Die
Erfindung geht aus von einer Vorrichtung zur Messung des Drehmomentes
an einer Welle, insbesondere zur Messung des Lenkmomentes einer Zahnstangen-Hilfskraftlenkung
eines Kraftfahrzeuges, mit einer in die Welle integrierten magnetischen Gebereinheit,
deren Kodierung durch Torsion veränderbar ist. Eine derartige
Vorrichtung ist beispielsweise aus der Veröffentlichung der
Offenbarung der ErfindungDisclosure of the invention
Das Messergebnis kann gegenüber bekannten Vorrichtungen deutlich verbessert werden, wenn erfindungsgemäß ein die magnetische Kodierung tragendes Torsionselement mit gegenüber der Welle reduzierter Steifigkeit in den Wellenzug integriert wird, wobei zweckmäßigerweise die maximale Verdrehung begrenzt wird, um bleibende Verformungen des Torsionselementes zu verhindern. Dies geschieht in grundsätzlich bekannter Weise durch den Einbau eines mechanischen Überlastschutzes zwischen den Enden zweier Teilwellen im Wirkungsbereich des Torsionselementes.The Measurement result can be opposite Known devices are significantly improved if according to the invention a magnetic coding torsional element with respect to the Shaft of reduced stiffness is integrated into the wave train, wherein expediently the maximum twist is limited to permanent deformations to prevent the torsion element. This happens in basically known Way by installing a mechanical overload protection between the ends two partial waves in the range of action of the torsion element.
Die erfindungsgemäße Vorrichtung mit den Merkmalen des unabhängigen Anspruchs hat den Vorteil, dass die grundsätzlich bekannte magnetostriktive Messung des Drehmomentes an einer sich drehenden oder stillstehenden Welle für neue Anwendungen durch die Erzeugung eines ausreichend großen, gut erfassbaren Messsignals nutzbar gemacht werden kann. Hierbei ist es besonders vorteilhaft, wenn das Torsionselement im Wesentlichen hülsenförmig ausgebildet ist und an den Enden der Teilwellen angreift, an denen innerhalb des Torsionselementes auch die Überlastkupplung ausgebildet ist. Diese ist vorzugsweise als Klauenkupplung gestaltet, wobei die Klauen ohne Vergrößerung des Wellendurchmessers direkt an den Enden der Eingangswelle und der Ausgangswelle ausgebildet werden können. Hierbei sind die Wellenenden durch einen beidseitig eingreifenden, axial ausgerichteten Lagerstift zentriert und gehalten, sodass auftretende Biegemomente ebenfalls ohne Vergrößerung des Wellendurchmessers abgefangen werden können.The inventive device with the characteristics of the independent Claim has the advantage that the basically known magnetostrictive Measuring the torque on a rotating or stationary Wave for new applications by generating a big enough, good detectable measurement signal can be harnessed. Here is it is particularly advantageous if the torsion element substantially sleeve-shaped is and at the ends of the partial waves attacks, in which the torsion element and the overload clutch is trained. This is preferably designed as a dog clutch, wherein the claws without enlargement of the Shaft diameter directly at the ends of the input shaft and the Output shaft can be formed. Here are the shaft ends centered by a bilaterally engaging, axially aligned bearing pin and held so that bending moments occurring also without increasing the Shaft diameter can be intercepted.
Die Magnetisierung des Torsionselementes und seine Verbindungen mit den Wellenenden sind vorzugsweise symmetrisch zu der Anordnung der Sensoreinheit ausgebildet, wodurch das Messergebnis weiter verbessert wird, da Messwertveränderungen so optimal erfasst werden können.The Magnetization of the torsion element and its compounds with The shaft ends are preferably symmetrical to the arrangement of the sensor unit formed, whereby the measurement result is further improved because Reading changes can be optimally captured.
