Definitions
- the invention relates to a circuit board for connecting a deformation sensor, which is arranged on a radial outer side of a roller bearing outer ring to a signal processing circuit and a wheel bearing for a vehicle with the circuit board.
- CONFIRMATION COPY electrical contacting with the deformation sensor and an electrical interconnect electrically connected to the electrical Kunststoffierpad, which is adapted to receive signals from the deformation sensor and forward it to the signal processing circuit.
- the specified method is based on the consideration that the signals which are emitted by the deformation sensors in the abovementioned wheel bearing have only a very low power and thus a low signal-to-noise ratio. Thus, the dimensionable length of an electrical line over which these signals can be transmitted, limited. On the other hand, it is recognized in the context of the specified method, however, that it is often necessary to travel several meters between a sensor and a circuit, particularly in the vehicle sector, which continues to use the signals from the sensor for processing information. The aforementioned signals would be lost in the background noise.
- the printed circuit board is adapted in its shape to the outer ring.
- any electrical circuit elements can be brought close to the deformation sensor, so that its signal can be used effectively and with little interference.
- the deformation sensor can be chosen arbitrarily.
- known surface strain gauges or surface wave filters can be used as the surface sensor.
- Surface wave filters are components of a piezoelectric material. This material is structured to have defined filter / runtime properties. Due to a mechanical deformation, these filter / transit time properties change, which can be detected with an evaluation circuit.
- the cylindrical support plate is used in the specified circuit board as a wiring carrier. It can be made in any way, but should be constructed of an electrically insulating material. Particularly preferably, the cylindrical support plate is an injection-molded body which can be mass-produced particularly economically. As spraying technique, a 1K or 2K spraying technique known per se to the person skilled in the art could be chosen here.
- any electrically insulating material can be used. If, for example, a plastic such as polyphenylene sulfide, called PPS, or a Lyquid crystal polymer, called LCP selected, the cylindrical support plate electrically isolates the printed conductors and other electrical components against each other, and further has an optimal mechanical stability, for example To absorb the vibrations acting on the outer ring and thus to protect the printed conductors and other electrical components from fatigue fractures and other mechanical damage.
- the cylindrical carrier plate thus not only carries the electrical wiring but also serves as a vibration damper. After the above-mentioned injection process, the cylindrical support plate can be partially coated with an electrically conductive surface.
- the surface of the carrier plate can be pretreated at the points to be coated in a conductive manner by means known per se, for example laser structuring, in order to support the following partial coating process.
- contacting surfaces can be reworked on the coated surface of the cylindrical carrier plate in order to ensure reliable electrical contacting, for example with the above-mentioned signal processing elements or the evaluation electronics.
- This aftertreatment may include smoothing and / or surface cleaning of the contact surfaces and / or electroplating processes.
- the surface cleaning can be done by plasma treatments, laser processing, wet baths and / or per se known CO2-Jetting.
- the cylindrical shape of the carrier plate can be configured as desired. The cylindrical shape may or may not close around the circumference of the rolling bearing outer race or rolling bearing inner race.
- the two circumferentially considered ends of the carrier plate can also be held together with holding elements such as bridges or clamps.
- the carrier plate in the circumferential direction would in principle not need to be closed in order to ensure mechanical stability.
- the cylindrical shape should be interpreted in the context of the present invention such that the carrier plate surrounds the roller bearing outer ring in the circumferential direction or runs in the circumferential direction on the inside of the roller bearing inner ring.
- the specified printed circuit board comprises at least a part of the signal processing circuit, which is supported on the carrier plate.
- This part can be, for example, signal conditioning elements with which the signal from the deformation sensor can be prepared for further transmission over a longer distance.
- the contact pad and the printed conductor are located on a radial outer side of the cylindrical printed circuit board Carrier plate arranged. In this way, regardless of whether it is first placed on the outer ring of the rolling bearing, the printed circuit board can be fitted with parts of the signal processing circuit, since the radial outer side of the cylindrical support plate remains accessible after placing it on the outer ring.
- the specified printed circuit board comprises a radial passage opening through the cylindrical carrier plate for guiding an electrical line which electrically connects the deformation sensor with the contacting pad.
- the radial passage opening makes it possible to first form or fix the deformation sensor on the outer ring of the rolling bearing, then push the cylindrical support plate onto the outer ring and finally electrically connect the deformation sensor with a tool, such as a bonding tool, to the electrical conductor on the cylindrical support plate to contact.
- TAB taped automatic bonding
- the specified circuit board comprises a sleeve in which the cylindrical support plate is concentrically receivable.
- the sleeve is used in the particular development as a shield for the cylindrical support plate and formed on their electrical circuit against mechanical and / or electrical environmental influences, such as mechanical dirt and / or electromagnetic interference and can be such as mechanical resistance and / or electromagnetic Compatibility, called EMC, improve the cylindrical support plate.
- the sleeve is particularly preferably made of a conductive material with a high mechanical strength, such as a metal.
- the sleeve can be constructed arbitrarily, such as from a grid or a homogeneous metal wall and / or axially open or closed axially.
- a filling material is accommodated radially between the carrier plate and the sleeve, in particular in the region of the electrical contacting points on the cylindrical carrier plate and the deformation sensor.
- the filling material encloses the electrical components, such as the electrical connections between the deformation sensor and the electrical circuit on the cylindrical support plate, protects them from environmental influences and serves as mechanical damping against vibrations. In addition, it can support the sleeve on the support plate.
- the filler material may be called a silicone gel, called SilGel, which can adapt to the shape of the radial gap between the cylindrical support plate and the sleeve, so that it can be introduced at any moment in the production of the specified circuit board in this radial gap
- the specified printed circuit board comprises at least two support elements on the cylindrical support plate, which are directed radially inwardly on a radial inner side of the cylindrical support plate.
- the support elements stabilize the mechanical support of the cylindrical support plate on the outer ring, but keep the cylindrical support plate radially spaced therefrom, and ensure that the deformation sensor is not touched by the cylindrical support plate and thus damaged.
- the specified printed circuit board comprises a third support element on the cylindrical support plate, which is directed radially inwardly on a radial inner side of the cylindrical support plate and radially shorter than the other two support elements.
- the deformation sensor can be arranged axially between this third support element and one of the two other support elements, wherein the above-mentioned radial passage opening can then be correspondingly formed at this point.
- the radially shorter of the two support members may be mounted in front of the radially longer of the two support elements.
- the radially shorter support member can be pushed in the radial direction over the deformation sensor, without damaging it.
- the radially shorter support element radially supports the cylindrical support plate, for example when the deformation sensor is electrically connected to the electrical circuit on the cylindrical support plate or under other mechanical loads, and further reduces mechanical stresses on it.
- a wheel bearing for a vehicle comprises an inner ring rotatably supported by rolling elements in an outer ring, a deformation sensor disposed on a radially outer side of the outer ring, and one of the indicated printed circuit boards for electrically connecting the deformation sensor to the signal processing circuit - tion.

- the outer ring comprises a radially outwardly projecting flange for attachment to a strut of a vehicle, on which the cylindrical support plate rests axially.
- the deformation sensor is mounted non-rotatably to the vehicle, and so deformations of the outer ring can be determined fixed to the vehicle.
- the wheel bearing itself can be an arbitrary wheel bearing from the second generation. Background to this can be found in the textbook Bernd H contributing, "Fahrtechnikhandbuch", 3rd edition, Vieweg + Teubner Verlag, 201 1, ISBN 978-3-8348-0821 -9.
