发明名称 Railway axle with automatic change to multiple track widths
摘要 The railway axle comprises railway wheels (1) mounted on an axle (2) by means of sliding adjustment, by virtue of the interposition of adjusted bushings (3) that are lubricated by means of grease on the inside of the wheel (1), allowing the transition from one width to another without the need to release the wheel load. The wheels (1) are immobilized on the axle (2) in terms of the axle movement thereof by means of the sleeve (5) of claws (5′) secured in rotation to the axle (2), the claws (5′) being housed in annular, trapezoidal grooves (6′) provided in rings (6) mounted on the hub (7) of the wheel (1), locking and unlocking involving a clamping sleeve (10) and pretensioned springs (11), the force of which may be overcome by a disc-like pusher (12). The railway axle furthermore includes articulated compasses (13) connected by one end to a supporting sleeve (14) of the actual articulated compasses (13) and by the other end to a base ring (9) that is hooped and secured to the axle (2).
