Abstract

A description is given of a hydraulic vane-type shock absorber with a stator (1) in the form of a housing filled with a damping-medium dispersion (2), and with a rotor having a vane (5), the spindle (3) of the rotor being passed out of the stator (1) at the top and at the bottom through covers. The shock absorber is characterised in that at least one vane (5) and one plate cam (6) are connected to the spindle (3) of the rotor, in that a divider (4) with a slot (4a) divides the cylindrical space in the stator (1) into two chambers a, b, and an opening for an adjusting element (8) passes through the stator wall, and in that the slot (4a) is dimensioned in such a way that a gap for the throughflow of the damping-medium dispersion (2) can be set between the plate cam (6) and the adjusting element (8). The shock absorber has the advantage that it is simple to produce and very reliable in operation (Fig. 1). <IMAGE>

Description

Technischer StandTechnical status

Überall in der Technik, sei es bei Maschinen, Geräten, Fahrzeugen werden Teile bewegt und entstehen Schwingungen, die abgebaut werden müssen, um Schäden zu vermeiden.Everywhere in technology, be it machines, devices, Parts of vehicles are moved and vibrations occur, that must be dismantled to avoid damage.

Gelöst werden diese Probleme meist mit linear arbeitenden Dämpfern mit Zylinderrohr, Kolbenstange usw., wobei dünn­ flüssige Öle über kleine Spalten und Ventile mit hoher Präzision verdrängt werden und Bewegungsenergie in Wärme umwandeln.These problems are mostly solved with linear working Dampers with cylinder tube, piston rod etc., being thin liquid oils through small gaps and valves with high Precision are displaced and kinetic energy in heat convert.

Obwohl ein sehr großer Teil der Bewegungen rotatorischen Ursprung hat, gibt es keinen Torsionsdämpfer als Baureihe für die verschiedensten Einsätze.Although a very large part of the rotatory movements Origin, there is no torsion damper as a series for a wide variety of uses.

Trotz umfangreicher Recherchen und Studium von Patentan­ meldungen sind außer Speziallösungen, z. B. Laufraddämpfer für Kettenfahrzeuge und Türschließer nichts Bedeutendes be­ kannt, die aber alle mit Flüssigkeiten und deren Nachteile arbeiten oder mit Medien, welche die hohen Anforderungen hinsichtlich Wärmestabilität und Viskosität an ein solches Dämpfmittel nicht erfüllen.Despite extensive research and studying Patentan messages are apart from special solutions, e.g. B. Impeller damper nothing important for tracked vehicles and door closers knows, but all with liquids and their disadvantages work or with media that meet the high requirements in terms of thermal stability and viscosity of such Do not meet damping agents.

AufgabenstellungTask

Aufgabe der Erfindung ist es einen Drehflügelstoßdämpfer zu schaffen, der sehr einfach aufgebaut ist, den unterschied­ lichen Anforderungen entsprechend preiswerte Konstruktionen zu schaffen, die hohen, temperaturbedingten Schwankungen nicht entstehen zu lassen, bzw. auszugleichen, was nur durch das Zusammenwirken von Spezialdämpfungsdispersion und Torsionsmechanik erreichbar ist und damit auch Baureihen für den Markt geschaffen werden können.The object of the invention is to provide a wing damper create that is very simple, make the difference according to inexpensive constructions to create the high, temperature-related fluctuations not to let arise or to compensate for what only through the interaction of special damping dispersion and Torsion mechanics is achievable and thus also for series the market can be created.
