摘要
An underfloor wheelset turning machine for reprofiling the wheel tire contours of railway wheelsets comprising two driven friction roller pairs each adapted to be pressed against a wheel tire contour of a wheelset, the friction rollers of each friction roller pair being individually connected in each case to a pivot drive and each pivotal about a pivot axis arranged parallel to the wheelset axle, is distinguished for uniform application of the friction rollers and automatic alignment of the wheelset axle in that each pivot drive (13, 14, 15, 16) comprises a pneumatic bellows cylinder (76, 77, 78, 79) for producing the pivot movement and that in each case two pivot drives (13, 14, 15, 16) associated with a friction roller pair (11, 12) are coupled to a synchronizing means (80, 81).
