Description
Die Erfindung betrifft eine Wälzlagerung nach dem Oberbegriff des Anspruchs 1.The The invention relates to a roller bearing according to the preamble of claim 1.
Bei vielen Wälzlagerungen besteht heute das Bedürfnis, sie mit einer Einrichtung zur Erfassung der Drehzahl zu versehen. So ist es Stand der Technik, Radlager von Kraftfahrzeugen mit einer Drehzahlerfassung auszurüsten, um z. B. aus den erhaltenen Signalen die Geschwindigkeit abzuleiten und diese zur Steuerung eines Antiblockiersystems heranzuziehen. Dabei besteht das Problem, dass auch niedrige Drehzahlen noch erfasst werden sollen und der Sensor mit sehr kleinem Abstand zum Impulsgeberrad oder zu einer Kodierscheibe positioniert werden muss.at many rolling bearings there is a need today to provide them with means for detecting the speed. So it is state of the art, wheel bearings of motor vehicles with a speed detection equip, to z. B. derive the speed from the received signals and to use these for controlling an anti-lock braking system. there there is the problem that even low speeds still recorded to be and the sensor with a very small distance to the pulse wheel or must be positioned to a coding disc.

Dabei ist nachteilig, dass solange der Sensor noch nicht montiert oder wieder demontiert ist, die Impulsgeberscheibe gegen Verschmutzung nicht geschützt ist. Dies ist insbesondere dann problematisch, wenn sogenannte aktive Impulsgeber eingesetzt werden. Unter aktiven Impulsgebern werden solche verstanden, die mit Magneten bestückt sind oder magnetisierte Bereiche aufweisen, wodurch eventuell in der Umgebung befindliche Eisenteilchen (kleine Späne) angezogen werden und sich dort festsetzen. Dadurch werden die Signale verfälscht. Auch hierbei muss die Justierung des Sensors sehr sorgfältig erfolgen.there is disadvantageous that as long as the sensor is not mounted or is dismantled again, the pulser disc against contamination not protected is. This is particularly problematic when so-called active Pulse generator can be used. Under active pulse generators are such understood, which are equipped with magnets or magnetized Have areas, which may be located in the environment Iron particles (small chips) be attracted and settle there. This will be the signals falsified. Again, the adjustment of the sensor must be done very carefully.

Es ist deshalb Aufgabe der Erfindung, eine Wälzlagerung der eingangs genannten Art so weiterzubilden, dass die Impulsgeberscheibe zuverlässig vor Verschmutzung geschützt ist und eine einfache und trotzdem genaue und wiederholbare Justierung des Sensors gegenüber der Impulsgeberscheibe ermöglicht wird.It is therefore an object of the invention, a rolling bearing of the aforementioned Refine the type so that the pulser plate reliably before Pollution protected is a simple yet accurate and repeatable adjustment of the Sensors opposite the pulser allows becomes.
Die Lösung dieser Aufgabe gelingt mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen. Eine vorteilhafte Weiterbildung ist in Anspruch 2 und 3 beschrieben.The solution This object is achieved with the in the characterizing part of the claim 1 specified characteristics. An advantageous development is in Claim 2 and 3 described.
Durch die Ausbildung des Sensorträgers als Blechscheibe welche mit ausgestanzten Haltezungen für den Sensor versehen ist und anvulkanisierte Dichtlippen aufweist, die am Lagerring anliegen, und dadurch, dass der Bereich der Ausstanzung durch eine ebenfalls anvulkanisierte Dichtmembrane geschlossen ist, wird nicht nur die Aufgabe gelöst, sondern es wird zusätzlich eine wirkungsvolle verbesserte Abdichtung des gesamten Lagers erreicht.By the training of the sensor carrier as a sheet metal disc which with punched tabs for the sensor is provided and has vulcanized sealing lips on the bearing ring lie, and in that the area of the punched by a also vulcanized sealing membrane is closed, will not just solved the task but it will be additional achieved an effective improved sealing of the entire camp.
Dabei erfolgt das Anbringen und Justieren des Sensors immer einfach und kostengünstig. Die Abdichtung kann dabei sehr dünn ausgeführt werden, da im Betrieb die Membrane direkt am Sensorkopf elastisch anliegt und von diesem gestützt wird. Außerdem kann die Membrane die Toleranzen der Sensorbefestigung elastisch ausgleichen. Zwischen Membrane und Sensor entsteht dabei kein störender Luftspalt.there the attachment and adjustment of the sensor is always easy and inexpensive. The seal can be very thin accomplished Since, in operation, the membrane directly on the sensor head elastic and supported by it becomes. Furthermore the membrane can elastic the tolerances of the sensor attachment compensate. There is no disturbing air gap between the diaphragm and the sensor.
Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden.The Invention is intended to an embodiment be explained in more detail.
