Patent ID: 8443949

Claim:
A mechanical actuator cartridge ( 22 ) for a motor vehicle brake, comprising: a cartridge body ( 24 ) with an overall shape exhibiting symmetry of revolution about an axis (X), a rotary control plate ( 28 ), housed in the cartridge body ( 24 ), a push plate ( 30 ), housed in the cartridge body ( 24 ), collaborating with the control plate ( 28 ) via means ( 20 ) that convert the rotational movement of the control plate ( 28 ) into a translational movement of the push plate ( 30 ), elastic means ( 38 ) of compressing the push plate ( 30 ) towards the control plate ( 28 ), and a cage ( 40 ) for holding the elastic means ( 38 ), the elastic means ( 38 ) extending between a first seat ( 38 A) borne by the cage ( 40 ) and a second seat ( 38 B) borne by the push plate ( 30 ), in which: the cartridge body ( 24 ) comprises at least one projection ( 42 ) for attaching the cage ( 40 ) to the body ( 24 ), and the cage ( 40 ) comprises at least one axial tab ( 44 ) comprising an attachment orifice ( 46 ) capable of collaborating with the attachment projection ( 42 ) to attach this cage ( 40 ) to the cartridge body ( 24 ), the cage ( 40 ) is capable of rotational movement about the axis (X) of the cartridge body ( 24 ), between an attachment position in which the attachment orifice ( 46 ) collaborates with the attachment projection ( 42 ), and a release position in which the cage ( 40 ) is released from the body ( 24 ), and the cartridge body ( 24 ) comprising at least one first circumferential limit stop ( 50 ) for limiting the rotation of the cage ( 40 ), the axial tab ( 44 ) of the cage ( 40 ) being capable of collaborating with the first limit stop ( 50 ) when the cage ( 40 ) is in its release position, characterized in that the cartridge body ( 24 ) comprises a ramp-forming projection ( 60 ), adjacent to the first limit stop ( 50 ), such that when the cage ( 40 ) is in the release position, the axial tab ( 44 ) rests radially both against the attachment projection ( 42 ) and against the ramp-forming projection ( 60 ).
