Die !Teuerung "betrifft eine ^Rotationsdichtung, insbesondere eine zwisehen eine» Fahrzeugrad und einem feststehenden Druckl-uftanschluß angeordnete Dichtung.The "increase in price" concerns a rotary seal, especially one between two a »vehicle wheel and a fixed compressed air connection Poetry.
Gemäß der Neuerung kommt ein elastiscli verformbarer Dichtungsring mit im wesentlichen flach rechteckigem Querschnitt zur Anwendung, wobei der eine Band des Binges fest, z.B. durch "Verklemmen mit dem einen der "beiden miteinander abzudichtenden Teile verbunden ist, während der andere Band des Dichtungsringes mit Vorspannung zwischen parallelen oder im wesentlichen, parallelen Flächen der "beiden Teile des Dichtungsgehäuses angeordnet ist* Diese Dichtung ist besonders wirksam und die hierzu erforderlichen technischen Mittel können dann einfach gestaltet werden, wenn der Dichtungsring Kreisringform erhält, an seinem äußeren tJmfang befestigt und in einer zur Botationsach.se senkrechten Ebene angeordnet ist*According to the innovation, an elastically deformable sealing ring comes with it essentially flat rectangular cross-section for use, wherein one band of the binge tight, e.g. by "jamming it with one the "two parts to be sealed is connected, while the other band of the sealing ring with bias between parallel or substantially parallel surfaces of the "two parts of the seal housing is arranged * This seal is particularly effective and the The technical means required for this can then be designed in a simple manner when the sealing ring is given a circular ring shape, at his attached to the outer circumference and perpendicular to the botation axis Level is arranged *
Wie Versuche ergeben haben, ist eine derartige Dichtung sowohl für gasförmige als auch für flüssige Medien, und zwar bis zu Druckunterschieden von etwa 20 at geeignet. Während einer längeren Yerauchszeii; konnten weder Undichtigkeiten festgestellt werden, noch war es erforderlieh, die Dichtung zu warten. As tests have shown, such a seal is for both gaseous as well as liquid media, up to pressure differences of about 20 at. During a prolonged period; no leaks could be found, nor was it necessary to service the seal.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An exemplary embodiment is shown in the drawing.

DaP Gehäuseteil 1 wird mittelbar oder unmittelbar an der sich drehenden fiadseheibe befestigt. Der feststehende Teil des Dichtungsgehäuses ist mit 2 bezeichnet, und er wird mittels eines Schrägschalterlagers 3 am rotierenden Seil 1 in der Weise gelagert, daß die axialen Kräfte von dem Wälzlager 3 aufgenommen werden können.DaP housing part 1 is directly or indirectly connected to the rotating fiadse disc attached. The fixed part of the seal housing is denoted by 2, and it is by means of an angular switch bearing 3 mounted on the rotating rope 1 in such a way that the axial forces can be received by the roller bearing 3.
Der Innenring des lagers 3 wird mittels Verschraubung 4 mit dem Teil 1 verbunden. Die Verbindung des Gehäuseteiles 2 mit dem Außenring dt» Wälzlagers 3 erfolgt hingegen über einen Spannring 5» äe* unter 2v±- schenechaltung einer Dichtung 6 mit dem leil 2 versehraubbar ist* Der «wischen dem Sgfünring 5 ^nd dem Seil 1 "befindliche Schleifring 8 und die Dichtungsscheibe β bewirken zusammen den fettdichten Abschluß des Kugellagerraumes.The inner ring of the bearing 3 is connected to the part 1 by means of a screw connection 4. The connection of the housing part 2 with the outer ring of the roller bearing 3 is made via a tension ring 5 »äe * under 2v ± - scheinechaltung a seal 6 with which part 2 can be screwed * the slip ring located on the wiping ring 5 and the rope 1 8 and the sealing washer β together effect the grease-tight seal of the ball bearing space.
Zwischen den Seilen 1 und 2 ist zur Abdichtung des Druckmittelkanales $ eine kreisringföimige Dichtung 10 mit im wesentlichen flach rechteckigem Querschnitt wirksam, die zweckmäßigerweise aus einem abriebfesten Werkstoff, z.B. aus Polyamiden oder Polyurethanen hergestellt wird. Der äuiere Sand de» Binges IQ ist mittels einer Verschraubung 11 fest mit dem Seil 2 verbunden, während üsx am inneren Umfang gelegene Band zwischen senkrecht zur Rotationsachse gelegenen Flächen 1 * -und 2 ♦ der feile 1 tmd 2 mit Vorspannung angeordnet ist. Die Vorspannung des zwischen den Flächen 1* und Z* gelegenen Teiles des Dichtungsringes IO wird durch Anziehen der zwischen den feilen 2 und 5 befindlichen Verschraubung erreicht. Eine zu Beginn der Inbetriebnahme wirksame Vorspannung mit Hilfe der vorerwähnten Verschraubung ist jedoch kein unbedingtes Erforderais. Eine gute Abdichtung ist vielmehr auch dann erzielbar,Between the ropes 1 and 2, a kreisringföimige seal 10 having essentially flat rectangular cross-section is effective to seal the pressure fluid passage $, which is conveniently made of an abrasion resistant material, for example polyamides or polyurethanes. The outer sand of the Binges IQ is firmly connected to the rope 2 by means of a screw connection 11, while the band on the inner circumference is arranged between surfaces 1 and 2 of the file 1 and 2 with pretensioning perpendicular to the axis of rotation. The preload of the part of the sealing ring IO located between the surfaces 1 * and Z * is achieved by tightening the screw connection located between the files 2 and 5. A pre-tensioning effective at the beginning of the commissioning with the help of the screw connection mentioned above is not an absolute requirement. Rather, a good seal can also be achieved if
wenn die Hacken 1' und 2f lediglich satt an dem Eilig IO anliegen bzw, nur eine verhältnismäßig geringe Vorspannung gewählt wird, da der zwischen den Flächen 1' und 2· gelegene Teil der Dichtung 10 auf Grund des Betriebsdruckes eine Stauchung erfährt vtnü. hierbei «ine wünschenswerte, vom Innendruck abhängige Pressung gegen, die I*lächen lr xind 2' eintritt«when the hooks 1 'and 2f are only in full contact with the Eilig IO or only a relatively low preload is selected, since the part of the seal 10 located between the surfaces 1' and 2 is compressed due to the operating pressure vtnü. here "a desirable pressure, dependent on the internal pressure, against which the surface l r xind 2 'occurs"
