Abstract
Description
Technical Field
[0001] The utility model relates to the field of RGV, in particular to a ring-shaped double-track RGV walking structure. Background Art
[0002] RGVs are widely used as track-guided vehicles. However, most existing RGVs lack sliding mechanisms or side guides on their inner track. They rely solely on automatic steering with universal follower wheels to maintain contact with the inner track surface. This results in unstable contact between the wheels and the track surface, making the RGV unstable and limiting its speed. For example, an RGV with publication number CN210682191U utilizes guide wheels to enhance its stability, but its universal follower wheels are fixed in position. Because the distance between the universal drive wheel and the universal follower wheel is fixed, this can cause the wheels to detach from the inner track surface when cornering, resulting in vehicle instability.
