Problems solved by technology

Due to the small space size of the micro-rail vehicle, it is not possible to use the complex suspension damping mechanism of the suspended monorail vehicle
[0003] The structure of the suspension device of the existing micro-rail vehicle is simple, the boom and the carriage are directly connected by bolts, and the relative swing between the carriage and the running part is realized by the pin shaft, so the existing micro-rail vehicle cannot effectively block the vibration generated by the running part The problem of transmission to the carriage makes the existing micro-rail vehicles have poor vibration damping effect and cannot effectively limit the free swing of the vehicle
