Abstract[German]
Die Erfindung betrifft eine Spindelmutter (8) für einen elektromechanischen Linearaktuator (1), insbesondere Bremskrafterzeuger oder Bremskraftverstärker eines Kraftfahrzeugbremssystems, mit einem Basiskörper (12), der ein Innengewinde (9) für eine Spindel (7) und ein Außengewinde (15) für einen Antriebsmotor (6) aufweist. Es ist vorgesehen, dass der Basiskörper (12) aus Kunststoff gefertigt ist und dass auf den Basiskörper (12) eine im Verhältnis zum Basiskörper (12) steifere Hülse (17) zumindest im Wesentlichen spielfrei aufgeschoben und in Umfangsrichtung formschlüssig mit dem Basiskörper (12) verbunden ist.[English]
The invention relates to a spindle nut (8) for an electromechanical linear actuator (1), in particular a brake force generator or brake booster of a motor vehicle brake system, having a base body (12), which has an internal thread (9) for a spindle (7) and an external thread (15) for a drive motor (6). It is provided that the base body (12) is made of plastic, and a sleeve (17), which is stiffer in relation to the base body (12), is pushed onto the base body (12) at least substantially without play and is connected to the base body (12) in a form-fitting manner in the circumferential direction.[French]
L'invention concerne un écrou à broche (8) pour un actionneur linéaire électromécanique (1), en particulier un générateur de force de freinage ou un servofrein d'un système de freinage de véhicule automobile, comportant un corps de base (12) qui présente un filetage interne (9) pour une broche (7) et un filetage externe (15) pour un moteur d'entraînement (6). Selon l'invention, le corps de base (12) est constitué de matière plastique, et un manchon (17), plus rigide que le corps de base (12), est poussé sur ledit corps (12) au moins sensiblement sans jeu et relié audit corps (12) par complémentarité de forme dans la direction circonférentielle.
