Wheel set for rail vehicles

A wheel set for rail vehicles, comprising an axle having a longitudinal axis, two wheels secured to said axle, said axle being divided into a first axle section and a second axle section, clutch means interconnecting said first and second axle sections for selectively permitting said first and second axle sections to rotate at different r.p.m.s for permitting a differential r.p.m., one of said axle sections having a hollow end forming a radially outer axle section end, the other of said axle sections having a radially inner axle stub forming a radially inner axle section end fitting into said hollow radially outer axle section end, first bearing means (6) interposed between said hollow radially outer axle section end and said radially inner axle stub for permitting relative rotation while preventing axial movement between said axle sections, said clutch means comprising a radially inner clutch component (7.2) and a radially outer clutch component (7.1), first means (7.5) rigidly securing said radially inner clutch component on said radially outer axle section end, second means for rotatably supporting said radially outer clutch component on said radially outer axle section end and for rigidly connecting said radially outer clutch component to said other axle section outside said radially inner axle stub, whereby both clutch components are mounted on said radially outer axle section end.
