Friction clutch with adjustment by magneto - rheological fluid

摘要

Friction clutch for coupling and decoupling of two parts rotatable relative to one another, with a clutch carrier 11, of the outer disks 31 carries a set of louvers 29 and to the first of the parts, can be connected to a clutch hub 12, the inner disks 32 of the leaf stack 29, and can be connected with the second of the parts, as well as with an axially displaceable piston 25, which the axially on the clutch carrier 11 or on the clutch hub 12 of disks 29 is supported on or can relieve. The piston 25 is limited to one side a with the one of the coupling parts, in particular with the clutch carrier 11, circumferential annular cylindrical chamber 26, in which a with the other of the coupling parts, in particular with the clutch hub 12, of the rotor disc 27 is connected with at least one displacement blades 29 rotates. In this case, the annular cylindrical chamber 26 with at least a large proportion of magneto - of rheological liquid is filled and sealed from the outside. The piston 25 consists of ferromagnetic material, and opposite to the piston 25 is provided on the other side of the annular cylindrical chamber 26 of a controllable magnetic coil 24 is arranged, which a magnetic flux through the chamber 26 and the piston 25 can be produced.
