ABSTRACT:
An underfloor wheelset turning machine is described for reprofiling the wheel tire contours (34) of railway wheelsets (6). The machine comprises two turning supports (27, 28) and four driven friction rollers (9, 10,11,12), of which each pair of rollers is adapted to be pressed with in each case a peripheral face (57,58, 60,61) onto a wheel tire. The friction rollers (9,10,11,12) are pivotal individually each about a pivot axis (50,51,52,53) disposed parallel to the wheelset axle (41). The peripheral faces (60, 61) of two friction rollers (11,12) are disposed further from the wheelset center (64) compared with the peripheral faces (57, 58) of the other two friction rollers (9, 10).
