Abstract
Eine Radialkolbenmaschine weist eine in ihrer Exzentrizität verstellbare Kurbelwelle (1) auf, welche ein verschiebbares Bauteil (2) aufweist, in welchem eine Geberkontur (3) angeordnet ist, welche mit einem Sensor (5) zusammenwirkt, so dass die Exzentrizität der Kurbelwelle auf einfache Weise auch bei stehender Radialkolbenmaschine ermittelbar ist.A radial piston engine has an eccentricity adjustable crankshaft (1), which has a displaceable component (2) in which a donor contour (3) is arranged, which cooperates with a sensor (5), so that the eccentricity of the crankshaft to simple Way even with stationary radial piston machine can be determined.
Description
Die Erfindung betrifft eine Radialkolbenmaschine nach der im Oberbegriff von Anspruch 1 näher definierten Art. The invention relates to a radial piston machine according to the closer defined in the preamble of
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Radialkolbenmaschine mit einer in ihrer Exzentrizität verstellbaren Kurbelwelle zu schaffen, bei welcher sich die Exzentrizität auch bei stehender Radialkolbenmaschine auf einfache Weise sensieren lässt. The present invention has for its object to provide a radial piston machine with an adjustable in its eccentricity crankshaft, in which the eccentricity can be sensed easily even when the radial piston engine.
Die Aufgabe wird mit einer auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden gattungsgemäßen Radialkolbenmaschine gelöst. The problem is solved with a generic features of the characterizing features of the main claim radial piston engine.
Erfindungsgemäß weist die Radialkolbenmaschine eine in ihrer Exzentrizität verstellbare Kurbelwelle auf, wobei die Exzentrizität durch Verschieben eines Bauteils innerhalb der Kurbelwelle erreicht wird. According to the invention, the radial piston engine has an adjustable in its eccentricity crankshaft, wherein the eccentricity is achieved by moving a component within the crankshaft.
Die Position dieses verschiebbaren Bauteils wird durch einen Sensor unmittelbar sensiert. Dabei kann der Sensor direkt mit dem verschiebbaren Bauteil zusammenwirken. Es besteht jedoch auch die Möglichkeit, dass der Sensor mit einem weiteren Bauteil zusammenwirkt, welches mit dem verschiebbaren Bauteil in Verbindung steht. The position of this displaceable component is directly sensed by a sensor. The sensor can interact directly with the displaceable component. However, there is also the possibility that the sensor cooperates with another component which is in communication with the displaceable component.
In einer weiteren Ausgestaltungsform der Erfindung ist der Sensor als berührungsloser Sensor ausgebildet. Der Sensor gibt je nach Position des verschiebbaren Bauteils ein elektrisches Signal aus, welches beispielsweise eine analoge Spannung oder ein Pulsbreitenmodulationssignal, ein sogenanntes PWM ist, welches sich in Abhängigkeit der Position des verschiebbaren Bauteils verändert. Hierfür weist das verschiebbare Bauteil oder das weitere Bauteil eine Geberkontur auf, welche durch den Sensor sensiert werden kann. Die Geberkontur kann so ausgeformt sein, dass das ausgegebene Signal linearisiert ist. In a further embodiment of the invention, the sensor is designed as a contactless sensor. Depending on the position of the displaceable component, the sensor emits an electrical signal which, for example, is an analog voltage or a pulse width modulation signal, a so-called PWM, which changes as a function of the position of the displaceable component. For this purpose, the displaceable component or the further component has an encoder contour, which can be sensed by the sensor. The encoder contour can be formed so that the output signal is linearized.
Indem das verschiebbare Bauteil oder das mit dem verschiebbaren Bauteil in Wirkverbindung stehende weitere Bauteil direkt sensiert wird, kann die Exzentrizität der verstellbaren Kurbelwelle auch bei stehender Radialkolbenmaschine sensiert werden und somit das Hubvolumen der Radialkolbenmaschine direkt berechnet werden. Indem die Signalübertragung des Sensors drahtlos erfolgt, kann der Sensor direkt benachbart zur Kurbelwelle und zum verschiebbaren Bauteil innerhalb der Radialkolbenmaschine angeordnet sein. By directly sensing the displaceable component or the further component operatively connected to the displaceable component, the eccentricity of the adjustable crankshaft can be sensed even when the radial piston engine is stationary, and thus the stroke volume of the radial piston engine can be calculated directly. By the signal transmission of the sensor is wireless, the sensor can be arranged directly adjacent to the crankshaft and the displaceable component within the radial piston machine.
