Die gattungsbildende WO2004/005748 A1 beschreibt eine Sensoranordnung für einen Schwingungsdämpfer, umfassend einen Sensor, der an einem Basisteil fixiert ist, wobei dieses Basisteil von einem Federelement in Richtung einer Kolbenstange vorgespannt wird, wobei die Feder und das Basisteil fest miteinander verbunden sind. Der Sensor ist in einer Kappe integriert, deren radial elastischer Rand zungenartig in eine Endkappe des Schwingungsdämpfers eingreift.The Generating WO2004 / 005748 A1 describes a sensor arrangement for one vibration dampers, comprising a sensor which is fixed to a base part, wherein this base part biased by a spring element in the direction of a piston rod is, with the spring and the base firmly connected are. The sensor is integrated in a cap whose radially elastic Edge tongue-like engages in an end cap of the vibration damper.
Aufgabe der vorliegenden Erfindung ist es eine Sensorhalterung zu entwickeln, mit der die aus dem Stand der Technik bekannten Fertigungsprobleme behoben sind.task the present invention is to develop a sensor mount, with the known from the prior art manufacturing problems are fixed.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass sich eine Baueinheit, umfassend die Feder und das Basisteil, mit einer die Kolbenstange umgreifenden schellenartige Federzunge an der Kolbenstange abstützt.According to the invention Task solved by that a structural unit, comprising the spring and the base part, with a piston rod engaging around the clamp-like spring tongue supported on the piston rod.
Unabhängig von der konkreten Ausgestaltung der Feder und/oder des Basisteils liegt eine gut handhabbare Baueinheit vor, die unabhängig von dem Schwingungsdämpfer hergestellt werden kann.Independent of the specific configuration of the spring and / or the base part is located a well manageable unit that made independent of the vibration damper can be.
Zur Verhinderung von Fehlmessungen ist die Baueinheit in Axialrichtung der Kolbenstange federnd vorgespannt. Bauraumtoleranzen werden von der Federwirkung kompensiert, so dass keine Schleppbewegung der Kolbenstange auf den Sensor auftreten kann.to Prevention of incorrect measurements is the assembly in the axial direction the piston rod resiliently biased. Installation space tolerances are of compensated for the spring action, so that no drag movement of the Piston rod can occur on the sensor.
Der große Vorteil besteht darin, dass etwaige Fertigungs- und Lagertoleranzen der Kolbenstange oder des Gehäuses ausgeglichen werden, da die Zugfeder die Kolbenstange umklammern und ein in sich geschlossenes System bilden, d. h. dass z. B. eine exzentrische oder schiefstehende Kolbenstange keinen Einfluss auf den Sensor ausübt, da dieser zusammen mit der Baueinheit ebenfalls exzentrisch oder schief steht.Of the size Advantage is that any manufacturing and storage tolerances the piston rod or the housing be compensated because the tension spring clasp the piston rod and form a self-contained system, i. H. that z. Legs eccentric or skewed piston rod does not affect exerting the sensor, because this together with the unit also eccentric or is wrong.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist die Feder Teil einer Aufnahme für das Basisteil. Die Aufnahme kann z. B. wie ein Rahmen ausgeführt sein, in dem das Basisteil gehalten wird. Einzelne Rahmenteile können dann eine Federfunktion übernehmen.In Another advantageous embodiment of the invention is the spring Part of a recording for the base part. The recording can z. B. how to run a frame, in which the base part is held. Individual frame parts can then take over a spring function.
Bei einer Alternativvariante besteht das Basisteil aus einem elastischen Spitzwerkstoff und die Feder ist einteilig mit dem Basisteil ausgeführt. Vor dem Spritzvorgang wird die Feder in eine Spritzform eingelegt und dann von dem Spritzwerkstoff fixiert.at an alternative variant, the base part consists of an elastic Tip material and the spring is made in one piece with the base part. Before the Injection process, the spring is placed in an injection mold and then fixed by the spray material.
Bei Schwingungsdämpfern variiert der Kolbenstangendurchmesser sehr stark in Abhängigkeit des Anwendungsfalls. Damit möglichst viele Kolbenstangendurchmesser mit einem gleichartigen Basisteil kombiniert werden können, weist das Basisteil einen Standardanschluss für den Einsatz von maßlich unterschiedlichen Federn auf.at vibration the piston rod diameter varies greatly depending on Use case. As possible many piston rod diameter with a similar base part can be combined the base part has a standard connection for the use of dimensionally different Springs up.
