Abstract

The invention discloses a bogie, a rail vehicle with the same and a rail transit system. The bogie comprises a bogie frame, a plurality of first horizontal wheels and a plurality of second horizontal wheels. The bogie frame is provided with a rail concave part suitable for straddling on a rail. The first horizontal wheels are pivotally mounted on the bogie frame, suitable for being matched to one side of the rail and coaxially arranged at intervals in the up-down direction. The second horizontal wheels are pivotally mounted on the bogie frame, suitable for being matched to the other side of the rail and coaxially arranged at intervals in the up-down direction. According to the embodiment of the invention, the bogie can improve stability of the whole vehicle and lower the overturning risk of the rail vehicle during turning and high-speed travelling.

Description

Technical field [0001] The present invention relates to the field of transportation technology, and in particular to a bogie, a rail vehicle with the bogie, and a rail transit system with the rail vehicle. Background technique [0002] Rail transit systems such as straddle monorail trains are composed of rail vehicles and rails. The rail vehicles include a car body and a bogie. The car body is drawn by a bogie straddling the rail, and the bogie drives the car body to travel and turn. However, the rail transit system in the related technology has poor stability, and rail vehicles are prone to overturning when cornering or driving at high speed. Summary of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a bogie, which can improve the stability of the entire vehicle and reduce the risk of overturning when the rail vehicle is corner...
