Abstract

The pulse transducer consists of a ring (5) with uniformly spaced apertures in the central region and bounded by struts. The ring is pressed onto the outer surface (3) of a rotating counter piece. The struts (6) are angled away from the sensor (9) in the region of a radially offset lateral edge (8). The pulse ring rests on the outer surface of the attachment parts, which can also be angled, with all of its inner surface sections. The angled region (6") of the pulse ring extends over about one third of its total width. ADVANTAGE - Exact measurement of revolution rate of motor vehicle wheel using simple design.

Description

Die Erfindung bezieht sich auf einen Impulsgeber nach dem Oberbegriff des Anspruchs 1.The invention relates to a pulse generator the preamble of claim 1.

Ein Impulsgeber der angegebenen Art ist aus der US-PS 47 95 278 ersichtlich. Der hier gezeigte Ring ist re­ lativ einfach herstellbar, denn die Stege können durch Ausstanzen der Taschen erzeugt werden. Da er auf sei­ ner ganzen Breite auf der Mantelfläche des Gegenteils sitzt erfolgt eine genaue Befestigung. Nachteilig ist aber der sensornahe Seitenrand des Impulsrings, denn der Sensor wird durch dessen Masse gestört. Der Sensor kann aber aus konstruktiven Gründen nicht kleiner und der Impulsring nicht breiter gemacht werden. Weiterhin würde ein Weglassen des einen Seitenrands den Wegfall einer guten Halterung des Stege bewirken und zu Un­ genauigkeiten bei der Drehzahlmessung führen. Nun ist es zwar au der DE-OS 37 02 474 bekannt, die Seiten­ ränder so abzubiegen, daß sich im Querschnitt eine etwa S-förmige Gestalt ergibt. Damit wurden zwar die Seitenränder in meßtechnisch günstiger Weise verla­ gert, sie liegen aber nicht mehr an den Gegenteilen an und können daher eine ungenaue Positionierung der Siege bewirken.A pulse generator of the specified type is from the US PS 47 95 278 can be seen. The ring shown here is right relatively easy to manufacture, because the webs can through Punching out the pockets are generated. Since he was up full width on the outer surface of the opposite there is an exact attachment. The disadvantage is but the sensor edge of the impulse ring, because the sensor is disturbed by its mass. The sensor but can not be smaller and for structural reasons the impulse ring cannot be made wider. Farther omitting one side edge would eliminate it cause a good retention of the webs and to Un lead accuracy in the speed measurement. Now is it is known from DE-OS 37 02 474, the pages bend edges so that a cross-section gives approximately S-shaped shape. With that, the Leave margins in a technically favorable manner but they are no longer due to the opposite and can therefore imprecise positioning of the Make victories.

Es ist daher Aufgabe der Erfindung einem Impulsgeber nach dem Oberbegriff des Anspruchs 1 so weiter zu ver­ bessern, daß er bei einfachstem Aufbau eine exakte Messung der Drehzahl möglich macht. It is therefore an object of the invention to provide a pulse generator ver to continue according to the preamble of claim 1 improve that it is an exact with the simplest construction Speed measurement makes possible.  

Die Lösung dieser Aufgabe ist im kennzeichnenden Teil des Anspruchs 1 angegeben. Der Anspruch 2 enthält eine bevorzugte Ausführung.The solution to this problem is in the characterizing part of claim 1 specified. Claim 2 contains one preferred version.

Der Impulsring nach Anspruch 1 ist leicht herstellbar, denn er besteht aus einem einfachen, gekröpften Ring mit eingestanzten Unterbrechungen, die die für die Drehzahlermittlung nötigen Stege ergeben. Wenn er auf einer in gleicher Weise mit einem gekröpften Abschnitt versehenen Mantelfläche eines Gegenteils z. B. dem Au­ ßenring eines Wälzlagers aufgepreßt wird, werden even­ tuelle Ungenauigkeiten korrigiert. Beide Seitenränder liegen dabei voll an der Gegenfläche an. Nachträgliche Beschädigungen oder Verbiegungen werden dadurch redu­ ziert.The pulse ring according to claim 1 is easy to manufacture, because it consists of a simple, cranked ring with interruptions stamped in for the Speed determination result in necessary webs. When he's on one in the same way with a cranked section provided lateral surface of an opposite z. B. the Au outer ring of a rolling bearing is pressed on, even corrected inaccuracies. Both sides lie fully against the counter surface. Subsequent Damage or bending are reduced graces.

Fertigungstechnisch günstig ist eine Ausführung bei der der gekröpfte Abschnitt etwa ein Drittel der Breite des Impulsrings beträgt. Dies ist auch optimal für die Meßgenauigkeit, denn der störende Seitenrand ist dann ausreichend weit vom Sensor entfernt.An execution at is technically favorable the the cranked section about a third of the Width of the pulse ring. This is also optimal for measuring accuracy, because the annoying side edge is then sufficiently far from the sensor.

Die Erfindung wird an Hand einer Figur näher erläu­ tert. Diese zeigt einen Teilquerschnitt durch ein Wälzlager mit dem neuen Impulsring.The invention is explained in more detail with reference to a figure tert. This shows a partial cross section through Rolling bearings with the new impulse ring.

Gemäß der Figur ist der Außenring 1 eines Schrägkugel­ lagers 2 an seiner Mantelfläche 3 mit einem reduzier­ ten Absatz 4 versehen. Auf der Mantelfläche 3 ist der Impulsring 5 aufgepreßt. Er besteht aus den Stegen 6 und den beiden Seitenrändern 7 und 8. Der rechte Sei­ tenrand 7 sitzt dabei mit den anschließenden Stegab­ schnitten 6′ fest auf der Mantelfläche 3. Dem Ab­ schnitt 6′ steht der Sensor 9 gegenüber. Dabei wird die Drehzahlmessung nicht gestört, denn der sensornahe Seitenrand 8 ist, da er auf dem reduzierten-Absatz 4 sitzt, ausreichend weit aus dem Resonanzbereich ent­ fernt. Trotzdem ergibt sich über den gekröpften Ver­ bindungsbereich 6′′ der Stege 6 eine stabile Ausführung des Impulsrings 5.According to the figure, the outer ring 1 of an angular ball bearing 2 is provided on its lateral surface 3 with a reduced paragraph 4 . The impulse ring 5 is pressed onto the lateral surface 3 . It consists of the webs 6 and the two side edges 7 and 8 . The right Be tenrand 7 sits with the subsequent web cut 6 'firmly on the lateral surface 3rd From the section 6 ', the sensor 9 is opposite. The speed measurement is not disturbed, because the sensor-near side edge 8 , since it sits on the reduced section 4 , is sufficiently far from the resonance range. Nevertheless, there is a cranked Ver connection area 6 '' of the webs 6, a stable design of the impulse ring 5th
