Abstract

A rolling member bearing with a rotational speed transducer comprising a pulse generating device 4 which rotates with the rolling member 1 and a sensor 5 which opposes the pulse generator and is separated by an air gap. The sensor head 6 is fixed to an attatchment 9 by a member with an elastically deformable region 10. Opposing mating surfaces 7, on the sensor head and 8 on a stationary part of the bearing are used to link the sensor and pulse generator whilst maintaining a substantially constant air gap between the two.

Description

Die Erfindung betrifft eine Wälzlagerung nach dem Oberbegriff des Anspruchs 1.The invention relates to a rolling 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 sehr genau und mit sehr kleinem Abstand zum Impulsgeberrad oder zu einer Kodierscheibe positioniert werden muß. Diese Justierung und Positionierung erfolgt mit Meßfühlerlehren, Paß- oder Unterlegscheiben und/oder erfordert eine hochgenaue Bearbeitung aller Teile, Flächen und Bohrungen, die für die Geometrie der Sensoranlageflächen nötig sind. Dies gilt auch insbesondere bei geteilten Umgebungskonstruktionen (Gehäuse o. ä.).With many roller bearings, there is a need today with them To provide device for detecting the speed. So it is state of the art Technology, wheel bearings of motor vehicles with speed detection equip to z. B. the speed from the signals received derive and this to control an anti-lock braking system to use. The problem is that even low speeds still to be detected and the sensor very precisely and with very small distance to the pulse encoder wheel or to a coding disk must be positioned. This adjustment and positioning is done with Gauges, shims or washers and / or requires one high-precision machining of all parts, surfaces and bores for the Geometry of the sensor contact surfaces are necessary. this is also valid especially in the case of divided surrounding structures (housing or similar).

Wegen dieser hohen Genauigkeitsanforderung hat man versucht, das Impulsgeberrad und den Sensor im oder am Wälzlager anzuordnen (siehe DE 25 05 802 A1), da Wälzlager hochgenau bearbeitete Teile sind. Auf der anderen Seite werden dadurch aber die Wälzlager teuer. Außerdem muß eine genaue Montage und Justierung zwischen Sensor und Impulsgeberring erfolgen.Because of this high accuracy requirement, attempts have been made to do this Place the pulse generator wheel and the sensor in or on the roller bearing (see DE 25 05 802 A1), since roller bearings are highly precisely machined parts. On the on the other hand, this makes the roller bearings expensive. In addition, must an exact assembly and adjustment between sensor and Encoder ring take place.

Nach der DE 44 00 773 A1 hat man vorgeschlagen, ein zusätzliches, als Schräglager ausgebildetes, von einer Feder vorgespanntes Stützlager vorzusehen, welches den Impulsring und den Sensor trägt und führt. Diese Ausführung ist jedoch ebenfalls aufwendig und teuer. Auch hierbei ist eine sorgfältige Justierung des Sensors zum Impulsring erforderlich. According to DE 44 00 773 A1, it has been proposed to use an additional, as Angular bearing formed by a spring preloaded support bearing to provide, which carries and guides the pulse ring and the sensor. However, this version is also complex and expensive. Here too careful adjustment of the sensor to the pulse ring is required.  

Schließlich ist es aus der EP 04 49 671 A2 noch bekannt, bei einem Lager mit Magnetfeldsensor den Sensor an einem flexiblen Arm eines Sensorträgers anzuordnen, wobei der Sensor in dauerndem Kontakt mit dem drehenden Magnetimpulsring steht. Eine solche Lösung bewirkt nicht nur den Verschleiß des Sensorträgers, sondern erhöht auch die Lagerreibung und die Temperatur.Finally, it is also known from EP 04 49 671 A2 for a bearing with a magnetic field sensor the sensor on a flexible arm Arrange sensor carrier, the sensor in constant contact with the rotating magnetic pulse ring. Such a solution does not work only wear the sensor carrier, but also increases the Bearing friction and the temperature.

Es ist deshalb Aufgabe der Erfindung, eine Wälzlagerung der eingangs genannten Art so weiterzubilden, daß eventuelle Positionsfehler der Umbauteile ausgeglichen und auch Maßänderungen der Umbauteile im Betrieb (Temperaturausdehnung, Ringwandern o. ä.) kompensiert werden können und eine einfache Montage und Justierung ermöglicht wird.It is therefore an object of the invention to provide a rolling bearing at the beginning mentioned type so that any position errors of the Modified parts balanced and dimensional changes of the converted parts in the Operation (temperature expansion, ring hiking or similar) can be compensated and easy assembly and adjustment is made possible.

Die Lösung dieser Aufgabe gelingt mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen. Vorteilhafte Weiterbildungen sind in den Ansprüchen 2-5 angegeben.This problem is solved with the in the characterizing part of the Claim 1 specified features. Advantageous further developments are specified in claims 2-5.

Durch die Erfindung wird erreicht, daß sich der Sensor bei der Montage selbst justiert und sich auch den geometrischen Änderungen der Sensoranlageflächen infolge Temperaturausdehnung, elastischer und plastischer Verformung der Gesamtkonstruktion und selbst einem Verdrehen des Außenrings im Gehäuse (Ringwandern) anpaßt. Eine hochgenaue Bearbeitung der entsprechenden Teile und Flächen entfällt.The invention ensures that the sensor during assembly self adjusted and also the geometric changes of the Sensor contact surfaces due to temperature expansion, elastic and plastic deformation of the overall construction and even one Twists the outer ring in the housing (ring wander) adjusts. A high-precision machining of the corresponding parts and surfaces is eliminated.

Die Paßfläche am Sensorkopf und die entsprechend ausgebildete Gegenpaßfläche bilden gleichsam eine Fangvorrichtung für den Sensor, die ihn während der Montage gezielt in seine richtige Position und den richtigen Abstand gegenüber der Impulsgeberscheibe führt und dort fixiert. Dies vereinfacht den Montagevorgang erheblich.The mating surface on the sensor head and the appropriately trained one Mating surface form, as it were, a safety device for the sensor, which specifically positions it in its correct position and during assembly leads to the correct distance from the encoder disk and there fixed. This considerably simplifies the assembly process.

Dadurch, daß die Gegenpaßfläche in Umfangsrichtung umlaufend ausgebildet ist, ist selbst bei einem Ringwandern oder Verdrehen der Gegenpaßfläche der Sensor in Bezug auf die Impulsgeberscheibe stets positioniert. Durch den elastischen Bereich werden auch Maßänderungen der Umbauteile im Betrieb kompensiert. Die erforderliche Laufgenauigkeit ist bei Wälzlagern bzw. deren Lagersitzstellen sowieso gegeben, weshalb auch eine Anordnung der Gegenpaßfläche in die Dichtscheibe ermöglicht wird.Characterized in that the mating surface circumferentially is formed, even with a ring or twisting Always mating surface of the sensor with respect to the pulse encoder disc positioned. Due to the elastic area there are also dimensional changes of the conversion parts in operation compensated. The required running accuracy is given with rolling bearings or their bearing seat anyway, which is why also allows an arrangement of the mating surface in the sealing washer becomes.

Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. The invention will be explained in more detail using an exemplary embodiment.

Neben dem Innenring 1 ist die Impulsgeberscheibe 4 angeordnet, die z. B. als Zahnrad oder Lochscheibe ausgebildet sein kann oder Markierungen in Form von magnetisierten Bereichen oder Magneten aufweist. Der Sensor 5 ist gegenüber der Impulsgeberscheibe 4 am Sensorkopf 6 angeordnet und weist Paßflächen 7 auf, die mit den im Außenring 2 befindlichen Gegenpaßflächen 8 zusammenwirken. Dazu ist zwischen dem Sensorkopf 6 und der Sensorbefestigung 9 ein elastisch verformbarer Bereich 10 vorgesehen, durch den Fluchtfehler und Maßänderungen ausgeglichen werden können.The rolling bearing according to Fig. 1 consists of a rotating inner ring 1, a stationary outer ring 2, and between the races rolling elements arranged. 3 In addition to the inner ring 1 , the encoder disk 4 is arranged, the z. B. can be designed as a gear or perforated disc or has markings in the form of magnetized areas or magnets. The sensor 5 is arranged opposite the pulse generator disk 4 on the sensor head 6 and has mating surfaces 7 which interact with the mating mating surfaces 8 located in the outer ring 2 . For this purpose, an elastically deformable area 10 is provided between the sensor head 6 and the sensor mounting 9 , by means of which misalignments and dimensional changes can be compensated.

Wie in Fig. 2 dargestellt, kann die Gegenpaßfläche 8 auch in eine Dichtscheibe 11 integriert sein was die Verwendung von Normlagern ermöglicht.As shown in Fig. 2, the mating surface 8 can also be integrated in a sealing washer 11 , which enables the use of standard bearings.

Wie in Fig. 3 dargestellt, kann die Gegenpaßfläche 8 auch von einer Nut des Außenrings 2 gebildet werden, in welcher der Sensorkopf 6 radial geführt ist.As shown in Fig. 3, the mating surface 8 can also be formed by a groove of the outer ring 2 , in which the sensor head 6 is guided radially.

Die Sensorbefestigung 9 ist auf verschiedene Weise z. B. im Gehäuse 12 möglich. Ebenso unterschiedlich kann der elastische Bereich 10 ausgestaltet sein, in dem z. B. ein elastischer Werkstoff (Gummi) verwendet wird oder durch Gestaltung des Sensorträgers ein elastische Verformbarkeit erreicht wird.The sensor attachment 9 is z. B. possible in the housing 12 . The elastic region 10 can also be designed differently, in which, for. B. an elastic material (rubber) is used or an elastic deformability is achieved by designing the sensor carrier.
