Description
Die
Erfindung bezieht sich auf ein Verfahren zur kontinuierlichen Bestimmung
der Zugkraft F in einem Seil einer Feststellbremse. Verfahren zur
kontinuierlichen Bestimmung der Zugkraft in Seilen von Feststellbremsen
sind bekannt. In der
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur kontinuierlichen Bestimmung der Zugkraft in einem Seil einer Feststellbremse zu schaffen, bei dem das Seil nicht unterbrochen werden muss. Auf die Anordnung von Kraftmesseinrichtungen direkt im Seil soll dabei vollständig verzichtet werden.Of the The invention is therefore based on the object, a method for continuous Determining the traction in a rope of a parking brake, where the rope does not have to be interrupted. On the arrangement Force measuring devices directly in the rope should be completely dispensed with become.
Die der Erfindung zugrunde liegende Aufgabe wird durch ein Verfahren zur kontinuierlichen Bestimmung der Zugkraft F in einem Seil einer Feststellbremse gelöst, bei dem die Zugkraft F über eine an einem Seilende angeordnete Seilendverbindung in einen bezüglich seiner Längsachse elastischen Sensorträger eingebracht wird, der mit einem Längensensor verbunden ist, dessen Signalspannung von der Längenänderung und somit von der Größe der Zugkraft F abhängig ist, und die Zugkraft F dann aus der jeweiligen Signalspannung ermittelt wird. Die im Seil vorhandene Zugkraft F wird somit über die angeordnete Seilendverbindung dem Längensensor zugeleitet. Dabei ist es vorgesehen, dass das Einbringen der Zugkraft F in das Seil von dem elastischen Sensorträger ausgehend über die Seilendverbindung in das Seil erfolgt. Dies kann beispielsweise dadurch geschehen, dass der elastische Sensorträger an seinem, der Seilendverbindung abgewandten Ende mit einer Antriebsspindel verbunden ist, die dann direkt mit dem Antrieb der Feststellbremse in Verbindung steht. Die Seilendverbindung besteht in der Regel ebenfalls aus Stahl und ist fest mit dem Seilende verbunden. Als Längensensor eignet sich beispielsweise ein herkömmlicher Längensensor, der mit einer Versorgungsspannung beaufschlagt wird. In ihn wird somit die durch die Zugkraft F hervorgerufene Längenänderung des elastischen Sensorträgers verarbeitet. Er besteht in der Regel aus einem keramischen Werkstoff als Grundkörper. In der Regel beträgt die durch die Zugkraft F hervorgerufene Längenänderung zwischen 30 und 70 μm. Die Ermittlung der tatsächlichen Zugkraft F wird aus der jeweiligen Signalspannung ermittelt, wobei unter der Signalspannung dann diejenige Spannung zu verstehen ist, die der Längensensor je nach der Größe der Längenänderung abgibt. Es besteht somit ein funktioneller Zusammenhang zwischen der Signalspannung und der Zugkraft F. Die Ermittlung der Zugkraft F erfolgt dann aus der jeweiligen Signalspannung mithilfe einer Sende-/Empfangseinheit, die als Rechnereinheit wirkt. Der elastische Sensorträger besteht in der Regel aus Stahl, kann jedoch auch aus speziellen Kunststoffen gefertigt sein. Sofern der elastische Sensorträger aus Stahl besteht, weist er konstruktiv einen elastischen Bereich auf, der die entsprechende Längenänderung möglich macht. Es hat sich in überraschender Weise gezeigt, dass eine kontinuierliche Bestimmung der Zugkraft F auf diese Weise besonders vorteilhaft durchgeführt werden kann, wobei sichergestellt ist, dass keine Kraftmesseinrichtungen direkt im Seil angeordnet werden müssen. Auf Unterbrechungen des Seiles kann ferner in vorteilhafter Weise verzichtet werden.The The object underlying the invention is achieved by a method for continuously determining the tensile force F in a rope of a Parking brake released, where the tensile force F over an arranged at a cable end Seilendverbindung in a respect to his longitudinal axis elastic sensor carrier is introduced, which is connected to a length sensor whose Signal voltage from the change in length and thus the size of the traction F dependent is, and the tensile force F then determined from the respective signal voltage becomes. The existing in the rope traction F is thus on the arranged Seilendverbindung the length sensor supplied. there It is envisaged that the introduction of the tensile force F in the rope from the elastic sensor carrier starting over the rope end connection is made in the rope. This can be, for example be done by the elastic sensor carrier at his, the Seilendverbindung opposite end is connected to a drive spindle, which then directly in contact with the drive of the parking brake. The rope end connection is usually also made of steel and is firmly connected to the rope end. As a length sensor is suitable, for example a conventional one Length sensor, which is supplied with a supply voltage. In it becomes thus processed by the tensile force F caused change in length of the elastic sensor carrier. It usually consists of a ceramic material as a basic body. In the rule is caused by the tensile force F length change between 30 and 70 microns. The investigation the actual Traction force F is determined from the respective signal voltage, wherein under the signal voltage then that voltage is to be understood, the length sensor depending on the size of the change in length emits. There is thus a functional connection between the signal tension and the tensile force F. The determination of the tensile force F then takes place from the respective signal voltage by means of a transmitting / receiving unit, which acts as a computer unit. The elastic sensor carrier exists usually made of steel, but can also be made of special plastics be made. If the elastic sensor carrier consists of steel, points He constructively an elastic range, the corresponding change in length possible power. It has become more surprising Way shown that a continuous determination of the traction F can be carried out particularly advantageous in this way, being ensured is that no force measuring devices arranged directly in the rope Need to become. On interruptions of the rope can also advantageously be waived.
Gemäß einer bevorzugten Ausgestaltung der Erfindung wird die Zugkraft F in einen in seinem Mittelteil einen bezüglich seiner Längsachse elastischen Bereich aufweisenden elastischen Sensorträger eingebracht. Dieser elastische Bereich kann beispielsweise nahezu V-förmig gestaltet sein. Es ist jedoch auch möglich, den elastischen Bereich in Form einer Spiralfeder auszubilden. Dadurch wird die Stabilität des Sensorträgers in vorteilhafter Weise erhöht und der Einsatz von preiswerten Werkstoffen begünstigt.According to one preferred embodiment of the invention, the tensile force F in a in his middle part one concerning his longitudinal axis elastic region having elastic sensor carrier introduced. This elastic region can be designed, for example, almost V-shaped be. However, it is also possible form the elastic region in the form of a spiral spring. Thereby will the stability of the sensor carrier increased in an advantageous manner and the use of inexpensive materials favors.
Eine weitere bevorzugte Ausgestaltung der Erfindung besteht darin, dass die Zugkraft F in einen elastischen Sensorträger eingebracht wird, der mit dem Längensensor ein Einzelteil bildet. Dabei ist vorteilhaft, dass die elektrisch wirksamen Einheiten des Drucksensors direkt auf die Oberfläche des elastischen Sensorträgers aufgebracht werden können, was in vorteilhafter Weise einen zusätzlichen Bauraum einspart.A Another preferred embodiment of the invention is that the tensile force F is introduced into an elastic sensor carrier, which is connected to the length sensor an item forms. It is advantageous that the electric effective units of the pressure sensor directly on the surface of the elastic sensor carrier can be applied, what advantageously an additional Saves space.
Nach einer weiteren bevorzugten Ausgestaltung der Erfindung erfolgt die Übertragung des Signals und der Versorgungsspannung zwischen dem Längensensor und einer Sende-/Empfangseinheit drahtlos. Dies wird in besonders vorteilhafter Weise durch die Anordnung von Spulen ermöglicht. Dadurch kann weiterer Bauraum in vorteilhafter Weise eingespart werden.To In another preferred embodiment of the invention, the transmission takes place the signal and the supply voltage between the length sensor and a transmitting / receiving unit wirelessly. This is going to be special advantageously by the arrangement of coils allows. As a result, further space can be saved in an advantageous manner become.
