Abstract
Description
Die Erfindung betrifft eine Meßvorrichtung für einen Fensterheber gemäß dem Oberbegriff von Anspruch 1.The The invention relates to a measuring device for one Windows according to the preamble of claim 1.
Elektrisch angetriebene Fensterheber in Kraftfahrzeugen müssen mit einer bestimmten Kraft in den am Türrahmen bzw. Karosserie angebrachten Dichtungsgummi eingefahren werden. Nur so ist ein dichtes schließen der Fensterscheibe gewährleistet. Demzufolge sind während der Entwicklung und auch während der Montage des Fensterhebers nebst der Scheibe in der Tür die vom Fensterheberantrieb auf die Scheibe ausgeübten Kräfte zu messen und mit vorgegebenen Werten zu vergleichen. Hier ist insbesondere die Überschußkraft von Bedeutung, also die Kraft, welche die Scheibe bei angesteuertem Fensterheberantrieb zum Stillstand bringt.electrical powered windows in motor vehicles must be with a certain force in on the door frame or body-mounted sealing rubber retracted. Only then is a dense close the window ensures. As a result, are during the development and also during the assembly of the window regulator together with the disc in the door of the Power window drive to measure forces exerted on the disc and given with Compare values. Here is in particular the excess force of Meaning, meaning the force, which the disk drives Stops window regulator drive to a standstill.
Ein bekanntes Messprinzip hierzu besteht aus einer Federwage, welche mittels einem Seil oder einer Kette zwischen bspw. der Türunterkante und der Scheibenoberkante einzuspannen ist. Wird nun der Fensterheberantrieb zum Bewegen der Scheibe nach oben angeschaltet, so ist, wenn die Scheibe zum Stillstand gekommen ist, die entsprechende Kraft auf der Federwage ablesbar. Nachteilig hierbei ist aber die umständliche Handhabung der Federwage nebst Seil und der entsprechenden Haken zur Befestigung. Auch sind Beschädigungen der Tür und/oder der Scheibe nicht auszuschleißen.One Known measuring principle for this consists of a spring balance, which by means of a rope or a chain between, for example, the bottom edge of the door and the disc top is clamped. Will now the window lift drive turned up to move the disc, so when the Disc has come to a standstill, the corresponding force on the spring carriage readable. The disadvantage here, however, is the complicated Handling the spring carriage together with the rope and the corresponding hook for fixing. Also are damages the door and / or not to wear out the disc.
Aufgabe der vorliegenden Erfindung ist es daher, eine Meßvorrichtung gemäß dem Oberbegriff von Anspruch 1 möglichst zu verbessern.task The present invention is therefore a measuring device according to the preamble of Claim 1 possible to improve.
Gelöst wird diese Aufgabe durch die Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den jeweiligen Unteransprüchen.Is solved This object is achieved by the features of claim 1. Further developments The invention will become apparent from the respective dependent claims.
Nach der Erfindung ist eine zwischen Scheibenoberkante und dem mit der Scheibenoberkante zusammenwirkende Dichtung am Türrahmen bzw. der Karosserie einsetzbare Federwage vorgesehen, die aus einem oberen und einem unteren Träger besteht, welche entgegen der Kraft wenigstens eines Federmittels gegeneinander bewegt werden können. Die Abstandsänderung zwischen oberen und unteren Träger bei Blockieren der Scheibe im Vergleich zum Abstand im entlasteten Zustand ist somit ein Maß für die vom Fensterheberantrieb aufgebrachte Kraft.To the invention is an intermediate disc top and the with the Disc top edge cooperating seal on the door frame or the body usable spring carriage provided, consisting of an upper and a lower carrier which is contrary to the force of at least one spring means can be moved against each other. The distance change between upper and lower carrier when blocking the disc compared to the distance in the unloaded Condition is thus a measure of the Power window drive applied force.
Gemäß einer bevorzugten Ausführungsform der Erfindung besteht die Meßvorrichtung aus einem oberen und einem unteren Träger, welche über jeweils an den Enden angeordnete Geradführungen relativ zueinander beweglich gelagert sind. Den beiden Geradführungen ist jeweils eine Druckfeder zugeordnet, welche die beiden Träger entgegen deren Kraft in eine Ausgangsposition drücken und entgegen derer die Scheibe bis zum Stillstand zu verfahren ist. Bei geeigneter Wahl der Federkonstanten der beiden parallelen Druckfedern ist so die Überschußkraft einfach in cm ablesbar. Vorzugsweise werden Federn mit einer Federkonstante von 5 N/mm verwendet. Die beim Blockieren der Scheibe vorliegende Überschußkraft in N ergibt sich somit aus der Abstandsänderung der Träger gegenüber der unbelasteten Normalposition gemessen in 0.1 mm.According to one preferred embodiment of Invention consists of the measuring device from an upper and a lower support, which over each at the ends arranged linear guides relative are mounted to each other movable. The two straight lines in each case a compression spring is assigned, which counteract the two carriers whose force press into a starting position and against which the Slice to a standstill is to proceed. With a suitable choice the spring constant of the two parallel compression springs so the excess force is easy in cm readable. Preferably, springs with a spring constant used of 5 N / mm. The existing in blocking the disc excess force in N thus results from the change in distance of the carrier relative to the unloaded normal position measured in 0.1 mm.
