| 摘要 |
A steering/lifting appliance (10) for a hydraulic or pneumatic axle compensation appliance configured as a two-circuit system, having a first external jacket tube (12), a second jacket tube (15) inserted in a pressure-tight manner in the first jacket tube (12) and supported so as to be longitudinally displaceable, a piston device (16) present in a pressure-tight manner in the second jacket tube (15) and supported so as to be longitudinally displaceable, a first closed chamber system to which admission can occur from the outside for controlling the relative displacement between the second jacket tube (15) and the first jacket tube (12) and a second closed chamber system to which admission can occur from the outside for controlling the relative displacement between the piston device (16) and the second jacket tube (15) features a torsion device (40) supported in an end region of the piston device (16) and longitudinally displaceable relative to the piston device (16), which torsion device (40) is in engagement with a second skirt profile (34) of the second jacket tube (15) surrounding the wall of the piston device (16) at least regionally, in such a way that turning of the torsion device (40) effects turning of the second jacket tube (15).
