摘要： Device (1) for determining a quantity by means of a capacitive measurement, comprising: - a first part (2) comprising at least two first electrodes (40,41-43); and - a second part (3) movable relative to the first part and comprising at least one second electrode (50,51), wherein: - the at least two first electrodes are coupled capacitively to the at least one second electrode; and - the device also comprises at least two electrical conductors which are connected to the at least two first electrodes, characterized in that the at least one second electrode is electrically floating. Each electrode is fixedly connected to the remaining portion of the part concerned. Because only the first electrodes need be connected to electrical conductors, and the electrically floating, moving relative to the first electrodes, second electrode(s) do not, the electrical conductors will, in any case at least at the location of the connections to the electrodes, not move relative to each other during use of the device, whereby the chance of breakage as a result of this relative movement is minimal. Following the measurement of at least one capacitance value by applying an electric voltage between the at least two first electrodes by means of the at least two electrical conductors, the relative position of the first and the second part can be derived therefrom or, when the first part and the second part are coupled in resiliently mechanical manner, the magnitude of the mutual force or mechanical load. With a chosen rotation symmetry, the measured value(s) will be independent of deviations in the direction and/or the point of engagement of the force or of irregularities in the distribution of the mechanical load. By combining a number of independent measurements and because of built-in checking options, a force or mechanical load can be determined with great accuracy and very great reliability. The device can be embodied here compactly and with a very low overall height. Also method for determining a quantity by means of a capacitive measurement by means of a device according to the invention.

摘要： The invention provides a wheel suspension characterized in that the wheel suspension comprises a sensor suitable for measuring a mechanical quantity and also a method for determining a mechanical quantity in a wheel suspension, characterized in that a sensor suitable for measuring a mechanical quantity is applied. The sensor is here preferably a capacitive sensor. Such a sensor is robust and is found to be highly satisfactory in practice. The mechanical quantity to be determined can be a relative mechanical load between two components of the wheel suspension, for instance a relative force, stress or moment of force. The sensor is connected mechanically here to the two components such that the relative mechanical load can be determined by measuring the mechanical quantity by means of the sensor. The sensor is preferably connected mechanically to the two components here such that the relative mechanical load is transmitted wholly via the sensor. The relative mechanical load to be determined can thus be measured directly by means of the sensor, whereby the reliability and the accuracy of the determined value are high. The mechanical quantity to be determined can also be a mechanical deformation of a component of the wheel suspension, for instance a bending or torsion. The sensor is connected mechanically to the component here such that the mechanical deformation can be determined by measuring the mechanical quantity by means of the sensor. The components can for instance be a part of a chassis or superstructure, a wheel axle, a spring, a support arm or connecting element, or a shock absorber. The invention also provides a vehicle comprising a device according to the invention.
