Specifically, in the present embodiment, the longitudinal beam mechanism 5 is located at the lowermost layer of the entire suspension device as the main support mechanism. The two longitudinal beam mechanisms 5 are symmetrically arranged at the left side and the right side. A plurality of anti-rolling decoupling mechanisms 6 which are arranged in parallel are arranged between the two longitudinal beam mechanisms 5. The number of the anti-rolling decoupling mechanisms 6 can be determined according to the length of the longitudinal beam mechanism 5, and usually two anti-rolling decoupling mechanisms 6 can meet the requirement. The driving mechanism 7 is arranged on the longitudinal beam mechanism 5 and used for providing driving force for the running process of the magnetic suspension train. The air spring suspension mechanism 9 is fixed on the top of the longitudinal beam mechanism 5. And a traction mechanism 8 is arranged between the air spring suspension mechanism 9 and the longitudinal beam mechanism 5 and is used for transmitting traction force in the running process of the magnetic suspension vehicle.

More specifically, in the present embodiment, the longitudinal beam mechanism 5 includes two upper bracket arms 501, two lower bracket arms 502, a motor beam 503, and an electromagnet 504. As shown in fig. 3, the electromagnet 504 is located at the bottommost portion of the longitudinal beam mechanism 5 as an important component for providing levitation force. Two lower bracket arms 502 are respectively fixed at two ends of the outer side of the electromagnet 504. Each lower bracket arm 502 corresponds to one upper bracket arm 501. The two upper supporting arms 501 are both located above the electromagnet 504, and the ends of the upper supporting arms 501 are bent downwards and are fixedly connected with the top of the lower supporting arm 502. A track gap is left between the upper bracket arm 501 and the electromagnet 504 for penetrating the track. The motor beam 503 is fixed between the two upper bracket arms 501, and the length direction of the motor beam 503 is consistent with the length direction of the electromagnet 504. A mounting gap is left between the motor beam 503 and the electromagnet 504 for mounting the driving mechanism 7. The upper bracket arm 501, the lower bracket arm 502, the motor beam 503 and the electromagnet 504 can be connected by bolts.

The anti-rolling decoupling mechanism 6 comprises two anti-rolling beam plates 601, an anti-rolling suspension rod 602 and two anti-rolling pull rod seats 603 as a component for connecting the left and right side longitudinal beam mechanisms 5. As shown in fig. 4, two anti-roll bar holders 603 are respectively fixed on two opposite motor beams 503. Each anti-roll pull rod seat 603 is connected with the end of one anti-roll beam plate 601 through a connecting pin. The two anti-rolling beam plates 601 are arranged in a vertically staggered manner, and the two anti-rolling beam plates 601 are connected through an anti-rolling suspension rod 602. In this embodiment, two anti-roll beam panels 601 are fixed together by an anti-roll boom 602 for use in a group. In order to prevent the magnetic suspension vehicle from being influenced by factors such as track irregularity, each suspension device can be provided with two anti-rolling decoupling mechanisms 6, so that the two anti-rolling decoupling mechanisms 6 and the two longitudinal beam mechanisms 5 form a rectangular structure, and the condition that the left longitudinal beam mechanism 5 and the right longitudinal beam mechanism 5 deform in a splayed shape is prevented. In addition, in this embodiment, the joint bearing is disposed in the anti-rolling rod seat 603, so that the anti-rolling beam plate 601 can horizontally rotate in the anti-rolling rail seat through the joint bearing, and the magnetic levitation vehicle can turn more flexibly.

The drive mechanism 7 comprises a linear motor which can be fixed by means of screws in the mounting space between the motor beam 503 and the electromagnet 504. Meanwhile, the distance between the linear motor and the track can be adjusted by arranging the adjusting pad, so that the linear motor and the track are prevented from being scratched during the running of the magnetic levitation vehicle.

As shown in fig. 5, wherein the frame end tie rod seat 803 is fixed to the top of the motor beam 503. The traction force can be transmitted between the frame end pull rod seat 803 and the motor beam 503 through the small clearance fit of the cylindrical pin and the hole. The vehicle body end tie rod seat 801 may be secured to the side of the air spring suspension mechanism 9 adjacent the frame end tie rod seat 803 by bolts and cylindrical nuts. One end of the drag link 802 is connected to the frame end link base 803, and the other end is connected to the body end link base 801. When the magnetic suspension vehicle runs, the traction pull rod 802 can provide the longitudinal traction force of the magnetic suspension vehicle.

The air spring suspension mechanism 9 is fixed in the middle of the top of the motor beam 503 to ensure the overall stability of the suspension device. The air spring suspension mechanism 9 comprises an air spring, a height valve and a height valve adjusting rod. Wherein, a vehicle body connecting seat 901 is arranged at the top of the air spring. The vehicle body connecting base 901 is provided with a cylindrical pin and a connecting block, which can be connected with the vehicle body of the magnetic suspension vehicle and can also be connected with other components such as a vehicle body end pull rod base 801 and the like, so that the connection reliability is ensured. In addition, in this embodiment, a cross line stopper is provided in the air spring. The transverse line stopping device can be used for limiting the rotating angle of the magnetic suspension vehicle body, and preventing the magnetic suspension vehicle body from deviating too much from the suspension device in the turning process to influence the safety.

Further, the suspension device provided by the embodiment further comprises a skid. The skid specifically includes a vertical skid 1001 and a lateral skid 1002. As shown in fig. 6, the vertical skid 1001 is disposed on the lower surface of the front end of the upper supporting arm 501, and is used for supporting the vehicle body after the power failure of the magnetic levitation vehicle, and the vertical skid 1001 contacts the track first after the power failure of the levitation vehicle, so as to protect the levitation device from the impact of the track. The transverse skid 1002 is arranged in a mounting gap between the motor beam 503 and the electromagnet 504, and the front end face of the transverse skid 1002 faces the track, so as to prevent the suspension device and the track from generating large deviation and influence the running safety of the magnetic suspension train.

In addition, the suspension apparatus proposed in this embodiment further includes an electric supporting wheel mechanism 11, and as shown in fig. 6, the electric supporting wheel mechanism 11 is disposed on the lower surface of the front end of the upper bracket arm 501. The electric supporting wheel mechanism 11 comprises a roller, and the electric supporting wheel mechanism 11 is used for connecting with an external vehicle and enabling the roller to roll on a track under the dragging of the external vehicle. The device can be used for rescuing the trailer when the magnetic levitation vehicle breaks down.
