Abstract

L’invention concerne un ensemble piston (2)/vis (3)-écrou (4) pour actionneur (1) motorisé pour frein à disque comprenant : un piston d’actionnement (2) pour au moins un patin de frein à disque, ledit piston (2) présentant un logement d’appui (22) ménagé à l’arrière de la face d’appui (21) du piston (2), un mécanisme vis (3)-écrou (4) logé dans le logement d’appui (22) du piston (2) et destiné à appliquer un effort axial de serrage sur le piston d’actionnement (2) à partir d'un entraînement rotatif, l’écrou (4) étant monté fixe en rotation à l’intérieur du logement d’appui (22) du piston (2) et entraînable en translation axiale dans ledit logement d’appui (22), l’entraînement en rotation de la vis (3) générant dans un sens une course de l’écrou (4) vers et contre la face arrière (23) de la face d’appui (21) du piston (2) pour appliquer un effort axial de poussée sur ledit piston (2) et dans le sens opposé une course pour rétracter l’écrou (4) et cesser sa poussée axiale sur le piston (2). L’invention consiste en ce que caractérisé en ce que le logement d’appui (22) du piston (2) comporte un moyen de retenue axiale (5, 51) ménagé en saillie radiale dans le logement d’appui (22) et contre lequel, lors de la course de retrait, l’écrou (4) est amené en butée pour entraîner le piston (2) avec lui en retrait. FIGURE 2The invention relates to a piston (2)/screw (3)-nut (4) assembly for a motorized actuator (1) for a disc brake comprising: an actuating piston (2) for at least one disc brake pad, said piston (2) having a bearing housing (22) formed at the rear of the bearing face (21) of the piston (2), a screw (3)-nut (4) mechanism housed in the housing support (22) of the piston (2) and intended to apply an axial clamping force on the actuating piston (2) from a rotary drive, the nut (4) being mounted fixed in rotation at the inside the bearing housing (22) of the piston (2) and drivable in axial translation in said bearing housing (22), the rotational drive of the screw (3) generating in one direction a stroke of the nut (4) towards and against the rear face (23) of the bearing face (21) of the piston (2) to apply an axial thrust force on said piston (2) and in the opposite direction a stroke to retract the nut (4) and stop its axial thrust on the piston ( 2). The invention consists in that, characterized in that the bearing housing (22) of the piston (2) comprises an axial retaining means (5, 51) provided projecting radially in the bearing housing (22) and against which, during the withdrawal stroke, the nut (4) is brought into abutment to drive the piston (2) with it retracted.
