The invention discloses a bogie, a railway vehicle with the same, and a railway traffic system. The bogie comprises a first horizontal wheel, a second horizontal wheel, a third horizontal wheel, a fourth horizontal wheel, a first adjusting device, a second adjusting device and a control device. The first horizontal wheel and the third horizontal wheel can be mounted on a bogie framework in a pivotrotation mode and are matched with one side of a railway, and the second horizontal wheel and the fourth horizontal wheel can be mounted on the bogie framework in a pivot rotation mode and are matched with the other side of the railway. The first adjusting device is mounted on the bogie framework to adjust the distance between the first horizontal wheel and the third horizontal wheel in the length direction of the railway. The second adjusting device is mounted on the bogie framework to adjust the distance between the second horizontal wheel and the fourth horizontal wheel in the length direction of the railway. The control device is connected with the first adjusting device and the second adjusting device. According to the bogie, turning is achieved advantageously, limitation on the turning radius is small, the strength requirement for the horizontal wheels is low, and the stability is high.
Description
technical field [0001] The invention relates to the technical field of transportation, in particular to a bogie, a rail vehicle with the bogie and a rail transit system with the rail vehicle. Background technique [0002] In rail vehicles in the related art, the running wheels and horizontal wheels are generally fixed on the bogie. When the rail vehicle turns, the whole bogie is slightly deflected by the rebound force of the rails on the horizontal wheels. [0003] However, this type of bogie cannot deflect greatly, which not only limits the turning radius, but also requires high load-carrying capacity of the track, bogie, and horizontal wheels, and there are hidden dangers in stability. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a bogie, which has the advantages of small restriction on the turning radius, low requirement on the strength ...
