Title
(DE) MEHRSCHICHTIGER FLEXIBLER SCHLAUCH
(EN) MULTI-LAYER FLEXIBLE HOSE
(FR) TUYAU FLEXIBLE MULTICOUCHE
Abstract
(DE)
Die Erfindung betrifft einen mehrschichtigen flexiblen Schlauch, insbesondere einen mehrschichtigen flexiblen Bremsschlauch. Um eine gleichmäßige Volumenzunahme über den gesamten Druckbereich von 0 bis 200 bar und über den gesamten Temperaturbereich von –40 °C bis 160°C zu gewährleisten, weist der Schlauch folgenden Schichtenaufbau auf: - eine einlagige oder mehrlagige Außenschicht auf Basis wenigstens eines Elastomers; - eine erste einlagige oder mehrlagige textile Festigkeitsträgerschicht aus Polyvinylalkohol und/oder Rayon; - eine zweite einlagige oder mehrlagige textile Festigkeitsträgerschicht aus Aramid; - eine einlagige oder mehrlagige Innenschicht auf Basis wenigstens eines Elastomers.
(EN)
The invention relates to a multi-layer flexible hose, in particular a multi-layer flexible brake hose. In order to guarantee a uniform volume increase over the entire pressure range from 0 to 200 bar and over the entire temperature range from -40°C to 160°C, the hose has the following layer structure: a single-ply or multi-ply outer layer based on at least one elastomer; a first single-ply or multi-ply textile reinforcing layer made of poly(vinyl alcohol) and/or rayon; a second single-ply or multi-ply textile reinforcing layer made of aramid; and a single-ply or multi-ply inner layer based on at least one elastomer.
(FR)
L'invention concerne un tuyau flexible multicouche, en particulier un flexible de frein multicouche. L'objectif de l'invention est de garantir une augmentation de volume homogène sur l'ensemble de la plage de pressions de 0 à 200 bar et sur l'ensemble de la plage de températures de –40 °C à 160 °C. A cet effet, le flexible présente la structure stratifiée suivante : une couche extérieure en une seule épaisseur ou en plusieurs épaisseurs à base d'au moins un élastomère ; une première couche de renfort textile en une seule épaisseur ou en plusieurs épaisseurs à base de polyalcool de vinyle et/ou de rayonne ; une deuxième couche de renfort textile en une seule épaisseur ou en plusieurs épaisseurs à base d'aramide ; une couche intérieure en une seule épaisseur ou en plusieurs épaisseurs à base d'au moins un élastomère.
