When a railway passenger car adopts an RE type axle, the axle is too short, and the outer side of the wheel does not have enough stations for installing a driving belt wheel, so that the whole belt transmission system can only be arranged on the inner side of the wheel. Because the bogie corresponding to the inner side position of the wheel is not provided with a working position for installing the driven pulley and the generator, the driven pulley and the generator can only be fixed at the bottom of the carriage, and the arrangement mode cannot ensure that the positions of the driven pulley and the generator relative to the bogie are kept unchanged. When the bogie steers, the driving pulley can deviate from the generator relative to the driven pulley along with the rotation of the bogie, so that the working planes of the driving pulley and the driven pulley deviate, the belt is in contact with the flange of the pulley to be worn in the transmission process, and even the belt is broken.
