Wheelset press

摘要

In the case of a wheelset press (100) for pressing wheels, brake discs or the like onto or off of wheelset shafts (RA) of rail vehicles, two piston-cylinder units (3, 4) arranged fixedly on a common straight line (S) and directed towards each other are provided for producing the necessary pressing pressure and, if appropriate, for moving the wheelset shaft in the longitudinal direction of the wheelset shaft to perform the pressing-on or pressing-off operation. To transmit the pressing force onto the facing end of the wheelset shaft, pressing rams (7, 8) are provided on the piston-cylinder units. At least one pressing abutment (17A, 17B) for supporting the wheel, a brake disc or the like during the pressing operation is designed in such a way that it can be brought into its supporting position by a relative movement with respect to the wheelset shaft transversely in relation to the longitudinal direction of the latter, and is otherwise outside the pressing area. The at least one pressing bearing (17A, 17B) can be fixed in various positions along the wheelset shaft. For this purpose, connecting columns (5, 6) fixedly arranged between pressing tie bars (1, 2) have axially spaced-apart abutments. In order to achieve a compact overall form, as one of the aims, the abutments are provided on the connecting columns (5, 6) as sliding guides (20) for directly receiving the at least one pressing abutment (17A, 17B), which allow the pressing abutment to be moved from a position outside the pressing area into a tilt-free supporting position for the pressing-on or pressing-off operation by closing.
