Description

Durch flüssige oder gasförmige Druckmittel bewegte Bremseinrichtung, insbesondere für Vierradbremsen von Kraftfahrzeugen. Das Wesen der Erfindung besteht in einer Verbesserung einer durch flüssige oder gasförmige Druckmittel bewegten Bremseinrichtung, insbesondere für Vierradbremsen von Kraftfahrzeugen nach Patent 451 o28.Brake device moved by liquid or gaseous pressure medium, especially for four-wheel brakes of motor vehicles. The essence of the invention consists in an improvement of a moving by liquid or gaseous pressure medium Braking device, in particular for four-wheel brakes of motor vehicles according to patent 451 o28.

Abb. i zeigt eine solche Bremse an der Hinterachse eines Kraftwagens im Schnitt mit denselben Buchstabenbezeichnungen, wie sie die Patentschrift 451 o28 aufweist. W ist die Hinterachswelle, auf der das zylindrisdhe Stück G2 verkeilt ist, welches als Auflagefläche für das mit der Welle W sich drehende, abnehmbare Rad Ri dient. Das feststehende Achsgebäuse G hat einen zylindrischen Ansatz G, mit dem das Stück A verkeilt ist. Auf diesem Stück A, welches Achsialnuten hat und Kolbenringe K, KZ als Abdichtungen trägt, sind achsial verschiebbar, aber nicht drehbar die beiden Bremsscheiben B, B, angeordnet, welche außen Bremsbeläge K tragen, die gegen entsprechende Bremsbeläge K am abnehmbaren Scheibenrade R, bzw. an Bremstrommel R2 gepreßt werden.Fig. I shows such a brake on the rear axle of a motor vehicle in section with the same letter designations as the patent specification 451 o28 has. W is the rear axle shaft on which the cylindrical piece G2 is wedged is, which as a support surface for the rotating with the shaft W, removable Rad Ri serves. The fixed axle housing G has a cylindrical extension G, with to which the piece A is wedged. On this piece A, which has axial grooves and piston rings K, KZ as seals are axially displaceable, but not rotatable two brake disks B, B arranged, which wear the outside brake pads K against Corresponding brake pads K on the removable disc wheel R or on the brake drum R2 to be pressed.

Das Neue besteht darin, daß zur Begrenzung des unter der Wirkung der Rückstellfedern erfolgenden Hubes der beiden Bremsscheiben an dem mit dem Achsgehäuse G verbundenen Teil A Anschläge A, AZ in den Achsialnuten oder am entsprechendenFlanschansatz A3 vorgesehen sind. Die beiden Bremsscheiben werden in die Leerlauf stellung durch zwei Federn F, und F, zurückgeführt und in dieser Stellung sicher dadurch erhalten, daß sie sich entweder gegen die Enden A, undA2 in den Achsialnuten legen oder gegen einen entsprechenden Planschansatz A3 des Stükkes A (vgl. Abb. i untere Hälfte). Auf diese Weise erhält man eine sehr schmale Bauart einer doppelwirkenden entlasteten Bremse.What is new is that to limit what is under the action of Return springs taking place the stroke of the two brake disks on the one with the axle housing G connected part A, stops A, AZ in the axial grooves or on the corresponding flange attachment A3 are provided. The two brake discs are in the neutral position two springs F, and F, returned and safely retained in this position, that they either lie against the ends A and A2 in the axial grooves or against a corresponding paddling approach A3 of the piece A (see Fig. i lower half). In this way you get a very narrow design of a double-acting relieved Brake.

In Abb. i ist noch eine Neuerung dargestellt, und zwar eine Art, wie ein einteiliges offenes Scheibenrad in einfacher Weise in ein zweiteiliges geschlossenes Scheibenrad umgeändert werden kann, das innen die Bremsbeläge K enthält, dadurch, daß man, wie in Abb. i in punktierten Linien dargestellt, unter Fortfall der zylindrischenWandRg der Bremstrommel die Seitenwand R2 der Bremstrommel verlängert bis zum Felgenflansch R4.Another innovation is shown in Fig. I, namely a way in which a one-piece open disc wheel in a simple manner in a two-piece closed Disc wheel can be modified, which contains the brake pads K inside, as a result, that, as shown in dotted lines in Fig. i, omitting the cylindrical wall Rg the brake drum extends the side wall R2 of the brake drum up to the rim flange R4.
