Abstract
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).

An underfloor wheelset turning machine for reprofiling the wheel tire contours of railway wheelsets comprising a rail track, two machine units each carrying a turning support and a pair of driven friction rollers, the friction rollers being pivotable individually on the respective machine unit about a horizontal pivot axis normal with respect to the rail track, each friction roller having a peripheral surface adapted to engage a wheelset, power means for pressing the peripheral surface onto a tire wheel, the peripheral surfaces of the pair of friction rollers of one machine unit being disposed at a greater distance from the machine centerline extending in the longitudinal direction of the rail track than the peripheral surfaces of the pair of friction rollers of the other machine unit.
