Abstract

L'invention se rapporte à un élément élastique (21) inséré dans un frein, notamment à disque, entre piston (23) et actionneur linéaire (22, 230) de frein de stationnement, stabilisant passivement l'effort de serrage en stationnement en absorbant ou restituant une énergie mécanique de compression. Celui-ci forme une pièce de tôle métallique élastique insérée entre partie d'appui (220) d'actionneur linéaire et (230) de piston : une partie extérieure (212) retenue par un épaulement (231) ou rétrécissement formé à l'intérieur du piston, et une partie intérieure (213, 214) recevant l'appui de l'actionneur linéaire (22) avant contact avec la partie d'appui (230) du piston lorsque l'élément élastique (21) est au repos, ménageant ainsi une course (D21) de déformation élastique pour l'actionneur linéaire lorsqu'il appuie sur le piston. De préférence, il s'agit d'un corps cylindrique (211) logé à l'intérieur (239) du piston (23) et entourant l'actionneur linéaire 22, fonctionnant ainsi en flexion et extension.The invention relates to an elastic element (21) inserted in a brake, in particular a disc brake, between piston (23) and linear actuator (22, 230) of the parking brake, passively stabilizing the clamping force in parking by absorbing or restoring a mechanical energy of compression. This forms a piece of elastic sheet metal inserted between the bearing part (220) of the linear actuator and (230) of the piston: an outer part (212) retained by a shoulder (231) or constriction formed inside of the piston, and an internal part (213, 214) receiving the support of the linear actuator (22) before contact with the support part (230) of the piston when the elastic element (21) is at rest, leaving thus a stroke (D21) of elastic deformation for the linear actuator when it presses on the piston. Preferably, it is a cylindrical body (211) housed inside (239) of the piston (23) and surrounding the linear actuator 22, thus operating in flexion and extension.
