A locking device (100, 200, 300) for an axle (151, 251, 351) is provided, having a receptacle (245) for an axle (151, 251, 351) or having an axle (151, 251, 351), having a cylinder (110, 210, 310) for a fluid, which cylinder (110, 210, 310) has a cylinder wall, having a piston (120, 220, 320) which is arranged in the cylinder (110, 210, 310) and is sealed against the cylinder wall at least in sections or at points, with the result that the interior of the cylinder (110, 210, 310) is divided into a first volume (111, 211, 311) and a second volume (112, 212, 312) which is separated from the first volume (111, 211, 311) by the piston (120, 220, 320), having a mechanical connection (140, 240, 340) between the piston (120, 220, 320) on one side and the receptacle (245) of the axle (151, 251, 351) or the axle (151, 251, 351) on the other side, with the result that the position of the piston (120, 220, 320) in the cylinder (110, 210, 310) defines the orientation of the receptacle (245) for the axle (151, 251, 351) or the orientation of the axle (151, 251, 351) and vice versa, wherein the first volume (111, 211, 311) is connected to the second volume (112, 212, 312) via a line system (130, 230, 330) which has a line section (131, 231, 331), in which a valve (132, 232, 332) is arranged. |
