Description

Technical Field

[0002] With the rapid development of modern industry and transportation, rail transport vehicles, as an efficient and stable means of transportation, have been widely used in a variety of fields, including railway equipment maintenance, infrastructure construction, large-scale entertainment facilities, and agricultural mechanization. However, traditional rail transport vehicles often suffer from problems such as inflexible steering, poor adaptability, and complex operation. These problems are particularly prominent in complex and changing operating environments. First, traditional rail transport vehicles mostly use a fixed wheelbase design, which makes it difficult to adapt to changes in tracks with different curvature radii. This results in greater lateral friction between the tires and the track when driving on curves, which not only increases energy consumption and wear, but also reduces driving stability and safety.

[0003] Secondly, while some existing steerable rail transport vehicles have solved the steering problem to some extent, they are often complex and costly, and their steering precision and response speed cannot meet practical requirements. The limitations of existing technology are particularly evident in applications that require frequent steering and precise control, such as remote-controlled mobile transport vehicles for agricultural field operations.
