20090321213 | FRICTION CLUTCH FOR TRANSMITTING TORQUE - A friction clutch for transmitting torque from a rotor, which can be driven about an axis S, to an element which is to be driven, including a friction disk clutch having an electromagnet arrangement which has a coil former and magnetically conductive means which comprise a web section lying radially on the outside with respect to the axis S and a web section lying radially on the inside and oriented axially, and permanently magnetic means via which an axially movable friction section of the friction disk clutch can be magnetically connected to the rotor, wherein, in the electrically switched on state of the electromagnetic arrangement, the bearing of the friction section against the rotor can be eliminated by attenuating the magnetic attraction effect of the permanently magnetic means. | 12-31-2009 |
20090242350 | ELECTROMAGNETICALLY ACTUABLE CLUTCH AND WATER PUMP HAVING AN ELECTROMAGNETICALLY ACTUABLE CLUTCH - 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. | 10-01-2009 |
20090214359 | LIQUID PUMP FOR AN INTERNAL COMBUSTION ENGINE AND DEVICE FOR HEATING LIQUID - A liquid pump for an internal combustion engine having a housing in which a pump rotational shaft is accommodated, in particular a water pump of a heat exchanger circuit of a vehicle, and an eddy current arrangement is provided at least partially inside the housing of the liquid pump. The invention furthermore relates to a device for heating a liquid. | 08-27-2009 |
20090160589 | DEVICE WITH AN ELECTROMAGNET, CLUTCH, AND METHOD FOR PRODUCING AN ELECTROMAGNET - The invention relates to an apparatus having an electromagnet, comprising a coil and magnetic-field guide means, which at least partially surround the coil. According to the invention, the coil is provided with a sprayed or cast casing, wherein the magnetic-field guide means are formed from a material which comprises ferromagnetic metal particles and plastic material. The invention also relates to a clutch having an apparatus such as this, and to a method for production of an electromagnet. | 06-25-2009 |
