Railroad bogies with gauge change systems, and railcars with such railroad bogies

摘要

PROBLEM TO BE SOLVED: To provide a railroad bogie provided with a gauge changing system, and a railroad vehicle provided with such a bogie. SOLUTION: A set of first wheels of a bogie 100, which are movably connected to each other at least along a first axis Y in the lateral direction with respect to a traveling direction X of the bogie along a railroad track 110. The first half frame 10 supporting the first half frame 10 and the second half frame 20 supporting the second wheel set 12 and the first and second halves mounted and locked on the first and second half frames. Lateral movement possible between the lowered position where the frame is at the first mutual distance corresponding to the first rail gauge and the raised position where the frames are unlocked from the first and second half frames and lifted up. A gauge change system suitable for interacting with bolsters and gauge change equipment located along railroad tracks and equipped with first and second support rails 2, 3 and multiple guide rails intervening between them.
