A speed-difference-dependent hydraulic clutch comprises a drive housing ( 11 ), which rotates in a housing ( 20 ), a first shaft ( 21 ) which can be connected in a rotationally fixed manner to the drive housing, a second shaft ( 22 ) which is connected in a rotationally fixed manner to the drive housing, and furthermore a hydrostatic displacement machine ( 1 ), a friction clutch ( 12 ) for connecting the first shaft ( 21 ) to the drive housing ( 11 ), and a piston ( 10 ) for acting on the friction clutch ( 12 ), the drive housing ( 11 ) having a pressure space ( 9 ) and where a pressure is produced in the pressure space ( 9 ) when a difference in speed occurs in the pressure space ( 9 ), this pressure giving rise to action upon the friction clutch ( 12 ), and a passage ( 13 ) leading from the pressure space to a control valve which opens up the route to a space of lower pressure in a controlled manner. |
