Abstract

La présente invention concerne un frein à disque de sécurité, normalement serré. Le frein comporte un châssis, deux bras de serrage et dans un mode de réalisation préférentiel un électro-aimant de manoeuvre. Il comporte aussi un dispositif de rattrapage de jeu de l'usure des garnitures. Ce dispositif est constitué d'un détecteur amplificateur de jeu d'usure 90, limiteur de course 94, 96, 98 d'un organe de commande 92, 88 coopérant par un encliquetage 64, 110 avec un manchon de longueur variable 56, 60, 84 intégré à la chaîne cinématique de serrage. Ce dispositif agit au desserrage, hors charge et permet une action manuelle d'urgence. Application aux freins de sécurité de matériel lourd de manutention.The present invention relates to a safety disc brake, normally applied. The brake comprises a frame, two clamping arms and, in a preferred embodiment, an operating electromagnet. It also includes a device for adjusting the wear of the linings. This device consists of an amplifier of wear clearance 90, stroke limiter 94, 96, 98 of a control member 92, 88 cooperating by a snap 64, 110 with a sleeve of variable length 56, 60, 84 integrated into the tightening kinematic chain. This device acts on release, without load and allows emergency manual action. Application to the safety brakes of heavy handling equipment.
