Abstract (en)
A variable-wheel-gage bogie has axles (24), journal box beams (29) bearing the body weight of a wheeled vehicle, journal boxes (50) axially slidably fitted in the journal box beams (29), respectively, axle sleeves (30) put on each axle (24) and supported in journal bearings (51) on the journal boxes (50), respectively, wheels (36) fixedly joined to the axle sleeves (30), respectively, and locking mechanisms (60) for locking the wheels (36) so as to be axially immovable. The locking mechanisms (60) are disengaged by unlocking rails (73) extended along body support rails (70) that bear the body weight of a wheeled vehicle and are engaged by locking rails (74) extended along the body support rails (70). The locking mechanisms (60) can be operated in a state here the journal box beams (29) are supported on the body support rails (70) and the axle (24) is not loaded. Thus, the locking mechanisms (60) can be surely engaged to lock the wheels (36) so as to be axially immovable and can be surely disengaged to permit the axial movement of the wheels (36) for wheel-back-gage change.
