Abstract

L'invention concerne un piston (1) configuré pour être monté autour d'un axe de rotation (O) dans un mécanisme d'embrayage pour véhicule, le piston (1) comportant : - une portée d'élongation axiale (11) comprenant un anneau d'actionnement (11 A) destiné à engager un empilement de disques d'un embrayage du mécanisme d'embrayage, - une portée d'élongation radiale (12), - des premiers moyens de connexion (11B) s'étendant depuis l'anneau d'actionnement (11 A) et/ ou des deuxièmes moyens de connexion (12B) s'étendant au moins en partie axialement depuis la portée d'élongation radiale (12), les premiers et/ou deuxièmes moyens de connexion (11B, 12B) étant agencés pour relier la portée d'élongation axiale (11) à la portée d'élongation radiale (12), la portée d'élongation axiale (11) et la portée d'élongation radiale (12), délimitant à l'état assemblé ensemble les premiers et/ou deuxièmes moyens de connexion (11B, 12B) des ouvertures (10C).The invention relates to a piston (1) configured to be mounted around an axis of rotation (O) in a clutch mechanism for a vehicle, the piston (1) comprising: - an axial elongation bearing surface (11) comprising an actuating ring (11 A) intended to engage a stack of disks of a clutch of the clutch mechanism, - a radial elongation surface (12), - first connection means (11B) extending from the actuating ring (11 A) and / or the second connection means (12B) extending at least partially axially from the radial elongation surface (12), the first and / or second connection means ( 11B, 12B) being arranged to connect the axial elongation range (11) to the radial elongation range (12), the axial elongation range (11) and the radial elongation range (12), delimiting at the assembled state together the first and / or second connection means (11B, 12B) of the openings (10C).
