The invention relates to a speed differential-dependent hydraulic clutch comprised of a drive housing (11), which rotates inside a housing (20), of a first shaft (21), which can be rotationally connected to the drive housing, of a second shaft (22), which is rotationally connected to the drive housing, o f a hydrostatic positive-displacement machine (1), of a friction clutch (12) f or connected the first shaft (21) to the drive housing (11), and of a piston (1 0) for acting upon the friction clutch (12). The drive housing (11) has a pressure chamber (9) and a pressure is generated in the pressure chamber (9) when a differential speed occurs. Said pressure causes the friction clutch (12) to be acted upon. A channel (13) leads from the pressure chamber to a control valve (14), which opens the way to a chamber of a lower pressure in a controlled manner. In order to enable a sensitive, precise and rapid control and adaptation of the characteristic with the lowest possible complexity, th e control valve (14) is arranged inside the drive housing (11) and/or inside t he second shaft (22), which is rotationally connected to the drive housing (11) , in a manner that is coaxial to said shaft. In addition, the control valve comprises a control element (52), which can be displaced in the direction of the axis and which is actuated by an actuator (59, 61, 62) that is fixed to the housing. |
