Three-way vehicle suitable for narrow roadway

Abstract

The invention relates to the technical field of three-way vehicles, and particularly discloses a three-way vehicle suitable for a narrow roadway, the three-way vehicle comprises a vehicle body, a driving wheel set, a guide wheel set and a distance measuring assembly, two guide rails are arranged on the two sides in the narrow roadway respectively, and the driving wheel set comprises a driving wheel located at the bottom of the front end of the vehicle body; the guide wheel set comprises a plurality of guide wheels symmetrically arranged on the two sides of the vehicle body and driving units in one-to-one correspondence with the guide wheels, and the distance measuring sensors comprise the first distance measuring sensor and the second distance measuring sensor. The distance between the two sides of the vehicle body and the two guide rails can be measured through the two first distance measuring sensors, if the vehicle body is not centered, the driving wheels can be controlled to steer until the vehicle body is centered and then normally runs, and the vehicle body can be mechanically limited through the guide wheels on the two sides of the vehicle body; meanwhile, due to the fact that a certain gap is guaranteed between the guide wheel and the guide rail, abrasion of the guide wheel and the guide rail can be avoided.
