Problems solved by technology
[0002] The train wheels in the prior art are ordinary wheel tires, and the wheel hub motors that are directly connected to the motors to directly drive the wheels have become particularly attractive. Because the hub motors limit the freedom of the wheels, the wheels cannot move in all directions and The driving device is automatically large, and the adaptability, driving ability and efficiency of the driving technology are not high

The invention discloses a steering mechanism used for a railway train, the railway train and a railway transportation system. The steering mechanism used for the railway train comprises a bogie, travelling devices, conductive pieces and railways; each travelling device comprises a wheel cover and a travelling wheel; the wheel covers are arranged on the bogie; electromagnets are arranged in the wheel covers; openings are formed in the lower portions of the wheel covers; the travelling wheels are spherical and are arranged in the wheel covers, and the travelling wheels partially stretch out of the openings; magnetic metal materials are arranged in the travelling wheels; the conductive pieces are connected with the wheel covers to electrify the electromagnets and enable the electromagnets to produce magnetic fields; and the traveling wheels move according to the magnetic field intensity produced by the electromagnets and the distribution directions of the electromagnets. According to the steering mechanism used for the railway train, the driving capacity and efficiency are high, and realization of steering of the traveling wheels is facilitated.
Description
Technical field [0001] The present invention relates to the technical field of vehicle engineering, in particular to a steering mechanism for a rail train, a rail train having the same, and a rail transit system. Background technique [0002] The train wheels in the prior art are ordinary wheel tires. The wheel tires are directly connected with the motor to directly drive the wheel hub motor has become particularly attractive. Because the hub motor limits the freedom of the wheel, the wheel cannot move in all directions and The driving device is automatically large, and the driving technology adaptability, driving ability and efficiency are not high. Summary of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a steering mechanism for rail trains, which has high driving capability and driving efficiency, and is beneficial to realize the steering ...
