Motive axle system with movable wheels for railway vehicles

摘要

A motive axle system with movable wheels for railway vehicles comprising a short axle (E) whose journal (1) is mounted on a first bearing (2); a tubular part (4) which has a wheel (R) at one of its ends and has an end area with an outer straight-toothed gearing (5'); a second bearing (7) attached to the tubular part (4), with axial bearings (8) on each side of the same; a box (9) which houses said bearings (7, 8), provided with protuberances (10) for co-operating with the rods of a bolt which immobilises the wheel (R) in positions corresponding to the different track gauges; and a hollow axle floating system (H) to transmit the drive of a traction motor by means of a bevel gear assembly and thus to make the wheel (R) turn.
