简介：Europe invented the bogie. The front two wheels of a four-wheeled vehicle are mounted on one frame, the rear two wheels are mounted on another frame, and the rear frame is connected to the front frame by a vertical shaft. It is actually a combination of two two-wheelers. In this way, this eternal problem has been cleverly solved.
