Abstract: An electromagnetically actuatable clutch for a water pump in a cooling water circuit of an internal combustion engine, having a drive wheel rotatably mounted relative to the water pump, and an armature disk, which interacts with a coil. The armature disk and a functional component of an eddy current clutch are connected to the drive wheel so that the drive wheel, armature disk and first functional component run synchronously when they rotate. The armature disk can be moved axially with the first functional component by energizing the coil. A second functional component of the eddy current clutch is provided arranged in a fixed fashion on a shaft coupled to the water pump. A friction mechanism is provided between the first and second functional components to provide a frictional locking engagement between the two functional components that is released by energizing the coil.

Abstract: An electromagnetic friction disk clutch for use in vehicles is described, which permits a significant saving in energy over known clutches. For this purpose, the clutch according to the invention is embodied in such a way that an electromagnet is loaded with a raised strength of current only to change over between the clutch states of the engaged state and the disengaged state. While the clutch remains in these states up to the next shifting process, the supply of current to the solenoid can be greatly reduced or even switched off.
