Railway vehicle steering truck

摘要

In the present invention, even if a drop-preventing part is not newly installed, if a steering device has broken, contact with or dropping onto the raceway surface by the broken constituent component is prevented. A steering truck disposes a steering device (1) wherein a steering link (1b) rotatably connected to an axle box (4) that supports a steering shaft (2), and a connecting link (1c) rotatably connected to a bolster (5) are each rotatably connected to a steering lever (1a) rotatably connected to a truck frame (3). The length (A1 or A2) from one center of rotation to the other tip of the steering link (1b) is caused to be shorter than the radius (B) of a wheel that has reached the wear limit.
