Title
(DE) LASTDRUCKBREMSE
(EN) AUTOMATIC MECHANICAL BRAKE
(FR) FREIN ACTIONNE PAR LA CHARGE
Abstract
(DE)
Die Erfindung bezieht sich auf eine Lastdruckbremse, die ein Sperrteil (7), zwei Bremsbacken (20, 21) und ein Bremsteil (32) enthält, wobei die Bremsbacken (20, 21) zwischen dem Sperrteil (7) und dem Bremsteil (32) so verkeilt werden, daß sich das Lastdrehmoment nicht auf die Antriebsseite überträgt. Bei einem von der Antriebsseite wirkenden Drehmoment wird die Verkeilung mit minimal erforderlichem Losreißmoment gelüftet.
(EN)
The invention relates to an automatic mechanical brake having a locking member (7), two brake shoes (20, 21) and a brake component (32), in which the brake shoes (20, 21) are wedged between the locking member (7) and the brake component (32) in such a way that the load torque is not transferred to the drive side. With a torque acting from the drive side, the wedging is released with the minimum necessary pull-off moment.
(FR)
L'invention concerne un frein actionné par la charge qui comprend un élément de fermeture (7), deux mâchoires de frein (20, 21) et un élément de freinage (32). Les mâchoires de frein (20, 21) sont calées entre les éléments de fermeture (7) et l'élément de freinage (32) de manière que le couple de charge ne soit pas transféré au côté entraînement. Lorsque le couple agit depuis le côté entraînement, le calage est débloqué avec un moment d'arrachement de force minimale.
