| 20110182757 | APPARATUS FOR A PUMP, AND A WATER PUMP - An apparatus is proposed for a pump, in particular a water pump of a motor vehicle having a rotating pump wheel which can be driven, and having a switchable clutch arrangement for switchable connection of the pump wheel to a drive side. According to the invention, the pump wheel is mounted such that it can rotate on a rotatable driveshaft. | 07-28-2011 |
| 20110005887 | ELECTROMAGNETIC FRICTION CLUTCH - The invention discloses an electromagnetic friction clutch for driving a fan impeller in the engine compartment of a vehicle, for example, the clutch comprising a disk rotor consisting of a plane flat part, a further clutch element which is supported so that it is freely rotatable and which can be driven by the rotor through controllable friction contact, and elements for transmitting a rotational movement according to the principle of an eddy current drive. An eddy current ring is fitted to the outer edge area of the disk rotor, thereby allowing a compact and cost-effectively simple construction of the clutch. | 01-13-2011 |
| 20110005883 | ELECTROMAGNETIC FRICTION CLUTCH - An electromagnetic friction clutch having an eddy current drive is disclosed, said clutch being used for controllably driving auxiliary units such as a coolant pump, for example, in vehicles. An advantageous, rotationally fixed connection of magnetic elements of the eddy current drive to a rotor allows a plurality of embodiments of the invention, with various design simplifications. | 01-13-2011 |
| 20100263981 | FLIP-FLOP CLUTCH - 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. | 10-21-2010 |
| 20100122673 | DRIVE UNIT FOR A FAN AND ARRANGEMENT WITH A DRIVE UNIT - The invention relates to a drive unit for a fan of an internal combustion engine of a vehicle, having a friction clutch which can be shifted in order to drive the fan via the internal combustion engine. An electric motor is also provided for driving the fan, and a torque-transmission path is formed between the friction clutch and the fan by means of a rotatably mounted part of the electric motor. The invention also relates to an arrangement for driving a fan via an internal combustion engine with a drive unit that includes an electric motor and a friction clutch. | 05-20-2010 |
| 20100065398 | ELECTROMAGNETICALLY OPERATED CLUTCH AND METHOD OF OPERATING AN ELECTROMAGNETICALLY OPERATED CLUTCH - An electromagnetically operated clutch, in particular a friction clutch, for switching on and off units, such as a water pump, in a vehicle, having a predefined electrical system voltage, the clutch including an electromagnet with at least one coil, a rotor, an armature plate, which is attracted to the rotor by the forces of the electromagnet in order to engage the clutch, and control means. The control means, which, in respect of a continuous operating state, are designed for an operating voltage level, which is less than the available electrical system voltage of the vehicle, the control means being suited to switching the electromagnet with a voltage level for engagement of the friction clutch that is greater than operating voltage level and, by timing the supply voltage, to reducing it to the design operating voltage level for an operating phase when the clutch is continuously engaged. | 03-18-2010 |
| 20100065396 | FRICTION COUPLING - The invention proposes a friction coupling, in particular for use in motor vehicles, e.g. for controlling an air compressor, in which coupling at least two friction surfaces can be brought into frictional connection. According to the invention, two conical friction surface pairs are provided. | 03-18-2010 |
