Abstract

A railway carriage is fitted with folding panels e.g. beds, seats, luggage racks and so forth which are supported or steadied by pre-compressed telescopic dampening components. During installation or removal of the dampeners, they are compressed by a tool (1), one end of which terminates in a U-shaped profile. The fitting tool esp. has a helical spindle (6) for telescopic compression or decompression under controlled conditions.

Vorrichtung zum Vor- und Entspannen von TeleskopdämpfernDevice for pre-tensioning and relaxing telescopic dampers

Die Erfindung betrifft eine Vorrichtung zum Vor- und Entspannen von Teleskopdämpfern in und/oder aus vorzugsweise Fahrzeugen aller Art oder anderen Einrichtungen.The invention relates to a device for pre-tensioning and relaxing telescopic dampers in and/or from preferably vehicles of all types or other devices.

In nahezu allen Fahrzeugen sind zur Dämpfung und/oder zum öffnen von Luken, Klappen etc. sowie zum Abfedern von ausklappbaren Objekten, wie beispielsweise Wandbetten in Eisenbahnfahrzeugen oder in Möbeln oder dgl. Teleskopdämpfer integriert. Die Verbindungsglieder der Teleskopdämpfer sind oftmals aus Gussmaterial und in einer sehr unzureichenden Art und Weise am eigentlichen Dämpfungskörper befestigt. Beim Auftreten von Querkräften neigen diese Verbindungsglieder zum vorzeitigen Versagen in Folge Abscherens. Die Teleskopdämpfer müssen dann aus oftmals räumlieh sehr beengten Verhältnissen ausgebaut, ausgetauscht und anschließend wieder eingebaut werden. Da die Teleskopdämpfer im Einbauzustand unter erheblichen Druck stehen, ist das Ein- und/oder Ausbauen nicht ohne weiteres möglich und mit erheblichen Anstrengungen verbunden.Telescopic dampers are integrated into almost all vehicles for damping and/or opening hatches, flaps, etc. and for cushioning fold-out objects such as wall beds in railway vehicles or in furniture or similar. The connecting links of the telescopic dampers are often made of cast material and are attached to the actual damping body in a very inadequate manner. When transverse forces occur, these connecting links tend to fail prematurely as a result of shearing. The telescopic dampers then have to be removed from often very cramped conditions, replaced and then reinstalled. Since the telescopic dampers are under considerable pressure when installed, installing and/or removing them is not easy and involves considerable effort.

Bekannt ist eine Spannvorrichtung für einen Antriebsriemen, eine Antriebskette oder dgl., mit einem schwenkbar an einem feststehenden Teil gelagerten Spannarm (DE 38 12 375 A1). Bei der Vorrichtung ist ein Teleskopdämpfer zwischen einer äußeren Befestigungsstelle des schwenkbaren Teiles und dem Gehäuse der Brennkraftmaschine angeordnet, der schwer erreichbar ist.A tensioning device for a drive belt, a drive chain or the like is known, with a tensioning arm pivotably mounted on a fixed part (DE 38 12 375 A1). In the device, a telescopic damper is arranged between an outer fastening point of the pivotable part and the housing of the internal combustion engine, which is difficult to reach.

Des weiteren ist eine Federspannvorrichtung zum Montieren oder Demontieren der Stoßdämpfer an Kraftfahrzeugen bekannt (DE 697 00 396 T 2).Furthermore, a spring tensioning device for mounting or dismounting shock absorbers on motor vehicles is known (DE 697 00 396 T 2).

Die DE 42 13 101 C2 beschreibt eine Hinterachsaufhängung für Kraftfahrzeuge, wobei eine Möglichkeit beschrieben wird Stoßdämpfer aus einer Hinterachsaufhängung von Autobussen ein- und auszubauen.
Die Vorrichtung ist nur für den Einsatz an Autobussen geeignet und nicht für andere Teleskopdämpfer verwendbar.DE 42 13 101 C2 describes a rear axle suspension for motor vehicles, describing a possibility for installing and removing shock absorbers from a rear axle suspension of buses.
The device is only suitable for use on buses and cannot be used for other telescopic dampers.

Der Erfindung liegt die Aufgabe zugrunde, eine Teleskopdämpferwechselvorrichtung zu entwickeln, die für nahezu alle Teleskopdämpferarten geeignet, mit wenig Aufwand herstellbar und einfach in der Bedienung ist. Dabei soll der Teleskopdämpfer im eingespannten Zustand ein- und ausgebaut werden.The invention is based on the task of developing a telescopic damper changing device that is suitable for almost all types of telescopic dampers, can be manufactured with little effort and is easy to operate. The telescopic damper should be installed and removed in the clamped state.

Die Vorrichtung zum Vor- und Entspannen von Teleskopdämpfern weist eine muldenförmige Spanneinrichtung (1) auf, die als an den Enden geschlossenes U-Profil (2) ausgebildet ist (Fig. 1). Während an einem Ende des U-Profiles (2) eine Einspannung (5) zur Aufnahme eines zapfenartigen Verbindungsglifcdes (3) des Teleskopdämpfers (4) angeordnet ist, weist das andere Ende des U-Profiles (2) eine Gewindeöffnung (17) zur Aufnahme eines spindelförmigen Stellgliedes (6) auf (Fig. 2). Das spindelförmige Stellglied (6) besitzt an seinem - im U-Profil (2) befindlichen - Teil einen Spannschlitten (8), der den vorzugsweise gabelförmig ausgebildeten Teil des Teleskopdämpfers (4) aufnimmt. Der gabelförmige Teil des Teleskopdämpfers (4) wird mittel eines Stiftes oder einer Schraube am Spannschlitten (8) befestigt. The device for pre-tensioning and relaxing telescopic dampers has a trough-shaped clamping device (1) which is designed as a U-profile (2) closed at the ends (Fig. 1). While a clamping device (5) for receiving a pin-like connecting link (3) of the telescopic damper (4) is arranged at one end of the U-profile (2), the other end of the U-profile (2) has a threaded opening (17) for receiving a spindle-shaped actuator (6) (Fig. 2). The spindle-shaped actuator (6) has a clamping slide (8) on its part located in the U-profile (2), which receives the preferably fork-shaped part of the telescopic damper (4). The fork-shaped part of the telescopic damper (4) is attached to the clamping slide (8) by means of a pin or a screw.
