Claims

[Scope of Claim for Utility Model Registration] 1. A radial bogie that rotates two wheel shafts disposed at the front and rear of the bogie to face the center of the curve of the track when the vehicle passes through a curved track,
A hydraulic cylinder is provided between the bogie frame that constitutes the bogie and the axle box that holds the wheel axle, and its expansion and contraction action acts in the direction of rotating the wheel axle with respect to the bogie. A radial truck comprising a control valve that expands and contracts the hydraulic cylinder by controlling the hydraulic pressure supplied to the hydraulic cylinder according to the direction and amount of angular displacement between the two. 2 When the vehicle passes through a curved track, the two wheelsets located at the front and rear of the bogie are rotated to face the center of the curve of the track, depending on the angular displacement that occurs between the car body and the bogie. In a radial bogie to be moved, a hydraulic cylinder is disposed between the car body and the bogie, and its expansion and contraction action acts in the direction of rotating the bogie with respect to the car body. A radial truck characterized by comprising a control valve that expands and contracts the hydraulic cylinder by controlling the hydraulic pressure supplied to the hydraulic cylinder according to the amount of angular displacement.
