The invention concerns a braking system in which a spring (3) disposed in a housing (2) engages with spring force on a movable carrier plate (4) and holds the latter in a braking position, brake linings (5) disposed on the carrier plate (4) being urged against a brake disc (6). An air gap (7) between the housing (2) and carrier plate (4) corresponds to the path covered by the carrier plate (4), which is guided by means of peripheral guide bolts (8), when a coil (9) disposed in the housing (2) has been deactivated. When the coil (9) is activated, the electromagnetic force of the coil (9) counteracts the spring force. The carrier plate (4) is thus moved into the output position, which is monitored by a microswitch (10). A potentiometer (11) with a slider (12), which is moved by means of the carrier plate (4), is provided for monitoring the position of the carrier plate (4). The output resistance of the potentiometer (11, 12) thus varies in a linear manner with the movement of the carrier plate (4).
L'invention concerne un système de freinage dans lequel un ressort (3) monté dans un boîtier (2) agit avec une force de ressort sur un plateau support (4) mobile et le maintient dans une position de freinage, des garnitures de frein (5) montées sur le plateau support (4) étant comprimées contre un disque de frein (6). Un entrefer (7) entre le boîtier (2) et le plateau support (4) correspond au trajet parcouru par le plateau support (4) guidé à l'aide de broches-guides (8) périphériques, après désactivation d'une bobine (9) placée dans le boîtier (2). Lorsque la bobine (9) est activée, sa force électromagnétiue agit à l'encontre de la force du ressort. Le plateau support (4) est alors amené en position de repos, contrôlée par un microcommutateur (10). Pour contrôler la position du plateau support (4), il est prévu un potentiomètre (11) muni d'un curseur (12), déplacé à l'aide du plateau support (4). La résistance de sortie du potentiomètre (11, 12) varie ainsi de manière linéaire avec le mouvement du plateau support (4).
