Title
(DE) ELEKTROMECHANISCHE BREMSVORRICHTUNG
(EN) ELECTROMAGNETIC BRAKE SYSTEM

Abstract
(DE)
Der Erfindung betrifft eine elektromechanische Bremsvorrichtung (50). Zur Betätigung einer Scheibenbremse (52) weist sie zwei Elektromotoren (86, 92) auf, deren Drehbewegungen mittels eines einen Differentialantrieb bildenden Rollengewindetriebs (60) überlagert und in eine Linearbewegung umgesetzt werden. Durch Antrieb mit beiden Elektromotoren (86, 92) läßt sich ein Lüftspiel der Scheibenbremse (52) schnell überwinden und anschließend nach Stillsetzung eines Elektromotors (86, 92) mit dem das größere Untersetzungsverhältnis aufweisenden Elektromotor (92, 86) eine hohe Bremskraft erzeugen. Weiterer Vorteil ist die Systemredundanz, womit gemeint ist, daß sich die Bremsvorrichtung (50) bei Ausfall eines Elektromotors (86, 92) mit dem anderen Elektromotor (92, 86) vollständig lösen läßt.
(EN)
The invention relates to an electromagnetic brake system (50). To actuate a disk brake (52), the brake system is provided with two electric motors (86, 92) whose rotary movements are superimposed by a threaded roller gear (60) which forms a differential drive system and converted to linear motion. Using both electric motors (86, 92) as drives facilitates rapid correction of clearance and subsequently, once one electric motor (86, 92) has been switched off, generation of a high braking force with the electric motor (92, 86) which has the higher step-down ratio. Another advantage is the system redundancy, i.e. in the event of failure of one of the electric motors (86, 92) the brake system (50) can be fully released by the other motor.
(FR)
La présente invention concerne un système de freinage électromécanique (50). Pour actionner un frein à disque (52), on utilise deux moteurs électriques (86, 92) dont les mouvements rotatifs sont superposés par un mécanisme fileté à rouleaux (60) constituant un entraînement différentiel et transformés en mouvement linéaire. L'entraînement par les deux moteurs électriques (86, 92) permet d'éliminer rapidement le jeu de frein à disque (52) pour produire ensuite une force de freinage élevée avec le moteur électrique (92, 86) qui présente le plus grand rapport de réduction après l 'arrêt d'un moteur électrique (86, 92). Un autre avantage réside dans la redondance système, c'est-à-dire que, en cas de panne d'un moteur électrique (86, 92), le desserrage du système de freinage (50) fonctionne entièrement avec l'autre moteur électrique (92, 86).
