nodding head, the structure needs to bear a large internal stress; and at the same time, due to the lateral swing of the vehicle, The normal and contact points of the wheel-rail contact surface are constantly changing. The wheel-rail must be rigidly freely contacted, that is, the steel wheel rail. The structure of the wheel-rail noise and vibration is large; the angle between the wheel and the rail cannot be oscillated, and the vehicle body The relative motion with the rail is completely free to swing, and the dynamic limit of the vehicle is large, which requires more wiring space and engineering cost.

The body of the monorail vehicle in Düsseldorf, Germany is connected with the bogie by an air spring. The lower surface of the roof beam of the car body is equipped with an air spring. The lower surface of the air spring is equipped with an air spring connecting beam for connecting the air springs on both sides of the vehicle. Connected vertically to the connection of the bogie at the center of the air spring connection bolster The connecting rod and the air spring are connected by a rotating pair, and the axis of the rotating pair is parallel with the longitudinal direction of the vehicle body, and a shock absorber is arranged between the connecting rod and the air spring connecting the bolster for buffering the rolling motion of the vehicle body and simultaneously connecting A rigid connecting rod is provided between the rod and the cross member beam for transmitting longitudinal force. When the vehicle is nodding, the connection structure needs to resist the movement of the nodding head, and the structure needs to bear a large internal stress. At the same time, due to the addition of the shock absorber, the shock absorber can relieve the drastic change of the movement when the vehicle swings laterally. , to improve the comfort; but because the buffer can not limit the swing angle, the relative movement of the car body and the bogie is completely free to swing, the dynamic limit of the vehicle is large, requiring more line space and engineering cost.

Japan's Chiba air-rail vehicle drop-off connection structure is consistent with the Wuppertal air-rail structure, and is also a rigid connection. In order to use the rubber wheel to simultaneously realize the lateral swing of the vehicle, the bogie only has a guide wheel, and no stabilizer wheel is provided. When swinging, the bogie oscillates with the body. With this drop-off connection method, since the drop-off connection structure is rigidly connected with the vehicle body and the bogie, when the vehicle nods, the connection structure needs to resist the movement of the nodding head, and the structure needs to bear a large internal stress; when the vehicle swings laterally, the movement The angle can not be limited, the relative movement of the car body, the bogie and the track beam is completely free to swing, the dynamic limit of the vehicle is large, and the need for larger line space and engineering cost; since there is no swing buffer, the sharp movement cannot be relieved, and the comfort is improved. Not too good.
