Description
Die Erfindung betrifft eine Heizmanschette für die Vulkanisation eines Schlauchrollbalges einer Luftfeder aus elastomerem Material mit Verstärkungseinlagen. Weiter betrifft die Erfindung einen Schlauchrollbalg für eine Luftfeder für Fahrzeuge aus elastomerem Material mit Verstärkungseinlagen.The invention relates to a heating jacket for the vulcanization of a hose roll of an air spring made of elastomeric material with reinforcing inserts. Furthermore, the invention relates to a hose roll for an air spring for vehicles made of elastomeric material with reinforcing inserts.
Luftfedereinrichtungen, auch kurz Luftfedern genannt, die zwischen Fahrwerk und Karosserie eingespannt sind und die einen Schlauchrollbalg (Luftfederbalg) aufweisen, der wiederum zwischen einem z. B. fahrwerkseitigen Luftfederdeckel und einem karosserieseitigen Abrollkolben befestigt ist, sind in einer Vielzahl von Ausführungen bekannt. Die Luftfeder steht im Betrieb unter einem inneren Überdruck. Der Schlauchrollbalg rollt unter Last und bei Federbewegungen unter Bildung einer Rollfalte auf der Außenkontur eines konzentrischen Bauteiles ab, üblicherweise auf dem Luftfederkolben/Abrollkolben. Eine derartige Luftfeder wird häufig in Straßen- oder Schienenfahrzeugen eingesetzt, um eine komfortable Federung zu erreichen. Die Luftfeder steht im Betrieb unter einem inneren Überdruck.Air spring devices, also called short air springs, which are clamped between the chassis and body and have a Schlauchrollbalg (air bag), which in turn between a z. B. chassis-side air spring cover and a body-side rolling piston is fixed, are known in a variety of designs. The air spring is in operation under an internal overpressure. The hose roll rolls under load and spring movements to form a rolled fold on the outer contour of a concentric component, usually on the air spring piston / rolling piston. Such air spring is often used in road or rail vehicles to achieve a comfortable suspension. The air spring is in operation under an internal overpressure.
Der Schlauchrollbalg besteht aus vulkanisierten Kautschukmischungen (Gummi), die mit Festigkeitsträgerlagen verstärkt sind. Er wird in der Regel durch Vulkanisation auf einem Metallheizdorn und über eine von außen aufgebrachte Heizmanschette vulkanisiert. Bei der Vulkanisation können auf dem Schlauchrollbalg Oberflächenfehler entstehen, wenn Luft zwischen dem Schlauchrollbalg und der Heizmanschette eingeschlossen ist. Diese Einschlüsse führen zu einem sichtbaren Fehlerbild auf der Oberfläche des Schlauchrollbalges. Unter Umständen können diese Oberflächenfehler zu einer Veränderung der Schlauchrollbalgeigenschaften führen.The hose roll consists of vulcanised rubber compounds (rubber) reinforced with reinforcement layers. It is usually vulcanized by vulcanization on a metal heating mandrel and an externally applied heating sleeve. During vulcanization, surface defects may occur on the hose bladder if air is trapped between the hose bladder and the heating jacket. These inclusions lead to a visible fault pattern on the surface of the hose roll bellows. Under certain circumstances, these surface defects can lead to a change in the hose roll properties.
Aufgabe der Erfindung ist es daher, eine dahin gehend verbesserte Heizmanschette sowie einen verbesserten Schlauchrollbalg anzubieten.The object of the invention is therefore to provide an improved heating jacket as well as an improved flexible hose.
Die der Erfindung zugrunde liegende Aufgabe wird mit den Merkmalen der unabhängigen Patentansprüche 1 und 7 gelöst. Bevorzugte Ausführungsformen der Erfindung sind in den abhängigen Patentansprüchen angegeben.The object underlying the invention is achieved with the features of the independent claims 1 and 7. Preferred embodiments of the invention are indicated in the dependent claims.
Erfindungsgemäß weist die Heizmanschette eine Innenmantelfläche auf, welche derart ausgestaltet ist, dass bei einer Vulkanisation des Schlauchrollbalges eine Luftabführung zwischen Heizmanschetteninnenseite und Schlauchrollbalgaußenseite verbessert ist. Lufteinschlüsse können hierdurch derart reduziert werden, dass die beschriebenen Oberflächenfehler auf dem Schlauchrollbalg vermieden werden.According to the invention, the heating sleeve has an inner circumferential surface which is configured in such a way that an air discharge between the inner side of the heating sleeve and the outer side of the flexible hose is improved during vulcanization of the flexible hose. Air pockets can hereby be reduced in such a way that the described surface defects on the hose roll are avoided.
Der Schlauchrollbalg gemäß Patentanspruch 7 weist erfindungsgemäß eine Außenmantelfläche mit einen Muster aus Erhöhungen und Vertiefungen auf.The hose bellows according to claim 7, according to the invention has an outer circumferential surface with a pattern of elevations and depressions.
Im Folgenden werden bevorzugte Ausführungsformen der Erfindung anhand der folgenden Zeichnungen näher erläutert.In the following, preferred embodiments of the invention are explained in more detail with reference to the following drawings.
