| 20090290988 | Element which Generates a Magnetic Field - An element which generates a magnetic field for fastening a compressor wheel to a turboshaft of an exhaust-gas turbocharger, has a basic body and a thread. In order to specify an element which generates a magnetic field for fastening a compressor wheel to a turboshaft, which element generates as high a magnetic field strength as possible and nevertheless can absorb without damage the forces and the tightening torques which occur during fastening of the compressor wheel to the turboshaft, the entire basic body includes a magnetic material and a sleeve is arranged in the basic body, which sleeve includes a non-magnetic material and has the thread which can be screwed to a mating thread of the turboshaft. | 11-26-2009 |
| 20090320579 | Method and device for measuring an effective normal force on a disk brake - A method and a device for measuring a normal force affecting a disk brake that is used particularly in motor vehicles. In order to further develop a device for measuring an effective normal force so as to significantly decrease the additional mounting space required in the area of a disk brake and reduce sensitivity to thermal influences, a shearing movement of a part of the disk brake relative to a reference is detected by a sensor such that a test signal-processing logic circuit can draw conclusions about an actually effective normal force based on a sensor test signal. | 12-31-2009 |
| 20100026284 | Element for Generating a Magnetic Field - An element for generating a magnetic field, having an annular frame for receiving an annular magnet which rotates with a turboshaft. The magnet is mounted in the frame such that the frame stabilizes and guides the magnet mechanically. In order to specify an element for generating a magnetic field which reliably fixes and guides the magnet, the magnet is connected to the frame by at least one spot weld. | 02-04-2010 |
| 20100178132 | Magnetized Nut For Fastening a Compressor Wheel of an Exhaust Turbocharger to the Turbo Shaft, and Method for the Production Thereof - A magnetized nut for fastening a compressor wheel of an exhaust turbocharger to a turbo shaft. The nut has a base body made of a non-magnetic material forming a hollow space for accommodating a magnetic material, and a method for the production of the magnetized nut. In order to provide a magnetized nut that is produced in a simple and cost-effective manner and ensures as equal a distribution of mass as possible with regard to the rotational axis of the nut, the magnetic material is introduced into the hollow space using injection molding. | 07-15-2010 |
| 20100209256 | Element which Generates a Magnetic Field - An element which generates a magnetic field for securing a compressor wheel to a turboshaft of an exhaust-gas turbocharger, includes a base body that receives an annular-shaped magnet that rotates with the turboshaft. In order to provide an element which generates a magnetic field for securing a compressor wheel to a turboshaft of an exhaust-gas turbocharger, where the magnet is securely fixed and no change in the distribution of mass in the magnetic field occurs even when the magnet breaks, the magnet is connected in a force-fitting manner to the base body. | 08-19-2010 |
| 20110011154 | METHOD FOR THE ON-BOARD FUNCTIONAL DIAGNOSIS OF A SOOT SENSOR IN A MOTOR VEHICLE AND/OR FOR THE DETECTION OF FURTHER CONSTITUENTS IN THE SOOT - A method for on-vehicle functional diagnosis of a soot sensor and/or for detecting further components in the soot in a motor vehicle having an internal combustion engine, the soot sensor connected electrically to an evaluation circuit. To specify a method for functional diagnosis of a soot sensor and/or for detecting further components in the soot, by which it is possible to detect a faulty soot sensor and/or further components in the soot in an economical manner, the evaluation circuit measures a temperature coefficient of the soot sensor and detects the faultiness of the soot sensor and/or the presence of further components in the soot from the temperature coefficient of the soot sensor. | 01-20-2011 |
| 20110015824 | METHOD FOR THE ON-BOARD FUNCTIONAL DIAGNOSIS OF A SOOT SENSOR IN A MOTOR VEHICLE AND/OR FOR THE DETECTION OF FURTHER CONSTITUENTS IN THE SOOT - A method for the on-board functional diagnosis of a soot sensor and detection of further constituents in the soot in a motor vehicle having an internal combustion engine. The soot sensor is connected electrically to an evaluation circuit in the motor vehicle. A faulty soot sensor and/or further constituents in the soot can be detected in an inexpensive way. The evaluation circuit measures the voltage coefficient of the soot sensor and detects the defectiveness of the soot sensor and/or the presence of further constituents in the soot using the voltage coefficient of the soot sensor. | 01-20-2011 |
| 20110088450 | Method For Evaluating the State of A Soot Sensor In A Motor Vehicle - A method for performing on-board functional diagnostics on a soot sensor of a vehicle and/or for detecting further components in the soot in a motor vehicle having an internal combustion engine. The soot sensor is electrically connected to an evaluation circuit with is permanently installed in the motor vehicle. In order to specify a method for performing functional diagnostics on a soot sensor and/or for detecting further components in the soot, with which method it is possible to detect a faulty soot sensor and/or further components in the soot in a cost-effective way, the evaluation circuit measures the temperature coefficient of the soot sensor and detects the defectiveness of the soot sensor and/or the presence of further components in the soot on the basis of the temperature coefficient of the soot sensor. | 04-21-2011 |
| 20110156727 | Soot Sensor - A soot sensor for the detection of soot particles in an exhaust gas flow, having interdigitally engaged measurement electrodes applied on a substrate. An electrical resistance between the measurement electrodes is a measure of soot load of the exhaust gas flow. The measurement electrodes are divided into two regions, a first region in which no soot particles can be deposited and a second region where soot particles are deposited from the exhaust gas flow. The first region and the second region are exposed simultaneously to the other conditions prevailing in the exhaust gas flow. | 06-30-2011 |
