Liquid friction clutch

摘要

A liquid friction clutch (1) having a housing (2, 3), a clutch disc (4)—rotatable relative to the housing (2, 3) and which is rotatably arranged on an end (5) of a shaft (6) which is mounted centrally within the housing (2, 3), which shaft (6) bears on its other end (8) a driveable active element (7). A working chamber (9) is positioned between the housing (2, 3) and the clutch disk (4). A storage chamber (10) is provided for the clutch fluid. A supply duct (11) leads from the storage chamber (10) to the working chamber (9). A stationary clutch part (13) relative to which the housing (2, 3) is rotatable, wherein a rotatably mounted pump element (14) is provided which, with the housing (2, 3), defines a shear gap (12).

主权项

1. A liquid clutch comprising:
a stationary member; a housing member that is rotatable about an axis relative to said stationary member; a clutch disk positioned in said housing member, said clutch disk being rotatable about said axis relative to the housing member; a shaft having a first end and a second end, the first end being coupled to the clutch disk for rotation therewith; a driveable active element that is coupled to the second end of the shaft for rotation therewith; a working chamber positioned in said housing member; a storage chamber for clutch fluid in said housing member; a supply duct coupling said storage chamber and said working chamber in fluid communication; a PUMP element that is rotatable relative to said stationary member and said housing, said PUMP element cooperating with said housing to define a shear gap; and a brake device for braking said pump element.
