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. In order to make possible a sensitive, precise and rapid control and adaptation of the characteristic with as little outlay as possible, the control valve (14) is arranged in the drive housing (11) and/or, in the second shaft (22), which is connected in a rotationally fixed manner to the drive housing (11), is arranged coaxially with said shaft, and has a control element (52) which can be displaced in the direction of the axis and is actuated by an actuator (59, 61, 62) which is fixed on the housing.
